My previous water filter took up precious refrigerator space, and I was never quite sure how well it was\npurifying my drinking water\n.\nCountertop water filters, on the other hand, promised to be a better choice for getting rid of contaminants and microplastics. According to water sommelier\nMartin Riese\n. “A good glass of\ndrinking water should be odorless\n, colorless, and will have a refreshing and crisp taste due to the minerals dissolved in the water.”\nThere are many different options at various price points, from basic, affordable filters that remove common contaminants like chlorine to reverse-osmosis systems that “filter out many contaminants like lead, PFAS and\nmicroplastics\n,” Riese says.\nWhat We Tested\nWe carefully selected the best countertop water filters for every household, taking into consideration\nfilter lifespan\n,\ncertifications\n,\nupfront and maintenance costs\n,\nwater capacity\n, and\nease of use\n. For more information on how we tested countertop water filters, check out\nour testing process\nbelow.\nWhy You Should Get It\nIt’s a plug-and-play option that is easy to use and effective, with fast purification cycles.\nKeep in Mind\nThe leftover water from each cycle might feel wasteful to some users.\nThe Bluevua Reverse Osmosis Countertop Water Filter impressed me with its ease of use and comprehensive filtration, as well as its design. It’s a plug-and-play system that took me only about 30 minutes to set up, including reading the instructions, washing the pieces, and running the system cycle several times.\nThe filter uses five levels of filtration, including a remineralization filter, to deliver purified water into a carafe made of high borosilicate glass. During testing, the filtered water came out consistently clear and clean-tasting, even with frequent cycling thanks to several teenagers and adults constantly filling travel mugs and water bottles.\nTo refill, remove the tank from the base, fill it with tap water, and replace it for another cycle. Speed is another plus with the system, as it runs a cycle in a matter of minutes. The display panel gives a clear numerical \"before\" and \"after\" reading on the front of the machine at the start and finish of each cycle.\nWe appreciate how easy the water filter system is to use, but there is a decent amount of leftover water from a cycle that is not for consumption. While I used it to water plants and mix\nhomemade cleaning solutions\n, some might find this aspect a bit wasteful. \nReplacement filters are $50 and one filter should last about a year. I found this to be pretty reasonable, especially compared to the cost of buying bottled water on a regular basis.\nProduct Details: Dimensions:\n10.9 x 15.4 x 14.3 in. |\nContaminants Removed:\nHeavy metals, lead, mercury, chlorine, PFOA, PFOS, fluoride ,sulfates |\nFiltration Process:\nReverse osmosis |\nCertifications:\nWQA, NSF, ANIS\n|\nTank Capacity:\n1.05 gal. |\nFilter Capacity:\n1,050 gal. |\nWarranty:\nOne year\nCredit: Better Homes & Gardens\nCredit: Better Homes & Gardens\nCredit: Better Homes & Gardens\nCredit: Better Homes & Gardens\nCredit: Better Homes & Gardens\nWhy You Should Get It\nThere is no tank or reservoir to fill or empty, since the system is attached to the kitchen faucet.\nKeep in Mind\nThe faucet adapter\nThe Brondell Countertop Water Filtration System is both more affordable\nand\nmore attractive than other options we tested. It’s minimal, with few controls, and matched our tester’s\nmodern kitchen decor\n. Plus, it’s compact, so it’s a good option for smaller kitchens. \nInstallation is simple—the most complicated part is attaching the faucet adapter to divert water directly from the sink, but even this took us no more than five minutes. All in all, it was about 20 minutes from opening the package to drinking our first glass of filtered water. This included running the water for 10 minutes before using.\nThe Brondell uses three stages of filtration, including a composite filter for sediments and a carbon filter to improve water taste and smell and remove VOCs and other contaminants. We noticed that the filtered water had a better overall flavor compared to the unfiltered tap, which usually tastes and smells like chlorine.\nDespite the positives, we noticed a few downsides as well. The water feed line that connects to the faucet is exposed, which wasn’t our favorite aesthetically, and though the upfront cost of the device is lower than many, the maintenance cost for buying\nreplacement filters\nis $150 a year. \nIt’s also worth noting that the faucet attachment only works with\ntraditional faucets\n, not more modern pull-out or\nspray faucets\n. You can, however, purchase a compatible\nT-valve\nthat lets you connect the filter directly to the water supply underneath the sink. \nProduct Details: Dimensions:\n10.5 x 3.75 x 13.5 in. |\nContaminants Removed:\nHeavy metals, chlorine, VOCs |\nFiltration Process:\nCarbon |\nCertifications Water Quality:\nWQA Gold Seal, NSF\/ANSI |\nTank Capacity\n: NA |\nFilter Capacity:\n5,000 gal.

We appreciated the sleek, modern design and the ability to heat the water directly using the device instead of transferring it to a kettle or microwave.\nThe filter uses a four-stage process, including a UV-C light, to remove contaminants and sediment from tap water. It arrived fully assembled—all we had to do before use was run four cycles with water to flush out the system. The filtered water appeared clearer in appearance, and the taste was slightly different.\nMaking hot water with the purifier is super easy; just place a mug on the tray and press the hot water button on the machine. The water takes a few seconds to heat up, but once it does, it’s the perfect temperature for a warm beverage. Green tea had a cleaner, less chemical taste when we prepared it with the purified water.\nWe love that the reverse-osmosis filter can last for up to two years (when most filters need to be replaced about once a year), though it’s important to note that the carbon and VOC filters need to be changed approximately every 12 months. A\npack of all three filters\nis available for $125, which is fairly cost effective.\nProduct Details: Dimensions:\n17.3 x 6.7 x 12.2 in. |\nContaminants Removed:\nFluoride, heavy metals, PFAS, antibiotics, arsenic, hormones, minerals, microplastics |\nFiltration Process:\nReverse osmosis |\nCertifications:\nNSF |\nTank Capacity:\n0.9 gal. |\nFilter Capacity:\n600 gal.

We were immediately impressed by the easy setup process, which uses color-coding to simplify the installation of the three filtration tanks.\nAfter installing the tanks, we ran four cycles (each took 10 to 15 minutes) before drinking the water, per the instructions. The water test strip we used to evaluate our tap water prior to filtration showed a high level of nitrates; when we repeated the water test after filtration, the level had gone down to zero.\nWe didn’t notice a big difference in the taste of the water after filtration, but it did seem slightly cleaner. The reservoir holds 3 quarts of filtered water (or about 12 cups); we found ourselves refilling it about every other day, which was not overly burdensome since it only takes a few minutes to filter new water.\nThe system was a nice size for our tester’s kitchen, which has plenty of counter space, but it may be too bulky for\nsmall kitchens\n. Unlike some of our other top picks, it doesn’t include a pitcher—instead, you dispense the water directly into your preferred drinking vessel. It’s worth noting that the spout is too low for larger water bottles to fit underneath.\nAs with other multi-stage models, the different filters have different expected lifespans (between six months and two years). You can purchase a\npack of replacement filters\ndesigned to last two years for $150, which we think is a pretty good value. The manufacturer suggests cleaning the reservoir about once a week.\nProduct Details: Dimensions\n14 x 12 x 14 in. |\nContaminants Removed:\nPFOA, PFOS, lead, fluoride, chlorine, microplastics |\nFiltration Process:\nReverse osmosis |\nCertifications:\nNSF |\nTank Capacity:\n1 gal. |\nFilter Capacity:\n600 gal.

The ability to produce both hot and cold water is a plus—we appreciated that we could\nmake tea\nor hot chocolate with water dispensed directly from the machine. \nThe test strips that we used during the testing period indicated that the machine, with its seven-stage filtration, effectively removed bacteria. However, the unit is on the larger side compared to others on our list and requires a considerable amount of counter space. We also found the system to be unpleasantly loud during operation. \nProduct Details: Dimensions\n18.3 x 7.8 x 17.1 in. |\nContaminants Removed:\nPFOA, PFOS, TDS, fluoride, nitrates, arsenic |\nFiltration Process:\nReverse osmosis |\nCertificatio\nns: NSF |\nTank Capacity\n: 1 gal. |\nFilter Capacity:\n500 gal.

If you’re on a tighter budget, we love the\nBrondell Cypress\n—an effective filtration system that costs less than $200.\nOur Testing Process\nTo find the best countertop water filters, we evaluated seven options based on five factors: water smell, water taste, ease of use, design, and the value for cost. \nWe first tasted our unfiltered tap water, noting any cloudiness or smell. Then we set up the devices, paying close attention to the instructions. Next we sampled the filtered water, noting changes in appearance or taste. \nAt least once during the testing period we used water test strips to compare the unfiltered tap against the filtered water. This helped us see if the filtration process removed contaminants and determine whether the results aligned with the marketing claims.  \nWe also compared upfront costs with the costs of the replacement filters to help determine a machine’s overall value.\nCredit:\nBetter Homes & Gardens\nWhat to Know About Countertop Water Filters Before Shopping\nFreestanding vs. Faucet-fed\nCountertop water filters come in a couple of variations. According to Lowe’s store manager Gary McCoy, “They may be attached directly to a faucet to provide filtered water straight from the tap or come as a standalone dispenser with a reservoir that can be placed anywhere.”\nFaucet-fed filters\nmean you don’t have to worry about manually refilling, but they tend to be less renter-friendly, as most manufacturers recommend drilling a hole in your counter to feed the tube from under the sink. This more effectively hides the unsightly water feed line. \nIf you’re\nshort on counter space\nand don’t have room right by your\nkitchen sink\n, a freestanding countertop water filter is more portable and practical. It’s also great to use on your nightstand if you’d like to have fresh water more easily accessible in the middle of the night.\nMost of the best countertop water filters on our list are freestanding, with the\nBrondell Cypress\nbeing the exception. While we enjoyed this feature, we didn’t love the visible water feed line, since we were unwilling to drill a hole through the countertop for the test. Another con is that it’s not compatible with pull-down faucets.\nDimensions\nMost countertop water filters on our list are between the size of a toaster and a larger coffee maker. In addition to counter space, you need enough clearance above the filter to fill or remove the tank. If you’re placing it underneath low kitchen cabinets, like we did with the\nSans Countertop Water Purifier\n, the appliance may need to be moved when it’s time to refill.\nCapacity\nThere are two different capacities listed for most countertop water filters—tank capacity and filter capacity. These numbers are easily confused but mean different things. Water tank capacity refers to how much filtered water the appliance can hold. The options on our list range from 0.9 to over 1 gallon.\nFilter capacity, on the other hand, indicates roughly how much water the appliance can filter effectively before it needs replacing. If you can’t find a specific number, some manufacturers list the approximate filter lifespan instead. This varies from six months to two years, and differs depending on the type of filter.\nCertifications\nThere are so many contaminants that can show up in tap water, and manufacturers make wildly different claims about what filters can reduce or eliminate. So, what’s the best countertop water filter for removing the most dangerous contaminants? And how do you know if a manufacturer’s claims are legit? \n“You can look for National Sanitation Foundation (NSF) certification, which indicates the filter has been independently tested to verify, among other things, that it reduces the contaminants it claims to reduce,” McCoy says. All of the filters on our list have the NSF certification.\nAnother common certification is from the American National Standards Institute, or ANSI. You’ll often see NSF or ANSI certifications listed with a specific number. Standards 42, 53, and 401 are considered the industry trifecta for removing tastes and odors (42), traces of medicines and other chemicals (401), and major health concerns (53) such as asbestos, lead, and mercury. \nIt’s important to look for these specific numbers if a manufacturer lists an appliance as being NSF certified to understand which contaminants the water filter will actually remove. However,\nSydney Evans\n, senior science analyst at the Environmental Working Group, notes that not all filters work on all contaminants. \n“Some organizations like NSF and WQA provide some level of third-party verification that the filter actually meets the manufacturer's claims. But it is important to find out exactly what those manufacturer's claims are when shopping for a water filter,” Evans says.\nFilter Lifespan\nLike with a water filter pitcher, the filter components don’t last forever. Most of the countertop water filters we tested estimate that you’ll need to replace the filters every six months to two years. However, many devices have multiple filters that have different requirements depending on the type. \nIt’s all dependent on how much water has gone through the filter; the older the filter gets, the less powerful it becomes. “Over time, contaminants take up more and more space and these filters become less and less effective, and the filter cartridge needs to be replaced,” Evans says. \nEvans notes that the lifespan of a countertop water filter cartridge can vary significantly depending on the brand, model, and filter type. “It's essential to take into account both the initial cost of the filter and how often replacement cartridges are required,” she says. \n“It's reasonable to expect that filter efficacy may decrease over time, highlighting the importance of regular cartridge replacement to maintain optimal water quality.” All of this impacts the overall cost of the device. To look at value, we evaluated the upfront cost of the unit, replacement frequency, and estimated annual filter maintenance cost.\nThe annual cost of maintenance ranged from $62 per year for the\nSans Countertop Water Purifier\nto $150 per year for the\nBluevua Reverse Osmosis Countertop Water Filter\n, which features three filters that are replaced at different times.\nEase of Use and Maintenance\nThe best countertop water filters should be as easy to use in terms of refilling water. We tested several different designs, noting which appliances were too big to fit under the sink and fill directly with faucet water. And for removable water tanks, we noted how easy they were to grip, fill, and pour. \nIf low mobility is a concern, you may want to consider a faucet-fed filter to bypass carrying heavy water tanks. However, for faucet-fed filters, the initial installation can be a pain, and fitting a hose to your kitchen sink may not be ideal. \nRegardless of ergonomics, it’s important to note the specific cleaning instructions for the water reservoir and filtered water tank, as they vary by brand and design. A water filter system’s ease of use is an important indicator of how much use a machine will get.\nCredit:\nBetter Homes & Gardens\nYour Questions, Answered\nWhat are the advantages and disadvantages of countertop water filters?\n“Countertop and dispenser-style filters are generally easy to set up,” Evans says. “They can be more affordable on average compared to more complex systems like\nwhole-house\nor\nunder-sink filters\n. However, they do by nature have a limited capacity and require refilling, they take up space on your counter, and filters have to be maintained and replaced for them to be effective.”\nAnother pain point for some: temperature. While the best countertop water filters save you fridge space, they don’t chill filtered water. Most countertop water filters keep filtered water at room temperature.\nWhat common contaminants do countertop water filters remove?\n“Some are certified to simply reduce contaminants that affect taste and smell, while others can reduce contaminants that impact your health,” McCoy says. “The most common contaminants the countertop water filters can remove are lead, mercury, and chlorine, although this can vary based on the filter you purchase.”\nCan I connect a countertop water filter to multiple faucets?\nIf you’re hoping to use a countertop water filter at home as well as in an RV or another room in your home, double check the installation kit for adapter accessories. “Some water filters can be connected to multiple faucets, but it really will depend on the model you are purchasing,” McCoy says.\nWhat is the healthiest way to filter tap water?\nIs a countertop water filter better than a pitcher or an in-door refrigerator filter? Depends. Are you more likely to remember to change a filter if you see the appliance on display on your counter? According to Evans, “ the effectiveness of any filter relies on consistent and correct usage.”\nWho We Are\nAlice Knisley Matthias\nis a writer who covers kitchen products and appliances for\nBetter Homes & Gardens.\nTo write this article, she consulted insights from our in-house touchless countertop water filter testing and tested one in her home.

My previous water filter took up precious refrigerator space, and I was never quite sure how well it was [purifying my drinking water](https:\/\/www.bhg.com\/water-testing-pitcher-11730674).\n\nCountertop water filters, on the other hand, promised to be a better choice for getting rid of contaminants and microplastics. According to water sommelier [Martin Riese](https:\/\/www.martin-riese.com\/). “A good glass of [drinking water should be odorless](https:\/\/www.bhg.com\/why-does-my-water-smell-8718691), colorless, and will have a refreshing and crisp taste due to the minerals dissolved in the water.”\n\nThere are many different options at various price points, from basic, affordable filters that remove common contaminants like chlorine to reverse-osmosis systems that “filter out many contaminants like lead, PFAS and [microplastics](https:\/\/www.bhg.com\/household-items-releasing-microplastics-11752367),” Riese says.\n\n## Top Picks\nBest Overall:\n\nSALE\n\n[Bluevua Reverse Osmosis Countertop Water Filter at Amazon ~~\\$434~~ \\$299](https:\/\/www.amazon.com\/Bluevua-RO100ROPOT-Countertop-Purification-Filtration\/dp\/B09KRDK677?tag=bhg-onsite-prod-20&ascsubtag=8399087)\n\n[Jump to Review](https:\/\/www.bhg.com\/best-countertop-water-filters-8399087#toc-best-overall-bluevua-ro100ropot-reverse-osmosis-system-countertop-water-filter)\n\nBest Budget:\n\n[Brondell Countertop Water Filtration System at Amazon \\$180](https:\/\/www.amazon.com\/Brondell-Cypress-Countertop-Filter-Certified\/dp\/B00EEDJSES\/?tag=bhg-onsite-prod-20&ascsubtag=8399087)\n\n[Jump to Review](https:\/\/www.bhg.com\/best-countertop-water-filters-8399087#toc-best-budget-brondell-cypress-three-stage-countertop-water-filtration-system)\n\nBest Filter Lifespan:\n\nSALE\n\n[Sans Water Purifier at Livesans.com ~~\\$500~~ \\$400](https:\/\/www.livesans.com\/products\/water-purifier)\n\n[Jump to Review](https:\/\/www.bhg.com\/best-countertop-water-filters-8399087#toc-best-filter-lifespan-sans-water-purifier)\n\nBest For Nitrates:\n\n[AquaTru Countertop Water Filtration System at Amazon \\$465](https:\/\/www.amazon.com\/Countertop-Filtration-Purification-System-Exclusive\/dp\/B01MDLMBKC\/?tag=bhg-onsite-prod-20&ascsubtag=8399087)\n\n[Jump to Review](https:\/\/www.bhg.com\/best-countertop-water-filters-8399087#toc-best-for-nitrates-aquatru-countertop-water-filtration-purification-system)\n\nA Higher-Tech Option We Love:\n\nSALE\n\n[Waterdrop A1 Reverse Osmosis Water Dispenser at Waterdropfilter.com ~~\\$649~~ \\$469](https:\/\/www.waterdropfilter.com\/products\/ro-hot-cold-water-dispenser-a1)\n\n[Jump to Review](https:\/\/www.bhg.com\/best-countertop-water-filters-8399087#toc-a-higher-tech-option-we-love-waterdrop-a1-reverse-osmosis-hotcold-water-dispenser)\n\n### What We Tested\nWe carefully selected the best countertop water filters for every household, taking into consideration **filter lifespan**, **certifications**, **upfront and maintenance costs**, **water capacity**, and **ease of use**.

It’s a plug-and-play system that took me only about 30 minutes to set up, including reading the instructions, washing the pieces, and running the system cycle several times.\n\nThe filter uses five levels of filtration, including a remineralization filter, to deliver purified water into a carafe made of high borosilicate glass. During testing, the filtered water came out consistently clear and clean-tasting, even with frequent cycling thanks to several teenagers and adults constantly filling travel mugs and water bottles.\n\nTo refill, remove the tank from the base, fill it with tap water, and replace it for another cycle. Speed is another plus with the system, as it runs a cycle in a matter of minutes. The display panel gives a clear numerical \"before\" and \"after\" reading on the front of the machine at the start and finish of each cycle.\n\nWe appreciate how easy the water filter system is to use, but there is a decent amount of leftover water from a cycle that is not for consumption. While I used it to water plants and mix [homemade cleaning solutions](https:\/\/www.bhg.com\/homekeeping\/house-cleaning\/cleaning-products-tools\/homemade-cleaners\/), some might find this aspect a bit wasteful.\n\nReplacement filters are \\$50 and one filter should last about a year. I found this to be pretty reasonable, especially compared to the cost of buying bottled water on a regular basis.\n\n**Product Details: Dimensions:** 10.9 x 15.4 x 14.3 in. \\| **Contaminants

Walmart](https:\/\/www.walmart.com\/ip\/H2O-Cypress-Countertop-Water-Filtration-System\/29157368)\n\nWhy You Should Get It\n\n- There is no tank or reservoir to fill or empty, since the system is attached to the kitchen faucet.\n\nKeep in Mind\n\n- The faucet adapter\n\nThe Brondell Countertop Water Filtration System is both more affordable *and* more attractive than other options we tested. It’s minimal, with few controls, and matched our tester’s [modern kitchen decor](https:\/\/www.bhg.com\/industrial-kitchen-ideas-7567247). Plus, it’s compact, so it’s a good option for smaller kitchens.\n\nInstallation is simple—the most complicated part is attaching the faucet adapter to divert water directly from the sink, but even this took us no more than five minutes. All in all, it was about 20 minutes from opening the package to drinking our first glass of filtered water. This included running the water for 10 minutes before using.\n\nThe Brondell uses three stages of filtration, including a composite filter for sediments and a carbon filter to improve water taste and smell and remove VOCs and other contaminants. We noticed that the filtered water had a better overall flavor compared to the unfiltered tap, which usually tastes and smells like chlorine.\n\nDespite the positives, we noticed a few downsides as well. The water feed line that connects to the faucet is exposed, which wasn’t our favorite aesthetically, and though the upfront cost of the device is lower than many, the maintenance cost for buying [replacement filters](https:\/\/www.brondell.com\/cypress-replacement-filters\/) is \\$150 a year.\n\nIt’s also worth noting that the faucet attachment only works with [traditional faucets](https:\/\/www.bhg.com\/types-of-faucets-6830890), not more modern pull-out or [spray faucets](https:\/\/www.bhg.com\/types-of-faucets-8644435). You can, however, purchase a compatible [T-valve](https:\/\/www.brondell.com\/cypress-h630-alternate-installation-t-valve\/) that lets you connect the filter directly to the water supply underneath the sink.\n\n**Product Details: Dimensions:** 10.5 x 3.75 x 13.5 in. \\| **Contaminants Removed:** Heavy metals, chlorine, VOCs \\| **Filtration Process:** Carbon \\| **Certifications Water Quality:** WQA Gold Seal, NSF\/ANSI \\| **Tank Capacity**: NA \\| **Filter Capacity:** 5,000 gal.

We appreciated the sleek, modern design and the ability to heat the water directly using the device instead of transferring it to a kettle or microwave.\n\nThe filter uses a four-stage process, including a UV-C light, to remove contaminants and sediment from tap water. It arrived fully assembled—all we had to do before use was run four cycles with water to flush out the system. The filtered water appeared clearer in appearance, and the taste was slightly different.\n\nMaking hot water with the purifier is super easy; just place a mug on the tray and press the hot water button on the machine. The water takes a few seconds to heat up, but once it does, it’s the perfect temperature for a warm beverage. Green tea had a cleaner, less chemical taste when we prepared it with the purified water.\n\nWe love that the reverse-osmosis filter can last for up to two years (when most filters need to be replaced about once a year), though it’s important to note that the carbon and VOC filters need to be changed approximately every 12 months. A [pack of all three filters](https:\/\/www.livesans.com\/products\/sans-water-purifier-filter-bundle) is available for \\$125, which is fairly cost effective.\n\n**Product Details: Dimensions:** 17\\.3 x 6.7 x 12.2 in. \\| **Contaminants Removed:** Fluoride, heavy metals, PFAS, antibiotics, arsenic, hormones, minerals, microplastics \\| **Filtration Process:** Reverse osmosis \\| **Certifications:** NSF \\| **Tank Capacity:** 0\\.9 gal. \\| **Filter Capacity:** 600 gal. (carbon and VOC filters); 1,200 gal. (reverse-osmosis filter) \\| **Warranty**: Three years\n\n- ![A test water strip before and after using the Sans Water

makes it easy to set up and put replacement filters in the proper slot.\n\nKeep in Mind\n\n- The spout is too low for larger bottles to fit underneath.\n\nThe AquaTru system uses four-stage reverse-osmosis filtration to remove toxins, [heavy metals](https:\/\/www.bhg.com\/signs-you-need-an-iron-filter-11739016), and dissolved solids from your tap water. We were immediately impressed by the easy setup process, which uses color-coding to simplify the installation of the three filtration tanks.\n\nAfter installing the tanks, we ran four cycles (each took 10 to 15 minutes) before drinking the water, per the instructions. The water test strip we used to evaluate our tap water prior to filtration showed a high level of nitrates; when we repeated the water test after filtration, the level had gone down to zero.\n\nWe didn’t notice a big difference in the taste of the water after filtration, but it did seem slightly cleaner. The reservoir holds 3 quarts of filtered water (or about 12 cups); we found ourselves refilling it about every other day, which was not overly burdensome since it only takes a few minutes to filter new water.\n\nThe system was a nice size for our tester’s kitchen, which has plenty of counter space, but it may be too bulky for [small kitchens](https:\/\/www.bhg.com\/kitchen\/small\/our-favorite-small-kitchens-that-live-large\/). Unlike some of our other top picks, it doesn’t include a pitcher—instead, you dispense the water directly into your preferred drinking vessel. It’s worth noting that the spout is too low for larger water bottles to fit underneath.\n\nAs with other multi-stage models, the different filters have different expected lifespans (between six months and two years). You can purchase a [pack of replacement filters](https:\/\/aquatruwater.com\/product\/two-year-classic-combo-filter-pack) designed to last two years for \\$150, which we think is a pretty good value. The manufacturer suggests cleaning the reservoir about once a week.\n\n**Product Details: Dimensions** 14 x 12 x 14 in. \\| **Contaminants Removed:** PFOA, PFOS, lead, fluoride, chlorine, microplastics \\| **Filtration Process:** Reverse osmosis \\| **Certifications:** NSF \\| **Tank Capacity:** 1 gal. \\| **Filter Capacity:** 600 gal.

the Waterdrop A1 Reverse Osmosis Hot Cold Dispenser a reliable choice for large, busy households. The ability to produce both hot and cold water is a plus—we appreciated that we could [make tea](https:\/\/www.bhg.com\/best-iced-tea-makers-7564601) or hot chocolate with water dispensed directly from the machine.\n\nThe test strips that we used during the testing period indicated that the machine, with its seven-stage filtration, effectively removed bacteria. However, the unit is on the larger side compared to others on our list and requires a considerable amount of counter space. We also found the system to be unpleasantly loud during operation.\n\n**Product Details: Dimensions** 18\\.3 x 7.8 x 17.1 in. \\| **Contaminants Removed:** PFOA, PFOS, TDS, fluoride, nitrates, arsenic \\| **Filtration Process:** Reverse osmosis \\| **Certificatio**ns: NSF \\| **Tank Capacity**: 1 gal. \\| **Filter Capacity:** 500 gal.

If you’re on a tighter budget, we love the [Brondell Cypress](https:\/\/www.brondell.com\/cypress-counter-top-water-filter\/)—an effective filtration system that costs less than \\$200.\n\n## Our Testing Process\nTo find the best countertop water filters, we evaluated seven options based on five factors: water smell, water taste, ease of use, design, and the value for cost.\n\nWe first tasted our unfiltered tap water, noting any cloudiness or smell. Then we set up the devices, paying close attention to the instructions. Next we sampled the filtered water, noting changes in appearance or taste.\n\nAt least once during the testing period we used water test strips to compare the unfiltered tap against the filtered water. This helped us see if the filtration process removed contaminants and determine whether the results aligned with the marketing claims.\n\nWe also compared upfront costs with the costs of the replacement filters to help determine a machine’s overall value.\n\n![A person dispenses water from the AquaTru Countertop Water Filtration Purification System into a glass]()\n\n![A person dispenses water from the AquaTru Countertop Water Filtration Purification System into a glass](https:\/\/www.bhg.com\/thmb\/i9QO22tI9TgBV8lm3XdP5SxWqL8=\/4000x0\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-aquatru-countertop-water-filtration-barrett-heald-10-3cb3ee507ab642eab76d2ec0ed1b185a.jpeg)\n\nCredit:\n\nBetter Homes & Gardens\n## What to Know About Countertop Water Filters Before Shopping\n### Freestanding vs. Faucet-fed\nCountertop water filters come in a couple of variations. According to Lowe’s store manager Gary McCoy, “They may be attached directly to a faucet to provide filtered water straight from the tap or come as a standalone dispenser with a reservoir that can be placed anywhere.”\n\n[Faucet-fed filters](https:\/\/www.bhg.com\/best-faucet-water-filters-7495121) mean you don’t have to worry about manually refilling, but they tend to be less renter-friendly, as most manufacturers recommend drilling a hole in your counter to feed the tube from under the sink. This more effectively hides the unsightly water feed line.\n\nIf you’re [short on counter space](https:\/\/www.bhg.com\/kitchen\/small\/small-kitchen-storage-ideas) and don’t have room right by your [kitchen sink](https:\/\/www.bhg.com\/best-kitchen-sinks-7481712), a freestanding countertop water filter is more portable and practical. It’s also great to use on your nightstand if you’d like to have fresh water more easily accessible in the middle of the night.\n\nMost of the best countertop water filters on our list are freestanding, with the [Brondell Cypress](https:\/\/www.amazon.com\/Brondell-Cypress-Countertop-Filter-Certified\/dp\/B00EEDJSES?tag=bhg-onsite-prod-20&ascsubtag=8399087) being the exception. While we enjoyed this feature, we didn’t love the visible water feed line, since we were unwilling to drill a hole through the countertop for the test. Another con is that it’s not compatible with pull-down faucets.\n\n### Dimensions\nMost countertop water filters on our list are between the size of a toaster and a larger coffee maker. In addition to counter space, you need enough clearance above the filter to fill or remove the tank. If you’re placing it underneath low kitchen cabinets, like we did with the [Sans Countertop Water Purifier](https:\/\/www.livesans.com\/products\/water-purifier?variant=44273087873268), the appliance may need to be moved when it’s time to refill.\n\n### Capacity\nThere are two different capacities listed for most countertop water filters—tank capacity and filter capacity. These numbers are easily confused but mean different things. Water tank capacity refers to how much filtered water the appliance can hold. The options on our list range from 0.9 to over 1 gallon.\n\nFilter capacity, on the other hand, indicates roughly how much water the appliance can filter effectively before it needs replacing. If you can’t find a specific number, some manufacturers list the approximate filter lifespan instead. This varies from six months to two years, and differs depending on the type of filter.\n\n### Certifications\nThere are so many contaminants that can show up in tap water, and manufacturers make wildly different claims about what filters can reduce or eliminate. So, what’s the best countertop water filter for removing the most dangerous contaminants? And how do you know if a manufacturer’s claims are legit?\n\n“You can look for National Sanitation Foundation (NSF) certification, which indicates the filter has been independently tested to verify, among other things, that it reduces the contaminants it claims to reduce,” McCoy says. All of the filters on our list have the NSF certification.\n\nAnother common certification is from the American National Standards Institute, or ANSI. You’ll often see NSF or ANSI certifications listed with a specific number. Standards 42, 53, and 401 are considered the industry trifecta for removing tastes and odors (42), traces of medicines and other chemicals (401), and major health concerns (53) such as asbestos, lead, and mercury.\n\nIt’s important to look for these specific numbers if a manufacturer lists an appliance as being NSF certified to understand which contaminants the water filter will actually remove. However, [Sydney Evans](https:\/\/www.ewg.org\/news-insights\/our-experts\/sydney-evans), senior science analyst at the Environmental Working Group, notes that not all filters work on all contaminants.\n\n“Some organizations like NSF and WQA provide some level of third-party verification that the filter actually meets the manufacturer's claims. But it is important to find out exactly what those manufacturer's claims are when shopping for a water filter,” Evans says.\n\n### Filter Lifespan\nLike with a water filter pitcher, the filter components don’t last forever. Most of the countertop water filters we tested estimate that you’ll need to replace the filters every six months to two years. However, many devices have multiple filters that have different requirements depending on the type.\n\nIt’s all dependent on how much water has gone through the filter; the older the filter gets, the less powerful it becomes. “Over time, contaminants take up more and more space and these filters become less and less effective, and the filter cartridge needs to be replaced,” Evans says.\n\nEvans notes that the lifespan of a countertop water filter cartridge can vary significantly depending on the brand, model, and filter type. “It's essential to take into account both the initial cost of the filter and how often replacement cartridges are required,” she says.\n\n“It's reasonable to expect that filter efficacy may decrease over time, highlighting the importance of regular cartridge replacement to maintain optimal water quality.” All of this impacts the overall cost of the device. To look at value, we evaluated the upfront cost of the unit, replacement frequency, and estimated annual filter maintenance cost.\n\nThe annual cost of maintenance ranged from \\$62 per year for the [Sans Countertop Water Purifier](https:\/\/www.livesans.com\/products\/water-purifier?variant=44273087873268) to \\$150 per year for the [Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.amazon.com\/Bluevua-RO100ROPOT-Countertop-Purification-Filtration\/dp\/B09KRDK677?th=1&tag=bhg-onsite-prod-20&ascsubtag=8399087), which features three filters that are replaced at different times.\n\n### Ease of Use and Maintenance\nThe best countertop water filters should be as easy to use in terms of refilling water. We tested several different designs, noting which appliances were too big to fit under the sink and fill directly with faucet water. And for removable water tanks, we noted how easy they were to grip, fill, and pour.\n\nIf low mobility is a concern, you may want to consider a faucet-fed filter to bypass carrying heavy water tanks. However, for faucet-fed filters, the initial installation can be a pain, and fitting a hose to your kitchen sink may not be ideal.\n\nRegardless of ergonomics, it’s important to note the specific cleaning instructions for the water reservoir and filtered water tank, as they vary by brand and design. A water filter system’s ease of use is an important indicator of how much use a machine will get.\n\n![A person presses a button on the Bluevua Reverse Osmosis Countertop Water Filter]()\n\n![A person presses a button on the Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.bhg.com\/thmb\/2Q9CTNDE3E7CcVy3J42r074TacA=\/2842x0\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-11-a4521c93fb9249d9a28cd1fed3fb2238.jpeg)\n\nCredit:\n\nBetter Homes & Gardens\n## Your Questions, Answered\n### What are the advantages and disadvantages of countertop water filters?\n“Countertop and dispenser-style filters are generally easy to set up,” Evans says. “They can be more affordable on average compared to more complex systems like [whole-house](https:\/\/www.bhg.com\/best-whole-house-water-filters-8406113) or [under-sink filters](https:\/\/www.bhg.com\/best-under-sink-water-filters-7378192). However, they do by nature have a limited capacity and require refilling, they take up space on your counter, and filters have to be maintained and replaced for them to be effective.”\n\nAnother pain point for some: temperature. While the best countertop water filters save you fridge space, they don’t chill filtered water. Most countertop water filters keep filtered water at room temperature.\n\n### What common contaminants do countertop water filters remove?\n“Some are certified to simply reduce contaminants that affect taste and smell, while others can reduce contaminants that impact your health,” McCoy says. “The most common contaminants the countertop water filters can remove are lead, mercury, and chlorine, although this can vary based on the filter you purchase.”\n\n### Can I connect a countertop water filter to multiple faucets?\nIf you’re hoping to use a countertop water filter at home as well as in an RV or another room in your home, double check the installation kit for adapter accessories. “Some water filters can be connected to multiple faucets, but it really will depend on the model you are purchasing,” McCoy says.\n\n### What is the healthiest way to filter tap water?\nIs a countertop water filter better than a pitcher or an in-door refrigerator filter? Depends. Are you more likely to remember to change a filter if you see the appliance on display on your counter? According to Evans, “ the effectiveness of any filter relies on consistent and correct usage.”\n\n## Who We Are\n[Alice Knisley Matthias](https:\/\/www.bhg.com\/alice-knisley-matthias-7546613) is a writer who covers kitchen products and appliances for *Better Homes & Gardens.* To write this article, she consulted insights from our in-house touchless countertop water filter testing and tested one in her home.

[filtered water pitcher](https:\/\/www.bhg.com\/how-to-clean-brita-pitcher-8713066) for years, I was eager to try a countertop version instead. My previous water filter took up precious refrigerator space, and I was never quite sure how well it was [purifying my drinking water](https:\/\/www.bhg.com\/water-testing-pitcher-11730674).\n\nCountertop water filters, on the other hand, promised to be a better choice for getting rid of contaminants and microplastics. According to water sommelier [Martin Riese](https:\/\/www.martin-riese.com\/). “A good glass of [drinking water should be odorless](https:\/\/www.bhg.com\/why-does-my-water-smell-8718691), colorless, and will have a refreshing and crisp taste due to the minerals dissolved in the water.”\n\nThere are many different options at various price points, from basic, affordable filters that remove common contaminants like chlorine to reverse-osmosis systems that “filter out many contaminants like lead, PFAS and [microplastics](https:\/\/www.bhg.com\/household-items-releasing-microplastics-11752367),” Riese says.\n\n### What We Tested\nWe carefully selected the best countertop water filters for every household, taking into consideration **filter lifespan**, **certifications**, **upfront and maintenance costs**, **water capacity**, and **ease of use**. For more information on how we tested countertop water filters, check out [our testing process](https:\/\/www.bhg.com\/best-countertop-water-filters-8399087#toc-our-testing-process) below.\n\nWhy You Should Get It\n\n- It’s a plug-and-play option that is easy to use and effective, with fast purification cycles.\n\nKeep in Mind\n\n- The leftover water from each cycle might feel wasteful to some users.\n\nThe Bluevua Reverse Osmosis Countertop Water Filter impressed me with its ease of use and comprehensive filtration, as well as its design. It’s a plug-and-play system that took me only about 30 minutes to set up, including reading the instructions, washing the pieces, and running the system cycle several times.\n\nThe filter uses five levels of filtration, including a remineralization filter, to deliver purified water into a carafe made of high borosilicate glass. During testing, the filtered water came out consistently clear and clean-tasting, even with frequent cycling thanks to several teenagers and adults constantly filling travel mugs and water bottles.\n\nTo refill, remove the tank from the base, fill it with tap water, and replace it for another cycle. Speed is another plus with the system, as it runs a cycle in a matter of minutes. The display panel gives a clear numerical \"before\" and \"after\" reading on the front of the machine at the start and finish of each cycle.\n\nWe appreciate how easy the water filter system is to use, but there is a decent amount of leftover water from a cycle that is not for consumption. While I used it to water plants and mix [homemade cleaning solutions](https:\/\/www.bhg.com\/homekeeping\/house-cleaning\/cleaning-products-tools\/homemade-cleaners\/), some might find this aspect a bit wasteful.\n\nReplacement filters are \\$50 and one filter should last about a year. I found this to be pretty reasonable, especially compared to the cost of buying bottled water on a regular basis.\n\n**Product Details: Dimensions:** 10.9 x 15.4 x 14.3 in. \\| **Contaminants Removed:** Heavy metals, lead, mercury, chlorine, PFOA, PFOS, fluoride ,sulfates \\| **Filtration Process:** Reverse osmosis \\| **Certifications:** WQA, NSF, ANIS\\| **Tank Capacity:** 1\\.05 gal. \\| **Filter Capacity:** 1,050 gal. \\| **Warranty:** One year\n\n- ![Water tests strips before and after using the Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.bhg.com\/thmb\/L4mBcM3NAFeMr44BnecfhsHhucg=\/fit-in\/1500x1000\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-04-comp-9f5b4c2e599744e19347f8ba0b0221ca.jpeg)\n  Credit: Better Homes & Gardens\n- ![A person fills the Bluevua Reverse Osmosis Countertop Water Filter water tank with water](https:\/\/www.bhg.com\/thmb\/pidl_nyLtLDPRqWknGJFAFx5aoM=\/fit-in\/1500x2667\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-07-061b9bf1bbec47149f93e5863bbdb837.jpeg)\n  Credit: Better Homes & Gardens\n- ![A person adds a water tank to the back of the Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.bhg.com\/thmb\/6b2bv8P1NvPEXuhOxHqod5_BK_Y=\/fit-in\/1500x2155\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-12-eff9211ae6954bd9b18effbe62fa09c8.jpeg)\n  Credit: Better Homes & Gardens\n- ![The Bluevua Reverse Osmosis Countertop Water Filter while in use](https:\/\/www.bhg.com\/thmb\/79LzlaTjiWTxyo1bfH9Avoykvg0=\/fit-in\/1500x2667\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-09-a17e376d52aa4e1484c71120fe8f9c7a.jpeg)\n  Credit: Better Homes & Gardens\n- ![The digital display on the Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.bhg.com\/thmb\/_Qjen41c_jPHn-0aTGyFba3GA_M=\/fit-in\/1500x2040\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-watwr-filter-alice-knisley-matthias-10-8ecdf7debdba4688ab6a28abc904833b.jpeg)\n  Credit: Better Homes & Gardens\n\n- ![Water tests strips before and after using the Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.bhg.com\/thmb\/aPpmPSiku4yHn0woWDZhB6v78-0=\/fit-in\/200x1000\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-04-comp-9f5b4c2e599744e19347f8ba0b0221ca.jpeg)\n- ![A person fills the Bluevua Reverse Osmosis Countertop Water Filter water tank with water](https:\/\/www.bhg.com\/thmb\/T0cEgminax5zT2iYAvo-E4MZY4I=\/fit-in\/200x2667\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-07-061b9bf1bbec47149f93e5863bbdb837.jpeg)\n- ![A person adds a water tank to the back of the Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.bhg.com\/thmb\/BIyTePfb3tneYDgE2nI63GRsSzc=\/fit-in\/200x2155\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-12-eff9211ae6954bd9b18effbe62fa09c8.jpeg)\n- ![The Bluevua Reverse Osmosis Countertop Water Filter while in use](https:\/\/www.bhg.com\/thmb\/dO_IpZBZFIQhrsJvzj-KoUtc8fM=\/fit-in\/200x2667\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-09-a17e376d52aa4e1484c71120fe8f9c7a.jpeg)\n- ![The digital display on the Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.bhg.com\/thmb\/-S-MxfRsK9G6q6utejoWPkSDUIo=\/fit-in\/200x2040\/filters:no_upscale\$\$:strip_icc\$\$\/bhg-bluevua-reverse-osmosis-countertop-watwr-filter-alice-knisley-matthias-10-8ecdf7debdba4688ab6a28abc904833b.jpeg)\n\nWhy You Should Get It\n\n- There is no tank or reservoir to fill or empty, since the system is attached to the kitchen faucet.\n\nKeep in Mind\n\n- The faucet adapter\n\nThe Brondell Countertop Water Filtration System is both more affordable *and* more attractive than other options we tested. It’s minimal, with few controls, and matched our tester’s [modern kitchen decor](https:\/\/www.bhg.com\/industrial-kitchen-ideas-7567247). Plus, it’s compact, so it’s a good option for smaller kitchens.\n\nInstallation is simple—the most complicated part is attaching the faucet adapter to divert water directly from the sink, but even this took us no more than five minutes. All in all, it was about 20 minutes from opening the package to drinking our first glass of filtered water. This included running the water for 10 minutes before using.\n\nThe Brondell uses three stages of filtration, including a composite filter for sediments and a carbon filter to improve water taste and smell and remove VOCs and other contaminants. We noticed that the filtered water had a better overall flavor compared to the unfiltered tap, which usually tastes and smells like chlorine.\n\nDespite the positives, we noticed a few downsides as well. The water feed line that connects to the faucet is exposed, which wasn’t our favorite aesthetically, and though the upfront cost of the device is lower than many, the maintenance cost for buying [replacement filters](https:\/\/www.brondell.com\/cypress-replacement-filters\/) is \\$150 a year.\n\nIt’s also worth noting that the faucet attachment only works with [traditional faucets](https:\/\/www.bhg.com\/types-of-faucets-6830890), not more modern pull-out or [spray faucets](https:\/\/www.bhg.com\/types-of-faucets-8644435).

We appreciated the sleek, modern design and the ability to heat the water directly using the device instead of transferring it to a kettle or microwave.\n\nThe filter uses a four-stage process, including a UV-C light, to remove contaminants and sediment from tap water. It arrived fully assembled—all we had to do before use was run four cycles with water to flush out the system. The filtered water appeared clearer in appearance, and the taste was slightly different.\n\nMaking hot water with the purifier is super easy; just place a mug on the tray and press the hot water button on the machine. The water takes a few seconds to heat up, but once it does, it’s the perfect temperature for a warm beverage. Green tea had a cleaner, less chemical taste when we prepared it with the purified water.\n\nWe love that the reverse-osmosis filter can last for up to two years (when most filters need to be replaced about once a year), though it’s important to note that the carbon and VOC filters need to be changed approximately every 12 months. A [pack of all three filters](https:\/\/www.livesans.com\/products\/sans-water-purifier-filter-bundle) is available for \\$125, which is fairly cost effective.\n\n**Product Details: Dimensions:** 17\\.3 x 6.7 x 12.2 in. \\| **Contaminants Removed:** Fluoride, heavy metals, PFAS, antibiotics, arsenic, hormones, minerals, microplastics \\| **Filtration Process:** Reverse osmosis \\| **Certifications:** NSF \\| **Tank Capacity:** 0\\.9 gal. \\| **Filter Capacity:** 600 gal. (carbon and VOC filters); 1,200 gal.

We were immediately impressed by the easy setup process, which uses color-coding to simplify the installation of the three filtration tanks.\n\nAfter installing the tanks, we ran four cycles (each took 10 to 15 minutes) before drinking the water, per the instructions. The water test strip we used to evaluate our tap water prior to filtration showed a high level of nitrates; when we repeated the water test after filtration, the level had gone down to zero.\n\nWe didn’t notice a big difference in the taste of the water after filtration, but it did seem slightly cleaner. The reservoir holds 3 quarts of filtered water (or about 12 cups); we found ourselves refilling it about every other day, which was not overly burdensome since it only takes a few minutes to filter new water.\n\nThe system was a nice size for our tester’s kitchen, which has plenty of counter space, but it may be too bulky for [small kitchens](https:\/\/www.bhg.com\/kitchen\/small\/our-favorite-small-kitchens-that-live-large\/). Unlike some of our other top picks, it doesn’t include a pitcher—instead, you dispense the water directly into your preferred drinking vessel. It’s worth noting that the spout is too low for larger water bottles to fit underneath.\n\nAs with other multi-stage models, the different filters have different expected lifespans (between six months and two years). You can purchase a [pack of replacement filters](https:\/\/aquatruwater.com\/product\/two-year-classic-combo-filter-pack) designed to last two years for \\$150, which we think is a pretty good value. The manufacturer suggests cleaning the reservoir about once a week.\n\n**Product Details: Dimensions** 14 x 12 x 14 in. \\| **Contaminants Removed:** PFOA, PFOS, lead, fluoride, chlorine, microplastics \\| **Filtration Process:** Reverse osmosis \\| **Certifications:** NSF \\| **Tank Capacity:** 1 gal. \\| **Filter Capacity:** 600 gal.

The ability to produce both hot and cold water is a plus—we appreciated that we could [make tea](https:\/\/www.bhg.com\/best-iced-tea-makers-7564601) or hot chocolate with water dispensed directly from the machine.\n\nThe test strips that we used during the testing period indicated that the machine, with its seven-stage filtration, effectively removed bacteria. However, the unit is on the larger side compared to others on our list and requires a considerable amount of counter space. We also found the system to be unpleasantly loud during operation.\n\n**Product Details: Dimensions** 18\\.3 x 7.8 x 17.1 in. \\| **Contaminants Removed:** PFOA, PFOS, TDS, fluoride, nitrates, arsenic \\| **Filtration Process:** Reverse osmosis \\| **Certificatio**ns: NSF \\| **Tank Capacity**: 1 gal. \\| **Filter Capacity:** 500 gal.

If you’re on a tighter budget, we love the [Brondell Cypress](https:\/\/www.brondell.com\/cypress-counter-top-water-filter\/)—an effective filtration system that costs less than \\$200.\n\n## Our Testing Process\nTo find the best countertop water filters, we evaluated seven options based on five factors: water smell, water taste, ease of use, design, and the value for cost.\n\nWe first tasted our unfiltered tap water, noting any cloudiness or smell. Then we set up the devices, paying close attention to the instructions. Next we sampled the filtered water, noting changes in appearance or taste.\n\nAt least once during the testing period we used water test strips to compare the unfiltered tap against the filtered water. This helped us see if the filtration process removed contaminants and determine whether the results aligned with the marketing claims.\n\nWe also compared upfront costs with the costs of the replacement filters to help determine a machine’s overall value.\n\nCredit:\n\nBetter Homes & Gardens\n## What to Know About Countertop Water Filters Before Shopping\n### Freestanding vs. Faucet-fed\nCountertop water filters come in a couple of variations. According to Lowe’s store manager Gary McCoy, “They may be attached directly to a faucet to provide filtered water straight from the tap or come as a standalone dispenser with a reservoir that can be placed anywhere.”\n\n[Faucet-fed filters](https:\/\/www.bhg.com\/best-faucet-water-filters-7495121) mean you don’t have to worry about manually refilling, but they tend to be less renter-friendly, as most manufacturers recommend drilling a hole in your counter to feed the tube from under the sink. This more effectively hides the unsightly water feed line.\n\nIf you’re [short on counter space](https:\/\/www.bhg.com\/kitchen\/small\/small-kitchen-storage-ideas) and don’t have room right by your [kitchen sink](https:\/\/www.bhg.com\/best-kitchen-sinks-7481712), a freestanding countertop water filter is more portable and practical. It’s also great to use on your nightstand if you’d like to have fresh water more easily accessible in the middle of the night.\n\nMost of the best countertop water filters on our list are freestanding, with the [Brondell Cypress](https:\/\/www.amazon.com\/Brondell-Cypress-Countertop-Filter-Certified\/dp\/B00EEDJSES?tag=bhg-onsite-prod-20&ascsubtag=8399087) being the exception. While we enjoyed this feature, we didn’t love the visible water feed line, since we were unwilling to drill a hole through the countertop for the test. Another con is that it’s not compatible with pull-down faucets.\n\n### Dimensions\nMost countertop water filters on our list are between the size of a toaster and a larger coffee maker. In addition to counter space, you need enough clearance above the filter to fill or remove the tank. If you’re placing it underneath low kitchen cabinets, like we did with the [Sans Countertop Water Purifier](https:\/\/www.livesans.com\/products\/water-purifier?variant=44273087873268), the appliance may need to be moved when it’s time to refill.\n\n### Capacity\nThere are two different capacities listed for most countertop water filters—tank capacity and filter capacity. These numbers are easily confused but mean different things. Water tank capacity refers to how much filtered water the appliance can hold. The options on our list range from 0.9 to over 1 gallon.\n\nFilter capacity, on the other hand, indicates roughly how much water the appliance can filter effectively before it needs replacing. If you can’t find a specific number, some manufacturers list the approximate filter lifespan instead. This varies from six months to two years, and differs depending on the type of filter.\n\n### Certifications\nThere are so many contaminants that can show up in tap water, and manufacturers make wildly different claims about what filters can reduce or eliminate. So, what’s the best countertop water filter for removing the most dangerous contaminants? And how do you know if a manufacturer’s claims are legit?\n\n“You can look for National Sanitation Foundation (NSF) certification, which indicates the filter has been independently tested to verify, among other things, that it reduces the contaminants it claims to reduce,” McCoy says. All of the filters on our list have the NSF certification.\n\nAnother common certification is from the American National Standards Institute, or ANSI. You’ll often see NSF or ANSI certifications listed with a specific number. Standards 42, 53, and 401 are considered the industry trifecta for removing tastes and odors (42), traces of medicines and other chemicals (401), and major health concerns (53) such as asbestos, lead, and mercury.\n\nIt’s important to look for these specific numbers if a manufacturer lists an appliance as being NSF certified to understand which contaminants the water filter will actually remove. However, [Sydney Evans](https:\/\/www.ewg.org\/news-insights\/our-experts\/sydney-evans), senior science analyst at the Environmental Working Group, notes that not all filters work on all contaminants.\n\n“Some organizations like NSF and WQA provide some level of third-party verification that the filter actually meets the manufacturer's claims. But it is important to find out exactly what those manufacturer's claims are when shopping for a water filter,” Evans says.\n\n### Filter Lifespan\nLike with a water filter pitcher, the filter components don’t last forever. Most of the countertop water filters we tested estimate that you’ll need to replace the filters every six months to two years. However, many devices have multiple filters that have different requirements depending on the type.\n\nIt’s all dependent on how much water has gone through the filter; the older the filter gets, the less powerful it becomes. “Over time, contaminants take up more and more space and these filters become less and less effective, and the filter cartridge needs to be replaced,” Evans says.\n\nEvans notes that the lifespan of a countertop water filter cartridge can vary significantly depending on the brand, model, and filter type. “It's essential to take into account both the initial cost of the filter and how often replacement cartridges are required,” she says.\n\n“It's reasonable to expect that filter efficacy may decrease over time, highlighting the importance of regular cartridge replacement to maintain optimal water quality.” All of this impacts the overall cost of the device. To look at value, we evaluated the upfront cost of the unit, replacement frequency, and estimated annual filter maintenance cost.\n\nThe annual cost of maintenance ranged from \\$62 per year for the [Sans Countertop Water Purifier](https:\/\/www.livesans.com\/products\/water-purifier?variant=44273087873268) to \\$150 per year for the [Bluevua Reverse Osmosis Countertop Water Filter](https:\/\/www.amazon.com\/Bluevua-RO100ROPOT-Countertop-Purification-Filtration\/dp\/B09KRDK677?th=1&tag=bhg-onsite-prod-20&ascsubtag=8399087), which features three filters that are replaced at different times.\n\n### Ease of Use and Maintenance\nThe best countertop water filters should be as easy to use in terms of refilling water. We tested several different designs, noting which appliances were too big to fit under the sink and fill directly with faucet water. And for removable water tanks, we noted how easy they were to grip, fill, and pour.\n\nIf low mobility is a concern, you may want to consider a faucet-fed filter to bypass carrying heavy water tanks. However, for faucet-fed filters, the initial installation can be a pain, and fitting a hose to your kitchen sink may not be ideal.\n\nRegardless of ergonomics, it’s important to note the specific cleaning instructions for the water reservoir and filtered water tank, as they vary by brand and design. A water filter system’s ease of use is an important indicator of how much use a machine will get.\n\nCredit:\n\nBetter Homes & Gardens\n## Your Questions, Answered\n### What are the advantages and disadvantages of countertop water filters?\n“Countertop and dispenser-style filters are generally easy to set up,” Evans says. “They can be more affordable on average compared to more complex systems like [whole-house](https:\/\/www.bhg.com\/best-whole-house-water-filters-8406113) or [under-sink filters](https:\/\/www.bhg.com\/best-under-sink-water-filters-7378192). However, they do by nature have a limited capacity and require refilling, they take up space on your counter, and filters have to be maintained and replaced for them to be effective.”\n\nAnother pain point for some: temperature. While the best countertop water filters save you fridge space, they don’t chill filtered water. Most countertop water filters keep filtered water at room temperature.\n\n### What common contaminants do countertop water filters remove?\n“Some are certified to simply reduce contaminants that affect taste and smell, while others can reduce contaminants that impact your health,” McCoy says. “The most common contaminants the countertop water filters can remove are lead, mercury, and chlorine, although this can vary based on the filter you purchase.”\n\n### Can I connect a countertop water filter to multiple faucets?\nIf you’re hoping to use a countertop water filter at home as well as in an RV or another room in your home, double check the installation kit for adapter accessories. “Some water filters can be connected to multiple faucets, but it really will depend on the model you are purchasing,” McCoy says.\n\n### What is the healthiest way to filter tap water?\nIs a countertop water filter better than a pitcher or an in-door refrigerator filter? Depends. Are you more likely to remember to change a filter if you see the appliance on display on your counter? According to Evans, “ the effectiveness of any filter relies on consistent and correct usage.”\n\n## Who We Are\n[Alice Knisley Matthias](https:\/\/www.bhg.com\/alice-knisley-matthias-7546613) is a writer who covers kitchen products and appliances for *Better Homes & Gardens.* To write this article, she consulted insights from our in-house touchless countertop water filter testing and tested one in her home.

Boilerpipe Text

Having relied on a refrigerated filtered water pitcher for years, I was eager to try a countertop version instead. My previous water filter took up precious refrigerator space, and I was never quite sure how well it was purifying my drinking water . Countertop water filters, on the other hand, promised to be a better choice for getting rid of contaminants and microplastics. According to water sommelier Martin Riese . “A good glass of drinking water should be odorless , colorless, and will have a refreshing and crisp taste due to the minerals dissolved in the water.” There are many different options at various price points, from basic, affordable filters that remove common contaminants like chlorine to reverse-osmosis systems that “filter out many contaminants like lead, PFAS and microplastics ,” Riese says. What We Tested We carefully selected the best countertop water filters for every household, taking into consideration filter lifespan , certifications , upfront and maintenance costs , water capacity , and ease of use . For more information on how we tested countertop water filters, check out our testing process below. Why You Should Get It It’s a plug-and-play option that is easy to use and effective, with fast purification cycles. Keep in Mind The leftover water from each cycle might feel wasteful to some users. The Bluevua Reverse Osmosis Countertop Water Filter impressed me with its ease of use and comprehensive filtration, as well as its design. It’s a plug-and-play system that took me only about 30 minutes to set up, including reading the instructions, washing the pieces, and running the system cycle several times. The filter uses five levels of filtration, including a remineralization filter, to deliver purified water into a carafe made of high borosilicate glass. During testing, the filtered water came out consistently clear and clean-tasting, even with frequent cycling thanks to several teenagers and adults constantly filling travel mugs and water bottles. To refill, remove the tank from the base, fill it with tap water, and replace it for another cycle. Speed is another plus with the system, as it runs a cycle in a matter of minutes. The display panel gives a clear numerical "before" and "after" reading on the front of the machine at the start and finish of each cycle. We appreciate how easy the water filter system is to use, but there is a decent amount of leftover water from a cycle that is not for consumption. While I used it to water plants and mix homemade cleaning solutions , some might find this aspect a bit wasteful. Replacement filters are $50 and one filter should last about a year. I found this to be pretty reasonable, especially compared to the cost of buying bottled water on a regular basis. Product Details: Dimensions: 10.9 x 15.4 x 14.3 in. | Contaminants Removed: Heavy metals, lead, mercury, chlorine, PFOA, PFOS, fluoride ,sulfates | Filtration Process: Reverse osmosis | Certifications: WQA, NSF, ANIS | Tank Capacity: 1.05 gal. | Filter Capacity: 1,050 gal. | Warranty: One year Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Why You Should Get It There is no tank or reservoir to fill or empty, since the system is attached to the kitchen faucet. Keep in Mind The faucet adapter The Brondell Countertop Water Filtration System is both more affordable and more attractive than other options we tested. It’s minimal, with few controls, and matched our tester’s modern kitchen decor . Plus, it’s compact, so it’s a good option for smaller kitchens. Installation is simple—the most complicated part is attaching the faucet adapter to divert water directly from the sink, but even this took us no more than five minutes. All in all, it was about 20 minutes from opening the package to drinking our first glass of filtered water. This included running the water for 10 minutes before using. The Brondell uses three stages of filtration, including a composite filter for sediments and a carbon filter to improve water taste and smell and remove VOCs and other contaminants. We noticed that the filtered water had a better overall flavor compared to the unfiltered tap, which usually tastes and smells like chlorine. Despite the positives, we noticed a few downsides as well. The water feed line that connects to the faucet is exposed, which wasn’t our favorite aesthetically, and though the upfront cost of the device is lower than many, the maintenance cost for buying replacement filters is $150 a year. It’s also worth noting that the faucet attachment only works with traditional faucets , not more modern pull-out or spray faucets . You can, however, purchase a compatible T-valve that lets you connect the filter directly to the water supply underneath the sink. Product Details: Dimensions: 10.5 x 3.75 x 13.5 in. | Contaminants Removed: Heavy metals, chlorine, VOCs | Filtration Process: Carbon | Certifications Water Quality: WQA Gold Seal, NSF/ANSI | Tank Capacity : NA | Filter Capacity: 5,000 gal. (aesthetic chlorine); 150 gal. (VOCs) | Warranty: One year Credit: Better Homes & Gardens We connected the filter with an adapter valve. Credit: Better Homes & Gardens Despite a more involved setup, it took only about 30 minutes to assemble. Credit: Better Homes & Gardens Because it connects through the faucet, the Brondell Cypress is limited when it comes to placement. Credit: Better Homes & Gardens Why You Should Get It The reverse-osmosis filters can last for up to two years with proper maintenance, cutting down on recurring costs. Keep in Mind The carbon and VOC filters need to be replaced more often. If you are looking for a low maintenance countertop water filter with long-lasting filters, the Sans Countertop Water Purifier is a great choice. We appreciated the sleek, modern design and the ability to heat the water directly using the device instead of transferring it to a kettle or microwave. The filter uses a four-stage process, including a UV-C light, to remove contaminants and sediment from tap water. It arrived fully assembled—all we had to do before use was run four cycles with water to flush out the system. The filtered water appeared clearer in appearance, and the taste was slightly different. Making hot water with the purifier is super easy; just place a mug on the tray and press the hot water button on the machine. The water takes a few seconds to heat up, but once it does, it’s the perfect temperature for a warm beverage. Green tea had a cleaner, less chemical taste when we prepared it with the purified water. We love that the reverse-osmosis filter can last for up to two years (when most filters need to be replaced about once a year), though it’s important to note that the carbon and VOC filters need to be changed approximately every 12 months. A pack of all three filters is available for $125, which is fairly cost effective. Product Details: Dimensions: 17.3 x 6.7 x 12.2 in. | Contaminants Removed: Fluoride, heavy metals, PFAS, antibiotics, arsenic, hormones, minerals, microplastics | Filtration Process: Reverse osmosis | Certifications: NSF | Tank Capacity: 0.9 gal. | Filter Capacity: 600 gal. (carbon and VOC filters); 1,200 gal. (reverse-osmosis filter) | Warranty : Three years Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Why You Should Get It A color-coded system makes it easy to set up and put replacement filters in the proper slot. Keep in Mind The spout is too low for larger bottles to fit underneath. The AquaTru system uses four-stage reverse-osmosis filtration to remove toxins, heavy metals , and dissolved solids from your tap water. We were immediately impressed by the easy setup process, which uses color-coding to simplify the installation of the three filtration tanks. After installing the tanks, we ran four cycles (each took 10 to 15 minutes) before drinking the water, per the instructions. The water test strip we used to evaluate our tap water prior to filtration showed a high level of nitrates; when we repeated the water test after filtration, the level had gone down to zero. We didn’t notice a big difference in the taste of the water after filtration, but it did seem slightly cleaner. The reservoir holds 3 quarts of filtered water (or about 12 cups); we found ourselves refilling it about every other day, which was not overly burdensome since it only takes a few minutes to filter new water. The system was a nice size for our tester’s kitchen, which has plenty of counter space, but it may be too bulky for small kitchens . Unlike some of our other top picks, it doesn’t include a pitcher—instead, you dispense the water directly into your preferred drinking vessel. It’s worth noting that the spout is too low for larger water bottles to fit underneath. As with other multi-stage models, the different filters have different expected lifespans (between six months and two years). You can purchase a pack of replacement filters designed to last two years for $150, which we think is a pretty good value. The manufacturer suggests cleaning the reservoir about once a week. Product Details: Dimensions 14 x 12 x 14 in. | Contaminants Removed: PFOA, PFOS, lead, fluoride, chlorine, microplastics | Filtration Process: Reverse osmosis | Certifications: NSF | Tank Capacity: 1 gal. | Filter Capacity: 600 gal. (pre-filter); 1,200 gal. (reverse osmosis) | Warranty: One year Credit: Better Homes & Gardens Credit: Better Homes & Gardens The dispenser is lower than on other models, so you'll need to hold taller cups or pitchers while filling. Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Why You Should Get It The advanced seven-stage filtration effectively removed bacteria during testing. Keep in Mind The machine is large and unpleasantly loud when operating. A simple set-up and solid build with touchscreen control make the Waterdrop A1 Reverse Osmosis Hot Cold Dispenser a reliable choice for large, busy households. The ability to produce both hot and cold water is a plus—we appreciated that we could make tea or hot chocolate with water dispensed directly from the machine. The test strips that we used during the testing period indicated that the machine, with its seven-stage filtration, effectively removed bacteria. However, the unit is on the larger side compared to others on our list and requires a considerable amount of counter space. We also found the system to be unpleasantly loud during operation.

(CF filter); 1,000 gal. (reverse osmosis) | Warranty: One year Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens Credit: Better Homes & Gardens The Bottom Line For fast filtration, great-tasting water, and simple setup, the Bluevua Reverse Osmosis Countertop Water Filter stands out as our top choice for the best countertop water filter. If you’re on a tighter budget, we love the Brondell Cypress —an effective filtration system that costs less than $200. Our Testing Process To find the best countertop water filters, we evaluated seven options based on five factors: water smell, water taste, ease of use, design, and the value for cost. We first tasted our unfiltered tap water, noting any cloudiness or smell. Then we set up the devices, paying close attention to the instructions. Next we sampled the filtered water, noting changes in appearance or taste. At least once during the testing period we used water test strips to compare the unfiltered tap against the filtered water. This helped us see if the filtration process removed contaminants and determine whether the results aligned with the marketing claims. We also compared upfront costs with the costs of the replacement filters to help determine a machine’s overall value. Credit: Better Homes & Gardens What to Know About Countertop Water Filters Before Shopping Freestanding vs. Faucet-fed Countertop water filters come in a couple of variations. According to Lowe’s store manager Gary McCoy, “They may be attached directly to a faucet to provide filtered water straight from the tap or come as a standalone dispenser with a reservoir that can be placed anywhere.” Faucet-fed filters mean you don’t have to worry about manually refilling, but they tend to be less renter-friendly, as most manufacturers recommend drilling a hole in your counter to feed the tube from under the sink. This more effectively hides the unsightly water feed line. If you’re short on counter space and don’t have room right by your kitchen sink , a freestanding countertop water filter is more portable and practical. It’s also great to use on your nightstand if you’d like to have fresh water more easily accessible in the middle of the night. Most of the best countertop water filters on our list are freestanding, with the Brondell Cypress being the exception. While we enjoyed this feature, we didn’t love the visible water feed line, since we were unwilling to drill a hole through the countertop for the test. Another con is that it’s not compatible with pull-down faucets. Dimensions Most countertop water filters on our list are between the size of a toaster and a larger coffee maker. In addition to counter space, you need enough clearance above the filter to fill or remove the tank. If you’re placing it underneath low kitchen cabinets, like we did with the Sans Countertop Water Purifier , the appliance may need to be moved when it’s time to refill. Capacity There are two different capacities listed for most countertop water filters—tank capacity and filter capacity. These numbers are easily confused but mean different things. Water tank capacity refers to how much filtered water the appliance can hold. The options on our list range from 0.9 to over 1 gallon. Filter capacity, on the other hand, indicates roughly how much water the appliance can filter effectively before it needs replacing.

Certifications There are so many contaminants that can show up in tap water, and manufacturers make wildly different claims about what filters can reduce or eliminate. So, what’s the best countertop water filter for removing the most dangerous contaminants? And how do you know if a manufacturer’s claims are legit? “You can look for National Sanitation Foundation (NSF) certification, which indicates the filter has been independently tested to verify, among other things, that it reduces the contaminants it claims to reduce,” McCoy says. All of the filters on our list have the NSF certification. Another common certification is from the American National Standards Institute, or ANSI. You’ll often see NSF or ANSI certifications listed with a specific number. Standards 42, 53, and 401 are considered the industry trifecta for removing tastes and odors (42), traces of medicines and other chemicals (401), and major health concerns (53) such as asbestos, lead, and mercury. It’s important to look for these specific numbers if a manufacturer lists an appliance as being NSF certified to understand which contaminants the water filter will actually remove. However, Sydney Evans , senior science analyst at the Environmental Working Group, notes that not all filters work on all contaminants. “Some organizations like NSF and WQA provide some level of third-party verification that the filter actually meets the manufacturer's claims.

The annual cost of maintenance ranged from $62 per year for the Sans Countertop Water Purifier to $150 per year for the Bluevua Reverse Osmosis Countertop Water Filter , which features three filters that are replaced at different times. Ease of Use and Maintenance The best countertop water filters should be as easy to use in terms of refilling water. We tested several different designs, noting which appliances were too big to fit under the sink and fill directly with faucet water. And for removable water tanks, we noted how easy they were to grip, fill, and pour. If low mobility is a concern, you may want to consider a faucet-fed filter to bypass carrying heavy water tanks. However, for faucet-fed filters, the initial installation can be a pain, and fitting a hose to your kitchen sink may not be ideal.

My previous water filter took up precious refrigerator space, and I was never quite sure how well it was [purifying my drinking water](https://www.bhg.com/water-testing-pitcher-11730674). Countertop water filters, on the other hand, promised to be a better choice for getting rid of contaminants and microplastics. According to water sommelier [Martin Riese](https://www.martin-riese.com/). “A good glass of [drinking water should be odorless](https://www.bhg.com/why-does-my-water-smell-8718691), colorless, and will have a refreshing and crisp taste due to the minerals dissolved in the water.” There are many different options at various price points, from basic, affordable filters that remove common contaminants like chlorine to reverse-osmosis systems that “filter out many contaminants like lead, PFAS and [microplastics](https://www.bhg.com/household-items-releasing-microplastics-11752367),” Riese says. ## Top Picks Best Overall: SALE [Bluevua Reverse Osmosis Countertop Water Filter at Amazon ~~\$434~~ \$299](https://www.amazon.com/Bluevua-RO100ROPOT-Countertop-Purification-Filtration/dp/B09KRDK677?tag=bhg-onsite-prod-20&ascsubtag=8399087) [Jump to Review](https://www.bhg.com/best-countertop-water-filters-8399087#toc-best-overall-bluevua-ro100ropot-reverse-osmosis-system-countertop-water-filter) Best Budget: [Brondell Countertop Water Filtration System at Amazon \$180](https://www.amazon.com/Brondell-Cypress-Countertop-Filter-Certified/dp/B00EEDJSES/?tag=bhg-onsite-prod-20&ascsubtag=8399087) [Jump to Review](https://www.bhg.com/best-countertop-water-filters-8399087#toc-best-budget-brondell-cypress-three-stage-countertop-water-filtration-system) Best Filter Lifespan: SALE [Sans Water Purifier at Livesans.com ~~\$500~~ \$400](https://www.livesans.com/products/water-purifier) [Jump to Review](https://www.bhg.com/best-countertop-water-filters-8399087#toc-best-filter-lifespan-sans-water-purifier) Best For Nitrates: [AquaTru Countertop Water Filtration System at Amazon \$465](https://www.amazon.com/Countertop-Filtration-Purification-System-Exclusive/dp/B01MDLMBKC/?tag=bhg-onsite-prod-20&ascsubtag=8399087) [Jump to Review](https://www.bhg.com/best-countertop-water-filters-8399087#toc-best-for-nitrates-aquatru-countertop-water-filtration-purification-system) A Higher-Tech Option We Love: SALE [Waterdrop A1 Reverse Osmosis Water Dispenser at Waterdropfilter.com ~~\$649~~ \$469](https://www.waterdropfilter.com/products/ro-hot-cold-water-dispenser-a1) [Jump to Review](https://www.bhg.com/best-countertop-water-filters-8399087#toc-a-higher-tech-option-we-love-waterdrop-a1-reverse-osmosis-hotcold-water-dispenser) ### What We Tested We carefully selected the best countertop water filters for every household, taking into consideration **filter lifespan**, **certifications**, **upfront and maintenance costs**, **water capacity**, and **ease of use**.

Keep in Mind - The leftover water from each cycle might feel wasteful to some users. The Bluevua Reverse Osmosis Countertop Water Filter impressed me with its ease of use and comprehensive filtration, as well as its design. It’s a plug-and-play system that took me only about 30 minutes to set up, including reading the instructions, washing the pieces, and running the system cycle several times. The filter uses five levels of filtration, including a remineralization filter, to deliver purified water into a carafe made of high borosilicate glass. During testing, the filtered water came out consistently clear and clean-tasting, even with frequent cycling thanks to several teenagers and adults constantly filling travel mugs and water bottles. To refill, remove the tank from the base, fill it with tap water, and replace it for another cycle. Speed is another plus with the system, as it runs a cycle in a matter of minutes. The display panel gives a clear numerical "before" and "after" reading on the front of the machine at the start and finish of each cycle. We appreciate how easy the water filter system is to use, but there is a decent amount of leftover water from a cycle that is not for consumption. While I used it to water plants and mix [homemade cleaning solutions](https://www.bhg.com/homekeeping/house-cleaning/cleaning-products-tools/homemade-cleaners/), some might find this aspect a bit wasteful. Replacement filters are \$50 and one filter should last about a year. I found this to be pretty reasonable, especially compared to the cost of buying bottled water on a regular basis. **Product Details: Dimensions:** 10.9 x 15.4 x 14.3 in. \| **Contaminants Removed:** Heavy metals, lead, mercury, chlorine, PFOA, PFOS, fluoride ,sulfates \| **Filtration Process:** Reverse osmosis \| **Certifications:** WQA, NSF, ANIS\| **Tank Capacity:** 1\.05 gal. \| **Filter Capacity:** 1,050 gal. \| **Warranty:** One year -

There is no tank or reservoir to fill or empty, since the system is attached to the kitchen faucet. Keep in Mind - The faucet adapter The Brondell Countertop Water Filtration System is both more affordable *and* more attractive than other options we tested. It’s minimal, with few controls, and matched our tester’s [modern kitchen decor](https://www.bhg.com/industrial-kitchen-ideas-7567247). Plus, it’s compact, so it’s a good option for smaller kitchens. Installation is simple—the most complicated part is attaching the faucet adapter to divert water directly from the sink, but even this took us no more than five minutes. All in all, it was about 20 minutes from opening the package to drinking our first glass of filtered water. This included running the water for 10 minutes before using. The Brondell uses three stages of filtration, including a composite filter for sediments and a carbon filter to improve water taste and smell and remove VOCs and other contaminants. We noticed that the filtered water had a better overall flavor compared to the unfiltered tap, which usually tastes and smells like chlorine. Despite the positives, we noticed a few downsides as well. The water feed line that connects to the faucet is exposed, which wasn’t our favorite aesthetically, and though the upfront cost of the device is lower than many, the maintenance cost for buying [replacement filters](https://www.brondell.com/cypress-replacement-filters/) is \$150 a year. It’s also worth noting that the faucet attachment only works with [traditional faucets](https://www.bhg.com/types-of-faucets-6830890), not more modern pull-out or [spray faucets](https://www.bhg.com/types-of-faucets-8644435). You can, however, purchase a compatible [T-valve](https://www.brondell.com/cypress-h630-alternate-installation-t-valve/) that lets you connect the filter directly to the water supply underneath the sink. **Product Details: Dimensions:** 10.5 x 3.75 x 13.5 in. \| **Contaminants Removed:** Heavy metals, chlorine, VOCs \| **Filtration Process:** Carbon \| **Certifications Water Quality:** WQA Gold Seal, NSF/ANSI \| **Tank Capacity**: NA \| **Filter Capacity:** 5,000 gal.

Keep in Mind - The carbon and VOC filters need to be replaced more often. If you are looking for a low maintenance countertop water filter with long-lasting filters, the Sans Countertop Water Purifier is a great choice. We appreciated the sleek, modern design and the ability to heat the water directly using the device instead of transferring it to a kettle or microwave. The filter uses a four-stage process, including a UV-C light, to remove contaminants and sediment from tap water. It arrived fully assembled—all we had to do before use was run four cycles with water to flush out the system. The filtered water appeared clearer in appearance, and the taste was slightly different. Making hot water with the purifier is super easy; just place a mug on the tray and press the hot water button on the machine. The water takes a few seconds to heat up, but once it does, it’s the perfect temperature for a warm beverage. Green tea had a cleaner, less chemical taste when we prepared it with the purified water. We love that the reverse-osmosis filter can last for up to two years (when most filters need to be replaced about once a year), though it’s important to note that the carbon and VOC filters need to be changed approximately every 12 months. A [pack of all three filters](https://www.livesans.com/products/sans-water-purifier-filter-bundle) is available for \$125, which is fairly cost effective. **Product Details: Dimensions:** 17\.3 x 6.7 x 12.2 in. \| **Contaminants Removed:** Fluoride, heavy metals, PFAS, antibiotics, arsenic, hormones, minerals, microplastics \| **Filtration Process:** Reverse osmosis \| **Certifications:** NSF \| **Tank Capacity:** 0\.9 gal. \| **Filter Capacity:** 600 gal.

Keep in Mind - The spout is too low for larger bottles to fit underneath. The AquaTru system uses four-stage reverse-osmosis filtration to remove toxins, [heavy metals](https://www.bhg.com/signs-you-need-an-iron-filter-11739016), and dissolved solids from your tap water. We were immediately impressed by the easy setup process, which uses color-coding to simplify the installation of the three filtration tanks. After installing the tanks, we ran four cycles (each took 10 to 15 minutes) before drinking the water, per the instructions. The water test strip we used to evaluate our tap water prior to filtration showed a high level of nitrates; when we repeated the water test after filtration, the level had gone down to zero. We didn’t notice a big difference in the taste of the water after filtration, but it did seem slightly cleaner. The reservoir holds 3 quarts of filtered water (or about 12 cups); we found ourselves refilling it about every other day, which was not overly burdensome since it only takes a few minutes to filter new water. The system was a nice size for our tester’s kitchen, which has plenty of counter space, but it may be too bulky for [small kitchens](https://www.bhg.com/kitchen/small/our-favorite-small-kitchens-that-live-large/). Unlike some of our other top picks, it doesn’t include a pitcher—instead, you dispense the water directly into your preferred drinking vessel. It’s worth noting that the spout is too low for larger water bottles to fit underneath. As with other multi-stage models, the different filters have different expected lifespans (between six months and two years). You can purchase a [pack of replacement filters](https://aquatruwater.com/product/two-year-classic-combo-filter-pack) designed to last two years for \$150, which we think is a pretty good value. The manufacturer suggests cleaning the reservoir about once a week. **Product Details: Dimensions** 14 x 12 x 14 in. \| **Contaminants Removed:** PFOA, PFOS, lead, fluoride, chlorine, microplastics \| **Filtration Process:** Reverse osmosis \| **Certifications:** NSF \| **Tank Capacity:** 1 gal. \| **Filter Capacity:** 600 gal.

If you’re on a tighter budget, we love the [Brondell Cypress](https://www.brondell.com/cypress-counter-top-water-filter/)—an effective filtration system that costs less than \$200. ## Our Testing Process To find the best countertop water filters, we evaluated seven options based on five factors: water smell, water taste, ease of use, design, and the value for cost. We first tasted our unfiltered tap water, noting any cloudiness or smell. Then we set up the devices, paying close attention to the instructions. Next we sampled the filtered water, noting changes in appearance or taste. At least once during the testing period we used water test strips to compare the unfiltered tap against the filtered water. This helped us see if the filtration process removed contaminants and determine whether the results aligned with the marketing claims. We also compared upfront costs with the costs of the replacement filters to help determine a machine’s overall value. ![A person dispenses water from the AquaTru Countertop Water Filtration Purification System into a glass]() ![A person dispenses water from the AquaTru Countertop Water Filtration Purification System into a glass](https://www.bhg.com/thmb/i9QO22tI9TgBV8lm3XdP5SxWqL8=/4000x0/filters:no_upscale:strip_icc/bhg-aquatru-countertop-water-filtration-barrett-heald-10-3cb3ee507ab642eab76d2ec0ed1b185a.jpeg) Credit: Better Homes & Gardens ## What to Know About Countertop Water Filters Before Shopping ### Freestanding vs. Faucet-fed Countertop water filters come in a couple of variations. According to Lowe’s store manager Gary McCoy, “They may be attached directly to a faucet to provide filtered water straight from the tap or come as a standalone dispenser with a reservoir that can be placed anywhere.” [Faucet-fed filters](https://www.bhg.com/best-faucet-water-filters-7495121) mean you don’t have to worry about manually refilling, but they tend to be less renter-friendly, as most manufacturers recommend drilling a hole in your counter to feed the tube from under the sink. This more effectively hides the unsightly water feed line. If you’re [short on counter space](https://www.bhg.com/kitchen/small/small-kitchen-storage-ideas) and don’t have room right by your [kitchen sink](https://www.bhg.com/best-kitchen-sinks-7481712), a freestanding countertop water filter is more portable and practical. It’s also great to use on your nightstand if you’d like to have fresh water more easily accessible in the middle of the night. Most of the best countertop water filters on our list are freestanding, with the [Brondell Cypress](https://www.amazon.com/Brondell-Cypress-Countertop-Filter-Certified/dp/B00EEDJSES?tag=bhg-onsite-prod-20&ascsubtag=8399087) being the exception. While we enjoyed this feature, we didn’t love the visible water feed line, since we were unwilling to drill a hole through the countertop for the test. Another con is that it’s not compatible with pull-down faucets. ### Dimensions Most countertop water filters on our list are between the size of a toaster and a larger coffee maker. In addition to counter space, you need enough clearance above the filter to fill or remove the tank. If you’re placing it underneath low kitchen cabinets, like we did with the [Sans Countertop Water Purifier](https://www.livesans.com/products/water-purifier?variant=44273087873268), the appliance may need to be moved when it’s time to refill. ### Capacity There are two different capacities listed for most countertop water filters—tank capacity and filter capacity. These numbers are easily confused but mean different things. Water tank capacity refers to how much filtered water the appliance can hold. The options on our list range from 0.9 to over 1 gallon. Filter capacity, on the other hand, indicates roughly how much water the appliance can filter effectively before it needs replacing. If you can’t find a specific number, some manufacturers list the approximate filter lifespan instead. This varies from six months to two years, and differs depending on the type of filter. ### Certifications There are so many contaminants that can show up in tap water, and manufacturers make wildly different claims about what filters can reduce or eliminate. So, what’s the best countertop water filter for removing the most dangerous contaminants? And how do you know if a manufacturer’s claims are legit? “You can look for National Sanitation Foundation (NSF) certification, which indicates the filter has been independently tested to verify, among other things, that it reduces the contaminants it claims to reduce,” McCoy says. All of the filters on our list have the NSF certification. Another common certification is from the American National Standards Institute, or ANSI. You’ll often see NSF or ANSI certifications listed with a specific number. Standards 42, 53, and 401 are considered the industry trifecta for removing tastes and odors (42), traces of medicines and other chemicals (401), and major health concerns (53) such as asbestos, lead, and mercury. It’s important to look for these specific numbers if a manufacturer lists an appliance as being NSF certified to understand which contaminants the water filter will actually remove. However, [Sydney Evans](https://www.ewg.org/news-insights/our-experts/sydney-evans), senior science analyst at the Environmental Working Group, notes that not all filters work on all contaminants. “Some organizations like NSF and WQA provide some level of third-party verification that the filter actually meets the manufacturer's claims. But it is important to find out exactly what those manufacturer's claims are when shopping for a water filter,” Evans says. ### Filter Lifespan Like with a water filter pitcher, the filter components don’t last forever. Most of the countertop water filters we tested estimate that you’ll need to replace the filters every six months to two years. However, many devices have multiple filters that have different requirements depending on the type. It’s all dependent on how much water has gone through the filter; the older the filter gets, the less powerful it becomes. “Over time, contaminants take up more and more space and these filters become less and less effective, and the filter cartridge needs to be replaced,” Evans says. Evans notes that the lifespan of a countertop water filter cartridge can vary significantly depending on the brand, model, and filter type. “It's essential to take into account both the initial cost of the filter and how often replacement cartridges are required,” she says. “It's reasonable to expect that filter efficacy may decrease over time, highlighting the importance of regular cartridge replacement to maintain optimal water quality.” All of this impacts the overall cost of the device. To look at value, we evaluated the upfront cost of the unit, replacement frequency, and estimated annual filter maintenance cost. The annual cost of maintenance ranged from \$62 per year for the [Sans Countertop Water Purifier](https://www.livesans.com/products/water-purifier?variant=44273087873268) to \$150 per year for the [Bluevua Reverse Osmosis Countertop Water Filter](https://www.amazon.com/Bluevua-RO100ROPOT-Countertop-Purification-Filtration/dp/B09KRDK677?th=1&tag=bhg-onsite-prod-20&ascsubtag=8399087), which features three filters that are replaced at different times. ### Ease of Use and Maintenance The best countertop water filters should be as easy to use in terms of refilling water. We tested several different designs, noting which appliances were too big to fit under the sink and fill directly with faucet water. And for removable water tanks, we noted how easy they were to grip, fill, and pour. If low mobility is a concern, you may want to consider a faucet-fed filter to bypass carrying heavy water tanks. However, for faucet-fed filters, the initial installation can be a pain, and fitting a hose to your kitchen sink may not be ideal. Regardless of ergonomics, it’s important to note the specific cleaning instructions for the water reservoir and filtered water tank, as they vary by brand and design. A water filter system’s ease of use is an important indicator of how much use a machine will get. ![A person presses a button on the Bluevua Reverse Osmosis Countertop Water Filter]() ![A person presses a button on the Bluevua Reverse Osmosis Countertop Water Filter](https://www.bhg.com/thmb/2Q9CTNDE3E7CcVy3J42r074TacA=/2842x0/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-11-a4521c93fb9249d9a28cd1fed3fb2238.jpeg) Credit: Better Homes & Gardens ## Your Questions, Answered ### What are the advantages and disadvantages of countertop water filters? “Countertop and dispenser-style filters are generally easy to set up,” Evans says. “They can be more affordable on average compared to more complex systems like [whole-house](https://www.bhg.com/best-whole-house-water-filters-8406113) or [under-sink filters](https://www.bhg.com/best-under-sink-water-filters-7378192). However, they do by nature have a limited capacity and require refilling, they take up space on your counter, and filters have to be maintained and replaced for them to be effective.” Another pain point for some: temperature. While the best countertop water filters save you fridge space, they don’t chill filtered water. Most countertop water filters keep filtered water at room temperature. ### What common contaminants do countertop water filters remove? “Some are certified to simply reduce contaminants that affect taste and smell, while others can reduce contaminants that impact your health,” McCoy says. “The most common contaminants the countertop water filters can remove are lead, mercury, and chlorine, although this can vary based on the filter you purchase.” ### Can I connect a countertop water filter to multiple faucets? If you’re hoping to use a countertop water filter at home as well as in an RV or another room in your home, double check the installation kit for adapter accessories. “Some water filters can be connected to multiple faucets, but it really will depend on the model you are purchasing,” McCoy says. ### What is the healthiest way to filter tap water? Is a countertop water filter better than a pitcher or an in-door refrigerator filter? Depends. Are you more likely to remember to change a filter if you see the appliance on display on your counter? According to Evans, “ the effectiveness of any filter relies on consistent and correct usage.” ## Who We Are [Alice Knisley Matthias](https://www.bhg.com/alice-knisley-matthias-7546613) is a writer who covers kitchen products and appliances for *Better Homes & Gardens.* To write this article, she consulted insights from our in-house touchless countertop water filter testing and tested one in her home.

Having relied on a refrigerated [filtered water pitcher](https://www.bhg.com/how-to-clean-brita-pitcher-8713066) for years, I was eager to try a countertop version instead. My previous water filter took up precious refrigerator space, and I was never quite sure how well it was [purifying my drinking water](https://www.bhg.com/water-testing-pitcher-11730674). Countertop water filters, on the other hand, promised to be a better choice for getting rid of contaminants and microplastics. According to water sommelier [Martin Riese](https://www.martin-riese.com/). “A good glass of [drinking water should be odorless](https://www.bhg.com/why-does-my-water-smell-8718691), colorless, and will have a refreshing and crisp taste due to the minerals dissolved in the water.” There are many different options at various price points, from basic, affordable filters that remove common contaminants like chlorine to reverse-osmosis systems that “filter out many contaminants like lead, PFAS and [microplastics](https://www.bhg.com/household-items-releasing-microplastics-11752367),” Riese says. ### What We Tested We carefully selected the best countertop water filters for every household, taking into consideration **filter lifespan**, **certifications**, **upfront and maintenance costs**, **water capacity**, and **ease of use**. For more information on how we tested countertop water filters, check out [our testing process](https://www.bhg.com/best-countertop-water-filters-8399087#toc-our-testing-process) below. Why You Should Get It - It’s a plug-and-play option that is easy to use and effective, with fast purification cycles. Keep in Mind - The leftover water from each cycle might feel wasteful to some users. The Bluevua Reverse Osmosis Countertop Water Filter impressed me with its ease of use and comprehensive filtration, as well as its design. It’s a plug-and-play system that took me only about 30 minutes to set up, including reading the instructions, washing the pieces, and running the system cycle several times. The filter uses five levels of filtration, including a remineralization filter, to deliver purified water into a carafe made of high borosilicate glass. During testing, the filtered water came out consistently clear and clean-tasting, even with frequent cycling thanks to several teenagers and adults constantly filling travel mugs and water bottles. To refill, remove the tank from the base, fill it with tap water, and replace it for another cycle. Speed is another plus with the system, as it runs a cycle in a matter of minutes. The display panel gives a clear numerical "before" and "after" reading on the front of the machine at the start and finish of each cycle. We appreciate how easy the water filter system is to use, but there is a decent amount of leftover water from a cycle that is not for consumption. While I used it to water plants and mix [homemade cleaning solutions](https://www.bhg.com/homekeeping/house-cleaning/cleaning-products-tools/homemade-cleaners/), some might find this aspect a bit wasteful. Replacement filters are \$50 and one filter should last about a year. I found this to be pretty reasonable, especially compared to the cost of buying bottled water on a regular basis. **Product Details: Dimensions:** 10.9 x 15.4 x 14.3 in. \| **Contaminants Removed:** Heavy metals, lead, mercury, chlorine, PFOA, PFOS, fluoride ,sulfates \| **Filtration Process:** Reverse osmosis \| **Certifications:** WQA, NSF, ANIS\| **Tank Capacity:** 1\.05 gal. \| **Filter Capacity:** 1,050 gal. \| **Warranty:** One year - ![Water tests strips before and after using the Bluevua Reverse Osmosis Countertop Water Filter](https://www.bhg.com/thmb/L4mBcM3NAFeMr44BnecfhsHhucg=/fit-in/1500x1000/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-04-comp-9f5b4c2e599744e19347f8ba0b0221ca.jpeg) Credit: Better Homes & Gardens - ![A person fills the Bluevua Reverse Osmosis Countertop Water Filter water tank with water](https://www.bhg.com/thmb/pidl_nyLtLDPRqWknGJFAFx5aoM=/fit-in/1500x2667/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-07-061b9bf1bbec47149f93e5863bbdb837.jpeg) Credit: Better Homes & Gardens - ![A person adds a water tank to the back of the Bluevua Reverse Osmosis Countertop Water Filter](https://www.bhg.com/thmb/6b2bv8P1NvPEXuhOxHqod5_BK_Y=/fit-in/1500x2155/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-12-eff9211ae6954bd9b18effbe62fa09c8.jpeg) Credit: Better Homes & Gardens - ![The Bluevua Reverse Osmosis Countertop Water Filter while in use](https://www.bhg.com/thmb/79LzlaTjiWTxyo1bfH9Avoykvg0=/fit-in/1500x2667/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-09-a17e376d52aa4e1484c71120fe8f9c7a.jpeg) Credit: Better Homes & Gardens - ![The digital display on the Bluevua Reverse Osmosis Countertop Water Filter](https://www.bhg.com/thmb/_Qjen41c_jPHn-0aTGyFba3GA_M=/fit-in/1500x2040/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-watwr-filter-alice-knisley-matthias-10-8ecdf7debdba4688ab6a28abc904833b.jpeg) Credit: Better Homes & Gardens - ![Water tests strips before and after using the Bluevua Reverse Osmosis Countertop Water Filter](https://www.bhg.com/thmb/aPpmPSiku4yHn0woWDZhB6v78-0=/fit-in/200x1000/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-04-comp-9f5b4c2e599744e19347f8ba0b0221ca.jpeg) - ![A person fills the Bluevua Reverse Osmosis Countertop Water Filter water tank with water](https://www.bhg.com/thmb/T0cEgminax5zT2iYAvo-E4MZY4I=/fit-in/200x2667/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-07-061b9bf1bbec47149f93e5863bbdb837.jpeg) - ![A person adds a water tank to the back of the Bluevua Reverse Osmosis Countertop Water Filter](https://www.bhg.com/thmb/BIyTePfb3tneYDgE2nI63GRsSzc=/fit-in/200x2155/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-12-eff9211ae6954bd9b18effbe62fa09c8.jpeg) - ![The Bluevua Reverse Osmosis Countertop Water Filter while in use](https://www.bhg.com/thmb/dO_IpZBZFIQhrsJvzj-KoUtc8fM=/fit-in/200x2667/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-water-filter-alice-knisley-matthias-09-a17e376d52aa4e1484c71120fe8f9c7a.jpeg) - ![The digital display on the Bluevua Reverse Osmosis Countertop Water Filter](https://www.bhg.com/thmb/-S-MxfRsK9G6q6utejoWPkSDUIo=/fit-in/200x2040/filters:no_upscale:strip_icc/bhg-bluevua-reverse-osmosis-countertop-watwr-filter-alice-knisley-matthias-10-8ecdf7debdba4688ab6a28abc904833b.jpeg) Why You Should Get It - There is no tank or reservoir to fill or empty, since the system is attached to the kitchen faucet. Keep in Mind - The faucet adapter The Brondell Countertop Water Filtration System is both more affordable *and* more attractive than other options we tested. It’s minimal, with few controls, and matched our tester’s [modern kitchen decor](https://www.bhg.com/industrial-kitchen-ideas-7567247). Plus, it’s compact, so it’s a good option for smaller kitchens. Installation is simple—the most complicated part is attaching the faucet adapter to divert water directly from the sink, but even this took us no more than five minutes. All in all, it was about 20 minutes from opening the package to drinking our first glass of filtered water. This included running the water for 10 minutes before using. The Brondell uses three stages of filtration, including a composite filter for sediments and a carbon filter to improve water taste and smell and remove VOCs and other contaminants. We noticed that the filtered water had a better overall flavor compared to the unfiltered tap, which usually tastes and smells like chlorine. Despite the positives, we noticed a few downsides as well. The water feed line that connects to the faucet is exposed, which wasn’t our favorite aesthetically, and though the upfront cost of the device is lower than many, the maintenance cost for buying [replacement filters](https://www.brondell.com/cypress-replacement-filters/) is \$150 a year. It’s also worth noting that the faucet attachment only works with [traditional faucets](https://www.bhg.com/types-of-faucets-6830890), not more modern pull-out or [spray faucets](https://www.bhg.com/types-of-faucets-8644435). You can, however, purchase a compatible [T-valve](https://www.brondell.com/cypress-h630-alternate-installation-t-valve/) that lets you connect the filter directly to the water supply underneath the sink. **Product Details: Dimensions:** 10.5 x 3.75 x 13.5 in. \| **Contaminants Removed:** Heavy metals, chlorine, VOCs \| **Filtration Process:** Carbon \| **Certifications Water Quality:** WQA Gold Seal, NSF/ANSI \| **Tank Capacity**: NA \| **Filter Capacity:** 5,000 gal.

Keep in Mind - The carbon and VOC filters need to be replaced more often. If you are looking for a low maintenance countertop water filter with long-lasting filters, the Sans Countertop Water Purifier is a great choice. We appreciated the sleek, modern design and the ability to heat the water directly using the device instead of transferring it to a kettle or microwave. The filter uses a four-stage process, including a UV-C light, to remove contaminants and sediment from tap water. It arrived fully assembled—all we had to do before use was run four cycles with water to flush out the system. The filtered water appeared clearer in appearance, and the taste was slightly different. Making hot water with the purifier is super easy; just place a mug on the tray and press the hot water button on the machine. The water takes a few seconds to heat up, but once it does, it’s the perfect temperature for a warm beverage. Green tea had a cleaner, less chemical taste when we prepared it with the purified water. We love that the reverse-osmosis filter can last for up to two years (when most filters need to be replaced about once a year), though it’s important to note that the carbon and VOC filters need to be changed approximately every 12 months. A [pack of all three filters](https://www.livesans.com/products/sans-water-purifier-filter-bundle) is available for \$125, which is fairly cost effective. **Product Details: Dimensions:** 17\.3 x 6.7 x 12.2 in. \| **Contaminants Removed:** Fluoride, heavy metals, PFAS, antibiotics, arsenic, hormones, minerals, microplastics \| **Filtration Process:** Reverse osmosis \| **Certifications:** NSF \| **Tank Capacity:** 0\.9 gal. \| **Filter Capacity:** 600 gal.

Keep in Mind - The spout is too low for larger bottles to fit underneath. The AquaTru system uses four-stage reverse-osmosis filtration to remove toxins, [heavy metals](https://www.bhg.com/signs-you-need-an-iron-filter-11739016), and dissolved solids from your tap water. We were immediately impressed by the easy setup process, which uses color-coding to simplify the installation of the three filtration tanks. After installing the tanks, we ran four cycles (each took 10 to 15 minutes) before drinking the water, per the instructions. The water test strip we used to evaluate our tap water prior to filtration showed a high level of nitrates; when we repeated the water test after filtration, the level had gone down to zero. We didn’t notice a big difference in the taste of the water after filtration, but it did seem slightly cleaner. The reservoir holds 3 quarts of filtered water (or about 12 cups); we found ourselves refilling it about every other day, which was not overly burdensome since it only takes a few minutes to filter new water. The system was a nice size for our tester’s kitchen, which has plenty of counter space, but it may be too bulky for [small kitchens](https://www.bhg.com/kitchen/small/our-favorite-small-kitchens-that-live-large/). Unlike some of our other top picks, it doesn’t include a pitcher—instead, you dispense the water directly into your preferred drinking vessel. It’s worth noting that the spout is too low for larger water bottles to fit underneath. As with other multi-stage models, the different filters have different expected lifespans (between six months and two years). You can purchase a [pack of replacement filters](https://aquatruwater.com/product/two-year-classic-combo-filter-pack) designed to last two years for \$150, which we think is a pretty good value. The manufacturer suggests cleaning the reservoir about once a week. **Product Details: Dimensions** 14 x 12 x 14 in. \| **Contaminants Removed:** PFOA, PFOS, lead, fluoride, chlorine, microplastics \| **Filtration Process:** Reverse osmosis \| **Certifications:** NSF \| **Tank Capacity:** 1 gal. \| **Filter Capacity:** 600 gal.

Keep in Mind - The machine is large and unpleasantly loud when operating. A simple set-up and solid build with touchscreen control make the Waterdrop A1 Reverse Osmosis Hot Cold Dispenser a reliable choice for large, busy households. The ability to produce both hot and cold water is a plus—we appreciated that we could [make tea](https://www.bhg.com/best-iced-tea-makers-7564601) or hot chocolate with water dispensed directly from the machine. The test strips that we used during the testing period indicated that the machine, with its seven-stage filtration, effectively removed bacteria. However, the unit is on the larger side compared to others on our list and requires a considerable amount of counter space.

If you’re on a tighter budget, we love the [Brondell Cypress](https://www.brondell.com/cypress-counter-top-water-filter/)—an effective filtration system that costs less than \$200. ## Our Testing Process To find the best countertop water filters, we evaluated seven options based on five factors: water smell, water taste, ease of use, design, and the value for cost. We first tasted our unfiltered tap water, noting any cloudiness or smell. Then we set up the devices, paying close attention to the instructions. Next we sampled the filtered water, noting changes in appearance or taste. At least once during the testing period we used water test strips to compare the unfiltered tap against the filtered water. This helped us see if the filtration process removed contaminants and determine whether the results aligned with the marketing claims. We also compared upfront costs with the costs of the replacement filters to help determine a machine’s overall value. Credit: Better Homes & Gardens ## What to Know About Countertop Water Filters Before Shopping ### Freestanding vs. Faucet-fed Countertop water filters come in a couple of variations. According to Lowe’s store manager Gary McCoy, “They may be attached directly to a faucet to provide filtered water straight from the tap or come as a standalone dispenser with a reservoir that can be placed anywhere.” [Faucet-fed filters](https://www.bhg.com/best-faucet-water-filters-7495121) mean you don’t have to worry about manually refilling, but they tend to be less renter-friendly, as most manufacturers recommend drilling a hole in your counter to feed the tube from under the sink. This more effectively hides the unsightly water feed line. If you’re [short on counter space](https://www.bhg.com/kitchen/small/small-kitchen-storage-ideas) and don’t have room right by your [kitchen sink](https://www.bhg.com/best-kitchen-sinks-7481712), a freestanding countertop water filter is more portable and practical. It’s also great to use on your nightstand if you’d like to have fresh water more easily accessible in the middle of the night. Most of the best countertop water filters on our list are freestanding, with the [Brondell Cypress](https://www.amazon.com/Brondell-Cypress-Countertop-Filter-Certified/dp/B00EEDJSES?tag=bhg-onsite-prod-20&ascsubtag=8399087) being the exception. While we enjoyed this feature, we didn’t love the visible water feed line, since we were unwilling to drill a hole through the countertop for the test. Another con is that it’s not compatible with pull-down faucets. ### Dimensions Most countertop water filters on our list are between the size of a toaster and a larger coffee maker. In addition to counter space, you need enough clearance above the filter to fill or remove the tank. If you’re placing it underneath low kitchen cabinets, like we did with the [Sans Countertop Water Purifier](https://www.livesans.com/products/water-purifier?variant=44273087873268), the appliance may need to be moved when it’s time to refill. ### Capacity There are two different capacities listed for most countertop water filters—tank capacity and filter capacity. These numbers are easily confused but mean different things. Water tank capacity refers to how much filtered water the appliance can hold. The options on our list range from 0.9 to over 1 gallon. Filter capacity, on the other hand, indicates roughly how much water the appliance can filter effectively before it needs replacing. If you can’t find a specific number, some manufacturers list the approximate filter lifespan instead. This varies from six months to two years, and differs depending on the type of filter. ### Certifications There are so many contaminants that can show up in tap water, and manufacturers make wildly different claims about what filters can reduce or eliminate. So, what’s the best countertop water filter for removing the most dangerous contaminants? And how do you know if a manufacturer’s claims are legit? “You can look for National Sanitation Foundation (NSF) certification, which indicates the filter has been independently tested to verify, among other things, that it reduces the contaminants it claims to reduce,” McCoy says. All of the filters on our list have the NSF certification. Another common certification is from the American National Standards Institute, or ANSI. You’ll often see NSF or ANSI certifications listed with a specific number. Standards 42, 53, and 401 are considered the industry trifecta for removing tastes and odors (42), traces of medicines and other chemicals (401), and major health concerns (53) such as asbestos, lead, and mercury. It’s important to look for these specific numbers if a manufacturer lists an appliance as being NSF certified to understand which contaminants the water filter will actually remove. However, [Sydney Evans](https://www.ewg.org/news-insights/our-experts/sydney-evans), senior science analyst at the Environmental Working Group, notes that not all filters work on all contaminants. “Some organizations like NSF and WQA provide some level of third-party verification that the filter actually meets the manufacturer's claims. But it is important to find out exactly what those manufacturer's claims are when shopping for a water filter,” Evans says. ### Filter Lifespan Like with a water filter pitcher, the filter components don’t last forever. Most of the countertop water filters we tested estimate that you’ll need to replace the filters every six months to two years. However, many devices have multiple filters that have different requirements depending on the type. It’s all dependent on how much water has gone through the filter; the older the filter gets, the less powerful it becomes. “Over time, contaminants take up more and more space and these filters become less and less effective, and the filter cartridge needs to be replaced,” Evans says. Evans notes that the lifespan of a countertop water filter cartridge can vary significantly depending on the brand, model, and filter type. “It's essential to take into account both the initial cost of the filter and how often replacement cartridges are required,” she says. “It's reasonable to expect that filter efficacy may decrease over time, highlighting the importance of regular cartridge replacement to maintain optimal water quality.” All of this impacts the overall cost of the device. To look at value, we evaluated the upfront cost of the unit, replacement frequency, and estimated annual filter maintenance cost. The annual cost of maintenance ranged from \$62 per year for the [Sans Countertop Water Purifier](https://www.livesans.com/products/water-purifier?variant=44273087873268) to \$150 per year for the [Bluevua Reverse Osmosis Countertop Water Filter](https://www.amazon.com/Bluevua-RO100ROPOT-Countertop-Purification-Filtration/dp/B09KRDK677?th=1&tag=bhg-onsite-prod-20&ascsubtag=8399087), which features three filters that are replaced at different times. ### Ease of Use and Maintenance The best countertop water filters should be as easy to use in terms of refilling water. We tested several different designs, noting which appliances were too big to fit under the sink and fill directly with faucet water. And for removable water tanks, we noted how easy they were to grip, fill, and pour. If low mobility is a concern, you may want to consider a faucet-fed filter to bypass carrying heavy water tanks. However, for faucet-fed filters, the initial installation can be a pain, and fitting a hose to your kitchen sink may not be ideal. Regardless of ergonomics, it’s important to note the specific cleaning instructions for the water reservoir and filtered water tank, as they vary by brand and design. A water filter system’s ease of use is an important indicator of how much use a machine will get. Credit: Better Homes & Gardens ## Your Questions, Answered ### What are the advantages and disadvantages of countertop water filters? “Countertop and dispenser-style filters are generally easy to set up,” Evans says. “They can be more affordable on average compared to more complex systems like [whole-house](https://www.bhg.com/best-whole-house-water-filters-8406113) or [under-sink filters](https://www.bhg.com/best-under-sink-water-filters-7378192). However, they do by nature have a limited capacity and require refilling, they take up space on your counter, and filters have to be maintained and replaced for them to be effective.” Another pain point for some: temperature. While the best countertop water filters save you fridge space, they don’t chill filtered water. Most countertop water filters keep filtered water at room temperature. ### What common contaminants do countertop water filters remove? “Some are certified to simply reduce contaminants that affect taste and smell, while others can reduce contaminants that impact your health,” McCoy says. “The most common contaminants the countertop water filters can remove are lead, mercury, and chlorine, although this can vary based on the filter you purchase.” ### Can I connect a countertop water filter to multiple faucets? If you’re hoping to use a countertop water filter at home as well as in an RV or another room in your home, double check the installation kit for adapter accessories. “Some water filters can be connected to multiple faucets, but it really will depend on the model you are purchasing,” McCoy says. ### What is the healthiest way to filter tap water? Is a countertop water filter better than a pitcher or an in-door refrigerator filter? Depends. Are you more likely to remember to change a filter if you see the appliance on display on your counter? According to Evans, “ the effectiveness of any filter relies on consistent and correct usage.” ## Who We Are [Alice Knisley Matthias](https://www.bhg.com/alice-knisley-matthias-7546613) is a writer who covers kitchen products and appliances for *Better Homes & Gardens.* To write this article, she consulted insights from our in-house touchless countertop water filter testing and tested one in her home.
