Quick answer: Best PFAS water filters by category
The best water filter for PFAS is the Waterdrop G3P800 based on our dedicated 14-analyte panel, daily use, and under-sink performance. AquaTru Classic produced the same 14-of-14 not-detected result for people who need a countertop system. The other three picks serve different budgets and installation needs, but their evidence for these persistent chemicals, often called forever chemicals, is not identical. Use the comparison below to match the strength of the evidence to the drinking water you want to treat.
- #1. Best for PFAS Removal: Waterdrop G3P800
- #2. Best Under-Sink RO: Cloud RO
- #3. Best Countertop RO: AquaTru Classic
- #4. Best Pitcher: Clearly Filtered Pitcher
- #5. Best Under-Sink (No Power): Clearly Filtered 3-Stage
Our PFAS testing and selection process
Every filter on this page has been independently lab-tested through Tap Score. For PFAS specifically, we ran dedicated 14-analyte panels on the Waterdrop G3P800 and AquaTru Classic – both returned every compound not detected. The remaining filters were tested for broader contaminant removal including THMs, lead, chlorine, and TDS.
How we score
What we weighed, by filter type:
- Reverse Osmosis (Under-Sink): PFAS panel results, flow rate, waste ratio, and NSF certifications.
- Countertop RO: PFAS panel results, portability, space efficiency, and per-gallon cost.
- Pitchers: certified PFAS reduction claims, taste, and contaminant removal transparency.
- Under-Sink Inline: certified PFAS claims, ease of setup, and maintenance cost.
What earned a spot
These aren’t one-week trial runs. The Waterdrop G3P800 is our daily under-sink RO, and the AquaTru ran in our kitchen for years before we switched. The Clearly Filtered pitcher gets regular use as a backup and at family BBQs. Every pick has been used in a real household, not just unboxed for photos.
- Does it have independent PFAS lab data – or just manufacturer claims?
- What did our Tap Score panels actually show after filtration?
- How much hassle is setup, upkeep, and filter swaps?
- What’s the real cost per year to run?
For PFAS specifically, we required either independent lab data from our own testing or published third-party certification results. Systems that only offered manufacturer claims didn’t make the top spots. The picks here each earned their place by excelling where it matters most – verified contaminant removal, long-term value, or design that’s easier to live with.

After three years of daily use, the dedicated 14-analyte Tap Score panel is still the reason Waterdrop holds the top spot. All 14 PFAS compounds were not detected after treatment. The system also kept up when we filled gallon jugs, and its smart faucet made filter-life tracking simple.
Main tradeoff: It needs electricity, costs more than an entry-level RO system, and the faucet has needed an occasional retightening after years of family use. It also runs a little louder during regeneration than it did when new.

#2. Cloud RO – Best Under-Sink RO
Full scoring basis
- Filtration (RO + PFAS) (45%): 4-stage RO with sediment, carbon block, RO membrane, and built-in remineralization. NSF/ANSI 53 certified for PFOA/PFOS removal (SGS Labs). Tap Score 97/99 – THMs, lead, fluoride, copper all to ND. TDS dropped from 187 to 66 ppm.
- Flow/Pressure (20%): 2.8-gallon pressurized tank with battery-powered pump. Timed at 2:19 to fill a gallon – on par with tankless systems. Tank volume visible in real time via app. Never ran low in 12 months with a family of four.
- Install/Maint (10%): DIY-friendly – standard faucet hole and drain hookup. Filters bundled in annual kit (~$200). Battery estimated ~2 years per app data.
- Build (10%): Stainless tank + BPA-free plastics. App tracks filter life, TDS, gallons filtered, and tank volume in real time. No wall outlet required.
- Taste (5%), Cost (5%), App/Data (5%)
This is the RO we switched to after three years on the Waterdrop – and honestly, it’s our favorite to use day to day. Better-tasting water, smarter app, no outlet needed.
It sits at #2 because Waterdrop has a dedicated 14-analyte Tap Score PFAS panel. Cloud combines our Advanced City Water results with NSF/ANSI 53 certification for PFOA and PFOS. That is exact-model third-party PFAS evidence, but it does not cover the same 14-analyte post-treatment panel.
Features:
- Built-in remineralization – 66 ppm TDS out of the box, no add-on needed
- No outlet required – battery-powered pump, ~2 year estimated life
- App monitoring – real-time TDS, filter life, tank volume, gallons filtered
- 600 GPD flow rate – 2:19 to fill a gallon in our timed test

Context & Methods
“ND” = Not Detected above the lab reporting limit. THMs compared to EPA MCL (80 ppb). Barium compared to EPA MCL (2 ppm). Lead compared to EPA Action Level (15 ppb). Sampling protocol: 2.5-gallon storage tank was flushed three complete times (~7.5 gallons). To ensure no residuals, we doubled that volume and processed ~17 gallons total (including wastewater) before collection. After the final flush, the faucet line was purged for 90 seconds prior to sampling; analysis performed by Tap Score.

Cloud RO has stayed quiet, and its tank has not run low during 12 months of use in a four-person household. The battery-powered pump solves a real installation problem when there is no outlet below the sink. Remineralization brought our sample to 66 ppm TDS and produced a less-flat taste than standard RO water.
Main tradeoff: Cloud sells its filters as a bundled annual kit rather than individual cartridges. Its Bluetooth-only app cannot be checked away from home, the pressurized tank takes more room than a tankless unit, and the measured 1:1 waste ratio trails Waterdrop’s efficiency.

#3. AquaTru Classic – Best Countertop RO for PFAS
Full scoring basis
- Filtration (PFAS Tested) (45%): reverse osmosis barrier + carbon polishing; our post-treatment Tap Score panel returned all 14 PFAS analytes not detected
- Flow/Pressure (20%): steady countertop RO delivery; no plumbing needed
- Install/Maint (10%): plug-and-play; filters swap out in minutes
- Build (10%): solid countertop form factor; NSF-certified parts
- Taste (5%), Cost (5%), Certs (5%)
Before switching to a dedicated under-sink system (we now use the Cloud RO), this was our first real step toward filtering out the junk – and it held up better than expected.
The AquaTru’s plug-and-play design made it easy to start filtering without plumbing or tools. We ran a dedicated Tap Score PFAS panel on it after 3+ years of use with fresh filters – all 14 analytes came back not detected. The certifications are solid, but the lab data is what settled it for us.
🔍 What We Like About It
- Zero-install setup: Just plug it in, fill the tank, and you’re filtering – no plumbing, drilling, or sink clearance needed.
- RO filtration without the bulk: Delivers the same membrane tech you’d find in a full-size system but in a compact, countertop-friendly form.
- Digital filter life indicator: Takes the guesswork out of knowing when to replace filters – no sticker dates or tracking apps.
- Certified protection: NSF 42, 53, 58, 401, and P473 – few countertop units come close.
- Great starter system for families: Clean-tasting water, low maintenance, and easy enough for anyone to refill or reset.

AquaTru is the countertop pick for renters and anyone who wants reverse osmosis without plumbing. We used it for daily drinking water before moving to an under-sink system, and its dedicated Tap Score panel returned all 14 PFAS analytes not detected after treatment.
Main tradeoff: It needs counter space, a power outlet, and manual refills. The low spout also makes tall bottles awkward to fill unless you hold them near the edge of the counter.

Clearly Filtered is the easiest pick here to move, store, or use without installation. The company publishes third-party results for a wider group of PFAS than PFOA and PFOS alone. We keep the pitcher as an RO backup and bring it outside for family BBQs.
Main tradeoff: A large household may refill it several times a day. We rinse the lid and reservoir weekly, especially in warm weather, and treat slower filtration as a signal to check the cartridge. The lid also needs careful handling because it can crack.

- Build Quality (15%): solid housings, leak-free fittings
- Install & Maint (10%): quick-change cartridges; clean mounting
- Operating Cost (5%), Flow/Pressure (5%)
If you want high-level protection without the hassle of reverse osmosis or a power hookup, this 3-stage under-sink system hits the sweet spot.
It’s NSF certified to remove 200+ contaminants – including chlorine, lead, microplastics, and PFAS – while maintaining solid flow and easy install.
We tested this system in our home. Its direct line-in design gave us under-sink filtration without an outlet, storage tank, or drain connection.
🔍 What Stood Out During Testing
- Targets 230+ contaminants – including PFAS, lead, and pharmaceuticals
- Installs inline under your sink – no tank, no power, no hassle

We tested the Clearly Filtered 3-Stage in our home. The direct line-in installation took about 20 minutes and required no tank, electricity, or drain connection. It is the practical pick when you want an under-sink PFAS filter without reverse osmosis.
Main tradeoff: The housing can feel tight during cartridge changes, and there is no flow indicator. A high-use household may need new filters in 9–12 months rather than waiting for the longest advertised interval. Replacement filters cost about $170 per year for the household we tested.

Our recommendation
See full details →How to choose a water filter for PFAS
Start with the evidence, then choose the format you can live with. Our strongest direct PFAS evidence comes from the Waterdrop G3P800 and AquaTru Classic. In separate Tap Score panels, all 14 PFAS analytes were not detected after treatment. Cloud RO has certified PFOA and PFOS reduction, while the two Clearly Filtered options rely on manufacturer-published PFAS testing. We keep those evidence types separate because they do not answer the same question.
Pick the treatment location first
For drinking and cooking water, a point-of-use filter is the clearest choice. Waterdrop and Cloud fit below the sink. AquaTru sits on the counter and needs no plumbing. The Clearly Filtered pitcher is portable, while the Clearly Filtered 3-Stage gives you a non-RO under-sink option without an outlet or drain connection.
What if you need to remove PFAS and microplastics?
A PFAS result does not automatically verify microplastic reduction. Our samples on this page were not dedicated microplastics tests, so we do not present them as independent proof of microplastic removal. See our lab-based guide to water filters for microplastics for that separate comparison.
Why we don’t recommend a whole-house PFAS filter
We do not currently recommend a whole-house system as the primary PFAS treatment. The whole-house filters we have tested do not have the same direct PFAS evidence as the leading point-of-use systems on this page. If PFAS is your main concern, treat the water you drink and cook with first.
Which treatment method should you choose?
Reverse osmosis has the strongest direct QWL evidence on this page. Carbon and ion-exchange filters can also reduce PFAS when the exact product has supporting test data. Do not infer PFAS performance from the treatment label alone. Our separate guides explain how to remove PFAS from water and how reverse osmosis performs against PFAS.
How to verify a PFAS-certified water filter
NSF/ANSI 53 and NSF/ANSI 58 can include PFOA and PFOS reduction claims, but the standard number alone is not enough. Check the product’s actual listing or performance data sheet to confirm which claims apply to that model. NSF/ANSI 473 is another PFAS-focused standard that may appear on drinking-water treatment products.
For Waterdrop and AquaTru, we link directly to IAPMO certification listings in the product sections above. An IAPMO listing identifies the exact model, applicable standard, and verified contaminant reduction claims. Check the IAPMO record rather than relying on a brand-level certification badge.
Our own evidence also has limits. A result from one household sample shows what happened under those test conditions. It does not guarantee identical performance in every home, with every PFAS compound, or at every point in a cartridge’s life.
Should you test your water first?
A certified laboratory test is the best way to learn whether PFAS are present and which compounds were detected. Home test strips and TDS meters cannot answer that question. If your utility does not publish current results, see our TapScore PFAS test review for the sampling process and what the report provides.
You do not need to delay treatment while waiting for a test if local data already show a PFAS problem. Choose a point-of-use filter with evidence that matches your concern, install it correctly, and replace its filters on schedule.
Once installed, replace cartridges on schedule. If you are concerned that performance has changed, use our PFAS filter troubleshooting guide rather than relying on taste or a TDS reading.
PFAS water filter questions
Do water filters remove PFAS from drinking water?
Some do, but the words “water filter” do not prove PFAS reduction. Look for an independently certified claim or a credible laboratory report for the exact model. Reverse osmosis filters, certain carbon filters, and some ion-exchange systems can reduce these chemicals. Basic sediment cartridges and ordinary taste-and-odor filters are not enough unless their performance data specifically name PFOA, PFOS, or other PFAS.
What is the cheapest way to remove PFAS from tap water?
A PFAS-tested filter pitcher usually has the lowest purchase price for treating tap water. The Clearly Filtered pitcher costs much less upfront than an under-sink system, though frequent replacement cartridges can narrow that gap over time. For a household that uses more drinking water, compare annual cost and certified capacity rather than price alone.
Will a Brita water filter remove PFAS?
Do not assume that every Brita filter reduces PFAS. Certification and contaminant-reduction claims vary by cartridge. Our Brita and PFAS guide checks the available claims and explains when a different filter makes more sense.
Can a shower filter remove PFAS?
We do not currently recommend a shower filter as the primary treatment for PFAS chemicals. The strongest evidence on this page applies to point-of-use systems for drinking and cooking water. If these water contaminants are present in your supply, start with the water you ingest and choose a system with documented PFAS performance.
PFAS are a large family of persistent chemicals, so no single result proves removal of every compound under every condition. Filter certifications, laboratory methods, cartridge capacity, and filtration rate all affect how much confidence you can place in a chemical-reduction claim. A water test can identify the compounds in your home’s drinking water, but the test should be performed by a qualified laboratory.
