Why LARQ Pitcher wins, and what it beats
Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 1 product it beats, so you can see exactly where the 5 points between the top and the bottom of this countertop filters ranking come from.

What to watch for in countertop filters
Beyond the PFAS grade, these are the things our graders recorded on the 15 countertop filters in this category. We assess from materials, brand statements and published research. We do not lab-test.
- Microplastics
Plastic fragments small enough to shed from a product into food, water or air without anyone seeing it.
Plausible but unconfirmed on 3 more, meaning nobody has ruled it out. EPA
- BPA and bisphenols
Chemicals that harden plastic and line metal cans, and the replacements sold as BPA-free.
Plausible but unconfirmed on 1 more, meaning nobody has ruled it out. NIEHS
- Undisclosed ingredients
Not a chemical. The absence of one, where we found no statement from the brand about what it uses.
Plausible but unconfirmed on 2 more, meaning nobody has ruled it out. FTC
Our grade says what a filter is made of, not how much PFAS it removes. For that, NSF, IAPMO and WQA keep public registers of units certified to reduce PFAS, and we reproduce them in full on the list of water filters certified to reduce PFAS. Check a model against both.

What the evidence says about PFAS in countertop filters
The US EPA set its first enforceable drinking water limits for PFAS in 2024, including 4.0 parts per trillion each for PFOA and PFOS, and in May 2026 proposed giving water systems until 2031 to meet those two while rescinding the limits for four other PFAS. For home filters, EPA tells shoppers to look for NSF/ANSI 53 or 58 certification for PFAS reduction, while cautioning that those certifications did not yet match its new limits. In one 2020 study, under-sink reverse osmosis and two-stage filters removed nearly all of the PFAS tested for, while carbon filters in pitchers and similar styles performed inconsistently.
- Regulatory filingIn 2024 the US EPA set legally enforceable drinking water limits for six PFAS, with individual limits for PFOA, PFOS, PFHxS, PFNA and HFPO-DA and a combined Hazard Index limit for mixtures of PFHxS, PFNA, HFPO-DA and PFBS. US EPA ↗
- Regulatory filingEPA’s 2024 limits for PFOA and PFOS in drinking water are 4.0 parts per trillion each, and EPA says its proposal to extend the compliance deadline does not change them. US EPA ↗
- Regulatory filingOn May 18, 2026 EPA proposed letting drinking water systems request two more years, to 2031, to meet the PFOA and PFOS limits, and separately proposed rescinding the limits for PFHxS, PFNA, HFPO-DA and the Hazard Index mixture that also covers PFBS. US EPA ↗

- Regulatory filingEPA cautions that, as of April 2024, PFAS filter certifications did not yet show a filter will remove PFAS down to its new drinking water limits, and says it is working with standard-setting bodies to update them. US EPA ↗
- Independent testIn a 2020 study, Duke University and NC State researchers found that under-sink reverse osmosis and two-stage filters removed nearly all of the PFAS they tested for, while activated carbon filters in pitcher, countertop, refrigerator and faucet styles were inconsistent and unpredictable.

- Independent testConsumer Reports says three of the pitchers in its tests, the Brita Denali with Elite filter, the Culligan Zero Water ZD-012-RP and the ZeroWater Ready-Pour ZD-010RP, are certified to NSF standards to reduce lead, chlorine and PFAS. Consumer Reports ↗

- Stain, water or grease resistant treatments, which usually mean fluorinated chemistry.
- Whether the brand discloses what is in the product, or stays silent behind a “clean” claim.
- Independent lab results and certifications where they exist.
