What to watch for in refrigerator filters
Beyond the PFAS grade, these are the things our graders recorded on the 15 refrigerator 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.
Found on 1 of these refrigerator filters. Plausible but unconfirmed on 3 more, meaning nobody has ruled it out. EPA
- VOCs and off-gassing
Volatile compounds that evaporate out of a material at room temperature, which is what a new product smell is.
Plausible but unconfirmed on 1 more, meaning nobody has ruled it out. EPA
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 refrigerator 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. Duke University via EurekAlert! ↗
- 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 ↗

What we check on refrigerator filters
- Confirmed PFAS, PTFE or fluoropolymer content, which is the heaviest penalty we apply.
- 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.
