Does Clearly Filtered remove PFAS?

Last reviewed July 2026.

Clearly Filtered advertises PFAS reduction. There is no certified claim behind it. We checked NSF, WQA and IAPMO (July 2026): no listing. Independent lab reports are not nothing — but they are a one-time result on a sample the brand chose, not a certification with ongoing audits and a public record.

Model by model

CF-Pitcher: Not found in the NSF certified listing database (checked 2026-07-13). Clearly Filtered advertises testing to NSF/ANSI protocols by independent labs, which is not the same as being certified by an accredited certifier (NSF, WQA or IAPMO) with ongoing audits.

What does have a certified PFOA/PFOS claim

Ranked by cost per certified gallon — the only fair way to compare a $20 pitcher filter with a $50 fridge cartridge. Every one below holds a certified PFOA/PFOS claim with an accredited certifier, and the listing is public.

How to check this yourself

The absence is the finding, and absence is checkable. Search the three accredited certifiers' public databases — NSF International, WQA and IAPMO R&T — for Clearly Filtered and for the model number printed on the filter itself. Nothing comes back. That is not us failing to find it: a certified product is listed by the body that certified it, and an unlisted product is an uncertified one.

What you will find instead is Clearly Filtered's own test reports. Read who commissioned them, which single sample was tested, and whether any accredited body audits the factory afterwards. A one-off lab result and an ongoing certification are different things wearing similar words.

If a figure on this page disagrees with the certifier's listing, the listing wins. Tell us and we will correct it.

What "removes PFAS" actually covers

The certified claim is PFOA/PFOS reduction — the two legacy compounds the standards test for — not "all PFAS", a family of thousands of chemicals. A certified filter is still the strongest verifiable option a pitcher or fridge filter can offer; just read the claim as written. Standards background: 42 vs 53 vs 401.

We do not test filters — we index what accredited certifiers publish, with attribution, and make no health or treatment claims. A certification covers a specific model against a specific standard; it is not a general seal of quality. We are not affiliated with NSF International.
