Does Clearly Filtered remove PFAS?

Last reviewed July 2026.

No. Certified — but not for PFOA/PFOS. Clearly Filtered's certification is real, but no certifier's claim set for the models we track lists PFOA or PFOS reduction — not under NSF/ANSI 53, and not under NSF/ANSI 401, which on the listings we read covers pharmaceuticals and other emerging compounds instead. Whatever the retail listing implies, there is no certified PFAS reduction here.

Model by model

CF-Pitcher: NSF lists the pitcher under NSF/ANSI 42 only. Clearly Filtered's PFAS claim rests on independent lab reports, not a certification. Source: NSF listing, Clearly Filtered, read 2026-09-27.

CF-Pitcher: NSF lists Clearly Filtered's "Filtered Water Pitcher" (and its "Pitcher Replacement Filter") under NSF/ANSI 42 for chlorine reduction and taste and odour reduction, 100 gallons, and to NSF/ANSI/CAN 372 for lead-free materials (NSF listing, company search, read 2026-09-27). There is no NSF/ANSI 53 or 401 listing, so its lead, PFAS and fluoride reduction claims rest on independent lab reports, not on an accredited certification. A trade-name search of the same database returns nothing, which is why a check on 2026-07-13 recorded it as not listed.

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

Nothing here needs to be taken on trust. Clearly Filtered's certifications are held by NSF, and each keeps a public database you can search by brand or model number. Look up the model printed on the filter — not the box, not the retail listing — and read which standards the entry lists. A model certified to 42 only will say exactly that.

What "removes PFAS" actually covers

The certified claim is PFOA/PFOS reduction — the two legacy compounds the standards test for — or, on newer NSF/ANSI 53 listings, a total PFAS claim tested on a set mixture of seven compounds that includes PFOA and PFOS. Neither is "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.
