Does Berkey remove PFAS?

Last reviewed July 2026.

No. Certified — but not for PFAS. Berkey's certification is real, but it does not include NSF/ANSI 401 or any PFOA/PFOS claim. Whatever the retail listing implies, there is no certified PFAS reduction here.

Model by model

Phoenix Gravity New Millennium Edition: Listed under New Millennium Concepts Ltd to NSF/ANSI 42 ONLY — chlorine reduction and taste/odor. There is no NSF/ANSI 53 listing, so there is no certified lead or health claim. The widely-sold Black Berkey element is not listed at all; the certification attaches to the newer Phoenix element.

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. Berkey'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 — 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.
