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
| Model | Standards | PFOA/PFOS | Certifier | $ / certified gal |
|---|---|---|---|---|
| Big Berkey / Royal Berkey / Travel Berkey (Phoenix element) Phoenix Gravity New Millennium Edition brand ↗ | 42 | ✗ | NSF | — |
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 "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.
