Does Brita remove PFAS?

Last reviewed July 2026.

No. Certified — but not for PFOA/PFOS. Brita'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

OB06: Neither WQA's NSF/ANSI 53 claim set for the OB06 (asbestos, benzene, cadmium, lead, mercury) nor its NSF/ANSI 401 claim set (BPA, estrone, ibuprofen, microplastics, naproxen, nonylphenol) lists PFOA or PFOS, and Brita's OB06 performance data sheet has no PFOA/PFOS line. Source: WQA Gold Seal listing, Brita LP, read 2026-10-02.

OB03: The OB03 data sheet lists no PFOA or PFOS claim, under NSF/ANSI 53 or any other standard. Source: Brita Standard (OB03) performance data sheet, read 2026-10-02.

OB06: WQA Gold Seal certified to NSF/ANSI 42, 53 and 401. Brita's US pitcher filters are certified by WQA, not NSF — they do not appear in the NSF listing database.

OB03: Brita's OB03 performance data sheet (read 2026-10-02) says WQA certifies it to NSF/ANSI 42 (chlorine, zinc) and NSF/ANSI 53, but its 53 claims are cadmium, copper and mercury only. Lead is not one of them, so the OB03 makes no certified lead claim despite holding 53. A WQA directory search for OB03 on the same day showed only an NSF/ANSI 42 entry. Brita's US pitcher filters are certified by WQA, not NSF, so they do not appear in the NSF listing database.

Why NSF/ANSI 401 doesn't answer this: OB06 holds NSF/ANSI 401, and it is easy to read that as a PFAS certification. It isn't: the 401 claim sets list pharmaceuticals, BPA and similar compounds, and PFOA/PFOS is not among them. This is why we read claim sets, not standard numbers.

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. Brita's certifications are held by WQA, 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.
