Does ZeroWater remove PFAS?
Last reviewed July 2026.
Yes — ZeroWater holds a certified PFOA/PFOS claim. Not marketing copy: an accredited certifier lists it, and you can look the listing up.
Model by model
| Model | Standards | PFOA/PFOS | Certifier | $ / certified gal |
|---|---|---|---|---|
| 5-Stage Replacement Filter (2-pack) ZR-002 buy ↗ | 42 53 | ✓ | IAPMO | $1.233 |
ZR-002: System certified by IAPMO R&T to NSF/ANSI 42 (chlorine) and 53 (lead, hexavalent chromium, PFOA/PFOS, mercury). Not in the NSF listing database — IAPMO is a separate accredited certifier.
A certification nerd's footnote: our ranking's "PFAS (401)" column tracks NSF/ANSI 401 — but PFOA/PFOS can also be certified inside an NSF/ANSI 53 claim set, which is exactly how ZeroWater's claim is listed (by IAPMO). Same verified claim, different standard number. This is why we read claim sets, not just standard numbers.
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.
