Does PUR remove lead?
Last reviewed July 2026.
Yes — and it's certified, not just claimed. Every PUR filter we track holds NSF/ANSI 53, the health-effects standard where lead lives, from an accredited certifier. That means the lead claim is in a public listing you can check — not just on the box.
Model by model
| Model | Standards | Lead (53) | Certifier | $ / certified gal |
|---|---|---|---|---|
| PLUS Pitcher & Dispenser Replacement Filter PPF951K1 buy ↗ | 42 53 401 | ✓ | NSF | $0.375 |
PPF951K1: Listed with NSF to NSF/ANSI 42 and 53; PUR also cites WQA certification for its lead claim. PUR is the most extensively NSF-listed pitcher brand in the database.
Why 53 is the number that matters
NSF/ANSI 42 is aesthetics — chlorine, taste, odour. 53 is health effects, and it is where the lead claim lives. A filter can be honestly "NSF certified" and still filter nothing but taste — see 42 vs 53 vs 401.

We do not test filters — we index what accredited certifiers publish, with attribution, and make no health or treatment claims. A certification covers a specific model against a specific standard; it is not a general seal of quality. We are not affiliated with NSF International.
