Does Clearly Filtered remove lead?
Last reviewed July 2026.
Clearly Filtered says yes. The public listings say: not certified. Clearly Filtered advertises lead reduction backed by independent lab reports, and the reports may well be real. But we checked the accredited certifiers — NSF, WQA and IAPMO — and there is no listing (July 2026). "Tested to NSF/ANSI 53" is a lab result on a sample the brand chose; certified to 53 means ongoing audits and a public record. Only one of those can you verify yourself.
Model by model
| Model | Standards | Lead (53) | Certifier | $ / certified gal |
|---|---|---|---|---|
| Clearly Filtered Water Pitcher CF-Pitcher brand ↗ | — | ✗ | none | — |
CF-Pitcher: Not found in the NSF certified listing database (checked 2026-07-13). Clearly Filtered advertises testing to NSF/ANSI protocols by independent labs, which is not the same as being certified by an accredited certifier (NSF, WQA or IAPMO) with ongoing audits.
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.
