Is Berkey NSF certified?
Last reviewed July 2026.
Certified, yes — but not for lead. Berkey appears in the public certified listings (NSF), which is real. But the certification covers NSF/ANSI 42 only: chlorine, taste and odour. There is no NSF/ANSI 53 listing, and 53 is the standard that covers lead and the other health-effect contaminants. A filter can be genuinely certified and still carry no certified lead claim. This is one of them.

| Model | Standards | Lead (53) | Certified capacity | $ / certified gallon |
|---|---|---|---|---|
| Big Berkey / Royal Berkey / Travel Berkey (Phoenix element) Phoenix Gravity New Millennium Edition Amazon ↗ | 42 | ✗ | — | price pending |
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 those standard numbers mean
- NSF/ANSI 42 — aesthetic effects (chlorine, taste and odour). Not a health claim.
Verify it yourself: every Berkey row above links the certifier's own listing. If a number here disagrees with the listing, the listing wins — tell us and we'll fix it.
What does have a certified lead 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 NSF/ANSI 53 with an accredited certifier, and the listing is public.
