Quick Take
Score: 4.5/10 | Black Berkey elements inherit all concerns about the Berkey product line: zero NSF certifications, self-funded testing only, state sales ban, and EPA warning letters. Premium pricing for unverified performance.

The Black Berkey elements are replacement filters for Berkey gravity systems. Like all Berkey products, they hold NO NSF certifications and rely entirely on self-funded testing. The Iowa sales ban and EPA warning letters regarding unsubstantiated claims apply to these elements.
