Our take
Berkey systems are gravity-fed stainless steel containers with replaceable Black Berkey filter elements. The brand's published filter-life specification is approximately 6,000 gallons per pair of elements — substantially longer than typical pitcher cartridges. Berkey's published lab reports document reduction across heavy metals, pharmaceutical residues, and some PFAS compounds. Important editorial caveat: Berkey publishes its own commissioned independent lab testing rather than carrying an active NSF/ANSI P473 certification, so the citation tier is "manufacturer-commissioned independent testing" rather than NSF certification — readers tracking certification specifically should weigh that distinction.
