PFAS score
Big Berkey · Pitcher Water Filters & Cartridges
Big Berkey Gravity-Fed Stainless Steel Countertop Water Filter System 2.25 Gallon with 2 Authentic Black Berkey Elements BB9-2 Filters
Lower PFAS concern for the vessel itself; filter element composition opacity prevents high confidence.
Big Berkey's stainless steel housing poses minimal PFAS risk, and gravity-fed carbon filtration typically does not introduce PFAS. However, the brand discloses nothing about PFAS in their Black Berkey filter media formulation, proprietary carbon blends sometimes contain fluorinated compounds or PFAS-adjacent additives.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
