Calphalon Signature Nonstick Cookware Set
Skip until Calphalon discloses coating chemistry; nonstick cookware typically uses Teflon-type coating-based coatings that may contain PFAS.
Calphalon does not publicly disclose the chemical composition of the Signature nonstick coating. Most nonstick cookware relies on Teflon-type coating (polytetrafluoroethylene) or similar Teflon-family coating historically formulated with PFAS.
Still want this one anyway? Check the price on Amazon. We’d swap it.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
