Calphalon Signature Hard-Anodized Nonstick Wok
Skip, Teflon-type coating nonstick cookware carries inherent PFAS risk; safer alternatives exist.
Calphalon Signature uses traditional Teflon-type coating (Teflon) nonstick coating, a Teflon-family coating known to contain or leach PFAS. The brand makes no PFAS-free claim or third-party verification. Hard-anodized aluminum body is durable, but the nonstick layer remains a concern for chemical exposure, especially if overheated.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
