PFAS score
Zwilling J.A. Henckels · Woks
ZWILLING Joy Plus 12-Inch Stainless Steel Nonstick Wok with Lid
Skip until coating transparency improves; PFAS risk unclear for this nonstick wok.
Zwilling does not disclose the composition of this wok's nonstick coating, making PFAS exposure impossible to rule out. Standard industry nonstick cookware often uses Teflon-type coating or Teflon-family coating unless explicitly stated otherwise. No third-party PFAS testing or claims from the brand reduce concern here.

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.
