Ruffoni · Woks
Ruffoni Opus Prima Hammered Stainless-Steel Wok with Warming Stand, Silver
Lower PFAS concern, bare stainless steel wok with no non-stick or special coatings.
Ruffoni Opus Prima is hammered stainless steel with no non-stick surface, which means no Teflon-type coating, Teflon-family coating, or common PFAS coatings typical of non-stick cookware. Ruffoni makes no public PFAS claims, but the product's uncoated design eliminates the primary PFAS risk vector in cookware.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
