PFAS score
WMF · Pressure Cookers
Perfect Pressure cooker 4,5 l stainless steel
Lower-concern cookware; stainless steel doesn't require PFAS, but WMF has not publicly disclosed PFAS testing.
WMF's 4.5L stainless-steel pressure cooker is made from materials (stainless steel, likely stainless interior) that do not inherently require PFAS coatings. However, WMF has not made public PFAS-free claims or third-party certifications. No lab data or recalls are on record.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
