PFAS score
Siemens · Air Fryers
Countertop Combi Oven with Air Fry & Steam
Lower concern. Combination ovens rarely use PFAS-prone coatings.
Siemens combi ovens use stainless steel and metal components with no known PFAS-containing nonstick or water-repellent coatings. Siemens provides no explicit PFAS disclosure, but the product design inherently avoids high-risk categories.

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.
