Every ranking aggregates published, checkable sources - never our own lab work, because we don’t do lab work. The inputs, roughly in order of weight:
- Construction. Uncoated cookware (stainless, cast iron, carbon steel, bare titanium) has no nonstick coating to contain PFAS. That is a physical fact about the product, not a claim to trust, so it ranks above any coating promise.
- Independent testing.Published third-party test results, attributed by name to whoever ran them, with what exactly was tested. We never rebrand someone else’s testing as our own.
- Regulation.State PFAS laws - Minnesota’s ban on intentionally added PFAS in cookware (effective 2025) and the states following it - give a hard compliance signal brands must answer to.
- Brand disclosures. Materials pages, published lab reports, and compliance statements from the brands themselves - always labeled as self-reported.
- Price.Checked against the merchant on the date shown on each page, because “safest” without “at what price” is half an answer.
