Compare non-stick marketing claims to truly inert, PFAS-free cookware.

Most non-stick cookware is coated with PTFE (polytetrafluoroethylene), the chemical family behind Teflon. At high heat — typically above 260 °C / 500 °F — PTFE coatings begin to off-gas, releasing compounds linked to flu-like symptoms in humans and fatal toxicity in birds. For decades, PTFE was made using PFOA (C8), a persistent "forever chemical" now banned in most countries. Today's coatings use shorter-chain PFAS replacements like GenX — but independent research suggests these carry similar concerns. "PFOA-free" on a label does not mean PFAS-free.

Truly inert cookware avoids synthetic coatings altogether. Cast iron and carbon steel build a natural seasoning layer over time. 316 surgical stainless steel is non-reactive at cooking temperatures. Unglazed or food-safe enameled cast iron contains no coatings that can flake or off-gas. These materials have decades of documented safe use, whereas the full long-term profile of replacement PFAS chemistries remains under study.

Use the ratings below to quickly scan what we track in this category. Items rated Avoid contain materials with the most documented concerns. Best-rated items are those we'd reach for ourselves.

Key concerns

  • ✕PTFE / PFAS coatings
  • ✕PFOA replacements (GenX, C6 PFAS)
  • ✕Cadmium and lead in some glazed ceramics

Safer alternatives
