What Cosori says and does about PFAS
Cosori publishes an explainer saying PFAS-free, PFOA-free, PTFE and Teflon do not all mean the same thing, and that a PFAS-free claim usually refers to a specific material or coating the manufacturer identifies. On that page it does not identify one for any of its own air fryers. We found no Cosori statement naming what the baskets we grade are coated with.
