Does Cosori air fryers have PFAS?
PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
We graded 10 Cosori air fryers products, averaging Bad (21/100). 1 of them grades Good or better. Against the other 29 air fryers brands we grade, where the middle brand sits at 15/100, Cosori is better than typical, scoring above 79% of them.
