Weber Review, Is Weber Non-Toxic?
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.
Across 6 graded products, Weber averages Good (52/100). On disclosure, the brand says nothing publicly about PFAS. 1 of its products grade Good or better. Grades are model-based estimates, not lab results.
Worth buying from Weber Good or better, safest first
