3M Review, Is 3M Non-Toxic?
Across 14 graded products, 3M averages Good (71/100). On disclosure, the brand says nothing publicly about PFAS. 8 of its products grade Good or better. Grades are model-based estimates, not lab results.
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.
