Biotrem Review, Is Biotrem 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 5 graded products, Biotrem averages Poor (34/100). 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 Biotrem Good or better, safest first
