Compostable Coffee Review, Is Compostable Coffee 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 3 graded products, Compostable Coffee averages Poor (27/100). On disclosure, the brand says nothing publicly about PFAS. None of its products grade Good or better yet. Grades are model-based estimates, not lab results.

Graded and flagged Poor and Bad, we’d swap these
