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.
What Contigo says and does about PFAS
We found no PFAS statement from Contigo. Contigo's own support pages we could load address BPA and materials, not PFAS.
Sources checked September 30, 2026. A brand statement is the company’s own claim, which we report but have not verified. Our grades are model-based estimates, not lab tests.
