Contigo Review, Is Contigo Non-Toxic?
Contigo averages 78 out of 100 on PFAS Authority's PFAS and toxin screen across the 30 Contigo products graded as of October 2026, and all 30 reach its 70 point pass mark.
Contigo grades Excellent on our four-band scale.
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.
Contigo is one of the brands we researched by hand for our record of what every brand has published about PFAS, where the same question is answered for each of them in one line.
