Garmin Review, Is Garmin Non-Toxic?
Across 15 graded products, Garmin averages Excellent (82/100). On disclosure, the brand says nothing publicly about PFAS. 14 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.

Garmin and PFAS, common questions
- Does Garmin have PFAS?
- We graded 15 Garmin products, averaging Excellent (82/100). 14 grade Good or better. Grades are model-based estimates built from published materials, ingredients and disclosures, not lab tests.
- Is Garmin non-toxic?
- Garmin Vivoactive 5 is the highest-graded Garmin product we have scored, at 85/100. It depends on the product line rather than the brand, so check the grade of the exact item you are buying.
- Which Garmin products are lower concern for PFAS?
- The highest-graded Garmin products we have scored are Garmin Vivoactive 5, Garmin CIRQA Accessory Bands, Garmin vivosmart 5 Bands. That is our model-based estimate from materials and public disclosure, not a lab test.
- Which Garmin products should I avoid?
- The lowest-graded Garmin products we have scored are Garmin QuickFit Band. Each one links to the evidence behind its grade.
