Nalgene Review, Is Nalgene Non-Toxic?
Nalgene averages 78 out of 100 on PFAS Authority's PFAS and toxin screen across the 12 Nalgene products graded as of October 2026, and all 12 reach its 70 point pass mark.
Nalgene grades Excellent on our four-band scale. On disclosure, the brand says nothing publicly about PFAS. See what every brand has published about PFAS for how that compares.
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.
