Do Waterdrop water filters have PFAS?
Waterdrop water filters average 95 out of 100 on PFAS Authority's PFAS and toxin screen across the 29 Waterdrop water filters graded as of October 2026, level with the 95 out of 100 median for the 64 other water filters brands graded alongside it.
Waterdrop water filters average Excellent on our four-band scale. 28 of the 29 we graded are worth buying. That is above 37% of the water filters brands we grade.
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.
Do Waterdrop filters remove PFAS?
Yes. 3 Waterdrop filters are certified to reduce total PFAS under NSF/ANSI 53.
This is a separate question from the grade above, which is about what the filter is made of. A certification means a certifier tested one specific claim on one specific model, so it covers the models named here and nothing else in the range.

What Waterdrop says and does about PFAS
We found no PFAS statement from Waterdrop about the materials in its own filters. Waterdrop says some of its reverse osmosis systems reduce PFOS and PFOA in tap water, which is a claim about filtering and not about what the products are made of. We found no lab test or lawsuit naming Waterdrop for PFAS.
