Aquasana water filters average Excellent on our four-band scale. 7 of the 7 we graded are worth buying. That is above 36% 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 Aquasana filters remove PFAS?

Yes. 9 Aquasana filters are certified to reduce PFOA and PFOS 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.
