LARQ 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 LARQ says and does about PFAS
LARQ makes specific, checkable PFAS claims about its filters, and they are not all the same level of proof. Its Advanced Under Sink Filter is listed by NSF for total PFAS reduction, and its Filter Straw is certified by IAPMO to the same NSF/ANSI 53 standard for PFOA and PFOS. Its Advanced Bottle Filter and Advanced Pitcher Filter are described as independently tested to that standard rather than certified. We found no LARQ statement on whether its bottle coatings or plastics contain PFAS.

Sources checked September 14, 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.
LARQ 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.
