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.
