PUR averages 95 out of 100 on PFAS Authority's PFAS and toxin screen across the 23 PUR products graded as of October 2026, and all 23 reach its 70 point pass mark. Grades are model-based estimates built from published materials, ingredients and disclosures, not lab tests. PUR states that its PUR PLUS pitcher filter PPF951K is certified by IAPMO under NSF/ANSI 53 to reduce 99.75 percent of Total PFAS, a mixture of seven compounds. Its cheaper PPF900Z filter is listed as Not Certified for Total PFAS on the same sheet, so which filter you buy changes the answer.

Pura Sport 18oz Bottle is the highest-graded PUR product we have scored, at 100/100. It depends on the product line rather than the brand, so check the grade of the exact item you are buying.

What PUR says and does about PFAS

PUR makes the strongest certified PFAS removal claim of the four big filter brands we grade. Its PUR PLUS pitcher filter PPF951K is certified by IAPMO under NSF/ANSI 53 for 99.75 percent reduction of Total PFAS, a seven compound test mixture. On the same performance sheet its cheaper basic filter PPF900Z is marked Not Certified for Total PFAS, so the claim does not carry across the range.

Brand statementPUR’s performance data sheet claims 99.75 percent reduction of Total PFAS for the PUR PLUS filter PPF951K, and marks the basic PUR filter PPF900Z as Not Certified in the same row. PUR ↗
Brand statementPUR defines its Total PFAS test mixture as PFOA, PFOS, PFHxS, PFNA, PFHpA, PFBS and PFDA. A Total PFAS claim covers those seven compounds, not every PFAS. PUR ↗
Brand statementPUR attributes the certification to IAPMO R&T under NSF/ANSI 42, 53 and 401, naming a certifier rather than relying on its own lab. PUR ↗
Brand statementAn older PUR pitcher performance sheet still published on pur.com covers the same two filter models and contains no PFOA, PFOS or PFAS line at all, which dates the PFAS claim to a recent revision. PUR ↗
Brand statementPUR also markets its PUR PLUS faucet filter as certified to reduce Total PFAS, although that product page names no certifier and no standard number. PUR ↗
Government sourcePennsylvania’s Department of Environmental Protection explains that when a product is certified under NSF/ANSI 53 for PFOA and PFOS, the acceptance level is 20 parts per trillion for both, so a certification is a threshold rather than complete removal.
