Do PUR water filters have PFAS?
PUR water filters average 95 out of 100 on PFAS Authority's PFAS and toxin screen across the 21 PUR 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.
PUR water filters average Excellent on our four-band scale. 21 of the 21 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 PUR filters remove PFAS?
Yes. 4 PUR 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 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.
