Pentair Review, Is Pentair Non-Toxic?
Pentair averages 95 out of 100 on PFAS Authority's PFAS and toxin screen across the 3 Pentair products graded as of October 2026, and all 3 reach its 70 point pass mark.
Pentair grades Excellent on our four-band scale. On disclosure, the brand says nothing publicly about PFAS. See what every brand has published about PFAS for how that compares.
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 Pentair told Minnesota 9 filings, the company’s own words to a regulator
Minnesota requires manufacturers to report every product they sell there that contains intentionally added PFAS, naming the compound, what it does and roughly how much.

Source, manufacturer filings made to the Minnesota Pollution Control Agency under the state’s PFAS in Products law and published through PRISM, run by the Interstate Chemicals Clearinghouse. These are the manufacturers’ own statements, not our grades and not laboratory results. A filing covers the product as sold in Minnesota and says nothing about products or formulations the company did not file. Reporting was still open when this was pulled, so absence from the set is not evidence a product is PFAS-free.

- Does Pentair have PFAS?
- Pentair averages 95 out of 100 on PFAS Authority's PFAS and toxin screen across the 3 Pentair products graded as of October 2026, and all 3 reach its 70 point pass mark. Grades are model-based estimates built from published materials, ingredients and disclosures, not lab tests.

- Pentair 3/4" Inlet 5 gpm Whole House Water Filter System U25-S-S18 is the highest-graded Pentair product we have scored, at 95/100. It depends on the product line rather than the brand, so check the grade of the exact item you are buying.
- Which Pentair products are lower concern for PFAS?
- The highest-graded Pentair products we have scored are Pentair 3/4" Inlet 5 gpm Whole House Water Filter System U25-S-S18, Pentair Everpure FXI-22 FX Water Filtration System, Pentair OMNIFilter Whole House Filter System.
