Other companies that have filed

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.
