What is PFAS Free?
A PFAS molecule is defined, based on statements from the U.S. EPA and the most stringent, far-reaching PFAS definition passed in the state of Minnesota and Maine legislation, as any molecule which contains at least 1 fully fluorinated carbon atom.
Based on its unique molecular structure, BestSolv® Omega is PFAS free and does NOT contain a fully fluorinated carbon atom. The engineered fluid is based on Hydrochlorofluoroolefin HCFO / Hydrofluoroolefin (HFO) proprietary solvents which are understood as the next generation solvents beyond HFE and HFCs.
