There are lists of companies which are PFAS-free -- or at least are in the process of becoming so, experts say. The Environmental Working Group has curated a list of companies who have not intentionally added PFAS to their products.
Consumers can also check the list of GreenScreen Certified products, which is a "globally recognized tool designed to assess and benchmark chemicals based on hazard," said Shari Franjevic, the GreenScreen program manager for Clean Production Action, an organization dedicated to assessing green chemicals, sustainable materials and environmentally preferable products.
"The key value of GreenScreen is that it takes really complex toxicology and distills it down to a score between one and four in harm (with four being the safest). That allows people to place chemicals on a continuum and say, 'OK, this is safer than that,' and begin to select safer chemicals for their products."
