PFAS (Per- and Polyfluoroalkyl Substances)

What are PFAS?

PFAS stands for per- and polyfluoroalkyl substances. It is a large group of thousands of man-made chemicals. These chemicals have unique properties that make them resistant to heat, water, and stains.

PFAS are often called “forever chemicals” because they don’t break down easily in humans or the environment, and they can accumulate over time in water, soil, and people.

Where are PFAS found?

Because of their durability and resistance properties, PFAS have been widely used in consumer products and industrial applications since the 1940s. Common sources include:

  • non-stick cookware
  • water or sweatproof clothing
  • stain-resistant carpets and upholstery
  • water-proofing sprays
  • grease-proof food packaging
  • cosmetics and personal care products

PFAS contamination has also been discovered in drinking water in some communities.

Health impacts of PFAS

Research has shown that PFAS exposure may negatively impact your health. This can include liver and kidney damage, immune system suppression, decreased vaccine response, developmental disorders, and cancer.

How can I protect my family?

How to avoid PFAS in everyday products:

  • Avoid products with “fluoro” ingredients listed on the label.
  • Choose cookware without non-stick coatings, such as cast iron, stainless steel, or ceramic.
  • Avoid cosmetics with PTFE (polytetrafluoroethylene), perfluorooctyl triethoxysilane, perfluorononyl dimethicone, perfluorodecalin, and perfluorohexane.
  • Eat more fresh food to avoid takeout & other food packaging with grease-resistant coatings.
  • Use granulated active carbon (GAC) filters and/or reverse osmosis (RO) filters for your drinking water.
