What are PFAS?

PFAS are a class of man-made chemicals that don’t break down, are stable in water, and remain in the environment and in the human body for long periods of time, earning them the nickname “forever chemicals.” According to the Agency for Toxic Substances and Disease Registry (ATSDR), it can take up to four years for levels of PFAS in the human body to reduce by half.

PFAS have been incorporated into a wide range of products and industries, including non-stick cookware, water-resistant clothing, stain-resistant fabrics, and fire-fighting foam. There are nearly 5,000 different types of PFAS, with perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) being the most prevalent and extensively researched. While U.S. manufacturers ceased production of PFOA and PFOS in the early 2000s, their long-lasting presence and continued use abroad mean that PFAS remain abundant in our environment.

How to remove PFAS from water?

PFAS can be removed from water through reverse osmosis, activated carbon filtration, and ion exchange. 

Does boiling water remove PFAS?

No, boiling water does not remove PFAS. In fact, heat does not break down PFAS, and instead concentrates the chemicals and renders them more dangerous if ingested.
