How Else Can I Limit My Exposure to PFAS?

Besides filtering your drinking water, there are several ways to decrease your overall exposure to PFAS.

Avoid Products Advertised as Nonstick or Stain- or Water-Resistant

These include stain-proof carpets, furniture, clothing, and outdoor gear. U.S. manufacturers are not required to notify shoppers when a product contains PFAS, so it can be tricky to find PFAS-free products.

 But a good rule of thumb is to stay away from products labeled “nonstick,” says Bell.

The same goes for cookware. If the label says “Teflon,” it could expose you to PFAS. Alternative cookware options include cast iron, stainless steel, aluminum, and ceramic pots and pans.

“I tell folks to throw away their nonstick pans, because even if it’s not PFOA or PFOS, there are other PFAS chemicals in there,” Anderko says. “The science is not out yet on those newer chemicals.”

Pass on Foods Packaged in Nonstick Wrappers and Containers

Some PFAS that coat packaging can leach into food. “A lot of takeout containers and bakery bags have this coating to keep the grease from leaking,” says Anderko, adding that food-labeling laws address the contents of food, not packaging.

“Unless PFAS were used in the food product, then they don’t need to list it,” she says. “Better for your heart and better for the rest of your body not to eat as much fried, greasy food with packaging containing PFAS.”

Steer Clear of Products That Have ‘Fluoro,’ ‘Polytetrafluoroethylene,’ or ‘Teflon’ Listed as Ingredients

Products that may contain these ingredients include lipsticks, makeup powders, and personal care products such as dental floss and shampoo. The Environmental Working Group has a database that tracks thousands of personal-care items that contain PFAS and other toxic ingredients.

Get Your Water Tested

The Environmental Protection Agency (EPA) requires most public water providers to test for PFAS. If your home is connected to a public water system, contact your local water utility and request recent test results. If you have a private well, you can have your water tested by a private lab.

Be Careful Where You Fish

Fish are a product of the water they live in, and many lakes and streams carry pollutants. Fish take in these contaminants, storing them in their fat and muscle tissues. Many states and municipalities publish information about contaminated fish, where they are, and how much is safe to consume. Historically, fish pollutants have included PCBs and mercury, but PFAS are being detected more often.
