Per- and polyfluoroalkyl substances, or PFAS, are synthetic chemicals that have found their way into countless aspects of our daily lives. These invisible adversaries pose a severe risk to human health and the environment. In this article, we will delve into what PFAS are and why they are so dangerous, emphasizing the importance of avoiding them. We will also provide 15 practical tips on how to avoid PFAS and protect your health.

What is PFAS?
PFAS, short for per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been in use since the mid-20th century. They are notable for their remarkable resistance to heat, water, and oil, making them highly effective in a wide range of industrial and consumer applications. These chemicals are pervasive in our environment, with two of the most infamous PFAS compounds being perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS).
However, don’t believe that simply buying something that is PFOA-free or PFOS-free will protect you. Sadly, these are well-known marketing tactics meant to deceive you into believing you are purchasing a healthier option. PFOA and PFOS are only 2 chemicals in the thousands of chemicals in the PFAS family. If you really want to avoid PFAS, look for companies that specify that their products are PFAS-free, not just PFOA-free or PFOS-free.
Why do I need to avoid PFAS?
The dangers associated with PFAS cannot be understated. These chemicals have been linked to a plethora of adverse health effects, and research continues to uncover their harmful implications:
- Risk of Cancer: Long-term exposure to PFAS has been linked to an increased risk of various cancers, including kidney and testicular cancer.
- Developmental Issues: PFAS exposure during pregnancy can lead to low birth weight, developmental delays, and other reproductive problems.
- Immune System Suppression: These chemicals can compromise the immune system’s ability to ward off diseases.
- Liver Damage: PFOA and PFOS can accumulate in the liver, potentially causing severe damage.
- Hormonal Disruption: PFAS may disrupt hormonal balances, leading to thyroid problems, decreased fertility, and other hormonal disorders.
Avoiding PFAS is not just a matter of personal well-being but also a collective responsibility to protect our environment, our children and all future generations.
15 Ways to avoid PFAS
So how do you avoid something that is already so pervasive in our environment? Don’t feel defeated. There are actually many things you can do to limit you and your family’s exposure to PFAS:
#1 Filter your water
Invest in a reputable water filtration system equipped to remove PFAS contaminants from your tap water. These filters typically use activated carbon or reverse osmosis technology. You can read our article on some of our favorite reverse osmosis water filters for your home. Here are some of our top picks (pictures are links):
#2 Throw out your nonstick cookware
Discard your nonstick pots and pans, often coated with PFAS, and opt for safer alternatives such as stainless steel, cast iron, or ceramic cookware. Check out our article on safer cookware for your kitchen for the full story. These are some of our favorite PFAS-free cookware options (pictures are links):
#3 Don’t heat up your food in plastic containers
When reheating food, avoid using plastic containers, which can release PFAS when exposed to heat. Instead, select microwave-safe glass or ceramic containers to prevent PFAS contamination in your meals. These would be better options (pictures are links):
#4 Avoid wrinkle-resistant, stain-resistant and waterproof fabrics
Steer clear of clothing labeled as “wrinkle-resistant,” “stain-resistant,” or “waterproof” as they often contain PFAS. Opt for garments made from natural fibers like cotton, linen, or wool. Not only are these materials free from PFAS, but they also allow your skin to breathe.
#5 Bring your own beverage cup
You’re getting a lot more than just coffee in that morning Starbucks trip, and it ain’t good. All disposable cups have a plastic lining in them that often contains PFAS compounds. What’s worse is that heat activates these chemicals even more. So next time you’re at the coffee shop, ditch disposable cups and bring your own reusable beverage container like a stainless steel beverage cup or a glass tumbler.
#6 Bring your own to-go container
To-go containers also have PFAS coatings. While some specific compounds have already been banned for use in to-go containers, other chemicals in the PFAS family are being used instead. Avoid it altogether. Bring your own glass to-go container instead.
#7 Avoid fast fashion
Fast fashion often relies on PFAS-based treatments for clothing. Make sustainable fashion choices by investing in quality and timeless pieces.
#8 Buy natural fiber clothing (cotton, linen, wool)
Beyond avoiding PFAS-treated fabrics, seek out natural fibers like cotton, linen, or wool. These materials are free from synthetic chemicals and are more comfortable against your skin.
#9 Buy PFAS-free dental floss
When purchasing dental floss, specifically look for products that proudly state they are PFAS-free floss. Keep an eye out for any mention of “PTFE” in the ingredients, a clear indicator of PFAS presence.
#10 Don’t pop your popcorn in the microwave
Microwave popcorn bags often contain PFAS, and the chemicals can leach into your popcorn during heating. Opt for stovetop-popped popcorn in PFAS-free cookware.
#11 Don’t upgrade to the stain-fighting coating on your new couch
When choosing furniture, refrain from upgrading to options with stain-resistant coatings. Go for furniture without these treatments to reduce your exposure to PFAS.
#12 Look for PTFE in the ingredients list
While a lot of the PFAS in our environment might come from contamination, there are still a ton of products that intentionally add PFAS to their ingredients list. Avoid products that list “PTFE” in their ingredients list.
#13 Use natural home cleaning solutions
Swap out conventional cleaning products for natural and PFAS-free alternatives. Many household cleaning agents can be replaced with safe, environmentally-friendly solutions such as vinegar, baking soda, or eco-friendly cleaning products, or our favorite… Branch Basics! Use our link for $10 OFF!
#14 Cut back on the fish
While fish can be a healthy part of your diet, some fish from contaminated water sources may accumulate PFAS. It’s no longer just mercury that you need to be cautious about, it’s also the PFAS! Be mindful of where your fish comes from and consider limiting consumption of fish from potentially polluted areas.
#15 Check your cosmetics
Carefully inspect the ingredients in your cosmetics and personal care products. Seek out PFAS-free alternatives, as certain cosmetics may contain these harmful chemicals, especially those advertised as “waterproof”. Your skin is your largest organ, and what you apply to it matters.
Avoid PFAS for a healthier world
PFAS represent a significant threat to our health and environment. Understanding the risks associated with these chemicals and taking proactive steps to avoid them is essential for our well-being and the preservation of the planet. By making informed choices, we can reduce our exposure to PFAS and contribute to a healthier, PFAS-free world.
