How to Remove PFAs from Water in your House

PFAs are present in 99% of people tested. This article talks about their prevalence and how to remove PFAs from water in your house.

PFAS, or perfluoroalkyl and polyfluoroalkyl substances were invented in the 1950s. They are used in products like non-stick pans and stain or water resistant carpeting or furniture. Now they are everywhere. I recently learned that they are present in the Glide floss I am using. We take in PFAs through eating and drinking and contact with products…like floss.

Here’s the best article I’ve found that talks about the research being done: 

  • ” Within 30 years, they were everywhere: in non-stick pans, raincoats, food wrappings, fire-fighting foams and all kinds of stain-proof coatings. Chemists would later call this fluorinated family ‘per- and poly-fluoroalkyl substances’, or PFASs. Their carbon–fluorine bonds are among the strongest known in nature — so the molecules don’t degrade.”
  • “A class action lawsuit against DuPont led to some of the first research on the effect of PFAs and C8, a variation. The result was an epidemiological study of almost 70,000 people which, by 2012, had linked C8 to diseases including kidney and testicular cancers, pregnancy-induced hypertension, ulcerative colitis and high cholesterol (see”

Most likely you have PFAs in your body.

Even more alarming your children have most likely been exposed to PFA. This can affect their health throughout their entire lives.

According to a 2017 review of 64 studies on children and PFAS concluded that scientists are learning that childhood exposure during developmental periods may negatively impact a person’s lifelong health. They concluded that this is true “even at doses that have little effect in adults.”

PFAs can be present in your drinking water. And they may not be listed on your water report. Sadly, a new individual has been put in charge of drinking water at USEPA who believes that PFAs are not a concern. This means that nothing will be done about PFAs in water for at least the next two years, maybe longer.

Your best bet is to protect yourself. To remove PFAs from your water, then I would suggest a combination of a whole house water filter plus reverse osmosis for drinking. The whole house filter will reduce or remove them and the reverse osmosis will remove anything that gets past the filter. Here is an article that talks about how to remove PFAs from drinking water:

It appears that there are no good mechanisms for ridding the body of PFAs.

If you can eliminate your intake of PFAs then research suggests the amount in your body would naturally reduce by about half over four years. But that could be a challenge. There are now many, many products that use PFAs. You have to eliminate those and then be proactive about detoxing your body. I couldn’t find any specific detox recommendations. However, one study suggests this:

The liver is the main organ of detoxification, so supporting it with the nutrients that it uses up in the detox process is a positive step. Lipoic acid, vitamin C, glutathione, and its precursor NAC are all a good place to start. Basically he’s suggesting you take supplements that support liver function.

PFAs, including PFOAs and PFOS, are not going away anytime soon. And they are already in products in your home. I thought I was living pretty clean until I found out it’s in the floss I use. PFAs are in 99% of people tested. If you want to remove PFAs from your water I suggest a combination of whole house water filter plus reverse osmosis at the kitchen sink. If you’re on a budget, then I’d use the reverse osmosis system. I like the redundancy of whole house and reverse osmosis.
