- Can home water filters remove PFAS?
A number of studies have been conducted to determine the efficiency of filtration devices, for point-of-use filters. The results of these studies have shown that point-of-use filters can remove trace organic compounds. Based on these studies, there currently are three general types of filtration systems that can potentially can reduce PFAS levels in water, if properly maintained: granulated activated carbon – either in refrigerator, faucet, or pitcher filters and some filtration systems installed on your water line; reverse osmosis; or granulated activated carbon used with reverse osmosis. However, it is important to ensure the systems are maintained according to the manufacturer and that your water is tested.

Reverse Osmosis Systems
A reverse osmosis system combined with a carbon filter is most effective at removing water contaminants.
Reverse Osmosis Systems
A reverse osmosis system combined with a carbon filter is most effective at removing water contaminants.
Laboratory test kits are the only way to test your water for PFAS. Whether you're purchasing them from a provider or receiving one from a public utility or health department, you will be collecting a sample of your water for analysis. Test strips cannot test for PFAS.
Does distilled water remove PFAS? ›The most obvious benefit of distillation for PFAS removal is its effectiveness. A water distiller offers one of the most effective ways to remove PFAS. While most water filters remove around 80% -90% PFAS, distillation removes more than 99% of this impurity — even down to the parts per trillion level.
Which bottled water does not have PFAS? ›Waiākea Hawaiian Volcanic Water has no PFAS in any of its products, including its sparkling and non-carbonated water. In fact, Waiākea is one of few bottled water brands to have no detectable (ND) levels of PFAS in its still or sparkling water.
Do whole house water filters remove PFAS? ›While many homes have whole-house water softening or iron filtration systems, sampling data indicate that those systems do NOT remove PFAS.
Do Brita filters remove PFAS? ›Despite its cost-effectiveness, EWG's testing revealed that the standard Brita filter only achieved a modest 66% reduction rate for PFAS in water.
Is it OK to shower in water with PFAS? ›It is safe to shower and bath in PFC/PFAS- contaminated water. However, bottled water is not tested for the presence of PFC/PFAS, so we don't know if PFC/PFAS may be present in these sources as well.
Does all tap water have PFAS? ›At least 45% of tap water in the U.S. is known to have PFAS in it, according to the U.S. Geological Survey. “We have been monitoring for PFAS for some time, and we see that it's occurring in drinking water systems at levels of concern,” said Fox.
How do I know if my drinking water has PFAS? ›If you're concerned about PFAS in your drinking water or you live near one of the contamination sites listed on our PFAS Exchange, find out if your water has been tested for PFAS by contacting your local water utility or your health department.

Filtering your water
“The water filters that are most effective for PFAS are reverse osmosis filters, which are more expensive, about in the $200 range,” Andrews said. Reverse osmosis filters can remove a wide range of contaminants, including dissolved solids, by forcing water through various filters.
If you know your tap water is contaminated, with PFAS or other compounds, experts say bottled water is the quickest solution to limit your exposure — at least for the short-term. The low-density plastic used for bottled water is not considered a potential source of PFAS contamination, experts say.
Do PVC pipes contain PFAS? ›Our research confirms that 100% of PVC is manufactured using either mercury, asbestos, and/or per- and polyfluoroalkyl substances (PFAS) in its supply chain.
Does refrigerator water have PFAS? ›Unfortunately, no. Refrigerator water filters reduce PFAS contaminants but do not remove them. These filters are designed to remove chlorine, taste, and odors from water. Consider a whole-home water filtration system if you're thinking about purchasing a water filter that removes PFAS from tap water.
Do all soda waters have PFAS? ›But that may not necessarily be the case. In 2020, Consumer Reports ran a study to determine PFAS levels in 47 bottled waters, including 35 noncarbonated and 12 carbonated samples. Many of the carbonated waters had PFAS in them.
Is rainwater unsafe to drink PFAS? ›According to new research, rainwater almost everywhere on Earth is considered unsafe to drink, due to the PFAS, also known as 'forever chemicals'. Forever chemicals are Per-and poly-fluoroalkyl substances (PFAS), a large family of human-made chemicals that don't occur in nature.
What is the most effective water filtration? ›Reverse Osmosis (RO)
Reverse osmosis filters are top of the line for removing a large percentage of contaminants from the water, potentially including dangerous bacteria associated with waterborne diseases. RO filters work by pushing water through the reverse osmosis membrane using pressure.
Taste test participants described Brita water as “most clean," “tasted pure," and “most neutral." However, the Brita water didn't win in a landslide. The Pur water was a close second, and testers commented that it tasted “clean and refreshing” and had “no aftertaste.”
What is the best water filter pitcher to remove contaminants? ›Waterdrop – Lucid 10-Cup Water Pitcher Filter System – PT-07
The Waterdrop Lucid 10-Cup Water Pitcher is our top pitcher filter, which reduces the presence of 19 contaminants including 97.4% of chlorine taste and odor, rust, magnesium, mercury, copper, and other contaminants to improve the quality of your tap water.
It's also more compact, taking up less room in your refrigerator, but holds the same 10 cups of water as the ZeroWater. The only benefit the ZeroWater has over the Brita is its ability to remove lead. If lead is a concern, and you don't mind the high cost of filter replacements, the ZeroWater may be a better choice.
