What are PFAs?

Water Filter Effectiveness in Eliminating PFAs

PFAs or forever chemicals cause various health issues, from cancer to thyroid issues. According to EWG, PFAs contaminate drinking water for 110 million Americans. Drinking water isn’t the sole source of exposure to PFA but ranks top with other factors like cooking with eroding non-stick cookware.

Under the sink, RO and two-stage filters are the most effective, filtering about 90% of PFAs. Pitcher-style filters, faucet-mounted ion exchange resin, and refrigerator water filters have lower efficacy. Even worse is if they use carbon-activated filtration, which may increase PFA levels at some points of use. Carbon-activated filters remove about 73% of PFAs. Changing filters in the water filters improves efficacy.

Research shows that reverse osmosis water filters are the most effective in removing water contaminants, PFAs included. Closed-circuit RO reduced PFA levels to 2 ppt (the lowest detectable level). Large-scale municipal filters use carbon-activated filters since they are cheaper. You will want to install a reputable filter from Blue Heron Water to lower PFAs levels below the government advisory levels.
