Not all types of in-home water filters completely get rid of toxic PFAS-News-The Fayetteville Observer-Fayetteville,NC <br /> Greg Barnes <br /> Wednesday <br /> Feb 5, 2020 at 6:54 PM <br /> A new study finds that under-the-sink reverse osmosis systems work best at removing "forever chemicals," but they <br /> aren't cheap. <br /> Not all types of in-home filters are completely effective at removing "forever chemicals" from drinking water, and a few <br /> could do more harm than good if not properly maintained, according to a new study released Wednesday by North <br /> Carolina researchers. <br /> Water filters in refrigerators,pitcher-style filters,under the sink reverse osmosis systems and whole-house filtration <br /> systems can function differently and have vastly different price tags, according to the study, headed by the researchers <br /> from Duke University and N.C. State University. <br /> Researchers tested 76 drinking water filtration systems to determine their ability to remove toxic perfluoroalkyl <br /> substances, commonly known as PFAS, in homes in Chatham, Orange, Durham and Wake counties in central North <br /> Carolina. They also tested in homes in New Hanover and Brunswick counties in the southeastern part of the state. <br /> https://www.fayobserver.com/news/20200205/not-all-types-of-in-home-water-filters-completely-get-rid-of-toxic-pfas[2/6/2020 11:49:44 AM] <br />
