The U.S. Environmental Protection Agency has decided to ban Berkey water filters, officially labeling them as pesticides. Berkey has sued the EPA in response to their sudden and unorthodox reinterpretation of their own regulations. Berkey water filters are regarded by many as some of the best filters money can buy, and several of Berkey’s products have been featured on Good Morning America, Martha Stewart, Food Network, Thrillist, Goop and Forbes. Berkey products, which have been on the market for a quarter century, became popular due to their gravity purifier and filtering elements that can remove hundreds of waterborne pathogens and contaminants.
