This is not true. The NSF/ANSI standard 53 specifies that filters must remove PFOS/PFAS[1], and both reverse-osmosis (RO) units /and/ granulated activated carbon filters are certified under that standard. Granulated activated carbon filters are the same kind found in Brita filters. For example, Samsung RWP70010TWW is a refrigerator filter approved[2] for filtering PCBs, PFOS, and PFAS, as well as a whole host of other things. You don't need to spend ten thousand dollars installing a reverse osmosis system to get clean water. 1: https://www.nsf.org/knowledge-library/perfluorooctanoic-acid-and-perfluorooctanesulfonic-acid-in-drinking-water https://www.nsf.org/knowledge-library/perfluorooctanoic-acid... 2: https://info.nsf.org/Certified/DWTU/Listings.asp?ProductFunction=053%7CPFOA+Reduction&ProductFunction=053%7CPFOS+Reduction&ProductFunction=P473%7CPFOA+Reduction&ProductFunction=P473%7CPFOS+Reduction&ProductType=&submit2=Search https://info.nsf.org/Certified/DWTU/Listings.asp?ProductFunc...
