I think you're wrong. I did extensive research on this prior to purchasing a home recently and the general consensus I found is that you need a pretty advanced water filtration system consisting of carbon + reverse osmosis filtration that requires yearly servicing. Some water companies do this, but most probably don't. You can also have a system installed in your house. Your standard Brita filter doesn't even come close to filtering these chemicals.

It’s the distillation that gets rid of everything else, not the filtering

  AFAIK, distillation will not remove volatile organics that have a lower boiling point than water(well, theoretically you could do some fractional distillation technique, but its easier to just run a carbon filter).

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...

  An under-sink RO system is only $200 in hardware, and I'd estimate (from my own) costs about $40/yr in service.
