ZeroWater makes a carafe that reduces total dissolved solids to 0 ppm, including PFAs and microplastics, or so they claim. I have tested it with two different monitors, and it is indeed 0 ppm, which is good enough to be considered distilled water by the FDA. The filter does not sustain that level of efficiency for very long if there are lots of solids to clog it (i.e. ymmv depending on your water source. Some people prefilter, but who has space and time for that?). I’m not sure it’s capable of filtering to the nanometer scale, but then again I’m not sure anything can, which is why this is so frightening for life forms.

Other devices you can install with some rudimentary plumbing knowledge are BWT or Pentaire reverse osmosis filters. They do a good enough job at filtering, though they waste a lot of water in the process. I use these at work and I the Pentaire allows you to control ppm, which is suitable for coffee aficionados. You can always remineralize your water once you get the junk out.
