Interesting, but boiling all of our water would use a lot of energy. And most filters don't get small enough to remove microplastics and PFAs. Reverse osmosis systems do though, and you can get several that will install under your sink. I bought a APEC system and am super happy with it. Even though plumbing is about my least favorite home DIY, the kit came with most stuff I needed and I got it done. I even plumbed in my coffee maker (no more filling up every morning! best thing ever), refrigerator and hot water dispenser. These do exist for large scale too, removes more from the water, and very likely less energy intensive.
