> a good RO system can filter out most microplastics from the tap water, but it also releases some (of its own) into the filtered water

Home distillation is cheaper than RO (esp. if you have solar) and doesn't release microplastics. Just remineralize with a high-quality salt

You bet - I’m sure it’s the only fool proof way to get rid of all microplastics. Cumbersome though. But realistically, I no longer think they can be avoided. Probably already lodged all the way up in my brain waiting to cause some nuisance as I get older :-/

Our best hope is nanotechnology and bots or maybe even bioengineered cells or microorganisms that can get in there and eat them or at least reroute them out of the human body through natural pathways.

Home distillation probably only works if you have all copper plumbing instead of the PVC or PEX plumbing that a lot of homes have. But copper plumbing is probanly going to leach various metals into the water.
No? Your plumbing shouldn’t matter if you’re distilling the water.

Some volatiles are going to come through (which can be mostly mitigated with an activated charcoal filter at some point in the process), but you’re vaporizing the water and condensing it back into a liquid, leaving behind stuff like metal and microplastics.

Sure, but unless you're distilling the water at point of use, you'll have plumbing to distribute it. The typical setup is to have a distillation plant, some storage for the water and then plumbing to distribute it. Anything else quickly becomes infeasible.
Do you have any concrete products you can recommend for home tap water distillation? Searching for such a solution mostly yields DIY results for me.
Which salt could you buy that’s free of Microplastics ?
