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