Anyone have a robust filtering system? From reading the thread some people recommended a reverse osmosis system. But then that is demineralized which the WHO says leaches minerals from the body.

So one ought to remineralize, and do so in correct proportions, for both calcium and magnesium but also trace minerals. And certain things sometimes recommended to reminerslize (pink himilayan salt) can contain lead.

Is there some simple all on one system in north america that solves this?
