I know some people who have well water and they use something like that.
Unfortunately I don't know that you're going to get effective filters that have no plastic due to it being too cost effective for a disposable component.
You can't use paper or cardboard because it's water permeable, and metal would drive up the price of the filter drastically.
Epic is the only solution that didn't need a plumber that gets the toxic stuff that's in my water out, some kind of probably common pesticide or herbicide at like 50x the EPA limit. You can taste and feel the difference. They seem really good. And you never know what's in that water before hand.
My stainless-steel countertop water distiller. Although the water passes through a short bit of plastic tubing, it is at best lukewarm when it does so. I don't worry as much about plastic contamination as I would with anything else.
If you've got someone excessively-fragile, with some medical-condition that makes 'em that way, use Zero Water filters: they are costly, damn-thorough, and amazing, when you can't drink anything else.
Yeah, in order to purify water with boiling it's necessary to capture and condensed the steam. This distilled water is often considered too clean because it doesn't have certain minerals our bodies usually get from water.
