There was a brand that worked by filling the tank with water and applying a vacuum to use the water as a filter. They weren’t amazing but they cost like $2k in 2001 money. My ex had one that her father had bought and I finally convinced her to get rid of it once it started shocking her.

Rainbow vacuums, my parents had one when I was growing up.
We still have one and it works really well. I suspect they were over filling the water reservoir
