My wife is pushing for one of these very expensive home water treatment/filtration systems, but it all feels like a scam to me. No one I know has one, so turning to random strangers on the internet for opinions.
Edit: We’re on city water in a decent area. No well water. It’s more about removing the chlorine and microplastics than anything.


RO is definitely the way to go, though interesting you couldn’t get it below what the meter could detect. Both of my RO setups get to 0 detectable from ~500ppm, and one’s only a three stage.
Yeah I think my RO membrane probably isn’t a top quality one, as it has a rated TDS rejection rate of 97%, so absent of the mineral-adder, that probably tracks. I think the adder does throw about 20-30ppm back in and evens out the pH.
Yeah, a mineral re-adder will definitely bump the numbers back up. A lot of what those PPM measurers detect are those similar ions and such that trigger peoples’ tastebuds.
