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.
Why is removing the chlorine important to your wife? Why does she think a filter won’t introduce more microplastics than it removes? Is the entire filter system plastic free? (The answer to that is "no. ")
