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.
This is the correct database to use. In the US, we haven’t invested any official effort into updating our drinking water standards in many decades. So take whatever your municipality or water supplier says about your water quality, with a grain of salt. Maybe a very large bag of salt.
No, its not the correct database to use because EWG is bullshit who lists anything above a functional zero as dangerously contaminated, with links to sell you water filters for every bullshit claim they make.
