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.


Get an under-sink RO system. 6 stage is the sweet spot imo.
Water went from 750 TDS to 40, and that’s with minerals readded with a mineral adding filter. Tastes as good or better than bottled water to me.
If you have hard water, it’s true that water softeners can help with other issues in the house (scaling of faucets, dishwasher cleaning I effectively), and possibly if your family has skin issues from showering in it. I thought about it but for simplicity, we’re foregoing for now.
Yeah I had an RO for years at my last house. However, I bought new filters one time and my entire system smelled and tasted like mold after installing them. I always sanitized the entire system per their directions. 13 years no problem then, a problem. They also straight up refused to talk to me about it so maybe avoid US Water Systems…
I’ll second that opinion. RO filtered water basically is the same as overpriced bottled water, but you can have all you want at home anytime in your own glass
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.
Wow. I go from 350 to 8 ppm on an 5-stage APEC and thought that was amazing.
