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.


You have to be specific to answer properly. Where do you live (how is your water) and what treatment/filtration are you considering.
Lots of folks on well water have hard water, bad tasting, etc… Other may have lead, or other pollutants.
The truth of the matter is you should get ypur water tested at an independant lab. Based on the results, you can tailor a system to your needs, if any.
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. ")
You are only partially correct. The systems have plastic in them, but that’s nowhere in any way a guarantee they’re adding more plastic than they’re removing. At all.
Ok, but where the evidence it’s actually removing more than it adds? You won’t get a study like that from the company selling them.
Also where’s the study on OPs city water showing the level of Microplastics?
I’m not claiming anything, I’m asking the questions of OP they should be asking with their wife.
Where is the study reinforcing your claims?
You can say, “I’m not making a claim of my own” all you want, but you are!
Just as there is no evidence that microplastics actually cause any disease. Remember when we were kids and loved to chew on lead blinds?
Without a test you wouldn’t know. Cities have lead, pfas, god knows what. Older areas of cities may still be using lead pipes.
