We are in the same boat for sure with our city water. You may want to look into one of these. I have really bad sediment in my water. Literally every time i made water sed filter got orange. I actually ran a sediment prefilter stage becaus I used them up so fast. literally One time use only, and the calorie I can smell from across the room sometimes. A friend recommended one of these And i am on month 6 now and my sed filter is still pure white. and I haven't had a whiff of chlorine since either. Between this and a softener, your RO will thank you it will pay for itself in a couple years easily. https://www.lowes.com/pd/Whirlpool-Whole-House-Complete-Filtration-System/1082883 edit: er wait looks like you may already have one. is this what you have and you can still smell the chlorine?
