I've gone through a shitload of those water filters while we were full time RV'ing. I didn't think they did anything toward deionization.
I'll have to give it a try.
I am getting quotes right now for adding a whole home water filtration system. (maybe a softener too) it will be installed in the small room in the back of my garage (like the room Clyde just got rid of) I'm thinking of having an additional line run to the garage door area that I can filter with one of
these
And I want to thank the recent round of stimulus checks for making these home additions possible
