As soon as I saw the RO system, I read the reviews, and acted! I know only change water once a day instead of 4-5. I also only change the filter 2x a year instead of 6. It was a no brainer for me! I do keep minerals next to the machine and add a couple drops of trace minerals. RO takes everything out. It was easy to set up, but you need about 30 minutes to do it. Once it’s done, enjoy!
