We have AO Smith RO system for drinking water. We never noticed an odor or taste of unfiltered water. Now that we have this system, the water is crystal clear, a “pure” flavor.We had a friend who was not a believer when I shared this with his family. We did a blind test of unfiltered water and filtered water - they picked filtered water five of five times. With better taste, we are consuming more water.I highly recommend the system and the filter. It seems expensive but worth every penny. Filters are about 15% cheaper on Amazon.
