I have had a 5 stage reverse osmosis system for 20 years and love having good, clean water at home. I knew that a reverse osmosis membrane removes all the "elements" from the water, good or bad. This 6th stage allows me to put some of the good "elements" back into my water. It seems well made and was very easy to add to my existing system. Should have been there from the start.
