My family have all increased our water intake because our under the counter Aqualiv filter makes our tap water taste so fresh and clean. We had a reverse osmosis water filter before we made the switch. The reverse osmosis used up too much water and it had to have minerals replenished before drinking, plus it didn't last long and broke after just a year. We have had our Aqualiv for 5 years. It even made it through our move into our new home. Aqualiv water removes fluoride, doesn't leach out all the healthy minerals and it structures the water. I feel hydrated for a longer period of time.
