I've had my Zero Water dispenser now for over a year.  It reminds me of when I was growing up in the High Sierras when the water was remarkably fresh and you drank a lot of it.  My health has improved over the past year most likely from now drinking a lot more water because it tastes delicious.  Interesting too that my "Pomeranian" prefers Zero Water over tap water; we show people all the time how she will only drink from the Zero Water bowl when given a choice.
