Dear Mr. Tee,
I personally use the eSpring water purification system and I am very happy about it. It is the first, and so far the only system that exceeds all three NSF standards 42, 53 and 55 re. water purification, the water tastes much better than the chlorinated municipal supply and I have peace in my heart that my daughters are drinking the best system for my home money can byu. You can look it up in
in no less than 18 languages!
