Let me start this review by saying, my family goes through so much bottled water, it's ridiculous! So I figured why not give a purifier a try. I have to say I was pretty skeptical that this purifier was going to make a difference. We all tried it and I have to say, We are impressed!! We took a bottled water( won't name which one) and emptied it into a glass. We took another glass and filled it with Tao water we out through the purifier. None of us could tell the difference. The water from the purifier was just as good, if not better, then the bottled water. I would definitely recommend trying this purifier out!! It was the best decision I made. We are saving so much money on cases of water, and also helping save the planet with less plastic bottles.
