I have been buying these for a while and was hooked on the taste. Then we moved to an area where the water is from a well and it's YELLOW! I was very hesitant to use tap water in this case, but when I saw the difference of the water coming out of the filter it was hard to believe it was the same water. It still taste great and now we really need the filter. The only down fall, which I can't take any stars off is the price.
