Bests & Worsts Reviews from Amazon

...when it is the TDS reading for my well-water. I thought ZeroWater was the answer to my prayers--and it was, for FOUR days. For 4 days I had perfect water, but on the 5th day the water tasted like lemons, which is "the sign" that it's time to change the filter. According to ZeroWater's very friendly & sympathetic customer service rep, with the high TDS content in my water, each ZeroWater filter will give me about 8 gallons of wonderfully clean-tasting water. It's far cheaper for me to buy Walmart purified water (which has 006 TDS, btw) and pour it into my filterless $45 23-cup ZeroWater container than it is to buy filters. Can't fault ZeroWater--much. And yeah, I cried.
