Bests & Worsts Reviews from Amazon

I bought this ZeroWater 8-Cup Water Filtration Pitcher to replace my Brita and as an option other than purchasing a PUR. I based my decision on the TDS reading of 000. I had tested my Brita and the tap water and both readings were in the 300 - 400's. As soon as I received the ZeroWater Pitcher, I tested it and it was close to 000. And the water tasted amazing! I loved it! I used it every day since July 15. But starting yesterday my water started tasting sour. I thought it was the cup I had reused after drinking apple juice because I needed water to drink to take a probiotic pill. Then today at work, the water in my CamelBack water bottle tasted funny. I thought it was dish soap from washing the CamelBack. I decided to test my ZeroWater again and the reading was 796! What!? So I did another test and it was 550! The tap water itself was 400! It went higher and it went sour! I was also horrified to realize that I had been giving my cats this water and mixing this water with their food. I quickly dumped out their water bowls and gave them bottled water (Refreshe water from Vons). I also discovered dried up cat vomit on the carpet. They must have puked from this morning. I do not blame them as I wanted to vomit too after sipping the water to taste to figure out what had happened! I decided to not order any more filters after reading more reviews on Amazon and on the ZeroWater site itself. Changing the filter every month because the filter starts producing water that is sour and rancid is not worth the expense to have delicious water for only 2-4 weeks. I would like a better solution to having clean inexpensive water and to reducing the plastic water bottle waste. Please note the water tester that comes with the pitcher is generic. It says "If your filter is installed correctly and working properly, the indicator WILL NOT LIGHT UP." But I ask what if the indicator is broken? Will you think it is working? This is not the advertised tester. You need to order a separate TDS meter from them for $9.99. That's baloney. I bought a separate TDS meter "TDS-EZ" by HM Digital. It is reliable and accurate. Thank you for reading my review.
