I have tried using straight tap water and also filtering through a carbon filter first. My tap water doesn't taste bad. I just bought this because I wanted to drink distilled water and make cs but I don't like the way store bought distilled water tastes. It tasted like plastic. I also used the filter after the water is distilled to filter out the bad plastic taste and it still tastes funny. I can't drink water that tastes so plasticky. I bought two of these distillers! They were on an after Christmas sale from Comfort House. Any suggestions? Doris
