Review on Ultimate Water Purification: CuZn UC 200 Under Counter Filter by Josh Thompson

The UC-200 filter does not retain calcium in our faucet. This is disappointing. UPDATE: After reading my comment above, the company quickly contacted me by phone. Working with a helpdesk employee, Chris, I was able to determine that the main cause of the limescale build up was the water heater that powers the entire house. This was a known problem that the UC-200 couldn't solve until I replaced the ten year old hot water unit. However, they sent me an updated replacement filter that seems to fix the problem pretty well. I'm REALLY impressed with the quick, no-hassle, and satisfying response I received. Who has ever heard of any company doing something like this? I was and still am very impressed with the fact that the UC-200 performs as well as advertised, eliminating odors and dramatically improving the taste of our drinking water. We no longer need Britta filters and jugs.
