We bought this water filter because our water is very hard and it pollutes toilets, showers, sinks etc. This device was recommended to us. I liked the fact that it was small and didn't take up as much space as a freestanding unit. We've had this for over 6 months now. I couldn't tell any difference in the quality of our water. The toilet is still being polluted with hard water every week. I still have to clean it with a pumice stone every week. We spent several hundred dollars on a plumber to install the system. I actually had to ask my husband if he turned it on and then check myself to make sure it was on. I am very disappointed and would not recommend it to anyone.
