We had decided to buy this because of our city water in our county. When we got this, they decided to change the chemicals for 3 weeks for a water cleansing and it smelled like bleach so bad. We installed this the next day and it too out the smell right away. We've had this for just over 2 months now and there is a different not only with the smell, but the taste and clarity as well. It is so much better that I can cook with it now.
