Product review (2 stars): Not effective
When I first installed the filter, it took way more than the typical 5 gallons to have break the filter in. The water was full of micro-bubbles and the taste was not good until a good amount of water had been wasted. After the initial break-in period, the water from the dispenser was fine. 3 months after purchase, however, the taste suddenly turned a little metallic and it seems like the filter has lost its effectiveness.
