Product review (1 stars): Yuck
The instructions say to run at least 4 gallons of water through before using.  I have exchanged all my ice two times, and have run at least 20 - 25 gallons of water through this filter.  The water still tastes horrible.  It leaves a bad taste in your mouth and is unacceptable.  I have always ordered Pur filters before, and from now on they are the only brand I will purchase.  Never had this problem with a Pur filter.
