Product review (1 stars): Bad.
Replaced my old blue pur filter with this one. Didn't notice any difference in taste or other problems. However, the filter only lasted 2 weeks before it got clogged. The water won't dispense with this filter installed. For $50 this is unacceptable. Never had this issue in the 6 years of using the older blue ones and I did replace them every 6 months.
