Product review (2 stars): I also found after a few weeks my water tasted like it was from a not clean glass
These don't seem to be as effective as the GE brand ones are. They don't really slow down the flow of water over time and lead me to believe they are not filled with the proper filter medium that will restrict water flow over time as they near their expiration. I also found after a few weeks my water tasted like it was from a not clean glass. Maybe I just got a bad batch? So far all 3 have performed about the same for me.
