Product review (1 stars): Horrible performance after a couple of weeks!
Both of these filters worked great....for about 2-3 weeks.  Then, the flow of the water got smaller and smaller and, within 4-6 weeks, it was taking a full minute just to fill a glass of water, and sometimes longer!  At first, we thought we just had a bad filter, so we swapped one out for the other new one.  The exact same thing happened; it worked fine for a couple of weeks and then got progressively worse, fast.  I will definitely not be buying these again!
