Product review (1 stars): Doesn't work
Unfortunately, I decided to ignore the previous negative reviews and ordered this replacement filter.  It is simply terrible.  My old filter looked exactly like this one and was still working perfectly--it just was time to replace it.  After replacing the old filter with this one, each time I draw water, the system makes a terribly loud groan--as if the pump is struggling to move water through it.  That make sense considering I now get only a trickle of water from the system.
