Product review (5 stars): Great alternative to the OEM Filter (GE MWF/GWF)
My refrigerator filter uses the GE MWF (previously the GWF) filter, and this works flawlessly to replace it.  At more than half off, this is an excellent alternative to the manufacturer's filter.  It installs quite simply, does not leak, and only takes about 2 minutes of running to flush out all of the water.  It seems to have slightly more pressure than the previous filter, but this could also be because the other filter was so old.  The water tastes great now!
