Product review (5 stars): Increased water pressure
I purchased the "GE MWF Refrigerator Water Filter", which is the actual model recommended for my refrigerator/freezer/ice maker.  It was very simple to install without any tools.  Although my water was still dispensing clear on the old filter, my water pressure noticeably increased after changing the filter (so yes, it was overdue).  Our public water system is consistently rated exemplary on the annual water tests, but it is comforting to have the extra filtering just in case.  There were cheaper brands available, but after reading the materials and other reviews I felt that they original was worth a little more.
