Product review (1 stars): Surprise: GSWF is not a universal standard
As other reviews here note, this filter does not fit all GSWF refrigerators. Customer service at Swift was very apologetic, and even sent me a replacement, but it has the same non-fit (it appears the center hole is just slightly too small and therefore the outer threads never meet). They put me touch with their tech staff, who told me that the major appliance manufacturers periodically change the specs of their water filter "receivers" without changing the number of the standard (in this case, GSWF). So if you think GSWF is a universal standard, think again. It appears I will now have to buy an original GE branded filter for about four times as much.
