Product review (1 stars): Not a GW GWF Filter Replacement
As another commenter has pointed out (wish I'd seen their comment before), this filter does not universally fit as a GE MWF replacement. The head is too thick for my GE Profile (which takes a GWF, which is allegedly MWF compatible). I tried various directions and even compared tab alignment with the filter it was meant to replace, to no avail.
