Product review (5 stars): Don't Miss the Gasket!
TO THOSE WHO SAY THEIR FILTER LEAKS: Please note that after you unwrap and remove the foil cap for this filter there is a small, almost clear gasket where the filter meets the refrigerator water line, and it is loosely placed at the entry point at the top of the filter.  I just happened to drop that gasket on the floor as I was about to insert the filter or I wouldn't have known it was even there.  The GE GSWF filter gasket is an integral part of their filter and therefore not prone to separate.  With the gasket in place, the filter works fine.
