Product review (5 stars): Perfect replacement filter for GE side by side refrigerator!!
This GE MWF fits perfectly in our side-by-side refrigerator, and it replaces the GWF filter that was in the refrigerator. No adapter was needed. The GWF popped out easily, and the MWF just as easily popped. Per the refrigerator's user manual, we filled a few glasses full of water to get the air out of the line with my brother getting soaked in the process because of his teenage son's shenanigans, lol. That was kind of fun to watch, actually :-)

P.S. We received the MWF filter as promised (not the MWFINT filter that others have described receiving in error). I clicked to search for the MWF from Amazon as the only purveyor so that I knew shipment was coming from their warehouse (and an easy exchange would be possible).
