Product review (1 stars): Did not fit!!!
I ordered the exact model number that is on my old filter, and the new one was labeled with this same model number.  HOWEVER, it does not fit!  These filters have plastic tabs that fit into the refrigerator like a key to ensure that you do not try to put in the wrong filter.  These tabs are in a totally different configuration from the old filter.  Take my advice, and go to a physical store when buying your replacement filter so you can compare them! At $50 a pop, it is worth the drive to your local Big Box store.
