The MWF-2 replacement filter is suitable for GE refrigerators with a round white plastic filter, typically mounted inside the refrigerator, at the rear of the compartment above the top shelf.
The MWF-2 filter replaces these older filter part numbers: GE SmartWater GWF, GWFA, GWF01, GWF06, MWFA, MWF, Stefani fridge filter SGF-G1. Also interchangeable with the Eco Aqua EFF-6013A, Water Sentinel WSG-1, Aqua Blue MWF-WF and the Puretec Model Number RF10.
The MWF-2 for GE adheres to all the rigorous testing and manufacturing guidelines set out by NSF International.
Refrigerator manufacturers recommend that fridge filters be replaced every 6 months or when the "change filter" light comes on.
