A slim GE cartridge used in a limited set of side-by-side models, often confused with MWF.
About this cartridge
MSWF uses the same twist-lock principle as MWF but a shorter body and a different collar. It appears in a narrow band of GE side-by-side models and is frequently mis-sold as an MWF equivalent.
Certified to 42 and 53 at 300 gallons. Availability is lower than MWF, and pricing is correspondingly less competitive — check whether the housing will actually take an MWF before paying a premium.

These part numbers refer to the same physical cartridge. If the number on your old filter is in this list, this is the right replacement.
Not an MWF substitute. The collar diameters differ.
Which refrigerators it fits
GE has not published a model-level list for this cartridge that we can verify, so we do not publish one either. The number on the cartridge you are removing is the reliable check.

Open GEReplacing it
- Turn the old cartridge a quarter turn counter-clockwise and pull it straight out. Keep a towel under it — a few ounces of water will come out.
- Remove the protective cap from the new cartridge and check that the O-rings are seated flat in their grooves.
- Push it in and turn clockwise until it stops. Run two to three gallons through the dispenser to flush carbon fines, then reset the indicator.
