Why OEM, not compatible?

For most homeowners, our Compatible MWF (NSF 42/53 certified, $10.99) is the smart choice. Buy the OEM if:

• You are still under GE warranty and want it intact
• You prefer the official packaging and serial number for records

Installation (2 minutes, no tools)

1. Locate the filter compartment (top-right inside the fridge or bottom grille)
2. Push in and rotate or pull the old filter to release
3. Insert the new MWF and push until it clicks
4. Run 2-3 gallons through the dispenser to flush carbon fines
