Quick take
GE XWFE is the OEM replacement. For cheaper options, use only cartridges specifically documented for XWFE-equipped GE refrigerators.
Correct cartridge
GE’s parts page for GFE26JYMFS lists the XWFE refrigerator water filter.
OEM advantages
GE XWFE provides the cleanest manufacturer-supported fit and performance reference.
Compatible-filter risk
A filter advertised for XWF is not automatically the same as a true XWFE-compatible cartridge when electronic recognition is involved.
Recurring cost
Because this is a repeat purchase, annual cost is a better comparison metric than one cartridge price.
