Quick take
The manufacturer-supported filter is GE XWFE. Compatible cartridges can be cheaper, but verify XWFE electronic and physical compatibility before ordering.
Correct replacement
GE’s GNE27JYMFS parts page lists XWFE among the model-specific refrigerator accessories.
XWFE ownership
GE markets XWFE with a six-month filter-life guideline and 170-gallon rated capacity.
Compatible alternatives
The strongest aftermarket replacements explicitly document XWFE compatibility rather than only claiming they fit older XWF housings.
Where to compare
Replacement-filter specialists can be useful because they stock multiple compatible brands for the same cartridge family.
