Quick take
The OEM cartridge is GE XWFE. Compatible filters should explicitly support XWFE-equipped GE refrigerators.
Manufacturer-verified fit
GE’s parts page for GZS22IYNFS lists XWFE under popular refrigerator accessories.
Why the cartridge code matters
Use XWFE rather than guessing from refrigerator age or appearance because GE has used several filter families over time.
OEM vs compatible
OEM offers the lowest compatibility risk; reputable compatibles can reduce annual spend.
When to replace
GE’s XWFE guidance is about six months or earlier if flow is noticeably reduced.
