Harvested from published manufacturer and retailer fit lists (sources at the bottom of this page). If your exact model is not listed, do not assume fit — check the number on your current part.
GE (47)
PARTIAL LIST. GE publishes only 'select GE side-by-side and bottom-freezer refrigerators'. The 47 model numbers recorded are the complete list printed in a long-running GE MSWF retail listing (sourced from GE's original product copy); treat as partial against the full installed base. MSWF and GSWF are NOT interchangeable (per GE support). GE marks MSWF 'This model is no longer being manufactured' on its product page, though genuine stock remains on sale.
Certification
Maker claims NSF/ANSI 42, NSF/ANSI 53 — no independent certifier listing was found when checked on 2026-11-11. Treat the claim as unverified.
GE's MSWF performance data sheet states the system was tested and certified in model GE MSWF by NSF International against NSF/ANSI 42 and 53. Under the certifier-listing rule this is NOT 'certified': an NSF DWTU trade-name search for MSWF opened directly on 2026-11-11 returns only aftermarket manufacturers (Ecolife/Qingdao Ecopure, Pacific Citadel) - no GE listing - and GE Appliances' own NSF/ANSI 42 company listing contains no refrigerator cartridges. Recorded as manufacturer_claimed.
