PARTIAL LIST. GE publishes only 'select GE side-by-side and bottom-freezer refrigerators' and no model list. Fit models harvested from Waterdrop's WD-F13 compatibility table (a manufacturer-of-replacement published list, not GE's); the full MWF installed base is far larger (hundreds of models), so this is visibly partial. Twist-and-lock cartridge in the back upper right of the fresh-food compartment.
Certification
Certified: Yes — NSF/ANSI 42, NSF/ANSI 53, NSF/ANSI 401 by IAPMO R&T, verified against the certifier's listings on 2026-11-11. (Certificates: NSF/ANSI 42 (W-9755) · NSF/ANSI 53 (W-9756) · NSF/ANSI 372 (W-9757) · NSF/ANSI 401 (W-9758))
GE performance data sheets state the MWF system was tested and certified by NSF International against NSF/ANSI 42 and 53 (reports incl. J-00077703/J-00121587); GE's current sheet (49-6000042) instead states the system is certified by IAPMO R&T against NSF/ANSI 42, 53, 401 and P473. Under the certifier-listing rule this is NOT 'certified': NSF's own DWTU listings opened directly on 2026-11-11 show no GE Appliances refrigerator-cartridge listing (the GE Appliances, a Haier Company NSF/ANSI 42 listing covers only RO/point-of-entry products, and a trade-name search for MWF returns only aftermarket makers such as Qingdao Ecopure), and the IAPMO directory listing could not be opened (JavaScript app, text fetch returns only the shell). Recorded as manufacturer_claimed. Direct-listing verification 2026-11-11: GE's certifier for this cartridge is IAPMO R&T, not NSF — which is why the NSF directory searches above found nothing. IAPMO R&T certificates W-9755 (NSF/ANSI 42), W-9756 (53 — includes PFOA/PFOS claims for MWF), W-9757 (372) and W-9758 (401) were opened directly at myplc.iapmo.org, all Status: Active, naming this cartridge. Status upgraded to certified.
