There are three brands you can choose for the MSWF model water filter; GE, Swift Green, and Supco. The GE brand is the factory original OEM product. Swift Green and Supco are both aftermarket carriers of the MSWF model water filter. All brands have advantages and disadvantages that will factor into your purchase decision process. The strength of the factory original GE MSWF lies in its NSF/ANSI International certifications. The GE brand was certified against Standard 42 and Standard 53, very high grades in regards to water filtration performance. The other two aftermarkets were not certified by NSF/ANSI in such purity performance testing, showcasing the quality of the GE brand. The GE brand, however, is also the most expensive. The Swift Green brand is most wallet-friendly in regards to price. Supco brand leads the way in the MSWF model class when it comes to gallon capacity at 750 gallons.
