A multi-flexible filter, the MSWF model can be utilized in numerous GE, Amana, Hotpoint, and Kenmore refrigerators. The MSWF filter features an easy installation process operation and should be changed every six months to ensure optimal filtration performance. The factory original OEM GE brand has been rigorously tested by NSF International to ensure high-quality water for public health and safety. NSF International gave the MSWF model original OEM passing grades against Standard 42 and Standard 53. Such passing grades translates to a high grade of purified water the MSWF pumps out; reducing chlorine taste and odor, impurities, particulate, turbidity, cysts, lead, and other potentially harmful chemicals found in your water supply. Such quality water filtration will also contribute to healthier, clearer, and cleaner ice for your liking.
