There are two brands you can choose for the AP3997949 model water filter; GE and the aftermarket IcePure RFC1500A. The GE brand is the factory original OEM product. All brands have advantages and disadvantages that will factor into your purchase decision process. The strength of the factory original GE AP3997949 lies in its NSF 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 in such purity performance testing, showcasing the quality of the GE brand. The GE brand, however, is also the most expensive. The IcePure brand is most wallet-friendly in regards to price.
