How To Install The MSWF Filter:
- Remove old filter cartridge by grasping and slowly rotating to the left (counterclockwise)
- Position new cartridge inside the cartridge holder and slowly rotate the cartridge to the right (clockwise) until it stops. The cartridge will rotate about 1/2 turn. Do not overtighten
- Flush 4.5 gallons through the filter before use. This will clear the system and prevent sputtering

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.
NSF/ANSI Standard 42
Filters tested against NSF/ANSI Standard 42 (aesthetic effects) are certified to reduce specific aesthetic or non-health-related contaminants (chlorine, taste and odor, and particulates) that may be present in public or private drinking water. See filter performance data sheet or manufacturer's packaging for details.
NSF/ANSI Standard 53
Filters tested against NSF/ANSI Standard 53 (health effects) are certified to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether), etc., that may be present in public or private drinking water. See filter performance data sheet or manufacturer's packaging for details.
Filters Without NSF Ratings
Some filters that are not NSF rated are still constructed from NSF rated components.
Save Your Furnace Tip #5:
Make sure your filter fits snug in its slot or cabinet. Gaps that allow air to bypass the filter can significantly reduce its effectiveness.
