⭐ Key Features

•💧 REPLACES GE MWF AND MWFA: the twist-in cartridge GE sells as MWF is the same part sold as MWFA, HWF, Kenmore 46-9991. Fridges that take it include GSH25JSDDSS, GSS25GSHSS, PSS26SGPASS, GSH22JFXWW and the rest of the GE, Hotpoint and Kenmore fridges with the MWF cartridge inside the fresh-food compartment. Check the code on the cartridge you are removing against this list before you order. Full model list in the description below.

•💧 NSF 42 AND NSF 372 CERTIFIED BY IAPMO R&T: third-party lab tested and certified to NSF/ANSI 42 for chlorine, taste and odor reduction and to NSF/ANSI 372 for lead-free materials (under 0.25% lead). The housing is BPA-free, food-grade plastic; the block is 0.5 micron coconut-shell carbon. Both standards are on the IAPMO register under R-9991, which many four-packs for this fridge cannot say. The R-9991 certificate is on the box and on the register, which is where a claim becomes a fact.

•💧 CLEANER WATER WITHOUT THE GE PRICE: a denser coconut-shell carbon block removes up to 97% of chlorine, odor and bad taste, traps rust, sand and scale down to 0.5 micron and keeps calcium, magnesium and potassium in the water. That is what the R-9991 puts in every glass from a GE door. Flow to the dispenser and ice maker stays steady. Pay less than the brand for the same fit, or get more carbon and a certificate than the uncertified filters. Why pay more?

•💧 TWO YEARS COVERED: two years in one box: four filters, each rated for 300 gallons or six months, whichever comes first, matching the countdown on your GE filter light. Three stay sealed in their bags while the first does its six months. Change a filter earlier if the flow slows or the taste changes; that is the block full, not a fault. Every R-9991 box carries an install-date label for the next change.

•💧 TWO-MINUTE SWAP, NO TOOLS: the cartridge sits inside the fresh-food compartment. Turn the old one a quarter turn to release it and pull it out, push the new one in and turn it until it seats; the filter light resets itself on most models. Then run the dispenser about two gallons and discard that water; a cloudy first glass is harmless carbon dust. Cold water lines only. No tools, no plumber, no shut-off valve; the water stays on while you change it. Every R-9991 fits the same way.

•💧 REFRESH, US-BASED SINCE 2016: we have made replacement refrigerator filters since 2016, from a US-based company with US-based support. Every R-9991 is built to the exact dimensions and seal of the cartridge it replaces, so it seats and flows like the one you are taking out, is quality-checked before it ships, and is tested by an independent lab and certified by IAPMO R&T. Cleaner water without the brand price. Why pay more?
