The Maytag® PuriClean® Water Filter fits Maytag® & Jenn-Air® side by side refrigerators with a round, screw-in filter located inside the refrigerator compartment above the top shelf. It reduces Chlorine taste and odor, particulates, and more. This model is NSF certified which ensures this filter meets the strict NSF quality standard. Make sure you replace your filter every 6 months or when the "change filter" light comes on - whichever comes first.
