The PuriClean® II Water Filter fits Amana®, Maytag® and Jenn-Air® side by side (cabinet depth, built-in and wide by side) and french door refrigerators with a long, narrow filter that sits in a "trough" that swings down from the ceiling of the refrigerator. 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.
