The Maytag UKF7003AXX PuriClean water filter produces cleaner, better tasting drinking and cooking water by reducing chlorine taste and odor as well as sediment and cysts, lead and turbidity. The UKF7003AXX has a filter life of up to 6 months or 250 gallons, but should be replaced sooner if you notice tastes and odors returning to the water, the water pressure is greatly decreasing, or the filter monitor light on the refrigerator has turned red.
