Sometimes your ice and water can taste a little "off." Refrigerator water filters are made to not only reduce the contaminants found in your water, but to ensure that you water and ice taste the way you want it to. That’s where the 4396508 water filter comes into play. We offer 3 models of the 4396508 filter: the OEM Whirlpool replacement, the aftermarket EcoAqua replacement, and the aftermarket Supco replacement. All of these models help clean your water of contaminants and bad odors by forcing the water through activated carbon which traps the impurities. The 4396508 filter has a filtering capacity of 400 gallons while delivering your water at a rate of half a gallon per minute. Installing a new filter is extremely easy and we recommend doing so at least once every 6 months to ensure your water remains clean and healthy for you and your family.
