Water that comes from the tap isn't always as clean, or as healthy as you want it to be. The 4396701 filter helps fix that. This filter fits into many Whirlpool, KitchenAid, and Jenn-Air refrigerator models. This filter has a filtering capacity of 200 gallons and will produce fresh water at a rate of one gallon per minute. When properly installed into your refrigerator, the 4396701 filter helps reduce chlorine taste and odor and helps remove contaminants from your water. Some of these contaminants include lead, mercury, and benzenes, all of which can make you and your family sick. We offer three different brands of the filter: The OEM Whirlpool replacement, the aftermarket AquaFresh filter, and the EcoAqua replacement filter. We recommend changing this filter once every 6 months to ensure that your water remains clean and contaminant-free.
