WaterSentinel WSW-4 Refrigerator Replacement Filter: Fits Whirlpool 8171413, 8171414, EDR8D1, Kenmore 46-9002

This premium WaterSentinel replacement refrigerator water filter contains a 0.5 micron coconut shell compressed carbon block which provides tremendous capacity to reduce impurities that may be present in your drinking water. The carbon block has millions of active sites on its surface and within the structure which can absorb impurities like a sponge, and can adsorb and hold other types of impurities on its surface like a magnet. Additionally, this filter can catalytically breakdown other impurities very similar to the way a catalytic converter works in your automobile. These processes ensure that you are getting the cleanest and best tasting water possible.
