Watts Kenmore Refrigerator Replacement Filter Cartridge

This W-4 refrigerator water filter contains a compressed carbon block which provides tremendous capacity to remove and/or reduce impurities and sediment that may be present in 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 an automobile. These processes ensure that the cleanest and best tasting water possilbe is provided. This filter should not be used with water that is microbiologically unsafe or of unknown quality, without adequate disinfection before and/or after the filter.
