FI-RF-WSM refrigerator replacement water filters are designed to meet the the performance of the original filter.
This WaterSentinel™ refrigerator water filter contains a compressed carbon block which provides tremendous capacity to reduce impurities such as sediment, chlorine, taste, odor and organic contaminants which may be present in your drinking water. The carbon block has millions of active sites on its surface and within the structure which can adsorb impurities like a sponge, and can hold other types of impurities on its surface like a magnet.
Our FI-RF-WSM filter can catalytically break down 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 from a refrigerator filter.
