The Clear Choice CLCH100 refrigerator water filter works to remove foreign contaminants from your indoor water supply. Designed as a replacement for the OEM part #4396508, this refrigerator water filter can be used in side-by-side refrigerators by Whirlpool Kitchen aid, Amana, Thermador, and other models. Clean, clear water can be available at your fingertips by utilizing this easy to install refrigerator filter. The CLCH100 creates better-tasting, clearer, healthier water and removes the taste of chlorine from your indoor water supply. The CLCH100 refrigerator filter removes impurities from your tap water by using a proven filtration method. The filtration process of the CLCH100 begins when water from your refrigerator enters the filter chamber. Inside the filter, there is a carbon-filled inner section. As water passes through the carbon, impurities are captured by the carbon and clean, clear healthy water is produced. This clean, healthy water is then available to drink free from contaminants. Over extended use, the carbon in the filter chamber can begin to degrade after more and more water passes through. To ensure that your filter is working to its peak capacity, routine filter changes should be made. Using a refrigerator water filter longer than recommended can lead to a decrease in water quality, future maintenance issues, and health concerns. This is why it is recommended that you make routine water filter changes every six months so that you never have to worry about not having crystal clear, refreshing water.
