The Auto Fill Pitcher uses the AFPWF integrated stow-away filter. This filter is designed to be used only for the Auto Fill Pitcher. It will not filter water to an icemaker. This filter has a 6 month or 170 gallon filter life, and creates great tasting water by reducing chlorine taste and odor. Installation for this filter is a breeze and no tools are necessary. Knowing when to replace this filter is made easy by the LED filter status indicator lights. Green means the filter is good and your water should be tasting great, yellow means it is time to replace the filter. Once the light is yellow you have a two week window to order and install your new filter. If the light turns red it means your filter has expired and is no longer working. This filter is hassle free and takes the worry out of keeping your water clean and tasting great.
