The factory original Frigidaire is the only brand we have available for the filter model WF2CB. The good news is that this may certainly be the only brand you'll need. Great effort and meticulous design was put into Frigidaire's WF2CB filter. It showed when it was tested by NSF International to ensure public safety and health. Frigidaire's WF2CB met both International Standards 42 and 53. Such a high grading ensures the customer's filter will help reduce potentially harmful contaminants such as turbidity, cysts, rust, and chlorine. It is important to remember to change your filter at least once every six months to ensure a high performance in water filtration and dispense rate. Filters will not necessarily function efficiently if they are not properly maintained, leaving open the possibility of letting harmful contaminants into your water.
