Consumers use the Frigidaire WF2CB water filter in their Frigidaire, Electrolux and Kenmore Pure Advantage and PureSource2 Ice and Water Filtration Systems. As it meets NSF International Standards 42 and 53, it reduces dangerous and distasteful contaminants that might be present in the water. Chlorine, cysts, turbidity, chemicals and other particulates stay trapped in the filter. Replacing the filter every six months ensures a water flow rate of half a gallon per minute. The filter may need to be replaced sooner if it reaches its filtration capacity of 400 gallons or if the flow rate or water quality decreases.
