How often should I replace the water filter, and what is the replacement part number?

You should change the water filter every six months to ensure the highest possible water quality, or after 200 gallons (757 liters) of water have flowed through the system. The replacement filter is the PureSource 3™ Water Filter, Part #WF3CB, available at www.frigidaire.com/store or by calling toll-free 877-808-4195. (Page 18)
