About This Item
"GLACIER FRESH Replacement for Frigidaire ULTRAWF Refrigerator Water Filter's material and structure meet the NSF42 standard. This Pure Source Ultra replacement filter uses 100% coconut shell carbon blocks selected from Sri Lanka, which maximizes the filtration effect. The filter can removes impurities while retaining beneficial minerals. For the best performance, we recommend replacing your PureSource Ultra water filter every 6 months or after 300 gallons of water has passed through it, whichever happens first, based on your water quality. Follow the instructions and install in minutes with no extra tools required."
