What it costs over five years

Replaced on the maker’s interval, the schedule the fridge’s own filter light keeps, at list price. Every filter is counted: the one that came with the fridge is long gone. It is rated for 200 gallons, so a household drawing more than about 1.1 gallons a day through the fridge runs it out sooner.

Which refrigerators it fits

Made for Frigidaire refrigerators, but no maker’s page TapBuff could read lists the models it fits, so none are listed here. Your refrigerator’s manual names the filter it takes.

Worth knowing

Frigidaire showed it on sale for $45.00 on Oct. 9, 2026; the list price is used here. Frigidaire says to replace it every six months, sooner for a bigger household.
