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

Mist says it replaces XWF, WR17X30702 (Mist’s page, checked Oct. 9, 2026). So it should fit the refrigerators those originals fit. That is the copy maker’s claim, not the fridge maker’s: check the shape of the filter in your fridge before you buy.
