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 300 gallons, so a household drawing more than about 1.6 gallons a day through the fridge runs it out sooner.

Which refrigerators it fits
Filters Fast says it replaces MWF (Filters Fast’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.
Worth knowing
Filters Fast is a filter retailer, and this is its own brand. It charges less each for three or more.
