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
Instapure says it replaces LT800P, ADQ73613401, 469490, 9490, ADQ73613402 (Instapure’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
Instapure’s page says 200 gallons; the NSF listing rates it at 300, which is used here.
