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 600 gallons, so a household drawing more than about 1.1 gallons a day through the fridge runs it out sooner.

Which refrigerators it fits
Waterdrop says it replaces LT1000P, LT1000PC, LT1000PCS, MDJ64844601, ADQ74793501, ADQ74793502, 46-9980, 9980 (Waterdrop’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.
