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.

Where these lists come from
- LG’s own page for each refrigerator (Specs: Water Filter), checked Oct. 9, 2026
Worth knowing
LG names the filter on each refrigerator’s own page rather than on the filter’s, so this list comes from every LG refrigerator page on lg.com. Older models LG no longer has a page for are missing; your fridge’s manual names its filter.
