LG refrigerator water filters

LT-series cartridges in French door, side-by-side and bottom-freezer models.

A lg fridge water filter replacement is decided by the housing, not the model year: every refrigerator built on the same housing takes the same cartridge, which is why a single part number such as LT1000P can cover 40 models. The list below pairs all 40 LG models in this reference set with the cartridge each one takes.

Which LG fridge water filter do I need?

Pull the cartridge currently in the housing and read the number on its face — that is the part you need. If the housing is empty, find the model sticker inside the fresh-food compartment and look the model up — LG ThinQ models included, see LG ThinQ water filter replacement; the most common cartridge in this set is LG LT1000P, which fits 40 models. Part numbers are cross-referenced above, so an old box marked with a different code can still be the same cartridge.

Common questions

What water filter does my LG refrigerator take?
LG uses several filter housings, so the cartridge is set by the model number rather than the brand alone. In this reference set the most widely used is LT1000P (40 models). Look your model up under Refrigerators above, or read the number printed on the cartridge you are removing.
Are LG refrigerator water filters interchangeable?
Only within the same housing. Two cartridges with different part numbers can be the same physical part when they share a housing family — those cross-references are listed on each cartridge page. A cartridge from a different housing will not seal, even if it looks similar.
How do I find my LG filter part number?
Two places: the model sticker inside the fresh-food compartment, or the face of the cartridge currently installed. The cartridge number is the definitive one, because manufacturers change suppliers mid-model-year without changing the refrigerator model code.
