LG has used three main cartridge generations, and the naming is at least logical — but they still are not interchangeable, and the model ranges overlap in confusing ways.
Search by part number
Tap the number printed on your old cartridge to see current listings and prices on Amazon.ca.
LT700P and LT1000P genuine cartridges were not stocked on Amazon.ca when this page was checked. Use the search links below, or look for a certified compatible version.
Air filters too
Many LG French-door models also take a separate fridge air filter (LT120F).
Identifying yours
LG prints the part number on the cartridge. If yours is already out and unlabelled, the fridge model number — usually on a sticker inside the fresh food compartment — will identify the right filter on LG’s support site.
A note on capacity
LG rates these cartridges in gallons as well as months, and the ratings differ between generations. If your household gets through a lot of filtered water, the volume rating is the number that will run out first, not the six-month figure.
