How we verify LG matches
We begin with the appliance model and associate it with the manufacturer filter family and replacement part number using official LG compatibility information as the reference.
If the model label, installed cartridge, and listed part do not agree, pause before purchasing. Our methodology explains the safeguards used throughout the guide.
Do not choose a filter solely by refrigerator appearance. Similar-looking LG refrigerators can use different cartridges.
