LG uses multiple refrigerator water filter families. The appliance model is the deciding reference.
These are different filter labels
LT700P, LT800P, and LT1000P should be treated as distinct filter identifiers. A refrigerator model that uses one should not be assumed to use another.
How to choose the right one
Find the complete model number, then use the LG refrigerator filter guide or LG’s official finder. FitsMyModel only presents an exact match when the manufacturer evidence supports it.
Check the official instructions
LG’s support instructions list filter types and direct owners to the model-based finder. Use the model number and the filter label together when checking a replacement.
