LG LT500P, LT600P, LT700P, LT800P, LT900X3 or LT1000P?

Start with the LT code on the old cartridge or the filter reference in the refrigerator manual. LT500P, LT600P, LT700P, LT800P, LT900X3 and LT1000P are separate families.

LG product pages also print ADQ, AGF and 5231 part numbers. Those numbers can identify the same family, but the source set does not establish that one number superseded another.

Keep the six families separate

LT900X3 is documented as a three-tier filtration bundle; the available source does not establish an exact refrigerator model. The other five families have separate cartridge pages and must still be matched to the appliance.

Use aliases only inside the named family

For example, LT800P includes ADQ73613408 and ADQ73613401, while LT1000P includes ADQ74793501 and LT1000PC. An alias from one row does not select another LT family.
