The LT800P sits between the LT700P and LT1000P in LG's line-up and is fitted to a number of 2016-and-later French door models, including several InstaView builds.
About this cartridge
The filter uses the ADQ73613401 part number, with ADQ73613402 as the later revision. It carries the full three-standard certification set (42, 53 and 401), which puts it alongside the LT1000P rather than the LT700P.
Housing compatibility is the confusing part. LG moved between three cartridge designs during the same model years, and refrigerator model numbers do not encode which one was fitted — the same series can appear with either an LT800P or an LT1000P depending on build date. The only reliable check is the cartridge currently in the housing.
Rated at 200 gallons or six months, same as the rest of the LT family.

These part numbers refer to the same physical cartridge. If the number on your old filter is in this list, this is the right replacement.
Not a substitute for LT1000P despite the similar length. The head collar diameter differs by about 2 mm.
Which refrigerators it fits
LG has not published a model-level list for this cartridge that we can verify, so we do not publish one either. The number on the cartridge you are removing is the reliable check.

- Turn the old cartridge a quarter turn counter-clockwise and pull it straight out. Keep a towel under it — a few ounces of water will come out.
- Remove the protective cap from the new cartridge and check that the O-rings are seated flat in their grooves.
- Push it in and turn clockwise until it stops. Run two to three gallons through the dispenser to flush carbon fines, then reset the indicator.
