LG Refrigerator Water Filters
LG refrigerators use the LT-series cartridges — LT500P, LT600P, LT700P and LT800P — plus the parallel ADQ part numbering that causes half the confusion in LG filter shopping.
Type it — e.g. LFXS26973S — and the Filter Finder shows the exact filter for your fridge and its best price. The model plate sits inside the refrigerator compartment, left wall or kickplate area.

The LG filter system at a glance
| Bay / system | Part numbers | Models in fit library | |
|---|---|---|---|
| LT600P the most common LT line | LT600P · ADQ36006101 | 117 | |
| LT700P | LT700P · ADQ36006102 | 75 | |
| LT500P | LT500P · ADQ73310908 | 56 | |
| LT800P higher-capacity variant | LT800P · ADQ73213404 | 28 | |
| LT1000P newer slim line | LT1000P | 14 |
Counts from the verified fit library. LT and ADQ codes pair one-to-one — the LT number is the consumer code, the ADQ number the service code; either listing is the same cartridge. 2025+ models: check the notch note on your model page.
LG Models by Number
Every LG-family refrigerator model below has a dedicated fit page — exact cartridges that fit, filter location, and change interval. Kenmore 795-series twins are the single largest block in the library and file under their own model strings. The model number is the short alphanumeric string printed on the rating plate inside your fridge (not the serial number). Browse by first character, or jump straight to your model with the Filter Finder.

How to Find Your LG Model Number
On most LG units the rating plate is inside the refrigerator compartment — left wall near the crisper drawers, behind the lower kickplate, or on the door frame where the hinges sit. The model number is a short alphanumeric code (the longer string is the serial number, which you do not need). LG strings open with L: LFX is the French-door flagship line, LRS and LSC side-by-side, LMX the multi-door cabinets. A string starting with 795 is the Kenmore catalog code for an LG-built machine — the single biggest block in our library — and it takes the identical LT cartridge. Numbers like LT700P or ADQ74793501 are filter part numbers — those go in the finder, not the A–Z index.
LG Water Filter FAQ
Nearly all LG fridges with internal filtration use one of four LT-series cartridges — LT500P, LT600P, LT700P or LT800P — chosen by model family rather than by year. The LT600P covers the largest fleet (117 models in our library). Each LT code has an ADQ service twin (LT600P = ADQ36006101), so a parts listing under either number is usually the same cartridge. Type your model number into the finder for the exact variant — including the 2025 notch flag where it applies.
On tank-fed models produced from 2025 onward, LG re-cut the cartridge locking notch. Cartridges manufactured to the new spec seat in both old and updated bays, but some older-pattern generics won’t lock into the new bay — the cartridge slips or pops free under line pressure. If your LG was built in 2025 or later, or a previous “compatible” cartridge stopped fitting after a bay service, check the notch note on your model page before reordering. This is a mechanical fit issue, not a chip or authentication change — LG has no RFID lock on any LT line.
Yes. The 795 prefix on a Kenmore model number means LG manufactured the unit for Sears, and the water filtration is pure LG — same LT-series bays. The famous mappings: Kenmore 46-9990 resolves to LT600P, and the 46-9956/9954 generation to the LT500P family. Our library includes the Kenmore 795-series twins. Search the Kenmore number or the LG twin — both land on the same cartridge page, and the fit verification is identical.
LG specifies a 6-month replacement cycle across the LT series, with capacity varying by cartridge — the LT600P family carries a higher gallon rating than the LT500P, which is why the same fridge family can list different numbers. The panel indicator counts elapsed time, not gallons. Ice-heavy or hard-water households should shorten to 5 months; the first symptom of an exhausted LG cartridge is usually slow dispensing flow as the media compacts, followed by chlorine taste in the ice.
Almost always yes. LG runs two numbering systems on one cartridge: the LT code is the retail-facing number, the ADQ code the service/parts-department code. LT600P and ADQ36006101 refer to the same part, LT700P pairs with ADQ36006102, LT500P with ADQ73310908. The trap is listings that quote an ADQ number with a different suffix generation — suffixes like -01 versus -02 can indicate packaging or revision changes. Match by your refrigerator model in the finder and both codes resolve to the same verified cartridge.
Yes — type LT500P, ADQ74793501 or any number printed on the old cartridge into the Filter Finder and it reverse-looks-up every LG-family refrigerator that cartridge fits, Kenmore 795 twins included.
