LG Water Filter Finder

By Neo Pecorro, Founder · Last updated August 25, 2026

LG makes several refrigerator water filters across its lineup — LT600P, LT700P, LT800P, and LT1000P are all current, real LG filter numbers used on different model generations. This page currently covers LT700P and LT1000P, the two most common filters across LG’s French-door and side-by-side lineup, and they are not interchangeable with each other — wrong one and the cartridge either won’t seat or won’t be recognized. FilterFitNow verifies each match against manufacturer part-fitment data and independent retailer cross-references, not just similar-looking part numbers.

Which LG Filter Do You Need?

Both LT700P and LT1000P use a similar twist-to-remove quarter-turn cartridge design, so housing shape and location won’t reliably tell them apart. If you can see the old filter, the part number printed on it is the definitive answer.

LT1000P / LT1000PC / LT1000PCS	ADQ74793501	LFXS26973, LFXS28968, LFXC22526, LFXC24796, LMXC23796, LRFVS3006, LRMDS3006, LRMXS2806 series	LG LT1000P Guide

Some model ranges overlap in production years, so the refrigerator model number alone can be ambiguous — the filter housing design and the part number printed on your existing cartridge are the two reliable checks. If your model isn’t listed in either row above, check the part number on your current filter directly rather than guessing from your fridge’s model number, since LG reused ranges inconsistently across years.

Frequently Asked Questions

How do I know if I have an LT700P or LT1000P filter?

Check the part number printed on your current filter — ADQ36006101 is LT700P, ADQ74793501 is LT1000P. Both use a similar twist-to-remove design, and housing location varies by refrigerator model, so the part number is the most reliable way to tell them apart. If you can’t read the old filter, check your refrigerator’s model number against the compatible-series table above.

Are LT1000P, LT1000PC, and LT1000PCS the same filter?

Yes, functionally. LT1000PC and LT1000PCS are updated packaging and revision variants of the same LT1000P filter (ADQ74793501) and are interchangeable for compatible models.

Can I use an LT700P in a refrigerator that takes LT1000P, or vice versa?

No. The two use different part numbers and are sized for different housings, so they are not interchangeable even though both are LG filters and both use a similar twist-to-remove design. Installing the wrong one won’t seat properly.

My LG refrigerator model isn’t listed in the table above — what should I do?

Check the part number printed directly on your existing filter rather than relying on your refrigerator’s model number alone, since LG used both filters across model years inconsistently. If the code on your old filter matches ADQ36006101 or ADQ74793501, it’s confirmed compatible regardless of whether your specific model appears in the table. If it doesn’t match either code, your fridge likely takes LT600P or LT800P instead — LG filters this page doesn’t cover yet.

Sourcing and verification for both filters follows the same methodology used across FilterFitNow’s brand guides — manufacturer part-fitment data cross-referenced against independent retailer listings. See the LT700P and LT1000P guides linked above for full sourcing detail.
