Specifications

A Reliable Match for LT800P Refrigerators

The LT800P is a model-specific LG refrigerator water filter, so the part number matters when choosing a replacement. LG identifies the filter as LT800P and lists ADQ73613408 and ADQ73613401 as associated part numbers. Checking the number on your current cartridge is a simple way to narrow down the right replacement.

Cleaner Water for Everyday Use

The filter is designed to reduce contaminants from the refrigerator's water supply, helping provide cleaner and better-tasting water from the dispenser. LG also lists reductions for substances including herbicides, chemicals, detergents, benzene, atrazine, mercury, and lead for applicable filtration claims.

The Water Goes to Your Ice, Too

Your refrigerator's ice maker uses the same filtered water supply. Keeping the LT800P within its recommended service period helps reduce unwanted tastes and contaminants before the water reaches the ice-making system.

200 Gallons or Six Months

The LG LT800P has a rated capacity of 200 gallons and is designed for replacement approximately every six months. Actual filter life can vary depending on household water consumption and the quality of the incoming water.

A Compact Filter With a Simple Fit

The LT800P measures approximately 1.73 inches in diameter and 7.28 inches long. Its twist-in installation means there is no need for special tools when changing the cartridge. LG's replacement instructions show the filter being rotated into the filter head until the alignment marks match.

NSF-Certified Filtration

LG identifies the LT800P as an NSF-certified refrigerator water filter and lists NSF/ANSI 42 and 53 certification for applicable filtration performance. This gives you a useful reference when comparing the filter with other cartridges that may look similar but are designed for different refrigerator systems.

Fits Select LG Refrigerator Models

The LT800P is used in a range of LG refrigerator models, including select side-by-side and French-door configurations. LG refrigerator specifications show LT800P as the water filtration system on compatible models such as the LSXS26366, LMXS30776, and LMXC23746. Compatibility varies by refrigerator, so your appliance model should be checked before ordering.

Replace the Filter Without Special Tools

When the filter reaches its replacement point, the old cartridge can be removed and the new LT800P rotated into the filter head. LG's instructions show a simple counterclockwise removal followed by clockwise installation until the filter and housing arrows align.

If your existing cartridge is marked LT800P, ADQ73613408, or ADQ73613401, compare that number with your refrigerator model before ordering. This helps make sure you are replacing the correct LG filtration cartridge rather than choosing a similar-looking filter from another LG series.
