LG Filter Family Note: LG makes several different water filter models — LT500P, LT600P, LT700P, LT800P, and LT1000P — and they are NOT interchangeable. Each fits different refrigerator models. Always check the part number on your current filter or your refrigerator model number before ordering.

Product Description

The LG LT800P is a replacement water filter designed for LG's premium side-by-side and large-capacity French door refrigerators. Certified by NSF International to Standards 42 and 53, this filter delivers clean, fresh-tasting water and ice by reducing chlorine taste, odor, sediment, particulates, and other contaminants commonly found in tap water.

The LT800P features a horizontal cartridge installation — the filter slides in horizontally into the housing rather than twisting or pushing upward. The housing is typically located in the upper right area inside the refrigerator compartment. The filter should be replaced every 6 months or after 200 gallons for optimal performance.

Installation Instructions

Important — Horizontal Installation: The LT800P slides in horizontally into the filter housing. It does not use a quarter-turn twist like most refrigerator filters. Read all steps before installing.
  1. Locate the Filter Housing: The filter is located in the upper right area inside the refrigerator compartment. The housing has a cover or door that opens to expose the filter cartridge
  2. Open the Filter Cover: Open or lower the filter housing cover to expose the cartridge
  3. Remove Old Filter: Pull the old filter straight out horizontally from the housing. No twisting is required
  4. Prepare New Filter: Remove the protective cap from the new filter cartridge. Ensure the O-rings are seated correctly in their grooves
  5. Install New Filter: Align the new filter with the housing and slide it straight in horizontally until it seats firmly. Do not twist
  6. Close the Cover: Close or raise the filter housing cover until it clicks into place
  7. Flush the System: Run water through the dispenser for approximately 3 gallons (around 5 minutes) to flush air and activate the carbon block. Water may appear slightly cloudy initially — this is normal
  8. Discard Initial Ice: Discard the first batch of ice produced after installation
  9. Reset Filter Indicator: Press and hold the filter reset button on your LG refrigerator's control panel until the indicator resets. Refer to your owner's manual for the specific procedure for your model
? Installation Tip: If water leaks after installing the new filter, the most common cause is an O-ring that is not seated correctly in its groove. Remove the filter, check that both black rubber O-rings at the top of the cartridge are properly positioned, then reinstall. Do not overtighten or force the filter.

Frequently Asked Questions

How do I know if my LG refrigerator uses the LT800P and not another LG filter?

Check the part number printed on your current filter. If it reads LT800P, ADQ73613401, or ADQ73613408, this is the correct replacement. The LT800P is used in LG's premium side-by-side and large-capacity French door models (LMXC, LMXS, LSXS, LSXC, LNXC, LNXS, LPXS, LUPXS series). LG makes several filter models and they are not interchangeable — always verify your filter's part number before ordering.

Are LT800P, LT800PC, and LT800PCS the same filter?

Yes. LT800P, LT800PC, and LT800PCS are all the same filter. The letter suffixes indicate minor packaging or color variations rather than different products. All are fully interchangeable and fit the same refrigerator models.

Why is water leaking after I installed the new LT800P filter?

The most common cause is an O-ring that has shifted out of its groove during installation. Remove the filter and check that both black rubber O-rings at the top of the cartridge are properly seated in their grooves before reinstalling. Also ensure the filter is fully and evenly inserted into the housing — an uneven fit can cause leaks even with correct O-ring placement.

Is the LT800P compatible with Kenmore refrigerators?

Yes. Select Kenmore refrigerators sharing LG's manufacturing platform use the LT800P under Kenmore part numbers 46-9490, 9490, and 469490. Check the label on your current Kenmore filter to confirm before ordering.

Where is the LT800P filter located in my refrigerator?

The LT800P filter is located in the upper right area of the refrigerator compartment, behind a cover or door. Unlike most LG filters, it installs horizontally — slide it straight in rather than twisting to lock. Refer to your owner's manual for the exact location and cover design in your specific model.
