How to Replace an LG Refrigerator Fresh Air Filter

Fresh-air and water filters do different jobs

The fresh-air filter sits in the refrigerator’s air path and helps manage cabinet odors. It does not filter dispenser water or ice. The water filter connects to plumbing and requires flushing after installation; an air filter does not.

This distinction prevents the most common shopping error. Do not buy LT1000P, LT800P, or LT700P for a Fresh Air Filter reminder. Those are water-filter families. If the display says Water Filter, use how to change an LG refrigerator water filter. If it says Fresh Air Filter, continue with this model-specific procedure.

Verify that the model uses a replaceable air filter

Find the complete model-and-serial label and open the exact LG manual. Not every LG refrigerator has the same air-filtration system. Filter location, cover style, media orientation, replacement interval, and reset buttons can differ.

Use LG support or parts information to identify the replacement by full model number. Do not shop only from the shape of a used filter or the refrigerator’s door configuration. Similar-looking compartments can use different parts.

Record the part number and model in HomeMemory before removing anything. If the manual shows no owner-replaceable fresh-air filter, do not dismantle an interior vent.

Prepare the compartment

Move food and containers away from the filter area. Use clean, dry hands and provide enough light to see alignment marks. Keep a clean bag ready for the used filter so trapped odors or dust do not spread across shelves.

Most air-filter changes do not require interacting with the water supply. Do not shut valves or open plumbing compartments for this task. If the manual calls for power control because of the exact location or procedure, follow it; otherwise avoid adding unnecessary steps.

Do not spray cleaner into the filter opening. Liquids can enter ducts, electronics, or insulation.

Open the cover by the documented motion

LG’s current guidance shows model-dependent covers that rotate or release. Note the cover’s installed position before moving it. Turn only through the marked unlock range or use the specified tabs.

If it resists, stop and use LG fresh-air filter stuck. Pliers, screwdrivers, heat, and excessive torque can crack the cover or the liner. A component designed for periodic owner service should release through normal hand pressure.

Keep track of the cover and any holder. Do not discard a reusable plastic carrier with the old media.

Remove and inspect the old filter

Observe which side faces the air path and how the media sits in its holder. Take a photograph. Remove it without shaking debris over food. Check the holder for cracks, warped clips, spills, or heavy residue.

A used filter can collect odors, but its appearance alone does not identify the source of a strong refrigerator smell. Spoiled food, a dirty drain pan, spills under drawers, packaging, and poor airflow need separate attention.

Place the old media in the prepared bag. Follow local disposal guidance and the product instructions; do not wash and reinstall a disposable filter unless LG explicitly identifies it as washable.

Install the confirmed replacement

Compare the new filter with the model-specific instructions and old media. Confirm dimensions, labeling, and orientation. Place it flat in the holder without folding, trimming, stacking, or leaving packaging attached.

Reinstall the cover or carrier and rotate it to the marked lock position. It should sit flush and secure. If it will not close with ordinary hand pressure, remove it and check orientation, packaging, and fit rather than forcing it.

Do not substitute scented sheets, loose carbon, baking-soda packets, or improvised material inside a designed filter housing. Such items can obstruct airflow or contact components.

Reset the correct indicator

The physical replacement and the display reset are separate actions. Follow the exact model’s control-panel instructions to reset Fresh Air Filter. Some models require holding a labeled button for a specified time; others use a settings menu.

Do not press Water Filter reset by mistake. That can corrupt the household’s water-filter maintenance record without affecting the new air filter. The dedicated fresh-air filter reset guide covers a light that remains on.

Record the installation date before resetting. The display tracks a maintenance interval; it does not inspect the media or remove odors.

Clean odor sources at the same time

Replacing the air filter will not remove spoiled food or a hidden spill. Discard expired items, wipe food-safe interior surfaces according to LG cleaning guidance, clean bins and shelves, and keep vents unobstructed. Avoid harsh chemicals or fragrances that can transfer taste and odor.

If the cabinet still smells, follow why an LG refrigerator smells bad. That guide separates food, spill, drain, packaging, airflow, and water-or-ice sources.

Allow the refrigerator time to circulate air after cleaning and replacement. Do not judge the result the instant the cover closes.

Establish a useful reminder

Save the refrigerator model, fresh-air-filter part, installation date, receipt, and expected next review. Keep this reminder distinct from the water filter. A household may replace both around similar times, but they are not the same maintenance event.

At reminder time, inspect current LG instructions and model status. If the refrigerator has been replaced, archive the old part mapping instead of automatically reordering it.

a product recommendation should appear only after HomeMemory independently verifies the exact product and compatibility. Until then, the official model lookup is the safer route.

When service is appropriate

Request help if the cover or holder is broken, the confirmed correct media cannot be secured, the housing is inaccessible without disassembly, or an interior vent is wet, iced, burned, or damaged. A persistent electrical or chemical odor is not a routine filter-change problem.

If the refrigerator is not cooling or airflow appears absent, use the LG refrigerator not cooling guide. Do not repeatedly replace odor media while ignoring a temperature failure.

Final Verdict

An LG fresh-air-filter change is simple only after model and part identity are clear. Keep it separate from water filtration, preserve the holder, install dry media in the documented orientation, lock the cover without force, and reset the correct reminder. Clean actual odor sources alongside the change for a result the filter can support.
