The LG refrigerator air filter LT120F helps keep your fridge smelling fresh by reducing common food odors from leftovers, fruits, vegetables, dairy, and everyday stored items. Instead of letting strong smells spread inside the fridge, this filter helps support cleaner air and a fresher food storage space.

Replacing the LG air filter LT120F is quick and simple. Just remove the old filter from the air filter compartment and place the new one in its position. For best results, replace it every 6 months or when your refrigerator shows a filter replacement reminder. An LG fresh air filter is a small but useful part of regular fridge care. It helps your refrigerator feel cleaner, keeps odors under better control, and makes opening the fridge more pleasant every day.

Why Replace Your LT120F Air Filter?

Your LG refrigerator's fresh air filter plays a crucial role in maintaining food quality and freshness. Over time, the filter becomes saturated with odor-causing particles and loses its effectiveness. Regular replacement ensures:

Elimination of strong food odors from onions, garlic, fish, and other pungent items
Prevention of odor transfer between different foods
Optimal air circulation throughout your refrigerator
Extended freshness of fruits, vegetables, and other perishables
A cleaner, more pleasant refrigerator environment

Installation Instructions

Locate the fresh air filter housing in your LG refrigerator (typically in the upper right corner of the fresh food compartment)
Remove the old filter by gently pulling it out or pressing the release tab
Unwrap your new filter
Insert the new filter into the housing until it clicks into place
Reset the filter indicator light on your refrigerator control panel (if equipped)

When to Replace Your LT120F filter

LG recommends replacing your filter every 6 months for optimal performance. However, you may need to replace it sooner if you notice persistent odors, reduced food freshness, or if your filter indicator light is on. Learn how often to replace your LG refrigerator air filter for best results.

Also Compatible With Kenmore

The filter is also a direct replacement for select Kenmore Elite refrigerators using the Kenmore 9918 / 46-9918 air filter. Same dimensions, same carbon filtration — fully interchangeable.

Don't Forget Your Water Filter

Keeping your fridge air fresh is just one part of complete refrigerator maintenance. Pair this air filter with the right LG refrigerator water filter to ensure both your air and water stay clean and fresh year-round.

LT120F is also compatible with select Kenmore Elite refrigerators using 46-9918, 469918, or 9918 air filters.

How It Works

The air filter uses activated carbon technology to continuously circulate and purify the air inside your refrigerator — neutralizing odors from foods like fish, leftovers, and produce before they spread or affect flavor.

Activated Carbon Core: Uses a dense carbon matrix to adsorb odor molecules and gases on contact.
Continuous Air Circulation: Works with your fridge's fan to pull air through the filter repeatedly, 24/7.
Adsorption Technology: Traps contaminants at a molecular level rather than just masking smells.
Passive Filtration: Requires no maintenance between replacements—install, and it works automatically.

Why It Matters

Odor Control

Prevents food odors from spreading and mixing inside your refrigerator.

Freshness Protection

Removes ethylene gas that accelerates the spoilage of fruits and vegetables.

Food Safety

Inhibits airborne bacteria and mold spores from contaminating stored food.

Why It Matters — Fresh Refrigerator Interior

What This Filter Removes

Our certified filtration system targets and removes a wide range of harmful contaminants and odors.

Food Odors: Neutralize strong smells from fish, leftovers, onions, and other pungent foods.
Ethylene Gas: Absorbs the natural gas emitted by ripening produce that speeds up spoilage
Airborne Bacteria: Captures and reduces bacteria circulating in the air inside your fridge.
Mold Spores: Filters out mold spores before they can settle and grow on stored food
Volatile Organic Compounds (VOCs): Remove harmful chemical compounds that can affect food quality.
Cross-Contamination Particles: Prevents flavor and odor transfer between different food items.

When to Replace Your Refrigerator Air Filter

Every 6 Months

Activated carbon saturates over time. Replacing every 6 months ensures continuous odor and gas adsorption — even if the filter looks clean.

Filter Alert Light

When your fridge's air filter indicator turns red or begins flashing, replace immediately. The sensor tracks usage and airflow performance automatically.

Persistent Fridge Odors

If odors linger inside a clean fridge, your air filter is exhausted. Don't wait for the indicator — trust your nose and replace it promptly.

FAQ

Q: How often should I replace the LG refrigerator air filter LT120F?
A: LG recommends replacing the filter every 6 months for optimal performance. However, if you notice persistent odors or reduced freshness, you may need to replace it sooner. See our LT120F replacement timing guide for more details.

Q: Is the Kenmore filter 9918 compatible with the LG LT120F?
A: LG manufactures many of Kenmore's Elite French door and side-by-side refrigerators; these two filters share the same physical dimensions and carbon-filtration specifications. You can use them interchangeably without any issues. Shop the Kenmore 9918 / 46-9918 air filter if that's what your fridge calls for.

Q: How to replace the LG air filter LT120F?
A: Replacing the filter is a quick, tool-free process. The filter housing is located at the top back wall of your refrigerator interior, usually labeled "Fresh Air Filter."

Remove the cover: Grip the outside of the plastic cover firmly. Rotate it counterclockwise about a quarter-turn to release the plastic tabs from the back wall, then pull it straight forward.
Swap the old filter: The old filter sits snugly inside the back of the cover. Pop it out by pulling it away from the cover. Place the new filter into the cover with the side labeled "FRONT" facing outward (so you can read it when looking into the cover).
Reinstall the housing: Align the four small tabs on the back of the cover with the hooks on the refrigerator wall. Push it flush against the wall and rotate it clockwise until it clicks firmly into place.
Reset the status light: Locate your refrigerator control panel. Find the Air Filter button and press and hold it for 3 seconds until the replace light turns off or resets to its default status.

Note: If your model features a Power / Max mode setting next to the filter status, resetting the sensor will also return the fan speed to its regular, efficient auto-cycling schedule.

Q: Do I need any tools to install this filter?
A: No tools are required. The filter features a simple snap-in design that allows for quick and easy installation in seconds.

Q: Can I clean and reuse the LT120F air filter?
A: No, the filter is designed as a disposable filter and cannot be effectively cleaned or reused. For best results, replace it with a new filter every 6 months.

Q: Is this a genuine LG filter or an aftermarket replacement?
A: This is a genuine OEM LG replacement filter, ensuring the highest quality and perfect fit for your LG refrigerator.

Q: What's the difference between a fresh air filter and a water filter?
A: A fresh air filter removes odors from the air inside your refrigerator, while a water filter purifies the water and ice dispensed by your refrigerator. Both are important for optimal refrigerator performance. If you also need a water filter, check out the LG LT1000P water filter — one of the most popular LG water filter replacements.
