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.

What Your Air Filter Removes

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.

Fridge control panel

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

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: Which air filter model fits the LG LFCS27596S01?
A: The correct replacement is the LG LT120F Fresh Air Filter. It is also found under part numbers ADQ73214404 or ADQ73214408.

Q: Where is the air filter located in this refrigerator?
A: It is located on the back interior wall of the refrigerator, centered near the top. You will see a plastic cover labeled "Fresh Air Filter."

Q: How to replace LG refrigerator LFCS27596S01 air filter?
A: Replacing the air filter is a quick, tool-free process that takes less than a minute:

  1. Locate the Housing: Open the refrigerator doors and find the circular "Fresh Air Filter" cover on the back interior wall, usually located near the top.
  2. Remove the Cover: Rotate the plastic cover to the left (counter-clockwise) about a quarter-turn to unlock it and pull it away from the wall.
  3. Swap the Filter: Take out the old LT120F filter from the inside of the cover. Insert the new filter with the side labeled "FRONT" facing out toward the cover.
  4. Reinstall: Align the tabs on the cover with the wall mount, press it against the wall, and rotate it to the right (clockwise) until it snaps into place.
  5. Reset the Indicator: On the exterior control panel, press and hold the "Air Filter" button for 3 seconds until the "Replace" light disappears.
