Why Buy the LG LT120F Refrigerator Air Filter?

Buying a fresh LT120F on schedule is one of the simplest ways to keep your LG refrigerator smelling fresh and your stored food lasting longer. Here is what you get with a fresh LT120F air filter:

  • Activated carbon filtration targets odor-causing compounds at the source rather than masking them
  • Reduces ethylene gas released by ripening fruits and vegetables that accelerates spoilage in nearby produce
  • Keeps stored food fresher for longer by continuously reducing the airborne compounds that accelerate spoilage
  • Reduces flavor cross-contamination between strongly scented and delicate food items stored in the same compartment
  • Push-in tool-free installation completed in seconds with no specialist knowledge required
  • 6 month service life for a simple twice-yearly replacement schedule
  • Covers ADQ73214404 and ADQ73214402 so one part number confirms the correct replacement across multiple LG code variants

How do I check my current air filter part number?

The part number is printed directly on the filter currently installed in your refrigerator. The filter housing is typically located on the rear wall of the fresh food compartment. Remove the existing filter and check the label before ordering to confirm which code your unit uses.

What if my filter shows ADQ73214404 or ADQ73214402 instead of LT120F?

All three codes refer to the same filter format. If your existing filter shows ADQ73214404 or ADQ73214402, the LT120F is the correct current replacement to order. You do not need a separate filter for either of those codes.

How Often Should You Buy a Replacement LG LT120F Air Filter?

Order a fresh LT120F every 6 months regardless of usage level. Air filters reach adsorption capacity based on time and exposure rather than a measurable throughput like water filters. Waiting for noticeable odors before buying a replacement means the filter has already been operating past its effective service life for some time. Ordering on the 6 month schedule maintains a consistently fresh refrigerator environment year round.

How to Install the LG LT120F Refrigerator Air Filter

  1. Locate the air filter housing on the rear wall of the LG refrigerator fresh food compartment
  2. Press the release tab to disengage the old LT120F filter from the housing slot
  3. Pull the old filter straight out
  4. Remove the new LT120F filter from its packaging
  5. Push the new filter firmly into the housing until it clicks securely into place
  6. No flushing or water line reset is required after installation
  7. Note the installation date and schedule your next order at the 6 month mark

FAQs

Where can I buy the LG LT120F refrigerator air filter?

You can order the LG LT120F directly from the shop link on this page. Confirm the part number against your existing filter label before completing your purchase to ensure you are ordering the correct filter for your model.

Is the LG LT120F the same as ADQ73214404 or ADQ73214402?

Yes. ADQ73214404 and ADQ73214402 are alternative part numbers that refer to the same LT120F filter format. If your existing filter shows either of those codes, the LT120F is the correct current replacement to order.

Does the LG LT120F need any preparation before installation?

No preparation is required. Remove the new filter from its packaging and push it directly into the housing. Activated carbon begins working immediately with no soaking, flushing, or break-in period required.

Will replacing the LT120F on schedule actually make a difference to food freshness?

Yes. A fresh activated carbon filter continuously reduces ethylene gas inside the refrigerator compartment. Produce stored near a fresh filter spoils more slowly because ethylene buildup is being actively reduced rather than allowed to accumulate. Replacing on the 6 month schedule maintains this benefit consistently.

My LG refrigerator still smells after replacing the LT120F — what should I check?

The LT120F reduces airborne odor compounds but does not remove odors embedded in refrigerator surfaces or food containers. Wipe down interior surfaces, remove any spoiled food, and allow 24 to 48 hours for the new filter to reach full adsorption capacity before concluding there is an issue with the filter itself.

How is the LG LT120F different from the LG LT1000P water filter?

The LT120F is an air filter that reduces odors and ethylene gas inside the refrigerator compartment. The LT1000P is a water filter that reduces contaminants in dispensed water and ice. They serve completely different functions and are not interchangeable. Some LG refrigerator models require both.
