How to Know If LG LT120F Is the Right Refrigerator Air Filter for Your Model

LG refrigerators are known for their stylish design, innovative features, and excellent food preservation technology. However, many owners get confused when it comes to replacing the air filter. If you have seen LT120F or “LG LT120F” while searching for a new air filter, this detailed guide will help you determine whether this is the correct filter for your refrigerator.

This informational blog post explains compatibility, features, installation, maintenance tips, and common mistakes so you can keep your LG refrigerator smelling fresh and clean.

Why LG Air Filter Numbers Can Be Confusing

LG uses different air filter models across their refrigerator lineup:

• Older LG models may use different air filter types.
• Many newer French Door and Side-by-Side models use the LT120F.
• Some listings show multiple compatible part numbers or cross-references.
• LG InstaView and Door-in-Door models often require the LT120F specifically.
• Third-party sellers sometimes list similar-looking filters that may not perform the same.

Using the wrong air filter can result in poor odor control or the filter not fitting properly in the designated compartment.

Where to Find Your LG Air Filter Model Number

Identifying the correct air filter is straightforward. Follow these steps:

1. Check the old filter — Open the air filter compartment and look for LT120F printed on the label. This is the most reliable method.
2. Inspect the filter housing — The LT120F is typically located at the top of the fresh food compartment, often behind a small cover or grille.
3. Review your refrigerator manual — Search for “air filter,” “LT120F,” or “odor filter.”
4. Locate the model plate — Inside the refrigerator (usually on the left or right wall). Use your full LG model number to verify compatibility.
5. Use LG’s official parts lookup — Visit the LG website and enter your refrigerator model number.

Many LG refrigerators have a filter replacement indicator or notification on the display panel.
