How to Change an LG Refrigerator Air Filter: A Complete Step-by-Step Guide
Changing the air filter in your LG refrigerator is a simple five-minute maintenance task that is critical for ensuring your food stays fresh and your appliance runs efficiently. You should replace the filter every six months. The process involves locating the filter compartment, removing the old filter, installing the new one, and resetting the filter indicator light. This guide provides detailed, model-specific instructions to make the process effortless.
Why Changing Your Refrigerator's Air Filter is Essential
The air filter inside your LG refrigerator is not for the appliance's cooling system; its primary purpose is to clean the air that circulates inside the fresh food compartment. This circulation is key to preserving the quality of your stored food and beverages. A fresh filter actively scrubs the air of odors and captures microscopic particles. Over time, the filter becomes saturated with the contaminants it collects. A clogged, old filter cannot perform its job effectively. Neglecting to change the filter leads to several negative consequences. The most immediate effect is the reduction in air quality inside the refrigerator. Without a clean filter, odors from strong-smelling foods like onions, cheese, and fish can permeate other items, leading to flavor transfer. Your milk might taste like onions, and your strawberries could absorb the aroma of leftover pizza. Furthermore, a saturated filter restricts airflow within the compartment. This can create uneven cooling, with some areas becoming warmer than others, which compromises food safety and can lead to premature spoilage. Finally, a struggling air circulation system can cause the refrigerator's fans to work harder, potentially leading to increased energy consumption over time. Regularly replacing the filter is a small investment that pays off in fresher-tasting food, optimal appliance performance, and peace of mind.
Identifying the Correct LG Refrigerator Air Filter
Using the correct replacement filter is the first and most important step. LG manufactures filters designed specifically for their refrigerators, and using a genuine OEM (Original Equipment Manufacturer) filter is highly recommended. These filters are engineered to meet the exact specifications of your appliance, ensuring perfect fit, optimal airflow, and certified filtration performance. Using a generic or incorrect filter can lead to air leaks, poor filtration, and potentially damage the filter housing.
To find the correct filter, you have several options. The most reliable method is to check the model number of your LG refrigerator. This number is usually located on a sticker inside the main refrigerator compartment, often on the side wall, the ceiling, or on the door frame. Once you have the model number, you can visit the LG website or check with appliance parts retailers, both online and in-store, to find the compatible filter. You can also take the old filter with you to a store. The model number of the filter itself is printed directly on its housing. Common LG filter models include LT1000P, LT800P, LT700P, and LT600P. If your refrigerator has a water and ice dispenser, it will also have a separate water filter. It is crucial not to confuse the air filter with the water filter. They are different parts with different functions and locations. The air filter is typically a white or gray cartridge, while water filters are often located in the grille at the bottom of the refrigerator or inside the fresh food compartment.
Preparation and Tools Needed
Changing an LG refrigerator air filter requires minimal preparation and no specialized tools. You will not need a screwdriver, pliers, or any other implements. The entire process is designed for tool-free replacement.
Required Items:
- New LG Air Filter: Ensure you have the correct replacement filter, as discussed in the previous section.
- 5 Minutes of Your Time: The actual replacement takes only a few moments.
Before you begin, it is a wise safety practice to unplug the refrigerator from the wall outlet. This eliminates any remote risk of electrical shock. If unplugging the unit is inconvenient, you can ensure the control panel is locked (if your model has a control lock feature) to prevent accidental activation while you are working. You may also want to have a cloth handy to wipe out the filter compartment if any dust has accumulated.
Step-by-Step Guide to Changing the Filter
The location of the air filter compartment varies slightly depending on your LG refrigerator model. The two most common locations are on the ceiling of the fresh food compartment or on the rear wall.
For Ceiling-Mounted Filters:
- Locate the Compartment: Look up at the ceiling of the refrigerator interior. You will see a rectangular panel or a clearly defined cover.
- Open the Cover: Press the latch or tab on the cover and gently push it open. The cover will typically swing down or pivot open.
- Remove the Old Filter: The old filter will be sitting in a slot. Grasp it and pull it straight down and out. Note the orientation of the filter; it may have arrows indicating the direction of airflow.
- Unpackage the New Filter: Remove the new filter from its packaging. Most new filters have a protective cover or tape over the grille. Peel this off before installation.
- Install the New Filter: Insert the new filter into the slot, aligning it in the same orientation as the old one. Push it firmly into place until it is seated correctly.
- Close the Cover: Swing the compartment cover back up until it clicks or locks into place.
For Rear-Wall Mounted Filters (often behind a vented panel):
- Locate the Grille: Find the vented panel on the rear wall inside the refrigerator.
- Remove the Grille: This panel usually snaps in place. Gently pull the top of the grille forward to unclip it, then lift it away.
- Remove the Old Filter: The filter will be visible behind the grille. Pull it straight out.
- Install the New Filter: After removing the protective cover from the new filter, slide it into the slot, ensuring it is oriented correctly.
- Replace the Grille: Snap the vented grille back onto the rear wall.
How to Reset the "Replace Filter" or "Air Filter" Indicator Light
After installing the new filter, it is crucial to reset the indicator light on your refrigerator's control panel. This light is not automatically connected to the physical filter; it is a timer that reminds you to perform the replacement. Resetting it ensures you get accurate reminders in six months.
The reset procedure is generally consistent across most LG refrigerator models:
- Locate the "Filter Reset" button on the control panel. This button may be a dedicated physical button or a touch-sensitive icon on a digital display. It is often labeled with the word "Filter" or an icon of a water droplet or leaf.
- Press and hold the "Filter Reset" button for approximately 3 to 5 seconds.
- You will see the indicator light change. It may turn off, change from red or orange to blue, or a counter will reset to 100%. This confirms the reset is successful.
If your model does not have a dedicated button, the reset function is often accessed through the settings menu. Navigate the menu options using the buttons or touchscreen to find the "Filter Reset" option and select it. If you cannot find the reset instructions, consult your refrigerator's user manual, which can usually be found online on the LG website by searching with your model number.
Troubleshooting Common Issues
Even a simple task can sometimes present minor challenges. Here are solutions to common problems.
- The new filter won't fit. Double-check that you have the correct filter model for your refrigerator. Also, ensure you are trying to install it in the correct orientation. The filter is designed to fit only one way.
- The filter compartment cover won't close. This almost always means the filter is not fully seated. Remove the filter and reinsert it, making sure it is pushed all the way into the slot.
- The "Replace Filter" light won't reset. First, ensure you are holding the correct button for a full 3-5 seconds. If it still does not reset, try unplugging the refrigerator from the wall for one minute, then plugging it back in. This can sometimes reset the control board. Then attempt the reset procedure again.
- The filter compartment is dirty. Use a damp cloth to wipe out the empty compartment before inserting the new filter. Avoid using harsh chemicals or abrasive cleaners.
Frequently Asked Questions (FAQ)
How often should I change my LG refrigerator air filter?
LG recommends replacing the air filter every six months. However, if you store particularly strong-smelling foods frequently, you may consider changing it more often, perhaps every four to five months.

No. LG refrigerator air filters are not designed to be cleaned and reused. They contain materials like activated carbon that become saturated with odors and particles. Attempting to clean it with water or vacuuming will ruin the filtering media. They are disposable and must be replaced.
What is the difference between an air filter and a water filter?
The air filter cleans the air inside the refrigerator to control odors and keep food fresh. The water filter cleans the water that goes to the ice maker and water dispenser, removing sediments, chlorine, and other contaminants for better-tasting water and ice. They are separate parts with separate replacement schedules.
Where can I buy genuine LG air filters?
Genuine LG air filters can be purchased from the LG online store, major appliance retailers, home improvement stores like Home Depot or Lowe's, and online marketplaces like Amazon. Always verify that the seller is an authorized LG parts distributor to ensure you are getting an authentic product.
My refrigerator doesn't have a "Replace Filter" light. How do I know when to change it?
If your model lacks an indicator, you should still replace the air filter every six months. A good practice is to note the installation date on a piece of masking tape directly on the filter or set a reminder in your phone's calendar for six months in the future.
By following this comprehensive guide, you can confidently maintain your LG refrigerator, ensuring it continues to provide fresh, great-tasting food for you and your family.
