How to Turn Off Clean Filter on LG Air Conditioner
If you’ve ever been in the middle of a hot summer day, enjoying cool air from your LG air conditioner, only to have it suddenly stop working because of a “Clean Filter” alert, you’re not alone. The Clean Filter feature is designed to keep your AC running efficiently by reminding you when the air filter needs attention. While this is a helpful safety and maintenance tool, there are times when you may want to turn it off—especially if you’ve already cleaned the filter but the system hasn’t recognized it, or if you’re performing routine maintenance and don’t want the unit to shut down unexpectedly.
In this comprehensive guide, updated for 2026, we’ll walk you through exactly how to turn off the Clean Filter function on your LG air conditioner. Whether you’re using a standard remote, a smart model with Wi-Fi connectivity, or the latest LG ThinQ app, we’ve got you covered. You’ll learn step-by-step instructions, practical tips, troubleshooting advice, and important reminders about maintaining your unit for long-term performance.
By the end of this guide, you’ll know not only how to disable the Clean Filter alert but also when it’s safe to do so—and why you shouldn’t leave it off permanently. Let’s get started!
What Is the Clean Filter Feature on LG Air Conditioners?
Before diving into how to turn it off, it’s important to understand what the Clean Filter feature actually does. Introduced in many LG air conditioner models over the past decade, this smart function monitors airflow and filter condition. When dust, pet dander, or debris builds up on the air filter, it restricts airflow. The AC unit detects this drop in performance and triggers a “Clean Filter” alert on the display or remote control.
Once activated, the alert may:
– Flash a light on the indoor unit
– Display a message on the remote or control panel
– Pause cooling or heating until the filter is cleaned and the system is reset
This feature helps prevent overheating, reduces strain on the compressor, and maintains indoor air quality. It’s especially useful for people with allergies or pets, as it ensures the filter is changed regularly.
However, the system isn’t perfect. Sometimes, the sensor may trigger a false alarm—especially after a recent cleaning—or you may be performing maintenance and need the AC to run without interruption. That’s when knowing how to turn off the Clean Filter function becomes essential.
Why You Might Want to Turn Off the Clean Filter Alert
There are several valid reasons why you might want to temporarily disable the Clean Filter feature:
- You’ve already cleaned the filter: After cleaning, the system may not immediately recognize the change. Turning off the alert lets you resume normal operation without waiting for a reset cycle.
- Performing maintenance: If you’re cleaning the coils, checking refrigerant levels, or servicing the unit, you may need the AC to run continuously without interruptions.
- Testing the system: Technicians or homeowners may want to test airflow or cooling performance without the filter alert interfering.
- False alarms: In rare cases, the sensor may malfunction or be overly sensitive, triggering alerts even with a clean filter.
- Remote operation needs: If you’re using the AC in a rental property or guest room and want to avoid frequent alerts, you may choose to disable the feature temporarily.
That said, it’s crucial to remember that turning off the Clean Filter alert should only be a temporary measure. Leaving it disabled long-term can lead to reduced efficiency, higher energy bills, and poor air quality. Always re-enable the feature once your task is complete.
How to Turn Off Clean Filter Using the Remote Control
Most LG air conditioners allow you to manage the Clean Filter function directly from the remote. Here’s how to do it step by step.
Step 1: Power On the Air Conditioner
Make sure your LG air conditioner is turned on and running. The remote must be able to communicate with the indoor unit. If the unit is off, press the Power button on the remote to turn it on.
Step 2: Access the Menu or Settings
Look for a button labeled Menu, Settings, or Function on your remote. This is usually located near the center or bottom of the remote. Press it to open the main menu.
Tip: On some newer models, you may need to press and hold the Filter or Clean button for 3–5 seconds to access filter-related settings.
Step 3: Navigate to the Filter or Clean Filter Option
Use the arrow buttons (▲/▼ or ◄/►) to scroll through the menu options. Look for entries like:
– “Filter Reset”
– “Clean Filter”
– “Filter Alert”
– “Maintenance”
Select the option related to the filter. On some models, you may see a toggle for “Clean Filter On/Off.”
Step 4: Turn Off the Clean Filter Alert
Once you’ve highlighted the Clean Filter setting, press the OK or Enter button. If there’s a toggle, switch it to “Off.” You may see a confirmation message like “Clean Filter Disabled” or “Alert Off.”
Note: On certain models, turning off the alert may also require you to reset the filter timer. Follow any on-screen prompts to complete the process.
Step 5: Exit the Menu
Press the Back or Exit button to leave the menu. The Clean Filter alert should now be disabled, and your AC will continue running without interruption.
Example: On an LG Dual Inverter model from 2025, the process looks like this: Press Menu → Scroll to “Filter” → Select “Clean Filter Alert” → Toggle to “Off” → Confirm.
How to Turn Off Clean Filter Using the LG ThinQ App (2026 Models)
If your LG air conditioner is Wi-Fi enabled and compatible with the LG ThinQ app (available for iOS and Android), you can control the Clean Filter function remotely. This is especially convenient for smart homes or if you’re away from the unit.
Step 1: Ensure the AC Is Connected to Wi-Fi
Open the LG ThinQ app on your smartphone. Make sure your air conditioner is listed and shows as “Online.” If not, follow the app’s setup guide to connect your AC to your home Wi-Fi network.
Tip: Most 2024–2026 LG smart AC models support Wi-Fi out of the box. Check your model number (usually on the side or back of the indoor unit) to confirm compatibility.
Step 2: Open the AC Control Panel
Tap on your air conditioner from the app’s home screen. This will open the control interface, where you can adjust temperature, mode, fan speed, and more.
Step 3: Access Advanced Settings
Look for a gear icon or “Settings” button, usually in the top-right corner. Tap it to open advanced options.
Step 4: Find the Filter or Maintenance Section
Scroll through the settings until you find “Filter,” “Maintenance,” or “Clean Filter Alert.” Tap to open.
Step 5: Disable the Clean Filter Alert
Toggle the switch to “Off.” You may receive a confirmation message asking if you’re sure—tap “Yes” or “Confirm.”
Note: Some models allow you to set a custom filter reminder interval (e.g., every 30 days). You can adjust this or disable it entirely.
Step 6: Save and Exit
The change takes effect immediately. You can now operate your AC without the Clean Filter alert interrupting.
Bonus Tip: Use the app to monitor filter usage over time. Even with alerts off, the app may still track how long it’s been since the last cleaning—helping you stay on top of maintenance.
How to Turn Off Clean Filter on Window or Portable LG Units
Window and portable LG air conditioners may not have full menu systems like split units, but many still include a Clean Filter function. Here’s how to manage it:
For Window Units with Digital Displays
– Press the Menu or Function button.
– Navigate to “Filter” or “Maintenance.”
– Select “Clean Filter Alert” and turn it off.
For Models with a Dedicated Filter Button

- Schedule annual professional maintenance: A technician can check refrigerant levels, electrical connections, and overall performance.
- Re-enable the Clean Filter alert when done: Once your task is complete, turn the feature back on to maintain system health.
Pro Tip: Set a calendar reminder to check your filter monthly. This habit prevents buildup and keeps your AC running efficiently year-round.
When Not to Turn Off the Clean Filter Alert
While it’s technically possible to disable the Clean Filter function, there are times when you should avoid doing so:
- If you haven’t cleaned the filter: Running the AC with a dirty filter can damage the motor and reduce cooling power.
- In high-pollen or dusty environments: Homes with pets, smokers, or near construction sites need frequent filter changes.
- If you have respiratory issues: Clean filters improve indoor air quality, which is vital for asthma or allergy sufferers.
- During peak summer or winter: The AC works harder in extreme temperatures—clean filters ensure maximum efficiency.
Use the “turn off” feature sparingly and only for short-term needs.
