Common Causes of Levoit Air Purifier Filter Light
The filter light on your Levoit air purifier illuminates to indicate it’s time to replace the filter. However, several factors can cause it to stay on even after a new filter has been installed:
- Incorrect Filter Installation: The filter may not be seated properly, preventing the sensor from recognizing its presence.
- Sensor Malfunction: The filter replacement sensor itself could be faulty.
- Reset Method Not Applied Correctly: Different Levoit models require different reset procedures.
- Power Cycle Issue: A simple power interruption can sometimes resolve the issue.
- Filter Life Timer Not Reset: The internal timer hasn’t been reset to recognize the new filter.
How to Turn Off the Filter Light: Multiple Methods
Here are several methods to reset the filter light on your Levoit air purifier, ranging from simple to more advanced:
Method 1: The Standard Reset Button (Most Common)
This method applies to many Levoit models, including the Core 300S, Core 400S, and Core 600S.
Diagnosing the Issue
Confirm the filter is correctly installed. Ensure it’s fully seated and the cover is securely closed.
Fix Steps
- Locate the Reset Button: The reset button is typically located on the control panel, often a small recessed button labeled “Reset” or indicated by a symbol.
- Press and Hold: Press and hold the reset button for 5-10 seconds. You may or may not hear a beep or see a visual confirmation.
- Test the Reset: Turn the air purifier on. The filter light should be off. If it remains on, repeat the process, holding the button for a slightly longer duration.
Testing
Observe the air purifier for a few minutes to ensure the light stays off.
Method 2: Long Press Power Button Reset
This method is used for some Levoit models, particularly older ones.
Diagnosing the Issue
Verify the filter is properly installed.
Fix Steps
- Unplug the Purifier: Disconnect the air purifier from the power outlet.
- Press and Hold Power Button: Press and hold the power button for 15-30 seconds.
- Plug Back In: Reconnect the air purifier to the power outlet.
- Turn On: Power on the air purifier. The filter light should be reset.

Monitor the purifier to confirm the filter light remains off.
Method 3: Filter Reset Combination (For Specific Models)
Some models require a specific combination of button presses.
Diagnosing the Issue
Check the filter installation.
Fix Steps
- Identify Your Model: Consult your Levoit air purifier’s user manual for the exact reset combination for your model.
- Follow Instructions: Most combinations involve holding two buttons simultaneously for a set duration (e.g., power button and speed button).
- Test: Power on the purifier and verify the light is off.
Testing
Confirm the reset was successful by observing the purifier’s operation.
Method 4: Power Cycle and Reset
This method combines a power interruption with a reset attempt.
Diagnosing the Issue
Ensure the filter is installed correctly.
Fix Steps
- Unplug: Disconnect the air purifier from the power outlet.
- Wait: Let the purifier sit unplugged for at least 60 seconds.
- Reset Button: Press and hold the reset button (as described in Method 1) for 5-10 seconds.
- Plug In and Power On: Reconnect the purifier and turn it on.
Testing
Observe the purifier for several minutes to see if the filter light remains off.
Prevention Tips and Maintenance Advice
- Genuine Levoit Filters: Always use genuine Levoit replacement filters. Non-genuine filters can cause sensor issues and reduce purifier performance.
- Regular Filter Replacement: Replace the filter according to the manufacturer’s recommendations (typically every 6-8 months, depending on usage).
- Proper Installation: Carefully follow the instructions in your user manual when installing a new filter.
- Clean the Sensors: Gently clean the filter replacement sensor area with a soft, dry cloth periodically.
- Avoid Excessive Dust: While an air purifier is designed to handle dust, excessive dust buildup around the sensor can interfere with its operation.
Pro Tips
- User Manual is Key: Always refer to your Levoit air purifier’s user manual for specific instructions related to your model.
- Reset After Filter Change: Reset the filter light immediately after installing a new filter.
- Avoid Water: Do not use water or cleaning solutions directly on the sensor area.
- Check for Software Updates: Some Levoit models can be updated with firmware that may address sensor issues. Check the Levoit app or website for updates.
- Sensor Sensitivity: Some sensors are more sensitive than others. If the light comes back on quickly, it may indicate a particularly dusty environment.
- Filter Light Doesn’t Indicate Air Quality: The filter light is a timer-based indicator, not a measure of actual air quality.
Professional Help
- When to Seek Professional Help: If you’ve tried all the reset methods and the filter light remains on, or if you suspect a faulty sensor, contact Levoit customer support.
- What to Look For in Support: Look for responsive and knowledgeable support representatives who can guide you through troubleshooting steps or arrange a repair/replacement.
- Warranty Considerations: Check your air purifier’s warranty to see if sensor issues are covered.
