Potential Cause: After a long periods of operation, the sensor inlet may get dusty thus showing incorrect levels that do not improve.
Troubleshooting Steps:
- Unplug the air purifier and wait for approximately 30 seconds.
- Check for any objects or dust around the air quality sensors at the front of the air purifier. Gently wipe away the dust on the sensor with a soft cloth.
- Reconnect the power cable to the air purifier.
- Press the power button to restart the air purifier.
- If, despite using the air purifier and proper ventilation, the air quality still does not improve, please contact customer support for further assistance.
