If the laser particle sensor fan sometimes stops running on the Mijia Smart Air Purifier 6, please refer to the following information:
When the Mijia Smart Air Purifier 6 is powered on and the screen is on, the sensor works continuously, displaying real-time values;
When the display is off, to reduce sensor usage and extend its lifespan, the sensor activates once every 2 minutes and runs for 12–15 seconds;
When the Xiaomi Home App is open, the sensor also operates continuously. If the App is closed and the screen is off for 5 minutes, the sensor will work intermittently.
Note:
The air purifier will still provide accurate air quality values even when the sensor runs intermittently.
