Why is there a sudden rise in the PM2.5 value displayed on the Mijia Smart Air Purifier Max?

Question

Accepted Answer

If there is a sudden increase in the PM2.5 value on the Mijia Smart Air Purifier Max, please refer to the following troubleshooting steps:
1. Check for indoor sources of particles such as cooking fumes, oil smoke, cigarette smoke, or operating a humidifier, as these can temporarily raise the PM2.5 reading.
2. Ensure that windows or doors are closed if outdoor air pollution is high, which can affect indoor PM2.5 levels.
3. Confirm that the purifier is placed in an appropriate location with unobstructed airflow and away from direct smoke or heavy fumes.
4. If PM2.5 readings fluctuate frequently and cannot be explained by indoor or outdoor factors, restart the air purifier or move it to another location for testing.
5. If the issue persists despite following these steps, please contact the after-sales service center for further assistance.
