- The PM sensor value is very high and my air purifier increases the air speed all of a sudden
- AEG AX9 series air purifiers
- Dust accumulated in the Air Quality sensor can result in incorrect sensor readings and affect performance. Use a vacuum cleaner with a soft brush to remove any dust that might accumulate in this area. Vacuum (at least) once a month. Never use abrasive, harsh cleaning tool this can damage the sensor.
