The air quality light is red or purple too often and the PM 2.5 values shown in the app are very high all the time

Issue

• The app shows high values too often
• The ring on the air purifier lights up red or purple
• My air purifier suddenly has the highest fan speed
• The air quality light is red or purple too often

Applies to

• AEG AX9 series air purifiers
• AEG AX5/AX7 series air purifiers

Resolution

Dust accumulated in the air quality sensor(s) can result in incorrect readings and affect the product 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 if the product is used daily. Never use abrasive, harsh cleaning tools - this can damage the sensor.

If the problem persists, even after multiple cleaning attempts, please contact an AEG / Electrolux service station for further guidance.

AX9 series sensor location

Cause

• Dust can enter the sensor and cause the values for particles to be displayed incorrectly in the app and the air quality light to glow red on the air purifier
