Maintenance
Cleaning the outside of the air purifier
1. Switch off the device and pull the plug.
2. Use a soft and humid piece of cloth to clean the device from dust and dirt.
3. Make sure that no water gets into the device.
Cleaning of the Intelligent Particle Sensor™
Clean the air quality sensor every 6 to 8 weeks.
When the value of PM 2.5 is displayed incorrectly, a cotton swab can be used to clean
the sensor lens.
1. Remove the cover of sensor.
2. Clean the sensor lens with a cotton swab and water as indicated by the arrow.
Then dry the lens with a clean cotton swab.
3. Install the cover of sensor.
4. Do not wipe the sensor lens with alcohol or other organic solvent.
Attention! If the humidity in the room is very high, there is a risk of condensation on the air quality
sensor. This may cause the air quality indicator (Digital Display - Particle Measurement) to indicate
that the air quality is poor, while this should not be the case. In this case, we recommend that
you clean the air quality sensor or do not use the air purifier in automatic mode.
