Question

What does the device show me? What is my air quality?


Answer

The currently measured air quality is shown on the display in PM2.5 and by the illuminated ring around the control panel.


Number: The number on the display shows the level of particulate pollution in the air. This is displayed in micrograms per cubic metre (µg/m³). The lower the number, the lower the particle load and the better the air quality. 


The device measures fine dust particles with a size of 2.5 micrometres (=0.0025mm) and smaller. These particles are generally referred to as PM2.5. 


If the reading is between 0-100 micrograms, the air quality is still OK. The air quality drops at higher levels.


Colour: The device also displays the air quality as a colour.


Blue
means that the air quality is good and the appliance is running at a low fan speed.
Yellow
means that the air quality is moderate and the appliance is running at a medium fan speed.
Red
means that the air quality is very dirty and the appliance is running at turbo fan speed.
