Why does my air-Q show high particulate matter values?

The fine dust sensors are very sensitive to even the smallest changes in particles and fine dust changes. 

The causes of high particulate matter levels are manifold. Often, fine dust is generated outdoors, e.g. by pollen, traffic, industry or agriculture, or even Sahara dust, which is carried to Germany by the wind. Indoors, frying and baking or fireplaces and candles are possible sources of particulate matter.

Very high humidity can falsify the displayed measured values for fine dust. The reason for this is that the smallest water droplets are identified as fine dust by the fine dust sensor. However, this can only happen at very high relative humidities from 80-90% – i.e. close to the condensation point (dew point). If the air-Q is set up in the bathroom, this effect can be observed well.

A permanently high fine dust reading can also be due to a dirty fine dust sensor.
