No bar (PM value 0-30) = Very good air quality > Air circulation goes out
3 bars (PM value 30-75) = Light air pollution > Air circulation jumps to level 1 (weak)
6 bars (PM value 75-150) = medium air quality > Air circulation jumps to level 2 (medium)
9 bars (PM value above 150) = Poor air quality> air circulation jumps to level 3 (strong)
In addition to the air quality display shown above, a PM value is also shown in the display. You can read at the top
which air quality category the respective PM value falls into.
Note: The air sensor is located at the front left of the unit and reacts mainly to odours and slightly to particles in the
air and thus always gives only a tendency of the air quality. Since it is a tendency (similar to a weather station), this
function cannot provide a 100% reliable statement about pollutants in the room air or about the entire area of a
room.
From a humidity of approx. 80% r.l. upwards, the air sensor probe may malfunction. In this case, please disable the
air sensor function (Auto).
Furthermore, stronger operating fluctuations may occur from time to time because the air sensor probe is exposed
to the draught.
Reset of the PM value / air sensor:
After prolonged use of the air sensor, traces of particles will stick to the inductive head of the sensor, which may
cause the numerical PM display to be abnormal. Only perform a reset if such an abnormal display is likely to occur!
If you find that the numerical PM reading deviates greatly from the normal range, we recommend that you record it
in the following steps based on the numerical PM reading of the weather forecast in your city.
1. First blow hard into the "compartment" of the air sensor (front left of the unit). Then open a window for 5
minutes and place the air purifier near the window (the air sensor records the current ambient data again).
2. Then press and hold the Settings icon until you hear a click. Now you are automatically in PM correction mode.
3. Each time you now press the "Settings" key, the PM number of the unit increases by 2ug/m³. Each time you
press the "Auto" key, you decrease the numerical PM value by 2ug/m³.
4. If you have adjusted the numerical PM values in the display to the numerical PM values of the weather forecast
of your city (check on the Internet), please wait 5 seconds and the value will be overwritten and stored.
