Method of Operation
Connect the power: Connecting the power, the unit will start to work when it is plugged in. The initial mode will be
medium-fan-mode (without ionizer function).
Anschluss des Netzkabels: Once the power cord is connected , the unit starts to work in medium-fan-mode, the
ionizer is turned off, the LEDs light up briefly and the particle sensor is activated.
On / Off-button: Pressing the power button, the unit will be switched off/on.
If the unit is switched on again, the last selected mode will be activated and could be changed then.
Fan Speed-button: Press the button for selection of fan speed. The LED screen will indicate one
sign for low speed, two for medium and three for high and a sign for the PM 2,5 -Sensor-controlled
automatic operation.
Press the button to use the timer function. According your selection, the air cleaner will run for 4, 8
or 12 hours. The Timer-Function can be combined with all other functions.
If the Sleep-Mode is selected, the air cleaner works very quiet with reduced air quantity. All LEDs will

Air quality indication and AUTO-Mode with intelligent PM 2.5 - Sensor Control
1. The air purifier measures the air quality by using an intelligent dust
sensor and displays it in color:
blue = clean air
yellow = deterioration of air quality
red = high air pollution
The as fine dust (PM2.5) called dust fraction contains 50% of the particles having a diameter of 2.5 microns, a higher
proportion of smaller particles and a lower proportion of larger particles. Particles of this size can go up in the air sacs.
They are at most as large as bacteria and therefore cannot be seen with the naked eye.
The air quality assessment already takes into account the guideline by the WHO (World Health Organization) valid
from 2020. That means, that the PM 2.5 value will be below 20 ug / m3 for the indication of clean air (blue)
For an optimal and sustainable air cleaning result we recommend the use as described under item 1 and 6.
