PM 2,5 sensor and LED ring
The current air quality is continuously determined
by Airfresh Clean 400 in the form of the PM 2.5
value. The PM 2.5 value is defined as dust at
which 50 % of the particles are < 2.5μ and rep
resents the fine dust load per m³.
The illuminated LED ring on the upper side
indicates the current level of fine dust pollution
caused by different colours:
RED = high load (>50 µg/m³)
PINK = medium load (20 50 µg/m³)
LILA = low load (10 20 µg/m³)
BLUE = no load (0 10 µg/m³)
Please remove the protective flap in front of the PM2.5 sensor
(C) only in an emergency. Please do not allow any objects or
other foreign bodies to come into contact with the sensor.
