4 Using the air purifier

Understanding the air quality light

The air quality light automatically goes on when the
air purifier is switched on, and lights up all colors
in sequence. After approximately 30 seconds, the
particle sensor selects the color that corresponds to
the surrounding air quality of airborne particles.
The color of the air quality light is determined
by the highest index among PM2.5, IAI and Gas
readings.
IAI
The professional-grade AeraSense sensor detects the level
of indoor air allergen and with numerical feedback from 1
to 12 the potential risk level of indoor air allergens can be
displayed. 1 indicates best air quality.
PM2.5
AeraSense sensing technology accurately detects
and quickly responds to even the slightest particle
change in the air. It provides you with reassurance
with real-time PM2.5 feedback.
Most of the indoor air pollutants fall under PM2.5 –
which refers to airborne particle pollutants smaller
than 2.5 micrometers. Common indoor sources of
fine particles are tobacco smoke, cooking, burning
candles. Some airborne bacteria and the smallest
mold spores, pet allergen and dust mite allergen
particles also fall under PM2.5.
GAS
With an advanced gas sensor, a display ranging from L1 to
L4 shows the level change of potential harmful gases (incl.
VOC, odor, etc.) detected. L1 indicates best air quality.
