The air quality light automatically
goes on when the air purier is
switched on, and lights up all colors
in sequence. After approximately
30 seconds, the air quality sensors
select the color that corresponds
to the surrounding air quality of
airborne particles.
The color of the air quality light is
determined by the highest level
among PM2.5, Gas and IAI 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.

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.

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 ne 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.
