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 risk index among
PM2�5, IAI and Gas readings�
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�
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�
