Auto Mode uses AirSight Plus™, a smart
laser dust sensor inside the air purifier, to
adjust the fan speed automatically based
on air quality. For example, if the air quality
is bad, the fan will automatically be set to
high speed.
The PM2.5 value on the display shows the
amount of airborne particles (g) that are
detected per 1 cubic meter (m) of air volume.
PM2.5 refers to particulate matter (PM) that
is less than or equal to 2.5 microns (m) in
diameter. These particles, also known as
“fine particles”, are so small that they can only
be detected with an electron microscope,
and they stay in the air longer than heavier
particles such as dust and mold.
Your air purifier’s AirSight Plus Laser Dust
Sensor detects the amount of PM2.5 particles
that are in a given space (g/m). Generally, the
lower the number, the better your air quality.
A number above 115 indicates that there is an
unhealthy amount of fine particles in the air.
Note:
• The air purifier will take 5 seconds
to detect the air quality each time
it is turned on. During this time, the
air quality indicator rings will be
blue. After 5 seconds, the air quality
indicator rings will change color
based on the detected air quality.
• Auto Mode does not use the turbo
fan speed.
• The VeSync app also supports
additional auto modes: Quiet Auto
Mode, Ecient Auto Mode, and ECO
Auto Mode (see page 13).
