Sleep Mode operates quietly by using a fan
speed lower than low speed.
1. Tap to turn Sleep Mode on/o.
2. Sleep Mode will turn o the display after
3 seconds if no other buttons are tapped.
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 (µg) that are
detected per 1 cubic meter (m³) of air volume.
PM2.5 refers to particulate matter (PM) that
is less than or equal to 2.5 microns (µm) 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 (µg/m³). 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:
• When the display is turned o, tap any
button (except ) to turn the display
back on. If you don’t tap another
button, the display will turn o again
after 3 seconds.
• The Check Filter Indicator will still turn
on and stay on if it’s time to check your
lter (see page 14).
Note:
• The air purier 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 and Ecient Auto Mode (see
page 11).
