Levoit Core 400S Series User Manual

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 (g) that are
detected per 1 cubic metre (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 mould.
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:
• 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
filter (see page 14).
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 colour
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 Ecient Auto
Mode (see page 11).
