Auto Mode
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

PM2.5 Display
The PM2.5 value on the display shows the
amount of airborne particles (µg) that are
detected per 1 cubic metre (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 mould.
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.
