Sleep Mode
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.
Sleep Mode operates quietly by using a fan
speed lower than low speed.
1. Tap
to turn Sleep Mode on/off.
2. Sleep Mode will turn off the display after
3 seconds if no other buttons are tapped.
•
•
Auto Mode does not use the turbo fan
speed.
Note:
The VeSync app also supports
additional auto modes: Quiet Auto
Mode and Efficient Auto Mode (see
page 11).
•
•
When the display is turned off, tap any
button (except ) to turn the display
back on. If you don’t tap another
button, the display will turn off 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 15).
PM2.5 Display
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.
•
•
You cannot use the plasma function
during Sleep Mode.
The Sleep Mode button is also used
to reset the Check Filter Indicator
(see page 15). Press and hold for 3
seconds.
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.
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
speed.
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.

develops, more features may become
available.
Standby Mode
The air purifier is in Standby Mode when it is
turned off, but plugged in.
Note: Display Lock can be used while the
air purifier is in Standby Mode to keep
the air purifier from being turned back
on. The laser dust sensor will still detect
the surrounding air quality and give you

off, it will remember its previous fan speed,
Sleep Mode, Auto Mode, Display Lock,
Display Off, and Plasma settings.
•

previous week.
When you unplug the air purifier, it will only
remember its previous fan speed, Sleep
Mode, and Auto Mode.
Auto Mode
•
Access additional Auto Modes: Quiet
Auto Mode and Efficient Auto Mode.
Note: The air purifier will remember the last
timer setting chosen (1–12 hours), but it will not
automatically resume the timer. You will need
to restart the timer after the air purifier is turned
back on.
•
Quiet Auto Mode uses medium fan
speed instead of the high or turbo
fan speeds, even when the air quality
is poor, to avoid making too much
noise.
•
Efficient Auto Mode lets you choose
the size of the area you want to
purify. The air purifier will use the
highest fan speed (turbo) to clean the
air for a designated amount of time.
This time is based on ACH 1 and the
size of the room, meaning how long
it takes for the air purifier to clean
all the air in your room one time,
regardless of the air quality. After this,
the mode will adjust the fan speed
according to the actual detected air
quality in the room.
Plasma Function
The plasma function uses PlasmaPro™
technology to generate positive and negative
ions that bind with pollutants and neutralize
them by breaking down their molecular
structure.
This helps neutralize particulate matter,
odorous gases, aerosols, and volatile organic
compounds (VOCs).
Note: You cannot use the plasma function
during Sleep Mode.
Note: Efficient Auto Mode is useful for
purifying odors from the air. The air purifier’s
sensor can only detect particles in the
air, not smells. Efficient Auto Mode does
not rely on the sensor, but the room size
instead.

ABOUT THE FILTER (CONT.)
Clean Air Delivery Rate
Humidity
This air purifier has a Clean Air Delivery Rate of
260 cubic feet per minute (CFM), or 442 m³/h.
Moisture may damage the filter. This air
purifier should be used in an area with a
humidity level below 85% RH. If you use the
air purifier in excessively humid areas, the
surface of the filter may become moldy.
Clean Air Delivery Rate (CADR) measures the
efficiency of an air purifier by indicating the
volume of clean air that an air purifier produces
per minute. This is based on removal of dust,
pollen, and smoke, which are the 3 most
common indoor air pollutants. The higher the
CADR, the more particles the air purifier will
remove and the larger the area it can clean.
The rating is measured at the air purifier’s
highest speed.
Note: Water or moisture will allow mold to
grow. To solve a mold problem, get rid of
the source of the moisture and clean up
the mold.
Essential Oils
Do not add essential oils to the air purifier or
filter. The filter will become damaged by the
oil and will eventually release an unpleasant
smell. Do not use diffusers near the air
purifier.
Air Change Per Hour
The air change rate is how many times
all of the air in a room can be purified (or
“changed”) by the air purifier in 1 hour. Air
changes per hour (ACH) are calculated with
the recommended room size assuming 8 ft
/ 2.4 m ceilings. For smaller rooms, the air
change per hour will increase. This air purifier
can change air 5 times per hour at the max
speed in a single, closed room up to 403
ft² / 37 m². This is measured at ACH 5. The
air purifier is effective for larger rooms, but
air purification will take longer, with fewer
air changes per hour. For example, the air
purifier’s effective range is 990 ft² / 92 m²
based on 2 ACH, or purifying the air in the
room 2 times per hour.
Note: To effectively clean air, keep windows
and doors closed while the air purifier is on.
