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.
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

(see page 15). Press and hold for 3
seconds.
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 and Ecient Auto Mode (see

The plasma function uses PlasmaPro™
Technology to generate positive and
negative ions that bind with pollutants and
help reduce particulate matter, odorous
gases, aerosols, and volatile organic
compounds (VOCs).
The VeSync app allows you to access
additional smart air purifier functions,
including those listed below. As the app
develops, more features may become
available.
Remote Control
• Change any air purifier settings
through the app, even while Display
Lock is on.
Air Quality Updates
• View real-time PM2.5 updates in the
app.
• See your air quality history for the
previous week.
Auto Mode
• Access additional Auto Modes: Quiet
Auto Mode and Ecient Auto Mode.
• 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.
• Ecient 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.

ABOUT THE FILTER
The air purifier uses a 3-stage filtration
system to purify air.
A. Pre-Filter
• Captures large particles such as
dust, lint, fibers, hair, and pet fur.
• Maximizes the filter’s life by
protecting it.
B. Main filter
• 99.97% filtration eciency for
0.1-0.3μm airborne particulates,
including pollen, dust, and animal
dander allergens.
A
B
C
Note: This air purifier includes an optional Plasma Function, which is a 4th filtration stage that helps
neutralize some pollutants (see page 11).
C. Custom High-Eciency Activated
Carbon Filter
• Physically adsorbs smoke, odors, and
fumes.
Note: Tested by an independent lab.
14
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.
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 diusers near the air
purifier.
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 eective for larger rooms, but
air purification will take longer, with fewer
air changes per hour. For example, the air
purifier’s eective range is 1,008 ft² / 93.5 m²
based on 2 ACH, or purifying the air in the
room 2 times per hour.
This air purifier has a Clean Air Delivery Rate of
260 cubic feet per minute (CFM), or 442 m³/h.
Clean Air Delivery Rate (CADR) measures the
eciency 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.

VESYNC APP TROUBLESHOOTING
My smart air purifier isn’t connecting to the VeSync app.
• Make sure your phone has Bluetooth® turned on and is not currently connected to another
Bluetooth device.
• During the setup process, you must be on a secure 2.4GHz Wi-Fi® network. Confirm that the
network is working correctly.
• Make sure the Wi-Fi password you entered is correct.
• There should be no spaces at the beginning or end of the password.
• Test the password by connecting a dierent electronic device to the router.
• If you’re manually typing in the SSID and password, double check that both are entered
correctly.
• Try moving your air purifier closer to the router. Your phone should be as close as possible
to your air purifier.
• Your router may need to be at a higher location, away from obstructions.
• Make sure your air purifier and router are away from appliances (such as microwave ovens,
refrigerators, electronic devices, etc.) to avoid signal interference.
• If you’re using a VPN, make sure it’s turned o while setting up your air purifier.
• Disable portal authentication for your Wi-Fi network. If portal authentication is enabled, the
air purifier will not be able to access your Wi-Fi network, and setup will fail.
My air purifier is oine.
• Make sure the air purifier is plugged in and has power, then refresh the VeSync menu by
swiping down on the screen.
• Make sure your router is connected to the internet and your phone’s network connection is
working.
• Delete the oine air purifier from the VeSync app. Swipe left (iOS®) or press and hold
(Android™), then tap Delete. Reconfigure the air purifier with the VeSync app.
Note: Portal authentication means that you need to sign in to your Wi-Fi network through a
web page before you can use the Internet.
Note: Power outages, internet outages, or changing Wi-Fi routers may cause the air purifier
to go oine.
