SAFETY INFORMATION

To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines.

General Safety.

• Only use your air purifier as described in
this manual.
Do not use without removing the plastic wrap
from the filter. The air purifier will not filter air,
and may overheat, causing a fire hazard.
Do not use the air purifier outdoors.
• Keep the air purifier away from water, and wet
or damp areas. Never place in water or liquid.
Do not use in excessively humid areas.
• Keep the air purifier away from heat sources.
Do not use where combustible gases, vapors,
metallic dust, aerosol (spray) products, or
fumes from industrial oil are present.

on the center of the display.
1.

Tap
to change the air quality
information shown on the center of the
display.

2. Keep tapping
to cycle through air
quality readings for PM1.0, PM2.5, PM10,
and overall clean air percentage. For more

3. When you stop tapping
, the
current air quality reading will stay on the
display until you restart the air purifier.
If you restart the air purifier, the display
will again show the overall clean air
percentage.

Clean Air Percentage
Clean air percentage is an estimated
measurement of the amount of clean air in the
room, between 0% (bad) to 100% (very good).
This percentage is calculated by an algorithm,
based on:

The concentration of particles detected in the
air, including micro-particles.

The change in detected particles in the air
during purification.
Note: The percentage is approximate. The
sensor can only detect airborne particles, not
odors or gasses.

PM Values
“PM” stands for “Particulate Matter,” and usually
refers to airborne particles floating in your air,
including dust and most allergens. Many of
these particles are too small to be seen with
the naked eye, and without air purification,
they stay in the air much longer than heavier
or larger particles.
Your air purifier’s AirSight Plus 2.0 Laser
Dust Sensor detects the amount of airborne
particles that are in a given space (µg/m³).
Generally, the lower the number, the better
your air quality.

11

USING YOUR SMART AIR PURIFIER (CONT.)
When you press
to show PM
readings on the display, the number is the
estimated amount of airborne particles (µg)
that are detected per 1 cubic meter (m³) of air
volume.

3.

Note:

The PM value (1.0, 2.5, or 10) refers to
particulate matter (PM) less than or equal to
1, 2.5, or 10 microns (µm) in size (measured
by the diameter of the particle). For example,
PM2.5 refers to particulate matter that is 2.5
microns or smaller.

ABOUT THE FILTER (CONT.)

Clean Air Delivery Rate

Humidity

This air purifier has a Clean Air Delivery Rate of
360 cubic feet per minute (CFM), or 612 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.

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 558 ft² / 52 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 1,395 ft² / 130 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.

16

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.

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 different 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 off 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.
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.

My air purifier is offline.

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 offline 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: Power outages, internet outages, or changing Wi-Fi routers may cause the air purifier
to go offline.
