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 10).  
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 13).  
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.  
Auto Mode  
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 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.

USING YOUR PURIFIER (CONT.)  
Auto Mode  
Standby Mode  
Access additional Auto Modes: Quiet  
Auto Mode and Efficient Auto Mode.  
The air purifier is in Standby Mode when it is  
turned off, but plugged in.  
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.  
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 updates in the VeSync app.  
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.  
Memory Function  
When the air purifier is plugged in and  
turned off, it will remember its previous fan  
speed, Sleep Mode, Auto Mode, Display  
Lock, and Display Off settings.  
When the air purifier is unplugged and  
turned off, it will only remember its previous  
fan speed, Sleep Mode, and Auto 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.  
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.

ABOUT THE FILTER  
The air purifier uses a 3-stage filtration  
system to purify air.  
A
B
C
A. Pre-Filter  
Customized using the Levoit’s  
exclusive ARC Formula™ to be  
especially effective for cooking  
smells and pet odors in a multi-pet  
household.  
Captures large particles such as dust,  
lint, fibers, hair, and pet fur.  
Maximizes the filter’s life by  
protecting it.  
The ARC Formula extends the life of  
the filter by chemically decomposing  
molecules trapped within the  
Activated Carbon Filter, which  
prevents oversaturation and second-  
hand pollution.  
B. H13 True HEPA Filter  
Captures at least 99.97% of airborne  
particles 0.3 microns (µm) in size.  
Traps small particles such as mold  
spores, fine dust, smoke particles,  
bacteria and viruses*, and allergens  
such as pollen, dust mites, and pet  
dander.  
Filters compounds such as  
formaldehyde, benzene, ammonia,  
hydrogen sulfide, and volatile  
organic compounds (VOCs).  
C. Custom High-Efficiency Activated  
Carbon Filter  
*The H13 True HEPA Filter can remove  
most viruses and bacteria from the air,  
but cannot fully remove them from your  
environment. Air purifiers cannot prevent  
an infected person from spreading an  
infection, and cannot remove bacteria and  
viruses from surfaces. Please use this air  
purifier together with other precautions.  
Physically adsorbs smoke, odors,  
and fumes.

ABOUT THE FILTER (CONT.)  
Clean Air Delivery Rate  
Humidity  
This air purifier has a Clean Air Delivery Rate  
of 442 m³/h, or 235 cubic feet per minute  
(CFM).  
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,  
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. Air purifiers cannot solve an existing  
mold problem, and can only remove  
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.  
airborne mold spores and reduce odors.  
Essential Oils  
Air Change Per Hour  
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.  
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  
2.4 m / 8 ft ceilings. For smaller rooms, the  
air change per hour will increase. This air  
purifier has an air change per hour of 2,  
which means it can change air 2 times per  
hour at the max speed in a single, closed  
room up to 92 m². The air purifier is effective  
for larger rooms, but air purification will take  
longer, with fewer air changes per hour.  
Note: To effectively clean air, keep windows  
and doors closed while the air purifier is on.

Cleaning the Filter  
The outer pre-filter should be cleaned every  
2–4 weeks to increase efficiency and extend  
the life of your filter. Clean the pre-filter using  
a soft brush or vacuum hose to remove hair,  
dust, and large particles. [Figure 3.1] Do not  
clean the filter with water or other liquids.  
The VeSync app uses a scientific algorithm to  
determine your filter life based on air quality,  
amount of use, and other factors. The filter life  
percentage is based on 12 hours of daily use.

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.  
If your problem is not listed, please contact Customer Support (see page 19).
