Use and Care Manual

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).
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.

USING YOUR PURIFIER (CONT.)
The air purifier is in Standby Mode when it is 
turned o, 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 
updates in the VeSync app. 
Note: Ecient Auto Mode is useful for 
purifying odors from the air. The air purifier’s 
sensor can only detect particles in the 
air, not smells. Ecient Auto Mode does 
not rely on the sensor, but the room size 
instead.
When the air purifier is plugged in and turned 
o, it will remember its previous fan speed, 
Sleep Mode, Auto Mode, Display Lock, 
Display O, and Plasma settings.
When you unplug the air purifier, it will only 
remember its previous fan speed, Sleep 
Mode, and 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. 
Note: You cannot use the plasma function 
during Sleep Mode.
