PM2.5 Display  
The PM2.5 value on the display shows the  
amount of airborne particles (µg) that are  
detected per 1 cubic metre (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 mould.  
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.

ABOUT THE FILTER  
The air purifier uses a 3-stage filtration  
system to purify air.  
A
B
C
A. Pre-Filter  
Customised using the ARC formula  
to be especially effective for cooking  
smells and pet odours in a multi-pet  
household.  
Captures large particles such as dust,  
lint, fibres, hair, and pet fur.  
Maximises the filter’s life by  
protecting it.  
Filters compounds such as  
formaldehyde, benzene, ammonia,  
hydrogen sulphide, and volatile  
organic compounds (VOCs).  
B. H13 True HEPA Filter  
Captures at least 99.97% of airborne  
particles 0.3 microns (µm) in size  
*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.  
Traps small particles such as mould  
spores, fine dust, smoke particles,  
bacteria and viruses*, and allergens  
such as pollen, dust mites, and pet  
dander.  
C. Custom High-Efficiency Activated  
Carbon Filter  
Physically adsorbs smoke, odours,  
and fumes.

ABOUT THE FILTER (CONT.)  
Clean Air Delivery Rate  
Humidity  
This air purifier has a Clean Air Delivery Rate  
of 400 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 mouldy.  
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 mould to  
grow. To solve a mould problem, get rid of  
the source of the moisture and clean up the  
mould. Air purifiers cannot solve an existing  
mould problem, and can only remove  
airborne mould spores and reduce odours.  
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 83 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.
