• The concentration of PM/UFP may differ
depending on the environmental factors
to which the device is exposed, e.g., a
construction site, road side, fabric sofa,
vacuum cleaner, bedding, or clothes.
• The air purification level may increase in a
location with a fabric carpet, a veterinary
clinic or clothing store exposed to lots of hair,
a highly humid location, or a location where
there is smoke or many insects.

• The air purification level can be affected
by odorous household items, such as air
fresheners, deodorants, or detergents.
• The device may continue to display a high air
purification level reading in an environment
where there is inflow of dust or outdoor air
(e.g., proximity to an HVAC/ventilation system
or draughty windows in the building).
• The PM/UFP levels are measured in real time
and may not match the values forecast by the
Ministry of Environment.
• The PM/UFP readings may increase
temporarily if the device is affected by
electromagnetic waves or electrical noise.
• If two devices are installed close to each
other, the devices may display different air
purification level readings depending on the
distance from the source of dust.
CAUTION
• Do not touch the purification filter during
the air purifying operation. This may result in
electric shock.
