ABOUT THE FILTER (CONT.)
Clean Air Delivery Rate
This air purifier has a Clean Air Delivery Rate of
442 m³/h or 260 cubic feet per minute (CFM).
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
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 5,
which means it can change air 5 times per
hour at the max speed in a single, closed
room up to 37 m² / 403 ft². 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.
Humidity
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.
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
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.
