ABOUT THE FILTER (CONT.)
Clean Air Delivery Rate
This air purifier has a Clean Air Delivery
Rate of 221 m³/h or 130 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 are calculated on
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 3.3, which means it can change
air 3.3 times at the max speed in a
single, closed room up to 28 m² / 300 ft²
in size. 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 filters. 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 will
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, only remove
mould spores and reduce odours.
Essential Oils
Do not add essential oils to the air purifier
or air filter. The filter will become damaged
by the oil and will eventually release an
unpleasant smell. Do not use oil diffusers
near the air purifier.
