ABOUT THE FILTER (CONT.)
Clean Air Delivery Rate
This air purifier has a Clean Air Delivery Rate of
416 m³/h, or 245 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 can change air 5 times
per hour at the max speed in a single, closed
room up to 35 m² / 380 ft². This is measured
at ACH 5. The air purifier is effective for larger
rooms, but air purification will take longer, with
fewer air changes per hour. For example, the air
purifier's effective range is 88 m² / 950 ft² based
on 2 ACH, or purifying the air in the room 2 times
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 85% RH or below. 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.
