Air exchange per hour
The air exchange rate indicates how often the air
purifier can clean (or “exchange”) the air in a room
within an hour. The air exchange rate is calculated
for the recommended room size with a ceiling
height of 2.4 m / 8 feet. The air exchange rate per
hour increases in smaller rooms. The CLR 250 has
an air exchange rate of 3.5 per hour i.e., at max-
imum speed, it can exchange the air five times
every hour. This air purifier is intended for use in a
single enclosed space of up to 30 m
2
.
To purify the air effectively, keep windows and
doors closed when the air purifier is in opera-
tion.
Air humidity
Humidity can damage the filter. This air purifier
must only be used in an environment with a
humidity below 85% RH. If you use the air purifier
in an exceedingly high humidity environment, the
surface of the filter will become mouldy.
Mould can form due to water or moisture. Air
purifiers cannot eliminate an existing mould
problem, only absorb mould spores and reduce
odours.
Essential oils
Do
not
put essential oils in the air purifier or on the
filter. The oil damages the filter and will give off an
unpleasant odour after a while. Do
not
use dif-
fusers in the vicinity of the air purifier.
