Cleaning the filter housing
To maintain optimal ventilation and
purification efficiency, remove any dust
on the ventilation holes and housing
walls using a vacuum cleaner or soft
cloth.
Note: Do not spray liquid onto the purifier's casing,
or wipe it using a wet cloth. This could lead to
drops of water leaking into the base of the device.
Cleaning the laser particle
sensor
The catch of the particle sensor cover
flap is on the rear cover just above the
filter housing. Press the catch upwards
and open the sensor flap (as Figure a).
Use an air blow gun or hair dryer to clean
the filter on the cover and the sensor (as
in Figure b).
Note: Do NOT clean with hot air.
