The washable photocatalytic filter has a two-layer
construction consisting of a white particle filter and a blue
air-freshener filter.
The fine particle filter removes pollen* and dust particles.
The special air-freshening agent contained in the fibres of
the air-freshener filter absorbs odorants such as ammonia.
The odor is broken down by photocatalysis renewing the
air-freshening properties.
As the filter’s particle and air-freshening properties are
renewed by simply soaking and leaving it to dry in the
sun, the air purifier can be used continuously over a long
time.
Cigarette smoke and toxins found in smoke, such as
carbon monoxide, cannot be removed with this filter.
* Diameter of pollen: approx. 10-100µm

e_mj_e20txh(01_19)_e33.qx 10/27/2003 5:17 PM Page 10
Things to be aware of
Room temperature may rise 2-4°C during operation
The dehumidifier does not have a cooler function. Due to heat produced during operation, the room temperature
may rise 2-4°C. As a result, the unit may blow warm air, but this is not due to a malfunction.
How does the dehumidifier work?
If you pour cold water into a cup, the air around it
becomes cold, causing water droplets to form on
the surface of the cup.
The dehumidifier takes advantage of this
phenomenon to remove moisture from the air.
Dried (warm) air
Cooling coil
1 The unit draws air from the room, cools it with its
Moist air
cooling coil, causing the moisture to transform
into water droplets.
2 The water droplets fall into the water tank.
Compressor
3 The dehumidified air is reheated by the
heating coil, and then discharged.
The humidity of the room is thus reduced by
repeating steps 1, 2, and 3.
The humidity reading on the unit
may differ from a hygrometer in
the same room
Re-heating coil
Water tank
<Cause>
● Inconsistencies
in temperature
and humidity
● Difference in
location
● Difference in
hygrometer
precision
Even in the same room, temperature and humidity
levels may differ from place to place. If the hygrometer
and the unit are in different parts of the room, the
humidity levels are prone to differ.
Moreover, humidity levels differ between places that
have good and no airflow.
Use the reading on the unit as an estimate.
Low temperature/humidity decreases dehumidifying effects
In winter, the temperature is low and the air is dry, therefore making dehumidifying impossible.
* If temperatures are low, but humidity is high due to snow or rain, operating the unit in LOW TEMP mode will
yield better results than LOW mode. 11

Information
∞ If the room temperature falls below 15°C,
defrosting mode is activated once every 40
minutes (for about 5 minutes) causing water
to drain to the tank.
9
12
∞ The unit can operate in a room temperature
range of 1-35°C.
However, if the room temperature exceeds
35°C, the unit may operate in blower mode or
increase the airflow. This is because the
temperature within the unit rises causing the
protection mechanism to operate. In order to
lower the temperature within the unit, when
using the louvre, point UP.
• If the temperature is below 1°C, the
extracted water is close to freezing disabling
the dehumidifier, and only the blower is
operational.
Minus ions
Minus ions are produced when the air flow
(dehumidifier/air purifier) is on. This function
cannot be deactivated.
What are minus ions?
Minus ions are particles in the air that possess a
negative charge. When there are a lot of minus
ions in the air, it is similar to the environment
encountered in a forest and is said to provide
relaxation.
