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

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.
The humidity reading on the unit
may differ from a hygrometer in
the same room
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.

Things to be aware of
Values obtained when the unit was operated on “high” in a humidity of 60%.
¡The dehumidification values shown on the graph were measured at constant
temperature and humidity and do not reflect actual usage conditions.
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.
1The unit draws air from the room, cools it with its
cooling coil, causing the moisture to transform
into water droplets.
2The water droplets fall into the water tank.
3The 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.
