Odors(odors accompanied by daily life) that cannot be removed

by the silver ion filter may be absorbed by the dehumidifier
rotor inside the unit.
If the room contains any of the following items, the corresponding
②
odor will be absorbed by the dehumidifier rotor inside the dehumidifier.
Also, that absorbed odor will be heated by the heater, which
may result in a burning like smell or other abnormal odor.

new furniture, etc.) Explain to the customer that the unit is normal.
OK
In the zeolite system, the zeolite absorbs every odor with moisture
YES
in the room. Usual absorbed odor is resolved by the heat
emitted by the heater when heating up moisture to change it
to dew, and it is scattered.
However, when the high-boiling organic principle, which is included
in building materials, paint, wax, etc, is absorbed, it cannot be
resolved by heat emitted by the heater.
Unresolved odor is accumulated little by little, which may result
OK
in a worse smell and/or burning like smell.
Moreover, single component of odor is not recognized by itself,
when some of them are mixed, however, several odors ( bad
smells ) may be generated.
NG
Replace the zeolite.
