Dirty Air
Clean Air
Pet odor and the smell of
cigarette smoke are
removed by decomposition
by weak ozone O3.
Clean Air
Activated charcoal
bacteria eliminating &
deodorizing filter
Polyphenol filter
(Grapefruit seed extract)
Earth conductor
Plasma filter generates
ions and ozone.
Electric pole
Electrostatic
filter
Dirty Air
Negatively-charged dust, etc. are attracted
to the earth section and are collected by a
bacteria eliminating & deodorizing filter.
Plasma air filter mechanism
Washable filter
Restored to the same performance
as when new each time it is washed.
Plasma unit
Mounts a plasma air cleaning unit.Minute dust
particles are collected by an electrostatic filter and odor
is suppressed by decomposition of foul odors by very
weak ions. Since a filter with a lower ventilation
resistance than in the past is used, high dust collection
design simultaneously cleans in the air in the room.

Easy maintenance
Easy maintenance and always clean. Troublesome maintenance has been made easy.
Since the front panel is easy to remove, maintenance is also easy.
Inner drying operation and plasma effect
This model is equipped with an inner drying function. After the power is turned off, the dry operation starts
inside the air conditioner. The plasma air cleaning unit eliminates bacteria, deodorizes, and keeps
the interior of the air conditioner clean by generating ozone and ions.

of the air conditioner clean
at all times. That’s why air
from the air conditioner is
always clean and high
efficiency is realized.
