The air purifier draws in room air through the air inlet, circulates
it through a Pre-Filter, a Deodorizing Filter and a HEPA Filter
inside the product, and then discharges it through the air outlet.
The HEPA Filter can remove 99.97% of dust particles as small
as 0.3 microns that pass through the filter and also helps absorb
odors.
The Deodorizing Filter gradually absorbs odors as they pass
through the filter.
Some odors absorbed by the filters will break down over time,
causing additional odors. Depending on usage conditions, and
especially if the product is used in environments significantly
more severe than a normal household, these odors may become
noticeable sooner than expected. If these odors persist, replace
the filters.
When minerals in tap water adhere to the filters and become hard and white, they absorb odors in the room
that can cause the emission of an unpleasant odor when the Humidifying Filter is dry. (Varies depending on
water quality and other environmental factors.)
If this occurs, perform the Humidifying Filter maintenance. (Page 20)
NOTE
• The air purifier is designed to remove air-suspended dust and the odors.
The air purifier is not designed to remove harmful gases such as carbon monoxide contained in
cigarette smoke.
The air purifier may not completely remove an odor if the source of the odor is still present.

FEATURES
A unique Combination of Air Treatment Technologies
Triple Filtration System + Humidification + Plasmacluster
Plasmacluster
High Density Plasmacluster 25000
The higher the PCI density is, the more effective PCI has.
By emitting a balance of positive and negative ions, Plasmacluster air treatment is a natural
process.
Triple Filtration System + Humidification
TRAPS DUST
Pre-filter traps dust larger than approx 240 micron particles.
DECREASES ODORS
Deodorizing filter absorbs many common household odors.
REDUCES TINY DUST, POLLEN & MOLD
HEPA filter traps 99.97% of particles as small as 0.3 microns.
HUMIDIFIES
Controls humidity by sensing temperature and humidity automatically.
Unique Airflow
Powerful air suction and unique airflow quickly and efficiently collect dust and other particles.
Faster airflow at a 20º angle causes dust to
be collected at lower levels in the room for
more effective cleaning.
Plasmacluster can remove static electricity
and can thus prevent dust from attaching to
walls and other surfaces.
Wi-Fi Function
• Confirms that the air quality of the room has become clean visually.
• Controls the product through smart devices such as a remote control.
• Proposes optimal timing for filter exchange.
