AIR PURIFICATION PROCESS
■ Pre-lter
The pre-lter made of microber uses a mesh trap to catch large particles such as pet fur and human hair.
■ Fine dust removal lter
Eectively captures and reduces small particles such as ne dust and ultrane dust.
■ HEPA lter
The high-performance synthetic HEPA lter is excellent at removing cigarette smoke and ne dust.
■ RBD Plasma lter
Emits radicals into the air sucked into the air purier to reduce pollutants, send it out to clean air and
activate the photocatalyst lter with plasma light for reducing odorous substances.
■ Photocatalyst lter
The photocatalyst lter is applied with inorganic adsorbent that reduces odor and harmful gas
(formaldehyde).
■ Activated carbon deodorization lter
Eectively reduces odor and harmful gas from the surface of activated carbon with micro-pore over
the surface of activated carbon and chemical reaction of specic functional group.

(basic setting) 0 ~ 15 16 ~ 35 36 ~ 75 76 ~
Gas pollution
level Level 1 Level 2 Level 3 Level 4
▶Pollution level color indicator shows the higher level of ne dust pollution level and gas pollution level.
ex) When ne dust pollution level is good and gas pollution level is normal, air pollution level is indicated as normal.
▶For gas, PM2.5 concentration guide and color display criteria, the company's algorithm is applied. The normal is set as
default for the product pollution level, and if the setting is changed to sensitive or insensitive, it is displayed higher or
lower than the default value.
▶The concentration of gas and dust displayed on the product measures the indoor environment real time, so it may
dier depending on the place of use, the measurement method of the environment, etc.
▶The maximum value of dust concentration displayed on the product is 500 ㎍/㎡.
▶The gas concentration displayed on the product is displayed in 1 to 4 spaces depending on the pollution level.
▶As the ultrasonic humidier has large humidifying droplet particles, the dust sensor can recognize them as dust,
thereby causing a malfunction in the dust sensor. So use it away from the purier.
▶If the dust pollution level continues to display the maximum number of 500, the sensor is contaminated. Therefore,
clean the dust sensor, turn o the power of the product and then turn on again so that it can operate normally.
▶The gas, PM 2.5 indication can keep the low indication value in a clean environment.
▶When the Plasma function operates, keep the lighting after dimming 5 times.

▶Auto mode
Operates eectively by automatically adjusting the air speed depending on the indoor pollution level detected by the sensor.
This is a convenient operating mode for most users.
Pollution Level Good (blue) Normal (green) Bad (yellow) Very bad (red)
Air speed Auto level 1 Auto level 2 Auto level 3 Auto level 4
▶Silent mode
Minimizes the air speed to create a quiet and comfortable environment.This is an operating mode with low noise and low power consumption.
In the silent mode, the speed indicator is o.
▶Eco mode
Based on the Auto mode, the fan stops operating for up to 30 minutes when it is held for 10 minutes at a dust level of 2 or less and a gas level of 1 or less.
If the indoor pollution level gets worse after continuously detecting the pollution level, the fan is immediately activated to purify the indoor air even when the fan is not in operation.
After the fan re-operates, if the indoor pollution level remains clean for more than 10 minutes, the fan repeats on and o.
▶Turbo mode
Maximizes air speed while operating to create a comfortable environment in a short period of time. The turbo operates at a higher air volume than the level
3 air volume.
※In the Turbo mode, noise may be higher.
▶Silent operation at night (Auto, Eco mode)
When the surroundings become dark for more than 3 minutes, the product is switched to the sleep mode (low speed, low noise, low power operation).
When the surroundings become brighter than more than 5 minutes, the sleep mode is canceled.
▶PLASMA
The antibacterial catalysis lter is activated with plasma light to reduce various odors and harmful gases generated in a room and create a comfortable
environment.
▶ION
Releases ions into the air and inactivates particulate matter oating in the room to reduce it.
- Plug the power cord into an outlet before operating the product.
- When the product is turned on, it is set to the previously operated mode.
