4D Particulate Filter

Removes over 90% of ultrafine dust particles (0.01μm)
Control air flow with Noble’s Air Pop-Up panel.
360º airflow for a thorough clean.
Suitable for when you want to clean the entire space evenly by circulating clean air at 360º
Suitable for when you want to quickly and intensely clean a highly polluted living space.
Good for maintaining the air quality while providing a soft breeze to purify and soothe your living space.
Pet Mode to control dust and allergens
Unique circulation mode to effectively lift dust, hair, and allergens from the floor and remove them.
Step 01
Lift the Dust
Strong front focused airflow lifts dust, hair, and allergens from the floor.

Step 02
Remove dust from across the room
The optimized 13º angle draws in dust and fur in from across the room.

Step 03
Remove close-range dust
Finally, the Full Circulation Mode removes any leftover dust and contaminants.
*Fur removal performance depends on type and breed of pet.
*Actual performance depends on usage environment.

Powerful filtration system
99.9% removal of 0.01㎛ fine particles
Coway’s four-stage differentiated filter system reduces ultra-fine dust and odors to keep indoor air clean. It also provides a powerful dual-power system for inhaling contaminated air and a front-facing accumulator for fresh air to provide faster, finer air handling.
*Tested by Kimm (Korea Institute of Machinery and materials) 99.9% removal of 0.01 ㎛ microparticle (*at maximum airflow in the airtight chamber for more than 60 minutes) (2018.07.20 by KIMM report)
1. Performance tested by KIMM (Korea Institute of Machinery and Materials), to measure how long it takes to remove 99.9% of the 0.01㎛ fine particles when operating the air purifier, Operated to measure the particle reduction rate over time (according to the internal standard of the KIMM) of the AP-1018F model (recommended coverage area 33m2 with filters), in chamber and under environmental conditions of the Korea Air cleaning Association (SPS-KACA 002-132, Indoor air purifier performance Test) after providing 10nm (0.01㎛) of particles into the chamber.
2. Particle removal rate by an air purifier operation is tested until the background concentration of 0.01㎛ particles reaches 1 X 105/cm3 in the test chamber (30.4 m3) at temperature (℃) 20 ±1 / Relative Humidity (%) 48 ± 1 %
3. The fine particle removal rate is tested in an airtight laboratory environment by a specific model of an air purifying device. Actual performance and test are subjected to change depending on the region and product specification.
*As a result of testing CA certification standards, the removal rate of removal of harmful gases is 93%. (30 minutes of operation in the chamber), (Based on 2018.05.03 CA Certificate)
1. Harmful gases removal test is based on CA certification by the Korea Air Cleaning Association (SPS_KACA 002-132:2018, indoor air purifier removal test), AP-1018F model (recommended coverage area 33 m2 with filters) for Ammonia, Acetic acid, Acetaldehyde, Toluene, Formaldehyde
2. Tested in the chamber (8.0 m3) at temperature (℃) 23 ±5 / Relative Humidity (%) 55 ±15, and for deodorization test. The initial concentration of gas for testing is 10 ppm and the tolerance for concentration is 10%.
3. The harmful gas removal rate is tested in an airtight chamber laboratory environment by a specific mode of an air-purifying device based on a test standard of the Air Cleaning Association. The test is subject to change depending on the region and product specifications.
