Powerful Filtration System
The powerful dual power system and 14 filters draw in polluted air from both the front and rear sides of the unit, then release purified air through the top of the product, providing faster and more efficient air purification for the air you breathe.
Quattro Power System
The Quattro Power System features dual motors, dual fans, and 14 filters to deliver powerful and stable air purification. In addition, Coway’s advanced aerodynamic technology provides a clean air solution designed with both your home and the environment in mind.
Turbo Circulation Mode
Fast and powerful purification from nearby areas to distant spaces.
Intensive Circulation Mode
Focused purification for nearby air.
Wide Circulation Mode
Provides balanced and thorough purification throughout wide spaces.
Powerful Filtration System
Over 90% 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) over 90% 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 over 90% 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.
Low Noise Design
The low-noise design minimizes noise and vibration, providing a quieter and more comfortable environment.
Ultra Air Purifier Q&A
A: The Ultra Air Purifier is optimized for large spaces and can cover up to 1,496 ft² (138 m²) at 2 air changes per hour (ACPH), or up to 2,992 ft² (277 m²) at 1 air change per hour. It is suitable not only for living rooms, but also for large commercial spaces such as offices and cafés.
A: It is a system equipped with dual motors, dual fans, and a total of 14 filters that powerfully draw in polluted air from both the front and rear sides of the unit. Through this process, purified air is quickly discharged through the top, rapidly improving indoor air quality.
Through Coway’s differentiated 4-stage dual filtration system, the purifier removes over 90% of ultrafine particles as small as 0.01㎛ while effectively reducing fine dust and everyday odors. Its performance has been verified through testing conducted by the Korea Institute of Machinery and Materials (KIMM).
A: Yes. It supports multiple circulation modes, including Turbo Circulation for quickly purifying air even from distant areas, Intensive Circulation for focused purification of nearby spaces, and Wide Circulation for balanced purification across large areas, allowing customized air cleaning based on your needs.
