Experience the unique filtering technology by COWAY. This technology generates a large amount of oxygen atoms and high energy electrons to effectively remove pollutants in indoor environments. The performance and life of the AC deodorizing filter is enhanced while suppressing the generation of ozone, and results in clear refreshing air.

Resisted Barrier Discharge Plasma Filtering

Coway's air purifiers unique RBD (Resisted Barrier Discharge) Plasma filtering system generates a large amount of oxygen atoms and high energy electrons to effectively remove indoor air pollutants such as cigarette smoke and micro dust to provide the consumer with fresh air in your home or office. The perfomance and life of the A/C deodorization filter are enhanced while it suppresses the emissions of ozone.

Coway's 5 Steps to Pure Air

Coway's advanced air purifier technology consists of 4 basic filters and the consumers choice of one custom filter to fit their specific environment.

Step 1-Pre-Filter removes large dust, sand and hair by using a filter made up from anti-bacterial materials.

Step 2-Medium Filter removes particles, mold and bacteria larger than 1 micrometer.

Step 3-Advanced Hepa Filter eliminates fine dust, viruses, germs and cigarette smoke. Through the hepa filter 99.97% of invisible dust, various viruses and other pollutants are eliminated.

Step 4-Custom filter- the consumer chooses to fit their specific environmental needs.

New House Filter-Removes formaldehyde, and other VOC's. This filter also prevents Sick House Syndrome, which presents as symptoms such as headache, blurry eyes, runny nose, and atopic dermatitis. It utilizes Pt (Platinum) Catalyst technology to remove harmful substances that cause New House Syndrome

Legionella Filter-Eliminates 99.99% of legionella, a bacteria that causes several diseases in the summer time. Legionella bacteria exists in places such as air conditioners and can easily effect respiratory organs.

Yellow Sand Filter-Eliminates 98.9% of yellow sand, micro sand and atmospheric pollutants such as SOx (Sulfer Dioxide), NOx (Nitrogen Oxide), and other pollutants through the use of a micro pore filtration technology.

Human Influenza Filter-Eliminates 99.9% of the human influenza virus and was developed for children with weak immune systems.

Allergen Filter-Removes allergens such as ticks and mountain cedar.

Step 5-Deodorization Filter efficiantly eliminates bad odors and harmful gases.

The dangers of influenza virus
Hong Kong Influenza Virus: An influenza that originated from Hong Kong in 1968, led to the deaths of approximately 700,000 people worldwide. In the U.S., it caused the death of approximately 30,000 people.

Avian Influenza Virus
The virus is mainly infected in birds. Depending on the type of virus, the infection and mortality rates vary. In some cases, the virus can spread to humans. So far, its caused the deaths of 6 in Hong Kong (1997), 16 in Vietnam (2004)

Legionella, which threatens summer health, occurs easily in air conditioners and infects through the respiratory system. Eliminating 99.9% of legionella, which is the source of legionnaires, the Legionella Filter is an essential purification system necessary for elders and children with weak immune systems.

The Yellow Dust Filter, which eliminates 99.8% of yellow dust, micro dust, Sox attached to dust, NOx, and spring time atmospheric pollutants, delivers refreshing healthy spring air to the entire house.

Yellow Sand
Asian dust is a sand dust that flies all
the way across from Northern China and Mongolia during the spring time. It is
known to contain high concentrations of sand, heavy metals, and toxic gas.During
this season, the dust concentration severely increases in Korea, China, and
Japan, leading to higher occurrences of health problems such as rhinitis.

New House Filter for new homes effectively removes substances that lead to Sick House Syndrome, which is known as the main cause of atopic dermatitis. Using a white gold catalyst and AC deodorizing filter that effectively eliminates the formaldehyde and volatile organic compounds, the filter only leaves behind the joy of living in a new home.

Sick House Syndrome
Also known as the Building Syndrome, the Sick House Syndrome is caused by toxic gas (VOC's, HCHO) in newly built apartments and buildings. It causes headaches, blurry eyes, and rhinitis. Over time, the emission of toxic gas causing the building syndrome reduces, but studies report that it can emit toxic gas up to 4 years.
