Airmega Mighty

¹ Coway air purifiers has been proven to trap dust, pollen, dander, viruses, and bacteria in the air based on KCL (Korea Conformity Laboratories) testing. They have been tested in a 30㎥-size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2018 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum fan speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.
² 99.9% of viruses, bacteria, fungi, and pollen were verified to be removed from the air by Coway air purifiers with GreenHEPA™ technology applied filters based on the Japan Food Research Laboratories (JFRL) testing according to JEM 1467 standard. Tested with AIRMEGA AP-1516D, AIRMEGA AP-1220B, AIRMEGA MIGHTY air purifiers and additionally AIRMEGA 150, AIRMEGA 250, AIRMEGA 300S, AIRMEGA 400S will acquire the test report in 1H, 2022. All tested by JFRL and received above result within below time.

• Virus: Tested with Escherichia coli phage ΦX174 NBRC 103405, 60 minutes 
• Bacteria: Tested with Staphylococcus epidermidis NBRC 12993, 60 minutes
• Fungi/Mold: Tested with Penicillium citrinum NBRC 6352, 60 minutes
• Pollen: Tested with Cedar Pollen extract, 30 minutes

Tested with Influenza A virus (H1N1) and Staphylococcus aureus on Coway’s Green HEPA filter media by Japan Food Research Laboratories (JFRL) and no growth was found on the material after 24 hours kept in room temperature.
Both tests were performed on small test pieces cut from the Green HEPA filter media, so this disclaimer can be used for any Coway products that use this filter.

• Virus: Tested with Influenza A virus (H1N1), 3cm x 3cm autoclaved piece
• Bacteria: Staphylococcus aureus, inoculated on 50mm x 50mm test piece. 

³ Tested with Human Coronavirus (HCoV-OC43) on Coway GreenHEPA™ technology applied filter media by BioPS Co., Ltd, a research organization specializing in viral clearance studies in South Korea. The test method was a filter media coupon test to observe the neutralization effectiveness. After 2 hours kept in room temperature, there was above 99.999% removal rate of the virus after the virus made contact with the filter media resulting in neutralization or inactivation of the virus is valid. Same result shows after 12 hours and 24 hours. This specific test was conducted with Human Coronavirus (HCoV-OC43) as the experimental model virus (Not Covid-19 (SARS-CoV-2)) because OC-43 is one of the seven types of Coronaviruses that can be infected to human Note: Air purifiers are known to be effective in preventing the Covid-19. However, it should never be regarded as the primary method of virus infection. Cleaning hands, trying to avoid contact and avoiding being in closed space in public is necessary to minimize the possibility of being affected by the possible virus infection. Coway supports every patient and medical staff around the world who work tirelessly to prevent and cure the spread of hazardous viruses.
* CADR (Clean Air Delivery Rate) of particulate matter is tested according to GB/T18801-2015 by a certified third-party lab. Measurement specifications are defined in GB/T 18801-2015, according to which two particle concentration decay rates have to be determined within a test chamber with a defined volume (Vchamber): a natural decay rate with inactive air cleaner (knat) and a decay rate detected under the measurements are carried out in a 30 ㎥chamber, which is empty except for the air cleaner placed on a table, two fans to mix and recirculate the air and some measurement periphery (mainly tubing). The chamber is kept at a temperature of 25 ± 2°C and a relative humidity of 50 ± 10%. Cigarette smoke is used as test aerosol and the number concentration of particles > 0.3 µm is measured using an optical aerosol spectrometer usage of the indoor air cleaner (kAC). The decay rates k is determined from the measured temporal decay of the particle concentration C(t), starting from the initial concentration C0:

* Room size is calculated according to NRCC-54013 standard using CADR tested according to GB/T18801-2015.

• NRCC: Method for Testing Air Cleaners
• Formula for room size: Room size = 0.26*CADR 

Note: The performance results may vary depending on the actual use environment of customers.
