AIRMEGA 400

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

* 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.
