(1) Coway air purifiers purify the air from dust, pollen, dander, viruses and bacteria according to tests by KCL (Korea Conformity Laboratories). The air purifiers have been tested in accordance with the standards of the Korea Air Cleaning Association (SPS-KACA 002-132: 2018 Modified) in a 30? Room to measure the particle removal rate of 0.01? The test took place at maximum fan speed under normal room temperature and under normal humidity conditions. The performance may vary in the actual living environment of the customer.
Test chamber is carried out. Except for the air filter placed on a table, this test chamber is empty. Two fans mix and circulate the air. In addition, there are a few measuring devices (mainly hoses) in this chamber.
The chamber is kept at a temperature of 25 (± 2 ° C) and a relative humidity of 50 (± 10%). Cigarette smoke is used as the test aerosol and the number of particles> 0.3 µm is measured using an optical aerosol spectrometer using the indoor air filter (kAC).
The decay rates "k" are determined from the measured decay of the particle concentration C (t) over time based on the initial concentration C0: (3) The room size is calculated according to the NRCC-54013 standard. NRCC (National Research Council Canada): Method for testing air purifiers - Formula for room size: Room size = 0.26 CADR 99.9% of viruses, bacteria, fungi, and pollen were verified to be removed from the air for Coway air purifiers which has a GreenHEPA filter applied based on the Japan Food Research Laboratories(JFRL) testing according to JEM 1467 standard. Tested with InfluenzaA virus (H1N1) and Staphylococcus aureus on Coway's GreenHEPA filter media by Japan Food Research Laboratories (JFRL) and no growth was found on the material after 24 hours kept at room temperature.
The test results may vary depending on the actual usage environment of the customer. Air quality display and automatic operation. Thank You For Your Business!
