\u00b9 Based on tests conducted by KCL (Korea Conformity Laboratories), Coway air purifiers capture dust, pollen, dander, viruses, and bacteria from the air. They have been tested in a 30 \u33a5 chamber in accordance with the Korean Air Purifier Association standard (SPS-KACA 002-132:2018, modified) to measure the removal rate of 0.01 \u339b particles. The test was conducted at the fan\u2019s maximum speed under normal room temperature and humidity conditions. Performance may vary in the customer\u2019s actual environment. <\/p>\n
\u00b299.9% of viruses, bacteria, fungi, and pollen were removed from the air using Coway air purifiers equipped with filters featuring GreenHEPA\u2122 technology, which was tested by the Japan Food Research Laboratories (JFRL) in accordance with the JEM 1467 standard. The following models were tested: AIRMEGA AP-1516D, AIRMEGA AP-1220B, AIRMEGA MIGHTY, as well as AIRMEGA 150, AIRMEGA 250, AIRMEGA 300S, and AIRMEGA 400S. <\/p>\n
All of them took the JFRL test and achieved the results listed above within the time limit specified below:<\/p>\n
Virus: Tested with Escherichia coli phage \u03a6X174 NBRC 103405, 60 minutes
\nBacteria: Tested with Staphylococcus epidermidis NBRC 12993, 60 minutes
\nFungi\/mold: tested with Penicillium citrinum NBRC 6352, 60 minutes
\nPollen: tested with pine pollen extract, 30 minutes<\/p>\n
The Coway Green HEPA filter was tested for influenza A (H1N1) and Staphylococcus aureus (by Japan Food Research Laboratories (JFRL)), and no growth was observed in the material over a 24-hour period at room temperature.<\/p>\n
Both tests were conducted using small test specimens cut from green HEPA filter material; therefore, this conclusion can be applied to all Coway products that use this filter.<\/p>\n
Virus: Tested with influenza A virus (H1N1), a 3 cm x 3 cm autoclaved piece
\nBacteria: Staphylococcus aureus, inoculated onto a 50 mm x 50 mm sample.<\/p>\n

\u00b3Tested with human coronavirus (HCoV-OC43) Using a filter media incorporating Coway GreenHEPA\u2122 technology, tested by BioPS Co., Ltd., a South Korean research organization specializing in virus removal studies. The test method used was a filter material coupon test to monitor neutralization efficiency. After two hours of treatment at room temperature, following exposure of the virus to the filter medium, more than 99.999% of the virus was removed, resulting in the neutralization or inactivation of the virus. The same results were observed after 12 hours and 24 hours. This specific test was conducted using the human coronavirus (HCoV-OC43) as an experimental model virus (not COVID-19 (SARS-CoV-2)), since OC-43 is one of seven types of coronaviruses that can infect humans. <\/p>\n
Note: Air purifiers are known to be effective in preventing COVID-19. However, they should never be considered the primary method of preventing viral infection. Hand hygiene, social distancing, and avoiding enclosed spaces in public places are essential for minimizing the risk of viral infection. Coway supports all patients and healthcare workers around the world who are working tirelessly to prevent and treat the spread of dangerous viruses. <\/p>\n
* The unit’s CADR (Clean Air Delivery Rate) has been tested in accordance with GB\/T18801-2015 at a certified third-party laboratory.<\/p>\n
The measurement specifications are defined in GB\/T 18801-2015, according to which two particle concentration reduction rates must be determined in a fixed-volume test chamber (V-chamber): the natural decay rate with an inactive air purifier (knat) and the decay rate observed during measurements conducted in a 30 \u33a5 chamber\u2014which was empty except for an air purifier placed on a table, two fans for air mixing and circulation, and some external measurement equipment (primarily tubes)\u2014two decay rates were observed. The chamber temperature is maintained at 25 \u00b1 2 \u00b0C and the relative humidity at 50 \u00b1 10%. Cigarette smoke is used as the test aerosol, and the particle number > 0.3 \u00b5m is measured using the optical aerosol spectrometer of the indoor air purifier (kAC). The decay rates k are determined based on the measured temporal decay of the particle concentration C(t) from the initial concentration CO: <\/p>\n
* The room size is calculated using the NRCC-54013 CADR test in accordance with GB\/T 18801-2015.<\/p>\n
NRCC: Test Method for Air Purifiers<\/p>\n
Formula for room size: Room size = 0.26 \u00d7 CADR<\/p>\n
Note: Performance results may vary depending on the actual working environment of customers. <\/p>\n
* The Coway Green-HEPA filter is treated with the biocides thiabendazole and silver sodium zirconium hydrogen phosphate to create an antibacterial surface. This prevents the growth of mold, viruses, and bacteria, which extends the filter\u2019s lifespan. <\/p>\n","protected":false},"excerpt":{"rendered":"
