A COVID-19 epidemic has not only severely affected the normal pace of work and life of the Chinese people, but also made everyone re-recognize the importance of daily health protection! As the epidemic gradually stabilizes and even subsides, all parts of the country will usher in the “window period of resumption of work” “. In addition to the necessary mask protection in outdoor spaces, everyone also needs to pay special attention to the indoor environment of the workplace. Because in the use of central air-conditioning or inconveniently ventilated confined spaces, the spread and persistence of the virus cannot be ignored. As the “first line of defense” in the indoor environment-can air purifiers effectively filter out viruses? It has become one of the focuses of attention from all walks of life.
In response to this problem, Mr. Dai Zizhu, a researcher at the Institute of Environmental and Health Related Product Safety of the Chinese Center for Disease Control and Prevention, and an expert in the field of environment and health, said: During the epidemic, in addition to strengthening ventilation, HEPA high-efficiency filtration with H12 and above should also be used. Use it to filter the aerosols and droplets with viruses in the air to clean the air. As a result, the value of high-standard air purifiers will appear.
So what kind of air purifier is considered a high standard? You can judge from the following three points:
First, is there any third-party authority testing and certification for virus removal capabilities?
Recently, there are reports that “the air purifier product standard does not have a requirement for virus killing rate, and it may not be suitable for filtering viruses.” This also strongly reminds us that since the product has not formulated this standard, it should be passed the first. Authoritative testing by tripartite agencies, after actual testing, can effectively filter out the air purifier is worth choosing. The classification mechanism of HEPA filter is diversified. Many product manuals or e-commerce pages do not indicate the diameter range that can filter the pollution source, and even if it is indicated, it is only a theoretical value. Therefore, it is more credible to obtain the inspection and certification of a third-party authority.
Second, to see if the HEPA filter element level of the air purifier reaches H12 or above?
Some air purifier products on the market are equipped with HEPA filters, which are interwoven with very fine organic fibers, which have a strong ability to capture particles (including aerosols), small pores, and high purification efficiency. Of course, the HEPA filter also has a detailed classification, and different levels have different filtration efficiencies for particles of different diameters.
According to authoritative testing organizations, air purifiers with MERV16 or H12 and above and with antibacterial coating high-efficiency HEPA filter elements can filter out H1N1 viruses up to 99.99%. The reason why air cleaning has such a high removal rate of viruses is because it intercepts most of the aerosols and droplets, making the virus unable to escape.
According to the information released by the Chinese Center for Disease Control and Prevention, the size of the new coronavirus is about 100 nanometers, which is similar to the size of the H1N1 virus (the size of the H1N1 virus is 80-120 nanometers), and the two are also attached to aerosols or in the air. Droplets are present.
In view of the similar diameter and the shared transmission route, if the air purifier is equipped with a high-efficiency HEPA filter element of MERV16 or H12 and above and has an antibacterial coating, it can effectively filter out the H1N1 virus by 99.99% in a confined space through circulating purification. For viruses of approximately H1N1 size, and viruses carried on aerosols, it should also be filterable.
Third, see if the HEPA filter element has an antibacterial coating?
Simple physical filtration will cause the risk of secondary pollution caused by residual pollutants. The high-efficiency HEPA filter with an antibacterial coating can ensure that the breeding and reproduction of microorganisms can be effectively inhibited, secondary pollution can be avoided, and the particulate matter at the air outlet can be close to zero.
At the moment of the epidemic, prevention is indispensable, but if you want to establish a “city wall” defense line to prevent viruses indoors, then equipped with a high-standard air purifier that has been tested and certified to filter out the virus, it is the indoor protection of the epidemic. One of the important means. If you want to know more about the air purifier, please consult Olansi immediately.
