The person in charge of product research and development of a well-known fresh air brand in the industry said: The new coronavirus generally uses droplets, aerosols, etc. as transmission carriers, and their volume is relatively large, and the diameter is generally more than 5 μm (microns). When these pollutants are sucked into the fresh air system by the airflow, they can be effectively filtered out by the HEPA high-efficiency filter, and the virus without the carrier will not survive. For example, in the general air fresh air system, the H13 high-efficiency filter inside can achieve a filtration efficiency of more than 99.97% for polluting particles with a diameter of 0.3 microns, which can effectively filter out pathogenic microorganisms including coronavirus.
In addition, he also said: “For high-efficiency filters, it is not that the smaller the particle size, the lower the filtration efficiency. Generally speaking, particles of 0.3 microns are the most difficult to remove, which is why the international standard has always adopted 0.3 Micron to measure HEPA performance.” He suggested that during the epidemic, keep the fresh air system running at home to suppress the risk of the spread of the new coronavirus, enhance protection, and create a healthy and safe breathing environment indoors.
