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.
L'informe de CITIC Securities va assenyalar que, actualment, l'escala dels sistemes d'aire fresc domèstic supera els 10.000 milions, la taxa de creixement composta és d'uns 30%, la taxa global de concordança de la indústria és inferior al 10% i el canal d'enginyeria és d'un 15%. Impulsada per la millora de la consciència i l'acceleració de les polítiques, l'escala terminal a llarg termini de la indústria de referència a l'estranger pot arribar als 100.000 milions de iuans, un augment de deu vegades.
