At present, under the situation of strictly controlling the import of overseas cases, COVID-19 cases have rebounded in local areas, and the epidemic prevention situation is still very serious. Consciously wearing masks, keeping social distance and reducing gatherings can effectively reduce the risk of virus transmission through droplets and contact, but the mode of air transmission has never been paid attention to. Airborne pathogens have a long survival cycle in the air and can spread over long distances with the air flow. In crowded or poorly ventilated spaces, once an infected person appears, the virus will quickly spread through particles in the air, causing a large-scale infection in a short time. Therefore, equipped with professional disinfection equipment that can kill the virus flowing in the air is very critical to prevent the spread of the virus indoors and in places where people gather.

Cleanbao® series air disinfection equipment independently developed and produced by Shanghai Cleanbao Environment Science & Technology Co., Ltd., a wholly-owned subsidiary of Yuanda-llongwill(securities code: 430511), produces safe and efficient chlorine dioxide disinfection gas in real time, and disinfects at anywhere and anytime, effectively blocking the transmission of virus through the air. It is widely used in schools (kindergartens), office buildings, medical institutions, restaurants, hotels, large transportation hubs and other public places.
