For three years, the epidemic situation has been repeated and has had a great impact on people. Recently, American scientists wrote in the Journal of Exposure Science and Environmental Epidemiology that the possibility of air transmission of COVID-19 is 1000 times higher than that of contact with objects. The researchers detected the air and surface samples on the campus and found that compared with the contact of door handles, drinking fountains, keyboards, tables, sinks, electric switches and other surfaces, the probability of inhaling virus particles is greater than the probability of finger contact with infection, and the risk of inhaling virus is much higher.

As is known to all, droplets and aerosols are the main routes of COVID-19 transmission through the air. The droplet transmission mainly refers to the infection caused by the droplets when the virus infected person sneezes, coughs, speaks, smokes, and inhales the exhaled gas directly at a close distance. Aerosol transmission refers to the droplet particles ejected by the infected people when talking, coughing or sneezing, and the gas particles exhaled. The virus contained in the aerosol may remain in the environment for up to 48 hours, and the smaller the size, the more likely the aerosol will be to spread to a longer distance. Especially in the confined space, the propagation of aerosols will become more powerful. Because aerosols of small size can be suspended in the air for a long time, and will spread to a farther place with the flow of air.

How can we better prevent COVID-19 from spreading through the air? Some experts said that by disinfecting the air, the virus can be prevented from spreading through the air to the greatest extent.

Hohhot Research Institute Aobei non-equilibrium positive and negative oxygen ion release technology can inactivate various harmful bacteria and viruses in the air, such as COVID-19 and influenza virus, by releasing high purity and low concentration of active oxygen, with an effective rate of 99%. Hohhot Research Institute Aobai uses the strong oxygen (high purity and low concentration) effect of bionic composite particles to destroy the structure of microbial membrane, quickly kill various bacteria, effectively decompose and remove various odors, and create a fresh and clean indoor air environment for you. In addition, the active composite particles throughout the space can form a solid epidemic prevention barrier, which can effectively cut off the transmission route of the virus and reduce the risk of infection.

Earlier, academicians and experts in medical and health, electronic information and other fields in China unanimously said that the research achievements based on the active composite particle generation technology are highly innovative and difficult to study. The core key technologies are autonomous and controllable, and the technology is at the international advanced level. It is a new means of epidemic prevention and resistance for air disinfection and sterilization. The experts in the field of disinfection and hospital infection management of the National Health Commission also affirmed the effectiveness of the air disinfector, saying that it has good disinfection effect and green environmental protection characteristics, meets the health industry standards, has excellent disinfection performance, and is worthy of promotion and application.

The AOBAI non-equilibrium positive and negative oxygen ion release technology of Hohhot Research Institute is widely used in hotels, schools, hospitals, families, conference centers, offices, entertainment venues, chess and card halls, health care venues and other places related to large-scale activities. The feedback effect is good.
