What air disinfection methods can be used to disinfect the air in the presence of people?

Ozone has a good disinfection effect on indoor air microorganisms and can also remove odor, so it is convenient to use. Under the condition of relative humidity ≥ 70%, the concentration should be ≥ 20 mg/m3, and the disinfection time should be ≥30min. Ozone is toxic to people and corrosive to metals and rubber.

Natural ventilation is the most economical, simple and effective way to keep indoor air fresh and reduce bacterial concentration. Anyone can use it. It is of great significance to prevent the spread of SARS.

After the emergence of respiratory infectious diseases, even if a single air disinfection method kills all microorganisms in the air, it does not kill microorganisms that pollute the surface, and it will soon pollute the air. In this case, the more reasonable method should be to disinfect the surface of the object and the air at the same time, and you can choose disinfectants such as peracetic acid or hydrogen peroxide for spraying or fumigation.

As an air disinfection method when people are around, you can choose a circulating air sterilizer or an electrostatic air sterilizer for continuous dynamic disinfection. When using this air disinfection method, we should combine the sanitary cleaning treatment of indoor surfaces or disinfect the polluted surfaces with disinfectant first to ensure the air disinfection effect.

Significance of air disinfection

Family: Avoid putting a lot of extra burden on human immune system due to poor indoor air, causing physical fatigue and reducing productivity and work efficiency. Reduce immune system diseases induced by air pollution, such as leukemia, asthma and emphysema, and promote human physical and mental health.

Factory: Air disinfection is used in the production of food, cosmetics and medicines. To prevent the secondary pollution of bacteria in the air during production, cooling, filling and inner packaging, and ensure the quality and safety of products.

Hospital: effectively control the secondary pollution caused by air flow between departments and sick rooms, reduce the secondary cross-infection between patients and nursing staff, patients and medical staff, and make patients recover quickly.
