Indoor pathogenic microorganism aerosol pollution and air disinfection and purification technology

Some viruses and bacteria can survive in the air for a long time and spread widely in the form of aerosols. As the pathogens of some infectious diseases, they may cause the epidemic outbreak or out of control, and have a great impact on public health. So air disinfection and purification technology is necessary. Summarizes the classification and principle of air purification technology and the application of professional purification equipment to air conditioning system, and compares the effectiveness and stability of various technologies, which can provide a reference for the selection of air purification methods in the future.
