The research on the transmission of influenza viruses in the air shows that the viruses are mixed with dust and haze particles, involved in the atmosphere and transmitted in a long distance. The presence of haze results in a significant increase in the influenza virus content in the air, 21 to 31 times that of clean air. Researches show that the survival rate of the attached and combined influenza virus and haze particles is enhanced, and the long-range transmission of the influenza virus is facilitated. Teachers in kindergartens and primary and secondary schools are the main places for spreading viruses, so that a technology capable of comprehensively, efficiently and thoroughly removing haze and sterilizing in classrooms is needed.
However, the existing methods for removing haze and sterilizing are all independent processes of removing haze, removing formaldehyde or sterilizing, and cannot utilize a unified system to remove haze, remove formaldehyde and sterilize indoor air according to indoor actual use conditions, so that the indoor air is polluted and viruses are spread.
