Description

technical field

[0001] The invention belongs to the technical field of air filter performance testing, in particular to an air filter microbial filtration performance evaluation test bench for ventilation. Background technique

[0002] Microorganisms are a huge threat to human health. Microbial aerosols come from a wide variety of sources and are composed of different microorganisms. The pollutants in microbial aerosols are mainly composed of active particles and inactive biological pollutants. One of the main routes of transmission of atypical pneumonia is through droplet transmission. Microorganisms such as viruses and bacteria in the atmosphere can easily enter the human body through the respiratory tract, seriously threatening human health. At present, the most widely used air filtration technology is still to remove microbial aerosols. Microbial aerosols are removed from the air by the trapping action of the filter on the particulate matter. At this stage, many stu...
