Abstract

This study evaluated the fine particulate matter concentrations and airborne infection risks in the classroom of elementary school due to various environmental and behavioral conditions. Simulation model was established by mass-balance equations and Wells-Riley equation. The indoor air pollutants are CO2, PM2.5, PM10, SARS-CoV-2. The ventilation system with HEPA filter and air purification system are set to air cleaning devices. In addition, occupants mask types are considered. To remove particulate matters (PM 2.5 and PM 10), ventilation system showed limited effects, and air purification system with HEPA filter can be good solution. Airborne infection risk by SARS-CoV-2 can be reduced by wearing masks and adopting ventilation system and air purification system. Wearing N95 mask showed drastic infection risk reduction. Ventilation system that already installed to classroom also good performance to reduce infection risk. Air purification system also shows marginal infection risk reduction, in current classroom setting.
