As the risk of fine dust in Korea increases, physical education classes are held in large indoor spaces more frequently. Indoor air quality of the large space is important because children are vulnerable to fine dust. In this study, air jet systems with air purifying function applied to large space of school were analyzed with respect to PM2.5 and CO₂ concentrations. The PM2.5 concentration reduction effect was noticeable with the jet air conditioning system operation. However, concentration change of CO₂ was minimal.
