초록
Control of fine particles in childcare centers, elementary schools, elderly care facilities and other locations where vulnerable people spend most of their time is essential. This study investigated PM2.5 and PM10 concentrations in two classrooms equipped with one and two air cleaners, respectively, compared with concentrations outdoors and in a classroom with no air cleaner. Eight models of air cleaners with clean air delivery rates ranging from 9.9 to 21.3 m3 min–1 were tested in the classrooms of two elementary schools in Seoul. Average PM2.5 and PM10 levels were 7.3 ± 0.7 and 45.5 ± 4.1 µg m–3 in classrooms equipped with one air cleaner and 4.2 ± 0.6 and 24.6 ± 2.5 µg m–3 in classrooms with two air cleaners, whereas they were 22.1 ± 2.6 and 109.1 ± 9.6 µg m–3 in classrooms with no air cleaner and 36.9 ± 5.1 and 74.1 ± 10.6 µg m–3 outdoors, respectively. The PM2.5 level in classrooms …
