The Effect of Students, Computers, and Air Purifiers on Classroom Air Quality

Indoor air pollutant sources are crucial in assessing IAQ, especially when outdoor concentrations low. In the present study, PM mass a range of five sizes; CO, CO2, O3, NO, NO2, and TVOC concentrations; along with temperature relative humidity were monitored three indoor locations university. The monitoring took place building dedicated to teaching undergraduates. first two locations, professor’s office computer centre (laboratory), not refurbished. classroom under study is refurbished now airtight, as all classrooms this building. Air purifiers installed prevent transmission infectious pollutants. people main source PM, TVOC. operation twelve computers small laboratory did contribute pollution, at least for examined purifier decreased concentrations, but gaseous
