This study investigated the influence of the operating conditions on an air purifier and extra FAN efficiency in reducing particulate matter in a classrooms. Computational fluid dynamics (CFD) simulation considering three locations of Air purifiers and operating conditions of four FANs was conducted to evaluate the optimal operating condition. In this study, the Clean Air Delivery Rate (CADR) of Air purifier was 2.4 m3/min (161.4 CMH) and 4.8 m3/min(322.8 CMH). Assuming the indoor particulate concentration is 150 μg/m3, the performance of reducing particle concentration varies by a maximum of 31.2% depending on the position of the air purifier and the operating condition of the FAN. When the CADR of the air purifier is low, particulate matter reduction performance can be improved by a FAN. When using the FAN, make sure that it does not interfere with the airflow of the air purifier.
