Abstract：
Based on the testing experience and data of air cleaning devices, proposes a testing method for PM2.5 purification efficiency of air cleaning devices for ventilation systems. Discusses the testing method in detail from the generation of testing aerosol (such as aerosol types and aerosol generator), the performance of PM2.5 purification efficiency testing bench (such as airflow stability, air velocity uniformity, PM2.5 concentration uniformity and PM2.5 concentration stability) and the selection of PM2.5 testing instruments.
