Abstract：
Introduces in briefly the development of testing methods of the air filter and the evaluation of related standards at home and abroad in recent years. Presents the classification curve proposed by the authors and the main classification methods for foreign and domestic ventilating air filters. Performs the comparison of different classifications at home and abroad, providing references for the design and selection of ventilating air filters.
