Effects of Different Test Media on the Test Results of Automobile Cabin Air Filter

ABSTRACT

Automobile cabin air filters have been ever-increasingly detected since the outburst of COVID-19. However, the dust sources adopted are varied due to the numerous standards. In this study, the effects of different dust sources on the test results of filtration efficiency were explored, and the causes for the different test media used in different standards were analyzed. The study results provide a reference for further improving the performance of vehicle cabin air filters. © 2021 SPIE
