Testing principle: The filtering efficiency is measured by continuously penetrating the filtering element with particles of specified concentration and particle size distribution under a certain air flow, and measuring the "loading" filtering efficiency, i.e., simulating the efficiency in the actual use process, when the particles have a certain amount of deposition (dust capacity) on the filtering material.
