Abstract

Abstract

To study the impact of evaporation-condensation aerosol polydispersity on the penetration measurement experiment, the penetrations of various filter materials from low to high filtration efficiency were measured at different particle count median diameter and face filtration velocity. The true penetration curves at typical filtration velocity were obtained by corrected calculation, and compared with the test penetration, which was found that all the most penetrating particle sizes were all in the range of 0.1 μm to 0.3 μm. The most penetrating particle size measured in the test had a negative deviation, and the relative error with the corrected value was very small, with a maximum value within 1.5%. The extreme value of the penetration error caused by the polydispersity of the test aerosol appeared at the position of the most easily penetrated particle size, showing a negative deviation. The relative error of the low-efficiency filter material was small, with the minimum value of 2.4%, and the maximum value of the high-efficiency filter material was about 10%. It was concluded that in the range of the most penetrating particle size, the most easily penetrated particle size and penetration measured by evaporation-condensation monodisperse aerosol were valid.
