Nanofibrous filters: A promising solution for the efficient capture of polydisperse viral aerosols.

ABSTRACT: This study investigates the effectiveness of electrospun nanofibrous filters in capturing polydisperse virus-containing aerosols and the subsequent release of viruses, in comparison with standard commercial filters used in respirators, military gas masks, and devices for airborne virus sampling. We assessed the performance of these filters in capturing and releasing polydisperse aerosols containing MS2 bacteriophage, as well as in their ability to filter monodisperse dioctyl phthalate aerosols measuring 0.185 μm and 0.3 μm in diameter. Our findings indicate that nanofibrous filters provide superior filtration efficiency for monodisperse aerosols, achieving a reduction in the concentration of penetrating aerosols by 2-3 orders of magnitude compared to their commercial counterparts. However,
