Motivated by the current pandemic we analyze the use of cloth masks as effective alternatives to medical masks for the general public. In this paper, we establish a quantitative framework for estimating the filtration efficacy of cloth masks by deriving analytical estimates for the pressure drop across woven heterogeneous fabrics. We then introduce a filtration quality factor to compare the intrinsic filtration capabilities of diverse materials for submicron aerosols. Finally, we present a decision map to illustrate the trade-offs between filtration efficiency and breathability and to provide practical guidance on the selection of cloth masks. |
