Assessment of a respiratory face mask for capturing air pollutants and pathogens including human influenza and rhinoviruses

Abstract

The masks, with or without features intended for enhancing comfort, provide protection against both small- and large-size pathogens. Importantly, the mask appears to be highly efficient for filtration of pathogens, including influenza and rhinoviruses, as well as the fine particulates (PM_2.5) present in aerosols that represent a greater challenge for many types of dental and surgical masks. This renders this individual-use N95 respiratory mask an improvement over the former types of masks for protection against a variety of environmental contaminants including PM_2.5 and pathogens such as influenza and rhinoviruses.
