a Diagrams of heat and moisture transfer of dual-scale fibrous filter and its antibacterial mechanism. b Water vapor transmission, (c) air permeability and (d) infrared transmittance of dual-scale fiber filter, MM and MBM. e Surface temperature of face mask during the respiratory cycle. f IR images of dual-scale fiber filter, MM, MBM, KN95 mask. g Quantitative antibacterial images and (h) antibacterial rate of blank sample and dual-scale fiber filter. i SEM images of live and dead bacteria. Error bars represent the standard deviation of the measured properties and the samples are samples are at least three. Source data are provided as a Source Data file.
