Abstract : This research focuses on designing a novel, five‐layered N95 mask fabric that integrates the natural antimicrobial properties of Boswellia serrata , thereby unlocking a new dimension in respiratory protection. Specifically, the second and third layers of the mask fabric were coated with a chloroform extract of Boswellia serrata to impart layer‐specific functionality. The functionalized mask fabrics underwent rigorous analysis, including Scanning Electron Microscopy (SEM), Energy Dispersive X‐ray (EDX) Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), and wettability measurements, confirming the successful incorporation of the extract. The contact killing assay demonstrated a highly effective dual‐action defense system. The extract‐coated second layer exhibited a rapid, but transient, antimicrobial effect, showing excellent inhibition within one hour (92% against S. aureus , 86% against E. aerogenes ), though this effect diminished significantly by eight hours. In contrast, the third layer provided a prolonged and sustained antimicrobial effect, maintaining high inhibition even after eight hours (100% against C. albicans and K. pneumoniae , and 90% against E. aerogenes ). Maximum killing efficiency was observed at four hours for both layers. This innovative application of layer‐specific engineering offers enhanced and prolonged protection against airborne pathogens, marking a significant leap in mask technology.
