Abstract The filtration of airborne particulate matter (PM) and aerosols utilizing nonwoven fibrous materials has received significant research concern due to the continuing global pandemics, especially outbreak coronavirus disease (COVID-19), particularly for face masks as a measure personal protection. Although spun-bond or melt-blown fabrics are among pioneer in development polymer microfiber-based air filters on large scale, relatively new manufacturing processes like electrospinning solution blow spinning (SBS) gaining momentum manufacturers filter membranes. high performance nanofiber is their surface area volume ratio which increases interaction between PM improves electrostatic charge distribution electret filters, allowing enhanced capture capability based deposition. Moreover, small diameter nanofibrous breathability mask by providing slip effect, turn reduces pressure drop through membrane. This paper provides comprehensive review contemporary advances masks, detailing working mechanism involved, reviewing recent experimental studies, discussing improvements efficiency three main strategies, including mechanical antimicrobial functionality. Furthermore, prospective introduced considers synergistic combination effects mechanisms designing multifunctional structure that can efficiently wide range with higher lower drops pressure. New trends activity smart material-based membranes fight against infectious agents also described.
