During the current COVID19 pandemic, the sudden surge in demand coupled with broken supply chains have resulted in severe shortage of personal protective equipment (PPE) such as face masks, and medical apparel. Meltblown filter media arecritical functional material employed to filter micro-organisms including virus. Although this technique has been in commercial practice for over half a century (Wente 1956, Buntin et al. 1970), continuous advances in technology have enabled highly functional articles capable of specific usein filtration, waterproof fabrics, medical gowns and sorbents. This talk details the history of technology of meltblowing and showcases the efficacy of the technique in fighting microbial pandemics. A broad survey of related developments is presented to inform the wide audience in the wake of a revival of this technology in the western hemisphere.
