Physicist Uses a Cotton Candy Machine to Make Respirator Filters for N95 Masks Cheaper


A graduate student in physics is creating the most effective face mask, the N95, with little more than a wave of his hand. Using a cotton candy machine, Mahesh Bandi of Okinawa Institute of Science and Technology Graduate University can create face masks more cheaply and faster than any other currently utilized industrial process. That’s because the unique but expensive electrocharged plastic foam filters that characterize an N95 can actually be made by taking lumps of regular plastic from objects like water bottles and shopping bags, heating them to a high temperature, and spinning them in a cotton candy machine until they form a mesh.
