Nanofiber filter captures almost 100% of coronavirus aerosols
Nanofiber filter captures almost 100% of coronavirus aerosols Afilter made from polymer nanothreads blew three kinds of commercial masks out of the water by capturing 99.9% of coronavirus aerosols in an experiment. “Our work is the first study to use coronavirus aerosols for evaluating filtration efficiency of face masks and air filters,” said corresponding author Yun Shen, a UC Riverside assistant professor of chemical and environmental engineering. “Previous studies have used surrogates of saline solution, polystyrene beads, and bacteriophages — a group of viruses that infect bacte...
