    Ability of fabric face mask materials to filter ultrafine particles at coughing velocity by James Ward, P John Clarkson, Eugenia O'Kelly, Sophia Pirog

    Published 2020-09-01
    “…Objective We examined the ability of fabrics which might be used to create home-made face masks to filter out ultrafine (0.02–0.1 µm) particles at the velocity of adult human coughing.Methods Twenty commonly available fabrics and materials were evaluated for their ability to reduce air concentrations of ultrafine particles at coughing face velocities. …”
