Wearing 2 masks doubles protection against Covid-19 virus: Scientists
Scientists now report that wearing two face coverings can nearly double the effectiveness of filtering out SARS-CoV-2-sized particles, preventing them from reaching the wearer s nose and mouth and causing Covid-19.
The reason for the enhanced filtration isn t so much adding layers of cloth but eliminating any gaps or poor-fitting areas of a mask, according to the study published in JAMA Internal Medicine. The medical procedure masks are designed to have very good filtration potential based on their material, but the way they fit our faces isn t perfect, said Emily Sickbert-Bennett, associate professor of infectious diseases at the University of North Carolina (UNC) School of Medicine and lead author of the study.
