As most nations are rocked with the second or third wave of the novel coronavirus, the findings of the study published in JAMA Internal Medicine on April 16 has stated that the reason for the enhanced filtration of two masks is not about adding too many layers of cloth but eliminating any gaps of poor-fitting areas of the mask.

COVID-19: Wearing two masks doubles protection

Fit matters most when double masking to protect yourself from COVID-19

Credit: UNC School of Medicine CHAPEL HILL, NC - A study published today in JAMA Internal Medicine shows 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. 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, PhD, associate professor of infectious diseases at the UNC School of Medicine and lead author of the study.
