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. When layered over procedure masks, cloth masks improve fit by eliminating gaps and holding the procedure mask closer to the face, consistently covering the nose and mouth.
