Facemasks Block Expired Particles, Despite Leakage

Caption

A new study from UC Davis and the Icahn School of Medicine at Mount Sinai confirms that surgical masks effectively reduce outgoing airborne particles from talking or coughing, even after allowing for leakage around the edges of the mask. Professor Chris Cappa of UC Davis tests a mask by speaking in front of a particle counter.
