Control: Use face shields

Efficacy of face masks, neck gaiters and face shields for reducing the expulsion of simulated cough-generated aerosols


This study used a cough simulator with a headform to propel small aerosol particles into different face coverings.  The N95 respirator blocked 99% of the cough aerosols, a procedure mask blocked 59%, a 3-ply cloth face mask blocked 51%, and a polyester neck gaiter blocked 47% as a single layer and 60% when folded into a double layer. The face shield only blocked 2% of the cough aerosol. This article has not been peer-reviewed. (October 2020)
