- [Pre-print, not peer-reviewed] Face coverings were found to be more effective than face shields at blocking the small aerosol particles propelled by a cough aerosol simulator. The efficacy of blocking aerosols was 99% with an N95 respirator, 59% with a procedure mask, 51% with a 3-ply cloth face mask, 47% with a polyester neck gaiter and 2% with a face shield.
