While cloth face coverings do not offer a way to filter the air that the user breathes in or exhales, they offer a layer of protection against the spread of COVID-19. The coronavirus is spread through respiratory droplets present when talking, sneezing, or coughing. A cloth face-covering protects the wearer by creating a barrier between the respiratory droplets and the wearer, thus preventing the droplets from entering the wearer's respiratory system. It's important to note that the face-covering must be worn correctly to offer the most protection. It needs to cover both the nose and the mouth and fit snug enough to prevent gaps that would allow penetration by the respiratory droplets. Face coverings should not be worn for more than one day, and many users may benefit from changing their masks throughout the day.
