What is the proper way to wear a mask to help prevent COVID-19?
• Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time. • Make sure it covers both your nose, mouth and chin. • When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask, or dispose of a medical mask in a trash bin. • Don’t use masks with valves.
Are there face masks that should not be worn during the COVID-19 pandemic?
Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. A face covering without vents or holes will also filter out particles containing the virus from inhaled and exhaled air, reducing the chances of infection. But, if the mask include an exhalation valve, a wearer that is infected (maybe without having noticed that, and asymptomatic) would transmit the virus outwards through it, despite any certification they can have. So the masks with exhalation valve are not for the infected wearers, and are not reliable to stop the pandemic in a large scale. Many countries and local jurisdictions encourage or mandate the use of face masks or cloth face coverings by members of the public to limit the spread of the virus.

Can I wear masks with exhalations valves during COVID-19?
