What kind of mask should be used during the COVID-19 pandemic?
Masks and respirators can provide varying degrees of protection, with well-fitting NIOSH-approved respirators (e.g., N95s) offering the most protection.

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.
