Are there face masks that should not be worn during the COVID-19 pandemic?

See full answerFace 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.

How should I properly put on face masks during the COVID-19 pandemic?

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.

Does WHO recommend the use of masks with exhalation valves to prevent transmission of COVID-19?

No, WHO does not advise using masks or respirators with exhalation valves. These masks are intended for industrial workers to prevent dust and particles from being breathed in as the valve closes on inhale. However, the valve opens on exhale, making it easier to breathe but also allowing any virus to pass through the valve opening. This makes the mask ineffective at preventing the spread of COVID-19 or any other respiratory virus.

What are the materials for making masks for the coronavirus disease?

Fabric masks should be made of three layers of fabric:

• Inner layer of absorbent material, such as cotton.
• Middle layer of non-woven non-absorbent material, such as polypropylene.
• Outer layer of non-absorbent material, such as polyester or polyester blend.
