Answer 2

N95 masks provide a higher degree of protection than a surgical mask or cloth mask because they can filter out both large and small particles when the wearer breathes.

They’re called N95 masks because they’re designed to block 95% of particles or liquids that may come in contact with your face. However, these masks are not for general public use and should be reserved for healthcare workers and other medical first responders. They’re also incompatible with children or people with facial hair. Healthcare providers are fit tested for these masks, and like surgical masks, they’re intended to be single-use only, though researchers are examining effective ways to clean these masks.
They help effectively to fight air-pollution and COVID-19.
