What Type of Mask a Common man should use? what to do after using mask?

People around the world are using two types of masks to protect against the corona virus.

There is an N95 mask, also called FFP2. This mask provides two-way protection. It filters both the wearer's breathing and exhalation.
This mask filters out 94% of airborne particles, including other bacteria and viruses that are 0.3 microns in size. This mask prevents saliva droplets and respiratory infections from spreading.
Importantly, the World Health Organization recommends that these masks be worn only by medical personnel.

The second most commonly used mask is called a surgical mask. It should only be worn by people who are sick.
This mask does not allow the saliva of sick people or other moisture from the nose and mouth to reach healthy people.
Sometimes the mask is loose. If it is not worn properly, other substances or moisture contained in a sick person's breath may leak into the air from around the mask.
It should not be touched after wearing the mask as it can spread through the hands as well.

 Each mask should be changed after four to five hours and the used mask should be thrown in the trash.
Hands should be washed with soap or hand sanitizer after removing the mask.
