3 layer medical/surgical face mask
The CDC (Centers for Disease Control) recommends that everyone — sick or healthy — wear a face mask in places where it can be hard to stay 6 feet away from others, like grocery stores. That’s because studies show that people can spread coronavirus even if they don’t have symptoms (called asymptomatic) or before they have symptoms (called presymptomatic).
How the face mask works: A face mask covers your mouth and nose;
1). It can block the release of virus-filled droplets into the air when you cough or sneeze. This helps slow the spread of COVID-19.
2) When someone who has COVID-19 coughs, sneezes, or talks, they send tiny droplets with the coronavirus into the air. A face mask can filter out 80%/95% or more of the the smallest particles in the air.
Types of marks:
N95 respirator masks fit tightly around your face. They filter out 95% or more of the smallest particles in the air. N95 respirators and surgical masks should be reserved for health care workers and first responders. Because there aren’t enough of these masks for everyone, it’s important that they go to the doctors, nurses, and other medical staff who need them most.
KN95 dust protective masks: fit tightly around your face. They filter out 95% or more of the smallest particles in the air.
Surgical masks are often blue with white borders. They fit loosely across your nose and mouth. These masks shield against the large droplets that come from a sick person’s cough or sneeze, but they’re too loose to protect against all germs. So they can block 80% of the droplets in air.
