Why You Need a Mask
COVID-19 spreads primarily from person to person. This can be via droplets released when people sick with the new coronavirus cough or sneeze. It can also spread when you’re in close contact with someone who’s sick – e.g. when you hug or shake hands. Use the masks to help prevent the spread.
Filter Dust and
Bacteria in the Air.
It may also spread through airborne transmission, when tiny droplets remain in the air even after the person with the virus leaves the area. The KN95 will filter those droplets out.
