N95 respirator masks
Disposable masks and KN95 masks are sold in batches, all of which are high-quality products that meet the customs export requirements and are fully qualified.
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.
N95 respirator masks fit tightly around your face. They filter out 95% or more of the smallest particles in the air. But they have to fit just right in order to work. 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. And they can't block the tiniest particles that may carry coronavirus.
