Can a respiratory face mask
stop the corona virus?
Yes, respiratory face masks (they fit tightly around your nose and mouth) , commonly know as N95 face masks can protect against the virus if you wear and use them correctly. You need to fit them correctly so they are tight to face.

What is KF94 respiratory?
The N95 is the USA Code, KN95 is China code, KF94 is Korea code and FFP2 is the EU code.
When do I need NF95 respiratory?
The role of facemasks is for patient source control, to prevent contamination of the surrounding area when a person coughs or sneezes. Patients with confirmed or suspected COVID-19 should wear a facemask until they are isolated in a hospital or at home. The patient does not need to wear a facemask while isolated.
My respirator has an exhalation valve, is that okay?
An N95 respirator with an exhalation valve does provide the same level of protection to the wearer as one that does not have a valve. The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale). Some users feel that a respirator with an exhalation valve keeps the face cooler and reduces moisture build up inside the facepiece. However, respirators with exhalation valves should not be used in situations where a sterile field must be maintained (e.g., during an invasive procedure in an operating or procedure room) because the exhalation valve allows unfiltered exhaled air to escape into the sterile field.
KF94 masks from Korea are the same to N95 masks in the USA.
