What are the differences between N95 masks and other face masks?
As the stock of N95 masks is critically low, residents are urged to sew face masks at home for medical community and family's protection. Then, can handmade masks be a effective way at protecting you from the coronavirus and what are the differences between N95 masks and other face masks?
As is known that coronavirus can linger in the air for up to 30 minutes and it can be transmitted from person to person through vapor (breath), coughing, sneezing, saliva and transfer over commonly touched objects. Compared with other types of surgical masks and face masks, N95 masks can create a tight seal between the respirator and your face, which helps filter at least 95% of airborne particulates.
Because of the tight seal and the strong barrier between your nose and mouth and the outside world, moisture increases inside the mask. The solve this problem, some N95 masks have an exhalation valve to make it easier to breathe and also help keep the face cooler while wearing them. In US health care settings, N95 masks must go through a mandatory fit test using a protocol set by OSHA, the Occupational Safety and Health Administration, before use.
Each model of N95 mask from each manufacturer is also certified by the National Institute for Occupational Safety and Health. N95 surgical respirator masks go through a secondary clearance by the Food and Drug Administration for use in surgery for better protecting practitioners from exposure to substances such as patient blood.
