Can wearing a mask prevent infection?
Common masks include the following: ordinary cotton masks, disposable masks (such as medical surgical masks), and N95 masks.
Disposable masks (medical surgical masks)
It can prevent respiratory infections to a certain extent, but not haze.
The medical surgical mask has three layers, from the outside to the inside are the waterproof layer, the filter layer, and the comfort layer. The comfort layer is a layer of non-woven fabric. When wearing, the white non-woven fabric faces inward, the blue waterproof layer faces outward, and the side with the metal sheet faces up. Don't wear it. The rubber band hangs on both ears and pinches the metal sheet Fit the nose and smooth the cheeks so that there is no gap between the mask and the face.
When buying, you should choose a mask that clearly states "Medical surgical mask" on the outer packaging.
N95 mask
Can effectively prevent respiratory tract infections, can prevent haze.
The N95 mask is one of nine anti-particulate masks certified by NIOH (National Institute of Occupational Safety and Health). "N" means particles that are not suitable for oiliness (oil fumes produced by cooking are oily particles, and the droplets generated by people talking or coughing are not oily); "95" refers to filtering under the test conditions specified by the NIOSH standard The efficiency reaches 95%.
N95 is not a specific product name. As long as it meets the N95 standard and has passed the NIOSH review, it can be called "N95 mask".
The biggest feature of the N95 mask is that it can prevent droplet infections caused by patients' body fluids or blood splashes. The size of the droplets is 1 to 5 microns in diameter. The US Occupational Safety and Health Administration (OSHA) stipulates that for medical institutions, medical personnel exposed to tuberculosis bacteria must wear masks above the N95 standard.
Compared with medical surgical masks, N95 masks are better sealed. When choosing the N95 mask, try to choose the N95 mask without a breathing valve.
Ordinary cotton mask
Its material may be cotton, gauze, wool, canvas and velvet, etc. Because the material itself is not dense enough to prevent infection.
