How to Use a Face Mask Correctly
Knowledge point one
What are the common types of masks?
Disposable masks (medical surgical masks)
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. 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 type mask
N95 mask is one of 9 anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health). "N" means not suitable for oily particles (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 in the NIOSH The efficiency reaches 95%.
N95 is not a specific product name. As long as it conforms to the N95 standard and has passed the NIOSH review, the product can be called "N95 mask".
The biggest feature of the N95 mask is that it can prevent the spread of droplets caused by patients' body fluids or blood splashes. The size of the droplets is 1 to 5 microns in diameter. The United States 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 an N95 mask, try to choose an N95 mask without a breathing valve.
