There are three layers of medical disposable masks, from the outside to the inside are the waterproof layer, the filter layer, and the comfort layer. The comfort layer is a layer of gauze. When worn, the white gauze faces inward, and the blue waterproof layer faces outwards, with a metal sheet on the side. Face up, don’t wear it backwards, put the rubber band on your ears and squeeze the metal piece to fit your nose, smooth your cheeks, so that there is no gap between the mask and your face.
N95 masks are generally composed of a multi-layer structure, which are non-woven layer, anti-adhesive layer, melt blown layer, and filter layer. The most important thing in the N95 mask is the barrier layer (that is, the filter layer) or the meltblown layer. The fiber diameter of the meltblown layer is relatively small, about 2 microns (μm), so it is only one-tenth of the diameter of the spunbond layer. Bacteria and blood penetrate its vital role. If there are too many meltblown layers, it will be more difficult to breathe. Adding a barrier layer of ES hot air cotton to the N95 mask is just breathable and has a filling effect. Therefore, the barrier layer is a way to reduce the problem of breathing difficulties while also allowing the N95 mask to filter The effect is better.
The N95 mask is one of the nine particulate protective masks certified by NIOSH. It can filter particles with a physical diameter of 0.075µm±0.020µm in the air with a filtration efficiency of more than 95%.
Medical surgical masks are generally made of non-woven materials. Through filtering to play a role in isolation, which can prevent the spread of influenza and respiratory diseases.
The N95 mask is used for the respiratory protection of certain particulate matter, such as dust generated during the process of grinding, cleaning and processing minerals, flour and certain other materials. It is also suitable for liquid or non-oily substances produced by spraying and does not cause harmfulness. Volatile gas particles are recommended to be used by medical staff during the new crown period.
Medical surgical masks are mainly used in high-demand medical environments such as medical outpatient clinics, laboratories, and surgery, with relatively high safety factors and strong resistance to bacteria and viruses.

Medical disposable masks can block 70% of bacteria, and N95 masks can block 95% of bacteria. If you are going to public places and not in contact with patients, it is sufficient to wear medical disposable masks without excessive protection, but if you visit or contact patients, Wear an anti-biological N95 mask.
