What is an N95 mask? What if I can't buy an N95 mask? How do I wear it? How long should I wear it at a time to replace it?
N95 is not a specific product name but a standard. KN95 masks are the Chinese standard.The filtering efficiency of the mask filter material for non-oil particles (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%.
Since the diameter of coronavirus pneumonia (SARS) virus is about 0.1 to 0.12 microns, wearing N95 or KN95 masks is a feasible prevention method.

What if I can't buy N95 or medical-surgical masks?
How to wear it?
Why must we distinguish between outside and inside? Because the outside of the mask is mainly the water barrier layer, which can prevent foreign matter droplets and liquid splashes, while the inside is primarily the moisture absorption layer, which can absorb the water vapor generated when we breathe and speak, it will be more comfortable to wear.
If you wear the opposite, think about it, absorbing the other splashes of water droplets on the mask. Is it just right?
2. Distinguish between the upper face and the mask's lower face. After figuring out the outer surface and the inner surface, it is easier to distinguish the upper body from the lower surface. Remember, the side with the soft metal strip is always on the top.
3. How to wear? Please wash your hands before putting on the mask! The wearing method of medical protective covers is significant; otherwise, even if you buy the right show, wearing it improperly will affect the filtration effect.
Specific wearing steps are as follows:
2. Cover the nose, mouth, and chin with the protective mask, with the nose clip up close to the face.
3. pulling down the tether strap with the other hand through the top of the head and placing it behind the neck under the ear.
4. pull the upper ligature to the middle of the head.
5. Place the fingertips of both hands on the metal nose clip and press the clip inward with your fingers from the middle position, moving the pressure to the sides respectively, so that the clip is shaped according to the bridge of the nose.

How long can a mask be worn at a time?
N95 masks protect very well, but there is a noticeable stuffy feeling after wearing them for a long time. Wang Yuan, professor of immunology at Peking University School of Basic Medicine, reminds me that N95 masks should not be worn for more than 4 hours at a time. If the N95 cover is used continuously for a long time, it will cause lung damage and may cause problems such as emphysema.Maysino is a supplier of KN95 masks and medical masks in China. maysino's KN95 protective covers are exported to more than 40 countries and regions, including the United States, Europe, Japan, Southeast Asia, the Middle East, South America, and Australia, with excellent quality and competitive prices.
