What should I pay attention to when wearing KN95 mask

KN95 is a respirator certified by the national GB2626-2006 respiratory protection user self-suction filter respirator standard. It has the same protection level as N95, but it follows the test standards of different countries. Here's a look at what level KN95 masks can do.

 

What is KN95 level mask for

 

The filtration efficiency of KN95 grade masks is above 95% for particles with aerodynamic diameter ≥0.3 m. The aerodynamic diameters of airborne bacteria and fungal spores varied mainly between 0.7 and 10 m, and were also within their protective range.

 

Therefore, this mask can be used for respiratory protection of certain particulate matter, such as dust produced by grinding, cleaning and treating minerals, flour and some other materials, and also for liquid or non-oily particulate matter produced by spraying that does not produce harmful volatile gases.

 

It effectively filters and purifies the odors inhaled (except for toxic gases) and helps reduce exposure to certain inhalable microbiological particles such as mold, Bacillus anthracis, bacillus tuberculosis, etc., but does not eliminate the risk of contact infection, illness, or death.

 

KN95 Precautions for wearing masks

 

1. Wash your hands before wearing the mask, or avoid touching the inside side of the mask with your hands while wearing the mask to reduce the possibility of contamination.

 

2. Distinguish the inside and outside, the top and bottom of the mask; KN95 masks have a printed side for the outside; One end of the metal/sponge strip is above the mask.

 

3. Do not squeeze the mask with your hands, including The N95 mask, which can only isolate the virus on the surface of the mask. If you squeeze the mask with your hands, the virus will be drenched with droplets, and you still have the chance to catch the virus.

 

4. Make sure the mask fits well with the face as much as possible. The simple test is: after wearing the mask, exhale forcefully, so that the air does not leak through the edge of the mask.
