Product Description

"N" means not oil resistant, "95" means that when exposed to a specified number of special test particles, the concentration of particles inside the mask is more than 95% lower than that outside the mask. The protection level is N95, which means the filtering efficiency of the mask filter material for non-oily particles (such as dust, acid mist, paint mist, microorganisms, etc.). ) It reaches 95% under the test conditions stipulated by the NIOSH standard. N95 mask is one of the nine particulate protective masks certified by NIOSH.
Generally speaking, the protective effect of N95 masks and KN95 masks are the same. The difference is that KN meets Chinese standards and N meets American standards.
In China, KN95 means that the filtration efficiency of non-oily particles with a diameter of 0.3μm is greater than 95%. However, NIOSH standard N95 has a 95% success rate for particles with a diameter of 0.075 microns.
Since the diameter of the pneumonia (SARS) virus is about 0.1 to 0.12 microns, wearing an N95 or KN95 mask is a viable preventive method.
In addition, medical surgical masks can also be used to prevent infectious diseases. Medical surgical masks can block 70% of bacteria, N95 masks can block 95% of bacteria, and the latter has a stronger blocking effect.
Paper masks, activated carbon masks, cotton masks, and sponge masks he limited effectiveness in preventing infection due to their tighter materials.
For the purpose of self-protection and reducing the risk of respiratory infections, the latter two masks (medical surgical masks and N95 masks) can be worn.
If you go to a generally open public place, do not he close contact with respiratory patients, wear a medical surgical mask, and no excessive protection is enough. However, if you come into contact with patients with suspected respiratory infections, you need to wear anti-biological N95 masks for effective protection.
