What is the N95 mask that everyone seeks?

Faced with the epidemic of this type of coronavirus pneumonia, “N95 mask” has become a sensitive word that affects social nerves. Masks are being robbed everywhere, and n95 mask suppliers are working overtime to produce them.

Jiande Chaomei Daily Chemicals Co., Ltd. was founded in 1990, formerly known as Chaomei Industrial Company of Chinese Academy of Sciences. It is an advanced kn95 mask supplier in China

N95 is not a specific product name, but a standard. Products reviewed by the National Institute of Occupational Safety and Health (NIOSH) can be called “N95 masks.”

“N” means not resistant to oil, “95″ means that under the specified number of special test particles, the particle concentration inside the mask is more than 95% lower than the particle concentration outside the mask. The protection level of N95 means that under the testing conditions specified in the NIOSH standard, the filtering efficiency of the mask filter material to non-oily particles (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%. The N95 mask is one of the nine particulate protective masks certified by NIOSH.

Generally speaking, N95 masks and KN95 masks have the same protective effect. The difference is that KN meets Chinese standards and N meets American standards.

In China, KN95 means that the filtration efficiency for non-oily particles above 0.075 microns is greater than 95%. In the NIOSH standard, N95 has a 95% blocking success rate for particles with a diameter of 0.075 microns.

Since the diameter of the coronavirus pneumonia (SARS) virus is about 0.1 to 0.12 microns, it is necessary to wholesale surgical masks for feasible prevention.

In addition, wholesale medical surgical masks can block 70% of bacteria, while N95 masks can block 95% of bacteria and have a stronger shielding effect.

Paper masks, activated carbon masks, cotton masks and sponge masks are not compact enough to prevent infection.
