China N95 Respirator made in China is one of the 9 kinds of particulate protection masks certified by NIOSH. "N" means not resistant to oil. "95" means that when exposed to a specified number of special test particles, the particle concentration in the mask is more than 95% lower than the particle concentration outside the mask. The 95% value is not the average value, but the minimum value. N95 is not a specific product name, as long as it meets the N95 standard, and products that pass the NIOSH review can be called "N95 respirator." The protection grade of N95 means that under the test conditions specified by the NIOSH standard, the filtering efficiency of the mask filter material to non-oily particulate matter (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%.
The N95 respirator Factory has a filtration efficiency of more than 95% for particles with an aerodynamic diameter of 0.075µm±0.02µm. The aerodynamic diameter of airborne bacteria and fungal spores mainly varies between 0.7-10µm, which is also within the protection range of N95respirator. Therefore, the N95 respirator can be used for the respiratory protection of certain particulate matter, such as the dust generated by the processes of grinding, cleaning and processing minerals, flour and certain other materials. It is also suitable for the liquid or non-oily generated by spray particulate matter of harmful volatile gas. It can effectively filter and purify the inhaled abnormal odors (except toxic gases), help reduce the exposure level of certain inhalable microbial particulates (such as mold, anthrax, tuberculosis, etc.), but it cannot eliminate contact infection, illness or risks of death.
In addition to the filtration efficiency of CE N95 respirator, the adhesion between the mask and the face is one of the important factors that determine the effectiveness of the mask. Different types of respirators have a big difference from the suitability of the human face. Therefore, before using the respirator, the suitability of the mask should be checked first. After the wearer's face tightness test, ensure that the air can enter and exit through the respirator when it is close to the edge of the face.
