In addition to the filtration efficiency of the mask, the tightness between the mask and the face is one of the important factors determining the effectiveness of the mask.Therefore, the suitability of the mask should be tested before use.When testing the tightness of the wearer's face, ensure that air can pass in and out of the mask under the condition of close fitting to the edge of the face
The N95 mask is one of nine NIOSH certified particle respirators."N" means oil intolerance."95" means that the concentration of particles in the mask is more than 95% lower than the concentration of particles outside the mask when exposed to a specified number of specialized test particles.95% of these values are not averages, but minimums.The N95 is not a specific product name, as long as it meets the N95 standard and is approved by NIOSH.The protection grade of N95 means that the filtration efficiency of mask filter material on non-oily particulate matter (such as dust, acid mist, paint mist, microorganism, etc.) is 95% under the testing conditions stipulated by NIOSH standard.
