N95 medical protective mask is one of 9 NIOSH certified particulate protection masks. "N" means not resistant to oil. "95" means that the concentration of particles in the mask is more than lower than that of particles outside the mask when exposed to a specified number of special test particles. Of these, are not averages, but MINIMA. N95 is not a specific product name, as long as it meets the N95 standard and passes the NIOSH review, it can be called "N95 mask" . N95 protection level means that under the testing conditions stipulated by NIOSH standard, the filtering efficiency of mask filter material to non-oily particles (such as dust, acid fog, paint fog, microorganism, etc.) reaches .

Functions and Uses

The N95 medical respirator has a filtration efficiency of more than for particles with a diameter of 0.075 M to 0.02 m aerodynamics. The aerodynamics diameters of airborne bacteria and fungal spores varied between 0.7 m and 10 m, and were within the protective range of the N95 mask. Therefore, the N95 respirator can be used for inhalation protection of certain particulate matter, such as dust from grinding, cleaning and handling of minerals, flour and certain other materials, it is also suitable for liquid or non-oily particles produced as a result of spraying, which do not produce harmful volatile gases. Effective in filtering and purifying inhaled odors (except toxic gases) to help reduce exposure to certain respirable microbial particles such as mold, bacillus anthracis, mycobacterium tuberculosis, etc. , however, it does not eliminate the risk of contact infection, illness or death.

The United States Department of Labor has recommended that health care workers use N95 masks to protect against airborne infections such as influenza and tuberculosis.
