Bacterial Filtration Efficiency Face Mask Help Limit Germs Spread

Functions and USES

The filtration efficiency of N95 mask on particles with aerodynamic diameter of 0.075 m±0.02 m is more than 95%.The aerodynamic diameters of airborne bacterial and fungal spores vary mainly between 0.7 and 10 m and are also within the range of the N95 mask.Therefore, N95 mask can be used for the respiratory protection of certain particles, such as polishing, cleaning and processing of dust from mineral, flour and some other materials, etc., it is also suitable for the liquid or non-oily particles produced by spraying, which do not produce harmful volatile gases.It can effectively filter and purify the abnormal odors inhaled (except toxic gases), help to reduce the exposure level of some inhalable microbial particles (such as mold, anthrax bacillus, tuberculosis bacillus, etc.), but it does not eliminate the risk of contact infection, illness or death

The U.S. department of labor has recommended N95 masks for health care workers to protect against airborne infections such as influenza and tuberculosis.

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.

The N95 mask is one of nine NIOSH certified particle respirators.N95 is not a specific product name, but as long as the product meets the N95 standard and passes the NIOSH review, it can be called N95 mask, which can achieve filtration efficiency of more than 95% on particles with an aerodynamic diameter of 0.075 m±0.020 m.
