Respirator Mask：
NIOSH N95 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.Can effectively filter and purify the inhalation of abnormal odor (except toxic gas), help reduce some microbial particles.
