Can n95 masks prevent dust?

  • The N95 mask is one of 9 types of particulate protective 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 inside the mask is more than 95% lower than the particle concentration outside the mask. The value of 95% is not an average value, but a minimum value.

    N95 is not a specific product name, as long as the product meets the N95 standard and passes the NIOSH review, it can be called "N95 mask". The protection level of N95 means that under the testing conditions specified by the NIOSH standard, the filtering efficiency of the mask filter material for non-oily particles (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%.

    Precautions for wearing n95 masks:
    Before wearing, check whether the n95n95 mask has expired and whether the outer packaging of the n95n95 mask is damaged. The damaged n95 mask has been infected by external bacteria and has lost its protective effect. Do not wear it with luck.

    Before wearing the n95n95 mask, you should take soap, soap and other cleaning utensils with sterilization and antivirus effect, and wash your hands first. If you really do not have the conditions to wash your hands, you should also avoid touching the inside of the n95 mask with your hands during the process of wearing the n95 mask, so as to prevent the bacteria on your hands from spreading to the n95 mask.

    N95 masks must be purchased with qualified products that have passed the N95 mask testing equipment, otherwise safety problems are prone to occur!
