Buyer Information

RFQ Details

According to HHS (US Department of Health and Human Services) regulations, NIOSH (National Institute of Occupational Safety and Health) classifies its certified anti-particulate masks into 9 categories. The specific certification is operated by the NPPTL laboratory under NIOSH.
In the United States, masks can be classified into three grades-N, R, P according to the minimum filtering efficiency of the filter material.
N-type masks can only filter non-oily particles, such as: dust, acid mist, paint mist, microorganisms, etc. Most of the suspended particles in air pollution are non-oily.
R masks are only suitable for filtering oily particles and non-oily particles, but when used for oily particles, the use time must not exceed 8 hours.
Type P masks can filter both non-oily particles and oily particles. Oily particles such as: oil fume, oil mist, etc.
According to different filtration efficiency, there are differences of 90, 95, 100, which means that the minimum filtration efficiency is 90%, 95%, 99.97% under the test conditions specified in the standard.
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 a "N95 mask".
