High Breathability KN95 Face Mask Dust Prevention Environmental Friendly

Other NIOSH certified respirators include N95, N99, N100, R95, R99, R100, P95, P99, and P100.These levels of protection can cover the protection range of N95.

"N" stands for not resistant to oil, suitable for non-oily particles.

"R" stands for oil resistant to oil, suitable for oily or non-oily particles. If used for protection of oily particles, the use time should not exceed 8 hours.

"P" stands for oil proof, suitable for oily or non-oily particles, if used for oily particles, the use time should follow the manufacturer's recommendations.

"95", "99" and "100" refer to the filtration efficiency level when tested with 0.3 micron particles."95" means the filtration efficiency is above 95%, "99" means the filtration efficiency is above 99%, and "100" means the filtration efficiency is above 99.7%.

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.
