Medical Grade KN95 Face Mask With CE Certification Good Air
Permeability
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.
