The N95 is the most popular sequence of particulate respirator masks that meet United States authorities standards. The face masks are tested to reduce publicity to airborne contaminates by NIOSH – the National Institiute for Occupational Safety and Health. NIOSH has 9 total approval lessons, N95, N99, N100, R95, R99, R100, P95, P99, P100 organized by oil compatibility and filter efficiency.
The letter signifies how the filter tests in environments uncovered to grease aerosols:
N95, N99, & N100. These filters usually are not to be used with oil aerosols. These ought to be utilized in environments exposed to particulates which don’t include oil. In many cases, the n- respirators can be reused a number of times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres containing particulates any solid or liquid hazard together with oil-primarily based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be used in any setting exposed to hazardous particulates. The p- respirators are topic to time of use limitations.
The filter efficiency number refers to the share of airborne particulates that had been removed in testing: 95%, ninety nine%, and one hundred%. If a mask is NIOSH approved then it can have a stamp of approval class printed on the respirator.
NIOSH approved masks additionally come in different sizes, and a well fitting masks is vitally important. When test-fitting an N95 masks or other particulate respirator mask, comply with these straightforward steps:
