N95 Respirator Mask Types: Primary Info
The N95 is the preferred series 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 courses, 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 will not be for use with oil aerosols. These needs to be used in environments uncovered to particulates which do not include oil. In many cases, the n- respirators might 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 strong or liquid hazard together with oil-based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any surroundings uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.
The filter efficiency number refers to the share of airborne particulates that have been removed in testing: ninety five%, ninety nine%, and a hundred%. If a mask is NIOSH approved then it will have a stamp of approval class printed on the respirator.
NIOSH approved masks additionally come in numerous sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, observe these easy steps:
