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 exposed to grease aerosols:

N95, N99, & N100. These filters usually are not to be used with oil aerosols. These should be utilized in environments uncovered to particulates which don't comprise oil. In many cases, the n- respirators can be reused multiple times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be used in atmospheres containing particulates any stable or liquid hazard including oil-based hazards. These are one-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators can be used in any surroundings uncovered to hazardous particulates. The p- respirators are topic to time of use limitations.

The filter effectivity number refers to the proportion of airborne particulates that had been removed in testing: ninety five%, ninety nine%, and a hundred%. If a masks 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 different particulate respirator masks, follow these easy steps:
