N95 Respirator Mask Types: Basic Data

The N95 is the most well-liked collection of particulate respirator masks that meet United States government 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 classes, 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 are not for use with oil aerosols. These must be used in environments uncovered to particulates which don’t include oil. In lots of cases, the n- respirators may 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 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 subject to time of use limitations.

The filter efficiency number refers back to the proportion of airborne particulates that had been removed in testing: ninety five%, 99%, and a hundred%. If a mask is NIOSH approved then it is going to have a stamp of approval class printed on the respirator.

NIOSH approved masks additionally come in several sizes, and a well fitting masks is vitally important. When test-fitting an N95 masks or different particulate respirator mask, comply with these straightforward steps:
