N95 Respirator Masks Types: Fundamental Info

The N95 is the most well-liked 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 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 oil aerosols:

N95, N99, & N100. These filters are usually not to be used with oil aerosols. These must be used in environments uncovered to particulates which do not comprise oil. In many cases, the n- respirators could be reused multiple times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be used 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 exposed to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter effectivity number refers to the percentage of airborne particulates that had been removed in testing: 95%, ninety nine%, and a hundred%. If a masks is NIOSH approved then it'll have a stamp of approval class printed on the respirator.

NIOSH approved masks also come in several sizes, and a well fitting masks is vitally important. When test-fitting an N95 mask or other particulate respirator masks, follow these simple steps:
