N95 Respirator Mask Types: Basic Info

The N95 is the most popular 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 nine 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 exposed to grease aerosols:

N95, N99, & N100. These filters should not to be used with oil aerosols. These needs to be utilized 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 stable or liquid hazard together with oil-based mostly hazards. These are one-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any environment exposed to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter effectivity number refers to the share of airborne particulates that had been removed in testing: ninety five%, 99%, and one 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 several sizes, and a well fitting masks is vitally important. When test-fitting an N95 masks or different particulate respirator mask, observe these simple steps:
