The face masks are tested to reduce exposure 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 oil aerosols:

N95, N99, & N100. These filters aren’t to be used with oil aerosols. These should be used in environments uncovered to particulates which do not comprise 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 used in atmospheres containing particulates any solid or liquid hazard together with oil-primarily 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 effectivity number refers to the share of airborne particulates that have been removed in testing: ninety five%, ninety nine%, and one hundred%. If a mask is NIOSH approved then it would have a stamp of approval class printed on the respirator.

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