May 3, 2020 business

The N95 is the preferred series of particulate respirator masks that meet United States government standards. The face masks are tested to reduce exposure 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 exposed to oil aerosols:

N95, N99, & N100. These filters usually are not to be used with oil aerosols. These should be used in environments uncovered to particulates which do not contain oil. In many cases, the n- respirators can 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 solid 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 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 percentage of airborne particulates that were removed in testing: ninety five%, 99%, and one hundred%. If a mask is NIOSH approved then it’s 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 mask or other particulate respirator mask, comply with these easy steps:
