N95 Respirator Mask Types: Basic Data

The N95 is the most popular series 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 courses, 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 usually are not for use with oil aerosols. These needs to be utilized in environments exposed 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 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 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: ninety five%, ninety nine%, and a hundred%. If a mask is NIOSH approved then it will 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 mask or other particulate respirator mask, observe these simple steps:

1. Press the mask (respirator ) firmly against the face with the outside nosepiece on the bridge of your nose.

2. Stretch and position the top headband on the back of your head above your ears. Stretch the underside headband over the head and position beneath your ears.

3. With both palms, mold the metal nosepiece to the form of your nose.

4. To test fit, cup both palms over the respirator and exhale vigorously. If air flows round your nose, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to fit better and test once more until there is no such thing as a air leakage.

Before selecting the best mask, it can also be instructed that you speak with experienced industrial safety personnel about an assessment of your particular environment.
