N95 Respirator Mask Types: Primary Data

The N95 is the preferred 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 classes, 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 are usually not for use with oil aerosols. These should be utilized in environments uncovered to particulates which do not contain oil. In many cases, the n- respirators might 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 stable 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 setting uncovered to hazardous particulates. The p- respirators are topic to time of use limitations.

The filter efficiency number refers to the percentage of airborne particulates that have been removed in testing: ninety five%, ninety nine%, 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 also come in several sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, follow these easy 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 bottom headband over the head and position below your ears.

3. With each fingers, mold the metal nosepiece to the shape 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 higher and test again until there isn’t any air leakage.

Earlier than selecting the best mask, it can also be suggested that you speak with experienced industrial safety personnel about an evaluation of your particular environment.
