N95 Respirator Masks Types: Basic Data

The N95 is the most popular series of particulate respirator masks that meet United States authorities 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 uncovered to oil aerosols:

N95, N99, & N100. These filters are usually not to be used with oil aerosols. These ought to be utilized in environments exposed to particulates which don’t include oil. In many cases, the n- respirators might be reused multiple times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres containing particulates any strong 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 used in any surroundings uncovered 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: 95%, 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 several sizes, and a well fitting mask is vitally important. When test-fitting an N95 masks or different particulate respirator masks, comply with these straightforward steps:

1. Press the masks (respirator ) firmly in opposition to the face with the outside nosepiece on the bridge of your nose.

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

3. With each arms, 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 around the edges of the respirator, reposition the headbands to fit better and test once more till there isn’t a air leakage.

Earlier than choosing the right mask, it is usually advised that you just speak with skilled industrial safety personnel about an evaluation of your particular environment.
