N95 Respirator Mask Types: Basic Info

The N95 is the preferred 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 nine 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 exposed to grease aerosols:

N95, N99, & N100. These filters will not be for use with oil aerosols. These must 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-based mostly hazards. These are one-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any setting 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%, 99%, and a hundred%. If a masks is NIOSH approved then it would have a stamp of approval class printed on the respirator.

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

1. Press the masks (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 place below your ears.

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

4. To test fit, cup both hands over the respirator and exhale vigorously. If air flows around your nostril, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit better and test once more until there is no air leakage.

Before selecting the best masks, it is usually advised that you converse with skilled industrial safety personnel about an evaluation of your explicit environment.
