N95 Respirator Mask Types: Basic Information


The N95 is the most popular series of particulate respirator masks that meet U . s . government standards. The eye masks are tested to reduce experience airborne contaminates by NIOSH – the nation’s Institiute for Occupational Safety and Health. NIOSH has nine total approval classes, N95, N99, N100, R95, R99, R100, P95, P99, P100 organized by oil compatibility and filter efficiency.

The letter signifies how a filter tests in environments confronted with oil aerosols:

N95, N99, & N100. These filters are not to provide with oil aerosols. These must be used in environments confronted with particulates that do not contain oil. In many cases, the n- respirators might be reused several times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be used in atmospheres containing particulates any solid or liquid hazard including oil-based hazards. They’re one-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators works extremely well in any environment confronted with hazardous particulates. The p- respirators are be subject to period of use limitations.

The filter efficiency number means the amount of airborne particulates that have been removed in testing: 95%, 99%, and 100%. If the mask is NIOSH approved it have a stamp of approval class printed around the respirator.

NIOSH approved masks can be found in various sizes, and a well fitting mask is important. When test-fitting an N95 mask or any other particulate respirator mask, follow these simple actions:

1. Press the mask (respirator ) firmly contrary to the face with all the outside nosepiece about the bridge of one’s nose.

2. Stretch and set the top headband around the back of one’s head above your ears. Stretch underneath headband in the face mask head and position below your ears.

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

4. To check fit, cup the hands over the respirator and exhale vigorously. If air flows around onto your nose, tighten the nosepiece: if air flows round the edges of the respirator, reposition the headbands to match better and test again until there isn’t any air leakage.

Before selecting the best mask, it is usually suggested that you simply talk to experienced industrial safety personnel a good assessment of your respective particular environment.
