N95 Respirator Mask Types: Basic Information

The N95 is pretty popular series of particulate respirator masks that fulfill Usa government standards. The face masks are certified to greatly reduce contact with 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 arranged by oil compatibility and also filter efficiency.

The sales copy suggests the way the filter tests in environments exposed to oil aerosols:

N95, N99, & N100. These air filters are to not be utilized with oil aerosols. These have to be used in environments exposed to particulates which do not incorporate oil. In cases that are many, the n- respirators are reused several times.

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

P95, P99, & P100. These filters are oil proof. These respirators are usually used in any environment exposed to risky particulates. The p- respirators are governed by time of use limitations.

The filter efficiency number describes the portion of airborne particulates that have been eliminated in testing: 95 %, hundred %, in addition to ninety nine %. If a mask is NIOSH approved then it will have a stamp of approval class included on the respirator.

NIOSH approved masks also come in various sizes, as well as a well fitting mask is vitally important. When test fitting an N95 mask or any other particulate respirator mask, follow these quick steps:

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

2. Stretch and place the top headband on the rear of your head above the ears of yours. Stretch out the bottom headband over the head and location below your ears.


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

4. In order to test fit, cup both hands over the respirator and exhale vigorously. If air flows around your nose, secure the nosepiece: if air flows all around the edges of the respirator, reposition the headbands to fit much better as well as check once more until there is no air leakage.

Before selecting the ideal mask, it’s also advised that you speak with experienced industrial safety personnel about an assessment of your specific environment.
