N95 Respirator Mask Types: Basic Information

N99 mask
The N95 is the most popular series of particulate respirator masks that meet U . s . government standards. The face masks are tested to cut back exposure to airborne contaminates by NIOSH - the country'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.

FFP3
The letter signifies what sort of filter tests in environments encountered with oil aerosols:

N95, N99, & N100. These filters aren't to be used with oil aerosols. These must be found in environments exposed to particulates which don't contain oil. In many cases, the n- respirators can 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 are one-time use masks.

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

The filter efficiency number refers back to the area of airborne particulates which are removed in testing: 95%, 99%, and 100%. If a mask is NIOSH approved this have a stamp of approval class printed on the respirator.

NIOSH approved masks are also available in different sizes, along with a well fitting mask is important. When test-fitting an N95 mask or any other particulate respirator mask, follow these simple steps:

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

2. Stretch and squeeze top headband around the back of your respective head above your ears. Stretch the lower headband on the head and position using your ears.

3. With hands, mold the metal nosepiece towards the type of your nose.

4. To evaluate fit, cup both of your hands over the respirator and exhale vigorously. If air flows around onto your nose, tighten the nosepiece: if air flows throughout the edges from the respirator, reposition the headbands to match better and test again until there's no air leakage.

Before choosing the best mask, additionally it is suggested that you speak with experienced industrial safety personnel about an assessment of one's particular environment.
