N95 Respirator Mask Types: Primary Info
The N95 is the preferred series of particulate respirator masks that meet United States government 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 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 oil aerosols:
N95, N99, & N100. These filters are not for use with oil aerosols. These should be utilized in environments exposed to particulates which don't comprise oil. In many cases, the n- respirators will be reused a number of times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres containing particulates any strong or liquid hazard including oil-based mostly hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be used in any environment uncovered to hazardous particulates. The p- respirators are topic to time of use limitations.
The filter effectivity number refers back to the proportion of airborne particulates that were removed in testing: 95%, 99%, and 100%. 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 mask or different particulate respirator mask, comply with these easy steps:
1. Press the mask (respirator ) firmly in opposition to 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 position below your ears.
3. With both fingers, mold the metal nosepiece to the shape of your nose.
4. To test fit, cup both hands over the respirator and exhale vigorously. If air flows round your nose, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to fit better and test again till there isn't any air leakage.
Before choosing the right mask, it is also instructed that you speak with skilled industrial safety personnel about an evaluation of your particular environment. Website URL:
