N95 Respirator Mask Types: Primary Data

The N95 is the most popular 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 9 total approval lessons, 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 uncovered to grease aerosols:

N95, N99, & N100. These filters usually are not for use with oil aerosols. These needs to be used in environments uncovered to particulates which do not include 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 together with oil-primarily based hazards. These are one-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators can be used in any atmosphere exposed to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter efficiency number refers back to the share of airborne particulates that have been 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 additionally come in numerous sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator mask, follow 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 beneath your ears.

3. With each palms, mold the metal nosepiece to the shape of your nose.

4. To test fit, cup each palms over the respirator and exhale vigorously. If air flows around your nose, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit higher and test once more until there is no such thing as a air leakage.

Earlier than selecting the best mask, it is also prompt that you simply speak with skilled industrial safety personnel about an evaluation of your particular environment.
