N95 Respirator Mask Varieties: Primary Information and facts

The N95 is the most popular series of particulate respirator masks that meet U.s. government specifications. The facial area masks are analyzed to reduce publicity to airborne contaminates by NIOSH - the National Institiute for Occupational Security and Wellness. NIOSH has nine full approval courses, N95, N99, N100, R95, R99, R100, P95, P99, P100 arranged by oil compatibility and filter effectiveness.

The letter signifies how the filter checks in environments subjected to oil aerosols:

N95, N99, & N100. These filters aren't for use with oil aerosols. These must be used in environments exposed to particulates which usually do not consist of oil. In many scenarios, the n- respirators could be reused multiple moments.

R95, R99, & R100. n95 mask These filters are oil resistant. The r- respirators may be used in atmospheres made up of particulates any sound or liquid hazard which include oil-primarily based dangers. These are typically 1-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators can be employed in any natural environment subjected to dangerous particulates. The p- respirators are issue to time of use restrictions.

The filter effectiveness range refers to The share of airborne particulates which were eradicated in testing: ninety five%, 99%, and one hundred%. If a mask is NIOSH accredited then it will likely have a stamp of acceptance class printed to the respirator.

NIOSH accepted masks also arrive in different dimensions, and also a effectively fitting mask is vitally crucial. When check-fitting an N95 mask or other particulate respirator mask, follow these effortless techniques:
