The N95 is the preferred series of particulate respirator masks that meet up with United States federal government benchmarks. The face masks are tested to scale back exposure to airborne contaminates by NIOSH - the Countrywide Institiute for Occupational Protection and Health. NIOSH has nine whole acceptance lessons, N95, N99, N100, R95, R99, R100, P95, P99, P100 structured by oil compatibility and filter performance.

The letter signifies how the filter tests in environments exposed to oil aerosols:

N95, N99, & N100. These filters usually are not to be used with oil aerosols. These must be Employed in environments subjected to particulates which never contain oil. In many instances, the n- respirators is often reused various occasions.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres that contains particulates any stable or liquid hazard together with oil-centered dangers. These are 1-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 to the percentage of airborne particulates which were eradicated in tests: ninety five%, ninety nine%, and one hundred%. If a mask is NIOSH accredited then it could have kn95 masks a stamp of acceptance class printed within the respirator.
