The N95 is the preferred series of particulate respirator masks that meet up with United States government specifications. The deal with masks are analyzed to scale back publicity to airborne contaminates by NIOSH - the National Institiute for Occupational Basic safety and Health and fitness. NIOSH has 9 whole acceptance courses, N95, N99, N100, R95, R99, R100, P95, P99, P100 structured by oil compatibility and filter effectiveness.
The letter signifies how the filter assessments in environments subjected to oil aerosols:
N95, N99, & N100. These filters are usually not to be used with oil aerosols. These must be used in environments exposed to particulates which tend not to have oil. In many situations, the n- respirators is usually reused several situations.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres made up of particulates any sound or liquid hazard together with oil-based mostly dangers. These are definitely 1-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators may be used in any atmosphere subjected to hazardous particulates. The p- respirators are subject matter to time of use limitations.
The filter effectiveness amount refers to The share of airborne particulates that were taken off in testing: ninety five%, 99%, and a hundred%. If a mask is NIOSH permitted then it could have a stamp of acceptance class printed within the respirator.
NIOSH approved masks also come in various dimensions, plus a very well fitting mask is vitally important. When exam-fitting an N95 masks n95 for sale mask or other particulate respirator mask, abide by these easy measures:
