The N95 is the most popular series of particulate respirator masks that meet up with America govt specifications. The experience masks are examined to cut back publicity to airborne contaminates by NIOSH - the National Institiute for Occupational Protection and Wellness. NIOSH has nine total acceptance lessons, N95, N99, N100, R95, R99, R100, P95, P99, P100 arranged by oil compatibility and filter performance.
The letter signifies how the filter assessments in environments subjected to oil aerosols:
N95, N99, & N100. These filters are certainly not for use with oil aerosols. These needs to be used in environments exposed to particulates which will not have oil. In several situations, the n- respirators could be reused a number of times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be employed in atmospheres made up of particulates any solid or liquid hazard which include oil-primarily based dangers. These are definitely a single-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators may be used in almost any n95 mask surroundings exposed to hazardous particulates. The p- respirators are matter to time of use limitations.
The filter effectiveness variety refers to the percentage of airborne particulates that were eliminated in tests: 95%, ninety nine%, and 100%. If a mask is NIOSH accredited then it can have a stamp of acceptance class printed to the respirator.
NIOSH accredited masks also come in several dimensions, and also a nicely fitting mask is vitally important. When exam-fitting an N95 mask or other particulate respirator mask, comply with these quick steps:
