The N95 is the most well-liked number of particulate respirator masks that meet up with Usa federal government requirements. The encounter masks are tested to lower publicity to airborne contaminates by NIOSH - the Nationwide Institiute for Occupational Basic safety and Well being. NIOSH has nine overall approval classes, N95, N99, N100, n95 face mask for sale R95, R99, R100, P95, P99, P100 arranged by oil compatibility and filter performance.
The letter signifies how the filter checks in environments exposed to oil aerosols:
N95, N99, & N100. These filters are certainly not for use with oil aerosols. These really should be Utilized in environments exposed to particulates which do not include oil. In lots of situations, the n- respirators could be reused multiple instances.
R95, R99, & R100. These filters are oil resistant. The r- respirators may be used in atmospheres containing particulates any solid or liquid hazard including oil-primarily based hazards. They're a single-time use masks.
P95, P99, & P100. These filters are oil evidence. These respirators can be employed in almost any surroundings exposed to harmful particulates. The p- respirators are subject to time of use limits.
The filter effectiveness selection refers to The proportion of airborne particulates which were eradicated in screening: ninety five%, ninety nine%, and a hundred%. If a mask is NIOSH permitted then it could have a stamp of approval course printed to the respirator.
NIOSH authorized masks also arrive in numerous sizes, plus a well fitting mask is vitally critical. When check-fitting an N95 mask or other particulate respirator mask, observe these straightforward measures:
