N95 Respirator Mask Varieties: Primary Information and facts

The N95 is the most well-liked number of particulate respirator masks that meet U . s . government specifications. The encounter masks are analyzed to cut back publicity to airborne contaminates by NIOSH - the Countrywide Institiute for Occupational Safety and Health. NIOSH has 9 whole acceptance courses, N95, N99, N100, R95, R99, R100, P95, P99, P100 organized by oil compatibility and filter performance.

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

N95, N99, & N100. These filters are certainly not for use with oil aerosols. These need to be Employed in environments exposed to particulates which don't consist of oil. In many cases, the n- respirators is usually reused numerous occasions.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be employed in atmospheres that contains particulates any strong or liquid hazard like oil-primarily based hazards. They are a person-time use n95 mask masks.

P95, P99, & P100. These filters are oil proof. These respirators can be utilized in almost any setting subjected to harmful particulates. The p- respirators are subject matter to time of use limitations.

The filter performance amount refers to the percentage of airborne particulates which were eliminated in tests: ninety five%, 99%, and 100%. If a mask is NIOSH approved then it will likely have a stamp of approval class printed about the respirator.

NIOSH authorized masks also appear in several sizes, along with a well fitting mask is vitally essential. When test-fitting an N95 mask or other particulate respirator mask, follow these quick techniques:
