The N95 mask has become the most widely used series of particulate respirator masks which match with United States government standards. 

These face masks are tested to decrease the exposure of airborne infections by NIOSH – the National Institute for Occupational Safety and Health. If you are looking for an N95 face mask then you can visit at https://www.u-mask.eu/n95-masks.

NIOSH contains nine approved types, N95, N99, N100, R95, R99, R100, P95, P99, P100 coordinated by filter efficacy, and petroleum compatibility. The sign signifies the filter evaluations in environments exposed to petroleum aerosols:

N95, N99, & N100: These filters are not to be utilized with oil aerosols. All these ought to be used in environments subjected to particulates which usually do not contain oil. In many cases, the n- respirators could be reused multiple times.

R95, R99, R100: All these filters are oil resistant. The r- respirators may be utilized in atmospheres containing particulates almost some liquid or solid threat for example: oil-based hazards. All these are one-time use masks.

P95, P99, & P100: These filters have been oil proof. All these respirators can be utilized in virtually any environment confronted with hazardous particulates. The p-respirators are subject to a period of use limits.

The filter efficiency number denotes the proportion of airborne particulates that were removed in analyzing: 99% 95%, and 100%. It'll have a stamp of approval category printed on the mask when it is NIOSH approved subsequently.

It's also recommended that you speak with experienced industrial security employees concerning an assessment of your environment, before choosing the right mask.
