11 Facts About N95 mask

The N95 mask type is the most common particulate-filtering facepiece respirator.

N95 mask filter was invented by Taiwanese-American Peter Tsai and his team, and received its U S patent in 1995.

N95 mask respirators are considered similar to other respirators regulated under non-U.

However, NIOSH found that some products labeled "KN95 mask" failed to meet these standards, some of them filtering out as little as one percent.

N95 mask respirator requires a fine mesh of synthetic polymer fibers, specifically a nonwoven polypropylene fabric.

N95 mask respirators were originally designed for industrial use in sectors such as mining, construction, and painting.

Unlike a respirator, a surgical N95 mask is designed to provide barrier protection against droplets and does not have an air-tight seal and thus does not protect its wearer against airborne particles such as virus material to the same extent.

Disposable filtering facepiece respirators such as N95 mask respirators are not approved for routine decontamination and reuse as standard of care.

Surgical N95 mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment.

Originally designed for industrial use, N95 mask respirators became a healthcare standard subsequent to virus-blocking technology invented by University of Tennessee professor Peter Tsai, and patented in 1995.

Production of N95 mask respirators was limited due to constraints on the supply of nonwoven polypropylene fabric as well as the cessation of exports from China.
