What Is An N95 Respirator Mask?

Disposable respirator masks have obtained elevated attention as of late with the spread of the H1N1 flu virus, although they have long been used for other purposes including occupational safety. N95 refers to a National Institute for Occupational Safety and Health (NIOSH) rating that's assigned to masks that meet a specified minimal standard for particle transmission. The N95 respirator mask is designed to filter as much as ninety five% of airborne particles 0.three microns or larger that may in any other case directly enter the nose and mouth of the wearer. These masks might also be worn by people who have a contagious illness to stop particles from leaving the nose and mouth of the wearer and putting others at risk. While such masks do not protect in opposition to particle transmission with one hundred% accuracy, they are often effective in stopping the spread of infection.

N95 masks will be purchased with our with out a valve to facilitate simpler breathing. Optimum protection is achieved when the respirator mask fits snugly to the face, covering the nostril and mouth without leaving open areas alongside the edge. Respirator masks should be fitted appropriately to the wearer and not be obstructed by facial hair or jewelry. A poorly fitted respirator mask has larger potential to permit air particles to enter by gaps along the sides of the mask, providing decrease ranges of protection against the inhalation or spread of particles than a well fitted one.

Respirator masks are widely used for occupational safety, and are notably common in industrial and health care facilities. Masks used in the workplace should be NIOSH-approved, that means they meet minimal requirements put forth by the National Institute for Occupational Safety and Health.

The meant purpose should be saved in mind when purchasing respirator masks. Completely different types are designed for particular purposes and offer varying levels of protection. One other consideration is whether the masks comprises latex, an allergen for some people. Latex free N95 respirator masks are available, and can be marked as such.
