N95 Respirator (20/Box)

Not all masks are made the same. Filtering facepiece respirators, commonly referred to as N95 masks, are regulated by the National Institute for Occupational Safety and Health. N95 respirators reduce the wearer's exposure to airborne particles, from small particle aerosols to large droplets. Here is a breakdown of what an N95 mask is: N: This is a Respirator Rating Letter Class. It stands for “Non-Oil” meaning that if no oil-based particulates are detected, then you can use the mask in that environment. 95: Masks ending in a 95, have a 95 percent efficiency. Material: The filtration material on the mask is an electrostatic non-woven polypropylene fibre.
