This ventilator gas mask provides protection to the face, eyes, and respiratory system from toxic gases, vapors, and aerosols including radioactive dust and biological contaminants. The neck strap and five-point harness make it extremely easy to adjust for a comfortable and secure fit. The package includes a sealed 40mm NATO filter.

There are two types of respirators: Air-purifying respirators, also known as “gas masks”, which decontaminate the air by forcing it through a filter, and air-supplied respirators, which deliver fresh oxygen from a fully-sealed tank.
