A video detailing the levels of protection each type of respirators gives the user.
Starting with dust masks which are next to useless, to half-face respirators offering much better protection.
To full-face air-purifying respirators (gas masks) offering protection of the eyes and face as well as the respirator system.
To air-supplying respirators which work in zero oxygen environments and create positive pressure, up to the re-breather closed circuit respirators.
