Most people using firearms, especially on enclosed shooting ranges, know how harmful lead is. By default, shooting ranges must have perfect ventilation. Moreover, non-toxic ammunition is becoming more and more popular, all of this for the sake of our health. Project Black's Tactical Respirator protective mask, is an interesting product in this context.

The mask has been designed to protect against lead fumes in a training/tactical environment. Project Black also protects the user against dust and other harmful particles, for example during room "breaching" or in other dusty environments.

The mask uses replaceable electrostatic filters that are 98.6% effective and block airborne contaminants up to 0.1 microns. Medical silicone was used for sealing.
The mask can be worn with glasses and NVG thanks to the downward exhaust valves that prevent fogging.
