Remote filter holder: ideal for welding

By removing the filter attachment on the mask (simply twist the bayonet fitting) and attaching the breathing hose and remote filter holder, you can wear the filter behind your back.
The filter sits on a waist belt and can be moved to any position.
In turn, the mask itself is given a very shallow profile. This makes it ideal for welding, as it easily fits inside a welding shield or visor.
An additional benefit is that the filter is mounted well away from any welding hazards, such as sparks, heat and metal fumes.
