ABSTRACT:
This invention relates to a dual reusable filter respirator system. The respirator can be worn in dust, mist and fume environments for very long periods of time, while providing increased visibility, safety and comfort for the respirator wearer. A significant feature of the respirator is a pair of triangular shaped filter housings which allow the area of the filter media to be increased while at the same time reducing filter housing obstructions to the vision of the respirator wearer and creating a greater overall compactness of design.
