Abstract:
A mask or shield comprising a flow of positive pressure air directed through substantially opposing jets that creates a stream of laminar flow filtered air to create a turbulent air pocket therein for supplying filtered breathing air to a wearer's face and to exclude outside unpurified air. Also a mask or shield comprising a flow of positive pressure air directed via a powered impeller unit that is configured to distribute positively pressurised filtered breathable air inside the face mask in a substantially 360° plane or arc substantially parallel to the internal surface of the face mask and to exclude external unpurified air. The mask is separated from and does not form a seal around a wearer's face unless required such as in a deadly environment or malfunction.

Claim (Index 1):
A respirator comprising:\n a face shield with an attachment means for attaching the face shield to a face region of a wearer; at least two substantially opposing air supply lines in fluid communication with each side of the face shield to provide a positive stream of laminar flow of air; and an air filter for filtration of the laminar flow of air; wherein the at least two opposing air supply lines are spaced apart and directed to allow streams of the laminar flow of filtered air to collide at an intersection region within a cavity of the face shield creating a turbulent flow of air that radiates away from the intersection region therein for supplying filtered breathing air to a wearer's face region and exclusion of outside unpurified air, wherein the face shield does not form a seal around the face region of the wearer, and wherein the face shield is shaped to avoid covering an eye region of the wearer when attached to the face region.
