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 18):
A respirator comprising:\n a face mask configured to cover the face of a user and avoid covering an eye region of the face; and at least one air filter attached to the face mask and configured to filter unpurified air to provide breathable air; wherein the respirator also comprises a powered impeller unit mounted on the face mask and configured to compress and distribute the breathable air inside the face mask in an arc substantially parallel to the internal surface of the facemask; and the face mask forms a gap between an edge of the face mask and the user's face and configured to allow a positive flow of the breathable air together with exhaled air to exit the face mask and exclude ingress of external unpurified air.
