1. An air filtering device comprising: a rigid component comprising a rigid oval-shaped frame, with a top, oval-shaped edge, and a transparent face shield, the transparent face shield having a bottom, oval-shaped edge, the bottom, oval-shaped edge is attached along an entire top, oval-shaped edge of the frame;
wherein a bottom portion of the oval-shaped frame is configured to pass below the chin of a user and an upper portion of the oval-shaped frame is configured to pass above the user's forehead;
a substantially air-tight fabric component attached around the entire oval-shaped frame;
wherein the rigid component and the fabric component are configured to combine to cover an entire head of the user and configured to form a seal around the user's neck;
an intake port with an inlet filter located on the rigid oval-shaped frame to filter intake air entering the air filtering device;
an exhaust port with an exhaust filter located on the rigid oval-shaped frame to filter exhaust air exiting the air filtering device;
an air mover affixed to the oval-shaped frame causing filtered air to enter the intake port from outside the air filtering device and exhaust air to exit the exhaust port; and
a controller configured to adjust a rate at which the air mover moves air.
