1. A device for filtering air for a user comprising:
a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion above the user's head and a lower portion proximate to and spaced apart from the user's chin;
an intake aperture formed in the frame;
an intake air filter covering the intake aperture;
an air mover chamber attached with an air-tight seal to an inside surface of the frame and communicating on one end with the intake air filter and communicating on another end with a filtered air supply inlet inside the device;
an air mover disposed within the air mover chamber and configured to draw air through the intake air filter and push air out the filtered air supply inlet;
an exhaust aperture formed in the frame;
an exhaust air filter covering the exhaust aperture;
a transparent face shield attached with an air-tight seal to a front surface of the frame, the shield providing a space for air between an inside surface of the face shield and the user's face; and
a fabric component comprising:
a first portion that is air permeable configured to cover the frame and filters; and
a second portion that is air impermeable extending from a back surface of the frame to cover a remaining portion of the user's head and encircle the user's neck.
