Abstract
A head-mounted, hat-like device includes components for guiding a stream of air flowing in a direction frontwardly of the face of the user and filter components for filtering the stream of air. The air flow guiding components include a fan fixedly mounted to a housing, a directional member mounted to the visor portion of the housing for directing air frontwardly of the person's face and a conduit for interconnecting the directional component and the fan device. The fan device draws ambient air including smoke and other by-products of burning tobacco through the directional component and along the conduit to be discharged by the fan device through a conventional tobacco by-product filter component, thereby cleansing the stream of air before it is released to the air space above the person.
