Abstract
A personal air filtration device and methods of using the same for providing a zone of filtered air proximate a breathing zone of a user are described. A blower provides an air flow to a head support which delivers the air flow to a zone proximate the users head. The air flow passes through a filter. The filter can be a point of delivery filter disposed about an air permeable surface of the head support. The delivered air flow can provide a laminar air flow defining a zone of filtered air about the user's breathing zone.
