Abstract
A laminar flow purified air system includes a halo-shaped body configured to provide a laminar air flow barrier between a user of the existing hat and an ambient environment surrounding the user. Such a halo-shaped body has an air inlet and a laminar air outlet and a pressure chamber in fluid communication with both the air inlet and the laminar air outlet. The air inlet and the pressure chamber are configured to force laminar air out from the laminar air outlet and thereby create the laminar air flow barrier.
