Abstract
Portable devices for mitigating the accumulation and localized settling of airborne particulates are provided. The devices establish airflow patterns which push or carry various airborne particulates outwardly away therefrom, thereby establishing a localized zone having relatively fewer airborne particulates. Correspondingly, each the devices establishes a localized zone, defined circumferentially about the perimeter of the device, in which there is relatively less surface accumulation of particulates which were previously airborne and settled out. The devices establish such airflow patterns by proving a fan which draws a volume of air axially through a top portion of the device, then pushes the volume of air axially down through the device where it is radially emitted from the bottom portion of the device, defining a circumferentially expanding plane of airflow.
