Abstract
A device is provided that is capable of circulating air throughout a personal space as well as collecting and preventing the build up of dust and other particulate matter by drawing in air from the surrounding environment and removing some dust, allergens and other such particulate matter therefrom. The filtered air is then expelled out of the device and back into the surrounding environment. The device includes a housing defining an interior space having a motor and fan assembly disposed therein. The housing includes an inlet with a filter provided therein such that air drawn in through the inlet is filtered. The air is then expelled through a circumferentially disposed outlet. The filter element preferably includes a lock and key system configured to prevent operation of the device in the absence of a properly keyed filter.
