description Various embodiments of the present disclosure provide a portable industrial air filtration device employing an annular dual filter assembly to capture and remove impurities from the air surrounding the air filtration device, enabling the air filtration device to quickly and efficiently improve the quality and safety of the air. The air filtration device includes a two-piece housing including a lower housing component and a locking cover removably attachable to the lower housing component. The dual filter assembly is mounted within the housing between the locking cover and the lower housing component, and includes a removable self-supporting outer pre-filter surrounding a separately removable inner HEPA filter. The pre-filter initially filters the surrounding air by capturing relatively large or coarse impurities, and the HEPA filter further filters the air pulled through the pre-filter by capturing relatively small or fine impurities.
