  • Air filtration system and method of use
    Patent number: 6666910
    Abstract: An air filtration system for filtering air drawn into a substantially enclosed environment, such as a room, having an access opening includes a box having sidewalls, a flexible sheet of substantially air-impermeable material sized to cover the access opening of the environment, at least one filter having a body and a rigid rim encircling the body, and a pump having an inlet conduit through which air is drawn into the pump during pump operation. The components can be assembled to form a filter-supporting unit and, with the aid of the flexible sheet, sealed across the access opening to convert the environment into a shelter into which filtered air is pumped.
