Abstract
The present invention describes an air quality containment unit for isolating a construction, renovation or maintenance project. The air quality containment unit contains dust, molds and other air-borne pollutants using a filter, such as a high-efficiency particulate air (HEPA) filter, to maintain a negative air pressure in the unit. The air quality containment unit includes at least one sealable orifice that allows workers to introduce, for example, an electrical cord into the unit without breaching containment.
