Often the terms "air scrubber" and "negative air machine" are used interchangeably. However, the two terms refer to very different applications. An air scrubber stands alone in the center of a room without any ducting attached. The air it filters is recirculated to the surrounding area. An air scrubber application helps improve the general air quality of the jobsite. A negative air machine uses ducting to remove contaminated air from a sealed containment area. The filtered air is exhausted outside of the containment. This creates negative air pressure (a slight vacuum effect) inside the containment relative to surrounding areas. A negative air machine application helps limit the spread of contaminants to other areas inside the structure.
