Abstract
An air pollution control apparatus usable for capturing airborne pollutants present in a relatively confined environment. The apparatus is a portable airborne-pollutant capturing device movable to a site of pollutant origin and having at least one airborne-pollutant collector member, a vacuum system, and a filter system. The filter system can include one filter or more than one identical or different filters chosen for enhanced filtration capabilities in relation to pollutants present. Preferably, more than one type of filter can be accommodated simultaneously to thereby capture multiple pollutants. Fugitive particulate is captured by positioning the airborne-pollutant collector member proximate the activity causing pollution, and operating the collector member simultaneously with the polluting activity to thereby cause particulate to be captured by the filter system.
