With the help of a high-powered, 48-inch fan, Clean Air America, Inc.'s truck-mounted vacuum system extracts dust, dirt, and allergens out of ventilation systems at a rate of 16,000 cubic feet of air per minute. To put that in perspective, traditional portable or truck-mounted vacuums muster between 400 and 4,000 cubic feet per minute on a good day. Before each session, technicians send an infrared camera into the ductwork to map out every inch of dust or reveal enclaves of ninjas hiding there. Then they move in with special brushes and scrubbing tools, leaving homes with cleaner air and fewer odors.
