The wide variety of microorganisms released into indoor air from animate and inanimate sources often include microbial pathogens and allergens, and exposure to them may be directly by inhalation or indirectly by contact with surfaces contaminated with airborne particles. Therefore, safe and effective microbial decontamination of indoor air can reduce the risk of exposure to such harmful agents. However, standardized and field-relevant test protocols remain unavailable to assess the claims of technologies already marketed or under development. This presentation will describe an economical and versatile aerobiology chamber and its use to study physical and chemical technologies to remove/inactivate a variety of human pathogens in experimentally contaminated indoor air.
