“…This communication describes the construction and operation of two identical experimental rooms in which it is possible to produce and maintain a wide range of temperature and humidity with or without exchange of the room air. The ability to maintain a large air mass under constant conditions makes it possible to study the effects of different atmospheric states on air-suspended bacteria and viruses in relation to their survival, particle size, humidification, killing by lethal vapors, and host susceptibility. …”
