Abstract

See full text

A germicidal method and apparatus for destroying airborne pathogenic bacteria such as tuberculosis bacteria using ultraviolet light. Air is drawn through a filter and into a sterilization chamber that is irradiated with ultraviolet light, and out through an exhaust opening. Consideration for the characteristics of the room in which the apparatus is installed and the positioning of the installation allows effective prevention of transmission of disease through expectoration and inhalation of airborne microdroplets of bacteria-containing sputum. The filter is of the low-density type which traps large particulates, but not small particulates of the size of the microdroplets, so that the filter does not become a bacteria colonization site. Baffles on the air intake opening and air exhaust opening to prevent ultraviolet light from escaping into the environment. The sterilization chamber is constructed such that the air passes the ultraviolet light bulbs twice as it circulates therethrough.
