BURBANK, Calif. - A new Web site from Steril-Aire Inc. discusses how its ultraviolet-C technology may be used to control the spread of the avian or "bird" flu in buildings of all types. The information can be found by visiting www.uvckillsbirdflu.com. Steril-Aire's multi-patented UVC devices are designed for installation in air-conditioning and ventilation systems in buildings and homes. The UVC energy emitted by these devices typically destroys more than 90 percent of flu viruses and other microbes with each air change, company officials say. In doing so, the company says that the energy significantly lowers the number of harmful microbes in occupied spaces, reducing the potential spread of the flu virus. In addition, the company reports that UVC can control other viruses, including colds, SARS, measles and infectious bacteria such as pneumonia and whooping cough. Steril-Aire also claims that UVC can greatly reduce allergy and asthma symptoms caused by mold.
