Futuristic Ventilation Systems

Millions of cases of illness among office workers each year could be preventing by installing germ-killing lights in the ventilation systems, researchers say. What kind of implication could this have for child care centers? For the study published in The Lancet, researchers installed ultraviolet germicidal irradiation equipment to kill microbes in the drip pans and cooling coils of ventilation systems in three office buildings. They found that 99% of the germs were killed by the lights. Central air conditioning systems are almost always contaminated with microbes like bacteria, fungi and protozoa that have been linked to a variety of health problems. Although the costs of installing such a system is costly, in the long run it could mean that child care just might become more sanitary.
