Twenty-three articles where analyzed and gathered by the focused theme; patterns and principles for maintaining the air quality; air quality and isolation of microorganism; air quality and occurrence of infection. The standard of quality quotes: ventilation, maintenance and cleanness of climatization systems. Aspergillus, Legionella, Acinetobacter, Clostridium, Nocardia, among others where found in air conditioned devices and the first three ones being responsable for booms of HI.
