Abstract
Prior to the development of modern types of filters, medias, and varying efficiencies, the available filter media could remove only a relatively small percentage of the pathogenic organisms in an air stream. Because of this low efficiency most authorities believed it was better to use all outdoor air which contained fewer pathogenic organisms than to reuse, by recirculation, the more contaminated air from within the hospital for the ventilation of operating rooms and similar sensitive areas. Today, there are numerous types of filters to meet the needs of health facilities.
