OBJECTIVE: The development of a new method for achieving respiratory isolation in hospitals, clinics, and residential facilities, in response to the increasing risk of transmission of tuberculosis and the limitations of the currently available isolation systems. DESIGN: Ultraviolet (UV) light and ultra-low-penetration air filtration were combined with a ventilation unit and adapted for use in modular isolation rooms or for conversion of existing rooms. RESULTS: The ventilation-filtration unit efficiently cleared bacterial aerosols and particles > 0.2 microns from the air, maintained required negative pressures and airflows, and provided directional airflow within rooms.
