Effectiveness of Local Filters for Infection Control in Medical Examination Rooms
An experimental and modeling study was undertaken to evaluate the utility of local air filters for infection control. The ventilation provided by the portable filter that was tested not only exceeded regulatory guidelines, but was remarkably uniform throughout the room in spite of large variations in the air velocity. Furthermore, even partially enclosed regions with single openings that are commonly found in furnished rooms were adequately cleaned. The uniform ventilation is attributed to the rapid mixing arising from the flow of filtered air discharged from the filter. Ventilation of semi-enclosed regions appears to occur by a pulsationtype flow driven by relatively small pressure variations in the room. It is concluded that portable air filters are highly effective in removing particles from typical examination rooms and, because they also reduce the amount of contaminants entrained into the HVAC system, might be suitable for infection control at low-risk health facilities.
