    An advanced supply air filtration unit has been developed, and its performance was evaluated in the laboratory. The filter consists of an electrically enhanced particle filter and an adsorbent filter for gases. It has been designed for installation near supply air outlets. The performance of the filtration unit was measured in the laboratory. The results showed that the filtration efficiency for submicron particles was over 95% during the whole lifetime of the filter. The removal efficiency of the gas filter for toluene was also high, over 95%. An important advantage is the high efficiency with a low pressure drop that allows the filter to be installed in existing HVAC systems without extensive modifications. With the aid of the filter, protection against harmful or hazardous air contaminants can be improved energy efficiently in specific rooms or areas of a building.
