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