Abstract

The aim of this study was to examine the feasibility of a new efficient supply air filter system in reducing indoor submicrometer particle concentrations. The filter consists of an electrically enhanced particle filter combined with an adsorbent filter. A test filter was installed in the supply air of an office room in Helsinki city centre and its performance was evaluated by measuring pressure drop and particle filtration efficiency. The effect of improved filtration on indoor air quality was demonstrated by measuring indoor particle concentrations both in the test room and in a reference room. Results showed that the filtration efficiency for 0.3 µm size particles was high, 99.9 % despite of a fairly low pressure drop (40 Pa at airflow of 72 l/s). Use of enhanced supply air filtration may be an effective control method in situations where polluted ambient air degrades indoor air quality.
