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.
