Abstract
The purpose of this project is to study the possibility of achieving a reduction of ultrafine particles in the indoor air by placing a filter at the outdoor-air inlet in residential buildings with exhaust ventilation or natural ventilation. This paper presents field measurements of airflow rates through the outdoor-air inlets in 24 apartments. Three different ventilation systems were included in the investigation. Air cleaners with an electrostatic filter were examined in two apartments. In addition, a wall outdoor-air inlet filter was examined fullscale
in a chamber of 32 m3 in the laboratory. The results showed that the supply air entered most of the examined apartments through the outdoor-air inlets. The results also showed that the effectiveness of an air-cleaning device ranged between 60 % and 80 %. In addition, the results show that the efficiency of the electrostatic inlet filter increases until airflow rates reach about 18 m3/h. When airflow rates are more than 18 m3/h, the filtration efficiency is
constantly around 50 %.
