Pollution by air filters: Continuous vs intermittent air flow
conference paper
Within the framework of the EU research project Airless, a long-term experiment of 28 weeks was carried out to investigate the influence of intermittent airflow compared to continuous airflow on the pollution effect of glass fibre filters (F7). No statistical relevant differences between odour intensity and VOC-emissions of the filter exposed to the continuous flow and the filter exposed to the intermittent flow was observed. Microbiological growth did occur on the soiled side of the filters, but also on the 'clean' side, specifically for the filter with the intermittent flow. Despite this growth on filters, no significant increase of the odour intensity of the air passing the filters was observed.
