The particulate impact on air quality of typical domestic behaviours (e.g. cleaning and cooking) and their potential mitigation strategies (e.g. increasing ventilation) was investigated in the DOMESTIC unit at University of Chester. A 'typical day' based on the UK Time Use Survey of 2014-15 and tested under 2 separate ventilation conditions for 2 days each. This clearly indicated the impacts of different activities and the reduction of particulate levels with higher ventilation.
