The Biofiltration of Indoor Air II: Microbial Loading of the Indoor Space

Jeff Mallany1, Alan Darlington and Michael Dixon

ABSTRACT
Two ecologically complex indoor air biofilters were tested for their impact on selected airborne spore concentrations. Fungal and bacterial spore concentrations were monitored during the commissioning of a biofilter and found to remain consistent with reference site. While the water path was devoid of the pathogen Legionella pneumophilia, irrigation schedules could impact air quality. The air path was not seen to add to the fungal or bacterial concentrations of the ambient air.
