Dynamic Botanical Filtration System for Indoor Air Purification
<p>A dynamic botanical air filtration (DBAF) system was developed, tested and modeled for indoor air purification. The DBAF system consisted of an activated-carbon/hydroculture-based root bed for potted-plant, a fan for driving air through the root bed for purification, and an irrigation system for …

Study of building material emissions and indoor air quality
… materials and furnishings emit a wide variety of indoor pollutants, such as volatile organic compounds (VOCs). At present, no accurate models are available to characterize material emissions and sorption under realistic indoor conditions. The objective of this thesis is to fill that gap. Using the …

The effect of indoor air filtration on contaminant distribution and occupant exposure
Poor indoor air quality, driven by the presence of airborne contaminants, can have a significant effect on human health particularly given that we typically spend upwards of 80% of our time indoors. A potential solution for improving indoor air quality is to filter the air inside buildings, thereby …
