Removal of Indoor Ozone with Reactive Materials: Preliminary Results and Implications

Ozone is an air pollutant that not only has adverse health effects on its own, but is also a strong reactive indoor, creating even more harmful by-products, at rates that can compete with air exchanges. Hence, passively removing ozone from indoor environments, using Passive Reactive Materials (PRM), would have beneficial health effects and would conform with reductions in building energy consumption. Short-term experiments have shown that activated carbon has this ability. The current study will focus on evaluating how the ozone removal efficiencies of activated carbon mats and three green building materials vary over time in real environments. Samples of each material are placed in five fields locations in Austin, where environmental conditions are monitored. The samples ozone removal efficiencies and ozone related secondary emissions are measured monthly
