My two cents on this is that your not going to find a simple, ready to click, solution. But really you need to think about what it is that you want to model.
If you want to model the heat exchange between the zone and the cavity, you can do that using ZoneMixing or Airflow Network.
If you want to model the air purification, I'm not sure how you'd do that exactly but I'd look at the ZoneContaminantXXXX objects such as the ZoneContaminantSourceAndSink:CarbonDioxide
