Air Filtration Ecosystem

After reading about NASA experiments where they found plants which could filter toxins (thanks wikipedia) out of the air, I became curious if these natural air filters, and if an ecosystem could run one of these filters. Of course automated data collection here would be really interesting, as a means of better understanding the results of the filter. Here is a proposal of what that system would look like in our 12th floor lab.

 

This prototype would feature a vertical garden using felt containers as a filter substrate and as a vehicle to grow plants.
