Bel-Air indoor air filtration system

The Bel-Air indoor air filtration system uses nature to purify the air around you – it does so by sucking in dirty air, runing it through a plant’s leaves, roots, where the air will then receive a “humid bath” before being released back to the atmosphere. I wonder if smoking in the vicinity of the Bel-Air indoor air filtration system would cause unnecessary stress to the plants within. No idea on how efficient it would be either, as one will surely need more than a couple of such plants even for a small apartment. Interesting green idea, but the cost-effectiveness of it is questionable.
