ABSTRACT:
Treatment of room air so as to reduce its content of gaseous and particulate liquid and/or solid contaminants and then to return the air to the ambient atmosphere, with the aid of green plants in suitable apparatus. An open-top housing is divided into upper and lower portions by a foraminous plate adapted to support a potting soil layer. The housing has in its upper portion a water-retaining support for the root ball of a plant and has in its lower portion an air-pump to draw room air in via a bottom opening, to pass it upward through the potting soil and past the plant roots, through an overlying layer of charcoal or the like, out the open top and past the plant leaves, and finally back into the room. Continuous or repetitive intermittent circulation of room air in such manner through such apparatus results in prompt and effective removal of cigarette smoke and numerous other contaminants, at the same time rendering the environment more attractive to persons benefitting from such purifications of the air they are necessarily breathing.
