A novel apparatus for the treatment, e.g., cleaning, humidifying, filtration and/or detoxifying, of ambient air incorporates a plant, soil, roots and a water reservoir to allow for effective filtration of air over an extended period of time. In particular, the device is designed with an air impeller system such that external “dirty” air is circulated within the device in the proximity of the plant, soil, roots and/or water reservoir, thereby removing impurities, toxins and other undesirable chemicals from the air. The apparatus and methods of the present invention are readily applicable to a number of applications where air treatment is desired, e.g., household use. Moreover, by incorporating a plant system, the apparatus serves not only a functional but an aesthetic purpose as well.

1. A method for treating air, the method comprising: drawing air into an internal volume defined by a housing;directing air past leaves of a plant, the leaves disposed generally within the internal volume prior to the air passing through a soil substrate disposed in the housing and supporting roots

1. A method for treating air, the method comprising: drawing air into an internal volume defined by a housing;directing air past leaves of a plant, the leaves disposed generally within the internal volume prior to the air passing through a soil substrate disposed in the housing and supporting roots of the plant;substantially removing impurities from the air; andmoving the air from the housing to an external environment. 2. The method of claim 1, further comprising contacting the air with water in a water reservoir, or with water vapor that substantially originated from a water reservoir. 3. The method of claim 1 or 2, wherein directing air past leaves of the plant prior to the air passing through the soil substrate supporting roots of the plant comprises operating at least one fan to cause ambient air to enter the internal volume defined by the housing. 4. The method of claim 3 further comprising varying a ratio of a speed of a first fan to a speed of a second fan. 5. The method of claim 1, wherein moving air from the internal volume to an external environment comprises operating a fan to cause air in the internal volume of the housing to be discharged out of the housing.
