Abstract
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.
Claims5
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;
- and
- moving the air from the housing to an external environment.
