Abstract
Abstract An air purification planter is disclosed which comprises a receptacle; an aeration assembly; a pot-growing plant; and, a potting media. The receptacle is of the type utilized commercially. A portion of said aeration assembly is sized and proportioned to fit within said receptacle. In the preferred embodiment, a commercial receptacle is perforated near the bottom of said receptacle in order to permit communication of said aeration assembly from the interior to the exterior of said receptacle. The aeration assembly includes an electric fan which connects to the exterior end. The fan draws air through the potting media, by the root system, and through the aeration assembly, and recirculates the cleansed air. An alternative embodiment of the air purification planter utilizes a totem concept, and, comprises an aeration assembly; and a trellis-growing plant. In the alternate embodiment, the potting media is combined with activated charcoal to be wrapped about said aerating section.
