ABSTRACT:
The invention is an air filtration and purification system, utilizing the filtering ability of the various elements in a potting medium for plants, water films and free water surface in contact with the roots of these plants, and the power of live plants to assimilate various odors, pollutants and in combination with commercially available air filter materials, such as activated charcoal, and other specialized granular air filter materials, to meet many air filtration requirements. The system consists of a unique flower pot, with a potting medium cavity for specially formulated potting medium which permits the free flow of ambient air upon application of a partial vacuum, and sustains the normal growth of the plant in the flower pot, and a built-in filter chamber, which is adaptable to any commercially available granular air filter material. Application of a vacuum condition in the filter chamber purges the micro and macro pores in the potting medium, causing the ambient air to flow into the medium, facilitating an active and turbulent interaction at the micro level in the pores, between the pollutants in the air stream and the various filter elements in the flower pot. The interactions also filter out radon gas, and also its short lived progenies and their long lived decay products.
