Tong's prompt to build a responsive and self-sustaining system yielded this geometrically structured air purifier. Courtesy of .
To help care for the plant, the chemistry model-like system includes a watering mechanism strung throughout the body. Embedded humidity sensors detect the moisture level and dispense water as needed.
Rather than relying on mechanical filters, like many household air purifiers do, Filtration Block uses miniature greenhouses. At around 12" x 12", the modules are large enough to house a plant that will produce clean air, but small enough to remain portable.
As this diagram shows, pores help draw polluted air into the cells. A plant will then naturally filter it and convert it into clean air, which fans then distribute back out into the outside environment.
