An air purification device that attaches to the output vent of fans and air conditioners. The device is filled with tiny beads impregnated with essential oils extracted from fir trees. When air flows through the beads, it reduces and removes carbon dioxide in the atmosphere and restricts the production of radical oxygen. The device’s form recalls a new shoot sprouting from a small pot. Air purification increases as the ‘new shoot’ grows, allowing users to adjust it intuitively and providing a visual measure of air purification.
