The Airleaf Mini is an interesting product that makes use of your fan or air conditioner. It contains little beads filled with oils extracted from fir trees, which purifies air as it's blown through by cutting down the carbon dioxide and restricting production of oxygen radicals.

And that cute little plant motif is more than just for show: The height of the stem is adjustable — the taller it is, the higher the level of purification.

Produced by Nendo for Mikuni, a maker of purifying goods, the Airleaf Mini is refillable, designed to clip onto fans, vents and air-conditioners, comes in green or pink and costs ¥698.
