Andrea plant-based air purifier

Plants are Mother Nature's filters for dirty air, so why not use them to power your air purifer? Conceived by French designer Mathieu Lehanneur, Andrea pulls air in through a quiet fan, which then propels it through the leaves and root system of the plant, then out through the soil and back into the room. Air doesn't get much fresher than that. And the best part is that you can pick whatever plant you want to fit in the pod.
