GREEN AIR is a low-cost, space-efficient air purification system that uses plants to reduce toxins in the air. The wall-mounted ceramic planter contains a small 115 VAC fan that slowly pushes air through the soil to the plant’s roots, a process that breaks down toxins equal to that of 15 regular plants. A conical bottom allows users to easily replace plants without interfering with the fan. Because over-watering is the number one reason indoor plants die, an ambient temperature sensor, which looks like a droplet of water, changes from blue to brown to indicate when and how much water the plant needs.
