Plant Air Purifier –  The Plant Air Purifier® is an air filtration system that consists of a planter, specially developed ceramic growing media, activated carbon and a low-voltage power supply. The planter itself consists of a perforated inner pot and a unique outer reservoir that holds enough water for up to one week. The planter has an electric fan to ventilate the system and a low-water switch in the water reservoir to turn off the fan when the water runs low. All that is required is a plant, periodic watering and a dose of nutrients every few months.  Made in the U.S.A.
