Air quality is an important factor in health. Air in classroom, where many students are gathered in a small space, is easily polluted. Especially in underdeveloped areas, the air gets worse faster because of old building and many students.

O-POT is easy to use and manage, and minimizing production unit cost and power use. Water Ring rotates and sprays rain-likely in the case, purifies the incoming air, and sterilized through plants and released with high-quality oxygen to student eco-friendly. Children develop their responsibility while planting, and emotionally develop by interacting with plants.
