The present invention relates in particular to a plant cultivator that purifies indoor air, and is a box-shaped enclosure and a potted plant having the same shape as the enclosure, and is manufactured in a size such that a small gap is formed with the interior wall of the enclosure while being embedded in the enclosure. It is composed of a flower pot formed in the pot, and culture soil filled in the pot, zeolite balls, and cultivation soil made of gravel. The enclosure communicates with the ventilation window of the pot embedded in the enclosure, and a position facing each other among the walls forming the body of the enclosure The air inlet and the air outlet are formed on the wall of the wall, and the zeolite ball layer on which the zeolite balls are stacked and the gravel layer on which the gravel is stacked are stacked at a height that overlaps the ventilation window, so that nutrient solution and water are not wasted and can be used for plant cultivation. The most economical and eco-friendly indoor air purification because the pollen has self-sustaining ability to prevent plant roots from decaying, so no effort is required for water drainage, and the air purification is eco-friendly and does not require any power consumption or filter replacement cost. Since the cultivation machine has only the volume required for plant growth, unlike the conventional greenhouse that heats or cools the entire greenhouse and requires enormous energy, only the inside of the enclosure only needs to provide cooling and heating, so the energy required is incomparable. We intend to provide a minimizing air purification planting machine.본 발명은 특히 실내 공기를 정화시키는 식물 재배기에 관한 것으로서, 상자 형태의 함체와, 상기 함체와 동일한 형상의 화분으로서, 함체에 내장되면서 함체 내벽과 미소 간격이 형성되는 크기로 제작되며, 통기창이 벽면에 형성되는 화분 및, 화분에 채워지는 배양토와, 제올라이트 볼 및, 자갈로 이루어지는 재배 토양으로 구성되며, 함체에는 함체에 내장되는 화분의 통기창과 연통되며, 함체의 몸체를 이루는 벽면 중 서로 마주보는 위치의 벽면에 각각 공기 유입구와 공기 배출구가 형성되고, 제올라이트 볼이 적층된 제올라이트 볼 층과 자갈이 적층되는 자갈층은 통기창과 중첩되는 높이로 적층됨으로써, 양액과 물이 낭비되지 않고 전량 식물 재배에
