In the 1980s, NASA investigated how the airborne impurities in the space station could best be removed from the enclosed indoorspace. The research came to a logical conclusion that a human lives in symbiosis with plants and a closed spacecraft requires plants to cleanse poisons extracting from human itself and from spacecraft building materials. According to a NASA's research, especially the plant roots and microbes can effectively use and clean the impurities from the air. This thing cleans the air and automatically supplies water to the plant.
