In the last thirty years, particular attention has been paid to the reduction of outdoor pollution, but only recently has the international scientific community dealt with air contamination in closed environments. In fact, it has been found that people today spend ۸۰-۹۰% of their time in confined spaces, and the reports of disturbances that arise in living spaces, living rooms, collective life or work have grown and become increasingly frequent. The changes that have taken place in lifestyles such as the outsourcing of activities and precariousness, the increase in the female working population, the increased sensitivity to health and safety, the increased demand for well-being and comfort, have contributed to the continuous request for better conditions to live in. And the adoption of new construction technologies, the greater use of sound-absorbing and insulating substances, the need for hermetic closure of buildings, the greater use of air conditioning and air conditioning systems have instead increased some risks inside buildings. School is one of the closed spaces that suffer from air pollution. To solve this problem, this research has presented a series of solutions that can be used.
