Indoor air

Indoor air is conceptually equivalent to the ambient air , so the air in rooms inside buildings (eg. As residential buildings, office buildings, hospitals, schools, etc.), other structures (eg. As tunnels, bunkers, towers etc.) as well as in vehicles (e.g. cruise ships, airplanes, subways etc.).

With the implementation of European directives concerning the indoor air quality in national law by the legislature was the international term for room air: indoor air than indoor air translated. The term indoor air as a type of air therefore often appears in connection with indoor air quality.
