<p>PURPOSE: To protect articles for exhibition or storage from pollution by grasping the degree of pollution (degree of purification) of exhibition or storage environment quantitatively and maintaining the improved environment and post- improvement environment state. CONSTITUTION: Adsorptive sheets 5 for a wall surface 2a and a floor surface 2b of an exhibition room 1 are set facing each other closely for a given period to adsorb and remove pollution factors such as volatile components, water content and the like discharged from the wall surface 2a and the floor surface 2b by the adsorptive sheets 5. Pollution factor sensors are provided on the wall surfaces of the exhibition room improved to the environment suitable for exhibition, and when the amount of pollution factors in the atmosphere reaches the given level, a filter type air cleaner is driven for a given time based on a signal from the sensor to recover the environment.</p> |
