An inflatable membrane stadium is built in a school in Beijing on Dec.1, 2015. Its PM2.5 filter system can screen the air flowing inside and transfer the clean air into the pneumatic membrane through air-ducts. In addition, the air pressure in the membrane is greater than outdoor air pressure, which keeps the fine particles out of the door.
