Metro Air Purifier
Metro Air Purifier

A subway door with high-efficiency foam to improve the impact of high concentrations of PM2.5 generated by metro train. Due to poor air circulation underground, suspended particles on the surface are brought underground which is difficult to discharge. When the train enters the station, the piston principle pushes a lot of wind from the tunnel into the platform, causing PM2.5 to rise and causing instant exposure to passengers while waiting for the train on the platform.
