Fresh Interior Air

Most newer cars have the option to stop outside air from coming into the car and re-circulating the air already in the car. My idea is to have a compressed air cylinder mounted in the car that is filled with fresh, clean, mountain or ocean air. The cylinder output can be regulated and set with just enough pressure to force out the stale air as desired. Replacement or refilling the air cylinders can be set up at gas stations. Fresh Mountain Air would be the key, not just city air from the same polluted area, similar to bottled Mountain Spring water replacing tap water in some area. This might be an appealing option for cars sold in China, Japan and other areas of high pollution, high traffic congestion, and for people with allergies and fume sensitiveness.
