An air supply system in building elevators for the purpose of providing continuous purified and filtered exterior air for the improved safety of elevator cab passengers. The air supply system is separate from that of the building. System components include: an air intake means in the top of the building to receive exterior air; an air filtering and purifying mechanism; an air blower and compressor; air heating and cooling unit; a pressure controlled air plenum; a flexible vertical lightweight traveling tube that continuously carries purified air from the plenum near the top of the building to the cab interior, a flexible vertical lightweight air exhaust traveling tube that continuously carries spent air from the cab interior discharge conduit to the building exterior exhaust, wherein both tubes are affixed to the elevator traveling cable and extend the height of the building.
