The evolution of clean air technology.
Ultra clean air ceilings were developed in the 1960s with the objective of reducing wound infections from airborne colony forming units, especially for orthopaedic surgery. Current designs confine themselves to this single objective, which has been achieved. Infections have been reduced to very low levels.
