An elevator ventilation system comprising an ultraviolet source that illuminates elevator system air blown through an illumination chamber, and an air filter that filters the air as it flows through the chamber. The ultraviolet source is blocked from view from outside the illumination chamber. An air curtain emitter may expel a curtain of air across the elevator doorway, limiting air communication between an elevator interior and the elevator landing when elevator doors are open. An air outlet may be shaped to receive an elevator light fixture and to expel air into the elevator interior via an aperture adjacent the light fixture. An air curtain emitter may comprise an air outlet slot shaped to expel a curtain of air separating an interior of the elevator car into at least two air compartments defined by the “barrier” of the air curtain.
