Elevator installations are equipped with devices (12) for releasing aromatic substances in elevator cars and on the landings. Each of the aroma generating devices (12) has controllable valves to control the release of a number of different aromas and fragrances through outlet jets (13) which can be positioned at a limited distance from the device. The aromatic substances are released in doses of such small quantity that they are only perceptible within a maximum radius of approximately 0.5 m about the outlet jet and that this perceptibility lasts for only some seconds. This makes it possible in an elevator car (5) or on a landing to release simultaneously from a number of jets (13) different fragrances and aromas without their combining with or negatively affecting each other.
