The apparatus comprises a fragrance release system comprising a wick, at least one diffuser, the surface area of the diffuser in contact with ambient air being larger than the surface area of the wick in contact with ambient air, and a container to hold the wick, a fragrance preparation that is stored in the container, the fragrance preparation being transported through the wick to the diffuser by capillary action against the direction of gravity when the wick is housed in the container, wherein the substantially cylindrical wick is formed from at least two mutually different plant-based fibrous materials, the first material forming a core and the second material surrounding this core, and the difference between the contact angle of the core material and that of the material surrounding the core relative to water being at least 10°, the core material having the small contact angle, preferably between 0° and 90°, relative to water.
