ABSTRACT:
By method of dispensing vapor, preferably perfumed vapor, to the air in a room from a vapor dispensing substance, vapor is dispensed by means of an electrically controlled control device for controlling the vapor dispensation of the vapor dispensing substance, and an electrical circuit for controlling the current supply to the control device. By the fact that the electrical circuit is supplying a time controlled, gradually increasing current supply to the control device in time periods with intermediate periods of no current supply to the control device is achieved that the concentration of the vapor dispensed is kept at a constant level, until the vapor dispensation substance has been used up.
