A method for controlling an amount of evaporated scented material emitted from an air freshener device include generating a first control signal to induce the motor to rotate fan blades at a first rotational speed during a first time interval which urges air flow toward the aperture of the container to induce evaporation of the scented material in the container. The method further includes generating additional control signals to induce the motor to increase a rotational speed of the fan blades during a second time interval to increase air flow toward the aperture of the container, the second time interval being after the first time interval, such that first and second mass rates of evaporated scented material from the container during the first and second time intervals, respectively, are maintained within a predetermined mass rate range.
