Method of delivering a volatile composition into the air

A method of dispensing a volatile composition, the method comprising the steps of:

• providing a volatile composition dispenser, the volatile composition dispenser comprising a cartridge comprising a reservoir for containing the volatile composition, a delivery engine in fluid communication with the reservoir, an evaporative surface in fluid communication with the delivery engine, and an evaporative assistance element adjacent at least a portion of the evaporative surface, wherein the evaporative assistance element defines a maximum power output;
• starting a total emission program for the volatile composition dispenser at time zero when the volatile composition dispenser is first powered and the cartridge is new or refilled to be full of the volatile composition;
• increasing the energy applied by the evaporative assistance element to a first energy in a first energy boost period, wherein the first energy is the greatest energy within the first 24 hours of operation of the total emission program after time zero;
• operating the evaporative assistance element below the first energy over a first extended emission period following the step of increasing the energy applied to the evaporative assistance element;
• increasing the energy applied by the evaporative assistance element to a second energy in a second energy boost period, wherein the second energy is less than the first energy;
• operating the evaporative assistance element at or below the second energy over a second extended emission period, wherein the length of the second energy boost period is no more than half of the length of the second extended emission period;
• and
• increasing the energy applied by the evaporative assistance element to a third energy in a third energy boost period, wherein the third energy is greater than the first energy.
