Abstract
A method of dispensing a volatile active into the surrounding environment includes the steps of providing a fragrance dispenser having a housing, a fan disposed within the housing and having a airflow director, first and second chambers disposed within the housing, and first and second fragrances disposed in the first and second chambers. The first and second chambers include first and second shutters covering first and second outlets, and first and second heaters, respectively. The method further includes the steps of activating the first heater to volatilize the first fragrance for a first time period, simultaneously activating the fan and the opening the first shutter to dispense the volatilized first fragrance from the first chamber into the surrounding atmosphere, activating the second heater to volatilize the second fragrance for a second period of time, and simultaneously activating the fan and opening the second shutter to dispense the volatilized second fragrance from the second chamber into the surrounding atmosphere.
