Apparatus for dissipating a fragrance or malodor eliminator utilizes an infused disc which a user can place in either a rotating or a fixed position. The two states will dissipate a scent/malodor-eliminator at different rates. The disc is mounted on a shaft that secures the disc in an air stream. The shaft defines several positions at which the disc can be placed, as well as structures to retain the disc at a selected location along the shaft. The shaft is part of a support which includes a mechanism for securing the apparatus within the air stream. Air flow causes the disc to rotate and dissipate at one rate or to pass through a stationary disc at a second, lower rate, as a function of the position of the disc on the shaft. A method of imparting a scent or malodor eliminator to air is also disclosed.
