Abstract
An ambient environment modification mechanism such as a scent dispenser (which could also act as a filter) which may comprise a piston and a piston cylinder, receiving the piston, and forming a piston cylinder chamber volume when the piston is moved from an inserted position in the piston cylinder to a withdrawn position in the piston cylinder. The piston may have a hollow interior receiving an ambient air modification material holder, such as a cartridge, containing ambient air modification material. The hollow interior may be in fluid communication with the piston cylinder chamber volume at a first end of the hollow interior. A ventilation opening may be in fluid communication with the hollow interior at a second end of the hollow interior. A piston cylinder chamber volume forming mechanism, such as spring may move the piston relative to the piston cylinder from the inserted position to the withdrawn position.
