Abstract
An aromatic odor neutralizer includes a dispenser housing with an internal passage between end walls and communicating with vents in the sides for aerodynamic airflow to efficiently absorb vapors from a vaporizer chamber within the dispenser housing. The vaporization chamber contains a wick with an end part immersed in fluid in a storage cup that is gravity fed from an air tight vessel by the use of air pathways exposed when the liquid level in the cup is reduced.
