Abstract
An aromatic odor neutralizer includes a vaporization chamber containing a wick with an end part immersed in fluid in a storage cup that is gravity fed from an airtight vessel by the use of air pathways exposed when the liquid level in the cup is reduced. The vaporization chamber is located in 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.
