Abstract
The instant devices and approach provide a way to provide custom scented fluids (or air freshener) in the form of evaporated scented air and also atomized scented liquids. It combines a vessel capable of constraining scented fluids or air fresheners with a semipermeable membrane for dispersing evaporated scented air and also an atomizer for dispersing scented liquids into the air and thereby eliminates the need for secondary valves.
