Enjoy the mess-free, waterless diffuser that gives you a soothing aromatherapy scent for any space. A revolutionary alternative to the traditional diffuser, it comes at 3 lbs and uses filtered air rather than water to bring a more natural airflow.

The waterless diffuser works using intermittent mist intervals with pauses to achieve the precise aroma level you desire. There may be oil residue in the reservoir.
