The Aroma Om Deluxe is a heat-free essential oil diffuser, the largest and longest-running model in its line. It uses ultrasonic vibration to turn water and essential oil into a cool mist, so the scent is never heated. It runs quietly enough for a bedroom or office and is styled as a decor piece rather than a plain appliance. Buyers rate it well overall, and its main edge over smaller rivals is longer run time and a bigger tank; the trade-offs are size and the upkeep a water-based diffuser needs.
