Peace and quiet may be hard to come by. Good fragrance? We can help with that. The Harmony Ultrasonic Diffuser has soft waves across its matte white ceramic sleeve, giving it a lovely spot on a shelf even when it’s off.

Add water and a few drops of Farm House diffuser oil, then choose continuous mist for up to 4 hours or intermittent mist for up to 8. Set one of eight light colors or let them rotate. The diffuser shuts off automatically when the water runs out.

Details: 100 mL water tank. Includes a decorative sleeve, measuring cup, and 5-foot cord. Diffuser Oils sold separately.
