Using a unique technology, the aroma diffuser Lea diffuses the aroma throughout the room directly from the fragrance oil bottle. Thanks to rechargeable batteries, Lea operates without a cable, creating a soothing fragrant experience anywhere. The interval mode ensures a long running time: the aroma diffuser Lea operates for 10 minutes followed by a 20-minute break. If Lea should diffuse aroma in response to brightness in the room, then the daylight mode is the correct choice.
