The Woodgrain Ultrasonic Aromatherapy Diffuser from ECVISION is a vase shaped aroma diffuser and air humidifier. It works in three modes of mist and light, and you can use it for eight hours straight before it needs to be replenished. If it runs out of water, it will switch off automatically. This ensures that it’s safe to use even when you’re asleep or not at home. It’s small and portable and consumes a very small amount of power, and is easy to clean. The best part is that the look and feel of the natural woodgrain vase makes this device a very nice addition to any room in your home, office, spa, hotel lobby or reception, lounges, conference rooms, hospital and clinic waiting rooms, etc.
