Ultrasonic aromatherapy machine: The aromatherapy machine uses ultrasonic technology to generate water mist, which can increase the humidity of the air. Improve the quality of your home's ambience with an aroma diffuser, mask pet or smoking odors, and protect your family from over-drying seasons, dust, and more! Remote Control: Our essential oil diffuser comes with an easy-to-use remote control to change lighting and misting modes and set the humidifier's timer. It runs smoothly without noise, giving you a quiet and comfortable environment. 7 Different Variations of LED Lights: Our oil diffuser has 7 different LED light colors. Press the "LIGHT" button to adjust the color of the light to your liking (steady/change color). Also, you can turn off the lights while you sleep. Of course, the essential oil diffuser can also be used as a trinket, especially to create a romantic atmosphere. Auto shut off without water: Our air diffuser has a large capacity of 500ml, and the ultrasonic dehumidifier can work for up to 10 hours. The BPA-free diffuser incorporates a water-free auto-off feature that automatically shuts off when the water runs out, making it safe to use overnight. Single product size: 158*115mm
