NOW Ultrasonic USB Essential Oil Diffuser with LED Lights

The NOW Ultrasonic USB Essential Oil Diffuser combines convenient aromatherapy with compact, modern design. This white tabletop diffuser uses high-frequency ultrasonic vibrations to turn water and essential oils into a fine, cool mist without heat. Because no heat is involved, it offers a practical way to diffuse aromatic oils while avoiding hot surfaces and open flames.

Designed for home, office, dorm or travel use, the diffuser connects to a laptop, power adapter or other compatible USB port using the included 40-inch USB cable. Its 70 mL water reservoir provides up to four hours of continuous mist, while the automatic shutoff feature turns the unit off when the water runs out.

Rotating red, green and blue LED lights create a calming visual atmosphere and can be switched off when preferred. The compact diffuser is extremely quiet, BPA-free and easy to clean, making it suitable for desks, bedrooms and smaller living spaces. It is made with recycled plastic and includes a one-year manufacturer warranty for added purchase confidence.
