Ultrasonic USB Diffuser (50ml)

Ultrasonic diffusers use electronic frequencies to create ultrasonic vibrations that break essential oils into tiny microparticles, dispersing the oil in a fine mist without any heat. As there is little or no heat involved, the therapeutic qualities of the essential oils are better preserved.

Enjoy the pure and healing scents of your essential oils in your car rides with this practical and compact 55ml ultrasonic aroma diffuser. Have peace of mind that the diffuser's tank is made with high-grade BPA free plastic that will not be corroded over time by contact with essential oils. 

Features: This compact USB diffuser is perfect for small areas especially in the car and at the cubicle workspace. It works quietly with a good mist output and its compact size makes it portable and convenient for travel.

No manual switching off is required - when the water is used up, the diffuser will automatically power off.
