This diffuser works by Ultrasonic diffusion to keep all of the essential oil properties.
Does not create a steady stream of mist like most regular diffusers but 13-60 second bursts of diffused essential oil.
Comes with 1 empty refillable glass cartridge that you fill with your favourite Essential Oil. Great for people that work on laptops at offices, allergy sufferers, people travelling or anyone that would like to cleanse the air around them while near a USB port.
*** Refill Packs for USB Diffuser are also available ***
