Description Frequently Asked Questions

This mini, portable USB diffuser has it all: ultrasonic technology, power adaptability, and decorative design. Plug the unit directly into your computer so that the ultrasonic diffusion can silently diffuse water and your favorite essential oil. Or, use the 48” extension cord (included) to set the unit away from the computer. The diffuser offers 2 timer settings for controlling mist output, allowing the water and oil reservoir to last up to 6 hours. A decorative top with embossed floral design comes in different colors, making this unit attractive as well as functional. Need extra wicks? Click here to get more!

Enjoying it July 5, 2017
Reviewer: JoAnn from Cameron Park, CA United States  
When do I change the filter? I've used it daily, M-F for one cycle, for two weeks and it's barely puffing steam. I use the every 10 seconds setting.

Lots of oil...wick?? May 1, 2017
Reviewer: Kristen Biltz from Batesville, IN United States  
It takes more oil than I would have thought for such a small diffuser and I wasn't expecting the wick. Seems to be okay though. For the cost of replacement wicks, I probably will try to find a more convenient car diffuser.
