SpaVapor Diffuser Appearance

The SpaVapor is my workhorse diffuser, and gets daily use in my office. It plugs into the wall and sits next to my Himalayan salt lamp. The SpaVapor is about as wide as a 2-liter soda bottle, but only about half as tall. It has a plastic interior and exterior.

Using Your SpaVapor Diffuser

To use the diffuser, fill it with tap water up to the indicated line. Add up to 5 drops of essential oil.

The SpaVapor has a power button and a light button, and the systems are independent. You can run the lights without the diffuser and vice-versa. It shuts off automatically when it runs out of water or when you push the power button.

The SpaVapor diffuser is easy to clean. Learn how to clean an ultrasonic diffuser here.


The SpaVapor is great for teachers to diffuse in their classroom. It runs for 6 hours, which is the same amount of time kids are in school. Wouldn’t it be nice if the classroom smelled like oranges or peppermint instead of those icky industrial cleaners?
