You can also take it to the gym, yoga studio, or use outdoors with insect repellent blends to keep pesky bugs from biting.

  • How does a waterless essential oil diffuser work?

  • What are the benefits of a waterless diffuser?

    A waterless air diffuser offers many unique benefits that aren’t available from other types of diffusers. First, as the name implies, waterless diffusers don’t require any water or measuring a water-to-oil ratio. Simply attach a bottle of your favorite essential oil or essential oil blend and the device will diffuse automatically. 

    Additionally, the vapor from a waterless essential oil diffuser provides more therapeutic benefits because the oil isn’t watered down or heated. A waterless oil diffuser like Aviva disperses oils into the air in their purest form for greater absorption and stronger aromas.

  • What is the difference between a waterless diffuser and other types of diffusers?

    There are four main types of essential oil diffusers: waterless diffusers, steam diffusers, ultrasonic diffusers, and passive diffusers. 

    Waterless diffusers nebulize essential oils, which means they use air pressure to vaporize the oil instead of using heat or water. Steam diffusers heat water and oil to create a scented steam. Ultrasonic diffusers use high frequency soundwaves to vibrate oil and water into vapor. Finally, passive diffusers are non-electronic objects made from ceramic or other porous materials. Passive diffusers allow essential oil aromas to slowly, gently fill a space as the oils absorb and activate in the exposed air.

  • What essential oils can I use with a waterless oil aroma diffuser?

    You can use almost any essential oil in a waterless aroma diffuser. Some of our favorites include Lavender, Lemon, and Patchouli, as well as blends like Meadow Breeze, Tranquility, and Counting Sheep. With the Aviva Waterless Diffuser, you can also get creative and use the included bottle to make your own blends. (Note: We do not recommend diffusing essential oil blends that include a carrier oil such as FCO or Jojoba.)
