Top 6 Questions Answered on Nebulizing Diffusers

There are hundreds of essential oil diffusers to choose from on the market. A Google or Amazon search can be overwhelming; which one should you choose? The majority of diffusers available to us are ultrasonic diffusers. Nebulizing diffusers may be new to you. This article will help you understand them better and answer the top 6 questions we get on them.

I do not kid when I say that I own over a dozen different types of diffusers and have purchased many more. Why? Essential oil diffusers are not all created equal. What are the noteworthy differences between ultrasonic and nebulizing types?


  1. What is the difference between Nebulizing vs Ultrasonic Diffuser?

Ultrasonic diffusers cause powerful ultrasonic vibrations from a small metal disc. These vibrations break up the essential oils into tiny micro-sized particles then are dispersed into a fine water vapor mist. We know essential oils and water do not mix, so ultrasonic vibration is required with these units. The amount of essential oils to use should be indicated by the manufacturer's guide and the total amount of water the reservoir holds. If the manufacturer does not state how many drops to use, my general recommendation is ten drops for 400mls of water.


There are far more ultrasonic diffusers in the marketplace than nebulizers. They come in a variety of sizes and colors, some with timers, some without. Many have higher quality grade plastic parts, but not all. Please do your due diligence when performing your research. 

Potential Cons

  • Whenever you use water, and it sits for any length of time, there is a potential to grow mold and fungus. 
  • Microbial growth is not the only reason to keep your unit clean. Essential oils are potent and can erode the plastic parts. Oxidized oils also have the potential to cause respiratory irritation, so be diligent about cleanliness. 

Nebulizing diffusers are the crème de la crème method for dispersing essential oils in your home. This type of diffuser does not use water. Nebulizing diffusers atomize the oils using a series of tubes, dispersing the oils in their purest form.


As you can imagine, the nebulizing diffuser is much stronger than the ultrasonic; therefore, it is beneficial when you need a more therapeutic result. A few examples could be if someone in the home feels under the weather or is dealing with an acute condition. If you have a home with high ceilings or an open concept, a nebulizer is a better choice.   

Potential Cons

  • They can be a bit more costly than ultrasonic diffusers.

Which One is Right for You? 

If the goal is to get the best essential oil diffuser with the most significant benefits, then a nebulizing diffuser is your clear choice. In my opinion, water and oil just don’t mix!

  1. Are Nebulizing Diffusers safe? 

 Nebulizing diffusers are very safe and because they don’t use water, there is no risk of diffusing mold that is not cleaned out properly from an ultrasonic diffuser.

  1. How Nebulizing Diffusers work?

 Above the reservoir where you place your pure essential oils, there is a microtube, and on top of that, an air pump. These create a type of vacuum that pulls up the essential oil particles and disperses them into the air. The typical nebulizing diffuser has a wooden base with glass components, not plastic like an ultrasonic diffuser.

  1. How to clean a Nebulizing Diffuser?

Unlike an ultrasonic diffuser, which should be cleaned after each use, a nebulizing diffuser can be cleaned every few weeks. All you need to do is pour 25 to 30 drops of rubbing alcohol into the machine's glass reservoir and let it run for 5-10minutes. Then throw out the alcohol and let the glass attachment dry.

  1. Why Nebulizing diffusers have a timer? 

Nebulizing diffusers have a timer and usually have a few modes to allow you to customize how powerful you want your scent. Because they are potent, the timer is an automatic safety precaution to prevent you from using too much essential oil in your space.

  1. Should you use Nebulizing diffuser for a large room?
