Being white or black, it will harmonize with any décor. Includes one 15mL bottle of dōTERRA® On Guard® essential oil.

Advanced Cold Air Diffusion Technology

Using a Nebulizer diffuser method, it is considered the best for realizing the full therapeutic benefits of the essential oils as it uses the cold air diffusion system. It does not heat the oil and therefore, the oil preserves its pureness. It works immediately when the unit is turned on into the room’s ambient air. The way it works is the cold air pump pulls the air up into a tube and then blows the air over the surface of the oil using the atomizer at the top. The liquid is then changed into fine droplets that the atomizer disperses into the air as a micro-fine mist. Because of its fast and effective performance, spa professionals, hair salons, boutiques, including offices and homes use this diffuser.

Micro-fine Vapor Enriches Air Quality

From the time the aromatherapy essential oil is converted into micro-fine vapors, the oil is diffused into the room. The droplets of oil appear in the form of mist and spread is diffused into the air across the room; therefore, there is no spillage or waste, and no mess to clean up.

The vaporized essential oil being at room temperature stays in its potent state and releases your favorite essential oil effects. In the absence of heating, there is no chance the oil will break down so its quality will not be altered. The dōTERRA® Aroma Ace allows the oil in its pure form to be dependable thus producing the healing properties of the essential oils. Your box will have two atomizers, and two essential oil bottles that came with the diffuser (no essential oils included).

Built-in ON/OFF Timer Prevents Over Saturation of the Air

For its quick functioning, this diffuser releases the desired amount of essential oil within a short time. A built-in switch allows you to maintain the saturation level at the desired intensity. The timer is also built-in and is the result of advanced technology that effectively maintains the correct time duration that the diffuser should operate. With the atomizer’s design and being directly connected to the oil, the diffuser works quickly. The three different control functions are time and intensity where the “on” mode allows the timer to run for 15-20 minutes; the “off” mode allows the unit to be off from 15-20 minutes then the timer interval repeats. Therefore, you will have 15-20 minutes on and 15-20 minutes off then back on. The diffuser additionally has a “volume” control for the distance you want it to spray.

How Useful Is It?

The dōTERRA® Aroma Ace is useful! What’s more, this diffuser comes with a second glass bottle to allow other users to take pleasure in their own blend of oils. The fine droplets of oil in the form of mist remain suspended in the atmosphere for a long time with their authentic oil benefits intact. The micro particles infiltrate the air in your room undamaged and complete in their composition to release their active components for hours into your home, spa, salon, or office atmosphere.

    I would like to know how to mix oils the doterra Ace diffuser

    1. Melissa

      Hi Floyd,

      I am not an aromatherapist and know nothing about that topic. I suggest you go to the Internet and research “how to blend oils.” There is a lot of information out there and there are good books too.

    You should research each essential oil you like and also the bennifits of essential oils each of yoir favorites mixes well with. It is VERY important to be sure you spend yoir momey on high quality essential oils that are eiter organic certified or wild crefted (please- if you purchase oils that habe been created from plants that are harvested using chemicals while they grow- you will be inhaling all of the pesticides and chemicals used where the plant was originally grown). I am a soap artisan and choose to do this BECAUSE most of the population is washing there bodoes with detergent NOT soap… a n d they do not realize the harmful impacts. You can reach me on Facebook if you would like, search ‘ Victoria Starr tucson’ amd look for tje angle wings. Choose wisely… Best of luck to you…

      Hi Victoria,

      We just don’t live in a perfect world, do we? We have researched essential oils and discuss those that are organically grown without pesticides. Even rain has acid in it and we can do nothing about it. As for soap, I like Olay products to get away from detergents. Maybe we should go back to the old days and use lye soap. LOL Typos forgiven; it’s hard to type when on the phone—next time turn the speaker on.

      Best regards,

    I bought this a couple years ago. I was happy with it at first. The tubes get gunky and it no longer works, I have tried cleaning it by soaking it in soapy water but it did not work. I can’t figure out how to solve this problem.

    1. Melissa

      Hi Liz,

      You bought what a couple of years ago? The tubes can be soaked in hot detergent water, or put alcohol in the unit and let it run for 20 minutes, then rinse. If this doesn’t help clean the tube, contact the manufacturer because it should be under warranty, but maybe not for 2 years. I have no problem with “gunk” when I clean my diffusers every few weeks.


  5. Mom to Many aka Doc Mom

    I am looking for dual purpose. Is there a unit that I can use for essential oils and also use for diffusing stuff like magnesium oil and water based substances such as colloidal silver, H2O2 and baking soda solution? If not, this unit sounds best for oils. What might be suggested for the other bulk water based solutions to diffuse into the air like a personal nebulizer but needed in larger quantities to benefit all in the room? Thank you.

    1. Melissa

      Hi Mom to Many,

      The nebulizers listed here are for essential oils. Your situation would need a different type of nebulizer and you can read it here.

      Good luck and hope this helps.
