Diffusers are one of the best ways to make use of the therapeutic value of essential oils. The AromaFuse diffuser is an ultrasonic oil diffuser. I have discussed the different kinds of essential oil diffusers in a previous post. Read it HERE. The ultrasonic diffusers do not use heat, which destroys the molecules of the oils. Instead, they use water that is broken up into a mist by an ultrasonic vibrating disc. These types of diffusers are the most popular and the price is fairly reasonable. So let’s take a look at my favorite diffuser thus far – THE AROMAFUSE by Plant Therapy.

How To Use It

This diffuser is very easy to use:

1. Remove the cover.
2. Add water in the reservoir to the water mark.
3. Add drops of oil, depending on preference of strength.
4. Replace the cover.
5. Connect the power cord.
6. Press power button and choose desired setting.

AromaFuse Diffuser


The AromaFuse stands 4.3″ tall and 6.8″ wide. As you can see from the picture, it has angled legs that lift it up about an inch off the surface.  This diffuser comes in 3 colors, Rose Gold, Wood-grain Brown, and Pearl White.  It has a very modern and stylish look and is easy to use. The plastic parts in the AromaFuse are BPA-free food-grade plastics and the diffuser tank is coated to protect against erosion by essential oils.  It has a one year limited warranty from the time purchase.


This diffuser has 5 timer settings.

  • Press once for continuous until it runs out of water, approximately 6-10 hours.
  • Press twice to run for 2 hours and turns off automatically
  • Press three times to diffuse at 15 sec on/30 sec off until water runs out.
  • Press four times to diffuse at 15 min on/30 min off until water runs out.
  • Press five times to diffuse at 30 min on/30 min off until water runs out.

This diffuser also has a Light setting. When the diffuser starts, the LED light comes on. Press the button once to dim the light. Press the button twice to turn the light off.

The AromaFuse has a large 380 ml water reservoir that can give up to 10 hours of continuous diffusion. It covers an area of more than 500 square feet.

Why Buy This Product?

Essential oils have so many therapeutic properties that are beneficial to all of us. They can be used for many conditions. Anything from anxiety and depression to respiratory conditions, such as, sinus, colds, and asthma. They can be used to treat pain, for wrinkles, scars and wounds. Oils can also be great air fresheners, too.

The AromaFuse can be used along with essential oils to help relieve a lot of these conditions. When the molecules of the oils are misted into the air, they are inhaled to help give relief.

What I Like About This Diffuser

I like Plant Therapy’s AromaFuse  mostly for the fact that there are more choices of how long the diffuser can run. I like to have mine run all day, so having it 30 minutes on and 30 minutes off is perfect.  Although, now that I’ve been using it a while, I actually let it go 15 minutes on and 30 minutes off.  So, that might be more perfect!  It seems to run for at least 24 hours using this setting.  I do like the style of this diffuser, with the angles legs.

Lights are not why I buy a diffuser. I like the AromaFuse diffuser because there is only one light option, either on or off, and it’s dimmable. Most of the time, I leave the light off on my diffuser. I just use it for the benefit of the oils. I like that the diffuser has a one-year limited warranty, which is great!

What I don’t like about the diffuser

Right now I can’t think of anything I don’t like about this AromaFuse diffuser.

Where Can These Be Purchased?

The AromaFuse is sold by Plant Therapy and the purchase price is $54.95.  It comes in Rose Gold, Wood-Grain Brown, and Pearl While.   You can purchase the AromaFuse HERE. They do have great sales, so you also, can watch when it goes on sale and purchase it then.


OilLife Ultrasonic DiffuserTHE LUX SAVANNAH

If there’s something about the AromaFuse you don’t like,  I have found two other diffusers that might peak your interest.  The first one is the Lux Savannah ultrasonic diffuser from OilLife.

This diffuser is made from black metal and stands 10″ tall and 6″ wide.  The water tank will hold 300 ml of water and the diffuser covers 1000 sq feet.  It has 4 mist settings:  continuous, intermittent, alternating, and off.   The Lux Savannah will run for 12 continuous hours or 34 hrs alternating.  There is a timer option of 2, 4, or 6 hours.

If you like a diffuser with lights, you may like this one.  It has 4 modes:  warm white, rotating colors, fixed, and off.  You can purchase this for $69.99 HERE.


Here is a diffuser that looks like a lot of fun and the kids just might enjoy it.  It’s the OceanMist from Your Oil Tools.  This one has a 6 hr continuous mist and 24 hrs low intermittent mist.  YourOilToolsultrasonicdiffuserThe water tank holds 300 ml of water and will diffuse a medium size room.  There are rotating colors that gives an aquarium effect to the diffuser with the vegetation and sea animals. The kids will just love watching the creatures and vegetation come alive.  You can find this one HERE under Lifestyles/Ultrasonic Diffusers for $39.99.

My Final Words

Which ultrasonic oil diffuser do you like?  My personal choice is the AromaFuse diffuser because it has several timer settings, and because of the one-year warranty. The ratings on this diffuser are pretty good, with an average of 4.5 stars on with 564 reviews and has 4 stars on with 83 reviews.

The other two ultrasonic oil diffusers are sufficient alternatives.  It just depends on what your preference is and what you like in a diffuser.

Diffusers are great to help keep you healthy and to improve your life.  If you are using a diffuser, that’s awesome!  If you are looking to buy one, I hope this review of the AromaFuse and its alternatives has given you some information to help you in your decision.

As always, thanks for reading!

  1. Thanks for sharing this article. I am not a direct user myself but my girlfriend is hooked on the oils and we have a diffuser in every bathroom and in the bedroom. Coming to bed at night with the diffusor running is really nice. With some tranquillizing meditation music in the background and the mobile phones in another room, the setting is perfect for sleeping.

    1. Lars,
      Sounds like your girlfriend has the right idea. My bet she is using lavender essential oil in the diffuser. Lavender is an awesome oil. It just puts you in that relaxation mode. That’s what we use to help us sleep. It’s great that you are getting the benefits of your girlfriend using essential oils. Thanks for sharing!!!

  2. I enjoyed reading your post about these diffusers. I use one that I purchased from Young Living Oils where I have a friend who sells oils. I love the diffuser, but I really don’t know how it works, except that it puts a mist up in the air! I like the sounds of the diffusers you mentioned and they seem to have a lot more versatility in that they will run for hours instead of an hour…
    Thank you!

    1. Karin,
      I’m glad to hear you use a diffuser already. It sounds like you have an ultrasonic with a disc that vibrates, shaking up the oil molecules. It’s really interesting how it works. These diffusers have the choice of running just a short amount of time or longer. How long does yours run? Just an hour?

      That’s the thing I like the most about these, especially the AromaFuse. They can run all day. You just need to make sure the right amount of essential oils are put in. I typically use from 10-12 drops for all day. Thanks for reading!

  3. I absolutely love aromatherapy essential oils as I know how great they are for healing all sorts of conditions. I work in a Herbal Apothecary and we have a huge selection of essential oils and also we have a a diffuser on the go all the time. This means I get to try and test all the oils and have come to realise their power. If I feel tired I put something zingy in like lemon or grapefruit and it works like a charm to wake me up.

    I love the diffusers in your post as they not only do the great job of diffusing healing oils into the air but they also look stylish and pretty. It’s reminded me that I really want to purchase one for my own home; something that I have wanted to do for a while.

    1. Stefanie,
      That sounds like a really awesome place to work. I am into the natural ways of healing. We use herbs and, of course, use a lot of essential oils. So you have discovered the power of essential oils. I love it. For sure lemon and grapefruit give you that pick me up. They have so many other great benefits, too. Check out my posts about lemon essential oil and grapefruit essential oil.

      I’m really surprised you don’t have a diffuser for home use, then you would get those awesome benefits all day long and even when you’re not working. Let me know if you end up getting one and what kind!

  4. Great article on diffusors…..Got a question? I have really bad allergies and sinus issues. What would recommend to use? Does what you promote address these types of issues? Please get back to me….thanks

    1. Terry,
      I’ll answer you with a bit of history. My husband, Perrie, has been suffering with allergies for years and we were spending so much money on OTC meds. He discovered essential oils about 4 years ago to see if they could help him. Within the first year of using essential oils, he no longer had to take those OTC meds and we are saving money, because you use such a small amount of oils.

      We use eucalyptus and peppermint essential oils in the diffuser. Here’s my post on peppermint oil and here is my eucalyptus oil post. These will give you more information about these oils. How much you use depends on the size of the diffuser.

      Along with the diffuser, we both use personal inhalers that have eucalyptus oil and peppermint oil in them. They are portable, so you can take them anywhere. You can buy the inhalers and add the oils to them. Here is where you can get the inhalers. They come in different colors. Also, here is a link to our inhaler recipe that we use.

      I hope this helps you. We just know by experience that it has helped us. I have sinus problems and both of these help to relieve the condition. Please, if you have anymore questions feel free to send me an email or comment.
