Our Story / Testimonials

In 1999, inventor, Earl Sevy, approached an opportunity to develop a more durable and sleek designed cold air diffuser for a large essential oil company. Others had tried to develop a design that the company would embrace but none had been able to reach a level of quality and style that met the company’s expectations. Earl met and exceeded that expectation and landed his first order for 8000 units.

From 2000-2003, Earl’s manufacturing company was selling tens of thousands of units every year.  By 2005, Earl’s young company started the development of the most popular atomizing diffuser in the industry today; The Aroma-Ace™.  “When I launched my website in 2003, I started getting all kinds of valuable feedback from consumers about what they were looking for in their ideal diffuser. That information helped me nail down my concept and design for the Aroma-Ace™”, stated Earl. He took advantage of the local Southern Utah University that had recently purchased their first 3D printer.  This allowed Earl to rapid prototype and work together with like-minded people to develop the best atomizing diffuser in the industry.

Sure enough, in 2010, The Aroma-Ace™ Cold Air Atomizing Diffuser took the industry by storm. More of these atomizing diffusers have been sold than all of the other products combined in years prior to its release.  The Aroma-Ace™ continues to be the number one seller in the world. Earl laments, “no one person becomes successful by themselves. Never give up no matter how bad things seem to get.  And, don’t be afraid to fail”.

Since the release of the Aroma-Ace™ and its huge success, Earl Sevy has expanded his equipment and technology in order to take new products from concept to reality five times faster than before. State of the art 3D printers, molding equipment and quality controlled manufacturing facilities, allow development of innovative new products to blossom.

With his wife, DeAnn, stepping in as CEO to run the business, Earl’s main focus is on creating and developing.  The new change in CEO has brought excitement to Diffuser World. With Earl focused on new product development, many new atomizing diffusers are planned to expand the product line offering the best therapeutic benefit in diffuser technology.

Perfect Oils for Post-Op in our Surgical Center
Hello Diffuser World! This is the first time I have ever reviewed anything, but I wanted to tell you how effective your products are. I am the Perioperative Educator for St. Mary Medical Center in Bucks County, PA. We have been using aromatherapy for our surgical patients for many years. Mary Rita Lewis, RN, a pre-operative nurse, is our aromatherapy champion and expert who offers this modality to her patients. She carefully screens them for allergies and sensitivities. She is very intuitive and can immediately tell which oil or combination of oils might help each patient, and enlists their preferences too. She uses a simple technique of placing a couple of drops on a 2x2 inch gauze pad, then places that pad in a small zip lock bag and hands it to the patient. This way, the patient can open and close the bag and inhale as much or little as they want. This pouch of aromatherapy goes with the patient from the Preoperative unit, to the Recovery Room (Post Anesthesia Care Unit) and into the Postoperative area where they prepare to be discharged to home. Simple and effective! Each time we order, the orders come within two days of our order, again, simple and effective! Our favorites for our setting are: Sweet Orange, Lavender and Peppermint. Thank you for offering this product via on-line purchase and making it affordable as well. We love it! Gratefully yours, Mary Rita Lewis, RN, CAPA & Jim Gentile, RN, CPAN, CAPA Surgical Services St. Mary Medical Center 1201 Langhorne-Newtown Road Langhorne, PA 19047

Great Customer Service
Thank you very much for the fast, efficient service! I appreciate your company honoring the warranty and the quick response times. Much to my complete satisfaction. Respectfully, Hank

Excellent Customer Service
We have enjoyed using our Advanced Aromatherapy diffuser which our daughter had given us a few years ago. 
When we noticed it no longer “misted”, we were referred to Diffuser World of Enoch, Utah, to have it repaired. 
The customer service person was courteous and understanding. We mailed the diffuser to them. They replaced it and returned it to us in four daysWe highly commend Diffuser World. In fact we were so impressed that we bought a second diffuser from them. Mel

Dear friends at Diffuser World:  I just  wanted to tell you how appreciative I am to have received all the diffusers I sent you back all fixed up for FREE!!! I can’t believe it, and am not sure you should have done it. I have never bought any other diffusers, and never will, so thank you SO much.  Not very many people these days who do business like you do, and create such good products as well!  I wish you more and more success.  It has been fun watching you grow and create new things, as I have done, and I tell all my friends, and LOVE all the new things you are creating.  Bless you and your work. Pam Ritzau, Hailey, Idaho

Thank You!
My Aroma-Ace was repaired very quickly. We love it and have now purchased a second one. It is the best diffuser on the market. Your customer service is great! Eleanor, New Ulm, Texas

Outstanding Company
We've ordered several times over the years from Diffuser World, and have always been satisfied with both the products, and the service Especially our last experience with customer service was above and beyond. Matt, Austin, Texas

I love my Aroma-Ace and Your Customer Service!
Thank you so much for repairing my Aroma-Ace diffuser. What a pleasure it is to know there are still reputable companies who stand behind their products! I love my Aroma-Ace and use it daily...a great product with outstanding customer service! Joleen, Casselberry, Florida

Trust Diffuser World Nebulizers

Aroma-Whisper Heaven
I just received my new Aroma-Whisper and I already love it. I had it set up and running in 10 minutes and it is so easy to operate. It is very compact and powerful. It puts out such a fine mist that the scent is not overwhelming at all. It really is so quiet that the only sound I hear is the faintest, barely audible hiss of the mist coming out of the diffuser spout. It doesn't use much oil, either, unlike most others I have seen. I've used lots of different diffusers over the years, in a wide range of styles and prices. It's only been a few hours since set up, but I have to tell you that the Aroma-Whisper is far and away the absolute best aromatherapy diffuser I have ever used. I wish I knew others who use essential oils so that I could tell them about this diffuser, and that it is a "must have" for any serious aroma therapist. Awesome product and great customer service, packaging, and shipping. Got here in 3 days! Set it up in 10 minutes. Now I am relaxing to wonderful citrus oils. Perfect. Lesli

The Best Diffuser Out There – For My Classroom Too!
I was surfing the web one day looking for a diffuser and all I kept finding was the typical glass one and then I found the Aroma-Ace diffuser. I ordered it immediately and it is the most amazing one yet. It's easy to use, doesn't make a mess and most importantly, it doesn't waste the oils as I found the other diffusers do. I love how I can control the settings on my diffuser and the output. It is definitely well worth it and I felt the therapeutic effects immediately. I am a teacher and often use a diffuser in the classroom....but I’m always concerned about it being messy or the glass breaking----with this, my students are guaranteed a therapeutic experience as well! Priya, New York, NY

Quite Simply the BEST!
Well folks, I’m in love again! No, it’s not because its spring-----it’s because my old buddy Earl Sevy at Diffuser World has finally delivered on the promised goods after 4 years of research and development. You see, I’m a reformed aromatherapy addict who used to go through Essential Oil Diffusers like most people go through underwear. Trouble was, every diffuser design I tried was lacking in some fundamental way. Some Diffusers were too noisy, some too cumbersome with hoses and pumps, too hard to clean, too hard to switch out different Essential Oils---you get the idea. So, I finally gave up using Nebulizers due to their high maintenance and hassle and stopped aromatherapy altogether.

When Earl called me to try out his latest product the Aroma-Ace Nebulizing Diffuser, I was cautiously optimistic but excited. Diffuser World had invested nearly a quarter million dollars and 4 years of extensive research and development in order to solve all the aforementioned problems. Not only did Earl investigate all existing Diffuser designs, he also decided to manufacture all the parts himself. He fabricated all the injection molds, designed his own high-velocity pump, made the diffuser effortless to use, and most importantly, brought all the fun back to the pleasures of aromatherapy. His patent-pending quick change system is fabulous and makes switching out Essential Oils a 5 second job. His design is sleek, very user friendly, and offers the ultimate flexibility by allowing the user to control the on-off cycle through 2 control knobs. I’ve been playing with this new Diffuser for several weeks trying to get it to malfunction, but alas, it is so well built that nothing I could throw at it could even make it hiccup.

So, what do I think about the new Aroma-Ace Nebulizing Diffuser? It is quite simply the best Essential Oil Diffuser on the market today. The Aroma-Ace is incredibly well engineered and built from the best components. It works flawlessly, is an absolute pleasure to use, is simple to clean, there are no glass parts to break. The Aroma-Ace Diffuser is user friendly and adjustable, and finally….it is just a blast to use! I give it my highest recommendation and urge you to check out the Aroma-Ace Essential Oil Diffuser for yourself and see if you fall in love with Aromatherapy again just as I did.

Affiliate Program is Awesome
I have been an affiliate with Diffuser World for the past year and I love all of the products I have ordered. I have also had great successes with the Affiliate program. I have referred many of my friends through my Diffuser World Link. It is always a pleasant surprise to me when I get notified of my affiliate commissions each month. It is a bonus to get the extra money and all I had to do was put the link on my website and do a little advertising and now I am making money without having to do anything else. Thank You Diffuser World. You guys are awesome. Linda

The Aroma-Ace has Everything!
What an excellent piece of engineering! The Aroma-Ace has everything I could ask for! The built-in timer and the exceptionally wide air pressure range make it easy to regulate the amount of oil in the air for various needs in various room sizes.
I like the compact size and I REALLY like the absence of tubes and that annoying hissing sound! Oh, and the fact that the whole unit is so stable with no fragile glass parts - great! And then, there's the ease in changing oils - I don't have to try to pour oil back in a bottle and there are no gummy parts to clean!! In short, what's not to like? The features are wonderful, it works like a dream, it's sturdy, is very easily transported, the price is fair... I love it!  Jan Meredith, Jan Meredith Essentials

Couldn't be More Happy!
I received the box of diffusers yesterday and couldn't be happier with your product. I immediately put one in our living room to test and was extremely impressed. I'm going to put one in our store today with a nice light fragrance and see how they sell. I have a feeling they will sell well since we specialize in oils and organic products. Your box is very nice also. Much better than either companies I have used before. Jeanette Weber

Aroma-Ace Takes Top Honors!
What a wonderful diffuser. The sleek design is beautiful. What a brilliant way to change oils, no loss of product or danger of damaging the components. The timer and output controls are a great improvement. I will be proud to sell another of your great products. Debbie Raines, Integrity Health Enterprises LLC

All Roads Lead to Diffuser World

I once heard a saying that the rich buy the best but they only buy it once. That seemed like a pretty good strategy to me and I have been doing it that way ever since. So after an extensive internet search for the best diffuser on the market it soon became apparent that all roads lead to Diffuser World. So I called Diffuser World fully prepared to order the top rated Aroma-Pro and was invited to test and evaluate the new state of the art Aroma-Ace. I jumped at the chance mainly for the fact that it is the most efficient diffuser on the market and would eventually pay for its self. I warned Diffuser World that I am extremely discriminating, critical, and would only give a brutally honest evaluation good or bad; they said that was exactly what they wanted so here it is. The first thing I noticed was the weight, it is a small attractive all-in-one unit and I expected it to be light as a feather and was impressed when the unit was more solid and substantial. It reminds me of the way things used to be made if you don't believe me pick up my 1954 sewing machine! I have used it constantly for a week now and it has performed flawlessly. It is very easy to change oils, you can move it from room to room with one hand, it is very quiet, and I like that it doesn’t have any fragile expensive to replace glass parts. It has a comfort insert across the top which seems a little silly, I mean it would make more sense if it was a combination diffuser and garden tool but then again I guess a comfort insert is better than no comfort insert. I would and will recommend the Aroma Ace to everyone! R S Pendleton

Aroma-Ace Essential Oil Diffuser Aromatherapy System

I have been using this diffuser for four months and love it. It's fairly quiet and with the bottle attachments it's a snap to switch between oils or create your own blends. So far every bottle I have tried that is 15ml in size fits the spouts very well. I purchased the diffuser after having a stroke and wanting to try aromatherapy to deal with the anxiety and depression that followed. The Aroma-Ace took my aromatherapy to a whole new level. Buy it. You'll love it.  Stuart Greer

Aroma-Ace is By Far The Best

I have used many aromatherapy diffusers but this is by far the best. No messing with tubes and loss of pressure. Disperses essentials oils with the ability to control how much, timing on and timing off. I bought a second one because we have a large house. Great product and fast shipping. Sheri Jacobs

Aroma-Ace Travels Great and Totally Functional

I've spent $100's on other diffusers and nothing else comes close. Very sturdy, high quality construction. Awesome diffuser; My favorite by far! Pete Covatta

This is the Best Diffuser!
Silent, programmable, and an easy to attach oil bottle. Such an improvement over the noisy diffuser I had before that needed a programmable timer and had a delicate glass nebulizer that was hard to clean! Jennifer Penske

I Don’t Think Anyone Will Top This One!
I have had quite a few diffusers in the past, both inexpensive and expensive. This one is by far the best one I have ever owned! No hoses or delicate, expensive & difficult to clean glass nebulizers to worry about breaking or coming loose. No spills & no hassles! It’s super easy to use right out of the box. It’s amazingly easy to clean, and best of all you can totally control how long it stays on, how long it stays off and how much volume it puts out. I really can't say enough about how great it is. Don't think anyone will top this one! Robert Zangrillo

Aroma-Ace is a Real Winner!
This is the best diffuser I have ever used and I have used many in the years! Thank you for thinking this through in creating a brilliant diffuser that works wonders for the output of oil, that is stable, easy, travels well, easy to change oils and has a built in timer on top of all that! A real winner! Julie Chertow

Five-Star Rating!
I gave this a 5-star rating. This unit is GREAT. It blows all other diffusers away. I once bought nebulizer/cool mister diffuser, for $74.99 and within 3 weeks it didn’t work. I LOVE this unit. It’s so convenient and easy to use, plus its controls are amazing! It's a steal for this price. It's professional grade. Andy Ozfuruncu

I Love the Convenience and Automation
I love the total convenience of the Aroma-Ace! The automation of the settings makes it worry free, and it's so easy to reset whenever I choose! I use this diffuser in my healing office and now I'm diffusing EVERY DAY instead of just now and then! An-Ra-Nae Meders

This Nurse Loves the Aroma-Ace
I have received the new Aroma-Ace and am using it, I love the fact that you do not have to worry about the glass nebulizer breaking and you do not have to take anything off to clean. I am also happy with the fact you do not have to use a dropper to put the oils in the diffuser and that you just screw the bottle of oil on the unit and it has an option for how long it will run before it shuts down, then it starts up again. All in all it is really a great product. Keep up the good work. I have not found a better diffuser anywhere. Cyndy Streitz - CMT

I Have Been Waiting Nine Years for the Aroma-Ace

Thank you so much for providing for the world the BEST diffuser I have ever seen. I have been selling essential oils for over nine years and have tried about every diffuser on the market. This one is completely different from anything I have ever seen or used. This diffuser is programmable. This diffuser is more quiet than the others and it is more powerful. This diffuser is attractive and doesn’t have any delicate glass to break. This diffuser does not spill or break if it is tipped over. This diffuser kicks out the most amazing amount of essential oils. This diffuser uses a 15ml size bottle to hold the essential oil, which makes it ideal for diffusing all night long. This diffuser is just wildly different from anything on the market. Most importantly it is proudly made in the USA. I am so excited to finally get this diffuser; I have been waiting at least nine years for a diffuser that exceeds all of my needs and the needs of my clients. Thanks Earl for your efforts in giving us a diffuser that we can really be happy with. Tracy Hadley, President, Harmonious Scents

Aroma-Ace is Highly Recommended
The Aroma Ace is SOLID. It has no breakable parts, can be run on a wide variety of settings, and the fine mist it creates is, in a word, lovely. I like that I can use existing bottles of essential oils and attach them. I like that I don’t have to remove that hard-to-remove white ring at the base of the cap to each bottle in order to do so. I love that it is solid—I know it’s not going to fall over and break (it looks like R2-D2 from Star Wars). I highly recommend this particular product. Deb Waldron

Aroma-Ace Essential Oil Diffuser Aromatherapy System
The Aroma-Ace ranks #1 with me. The ease of operation and the effectiveness of this diffuser are second to none. The best new feature for me is the ease of attaching oil bottle. It's like set it and forget it! The aroma in my home and place of business is wonderful. I get a lot of comments. Efrain Valentine

Essential Oil Company Floracopeia, Inc. Loves the Aroma-Ace

We are an essential oil company and sell many of Diffuser World's diffusers every year. There are many characteristics about the Aroma-Ace that we enjoy. The timers are wonderful and insure a perfectly timed, consistent diffusion of essential oils all day long. The two bottles give us the ability to change from one oil to another easily during the day without having to stop and clean out the unit." Laurel Brown, General Manager, Floracopeia, Inc

The Aroma-Ace is a Wonderful Product
I am a Holistic Health Practitioner and Aromatherapist and this product is wonderful for dispensing the scent of healing essential oils. Small yet mighty, the Aroma-Ace gets the aroma into the air to help with healing and cleansing of a room! I had been looking to purchase an oil diffuser and this was just the right and reasonable price range I was looking for. It’s wonderful that come comes with two atomizers to work with and change out quickly when needed. I recommend this product to anyone who is a beginner or seasoned practitioner or anyone who wants to bring aromatherapy healing into lives! Karen J Reid

The Best Diffuser for Aromatherapy Lovers!

I’ve tried all in the search of the Spa-like-feeling in my house. This is it! Love it! The controls are a great feature, the size is perfect, easy to handle and change the oils. And the best, made in the USA. Great purchase! Ycardiff

Best Diffuser

Having the ability to control the on time and off time is worth the extra money. I love too that by controlling the output you can use this as aromatherapy or more saturated output when sickness is in the house. I started with a diffuser that was either plugged in our not - this was inconvenient for night time use as it would just run constant until the oils were gone. With this diffuser you can control the use of oils more. I highly recommend this product and would purchase it again if something happened to mine. Karriel

Awesome Product – Aroma-Ace
It met my expectations. I would recommend this product to anyone who is into essential oils, Able to use it throughout the house with different oils. Thank you. Junebug

Awesome Diffuser!
I can't say enough how awesome I think this Advanced Aromatherapy Essential Oil Diffuser is. It is easy to set up and use, you simply take the cover off the scent you wish to use and screw on the atomizer (assuming that there is no dropper insert in the bottle - in that case you would have to remove it first) and place it into the grooves and give a little twist. If you want to mix scents they give you an empty bottle in which to do that. Not to mention that you get two atomizers and two empty bottles for ease of switching between scents. The room you have it in instantly fills with the scent that you attach to it, which you can control the strength of the smell with the dial. My room is big at 14 x 24, and it even wafts through to other rooms in the house. The dial settings are nice and easy to use as well. You can set it to run as long as you want on one dial and to have breaks by setting the off dial to shut off for a period of time. The only downfall...if it has to be worded that way...is the sound. I personally don't mind it, but it sounds like a fish tank aerator. I will never have to buy a room scent ever again. This is all you will ever need. Love This! J9M1

Excellent Diffuser
I plugged the diffuser in the day we got it and have used it since. It works perfectly and I am able to use 15 ml bottles of thieves and other essential oils including Aura Cacia. In a quiet room it seems a little noisy, but at normal TV levels, I don't notice it. It uses essential oil pretty efficiently. I notice the pleasant scent on my entire first floor. I’m very happy with this purchase. Buzz Bray

Great Car Diffuser
I am pleased with this product. It is nice to drive in this hectic town with a sense of relaxation! Love it. Carol
