Why use a Nebulizing Scent Diffuser over Ultrasonic Diffuser?

When scent is diffused through nebulization, a process that breaks down fragrance oil into a very fine dry mist leaving no residue it preserves the intention behind our aroma and essential oil blends. This leaves their olfactive and therapeutic powers intact without diluting the oil in water, heating it or adding solvent to it. The result is a subtle scent that remains consistent day in and day out.

The Basics

The AromaPro™ commercial fragrance diffuser stands freely or can conveniently be mounted to a wall. This ambient scent machine also easily connects to HVAC for easy and discrete business ambient scenting. The AromaPro™ uses cold-air diffusion technology to release nanoparticles into the air that leave behind no residue. This technology preserves the olfactive and therapeutic benefits of our essential and aroma oils while creating a clean a consistent ambient scent without heat, evaporation, or diluting the oils in water or alcohol. The scent intensity is easily controlled through an external dial for simple and easy scenting.

AromaTech’s™ commercial fragrance diffusers increase your health and well being by releasing nanoparticles and purify the air. Our ambient scent machines are ideal for creating an emotional connection with your customers, while inspiring a unique brand identity with scent marketing.

FAQ – AromaPro™

Please see our extended FAQs section for extensive information on all of our diffusers, aroma oils, essential oils, and subscription plans. Here are some of the most popular questions.

Q: What size room can AromaPro™ handle?

The AromaPro™ is fully adjustable for different size areas. It is most effective in spaces from 100 to 4,000 square feet (10 to 400 square meters). Depending on the essential or aroma oil you use it may cover more area since some oils are more potent then others. When connected to HVAC, coverage may increase. Ideal for scenting large spaces such as living rooms, large bedrooms, office space or even an entire home, AromaPro™ is the most powerful and discrete diffuser on the market.

Q: Where can I place the AromaPro™?

You must place the AromaPro™ on a flat surface where it can take full advantage of the natural airflow in the space. If placing on the table top or a shelf, make sure it doesn’t tip. Alternatively you can wall mount it or connect to the HVAC. If wall mounting the AromaPro™, make sure it is secured properly and is at least 6 feet off the ground and 20″ from the ceiling. Refer to the User Manual for more details and how to connect to HVAC (air conditioning and heating system)

Q: Do I need to adjust AromaPro™?

Yes! AromaPro™ is a very powerful device that can handle small and very large spaces. If it is set too high for the room size, it can cause discomfort for some people. Adjusting scent intensity is easy. Simply touch the up and down button on the device to adjust from level 1 (min) to level 20 (max). Start at level 1 and work your way up if needed.

Q: How strong should I make the scent?

Remember, less is more. The AromaPro™ allows you to get rid of bad odours and create a unique ambience with small amounts of scent. Unlike other air fresheners, the AromaPro™ can be adjusted with a simple touch. Human nose gets used to scent very fast, so if you don’t smell the scent anymore that doesn’t mean it’s not there. Simply leave the scented area and re-enter with a fresh nose to get a better feel of how strong it is.

Q: What is the capacity of the AromaPro™ bottle?

The AromaPro™ uses a 500 ml bottle. The fragrance diffuser is designed to only take AromaTech™ bottle specific to the diffuser.

Q: How long does the essential oil last in the bottle?

The AromaPro™ uses a 500 ml bottle of essential or aroma oil that will last 1 month with daily usage running about 12 hours a day. To preserve the essential oil, we highly recommend using the internal 24/7 timer and set it up so that the diffuser doesn’t run at night time. Depending on the essential oil you are using that time may increase or decrease. Some essential oils diffuse a lot faster due to their consistency and viscosity.

Q: What is the average oil consumption of the AromaPro™?

Oil consumption strongly depends on the essential or aroma oil used. Essential oils diffuse faster then aroma oils. Average oil consumption ranges from 1 ml. – 2 ml. per hour.

Q: What if my unit does not turn on?

Check to make sure the power adaptor is properly plugged into the DC power jack and the electrical source. If hours of operation timer is set incorrectly and you are trying to diffuse during the time that the machine is programmed to be off the AromaPro™ will not scent. Refer to the User Manual for more details.

Q: How do I unlock the LCD display if it is locked and I can’t control the device?

AromaPro’s™ intuitive timer is designed to lock itself (shut off) after 10 seconds if not in use. To unlock the display simply press and hold the SET button for 5 seconds.

Q: What if my unit does not scent or there is almost no scent coming out?

Check first that there is an aroma oil in the bottle and the bottle is screwed in straight and snug. If there is fragrance in the bottle but you still don’t smell anything then either the device is in rest or pause mode, turned off, or the diffuser core is clogged and needs cleaning. Please see “Care & Maintenance” instructions.

Q: How do I connect the AromaPro™ to the HVAC (air conditioning system)?

Depending on the HVAC set up of your home and amount of air handlers that service your entire home, choose the air handler that covers the most area. Refer to the below diagram.

  1. Drill a 6 mm hole in the air supply duct.
  2. Make sure to drill a 6 mm hole before the duct splits to different areas of the house.
  3. The AromaPro™ comes with the air tube and an HVAC adaptor. Screw in the HVAC adaptor (brass fitting) into the top of the AromaPro™ diffuser outlet.
  4. Keep the air tube length between 10 – 20 inches.
  5. Make sure the tube is always straight and not kinked, or has air pockets.
  6. Wall mount the AromaPro™ or stand it up on a shelf near the air duct where you will be connecting it to.
  7. Insert the air tube from the AromaPro™ to the air duct.
  8. Insert the tube with the airflow not against it.
  9. Seal it with HVAC tape.
  10. Start up the AromaPro™ and set your desired intensity level from 1-20.

Q: Will the AromaPro™ cover my entire house?

It can, but it depends on how big your house is and how many air handlers you have in your home. If you have more then 1 air handler you will require and additional AromaPro™.

Q: What if my house is larger then 4,000 square feet?

In this case we recommend switching up to the Air Stream Single or Duo. It’s a very powerful HVAC scent machine that is capable of scenting spaces up to 15,000 square feet Depending on the Air Stream it can hold one or two 4 litre oil drums so oil refilling is required only once a year. See AromaTech™ diffuser section for more details on the Air Stream Single/Duo, or simply contact us

Q: What type of oils can I put in my home diffuser?

Use only AromaTech™ diffuser blends; other blends and oils may contain base oils that could result in clogging the device. Many single note essential oils should not be used in the diffuser. Single note essential oils may have a thick or heavy consistency that can clog the diffuser and cause it to stop diffusing scent. AromaTech™ diffuser blends have been carefully blended to be effective for you, and safe and easy to use in your cold-air diffuser.

Q: Is AromaPro safe to use with children and pets?

Yes. When used as directed and only with AromaTech™ essential and aroma oil blends, AromaPro™ is the safest cold-air diffuser available. Make sure to request SDS if you require more info about the oil being diffused.

Q: How does AromaPro™ differ from aerosol and ultrasonic diffuser?

Aerosol sprays diffuser very large particles that drop to the ground the moment they are sprayed, providing very high concentrations just in the area they were sprayed. The scent effect is very short and can’t be controlled. Ultrasonic diffusers use water and vibration to diffuse very tiny amounts of essential and aroma oils. With the AromaPro™, there is no diluting with water or other carrier oils required. The scent particles diffused suspend for several hours providing the most subtle and comfortable scented environment. The AromaPro™ creates, maintains and evenly provides a perfectly balanced scented environment continuously and in low dosage without alcohol, water, propellants or other harmful VOCs.

Q: Is AromaPro™ Diffuser Eco-Friendly?

AromaTech diffusers are the most Eco-friendly products on the market. Unlike aerosols, the AromaPro™ uses no propellants, phthalates and produces no harmful volatile organic compounds (VOCs). Unlike many air fresheners, AromaPro™ uses no ethanol or similar solvent to enhance the evaporation of essential and aroma oils.

Q: Warranty and Support?

All products designed by AromaTech™ come with a 1 year limited warranty. If you have any questions or issues simply call 1-888-276-6245 or email us at and we will be happy to assist you.

Worth the investment!

I had been thinking about purchasing the Aromapro for a year. Did not know if I wanted to spend that kind of money on fragrancing my home of 4500 sq. feet. I decided to do it on Black Friday because they were having a sale. Upon it being delivered, everything about the box it came in to the actual diffuser itself is impressive. This machine is like nothing I have ever used to get my house smelling like a resort. I was very impressed by its preformance so far. If your thinking about getting the Aromopro to scent your home, DO IT!!!!!!!!!! I DO NOT think you will regret it. Throw away all the plug ins and reed diffusers you have bought because they are garbage compared to this! I think of all the money I have spent over the years trying to get my house smelling great and it was ALL a waste. Should have bought the Aromopro years ago!!!!!!!!!!!!

Amazing product

Absolutely amazing my whole house smells incredible. Highly recommend this product

Good Experience.

Extremely helpful staff. Got our order to us OVERNIGHT as we were opening in days! Thanks again Aromatech!

If you’ve discovered the benefits of using aromatherapy at work to increase productivity and sales, reduce stress, or influence buyer behavior, great! If you’re still deciding whether it’s right for your business, there are some things to consider before making your final choices. One thing you may be wondering is whether essential or aroma oils are the best option. Let’s take a look at the differences between the two and why pure essential oils are not necessarily your best bet in a work environment.

As people start to learn about the world of aromatherapy, they quickly find that there are numerous types of oils on the market that claim to offer a variety of results. There’s certainly no shortage of debate on this topic. The truth is that essential and aroma oils have a lot in common, but they also have some fundamental differences.


Understanding essential oils

Pure, genuine essential oils are distilled from plants including flowers, roots, herbs, and more; these oils are not diluted with carrier oils. Pure essential oils can be quite expensive, and their fragrances can be quite potent – as can their medicinal properties. These oils (and the plants they come from) contain allelochemicals, which are chemicals that have a range of effects on the human body. These effects can be good or bad depending on the plant. Therefore, it’s essential to become familiar with the essential oils you use and how to use them safely. The people who use essential oils often for their benefits report that they offer many health benefits including anxiety relief, skin and hair softening, pain relief enhanced overall well-being and more.


However, pure, undiluted essential oils also have some drawbacks. First of all, they can be incredibly pricey. Few people or businesses have the budget to use essential oils exclusively meaning that aroma oils are usually the best option for a scent marketing scenario. Aroma oils are essential oil blends, or part essential oils and part carrier oils combined with other natural or synthetic aromatic ingredients. They still smell fantastic and offer many of the same benefits, but they are much more budget-friendly than their pure counterparts.

Another potential problem with essential oils is that their scent and quality can vary depending on several factors such as growing conditions and plant matter. They can also vary by region. That makes it difficult for producers to churn out consistent products. These slight variations may not matter much for the casual user, but for businesses using them in products or scent marketing, it can pose a significant problem.
