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™ scent machine stands freely or can conveniently be mounted to a wall. This diffuser also has the option to connect to your home HVAC system, allowing you to scent your entire home with ease. The AromaPro™ uses cold-air diffusion technology to release nanoparticles into the air that leave behind no residue. This technology preserves the integrity of our aroma and essential oils, so you can receive the maximum olfactive and therapeutic benefits, without heat, evaporation, or diluting the oils in water or alcohol. The scent intensity is easily controlled through an external dial. Pair the AromaPro™ in a scent bundle to enjoy some of AromaTech’s™ most popular 100% Essential and Aroma Oil Blends.

AromaTech™ scent diffusers increase your health and well being by releasing nanoparticles and purify the air. Our fragrance diffusers are ideal for creating a unique and inviting ambience in your home and getting the maximum health benefits from your essential oils.

Unique Technology

The fragrance is diffused through nebulization (cold-air diffusion), a process that breaks down essential and aroma oils into a very fine dry mist. This preserves the intention and integrity behind our oils, while maximizing their olfactive and therapeutic powers, without diluting in water, solvent, or using heat.

This patented nebulizing technology, combined with an essential and aroma oil blend, produces nanoparticles that suspend in the air for several hours providing the benefits of therapeutic use essential oils or simply enhancing the ambience in you home.

    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!

    Great Product

    Very happy with this product. Easy to install. I am giving one star less because it should come with a bottle of flagrance.


    I have been using the aromatech pro for over a week. So far, we are very happy with the system.

    What’s the Difference between Essential and Aroma Oils?


    You may hear the terms “essential oil” and “aroma oil” used interchangeably, but this isn’t entirely accurate. Essential oils and aroma oils have some fundamental differences – and some key similarities. These two types of oil are chemically different, have different properties, and are priced differently, but they can often be used for the same purposes.


    Essential oils

    Essential oils are extracted from plants using a process known as distillation, most commonly using water or steam. This process uses many parts of the plant, including the flowers, stems, bark, and roots. The finished product is the highly concentrated essential oil, which has the same properties and scent characteristics as the original plant. That does include the smell, but it also includes other elements such as the plant’s healing and other abilities. It’s easy to see why essential oils are so popular: you get a highly potent form of the plant or herb you want to use – and you need a much smaller quantity to achieve the same effects.


    Aroma Oils

    A good natural aroma oil is simply an essential oil blended with other natural ingredients such as carrier oils and other essential oils to create a perfectly scented oil that can be used in a diffuser. Why not just use pure essential oils? There are several reasons:

    • Essential oils are often very strong and potent; their smell can be overpowering and intolerable for sensitive individuals.
    • They are much more expensive in their pure form.
    • Blending essential oils with carrier and other aroma oils can result in a much more pleasant, subtle scent that can be used throughout the day to create an amiable, homely

    For these reasons, essential oils are blended with other natural ingredients to form aroma oils with the perfect scent and intensity.


    What to look for

    There are countless aroma oils on the market, but you shouldn’t buy just any. Keep in mind that aroma oils are not all created equal. Some are made with synthetic chemicals and lab-created fragrance compounds. While these can be cheaper, they are also lower-quality when it comes to their scent and their impact on your health and mood.

    That’s why, at AromaTech, we provide the highest-quality aroma oils and diffuser blends. We make our oils with premium raw and natural ingredients, combined with pure essential oils containing no GMOs, animal products, parabens, glycols, phthalates, artificial colours or other additives, or any other harmful chemicals.

    With our diffusers, there’s no need to buy expensive essential oils and dilute them with carrier oils or another substance to scent your home. Instead, choose from our ready-to-use aroma oil blends to create the scenting experience you desire. Our aroma oils are safe for your family, pets, and home and suitable for use in any of our cold-air or ultrasonic diffusers to create your perfect ambience.
