The model has been tested in various commercial applications including hotel lobbies, high-traffic retail stores and beauty salons. This model works equally well as a standalone and HVAC type setup.

Fully programmable 24/7, four different programs per day with custom level intensity settings down to minutes and seconds. Waterless diffusers (also known as cold air technology) transform essential oil into nano-particles without any heating which preserves the integrity of the scent. Unlike aerosols, there is no residue or messy canisters.

Scent cost savings:

This is the latest technology in scenting and the total cost of ownership is less compared to burning candles or using multiple aerosols. The initial investment in this unit typically is offset by the cost-effective technology within months, not to mention the difference in the quality of scents.

Connecting the scent machine to HVAC

All scent machine models starting with M and L in the lineup are in fact HVAC capable. Each HVAC scent diffuser comes with a metal push-in fitting that screws into the machine and a plastic tube that connects the diffuser to the HVAC air duct.

Step 1

In order for the aroma mist to carry through the air duct, the AC must be operating or the blower fan must be turned on. If the AC (or fan) is off, the aroma mist will stay in the air duct and won’t reach the intended space. If the diffuser is operating for a prolonged period of time with the AC fan being off there will be unwanted scent buildup in air ducts and could cause diffuser or air handler damage.

Step 2

HVAC setup typically requires intensity levels 10% to 15% higher compared to standalone diffuser setup. Air duct passage creates an additional volume of space through which the aroma must travel and some capacity is lost due to the extended volume of space. With a standalone setup, the aroma covers a smaller volume of space and has a slower transit time.

Step 3

Installing the air diffuser requires adequate space to accommodate your aroma diffuser and must be close to the air ducts. The ideal placement of the diffuser tube opening is after the air handler and before the first air register (please refer to the diagram above). Please ensure the air duct opening is further away from the air handler body to prevent possible interference.

Step 4

The plastic tube that connects the diffuser with the air duct should be kept as short as possible and at the near-vertical pitch. Avoid ‘sagging’ formations in the tube as this could cause oil accumulation in the lower part of the tube and possibly damage your diffuser.

Step 5

The diffuser plastic tube entering the air duct should be approximately three to four inches inside the duct and pitched at about 10% downward angle just to ease the aroma flow.

Step 6

Ensure proper insulation of the opening by using aluminum tape and secure the plastic tube to one of the hard areas to minimize any tube movement.

Step 7

The placement of the diffuser should be in a dry, clean, moist free environment nearby a proper 110V power outlet.

Yes, this diffuser operates from 100 – 240 V, the plug is for US (110) receptacles. For non-US receptacles, you would need to procure an adapter from the US to your country-specific plug type.

We work with many types of businesses and can recommend scenting solutions for your type of business based on what has worked well for similar clients e.g. pet care, medical offices, hotels, retail stores, etc. Should you need a proprietary (customer-specific) scent aroma for your business we can help you design your unique brand signature scent aroma.

Currently, we offer business diffuser leasing and fragrance oil refills for the Miami FL area only. As part of the B2B program, you will receive regular fragrance oil refills and maintenance by our trained technicians. Please contact us for a worry-free consultation.

We offer several types of commercial aroma diffusers, please contacts us for an obligation-free consultation. We would be more than happy to discuss the aroma needs for your business, we can also tailor a solution that fits your needs and budget.

With proper usage and maintenance, the expected useful life of your aroma diffuser is around four to five years. This estimate is bases on the manufacturer’s pump lifecycle expectancy of 10,000 hours and unit working seven days a week, twelve hours a day at a medium intensity level. Aroma Designers cannot independently verify or guarantee the above-mentioned estimate, this is based on information published by the manufacturer.

The consumption of fragrance oil depends on your diffuser model, intensity level, hours of operation per day and days per week. As a general principle for our residential diffuser models, at a medium intensity level, working seven days a week from 8:00AM to 20:00PM the consumption of oil is approximately 100ml per month for the Portable Mini Diffuser, 200ml for M10, 500ml for M30/L50 and 1000ml for L150. This is just an estimate and the actual consumption level can vary based on your diffuser and program settings.

Love but not smelling it as much as in the beginning

At first the scent was great when hooked up to our HVAC, but my husband and kids say they hardly smell it this past week. I’ve tried changing the settings but nothing seems to work. I smell it a little but not as much as I want to. The Manual didn’t come with instructions on what each button does so it’s pretty confusing. Help!

So Fresh and So Clean

Like walking into the spa in Turks and Caicos all over again! Thank you Aroma Designers for letting me bring vacation home.

Dear Rob,

Thank you so much for your valuable review. We are happy to hear that you enjoy Aroma Designers products and you feel vacationing in your home.

Aroma Designers Team


I shopped far and wide, finally settled on Aroma Designers. We finally installed the machine about two weeks ago and it is outstanding, will probably install one in our vacation rental next.

Our house smells wonderful, we can smell it…not too strong either, when we walk in and this has replaced all of our oil diffusers and candles. This makes our whole home smell fresh, clean and inviting.

I’d highly recommend this to anyone interested. I particularly like that they are selling from a US based business so in the event service is needed they’re here. We carefully picked our first scent…Sensation and it’s fantastic. We plan to rotate scents as we go and look forward to the next one!

Dear Kevin,

Thank you so much for your valuable detailed review. We are happy to hear about your great experience with our products.

Great little machine!

For years I used candles or those plug in scents but they only scented small areas. This machine delivers a great scent throughout the whole house via HVAC. Installation was a snap. I hung it on a wall adjacent to the HVAC unit, loaded the scent and downloaded the app. The app is great and allows full control of scent on/off times. I dialed it down to get a subtle scenting throughout the whole house and so far I have been very pleased.

Dear Paul,

Thank you for your positive feedback! We are happy to hear that you enjoy Aroma Designers products. M30 scent machine is one of our best sellers.

So far so great. I installed yesterday and was immediately mesmerized by the lovely smell flowing throughout our home. We love the Sherwood scent and can not wait to try others!!!

Thank you for your positive feedback and experience with our best seller M30 diffuser. Sherwood scent is inspired by 1 Hotel in South Beach and very likable fragrance oil.

Senselessly Incredible

We have spent a monthly $100 at Yankee Candle and even have small wax burners that we have in different areas of our home. We became frustrated and ordered the Aera scent diffuser and spent silly money on its cartridges that seemed to fragrance only our grand room.Because our home is over 4500 square feet it seemed improbable to ever get a consistent fragrance that was permeable throughout our home.Then out of frustration we kept searching and found this amazingly wonderful Aroma company and now we can smell this scent almost before we open any doors to come in the house.When I say it is well worth it that is an understatement.This will be your best investment in home fragrance ever and may we suggest Sherwood,Enigma,Black Orchid and Baccarrat Kurdjian all are as authentic as we have ever smelled in fragrances.

Ken and Stephanie –
Thank you very much for your feedback! Our classic scents ‘Enigma’ and ‘Sherwood’ as well as the designer inspired ‘Black Orchid’ and ‘Baccarat’ are all excellent choices for home scenting. Bringing positive aroma experience at home is one of our core objectives and your words inspire us to continue our work even more rigorously.
Thank you again,
Aroma Designers Team

Awesome Machine

We have always used plugin air fresheners which are expensive and only work in the room they are in. The M30 whole house HVAC system is perfect. The entire house smells great and you can set how much and for how long you want the scent to be released. Great idea and works very well. The Bluetooth setup was not bad and now I have a consistent fresh smelling home throughout the day. Thanks.

Michael Lelasher
Love it

Best decision made all year

I waited 5 years too long

I have wanted one of these for many years after moving into an older home that we just couldn't rid of that old smell. Finally pulled the trigger, have had it installed for 8 days now and have been in heaven ever since!! Super easy install into the HVAC system, I'm a 39 yr old female and did it myself. Love the scent pack it came with so you can see which ones to order without wasting your money. Enigma is my favorite so far. I read terrible things about the app for the bluetooth setup, and although not the most user friendly, never had any problems connecting via Bluetooth. If you're on the fence about this purchase, just DO IT...I promise you will not be disappointed!
