Your space smells wonderful, and you don't have to think about it.
The whole room, not one corner
Covers up to 1,500 sq ft with normal ceilings: the room it's in and the rooms open to it. Put it where the air moves and the scent goes with it.
Set it once, then forget it
Use the free phone app to pick when it runs: on before you wake up, off while the house is empty, back on before guests arrive. Set your own schedule and it keeps it for you.
As light or as strong as you like
Set the intensity in the app: how many seconds it works and how many it rests. Gentle for a bedroom, fuller for a party.
Easy refills
The bottle inside holds 200 ml (7 fl oz). Open it, pour in a refill, close it. Any Aromely fragrance works.
Pure fragrance, nothing added
No water, no heat, no candles or plugs. Cold-air diffusion turns the fragrance oil into a fine dry mist, so what you smell is exactly what's in the bottle.
Put it where you like
A tabletop, a shelf or the wall (the wall kit is in the box). Small enough to move from room to room.
How it works
No water. No heat. Just the fragrance, as a fine dry mist.
The ARO 25 MAX gently blows air through the fragrance oil and sends it out as a mist so fine you can't see it. Nothing is heated or watered down, so the room smells exactly like the bottle.
Free phone app
Choose the days and hours it runs and set the intensity. Set the schedule once; it remembers it.
200 ml (7 fl oz) bottle inside
Pour in any Aromely fragrance. How long a fill lasts depends on how strong and how many hours a day you run it.
One unit, the open space
The mist drifts through the room it's in and the rooms open to it. Rooms behind closed doors need their own diffuser.
Setting it up
Setting it up takes minutes.
How to use it
Open it and fill the bottle with fragrance oil.
Plug it in and open the Aromely app.
Set the hours and the intensity.
Where to put it
Set it on a table or shelf about chest height, or hang it with the wall kit.
A diffuser fills the air in a room, not the floor. We say square feet because that's the number you know about your home, and we assume normal 8 ft ceilings. Higher ceilings mean more air to fill, so the same diffuser covers a smaller home.
See the math
1,500 sq ft × 8 ft ceiling = 12,000 cu ft of air the ARO 25 MAX can scent.

*"Comfortable fit" keeps 20% of the diffuser's capacity in reserve (our 1.2 allowance), so it doesn't have to run at its limit. It's guidance, not a guarantee. The fit helper above works this out for you.
Side by side
How the ARO 25 MAX compares with our other diffusers
Coverage is the most each can do with normal 8 ft ceilings. Prices are today's.
New to a scent? The 50 ml bottle lets you live with it first. Love it? The 150 ml is the one ARO 25 MAX owners come back for. Every Aromely fragrance comes in both sizes.
How often will I refill it?
Every installation is different. The intensity you set, how many hours a day it runs and the size of the area all change how fast the oil goes. On average, a 150 ml bottle lasts 1 to 3 months, depending on use and the size of the area. A lower intensity makes it last longer.

On a table or shelf about chest height, or on the wall with the kit in the box, pointed toward the open room. It scents the room it's in and the rooms open to it.
Which fragrance bottle should I buy with it?
If the scent is new to you, start with the 50 ml. Once you know you love it, the 150 ml lasts much longer. Both pour into the diffuser's own bottle.
How long does a bottle last?
It depends on the intensity you set, how many hours a day it runs and the size of the area. On average a 150 ml bottle lasts 1 to 3 months.
Why do you measure in square feet?
Because that's the number you know about your home. A diffuser really fills the air in a room, so we assume normal 8 ft ceilings when we say 1,500 sq ft. If your ceilings are higher, it covers less. The fit helper above does that math for you.
What if it stops working?
It's covered for one year from the day it arrives. Call 866-276-6359 or email support@aromely.com with your order number; if it needs repair or replacement we send you a prepaid shipping label.
Can I return it?
Yes. You have 30 days from delivery, and we pay the return shipping in the U.S. You're welcome to try it first. Just send it back in the same condition you received it: the original box, all the accessories, and no fragrance oil left in the tank or the hose. Fragrance bottles need to come back unopened.
For business
Several rooms, several locations, or paperwork before a purchase order?
Hotels, gyms, clinics and offices need a different setup: one unit per zone or HVAC system, fragrance by the gallon, paperwork on file. Our business team handles that.
