Product details
Fragrance for the Whole Room
The AURO A900 is the largest model AATOL makes: a tall, slim cylinder in brushed metallic silver, built to stand on the floor and scent a space rather than a corner of it. It is the model for lobbies, lounges, showrooms and open-plan floors — places where scent is part of the experience rather than a personal preference.
Upward Mist, Even Diffusion
Most diffusers push scent sideways from a shelf, which means the room gets a strong zone and a weak zone. The A900 releases an upward misting column, so the fragrance enters the air above the unit and distributes through the volume as it settles.
In a lobby or a showroom this is the difference between a room that smells of something and a room that smells like the corner where the machine is.
Built to Stand on the Floor
Floor-standing is a functional choice, not just a design one. A unit at floor level is out of the sightline, out of the way of cleaning staff and guests, and it can push scent into the air at a height where it will travel. In a space with high ceilings, that matters: scent released at waist height in a six-metre room never really fills it.
10,000 mAh, and No Cable Across the Floor
The battery keeps a large room scented without a cable trailing across a marble floor — useful in a lobby where visible cable is a hazard and an eyesore. Days of everyday use per charge, with USB-C charging.
Three Intensity Modes
Low for all-day background, mid for business hours, high for events and viewings. In commercial use the discipline is to pick one mode and run intervals rather than switching to high permanently: continuous high output is how staff become nose-blind to a scent that guests still notice.
Open Oil System at 100 mL
Any AATOL 100 mL fragrance oil fits, with no cartridges and no subscription. For a hotel or a showroom choosing a signature scent, that means you can change the oil for a season or a launch without changing hardware.
Where It Belongs
Hotel lobbies, lounges, showrooms, open-plan offices, restaurants, entryways of large homes and any space where the air volume is measured in more than one room. For a single living room or a bedroom, the A700 is the better match.

Frequently Asked Questions
Can it scent a hotel lobby?
It is built for that scale — upward diffusion into a large air volume. For very large or divided spaces, commercial buyers usually run more than one unit rather than one unit at maximum output. Email info@aatol.com with your floor plan.
Does it need to be near an outlet?
It runs cordless on a 10,000 mAh battery, so no — it charges periodically over USB-C.
Is high mode for everyday use?
No. High is for events and viewings. Running high continuously is the fastest way to make staff nose-blind.
What maintenance does it need?
Refill the oil bottle. There is no water tank, so no descaling, no mould, no weekly cleaning routine.
Do you offer volume pricing for hotels?
Yes — from 10 units or 10 oil bottles. Email info@aatol.com.

Frequently asked questions
Is it really waterless?
Completely. No water tank, no wet mist, no limescale, no descaling — just pure, undiluted fragrance.
Can I use my own fragrance oils?
Yes. Every AATOL diffuser uses an open oil system: any AATOL 100 mL fragrance oil, plus most third-party fragrance oils and essential oil blends. Low to medium viscosity oils give the best mist.
How long does one refill last?
The 100 mL refill bottle lasts weeks, even in a large room — the upward misting column diffuses fragrance efficiently through big open spaces.
Is it noisy?
No — 38 dB or under, so it can stand in a lobby, lounge or showroom without being noticed.
Does it need to stay plugged in?
No. The 10,000 mAh battery runs cordless for days, and recharges over USB-C.
Where should it stand?
On the floor: the A900 is the floor-standing model in the range, designed for hotel lobbies, lounges, showrooms and other large commercial spaces.
Which fragrance should I start with?
Every diffuser includes a complimentary 10 mL hotel-signature fragrance oil, selected at random from our fresh, floral, woody and hotel-signature collections. Prefer a specific scent? Simply add a note at checkout, or browse our full fragrance range to add a 100 mL bottle.
What if I don't like it?
Every AATOL diffuser comes with a 1-year limited warranty and a 30-day money-back guarantee.
