Product details
Fragrance for the whole room. Presence for the whole space.
AURO A900 is the largest statement in the AATOL waterless collection — a tall, slim cylinder in brushed metallic silver that stands quietly in the corner and fills large rooms and open spaces with pure, undiluted scent. No water, no heat, no compromise.
Floor-standing for the biggest spaces — built to stand on the floor, the largest model in the AATOL range. Made for hotel lobbies, lounges, showrooms and other commercial spaces where scent is part of the experience.
What makes it different:
- Upward mist, even diffusion — an advanced upward misting column distributes fragrance evenly through the air for a longer-lasting, more consistent scent experience
- 100 mL refill capacity — one cartridge keeps your space scented for weeks; fewer refills, less fuss
- 10,000 mAh battery — powerful cordless performance that keeps a whole room fragrant without hunting for an outlet
- Three intensity modes — a subtle all-day whisper, a balanced everyday diffusion, or a high-output mode for maximum scent presence
- Truly waterless atomization — pure oil is cold-misted into the air, never heated or diluted, so every note arrives true
- Whisper-quiet operation — designed to disappear into your space, not interrupt it
Perfect for: living rooms, open-plan kitchens, entryways, offices, studios, and any space where you want scent to be felt, not just smelled.

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 premium 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. Intensity, schedules and modes are set in the Bluetooth app.
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?
Choose the bundle option and we will include a 100 mL AATOL fragrance oil, selected at random from our fresh, floral, woody and hotel-signature collections. Prefer a specific scent? Simply add a note at checkout.
What if I don't like it?
Every AATOL diffuser comes with a 1-year limited warranty and a 30-day money-back guarantee.
