We Have No Collection. We Only Compose.
Every diffusion company sells a machine and a fragrance from their library — the same one they sell to hotels in forty other cities, usually on a subscription. We have no library. No catalogue, no house collection, no numbered range. Every fragrance is composed from nothing by Johanna Monange, our Founder and Master Perfumer, for one property alone — then runs from your lobby into your bathroom, your spa and the candle a guest carries home.
Statement A machine can be replaced. A scent that belongs to you cannot be copied.

In their words
What Our Clients Say
The signature now carries from the arrival hall through every public space, and the reed diffusers hold it in the quieter corners where the machines do not reach.Resorts World Sentosa
Our lobby scent arrives before the concierge does. The tailored reed diffuser lets guests take that exact impression back to their own hall.The Laurus
Olive blossom and sea salt, diffused through the whole property. The candle is now the piece guests ask for at reception before they leave.Hotel Luura
Horizon was composed for us alone. The wardrobe ceramic carries it into the suites without a single machine in the room.Raffles Sentosa
One fragrance, four objects — candle, room spray, reed diffuser and the gift set. Guests recognise the hotel with their eyes closed.The Point Brisbane
Four fragrances, one story of place. The discovery set has become our most requested VIP welcome, and each one traces back to the scent in the club lounge.The Ritz-Carlton
Hearthmere and Bramblenook were written for this estate. The diffusion holds them through the halls; the boxed set lets a guest keep them.Rockliffe Hall
The room is 1920s Osaka and the scent had to belong to it. Nothing from a catalogue would have done. The candle sells out every season.Mimi Kakushi
Sea air, neroli and warm wood, diffused across the terrace and the interior alike. The reed diffuser keeps it steady where the breeze takes over.La Cantine
The diffusion carries the signature through the lobby and lift lobbies. The candle finishes the suite, and it is the object guests photograph.Kimpton Sanya
Cedar, leather and sandalwood — the smell of arriving somewhere warm after the cold. The candle became our signature retail piece in one season.Caravan by Faraway
A century of Pacific Heights, translated into one scent. The diffuser set lets a guest keep the hotel in their own hallway.Hotel Drisco
At our volume, consistency is everything. The system runs across zones on different schedules and the fragrance never varies.Marina Bay Sands
Clean formulation was the condition, not a preference. Vegan, free from CMR and phthalates — and a scent our patients comment on daily.Solmedica Clinics
The treatment rooms carry a softer expression of the house signature. The candle extends the ritual once the guest is home.Raffles Spa
Beyond the machine
Hotel Candles, Reed Diffusers & Retail Fragrance
Where a scenting company stops at the lobby, a perfumery continues. Hotel candles, reed diffusers, room fragrance, pillow mists, wardrobe ceramics, welcome sprays and a retail collection — all in the signature already filling your spaces, and all ready for a guest to take home. A complete 360° hotel scent ecosystem: lobby and corridors, guest rooms and suites, spa and wellness, restaurants and public bathrooms, refillable bathroom amenities, and the hotel retail collection a guest buys on the way out. One olfactory identity rather than a scent that stops at the door — and equally suited to luxury resorts, branded residences, spas and private clinics. Full range and quotation on request.

Tell us your spaces and we return a configuration with a purchase cost and an annual running cost — then a conversation with Johanna Monange, our Founder and Master Perfumer, about the fragrance itself. No subscription, no monthly fee, no obligation. Your formula is owned solely by your property, never reused, never offered elsewhere. Room count and lobby size are what let us size the system, so we can answer with numbers rather than another question.
Frequently asked
Hotel Scent Diffusion, Signature Scent & Olfactory Branding
What is hotel scent marketing, and does it work?
Hotel scent marketing — also called olfactory branding or sensory branding — is the practice of giving a property its own fragrance and diffusing it consistently across the guest journey. Scent is processed in the same region of the brain as memory, which is why a signature is recalled long after a logo is forgotten. Done properly it lifts brand recall, emotional attachment and perceived luxury, and opens a retail line in candles, reed diffusers and room fragrance.
How do hotels create a signature scent?
With a perfumer, not a scent consultant working from a library. At Maison 21G Paris the olfactive brief covers your heritage, your region, your values and what a guest should feel on arrival. Johanna Monange, our Founder and Master Perfumer, then composes across three rounds with at least five distinct directions per round. The finished formula is your olfactory identity, owned solely by your property under contract.
How do hotel HVAC scent diffusers work?
The AirElite M1600 HVAC scent diffuser connects to your existing air handling and releases a dry cold-air micro-mist of pure fragrance oil into the duct, which carries it evenly through the served spaces. There is no heat, no water and no residue — only pressurised air, so the fragrance reaches the guest exactly as the perfumer composed it.
What is the best scent diffuser for a hotel lobby?
For most lobbies, the M1600 HVAC scent machine, covering 600 to 1,000 m². Where there is no suitable HVAC access, the standalone Tower M1200 covers 300 to 400 m² at under 50 dBA — quiet enough for a hotel lobby at night. For lounges and meeting rooms of 50 to 100 m² the M150, and for public bathrooms the wall-mounted M100.
How much does hotel scenting cost per month?
There are no monthly fees at any point. You buy the commercial scent diffuser once — $1,000 for the M1600, $500 for the Tower M1200, $300 for the M150, $100 for the M100 — and then only the fragrance refill, from $180 to $250 per litre depending on volume, lasting roughly six weeks per machine. That is the entire running cost, and it is the sharpest difference between us and a subscription scenting company.
How many scent diffusers does my property need?
It depends on square metreage, ceiling height, air movement and how many zones you want scented. As a guide: one M1600 per 600 to 1,000 m² of HVAC-served space, one Tower M1200 per 300 to 400 m² standalone, one M150 per 50 to 100 m² lounge or meeting room. Send your floor plans and we will size it properly and return a quotation.
Do you have a scent collection we can choose from?
No, and that is deliberate. Maison 21G has no library, no house collection and no numbered range. Every bespoke hotel fragrance is composed from nothing by our Founder and Master Perfumer for one property alone, then owned by that property permanently and exclusively under contract — never reused, replicated or offered to another hotel.
How is Maison 21G different from ScentAir, Air Aroma, Prolitec or Aroma360?
They are technology companies; we are a perfumery. Their hardware is good and their libraries are extensive, but the fragrance is chosen from a catalogue available to every hotel that calls them, usually on a monthly subscription. Ours is composed for you by a Master Perfumer, the machine is bought once with no service fee, and the same signature continues into your amenities, spa collection and retail fragrance — a complete hotel scent solution rather than a diffusion contract.
Can the same scent run across diffusion, amenities and retail?
Yes, and this is the whole point of a 360° scent ecosystem. One olfactory identity runs from lobby diffusion through corridors and guest rooms into refillable bathroom amenities, pillow mists, spa collections, candles, reed diffusers and room fragrance a guest can buy and take home. No scent marketing company can offer that, because they do not formulate cosmetics.
Do you work with boutique and independent hotels?
Yes. Low MOQ hotel scenting is one of our strengths — a boutique hotel can start with a single Tower M1200 in the lobby and a bespoke fragrance, then add scented objects as the programme grows. We work equally with five-star groups, luxury resorts, branded residences, spas and wellness properties, and private clinics.
Are the systems silent, and safe in every environment?
The Tower M1200 runs at under 50 dBA, below normal conversation; HVAC units sit within your plant, so guests hear nothing. Our compositions are vegan, cruelty-free and PETA-approved, free from CMR substances, phthalates, parabens, preservatives, colourants and GMOs, with a high content of natural essential oils. They are gentle enough for nurseries, veterinary and medical spaces, spas and wellness environments.
Can you support a hotel pre-opening or refurbishment?
Yes, and our lead times suit it: four to six weeks for fragrance development, then commissioning alongside your programme. We work directly with procurement, purchasing and project teams, respond to tender and RFP documentation, and supply hotels across Singapore, Dubai, the UAE, Saudi Arabia, Europe, the United Kingdom, the United States and Australia.
