One scent or many? One — the same Hotel Collection blend (₹299) everywhere is what makes a home smell like yours.
Running cost? Only scent: ₹299 a bottle, refills from ₹999. The machine is bought once.
2. One scent, everywhere. A single Hotel Collection blend (₹299) through the home — not a different note per room.
3. Keep it gentle. A luxury home smells inviting, never like an air freshener. Run it low.
4. Air first. Fragrance crowns clean, ventilated air; it never replaces it.
5. Budget for the refill. The machine once, then refills from ₹999 — the whole ongoing spend.

The questions everyone asks first
Almost every conversation opens the same way: what do I actually buy, and will it be too much? The honest answer to the first is that the space decides, not the price tag — you buy for the air volume of what you want scented, and the shortlist chooses itself. A single bedroom or study is small and enclosed, so a Boond at ₹799 is plenty. An open living-dining floor wants a Sukoon at ₹1,799. A large room, or one you run all day, wants the six-litre Megh at ₹3,499. And a whole flat, villa or duplex — one signature everywhere — is the waterless Vaayu at ₹11,999. That single mapping resolves most of the anxiety on its own.
The second worry — will it be overpowering? — is the right instinct, and the answer is that it should never be. The tell of a cheaply scented home is intensity; the tell of a luxurious one is restraint. Every SOSA machine runs comfortably below its maximum, and that is where it should live: felt at the door, present in the background, gone the moment you would call it strong. If a guest can name the note before they can name the room, it is turned up too high. Gentleness is not a compromise here — it is the whole point.
The money questions
The questions people are shyest about are the ones about cost, so let me be blunt about it. Good home fragrance is cheap to run and the machine is the only real outlay. There is no subscription, no cartridge racket, no fortnightly aerosol habit. You buy a diffuser once, sized to your home, and thereafter you buy scent — a Hotel Collection bottle at ₹299 or a refill from ₹999 — and on a gentle setting it lasts. Over a year, a diffuser plus a couple of refills costs a fraction of the disposables it replaces, and it smells like a home rather than a corridor.
| Your home | The pick | One-time |
|---|---|---|
| One bedroom or study | Boond + scent | ₹799 + ₹299 |
| Open living floor | Sukoon | ₹1,799 |
| Large room / all-day | Megh (6L) | ₹3,499 |
| Whole home / villa | SOSA Vaayu | ₹11,999 |
| Ongoing (any) | Scent / refills | ₹299 / from ₹999 |
Getting it right, and keeping it right
The questions that come later are about living with it well. Should each room smell different? No — one signature everywhere is what turns a house into somewhere that smells like you, and it is cheaper besides. Reeds, candles or a diffuser? Reeds are lovely and silent for a small still room, candles add warmth for an evening, and an ultrasonic or waterless diffuser is what carries a scent through a whole home — they are teammates, not rivals. Do I still open the windows? Always: scent is the layer on top of clean air, and the effect of fragrance on mood and welcome is real but moderate, so ventilation stays the base.
The last question is the wisest one people ask: how do I choose the scent? Slowly. Audition two candidates from the Hotel Collection for a fortnight each in the room you spend most time in, because a scent behaves differently at home than on a blotter and the one you love in a shop is not always the one you love at 8pm on a Tuesday. Ask the people you live with, because a signature is shared. Then commit, keep it, and change the whole home together by season if you want variety. Get those choices right and the answer to every other question takes care of itself.
The SOSA home edit
Most of this FAQ reduces to one table: size the machine to your home, choose one scent, budget for the refill. Here is the range, priced plainly.
| System | Best for | Why it works | Price |
|---|---|---|---|
| Boond | One room, a bedside table, gifting | Compact ultrasonic for a small enclosed space, or a thoughtful first gift with a scent | ₹799 |
| Sukoon | Living room, open-plan main floor | Holds a compact living area on a gentle setting; the everyday workhorse | ₹1,799 |
| Megh (6L) | Large living area, long unattended runs | Big 6-litre tank for a party-sized room or all-day running without refilling | ₹3,499 |
| SOSA Vaayu ★ | Whole home, villa, duplex — one signature | Waterless cold-air, up to ~1000m³, app + timer; one machine, one scent, every room | ₹11,999 |
| Hotel Collection scent | The signature itself | SOSA’s interpretations of the world’s finest hotel scents; audition two before you commit | ₹299 |
| Refills | The running cost | Keep the signature going; the machine is bought once, refills are the ongoing spend | from ₹999 |
Versailles
I keep a folder of the questions people send me, and the striking thing is how few there really are. Underneath the wording it is nearly always the same four: what do I buy, what will it cost, will it be too strong, and how do I choose the scent.
So I stopped answering them one at a time and wrote this. If you take only one thing from it, take the shape of the answer: a machine sized to your home, one scent, run gently, over clean air. That is the whole craft.
