Which question separates the good quotations from the bad? Coverage, because it is where the exaggeration lives. Any figure in square feet has silently assumed a ceiling height, and a double-height boutique eats capacity fast - you scent volume, not floor area. A supplier quoting cubic metres has told you something checkable; one quoting square feet has told you a story. The SOSA Vaayu is rated to 1000m³, which works out at roughly 2,000-3,000 sq ft at ordinary retail ceiling heights.
Where does SOSA fail its own checklist? On question seven. SOSA does not currently sell cold-air refill oil as a separate line item. A Vaayu at ₹11,999 ships with 4 x 100ml, the 400ml tank runs 90+ days a fill, and beyond that supplied quantity there is no published refill SKU today. Ask us about continuity before you standardise on the machine, and hold every other supplier to the same question - a refill you cannot price is a running cost you cannot budget.

Facts verified 5 September 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, described by the manufacturer as approximately 2,000-3,000 sq ft, with adjustable intensity, a 400ml refillable tank lasting 90+ days a fill depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB at 5W, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification, which are electrical and compliance marks and not medical approvals. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering roughly 270-320 sq ft and is supplied with three 15ml fragrances; the water-based Hotel Collection (₹299 / ₹999 / ₹1,799) is an ultrasonic fragrance and is not a refill for a waterless cold-air machine. SOSA reed diffusers are alcohol-free and phthalate-free, with 50ml lasting about 6-8 weeks and 130ml about 14-18 weeks. Cold-air refill oil for the Vaayu is not currently sold separately - the machine ships with 400ml included and further refills should be confirmed with SOSA. Warranty, annual maintenance, installation and bulk terms are not published and should be confirmed before ordering. Ambient scent is an interior and hospitality decision: it makes no clinical, therapeutic or wellbeing claim, it works alongside proper ventilation, cleaning and infection control and is never a substitute for any of them, it is never used to mask another smell, and no claim is made that fragrance influences a patient's decision or any commercial outcome. Clinical areas including procedure, post-procedure and photography rooms are left unscented, and the treating clinician's judgement overrides any scenting plan in their own room. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation. Prices and availability are subject to change - see the live product pages.
Every scenting quotation you receive will be built to be hard to compare with the last one. The way out is a fixed list of seven questions asked of everybody in the same words - and a list that only flatters the person who wrote it is not a list, so the seventh question is the one this supplier does not currently answer well.
Quick answers — read this first
What should I actually check? Seven things, in this order. Coverage in cubic metres rather than square feet; waterless or water-based; how finely the timer can be set; whether the intensity can be locked; the noise rating in dB; the mounting options; and whether refill oil is a published, purchasable line. Ask every supplier all seven in the same words and the quotations become comparable for the first time. Notice that none of the seven is about the fragrance, which is the part you can change later and which every supplier will want to talk about first.Which question separates the good quotations from the bad? Coverage, because it is where the exaggeration lives. Any figure in square feet has silently assumed a ceiling height, and a double-height boutique eats capacity fast - you scent volume, not floor area. A supplier quoting cubic metres has told you something checkable; one quoting square feet has told you a story. The SOSA Vaayu is rated to 1000m³, which works out at roughly 2,000-3,000 sq ft at ordinary retail ceiling heights.

A Vaayu at ₹11,999 ships with 4 x 100ml, the 400ml tank runs 90+ days a fill, and beyond that supplied quantity there is no published refill SKU today. Ask us about continuity before you standardise on the machine, and hold every other supplier to the same question - a refill you cannot price is a running cost you cannot budget.
The short answer
Short answer: seven things: coverage quoted in cubic metres rather than square feet, waterless or water-based, how finely the timer can be set, whether intensity can be locked, the noise rating in dB, the mounting options, and whether refill oil is a published purchasable line. Ask every supplier the same seven in the same words. On the last one, SOSA does not currently sell cold-air refill oil separately.
The pick: one SOSA Vaayu (₹11,999) if the answers you need are 1000m³, waterless, timed, locked, under 38dB and wall or HVAC mountable - and one SOSA Sukoon (₹1,899) if the store is a single room under about 750 sq ft.
Next step: send us the two or three quotations you are holding along with your carpet area and ceiling height, and we will tell you which questions each one has left unanswered - Ask for a retail scenting plan.

Straight answer
What should I look for when buying a commercial scent machine for a watch store?
Seven questions, asked of every supplier in the same words. I would rather hand you the list than a brochure. One: coverage in cubic metres. This is where the exaggeration lives: a square-foot figure has silently assumed a ceiling height, and you scent volume rather than floor area, so a double-height showroom eats capacity fast. The SOSA Vaayu is rated to 1000m³, roughly 2,000-3,000 sq ft at ordinary retail heights. Ask what height any square-foot number assumed, and watch what happens. Two: waterless or water-based. A cold-air nebuliser atomises undiluted oil with no water and no heat, so it adds no moisture to the room and leaves no residue on surfaces; an ultrasonic unit works by misting water. That is a factual difference between machines, not a claim about your stock; whether room conditions matter to a piece is a question for the brands you carry. Three: timer granularity. Ask what intervals exist and whether the machine can be off when the shutters are down. The Vaayu offers 1h/4h/8h/24h timers through a Bluetooth app and onboard buttons, plus auto-stop. Four: can the level be locked? This matters more in retail than anywhere else, because a shop floor has many hands and the level only ever drifts upward - somebody in the room since morning stops noticing and turns it up for the evening. A key-lock holds one decision in place. Ask also that anyone can switch the machine off in seconds; locking the level is not locking the off switch, and a customer who mentions sensitivity is answered by turning it down, never by defending it. Five: the noise rating, in dB. A watch sale is a quiet conversation. The Vaayu runs under 38dB, and a supplier with no dB figure has not measured it. Six: mounting. Freestanding, wall, or into the air handling? Mounting is how one machine reaches an entrance area, a showroom and a closed lounge - the difference between a product you place and one the building distributes. Seven: refill availability - and here I fail my own list. Ask for the refill SKU, its size, its price and its lead time in writing. SOSA does not currently sell cold-air refill oil as a separate line item. A Vaayu ships with 4 x 100ml, the 400ml tank runs 90+ days a fill, and that is the supply as it stands; confirm continuity with us before you standardise across more than one store. Two things belong on no checklist. A promised result - no one can promise that ambient scent moves footfall, dwell, conversion or spend, and a supplier offering you a figure is selling - and an assumed commercial term, since bulk pricing, GST and corporate invoicing, AMC, warranty, installation, minimum order and multi-site rollout support are all unpublished at SOSA. Fragrance is also never a way to cover another smell, so no machine on your shortlist fixes a fit-out or corridor problem. And below about 750 sq ft no machine passes the first question: buy a SOSA Sukoon at ₹1,899 instead. Ask for a retail scenting plan and send us the quotations you are holding.
Seven questions for every supplier: coverage in m³, waterless or water-based, timer granularity, a lockable level, a dB figure, mounting options, and a published refill SKU. SOSA answers six and fails the seventh - there is no separate cold-air refill oil today.
The machine these answers describe is one SOSA Vaayu - 1000m³, waterless, 1h/4h/8h/24h timers, key-lock, under 38dB, freestanding or wall and HVAC mountable, CE, RoHS and SGS certified. ₹11,999. Under 750 sq ft no machine is the right answer and the Sukoon at ₹1,899 is.

Here is what the seven answers look like when they are written down plainly, including the one that is a gap rather than a specification.
1,500 sq ft and up, or several volumes of air
SOSA Vaayu
1000m³ coverage, waterless cold-air nebulisation of undiluted oil, 1h/4h/8h/24h timers by app and onboard button, adjustable intensity, key-lock, auto-stop, under 38dB, DC 12V/1A at 5W, 165 x 80.5 x 215mm, 0.9kg, black or white, freestanding or wall and HVAC mount. CE, RoHS and SGS certified. 400ml tank, 90+ days a fill.
From ₹11,999
Under about 750 sq ft - the machine is the wrong question
SOSA Sukoon
Ultrasonic cool-mist diffuser covering roughly 270-320 sq ft, supplied with three 15ml fragrances. Water-based, which is a straightforward fact about the unit rather than a fault. At ₹1,899 it is the correct purchase for a single trading room, and its consumables are published and easy to plan.
From ₹1,899
The three questions suppliers dislike
Four of the seven are answered happily by everybody. These three are the ones that produce a pause, and the pause is the information.
1
Ask for cubic metres and hold the line
A square-foot rating has assumed a ceiling height it did not tell you about
Coverage is the single most inflated figure in this trade, and the inflation is hidden in geometry rather than in dishonesty. A machine rated for 2,500 sq ft at a nine-foot ceiling is covering a very different building at fourteen feet, and luxury retail is full of high and double-height rooms. Ask for the cubic figure and the assumed height together, then measure your own. The Vaayu's 1000m³ works out at roughly 2,000-3,000 sq ft at ordinary retail heights, and in a boutique with a double-height entrance it will cover less floor than that arithmetic suggests - which is worth knowing before you buy rather than after.
Tip: Measure ceiling height in the tallest part of the store, not at the till.
2
Ask what can be locked, and what cannot
In retail the control question matters more than the coverage question
A shop floor has many hands. The level in a store never drifts downward: somebody stops noticing it around four in the afternoon and turns it up, and the next person does the same on a different day. Ask whether intensity can be locked, whether the schedule can be locked, and what happens after a power cut - does it return to your setting or to the factory one? Then ask the opposite question: can anybody on the floor switch it off in seconds without asking permission? Both answers should be yes. A machine that cannot be locked will be renegotiated weekly, and a machine that cannot be stopped instantly is wrong for a room with customers in it.
Tip: Set the level for the advisor who breathes it nine hours a day. If the team says it is too much, it is too much.
3
Ask for the refill SKU in writing - including from me
SOSA does not currently sell cold-air refill oil separately, and you should know that now
The seventh question is the one that catches this supplier. Ask any manufacturer for the refill product code, the bottle size, the price and the lead time, in writing, before the machine goes on an order. Here is SOSA's honest position: a Vaayu ships with 4 x 100ml of hotel-inspired oil, the 400ml tank runs 90+ days a fill, and there is no separate cold-air refill line published today. The water-based Hotel Collection oils are for ultrasonic diffusers only and are never a Vaayu refill, whatever the shared fragrance names suggest. Confirm continuity with us in writing before you standardise, especially across several stores.
Tip: A running cost you cannot price is a running cost you cannot budget. Ask before you order, not after.
The SOSA principle
A buyer's checklist is only worth carrying if it can catch the person who wrote it, and the seventh question on this one catches SOSA: there is no separate cold-air refill oil today.
Six good answers and one disclosed gap is more useful to a buyer than seven ticks from someone selling.
The seven-question checklist
Print this, ask every supplier the same seven in the same words, and write their answers in the same column widths. The differences will do the rest.
The SOSA plan
The seven questions, and how SOSA answers each one
| The question | What to do |
|---|---|
|
1. Coverage in cubic metres?
|
1000m³, about 2,000-3,000 sq ft at ordinary ceiling heights. Ask every supplier what height their square-foot figure assumed. |
|
2. Waterless or water-based?
|
Waterless cold-air nebulisation of undiluted oil, no water and no heat - a fact about the machine, not a claim about stock. |
|
3. How finely can it be timed?
|
1h/4h/8h/24h by Bluetooth app and onboard button, plus auto-stop, so it can be off when the shutters are down. |
|
4. Can the level be locked?
|
Yes - adjustable intensity behind a key-lock. And anyone on the floor can still switch it off in seconds. |
|
5. What is the dB rating?
|
Under 38dB. If a supplier has no figure at all, they have not measured it. |
|
6. What are the mounting options?
|
Freestanding, wall-mounted, or mounted into the air handling. 165 x 80.5 x 215mm, 0.9kg, 5W. |
|
7. Is refill oil a published line?
|
Not at SOSA today. 4 x 100ml supplied, 400ml running 90+ days a fill, and continuity must be confirmed with us in writing. |
If the checklist has left you with a budget question rather than a hardware one, the whole range is set out as arithmetic in how much a luxury retail store should budget for ambient scenting. And if you have not yet settled whether a machine is the right category at all, the three-way against reeds and room sprays is in reed diffusers, room sprays or professional scenting. SOSA is independent and not affiliated with any hotel.
Seven questions, asked of everybody
SOSA Vaayu ₹11,999 - 1000m³, waterless, timed, key-locked, under 38dB, and one refill question we answer honestly.
Ask me for the refill product code and I will tell you there is not one yet. Ask the next supplier the same question and see whether you get a code or a paragraph.

Why these seven and not others
Every question is checkable, and none is about the fragrance
The SOSA specification and what is not published
Two machines answer this checklist for watch retail, and which is right for you is decided by carpet area and ceiling height rather than by feature count. Cold-air refill oil is not currently sold separately, so the 4 x 100ml supplied with a Vaayu is the supply today, the 400ml tank runs 90+ days a fill, and continuity must be confirmed with SOSA in writing before you standardise on the machine. Bulk or corporate pricing, GST and corporate invoicing, AMC, warranty terms, installation, delivery timing, minimum order quantities, spare parts and multi-site rollout support are likewise not published and should be confirmed with us directly rather than assumed from any proposal. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

Ask all seven of every supplier, and treat a missing answer as an answer. Ambient scent here is a presentation decision like lighting, seating or case layout; it is never used to cover or neutralise another smell, and no machine on any shortlist fixes a fit-out, carpet or corridor problem. And plainly: no one can promise that ambient scent moves footfall, dwell, conversion or spend, so a percentage attached to a quotation tells you about the supplier rather than about the machine. Ask for a retail scenting plan before you spend anything.

A note from Sonal
I wrote this list because I got tired of watching retailers compare three quotations that had been deliberately built not to line up. One gives coverage in square feet, another in cubic metres, a third in a room count. One mentions a timer without saying what intervals. None of them mentions noise. By the time an owner has normalised all that, they are exhausted and they buy from whoever called most recently.
The seven questions are chosen because each has a checkable answer and none of them is about the fragrance. Fragrance is the part everybody wants to discuss and the part you can change in an afternoon. Coverage, control, noise, mounting and refills are the parts you live with for years, and they are exactly the parts a good salesperson will move past quickly. Ask them in the same words every time and write the answers side by side; the gaps announce themselves.
And then there is question seven, which I have to fail today. SOSA does not sell cold-air refill oil as a separate item, so what arrives in the box - four hundred millilitres, ninety days or more a fill - is the supply as it stands, and you should confirm continuity with us before you standardise on the machine. Everything else: Vaayu ₹11,999 from 1,500 sq ft, Sukoon ₹1,899 below 750, and no bulk pricing, AMC, warranty schedule or installation programme published, so ask rather than assume. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What should I look for when buying a commercial scent machine for a watch store?
Seven things, asked of every supplier in the same words: coverage quoted in cubic metres rather than square feet, whether it is waterless or water-based, how finely the timer can be set, whether the intensity can be locked, the noise rating in dB, the mounting options, and whether refill oil is a published purchasable line. None of the seven is about the fragrance, which is the part you can change later.
Why does coverage need to be quoted in cubic metres?
Because you scent volume rather than floor area, and any square-foot figure has silently assumed a ceiling height. A machine rated for 2,500 sq ft at nine feet is covering a very different building at fourteen, and luxury retail is full of high and double-height rooms. A SOSA Vaayu is rated to 1000 cubic metres, roughly 2,000 to 3,000 sq ft at ordinary retail heights. Ask every supplier what height their number assumed.
Why does a key-lock matter in a shop?
Because the level in a store never drifts downward. Somebody who has been on the floor since morning stops registering the fragrance and turns it up for the evening, and the next person repeats it on another day, so within a month the store is louder than anyone chose. A key-lock holds one decision in place. Ask the opposite question too - anyone on the floor should still be able to switch the machine off in seconds without permission.
Can I buy refill oil for the SOSA Vaayu separately?
Not at present, and this is the question on which SOSA fails its own checklist. The machine ships with 4 x 100ml of hotel-inspired oil, the 400ml tank runs 90 or more days a fill, and there is no separate cold-air refill line published today. The water-based Hotel Collection oils are for ultrasonic diffusers only and are never a Vaayu refill. Confirm continuity with SOSA in writing before standardising on the machine.
Should a quotation include a projected increase in sales or footfall?
No, and a quotation that includes one tells you something about the supplier. No one can promise that ambient scent moves footfall, dwell time, conversion or spend, SOSA has run no research that would support a figure, and there is no honest way to separate ambient scent from lighting, layout, service and price. Judge machines on coverage, control, noise, mounting and refills - all of which are checkable.
Seven questions - and one honest gap
SOSA — Clinic Scenting for luxury watch boutiques and premium retail
The SOSA Vaayu (₹11,999) answers six of the seven: 1000m³, waterless, 1h/4h/8h/24h timers, key-lock, under 38dB, and freestanding, wall or HVAC mounting. On the seventh, cold-air refill oil is not a published line today - confirm continuity with us before you standardise. Below about 750 sq ft, a Sukoon at ₹1,899.
