Founder Diaries · Large-Space Scenting · Four Contexts
Villa — strong but conditional. Only if the ground floor is genuinely one open volume. Rooms behind doors still need reeds from ₹749.
Airbnb — conditional on how many turnovers you run. One listing: almost never. Several a week across a large property: possibly. And nobody can promise scent moves a rating.
Single home — weakest case. One room, or a flat with doors that close, is a Sukoon at ₹1,899 — ₹11,999 ÷ ₹1,899 ≈ 6.3 times less.
Sukoon₹1,899This is the variable nobody thinks about until they have lost control of a room. In a shop, someone on the evening shift decides it is too strong and turns it off; a week later it has been off for six days and the space has no identity. In a rental, a guest investigates the unfamiliar device on the console. The Vaayu's key-lock exists precisely for that, and it is the single feature that most justifies the price gap in a commercial setting — not because the machine is stronger, but because the setting you chose is the setting that persists. Scheduling does the same job in time rather than in access: 1h, 4h, 8h and 24h, with auto-stop, so the building's fragrance is a policy rather than a habit somebody has to remember. In your own home, none of that is worth much. You are the authority, and a remote-controlled Sukoon at ₹1,899 gives you all the governance you need.

SOSA Vaayu specifications (verified from the live product page, August 2026): ₹11,999 (the product page displays a rounded ₹12,000). Waterless cold-air nebulisation — pressurised air atomises undiluted fragrance oil into a dry nano-mist; no water, no heat, residue-free. Coverage up to 1000m³, about 2,000–3,000 sq ft. 400ml refillable tank, 90+ days per fill at a mid intensity setting. Bluetooth app plus onboard buttons, 1h / 4h / 8h / 24h timers, adjustable mist intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. 165 × 80.5 × 215 mm, 0.9 kg, black or white. Freestanding or wall / HVAC mount. CE, RoHS and SGS certified. Ships with four SOSA Hotel Collection fragrances at 100ml each (400ml in total) in one of three combos chosen at checkout. SOSA does not currently sell a separate Vaayu refill oil; the 400ml supplied in the box is the fragrance available at the time of writing, and buyers who need long-term supply should confirm current refill availability with SOSA before purchasing. The cold-air oil supplied with the Vaayu is a different product from the water-based Hotel Collection sold for ultrasonic machines (15ml ₹299 · 100ml ₹999 · 300ml ₹1,799), which must not be used in a Vaayu despite sharing scent names. Other SOSA machines: Boond 300ml ₹899 (~150 sq ft) · Sukoon 500ml ₹1,899 (270–320 sq ft) · Megh 6L ₹3,499 (~215 sq ft — a runtime and humidity machine, not a coverage upgrade) · Aangan ₹25,999 (~8,000–10,000 sq ft) · Meenar ₹38,500 (12,000–18,000 sq ft) · Safar car diffuser ₹3,999. Reed diffusers 50ml ₹749–₹849 (6–8 weeks) · 130ml ₹1,249–₹1,349 (14–18 weeks) · duo sets ₹1,498–₹1,598 · oil-only refills 300ml ₹2,399 / 500ml ₹3,499. Runtime, consumption and coverage figures are manufacturer specifications and vary with intensity setting, run hours, ceiling height, ventilation and season; any per-month or per-day figure in this guide is arithmetic on those specifications, not a measurement. Electricity costs vary by state tariff. No claim is made that scenting affects ratings, reviews, bookings, occupancy, revenue, health, mood or air quality. Free shipping above ₹499. A portion of every order supports girl-child education through Nanhi Kali. Prices subject to change — see the live product pages.
The same machine, at the same ₹11,999, is an obvious purchase in one building and an indulgence in another — and the deciding factor is rarely square footage. It is who is in the room, who controls the settings, and how much attention the setup can realistically be given. A business buys governance: one scent, on a schedule, that staff cannot change. A villa buys reach across a volume no bottle can cross. A host with several listings buys turnover time. And a single household, in a flat, with one room that disappoints them, is buying the least of the four — which is why this page ranks the contexts honestly rather than answering yes four times.
Quick answers — read this first
Business — strongest case. Scheduling, key-lock and one consistent identity across a space staff do not control. Vaayu ₹11,999, up to 1000m³.Villa — strong but conditional. Only if the ground floor is genuinely one open volume. Rooms behind doors still need reeds from ₹749.
Airbnb — conditional on how many turnovers you run. One listing: almost never. Several a week across a large property: possibly. And nobody can promise scent moves a rating.
Single home — weakest case. One room, or a flat with doors that close, is a Sukoon at ₹1,899 — ₹11,999 ÷ ₹1,899 ≈ 6.3 times less.
The short answer
Short answer: a Vaayu is most defensible in a commercial space, where a single controlled scent across a large open volume is an operational requirement rather than a preference; next in a villa whose common floor is genuinely one connected volume of several hundred cubic metres; next for a host running frequent turnovers across a large property; and least in an ordinary home, where the problem is usually one room, a closed door or a timing preference that ₹1,899 solves.
The mechanism: cold-air nebulisation atomises undiluted oil into a dry nano-mist under pressure, so the fragrance is airborne before the room has to do anything with it. That buys reach across connected volume and, through 1h/4h/8h/24h timers with a key-lock, governance over when a building smells of something and who can change it. Those two goods — reach and governance — are worth different amounts in each of the four contexts, which is why the answer differs.

Straight answer
Is a SOSA Vaayu right for my building?
1. A business — the strongest case. A showroom, clinic waiting area, salon, boutique or office reception is a large open volume with no internal doors, occupied by people who did not choose the scent and staff who should not be adjusting it. The 1h/4h/8h/24h timers and the key-lock are the product, and up to 1000m³ is the reach. ₹11,999.
2. A villa — strong, with one condition. Buy it only if the common floor is genuinely one connected volume of roughly 250m³ or more. If it is a hall, a sitting room and a dining room with doors between them, three Sukoons at ₹1,899 × 3 = ₹5,697 is cheaper and independently controllable.
3. An Airbnb — it depends on turnover count, not on listing count. One flat you clean yourself: no. Several turnovers a week across a large property where nobody wants to be flipping reeds at handover: possibly, and the scheduling is what you are paying for.
4. And on Airbnb, one thing said plainly: nobody can promise that scenting a property moves a rating, a review score, a booking rate, an occupancy figure or a nightly rate. There is no data for any of it. What is real and describable is the guest's experience of arrival — the first ninety seconds after the door opens. Buy it for that or do not buy it.
5. A single home — the weakest case, and the commonest enquiry. A flat with internal doors is not one large space, and one living room is rarely more than 100–150m³ against a 1000m³ rating. ₹11,999 ÷ ₹1,899 ≈ 6.3, and the Sukoon covers 270–320 sq ft with a remote and timers.
6. In every context, rooms behind closed doors are a separate problem. No machine crosses a shut door. Reed diffusers at ₹749–₹849 for 6–8 weeks, or ₹1,249–₹1,349 for 14–18 weeks, are the answer in all four buildings.
7. Ask about fragrance supply before you order, in every context. SOSA does not currently sell a separate Vaayu refill oil; 400ml ships in the box, specified at 90+ days a fill. This matters most to the business buyer, who is the one running it hardest.

TL;DR: business — yes, for scheduling, key-lock and one identity across an open floor. Villa — yes if the common floor is genuinely one volume above roughly 250m³. Airbnb — only with frequent turnovers on a large property, and never on a promise about ratings. Single home — almost never; buy a ₹1,899 Sukoon and reeds from ₹749.
Built for the context where control is the point
SOSA Vaayu · waterless cold-air nebuliser ₹11,999
Up to 1000m³ — about 2,000 to 3,000 sq ft depending on ceiling height — from a 400ml refillable tank specified at 90+ days per fill at a mid intensity setting. The features that decide the business and villa cases are not the reach but the governance: 1h, 4h, 8h and 24h timers, adjustable mist intensity, auto-stop and a key-lock so nobody standing near it can change what the building smells of. Bluetooth app plus onboard buttons, under 38 dB, DC 12V/1A at 5W, 0.9 kg, freestanding or wall and HVAC mounted, CE, RoHS and SGS certified. Four Hotel Collection fragrances at 100ml each in the box; no separate refill oil is sold today, so ask SOSA first.
Part one — the three variables that make the same machine right or wrong
Square footage is the variable everyone reaches for and it is the least discriminating of the four contexts, because a villa and a showroom can measure the same and want opposite things. What actually separates them is occupancy, authority and attention — who is in the building, who is allowed to touch the machine, and how many minutes a week anyone will spend maintaining the arrangement. Run these three before you compare prices, because they will usually settle the decision on their own.
1
VARIABLE ONE · OCCUPANCY
Who is in the room, and did they choose the scent?
In your own home, everyone breathing the fragrance chose it, tolerates it or can open a window and say so. In a business, a rental or a villa full of guests, most of the people in the room did not choose it and cannot adjust it. That changes the brief from "what do I like" to "what is unobjectionable at low intensity to a stranger", which is why the four Hotel Collection registers that ship with the machine sit where they do — white tea and bergamot, cedar and vetiver, amber and violet, citrus and sandalwood rather than anything loud or sweet. It also changes the intensity setting: a business runs lower than a home would, for longer, because the goal is a room that reads finished rather than a room that announces a fragrance. If everyone in your building chose the scent, you are in the weakest of the four contexts, and you probably want a machine you can lean over and turn down.
The rule: the more strangers in the room, the more the machine's restraint and its lock matter — and the less its raw output does.
2
VARIABLE TWO · AUTHORITY
Who is allowed to change the setting?
Sukoon₹1,899This is the variable nobody thinks about until they have lost control of a room. In a shop, someone on the evening shift decides it is too strong and turns it off; a week later it has been off for six days and the space has no identity. In a rental, a guest investigates the unfamiliar device on the console. The Vaayu's key-lock exists precisely for that, and it is the single feature that most justifies the price gap in a commercial setting — not because the machine is stronger, but because the setting you chose is the setting that persists. Scheduling does the same job in time rather than in access: 1h, 4h, 8h and 24h, with auto-stop, so the building's fragrance is a policy rather than a habit somebody has to remember. In your own home, none of that is worth much. You are the authority, and a remote-controlled Sukoon at ₹1,899 gives you all the governance you need.
The tell: if the honest answer to "who can change this?" is "anyone who walks past", you want a lock more than you want reach.
3
VARIABLE THREE · ATTENTION
How many minutes a week will this arrangement really get?
Reed diffusers want a weekly flip with gloves, six reeds per bottle, and an occasional refresh. Ultrasonic machines want tanks filled and rinsed. Both are trivial in a flat where you live and neither is trivial across a villa with six vessels or a property being turned over between guests. One 400ml tank at 90+ days a fill is roughly four fills a year — a number chosen once and then forgotten — where six reed bottles is fifty-two flipping sessions and a reorder every six to eight weeks. Attention is the variable that quietly converts a large-property owner from the reed answer to the machine answer, and it is a perfectly respectable reason to spend the money. It is also the reason a single household should be sceptical: if the arrangement is two bottles and a machine in one flat, the attention cost is already close to zero and there is nothing to buy your way out of.
Part two — the four contexts, ranked from strongest to weakest
The same machine, four buildings, four verdicts. Volume figures are typical rather than universal — measure your own connected volume in cubic metres before deciding, since ceiling height changes everything.
The context table
Four buildings, four answers
| Context | Typical connected volume | What it is really buying | Verdict | If not, buy this |
|---|---|---|---|---|
| 1. Business ★ | 200–800m³ open floor, no internal doors | Governance: one scent, scheduled, key-locked, staff-proof | Strongest case — Vaayu ₹11,999 | Above 1000m³: Aangan ₹25,999 or Meenar ₹38,500 |
| 2. Villa, open ground floor | 250–500m³ across hall, living, dining, stair void | Reach — one identity across a volume no bottle crosses | Strong, if it is genuinely one volume | Three Sukoons ₹1,899 × 3 = ₹5,697 |
| 2b. Villa, rooms with doors | Several 40–80m³ rooms, individually closed | Nothing a machine can deliver past the hinges | No — buy per room instead | Reeds ₹749–₹849 · 130ml ₹1,249–₹1,349 |
| 3. Airbnb, large, frequent turnover | 200–400m³ common floor, several changeovers a week | Turnover time — no bottles to touch at handover | Conditional yes, on labour grounds | Sukoon ₹1,899 in the common area plus reeds |
| 3b. Airbnb, one flat or studio | 60–120m³ total, one or two turnovers a week | Very little the cheaper machine does not do | No | Boond ₹899 or Sukoon ₹1,899 |
| 4. Single home, open plan | 90–180m³ living-dining-kitchen | Reach it can mostly get for a sixth of the price | Weak — usually no | Sukoon ₹1,899, or two at ₹3,798 |
| 4b. Single home, doors closed | One room at a time, 40–90m³ each | Nothing — this is not a coverage problem at all | Weakest case — no | Reeds from ₹749 · duo sets from ₹1,498 |
| The honest caveat: nothing in this table should be read as a claim about outcomes. Scenting a property does not raise a rating, a review score, a booking rate, an occupancy figure, a nightly rate or a sale — there is no evidence for any of that, and any seller who implies otherwise is inventing. What a scent machine does is put a chosen fragrance into a chosen volume at chosen times. Whether that is worth ₹11,999 depends on the size of the volume, on who controls the room and on how much attention the alternative arrangement would demand — the three variables above, and nothing else. | ||||

The SOSA principle
A home buys a preference. A business buys a standard.
Preferences can be adjusted by whoever is in the room, which is why a remote and a timer are enough. A standard has to survive the evening shift, the guest who fiddles, and the week you are not there — and that is what a lock and a schedule are for.
Part three — the weakest case, and why the strongest is strongest
The single-home enquiry is the one we receive most and the one I decline most, so it deserves the plainest treatment. A flat is not a large space; it is several small ones with doors between them. Even where the living, dining and kitchen are open to each other, the volume typically lands between 90 and 180 cubic metres, and the Sukoon at ₹1,899 covers 270–320 sq ft — roughly 75–90m³ at a standard 3m ceiling — so one machine covers most of it and two at ₹1,899 × 2 = ₹3,798 cover essentially all of it, placed at opposite ends where a single unit would have to cross the room. That is ₹11,999 − ₹3,798 = ₹8,201 kept, for an arrangement that is arguably better because it has two points of origin rather than one. The rooms you were most annoyed about are behind doors, and they need reeds regardless of what else you buy.
The business case is the strongest for reasons that have very little to do with strength. A commercial room is large, open, occupied by people who did not choose the fragrance, and staffed by people who should not be adjusting it — which is a precise description of what the Vaayu's feature list was built around. The 1h/4h/8h/24h timers mean the space is scented during trading hours and not at three in the morning; the key-lock means the intensity you set in March is still the intensity in September; the under-38 dB figure means it does not intrude on a conversation across a counter; and 5W with a 0.9 kg body that wall or HVAC mounts means it can be put somewhere out of reach and forgotten. Everything above 1000m³ is past this machine and into the Aangan at ₹25,999 for roughly 8,000–10,000 sq ft or the Meenar at ₹38,500 for 12,000–18,000 sq ft.
One caution that lands hardest on exactly the buyer with the strongest case. SOSA does not currently sell a separate Vaayu refill oil. The machine ships with four Hotel Collection cold-air fragrances at 100ml each — 400ml, specified at 90+ days per fill at a mid intensity setting — and that is the whole supply available from us today. A household running it a few hours a day will take a long time to reach the end of that; a business running eight hours a day, six days a week, will get there sooner, and a business is precisely the buyer for whom running out is a visible failure rather than a mild disappointment. The water-based Hotel Collection at 15ml ₹299, 100ml ₹999 and 300ml ₹1,799 is a different product for ultrasonic tanks and is not a substitute. Ask SOSA where refill supply stands before you commit; it is the right question in all four contexts and the urgent one in the commercial case.
In a home, you are the control system. In a business, the machine has to be — and that, not reach, is what the extra ten thousand rupees buys.

Part four — the setup I would actually specify for each
Complete arrangements rather than single products, because every one of these buildings has rooms behind doors that a machine will never reach. Totals are sums on our listed prices, not bundles.
Four specifications
What I would put in each building
| Building | The open volume | The closed rooms | The arithmetic | Total |
|---|---|---|---|---|
| Showroom or clinic ★ | One Vaayu, wall-mounted, key-locked, 8h timer | A 50ml reed in the washroom and the office | ₹11,999 + ₹749 + ₹799 | ₹13,547 |
| Villa, open ground floor | One Vaayu at the hall-to-living junction | 130ml reeds in four bedrooms | ₹11,999 + (₹1,299 × 4 = ₹5,196) | ₹17,195 |
| Villa, divided ground floor | Three Sukoons, one per room | 50ml reeds in bedrooms and baths | (₹1,899 × 3 = ₹5,697) + (₹749 × 4 = ₹2,996) | ₹8,693 |
| Large Airbnb, frequent turnover | One Vaayu on the common floor, scheduled to check-in | Reeds in the guest bedrooms, replaced quarterly | ₹11,999 + (₹1,249 × 3 = ₹3,747) | ₹15,746 |
| Single-listing flat or studio | One Sukoon, run for two hours before arrival | One reed in the bath | ₹1,899 + ₹749 | ₹2,648 |
| Ordinary home, open plan | Two Sukoons at opposite ends of the volume | A Day & Night duo in the bedrooms | (₹1,899 × 2 = ₹3,798) + ₹1,498 | ₹5,296 |
| Ordinary home, doors closed | Nothing — there is no open volume to scent | One reed diffuser per room, flipped weekly | ₹749 × 4 = ₹2,996 | ₹2,996 |
Honest notes for buyers: every total is arithmetic on SOSA's listed prices, shown as sums (₹11,999 + ₹749 + ₹799 = ₹13,547; ₹1,299 × 4 = ₹5,196; ₹1,899 × 3 = ₹5,697; ₹749 × 4 = ₹2,996; ₹1,899 × 2 = ₹3,798; ₹11,999 ÷ ₹1,899 ≈ 6.3; ₹11,999 − ₹3,798 = ₹8,201) rather than as bundles, offers or measured claims. Coverage, tank and runtime figures are manufacturer specifications and vary with connected volume, ceiling height, ventilation, intensity setting and season; measure your own volume in cubic metres before choosing. No claim is made or implied that scenting a property affects ratings, reviews, bookings, occupancy, nightly rate or revenue, and no health, wellness, mood, sleep, air-purification or odour-removal claim is made — ventilate first, scent second. SOSA does not currently sell a separate Vaayu refill oil; the 400ml in the box is today's whole supply, and buyers who need continuity — commercial buyers especially — should confirm the position with SOSA before purchasing. The cold-air oil is not the water-based Hotel Collection, despite shared scent names, and reed oil goes in no machine at all. The 6L Megh at ₹3,499 covers around 215 sq ft, less than the ₹1,899 Sukoon, and is a runtime and humidity machine, never a coverage upgrade. Warranty length, AMC, spare parts, installation service and bulk or corporate terms are not stated here — ask SOSA. Composed and handmade in small batches in Pune, and a portion of every order supports girl-child education through Nanhi Kali.
The part of every specification that never changes
SOSA Day & Night duo · 2 × 50ml ₹1,498
Whatever machine ends up on the open floor, the rooms behind doors want their own source, and that is true in a showroom washroom, a villa bedroom, a guest room and your own flat alike. Morning Freshness for a bathroom or a home office and Evening Calm for a bedroom, six fibre reeds each, 6–8 weeks at the calibrated count with a weekly flip. Fibre rather than rattan because rattan's pores clog in Indian humidity; alcohol-free and phthalate-free on a heat-stable CCT base tested through 45°C heat and 85% monsoon humidity. 2 × 130ml is ₹2,498 for 14–18 weeks a bottle, and the oil-only refills are ₹2,399 for 300ml and ₹3,499 for 500ml.

A note from Sonal
I noticed something after the first year of selling this machine: the enquiries divide almost perfectly into two groups, and they ask different questions. The commercial buyers ask about scheduling, locking, mounting and supply. The domestic buyers ask whether it is stronger. That difference is the whole of this page — the commercial buyer has already worked out that they are buying control, and the domestic buyer is usually still hoping to buy power.
Power is the thing least worth paying for here. If a room in your flat smells of nothing, the cause is almost always a closed door, a bottle in dead air, a balcony left open, or a machine nobody switched on — and none of those is corrected by a bigger machine. Control, on the other hand, is genuinely hard to get any other way, and if you are responsible for a space that other people walk into, it is worth real money.
On the Airbnb question I want to be unusually blunt, because the marketing in that corner of the internet is not. Nobody can tell you that scenting a property will move your rating, your reviews or your bookings. I have seen no evidence for it and I will not repeat the claim to sell a machine. What I will say is that a guest forms an impression in the first ninety seconds after a door opens, that the impression is real, and that it is worth caring about for its own sake. Buy on that basis or do not buy. Everything we make is composed and handmade in small batches in Pune, and a part of every order funds a girl's classroom through Nanhi Kali.
Frequently asked questions
Is a SOSA Vaayu worth it for a normal home?
Usually not. A flat's connected volume is typically 90–180m³ against a machine rated up to 1000m³, and the rooms that disappoint you are generally behind closed doors, which no machine crosses. A Sukoon at ₹1,899 covers 270–320 sq ft with a remote and timers, and two at ₹1,899 × 2 = ₹3,798 cover an open living-dining better than one unit crossing it. Reeds from ₹749 handle the closed rooms.
Is it worth it for a villa?
Yes, if the common floor is genuinely one connected volume of roughly 250 cubic metres or more — a hall running into living and dining with a stair void, no doors between them. If instead it is three separate rooms with doors, three Sukoons at ₹1,899 × 3 = ₹5,697 is cheaper and gives you three independent schedules. Bedrooms need their own reeds either way.
Will scenting my Airbnb improve my ratings or bookings?
Nobody can promise that, and I would not believe anyone who does — there is no data connecting scenting to ratings, review scores, bookings, occupancy or nightly rate. What is real is the guest's experience in the first ninety seconds after the door opens, which is describable and worth caring about on its own terms. Judge the purchase on volume, control and the labour it saves at turnover, not on an outcome claim.
Why is the business case the strongest?
Because a commercial space combines the two things the machine is actually good at: a large open volume with no internal doors, and a need for the setting to persist without staff adjusting it. The 1h/4h/8h/24h timers, the auto-stop and the key-lock are what you are paying for; under 38 dB and a 0.9 kg wall or HVAC mountable body are what let it sit somewhere out of reach. Above 1000m³ you are past it — Aangan ₹25,999, Meenar ₹38,500.
Can I buy more fragrance for it later?
SOSA does not currently sell a separate Vaayu refill oil. The machine ships with 400ml — four Hotel Collection cold-air fragrances at 100ml each — specified at 90+ days per fill at a mid intensity setting, and that is today's whole supply. The water-based Hotel Collection at 15ml ₹299, 100ml ₹999 and 300ml ₹1,799 is for ultrasonic machines and is not a substitute. Confirm current availability with SOSA before purchasing, particularly for a commercial installation.

Editorial standards & sources
About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body, comparing the case for a cold-air scent machine across four contexts — a private home, a villa, a short-let property and a commercial space. Machine specifications are manufacturer figures from the live product pages. Every price total is arithmetic on SOSA's listed prices, shown as sums (₹11,999 + ₹749 + ₹799 = ₹13,547; ₹1,299 × 4 = ₹5,196; ₹1,899 × 3 = ₹5,697; ₹1,899 × 2 = ₹3,798; ₹749 × 4 = ₹2,996; ₹11,999 ÷ ₹1,899 ≈ 6.3), not bundles or offers. Volume figures are typical illustrations, not measurements of any particular property, and behaviour varies with ceiling height, ventilation, furnishing, intensity setting and season. No claim is made or implied that scenting affects ratings, reviews, bookings, occupancy, nightly rate or revenue, and no health, wellness, mood, air-purification or odour-removal claim is made. Warranty length, AMC, spare parts, installation service and bulk or corporate terms are not stated because they are not figures SOSA publishes — ask SOSA directly.SOSA Vaayu specifications (verified from the live product page, August 2026): ₹11,999 (the product page displays a rounded ₹12,000). Waterless cold-air nebulisation — pressurised air atomises undiluted fragrance oil into a dry nano-mist; no water, no heat, residue-free. Coverage up to 1000m³, about 2,000–3,000 sq ft. 400ml refillable tank, 90+ days per fill at a mid intensity setting. Bluetooth app plus onboard buttons, 1h / 4h / 8h / 24h timers, adjustable mist intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. 165 × 80.5 × 215 mm, 0.9 kg, black or white. Freestanding or wall / HVAC mount. CE, RoHS and SGS certified. Ships with four SOSA Hotel Collection fragrances at 100ml each (400ml in total) in one of three combos chosen at checkout. SOSA does not currently sell a separate Vaayu refill oil; the 400ml supplied in the box is the fragrance available at the time of writing, and buyers who need long-term supply should confirm current refill availability with SOSA before purchasing. The cold-air oil supplied with the Vaayu is a different product from the water-based Hotel Collection sold for ultrasonic machines (15ml ₹299 · 100ml ₹999 · 300ml ₹1,799), which must not be used in a Vaayu despite sharing scent names. Other SOSA machines: Boond 300ml ₹899 (~150 sq ft) · Sukoon 500ml ₹1,899 (270–320 sq ft) · Megh 6L ₹3,499 (~215 sq ft — a runtime and humidity machine, not a coverage upgrade) · Aangan ₹25,999 (~8,000–10,000 sq ft) · Meenar ₹38,500 (12,000–18,000 sq ft) · Safar car diffuser ₹3,999.

Runtime, consumption and coverage figures are manufacturer specifications and vary with intensity setting, run hours, ceiling height, ventilation and season; any per-month or per-day figure in this guide is arithmetic on those specifications, not a measurement. Electricity costs vary by state tariff. No claim is made that scenting affects ratings, reviews, bookings, occupancy, revenue, health, mood or air quality. Free shipping above ₹499.
