You do not need one if the doors stay shut. A closed door is a wall, and no coverage rating crosses it. Reed diffusers from ₹749 per room are the honest answer.
You do not need one for runtime, humidity, night-light, or a car. Those are the Megh ₹3,499, the Boond ₹899 and the Safar ₹3,999 respectively.
And nobody should buy one for guaranteed long-term supply. SOSA does not currently sell a separate Vaayu refill oil — the 400ml in the box is today's whole supply, so confirm availability with SOSA before you commit.
2. Anyone whose internal doors close. A shut door is a wall to fragrance. A four-bedroom flat with the bedrooms closed is not one large space; it is five small ones, and five small spaces want five small sources — reed diffusers from ₹749 each.
3. Anyone scenting a bedroom, nursery or reading corner. These rooms want the quietest thing you can put in them, not the strongest. Evening Calm at ₹799 for 50ml, no plug, no hum, no tank.
4. Anyone scenting a bathroom, entrance or desk. A Boond at ₹899 covers about 150 sq ft on USB, or a 50ml reed at ₹749 does it with no electricity at all.
5. Anyone who wants runtime or winter humidity rather than reach. That is the Megh at ₹3,499 — 6L, about 100 hours a fill. Note carefully that it covers only around 215 sq ft, less than the ₹1,899 Sukoon. Buy it for runtime and moisture, never for coverage.
6. Anyone who wants to change scent often. The Vaayu holds 400ml of one oil for 90+ days. If you like a different fragrance every fortnight, a Sukoon at ₹1,899 plus Hotel Collection 15ml bottles at ₹299 is the flexible setup.
7. Anyone whose home is empty for long stretches, or who has no socket where the scent is needed. Reeds work unattended for 6–8 weeks (50ml) or 14–18 weeks (130ml) with no power at all.
8. Anyone who needs guaranteed multi-year fragrance supply. SOSA does not currently sell a separate Vaayu refill oil. The 400ml in the box is the whole supply available today. If uninterrupted supply matters to you, confirm current availability with SOSA before purchasing, or stay on the reed line where refills exist at ₹2,399 for 300ml and ₹3,499 for 500ml.

Part one — three tests, and failing any one of them rules the machine out
Before the eight profiles, three questions that settle most cases in about five minutes. They are deliberately blunt, and I would rather you ran them than read a specification sheet, because a specification sheet describes what a machine can do rather than what your building will let it do. The Vaayu's coverage figure is a volume figure — up to 1000m³ — and a volume figure only means something once you know how much of your home is actually one volume. That is the first test. The second is whether the space is separated by doors. The third is whether the thing you want is reach at all, or something else that reach has been standing in for.
Evening Calm₹799 · 50mlThis is the test that saves the most money and the one almost nobody runs. Walk through the property as you actually live in it and count the internal doors that are shut for most of the day — bedrooms, the study, the guest room, bathrooms. Every one of them is a wall, and no coverage rating in this industry crosses a wall. A four-bedroom home where the bedroom doors close is not one large scenting problem; it is one medium problem in the common area and four small ones behind doors. The medium one is a Sukoon at ₹1,899 or a well-placed reed diffuser; the four small ones are 50ml reeds at ₹749–₹849 each. Buying a 1000m³ machine to solve that is buying reach that stops at the first door hinge, and the rooms you were most annoyed about will still smell of nothing.Part two — the eight buyers who should keep their money
Each row is a person who writes to us. The middle column is what they are actually trying to fix, and the right-hand columns are what I would send them instead, priced from our own listings. Coverage and runtime figures are manufacturer specifications and vary with ceiling height, ventilation, intensity setting and season.
| The buyer | What they are really solving | Why the Vaayu is wrong for them | Buy this instead | Price |
|---|---|---|---|---|
| 1. One living room ★ | A 200–320 sq ft sitting or living-dining room that reads flat | Roughly 100–150m³ against a 1000m³ rating — you cannot use the reach | Sukoon, remote and timers, three scents in the box | ₹1,899 |
| 2. The closed-door flat | Four or five rooms, each wanted, doors shut most of the day | Coverage does not cross a shut door; four rooms stay unscented | A 50ml reed per room, or a Day & Night duo | ₹749–₹849 each · duo ₹1,498 |
| 3. The bedroom buyer | A room that should be quiet, dark and unmechanical at night | A powered machine with an app is the opposite of what this room wants | Evening Calm 50ml, six fibre reeds, no plug | ₹799 · 130ml ₹1,299 |
| 4. The bathroom or entrance | A small space, often under 100 sq ft, wanted fresh not fragrant | Rated for up to 1000m³ — a bathroom is under one per cent of that | Boond ~150 sq ft, or Morning Freshness 50ml | ₹899 · or ₹749 |
| 5. The runtime buyer | Wants days of unattended running, and moisture in a dry winter | The Vaayu is dry by design and adds no humidity whatsoever | Megh 6L, ~100 hrs a fill — ~215 sq ft, less than the Sukoon | ₹3,499 |
| 6. The scent-switcher | Wants a different fragrance every week or two | 400ml of one oil is a 90+ day commitment to a single scent | Sukoon plus 15ml Hotel Collection bottles | ₹1,899 + ₹299 each |
| 7. The absent owner | A second home or flat empty for weeks; wants it right on arrival | A scheduled machine still needs power and a tank; nothing runs a scent for a month unattended better than a bottle | 130ml reeds, 14–18 weeks, no electricity | ₹1,249–₹1,349 |
| 8. The supply-certainty buyer | Wants to know the fragrance will still be purchasable in year two | No separate Vaayu refill oil is sold today — 400ml in the box is the whole supply | The reed line, where oil-only refills exist and are priced | ₹2,399 / 300ml · ₹3,499 / 500ml |
| The honest caveat: none of these eight rows says the Vaayu is a bad machine. It is a properly specified cold-air nebuliser — up to 1000m³, 400ml tank, 90+ days a fill, 1h/4h/8h/24h timers, key-lock, under 38 dB, 5W, CE, RoHS and SGS certified — and for a villa ground floor, a whole-floor serviced property or a commercial room it is the right tool and the cheapest way to get that reach in our range. The rows exist because price reads as capability, and the single most expensive habit in this category is buying up the ladder when the problem is on a lower rung. If you are genuinely at several hundred cubic metres of connected volume, see who should buy it instead. | ||||
Part three — the ninth reason, which applies to everybody
There is one more reason to hold off, and unlike the eight above it is not about the size of your home. SOSA does not currently sell a separate refill oil for the Vaayu. The machine ships with four Hotel Collection fragrances at 100ml each — 400ml in total, which the specification puts at 90+ days per fill at a mid intensity setting — and that quantity is the whole cold-air fragrance supply available from us today. I would rather write that sentence on our own page than have you discover it in month four. If long-term supply matters to you, and for most buyers of a ₹11,999 machine it will, ask SOSA directly about current refill availability before you place the order rather than after.
The point that is easy to miss, and that I want to state precisely because our own product page has been loose about it: the oil in the Vaayu box is a different product from the water-based Hotel Collection we sell for ultrasonic machines at 15ml ₹299, 100ml ₹999 and 300ml ₹1,799. They share scent names, which is where the confusion comes from, but the cold-air machine nebulises undiluted oil and the ultrasonic line is water-based for a tank. The ₹999 bottle is not a Vaayu refill and must not be used as one. If you are reading a comparison anywhere — ours or anyone else's — that quietly prices a Vaayu's running cost using those figures, the arithmetic is wrong.
Compare that with the reed line, where the supply question has a boring, complete answer: oil-only refills at ₹2,399 for 300ml and ₹3,499 for 500ml, which is ₹2,399 ÷ 300 ≈ ₹8 per millilitre and ₹3,499 ÷ 500 ≈ ₹7 against ₹749 ÷ 50 ≈ ₹15 for a fresh 50ml bottle. Those are sums on our own listed prices, not measurements. A cheaper product with a settled supply chain is a better purchase than an expensive one with an open question, and that is true regardless of how large your house is. It is also, I think, the single most useful line in this cluster, which is why it appears here rather than buried in a footnote.
Part four — what ₹11,999 buys instead
If you have decided against the machine, here is what the same money does elsewhere in the range, arranged from smallest problem to largest. Every figure below is arithmetic on our listed prices, and the totals are sums rather than offers.
| The setup | What it covers | The arithmetic | Total | Kept from ₹11,999 |
|---|---|---|---|---|
| One Sukoon ★ | One living room or open living-dining, on a timer | ₹1,899, three 15ml fragrances included | ₹1,899 | ₹10,100 |
| A 2BHK, fully scented | Living-dining on demand, plus two bedrooms and a bath | ₹1,899 + ₹749 + ₹799 + ₹799 = ₹4,246 | ₹4,246 | ₹7,753 |
| A 3BHK, reeds throughout | Five rooms behind doors, unattended for 6–8 weeks | ₹749 × 3 = ₹2,247, plus a Warmth & Bloom duo ₹1,598 | ₹3,845 | ₹8,154 |
| Two machines, two floors | Two separate common areas of up to 270–320 sq ft each | ₹1,899 × 2 = ₹3,798 | ₹3,798 | ₹8,201 |
| Runtime and winter humidity | ~100 hrs a fill — but only ~215 sq ft, less than the Sukoon | Megh ₹3,499 — bought for runtime, never for reach | ₹3,499 | ₹8,500 |
| Three years of reed oil | One or two vessels kept running continuously | ₹3,499 for 500ml ≈ 14–18 months, so two of them ≈ 28–36 months | ₹6,998 | ₹5,001 |
| Not an alternative: a bigger reed bottle | No change in reach at six reeds — 14–18 weeks instead of 6–8 | ₹1,249–₹1,349 buys duration, not coverage | ₹1,349 | Stated so you do not buy it for the wrong reason |
Versailles
We sell the Vaayu, so a page arguing that most people should not buy it needs an explanation. Here is mine. In the years since we started, the emails that have cost me the most sleep are not the ones about a fragrance somebody disliked — taste is taste, and we take those returns cheerfully. They are the ones that begin "I spent a lot of money and the problem is still there." That email is almost always the result of a buyer matching a large price to a large frustration rather than matching a machine to a measurement.
The frustration is real. A villa or an open-plan flat that will not hold a scent is genuinely annoying, and a ₹11,999 machine looks like it should be the end of the annoyance. Often it is not, because the annoyance was a shut door, a balcony left open until eleven, a bottle standing in dead air behind a sofa, or a room that simply needed a ₹1,899 machine and a timer. None of those are fixed by more money. Some of them are fixed in an afternoon by moving something.
So the eight profiles on this page are the eight versions of that email, written out in advance. If you recognise yourself in one, please buy the cheaper thing — and if the cheaper thing does not solve it, write to us and we will tell you honestly whether the machine would. 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. I would rather have that portion arrive from a ₹749 bottle you were pleased with than from a ₹11,999 machine you were not.

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.

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.
