Mountain Breeze ₹849
Sukoon ₹1,899
Hotel Collection 300ml ₹1,799
Vaayu ₹11,999
Morning Freshness ₹749
The Vaayu refill gap, stated plainly. The Vaayu ₹11,999 ships with 400ml of cold-air oil, roughly 90+ days at a mid setting, and no separate refill of that oil is sold at the time of writing. A practice planning continuous or multi-site use must confirm current availability with SOSA before committing. The water-based Hotel Collection is not a substitute and must not be used in a Vaayu.
The most reliable signature for most practices is a reed one. Mountain Breeze 130ml ₹1,349 lasts 14–18 weeks, so roughly three bottles a year — 3 × ₹1,349 = ₹4,047 — and the consumable is an ordinary catalogue item.
What this page will not claim: a signature does not calm anyone, shorten a wait, aid recovery, or affect reviews, footfall, retention or revenue. Nothing here is medical, clinical or safety advice.
2. Supply is the gate, and it comes before the composition. Decide what you can re-buy, then choose within that. Reed oil and the water-based Hotel Collection are ordinary catalogue items. The Vaayu's cold-air oil is not: no separate refill is sold at the time of writing, and the 400ml in the box — roughly 90+ days at a mid setting — is the whole supply available. For a home that is an inconvenience. For a practice standardising an identity on one scent, it is a business problem, and I would not build a signature on it without a written answer from us first.
3. An interruption costs more than never starting. A neutral reception is unremarkable. A reception that smelled of one thing for eighteen months and now smells of another is a change people register, and the only thing it communicates is that something behind the scenes did not hold.
4. A signature raises your obligations, it does not lower them. Running one composition constantly for years means the fragrance-free seat matters more, not less; that the level must be locked so it does not creep up over months; and that staff who sit in it for eight hours a day should be asked about it more than once. Key-lock and scheduled run windows exist for exactly this.
5. It still lives in one zone only. Examination rooms, refraction and diagnostics, consultation cabins, dilation bays, the procedure suite and post-operative areas get nothing, signature or not. Freestanding in reception, set back from the corridor, and never mounted into shared air-conditioning in a clinical building.
6. Nothing here is clinical advice, and no business claim is made. Ventilation, infection control and patient suitability rest with you and your clinicians.

Part one — what a signature actually commits you to
Practices usually arrive at this having seen it work elsewhere — a hotel group, a retail chain, an airline lounge. Those organisations have procurement departments, contracts and an account manager. What they are buying is not a fragrance but a guarantee of sameness, and that guarantee is the part a small practice has to construct for itself. Three things follow.
Vaayu waterless₹11,999 · confirm refill firstHere is the position as it stands, stated as plainly as I can. Reed compositions and the water-based Hotel Collection for ultrasonic machines are ordinary catalogue products you can reorder yourself. The Vaayu is different: it ships with 400ml of cold-air oil lasting roughly ninety days or more at a mid setting, and no separate Vaayu refill oil is sold at the time of writing. The Hotel Collection is water-based, made for ultrasonic machines, and must not be used in a Vaayu despite sharing scent names — so it is not a workaround. If a Vaayu is genuinely the right machine for your arrival zone, buy it for what it does; but a practice planning continuous running, and certainly one planning several branches, should get a current answer through the contact page before making one scent the identity of the business. Those Hotel Collection scents are inspired by the atmosphere of well-known hotels; SOSA is an independent Indian brand, unaffiliated with any hotel group.Part two — the requirements, and where SOSA stands
Seven things a signature needs, and an honest column on what is actually available today. Two of the rows are the reason this page exists.
| Requirement | Why a practice needs it | Where SOSA stands today | Verdict |
|---|---|---|---|
| A repeatable consumable ★ | The scent must be identical in two years or the signature is not one | Reed oil and water-based Hotel Collection are catalogue items; Vaayu cold-air oil has no separate refill listed | Green for reeds and ultrasonic; open question for Vaayu — ask first |
| Continuous availability of one composition | A discontinued scent ends a signature at no notice | No discontinuation policy or product-life commitment is published | Keep a reserve; do not assume permanence for any single item |
| Consistency across several branches | Two branches with different scents is worse than none with any | No multi-location programme is published | Single site first; discuss multi-site through the contact page |
| Bulk or commercial purchasing terms | Predictable cost and invoicing for a recurring operational spend | No bulk pricing, corporate account, slab or stated invoicing arrangement is published | Assume retail pricing; ask rather than assume |
| A locked, non-drifting level | Settings creep upward over months when anyone can change them | Key-lock, adjustable intensity and 1h / 4h / 8h / 24h run windows on the Vaayu; steady / 2H / 4H timers on the Sukoon | Genuinely available — this is a real operational feature |
| A way to switch it off immediately | Somebody will ask, and the answer cannot be "we can't" | Any machine switches off; a reed diffuser has no off switch and must be removed from the room | Machine formats are better here than reeds |
| Servicing, spares and warranty for the hardware | A signature that depends on one machine depends on that machine being repairable | Warranty term, spare parts, servicing and app platform are unconfirmed | Ask before committing; do not infer a term that is not stated |
| The honest caveat: this table describes commercial and product availability at the time of writing, not clinical guidance, and nothing in it claims any effect on any person or on the performance of a practice. Availability changes — confirm anything load-bearing with SOSA through the contact page before you commit, and treat an unanswered supply question as a reason to wait rather than a detail to settle later. | |||

Part three — when a clinic should not do this at all
The first case is a practice that enjoys changing things. A different scent in winter is a legitimate preference — but it is not a signature, and calling it one only sets up the disappointment. Run what you like at a low level and stop worrying about consistency. The second is a practice with three or more branches that wants them all identical. There is no published multi-location programme, no bulk pricing and no stated lead time, so prove it in one branch and ask us in writing before rolling it anywhere.
The third is any practice where the reception cannot be separated from the clinical route by real distance, or where the front of the building is small and poorly ventilated — a closed room gets heavier with a fragrance, not fresher. A children's eye clinic or a large paediatric caseload is the one I decline outright, and a practice whose real complaint is a cleaning or disinfectant smell should fix that first, since fragrance covers nothing and layering it produces a third smell worse than either.
The fourth is the one I have already made and will make again, because it is the most expensive mistake available here. Do not build a signature on a machine whose consumable you cannot currently re-buy. The Vaayu is an excellent piece of equipment for a large arrival zone — under 38 dB, key-lock, scheduled run windows, no water and no plume — and none of that changes the fact that no separate cold-air refill oil is listed at the time of writing. Buy it for a reception that needs it. But if the plan is one scent, every branch, for five years, get a written answer on refill supply from the contact page before spending anything.
Part four — should you start one? by practice profile
Find the row that matches your practice. Three of the six say wait or no, and those are the rows I would most like to be read.
| Practice profile | Start a signature? | The format that can hold it | Confirm first |
|---|---|---|---|
| Single clinic, arrival zone under ~150 sq ft ★ | Yes — this is the easiest case in the cluster | Mountain Breeze 130ml, about three bottles a year: 3 × ₹1,349 = ₹4,047 | Nothing beyond ordinary stock — reeds are not sold separately, so keep a spare bottle |
| Single clinic, 150–320 sq ft reception and waiting | Yes, with a machine so the level can be locked and scheduled | Sukoon ₹1,899 plus one Hotel Collection 300ml ₹1,799 held as the standard | That the specific scent you choose remains listed; keep one spare bottle |
| Single site, 320+ sq ft of connected public area | Only after the supply answer | Vaayu ₹11,999, freestanding, lowest intensity, run window on opening hours, key-lock on | Current Vaayu cold-air refill availability, in writing, before committing |
| Two or more branches wanting one identity | Not yet — prove it in one branch | Whatever the smallest branch can hold; consistency beats ambition | Multi-site supply, terms and lead time — none of which is published |
| A practice that likes to vary the scent | No, and no harm done | Any low, dry composition in the arrival zone, changed when you please | Nothing — you do not want a signature, you want a nice reception |
| Paediatric caseload, or a small under-ventilated reception | No | None. Ventilation first, and in a children's clinic I would not scent at all | ₹0 — this is the row I would rather you land on than the wrong yes |
Versailles
The first practice that asked me about a signature had four branches and a brand consultant, and what they wanted was a paragraph they could put in a document. What I gave them instead was a question: can you buy this exact oil, in this quantity, in eighteen months? Nobody in the room had asked it, and it turned out to be the only question that mattered.
I would rather say this on my own page than have a practice find it out later. SOSA does not currently sell a separate cold-air refill oil for the Vaayu. The 400ml in the box is the supply available at the time of writing, and while that is fine for a home it is not a foundation for a business identity. If you want a signature today and you want it to hold, the reed range and the water-based Hotel Collection are the honest formats, because you can reorder both yourself without asking anyone's permission.
There is a version of this page that would have sold more machines and put the refill position in a footnote. It would have been worth nothing to a practice owner, who is professionally cautious for good reasons and can spot a hedge from a long way off. Made in Pune in small batches, and a part of every order funds a girl's classroom through Nanhi Kali.

CE, RoHS and SGS certified. SOSA does not currently sell a separate Vaayu cold-air refill oil; the 400ml supplied in the box is the fragrance available at the time of writing, so a practice planning continuous or multi-site use should confirm current refill availability with SOSA before committing. The water-based Hotel Collection is made for ultrasonic machines and must not be used in a Vaayu. Other machines: Boond 300ml ₹899 (~150 sq ft, ultrasonic) · Sukoon 500ml ₹1,899 (270–320 sq ft, 16–18 hours on low, remote and steady/2H/4H timers, three 15ml fragrances included, ultrasonic) · Megh 6L ₹3,499 (~215 sq ft — a runtime and humidity machine that covers less than a Sukoon, never a coverage upgrade) · Safar ₹3,999 (waterless cold diffusion, cordless, 20ml, about 6.9cm, three speeds, 1/2/3-hour auto-off — sold as a car and travel diffuser, personal-scale only; SOSA publishes no coverage figure for it) · Aangan ₹25,999 (HVAC nebulising, ~8,000–10,000 sq ft) · Meenar ₹38,500 (commercial HVAC, 12,000–18,000 sq ft). Water-based Hotel Collection for ultrasonic machines: 15ml ₹299 · 100ml ₹999 · 300ml ₹1,799 · pack of seven ₹1,799; scents are inspired by the atmosphere of well-known hotels — SOSA is an independent Indian brand and is not affiliated with, endorsed by or supplying any hotel group. Reed diffusers ₹749–₹1,349 (50ml 6–8 weeks, 130ml 14–18 weeks, six fibre reeds, no 100ml size; replacement reeds are not sold separately). Reed oil cannot be used in an ultrasonic machine and Hotel Collection oil cannot be used in reeds. SOSA sells no room spray or home spray — every SOSA spray is a car perfume. Nothing in this guide is medical, clinical or safety advice. A fragrance diffuser adds a scent to the air. It does not clean, purify, filter, sanitise or disinfect air, does not remove or neutralise disinfectant, damp or occupancy smells, and has no effect on comfort, anxiety, waiting time, recovery or any clinical outcome. Some people are sensitive to airborne fragrance, which is why this guide recommends that examination rooms, diagnostic areas, consultation cabins, procedure suites and post-operative areas remain fragrance-free, that a fragrance-free seating option always exist, and that a diffuser is never mounted into shared HVAC in a clinical building. Decisions about clinical policy, ventilation standards, infection control and patient suitability rest entirely with the practice and its clinicians. A persistent stale, damp or disinfectant smell is a ventilation, moisture or cleaning problem — SOSA sells no dehumidifier and no air purifier, and fragrance should never be used to cover one. Coverage, runtime and longevity figures are manufacturer specifications and typical ranges, not guarantees, and vary with room volume, ceiling height, air exchange, occupancy and season. SOSA publishes no commercial or bulk pricing, no corporate account, no annual maintenance contract, no installation service, no stated warranty term and no multi-location programme; warranty length, spare parts, servicing and app platform availability are unconfirmed, and larger or multi-site enquiries should go through the contact page before any commitment.
