Founder Diaries · Clinical Boundary · Reception vs Examination
Examination room: no, and no version of the question turns into a yes. Not a discreet bottle, not a machine on a schedule, not a weaker composition, not "only between patients". The clinical pathway stays fragrance-free.
What decides it is not the smell — it is choice and duration. A person in your waiting area chose to sit there, can move seats, and leaves when called. A person at the slit lamp is positioned, still, close, and cannot step outside for a minute.
Then size to the arrival zone, never to the clinic. Under ~150 sq ft of reception, a reed diffuser from ₹749. From 150 to 320 sq ft, a Sukoon ₹1,899. Past that, a freestanding Vaayu ₹11,999 — never ducted into shared air-conditioning.
Mountain Breeze₹849 · arrival zone onlyPractices debate this as though the patient were the only person in the room, and the patient is in it for the shortest time. A consulting ophthalmologist or an optometrist occupies one cabin for eight or nine hours; the patient occupies it for eight or nine minutes. Anything constant in that room is a decision about your colleague's whole working day, taken on the strength of a few minutes of somebody else's. The same asymmetry exists in reception, which is why the level there is set for the person at the desk rather than the visitor passing through — but there the exposure sits in a large, ventilated, shared volume and the person at the desk is a party to the decision. In a cabin the volume is small, the door is closed, and the exposure is concentrated. Ask the people who work in a room before you change its air, and treat one objection as a no.

SOSA range, specifications and prices used in this guide (verified August 2026): Vaayu ₹11,999 — waterless cold-air nebulisation of undiluted fragrance oil; no water, no heat, no added humidity, no white mineral dust. Coverage up to 1000 m³, about 2,000–3,000 sq ft. 400ml refillable tank lasting roughly 90+ days at a mid setting. Bluetooth app plus onboard controls, 1h / 4h / 8h / 24h run windows, day selection, adjustable intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. Freestanding or wall / HVAC mount. 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.

These two rooms are often forty feet apart and they belong to different buildings. Reception and the waiting seats are hospitality space, and they are the only part of an eye practice where this conversation belongs. The examination room is clinical space, and nothing SOSA sells goes in it — not a bottle, not a machine, not a lower setting, not on a timer, not overnight. That is not a hedge I soften later. What follows is a straight comparison of the two rooms on the ten variables that actually differ between them: why the person is there, whether they chose to be, how long they stay, how long your own staff stay, and who owns the choice. Not one of those ten has the same answer in both rooms.
Quick answers — read this first
Reception: yes, at the lowest level that registers. One source, behind the desk line at the far end of the zone from the corridor mouth, set for the person who sits there eight hours rather than the visitor passing through.Examination room: no, and no version of the question turns into a yes. Not a discreet bottle, not a machine on a schedule, not a weaker composition, not "only between patients". The clinical pathway stays fragrance-free.
What decides it is not the smell — it is choice and duration. A person in your waiting area chose to sit there, can move seats, and leaves when called. A person at the slit lamp is positioned, still, close, and cannot step outside for a minute.
Then size to the arrival zone, never to the clinic. Under ~150 sq ft of reception, a reed diffuser from ₹749. From 150 to 320 sq ft, a Sukoon ₹1,899. Past that, a freestanding Vaayu ₹11,999 — never ducted into shared air-conditioning.
The short answer
Short answer: use it in reception and waiting, and nowhere past the consultation door. The examination room, the refraction lane, the diagnostic stations, the consultation cabin, the procedure suite and every post-operative area get nothing at any level or any hour.
The mechanism, in one line: in reception a person is present by their own arrangement, for a stretch they can interrupt, in a seat they can change. In an examination room they are positioned at an instrument and held still at close range — and your optometrist is in that same air all day rather than for nine minutes.

Straight answer
Reception or examination room — where should an eye clinic use fragrance?
1. Reception, and only reception. The waiting seats, the desk, the entrance that shares their air, and the billing counter if it sits in the same volume. One source, at the lowest level that registers as pleasant rather than as a fragrance.
2. The examination room takes nothing, and the answer does not soften with a smaller product. A 50ml bottle is not a compromise version of a machine; it is the same decision at a lower volume.
3. The reason is choice. A person in your waiting area chose the seat, can move to another, and can step outside without consequence. A person at a slit lamp has been positioned and asked to hold still. Ambience is only ever offered to someone who can decline it.
4. The second reason is your own staff. An optometrist works in one cabin for eight or nine hours; a patient is in it for eight or nine minutes. The constant belongs to your colleague, not to the visitor.
5. The third is that a clinical room is where competence is demonstrated, and ambience must never compete with that signal. The target for an eye practice is considered, not scented.
6. Some people are sensitive to airborne fragrance. That is why the clinical pathway stays clear and why a fragrance-free seat should exist in the waiting area — not a claim that anything is harmful, and not a claim that anything is safe. Both belong to the practice and its clinicians.
7. Check the boundary is real before buying. If cabin doors stand open onto the waiting area, you have one room with a partition rather than two — fix the door first.
8. Then size to the arrival zone, never to the clinic. Under about 150 sq ft, a reed diffuser from ₹749. From 150 to 320 sq ft, a Sukoon at ₹1,899. Past roughly 320 sq ft of open reception, a freestanding Vaayu at ₹11,999 — never mounted into shared HVAC. Made in small batches in Pune, and a portion of every order supports girl-child education through Nanhi Kali.

Made in small batches in Pune, and a portion of every order supports girl-child education through Nanhi Kali.
TL;DR: reception yes, examination room no, and no setting or format changes that. The split rests on choice, duration and staff exposure. Size to the arrival zone: reeds from ₹749, Sukoon ₹1,899, Vaayu ₹11,999.
The product for the room that is in scope
SOSA Sukoon · 500ml ultrasonic, 270–320 sq ft ₹1,899
Once the out-of-scope rooms are subtracted, most Indian eye clinic receptions land between 150 and 320 sq ft — exactly the span this machine is specified for. 500ml, sixteen to eighteen hours on low, a remote, and steady / 2H / 4H timers. Three 15ml Hotel Collection fragrances come in the box — water-based, for ultrasonic machines only, and inspired by the atmosphere of well-known hotels; SOSA is an independent Indian brand, unaffiliated with any hotel group. It belongs behind the desk line at the far end of the waiting zone from the corridor, and nowhere else in the building. It is ultrasonic, so it adds a little humidity — one more reason it stays away from paper records and instruments even inside the zone.
Part one — the three differences that carry the argument
Ten variables separate these two rooms and the full list is in Part two, but three of them do almost all the work. If you remember three sentences from this page, make them these — each can be checked against your own building in an afternoon rather than argued about.
1
DIFFERENCE ONE · WHETHER THE PERSON CAN DECLINE
Ambience is only ever offered to someone who can get up and move
A waiting room is a place people occupy on their own terms. They pick a chair, they change chairs, they step out to take a call, they stand by the door if the room is warm. Every one of those small freedoms is what makes an ambient decision defensible: the person retains the ability to opt out of it without cost. An examination room removes all of them at once. The patient is seated at an instrument, positioned by a technician, asked to hold a chin in a rest and not to move. Nothing about that is unreasonable — it is the job. But it means a constant in that air is imposed rather than offered, on the one person in your building with the least room to say so. In reception you can do something structural about it: keep a defined seat the fragrance does not reach, so declining is a chair rather than a conversation. There is no equivalent move at a slit lamp.
The one-line rule: if the person cannot move seats, the room is not a candidate.
2
DIFFERENCE TWO · WHO IS ACTUALLY EXPOSED
A patient is in the cabin for minutes; your optometrist is in it all day
Mountain Breeze₹849 · arrival zone onlyPractices debate this as though the patient were the only person in the room, and the patient is in it for the shortest time. A consulting ophthalmologist or an optometrist occupies one cabin for eight or nine hours; the patient occupies it for eight or nine minutes. Anything constant in that room is a decision about your colleague's whole working day, taken on the strength of a few minutes of somebody else's. The same asymmetry exists in reception, which is why the level there is set for the person at the desk rather than the visitor passing through — but there the exposure sits in a large, ventilated, shared volume and the person at the desk is a party to the decision. In a cabin the volume is small, the door is closed, and the exposure is concentrated. Ask the people who work in a room before you change its air, and treat one objection as a no.
The check: ask the three people who spend longest in the room. Not the partners, and not the patients.

DIFFERENCE THREE · WHAT THE ROOM IS SIGNALLING
Reception is judged on care; a clinical room is judged on competence
The two rooms do different jobs for your practice and are read differently as a result. A waiting room is the one part of an eye clinic that is allowed to be hospitable, because nothing clinical happens in it. Restraint there reads as attention to detail, the same register as clean upholstery and good light. An examination room is read for competence, and a hospitality signal inside it competes with that reading rather than adding to it. It is also why the correct intensity in a clinic is lower than in any retail or hospitality setting: lower than a salon, lower than a showroom, materially lower than a hotel lobby. If a visitor can name what the waiting room smells of, it is too strong for the building you are in.
Part two — the two rooms compared on ten counts
Here they are side by side. The point is not that the examination room loses on one count; it is that every variable resolves the same way, which is what distinguishes a genuine boundary from a preference somebody will relitigate in six months.
Reception vs examination room · ten variables
Not one of these ten has the same answer in both rooms
| The variable | Reception and waiting | Examination room | What that decides |
|---|---|---|---|
| Why the person is in the room ★ | They arrived and have not been called yet | They were sent, as a step in the clinical visit | Arrival is hospitality space; everything caused by the visit is clinical space |
| Whether they can decline the room's air | Yes — they can change seats or step outside | No — they are positioned at an instrument and asked to hold still | Ambience is only defensible where opting out costs nothing |
| Typical patient occupancy | 15–45 minutes, often longer at a busy clinic | 6–12 minutes per patient, repeated all day | Sets the dose in reception; rules the cabin out entirely |
| Staff occupancy of the same air | The desk team, all day, in a large shared volume | One clinician, all day, in a small closed volume | The cabin concentrates exposure onto one employee |
| Door state during the working day | Open to the street and to the waiting bays by design | Closed, or closed for the working part of the visit | A closed small room holds a constant; a lobby dilutes one |
| Distance between people | Chairs, a counter, a metre or more | Face to face across an instrument at arm's length | Close-range work is not a setting for an added constant |
| Equipment and records present | A desk, a queue screen, files behind the counter | Optics, electronics, calibrated instruments | Ultrasonic machines add humidity — a second reason to keep them out |
| What the patient's eyes are doing | Reading, waiting, looking at a phone | Under examination, often dilated, sometimes after drops | Not a claim about harm — a reason the practice, not a brand, decides |
| Whether a clinical decision is being taken | No — the room is administrative and social | Yes, continuously, and it is the room's entire purpose | Ambience must not compete with the competence signal |
| Who owns the decision about the room | The practice, as a hospitality choice, with staff consulted | The practice and its clinicians, as clinical judgement | SOSA specifies the first and declines to advise into the second |
| The honest caveat: this is an ambience comparison and nothing more, and not medical, clinical or regulatory advice. No SOSA product is described as safe or as unsuitable for any patient group, procedure or room, and no claim is made that fragrance harms or benefits anyone. Occupancy figures are typical ranges and will differ in your practice. Clinical policy, infection control, ventilation standards, accreditation and patient suitability rest entirely with the practice and its clinicians. | |||

The SOSA principle
A boundary that survives is one where every variable agrees. If a rule holds on nine counts and fails on the tenth, somebody will eventually find the tenth and argue from it.
The reception-versus-cabin split has no tenth to find.
Part three — the four arguments for scenting an examination room, answered
Four versions of the case for putting something in a clinical cabin come up regularly, and all four sound reasonable. The first is that a smaller product is a smaller decision. A 50ml reed bottle looks so modest on a windowsill that it does not feel like a policy — and that is exactly how it ends up in rooms nobody agreed to. Format is not scale. A reed diffuser is constant, passive and has no off switch, so a bottle in a small closed cabin is a twenty-four-hour decision with no way to interrupt it short of carrying it out of the building. The second is "only between patients", usually proposed with a timer. Air does not clear on the schedule a timer implies; a small closed room holds what has been put into it, and the next patient walks into the tail of it. A timer controls when a zone is scented, not whether a clinical room becomes temporarily eligible.
The third is that the cabin smells of something else, and fragrance would deal with it. This is where the whole category oversells itself. Fragrance adds a scent alongside what is already in the air. It removes nothing. It does not mask, neutralise, purify, sanitise or clean, and layering a composition over a cleaning agent or a stuffy afternoon produces a third smell worse than either of the two you started with. If a cabin smells of disinfectant, that is a cleaning-protocol and ventilation question for your housekeeping supervisor and your clinicians. If it smells closed, it is under-ventilated, and more fragrance in an under-ventilated room reads as heavier rather than fresher. The order never changes: find the source, fix the ventilation or the cleaning, and only then — and only in the arrival zone — consider fragrance. The fourth is that a premium practice should feel premium throughout. It should, and the way a clinical room does that is with good light, quiet equipment, clean surfaces and a technician who explains what is about to happen.
There is a fifth position that is not an argument but a situation, and it decides whether this page applies to you at all. If your consultation cabins open directly onto the waiting area, or their doors are propped open all day, you do not have two rooms — you have one volume with a partition in it. In that building the reception decision is silently a clinical decision, and the honest move is to change the door before spending anything on fragrance. A self-closing hinge costs a few hundred rupees and is the most useful thing on this page. Where that is not possible, leave the building unscented for now and revisit after the next refurbishment.
A smaller bottle is not a smaller decision. If a room is out of scope, it is out of scope in every format, at every setting, at every hour.
— Sonal Sahani, SOSA
Part four — what reception actually costs, worked out
Having ruled out most of the building, the remaining question is small and answerable: what the one room in scope costs to run. The examination rooms are a ₹0 line in every row below.
The in-scope room, priced — with the arithmetic shown
Six reception situations, what each needs, and the weekly cost
| Your reception and waiting zone | What I would put in it | Setting or reed count | Cost, with the arithmetic |
|---|---|---|---|
| Every examination room, cabin and lane ★ | Nothing, in any format | Not applicable | ₹0 — and this row is the point of the page |
| Under ~100 sq ft — a desk and four or five chairs | One 50ml reed bottle, on a tray, away from the corridor mouth | Start at four reeds of six, not six | ₹749 over 6–8 weeks ≈ ₹94–₹125 a week (₹749 ÷ 8 = ₹94; ₹749 ÷ 6 = ₹125) |
| ~100–150 sq ft — a small clinic front of house | One 130ml reed bottle for the longer plateau, not for more reach | Six reeds, flipped weekly with gloves | ₹1,249 over 14–18 weeks ≈ ₹69–₹89 a week (₹1,249 ÷ 18 = ₹69; ₹1,249 ÷ 14 = ₹89) |
| ~150–320 sq ft — the commonest Indian arrival zone | Sukoon, behind the desk line, far end from the corridor | Lowest setting, 2H or 4H timer rather than steady | ₹1,899 once, three 15ml fragrances in the box; a 100ml Hotel Collection refill is ₹999, so ₹1,899 + ₹999 = ₹2,898 for the opening kit |
| ~320–800 sq ft open reception, or two connected waiting bays | Vaayu, freestanding only — never wall- or HVAC-mounted in a clinic | Lowest intensity, run window set to opening hours, key-lock on | ₹11,999 · under 38 dB · 400ml in the box lasts roughly 90+ days — confirm refill supply first |
| Three branches wanting the same reception scent | Three identical machines rather than one large one per site | Same setting written down and locked at each site | ₹1,899 × 3 = ₹5,697 · no bulk price, slab or account is published — ask before assuming one |
Honest notes for buyers: nothing on this page is medical, clinical or safety advice, and no SOSA product is described as safe or unsuitable for any patient group or any room — that judgement belongs to the practice and its clinicians. A diffuser adds a scent to the air; it does not clean, purify, filter, sanitise or disinfect air, and it does not remove disinfectant, damp, stale or occupancy smells. No claim is made about comfort, anxiety, perceived waiting time, recovery, ratings, enquiries or revenue. Some people are sensitive to airborne fragrance, which is why the clinical pathway stays fragrance-free and a fragrance-free seat should always exist in the waiting area. A 50ml reed bottle lasts 6–8 weeks and a 130ml 14–18 weeks; size buys duration, never reach. Oil-only refills are 300ml ₹2,399 and 500ml ₹3,499, and reeds are not sold separately. Reed oil cannot go in an ultrasonic machine and water-based Hotel Collection cannot go in a reed bottle. Ultrasonic machines add humidity; the waterless Vaayu does not. Coverage figures are manufacturer specifications and vary with ceiling height, air exchange and occupancy. SOSA does not currently sell a separate Vaayu cold-air refill oil — the 400ml supplied in the box runs roughly 90+ days at a mid setting, so a practice planning continuous or multi-site use should confirm current refill availability before committing; the water-based Hotel Collection is not a Vaayu refill. No bulk pricing, corporate account, maintenance contract, installation service, warranty term, delivery window or multi-site programme is published — ask through the contact page first.

For a compact arrival zone, and nowhere past the corridor
Morning Freshness · Malabar lemon · peppermint · Nilgiri eucalyptus ₹749 / 50ml · ₹1,249 / 130ml
Clean and bright rather than sweet, which is the right register for a room whose job is to look competent. It sits at 9.0 on SOSA's own internal ten-point scale at six reeds — a house scale, not an industry standard and not a quality ranking. In a clinic reception I would start it at four reeds and add the fifth only if a visitor coming in from the street cannot tell the room has anything in it at all. Alcohol-free, phthalate-free and IFRA-compliant on a heat-stable coconut-derived carrier, with six fibre reeds rather than rattan because rattan clogs in Indian humidity. Stand it on a tray — the oil marks wood and stone — keep it out of direct sun and away from a draught, and out of reach.

A note from Sonal
The first eye practice that asked me this question asked it the other way round. They had already put a small bottle in each consultation cabin — one per doctor, chosen by each doctor — and reception had nothing at all, because nobody had thought of it as a room.
One conversation with an optometrist explained why that was exactly the wrong answer. She said something I have quoted ever since. "I am in that room for nine hours. My patient is in it for nine minutes. Why does the nine-minute person get to choose what I breathe?" Nobody had asked her. Nobody asks the people who work in the room, because the question always gets framed as being about patients — and the patients are the ones with the shortest exposure and the most polite instinct to say nothing.
We moved everything to the front of the building, at a lower level than they had been running in the cabins, and left the clinical side alone. That is the whole recommendation and it has not changed since. I would rather sell one bottle for a reception than six for a corridor of cabins. Composed and made in small batches in Pune, and a part of every order funds a girl's classroom through Nanhi Kali.
Frequently asked questions
Could we use a much weaker fragrance in the examination rooms rather than none?
No. The argument for keeping a clinical room clear is not that fragrance at normal strength is too strong for it; it is that an ambient decision is not appropriate in that room at all, because the person in it cannot decline and the person who works in it is exposed all day. A weaker version of an inappropriate decision is still the decision. What practices asking this usually want is for the cabins to feel less stuffy — a ventilation question, with a different answer and a different supplier.
Our consultation cabins open straight onto the waiting area. Where is the boundary then?
You do not have one yet, and I would fix that before buying anything. A cabin whose door stands open shares its air with the waiting room, so anything in the waiting room is in the cabin. A self-closing hinge costs a few hundred rupees and is the most useful spend on this page. If the layout genuinely cannot change, leave the building unscented rather than running a lower setting and calling it a compromise.
What about the doctor's own cabin — surely that is their room to decide?
Their room, yes, but not only their room: patients are examined in it, a technician often works in it, and it sits on the clinical corridor. Cabins take nothing regardless of whose name is on the door, and a practice that allows one exception has in effect allowed all of them, because the next doctor will reasonably ask why not.
How strong should the reception itself be?
Lower than you think, and materially lower than a salon, a showroom or a hotel lobby. The test: someone walking in from the street should register the room as pleasant without being able to name what they are smelling. Set it for the person at the desk for eight hours rather than for the first ten seconds of a visit, and remember your own nose adapts to your own building within minutes — so ask a visitor, or start at four reeds instead of six.
Our clinic is 1,100 sq ft in total. Does that mean we need a Vaayu?
Almost certainly not, because you are not scenting 1,100 sq ft. Subtract the cabins, the lanes, diagnostics, the procedure room and the stores, and what is left is an arrival zone that in most Indian practices measures 150 to 320 sq ft. That is Sukoon territory at ₹1,899. The Vaayu earns its ₹11,999 only when the open arrival zone itself runs past roughly 320 sq ft — and even then it goes freestanding in reception, never mounted into shared air-conditioning.
Eye clinics · the clinical boundary
Reception, yes. The examination room, no — in every format, at every setting.
The two rooms differ on ten counts and every one resolves the same way. Reception is hospitality space; everything past the consultation door is clinical space and takes nothing. Size to the arrival zone, not the clinic — reeds from ₹749 under about 150 sq ft, a Sukoon at ₹1,899 from 150 to 320 sq ft, a freestanding Vaayu at ₹11,999 only past that, under 38 dB, key-locked and never mounted into shared HVAC. A diffuser adds a scent to the air; it does not clean or purify air, remove any existing smell, or have any clinical effect. Free shipping above ₹499.

Editorial standards & sources
About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. It compares an eye clinic's reception and its examination rooms as ambience decisions only, and concludes that reception is in scope while every clinical room is not. Nothing in it is medical, clinical or regulatory advice; no clinical outcome, patient response, safety property or business result is claimed for any product, and no product is described as harmful or as safe in any clinical setting. Occupancy ranges are typical rather than measured and vary between practices. No competitor is named or rated, and no hotel group is a SOSA customer, partner or reference.SOSA range, specifications and prices used in this guide (verified August 2026): Vaayu ₹11,999 — waterless cold-air nebulisation of undiluted fragrance oil; no water, no heat, no added humidity, no white mineral dust. Coverage up to 1000 m³, about 2,000–3,000 sq ft. 400ml refillable tank lasting roughly 90+ days at a mid setting. Bluetooth app plus onboard controls, 1h / 4h / 8h / 24h run windows, day selection, adjustable intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. Freestanding or wall / HVAC mount. 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.
