Founder Diaries · Eye Clinic Scenting · What It Should Smell Like
Reception and waiting are the only zone in scope — and you size to that zone, not to the clinic. A 900 sq ft practice is usually a 150–200 sq ft scenting job. For most Indian eye clinics the sized product is a Sukoon at ₹1,899 on its lowest setting, or a reed diffuser from ₹749 under about 150 sq ft.
The register is dry, low and unremarkable. Nothing sweet, nothing gourmand, nothing floral-heavy, nothing that reads as a spa. A clinic is judged on competence, and ambience must never compete with that signal.
What this page will not claim: fragrance does not calm anyone, shorten a wait, aid recovery or signal care. Some people are sensitive to airborne fragrance — which is why the clinical pathway stays clear, why a fragrance-free seat should always exist, and why the practice, not SOSA, sets its policy.
Vaayu waterless₹11,999 · under 38 dBRetail scenting is designed for a visit of a few minutes; an eye clinic is not that. People sit in your waiting area for a long stretch and staff sit in it all day. A level that seems faint on walking in is a great deal more than faint by the fortieth minute, and it is the fortieth minute that defines the room. Two consequences follow. Set the intensity to the lowest position at which anything registers at all, then leave it a fortnight before touching it. And ask the front desk — they are the only reliable instrument you have, because your own nose adapts to your own building within minutes of walking into it. A key-lock matters here for an unglamorous reason: it stops the setting drifting upward every time someone decides the room smells of nothing.

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.

Prices subject to change — see the live product pages.
Before the scent question there is a different one, and getting the order wrong is the commonest mistake in this subject. A premium eye clinic should smell of nothing at all through its clinical pathway — examination rooms, diagnostics, consultation cabins, the procedure suite and any post-operative area — and at most of something very low and very dry in reception and waiting. That is a zone answer, and it comes before any conversation about notes. Reception and waiting are hospitality space; everything past the consultation door is clinical space, and nothing I sell belongs in it. Once that boundary is drawn the honest target for the arrival zone is narrow: considered, not scented. A room that has clearly been thought about, in which no one is meant to be able to name a fragrance.
Quick answers — read this first
The clinical pathway stays fragrance-free. Examination rooms, refraction and diagnostic areas, consultation cabins, the procedure suite and post-operative space get nothing. Every recommendation below sits inside that.Reception and waiting are the only zone in scope — and you size to that zone, not to the clinic. A 900 sq ft practice is usually a 150–200 sq ft scenting job. For most Indian eye clinics the sized product is a Sukoon at ₹1,899 on its lowest setting, or a reed diffuser from ₹749 under about 150 sq ft.
The register is dry, low and unremarkable. Nothing sweet, nothing gourmand, nothing floral-heavy, nothing that reads as a spa. A clinic is judged on competence, and ambience must never compete with that signal.
What this page will not claim: fragrance does not calm anyone, shorten a wait, aid recovery or signal care. Some people are sensitive to airborne fragrance — which is why the clinical pathway stays clear, why a fragrance-free seat should always exist, and why the practice, not SOSA, sets its policy.
The short answer
Short answer: like clean, moving air almost everywhere, and at reception like a dry, low, woody-green note no one can name. One source, arrival zone only — a Sukoon ₹1,899 for a 150–320 sq ft reception, a reed diffuser ₹749–₹1,349 below that, a freestanding Vaayu ₹11,999 only past roughly 320 sq ft of connected public area.
Why the zone comes first: a clinic is not one room. It is a hospitality space and a clinical space sharing a door, and the only defensible position is to keep them separate. Placement, air path and door discipline therefore matter more here than the choice of scent — and a diffuser should never be ducted into shared air-conditioning in a clinical building.

Straight answer
What should a premium eye clinic actually smell like?
1. Through the clinical pathway, of nothing. Examination rooms, refraction and diagnostic areas, consultation cabins, dilation bays, the procedure suite and every post-operative space stay fragrance-free. Not a hedge and not a legal footnote — it is the first design decision, and everything else here depends on it holding.
2. At reception, of a dry low note nobody can name. The target is a room that reads as considered rather than scented. If a visitor can identify the fragrance, it is set too high. That is a statement about calibration, not about anyone's experience.
3. Size to the arrival zone, never to the clinic. The number that matters is reception plus waiting — in most Indian eye clinics 150–400 sq ft, even when the practice occupies three times that. A Sukoon at ₹1,899 covers 270–320 sq ft and is the right answer far more often than anything expensive.
4. Set the level for the receptionist, not the visitor. Your front-desk staff sit in that air for eight or nine hours; a patient is there for part of a morning. Any intensity that is wrong for the person at the desk is simply wrong, and they are the only people in the building worth asking.
5. Keep a fragrance-free seat, always, and never mount a diffuser into shared air-conditioning. Some people are sensitive to airborne fragrance, so a practice that scents its reception should be able to seat someone where the fragrance does not reach. And ducting scent into central AC sends it to every room the system serves, including the ones that must stay clear. Freestanding in reception, set back from the corridor to consultation.
6. Nothing here is clinical advice. Ventilation standards, infection control, cleaning protocol and patient suitability rest entirely with you and your clinicians. I compose fragrance and I can tell you how a room behaves; the medical judgement is not mine to make.

TL;DR: fragrance-free through the whole clinical pathway; a dry, low, unnameable note in reception only. Size to the arrival zone — a reed diffuser from ₹749 under 150 sq ft, a Sukoon at ₹1,899 to 320, a freestanding Vaayu ₹11,999 above that. Never into the AC. Always a fragrance-free seat.
The machine most eye clinics actually need
SOSA Sukoon · 500ml ultrasonic, 270–320 sq ft ₹1,899
A 500ml ultrasonic machine covering 270–320 sq ft, which is the size of most Indian eye clinic receptions once you stop counting the consulting rooms. Sixteen to eighteen hours on low, a remote, and steady / 2H / 4H timers so it is not running through a quiet afternoon. Three 15ml Hotel Collection fragrances are included — water-based, made for ultrasonic machines, and inspired by the atmosphere of well-known hotels; SOSA is an independent Indian brand, unaffiliated with any hotel group. Being ultrasonic it adds a little humidity, worth knowing before siting it near paper records or equipment.
Part one — the three decisions, in order
Almost every clinic that gets this wrong got the order wrong rather than the products: a fragrance, then a machine, then a decision about where to put it — by which point the important decision had already been made badly. The sequence that works is zone, then dose, then scent, and the third matters least.
1
DECISION ONE · WHERE THE BOUNDARY SITS
Draw the line at the consultation door and defend it physically
A clinic is two buildings sharing a door. On one side is arrival: the entrance, the desk, the seating, sometimes an optical display. On the other is everything the practice exists to do. Fragrance belongs entirely on the first side, and the boundary has to be held by physics rather than by intention. The source sits several metres back from the corridor mouth rather than beside it; it does not face the corridor; it is never inside the return-air path of the central system; and in a clinical building it is never mounted into the ducting. A source in the middle of a reception behaves very differently from the same source two feet from an open corridor, and the difference is entirely in where the air goes next. If the floor plan does not allow that separation — a reception that is really a wide piece of corridor — the honest answer is to scent nothing.
The rule: if you cannot describe, in one sentence, where the air from the source goes next, do not switch it on.

DECISION TWO · THE DOSE, SET FOR THE LONG EXPOSURE
Calibrate for the fortieth minute and for the person at the desk all day
Vaayu waterless₹11,999 · under 38 dBRetail scenting is designed for a visit of a few minutes; an eye clinic is not that. People sit in your waiting area for a long stretch and staff sit in it all day. A level that seems faint on walking in is a great deal more than faint by the fortieth minute, and it is the fortieth minute that defines the room. Two consequences follow. Set the intensity to the lowest position at which anything registers at all, then leave it a fortnight before touching it. And ask the front desk — they are the only reliable instrument you have, because your own nose adapts to your own building within minutes of walking into it. A key-lock matters here for an unglamorous reason: it stops the setting drifting upward every time someone decides the room smells of nothing.
The correct intensity in a clinic is lower than in a salon, a showroom or a hotel lobby — materially lower, not slightly.

DECISION THREE · THE REGISTER, WHICH IS THE EASY PART
Dry, green, woody or clean-neutral; nothing sweet, nothing that reads as a spa
Once the first two decisions are made the scent choice narrows to almost nothing, which is a good sign. What tips a medical building into feeling like a spa is warmth, sweetness, floral weight and any visible plume of diffusion — avoid all four rather than searching for a clever composition. In the SOSA reed range that points at Mountain Breeze, Himalayan pine and sage over Indian cedar, and at Morning Freshness, Malabar lemon, peppermint and Nilgiri eucalyptus, which reads clean rather than sweet. It points away from Fresh Brew — coffee and vanilla, a lovely thing in a living room and entirely wrong in a waiting area. The strength numbers SOSA publishes are positions on our own internal scale at six reeds, not an industry standard and not a concentration.
Part two — the zone map, room by room
Here is the map I would hand a practice on day one. It is deliberately blunt: most of this building gets nothing, and the parts that get something get very little.
The zone map · hospitality space and clinical space
Every room in a typical eye clinic, with a yes or a no
| Zone | Scented? | Why | What goes there |
|---|---|---|---|
| Entrance and reception desk ★ | Yes — at the lowest workable level | Hospitality space; the one part of the building whose job is arrival | One source, freestanding, set back from the corridor |
| Waiting seating | Yes — the same source, the same level | Shares air with reception; a gradient inside one connected space cannot be held | Nothing additional. One zone, one scent, one setting |
| Optical and eyewear display, if it opens off reception | Yes, conditionally | Genuinely retail — but only if its air does not reach the clinical corridor | The same scent, at most a touch higher. Never a second fragrance |
| Corridor to consultation | No | It is the boundary. Whatever sits in this corridor arrives in the cabins | Nothing — and keep the source well back from its mouth |
| Consultation cabin | No | Clinical space. The conversation there should carry none of our ambience | Nothing |
| Refraction and diagnostic rooms | No | Long occupancy, equipment, staff working close to patients | Nothing |
| Dilation waiting bay | No | It looks like waiting but sits on the clinical pathway | Nothing |
| Procedure suite and post-operative area | No | The clearest clinical space in the building, and not my question to answer | Nothing |
| Staff room and back office | The practice's own call | Not a patient space — but it is your team's air for nine hours | A reed diffuser if they want one; ask them, not the patients |
| Patient WC | No product from us | A smell there is a cleaning and extraction question, and fragrance answers neither | Nothing. Fix ventilation and cleaning first |
| The honest caveat: this map is an ambience recommendation, not clinical guidance. Whether any fragrance at all is appropriate in your building — given your caseload, ventilation and protocols — is a decision for you and your clinicians, and a practice that reads this table and scents nothing has read it correctly. | |||

The SOSA principle
A clinic is judged on competence, and ambience must never compete with that signal. The target is considered, not scented — and the way to hit it is to under-dose a dry note in one zone and leave the rest of the building alone.
Which is why the honest answer here is usually a smaller product than the one the practice came looking for.
Part three — when a clinic should not do this at all
There are practices I would talk out of this entirely, and I would rather do it here than after the invoice. The first is any clinic whose reception is small and poorly ventilated. If the front of the building already smells closed by mid-afternoon, adding fragrance makes it heavier rather than fresher — you have given the room two things to carry instead of one. That is a ventilation problem with a ventilation answer, and it costs nothing to test. Fragrance is the last layer in a room that is already right, never a correction to one that is not.
The second is a children's eye clinic or any practice with a large paediatric caseload, and that is close to an outright no. Children cannot reliably report that something in a room is bothering them, parents are watching, and nothing is gained that would justify the asymmetry. The third is a practice whose real complaint is a disinfectant or cleaning smell. Fragrance does not cover, cancel or remove that — layering a composition over a cleaning product produces a third smell worse than either. If that is your question, the right outcome of reading this page is that you buy nothing today.
The fourth is about supply. If what you want is a signature — one recognisable scent held constant across every visit and eventually across several branches — you are making a commitment that depends on buying the same oil for years. There is a live gap to be straightforward about: SOSA does not currently sell a separate cold-air refill oil for the Vaayu. The 400ml supplied in the box lasts roughly ninety days or more at a mid setting and is the whole supply available at the time of writing. For a home that is an inconvenience; for a practice building an identity on one scent it is a business problem. The water-based Hotel Collection is not a substitute — it is made for ultrasonic machines and must not be used in a Vaayu. Confirm current refill availability through the contact page before committing a practice to a Vaayu.
Hospitality space and clinical space are two different buildings that happen to share a door. Everything sensible in this subject follows from keeping them separate.

Part four — what to specify, by arrival zone
Measure reception plus waiting and ignore the rest of the floor plan. Two of the rows below end in spending nothing.
Sized to the arrival zone
Seven arrival zones, seven specifications
| Your arrival zone | What I would specify | Cost | Why not the next size up |
|---|---|---|---|
| Under ~150 sq ft reception, quiet practice ★ | One Mountain Breeze 130ml, six reeds, on a tray away from seating | ₹1,349 · 14–18 weeks | An active machine here is over-specified and harder to keep low |
| ~150–320 sq ft reception and waiting | Sukoon on its lowest intensity, 4H timer, sited behind the desk line | ₹1,899 · three 15ml fragrances included | This is the sized product. A Vaayu at this volume is simply wasted money |
| ~320–800 sq ft open reception, or two connected patient zones on one air path | Vaayu, freestanding, lowest intensity, run window set to opening hours, key-lock on | ₹11,999 | Under 38 dB and schedulable — but confirm refill supply before committing |
| An eye hospital with 3,000+ sq ft of connected public area | Aangan, specified with your facilities team, public areas only | ₹25,999 | Beyond ~10,000 sq ft the range continues at Meenar ₹38,500 |
| You want the optical display to read slightly warmer | The same scent, a second small source, only if optical has its own air path | ₹749–₹849 on top | Two scents in one air path become one muddled scent |
| Reception smells closed by afternoon | Nothing yet. Ventilation, then re-test the room in a fortnight | ₹0 today | Fragrance in an under-ventilated room reads heavier, not fresher |
| Children's eye clinic or a large paediatric caseload | Nothing. This is the one I would decline outright | ₹0 | Nothing is gained that would justify it, and I would rather say so |
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 — that judgement is the practice's. A diffuser adds a scent to the air; it does not clean, purify, filter, sanitise or disinfect air, and does not remove disinfectant, damp or occupancy smells. No claim is made about comfort, anxiety, waiting time, recovery, ratings 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. Coverage figures are manufacturer specifications and vary with ceiling height, air exchange and occupancy. Megh at ₹3,499 covers about 215 sq ft — less than a Sukoon — so it is a runtime machine, never a coverage upgrade. Safar at ₹3,999 is a car and travel diffuser with no published coverage figure. SOSA sells no room spray; every SOSA spray is a car perfume. SOSA publishes no bulk pricing, corporate account, maintenance contract, installation service or stated warranty term — ask through the contact page before committing. Free shipping above ₹499.
The least spa-like composition in the range
SOSA Mountain Breeze · Himalayan pine, sage & Indian cedar ₹849 / 50ml
Of the five reed compositions this is the one I would put in a small clinic reception. Pine and sage over Indian cedar: dry, green and woody, with no sweetness and no floral weight. Six fibre reeds rather than rattan, because rattan's pores clog in Indian humidity; alcohol-free, phthalate-free and low-VOC on a heat-stable coconut-derived carrier. 50ml runs 6–8 weeks, 130ml ₹1,349 runs 14–18 weeks. In a clinic, stand it on a tray out of reach — the oil marks stone and wood, there is no off switch, and reed count is the only volume control you have.

A note from Sonal
The first time an ophthalmologist wrote to me about her reception, she did not ask which fragrance to buy. She asked whether she should be doing this at all. That is the correct first question, and I have never had a better one from a home customer. Her speciality is the organ that volatile compounds irritate, and she was not going to accept a cheerful answer.
What I told her is what this page says. Some people are sensitive to airborne fragrance. That is not a reason to pretend otherwise, and not a reason to make a safety promise I have no standing to make — it is the reason the clinical pathway stays clear, the reason the dose in an arrival zone is lower than in any shop or lobby, and the reason a fragrance-free seat exists before the machine is switched on.
I have also learned to say the unprofitable half out loud. Several practices that have written to me should not scent anything yet — a paediatric caseload, a reception with no real air exchange, a cleaning smell that fragrance would only complicate. Saying so costs the sale and keeps the recommendation worth something to everyone else. Made in Pune in small batches, and a part of every order funds a girl's classroom through Nanhi Kali.
Frequently asked questions
Should any part of an eye clinic beyond reception be scented?
No. Examination rooms, refraction and diagnostic areas, consultation cabins, dilation bays, the procedure suite and post-operative areas stay fragrance-free. Reception and waiting are the only zone in scope; an optical display can be included where it opens off reception and its air does not reach the clinical corridor. Whether even that is appropriate in your building is a clinical judgement that belongs to you.
Can I run a scent machine through the clinic's central air-conditioning?
Not in a clinic. The Vaayu can be freestanding or mounted, but ducting fragrance into shared air-conditioning distributes it to every room the system serves, including the ones that must stay clear. Freestanding in reception, set back from the corridor, is the correct placement. If an architect or supplier proposes an HVAC integration in a clinical building, decline it.
How strong should the fragrance be in a clinic reception?
Lower than you think, and materially lower than a salon, showroom or hotel lobby. Set it to the lowest position at which anything registers, leave it a fortnight, and ask the front desk rather than trusting your own nose — yours adapts to your own building within minutes. A key-lock is useful precisely because it stops the setting creeping upward over months.
Is a Vaayu the right machine for a 900 sq ft eye clinic?
Usually not, because you do not scent 900 sq ft. You scent reception and waiting, often 150–250 sq ft in a clinic that size, and a Sukoon at ₹1,899 covers 270–320 sq ft. A Vaayu at ₹11,999 earns its price where one connected public area runs past roughly 320 sq ft — and since no separate cold-air refill oil is sold at present, confirm current refill availability with SOSA before committing.
What if a patient tells us the reception fragrance is too strong?
Treat it as a measurement rather than an outlier: turn the setting down or switch the machine off that day, and seat that person where the fragrance does not reach. Having such a seat, and staff who know where it is, is part of doing this properly. Any decision about a specific patient is yours and your clinicians' alone.
Eye clinics · reception and waiting only
Considered, not scented — one low source in the arrival zone, and a fragrance-free clinical pathway
For a 150–320 sq ft reception the sized product is the Sukoon at ₹1,899 on its lowest setting. Above roughly 320 sq ft of connected public area, a freestanding Vaayu at ₹11,999 — under 38 dB, key-lock, scheduled run windows, never mounted into shared HVAC in a clinic. Under 150 sq ft, a reed diffuser from ₹749. 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.

Nothing in it is medical, clinical or regulatory advice; no clinical outcome, patient response, safety property or business result is claimed for any product. The zone recommendations describe where a fragrance product should and should not be placed, not who is suited to it. 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.
