Founder Diaries · LASIK Centre · Premium Without the Hotel Register
Premium in a medical building is a subtraction exercise. No clutter at the desk, no audible machine, no visible mist column, no scent anyone can identify — each one a thing removed rather than added.
Five things tip a surgical centre into the spa register: sweetness, resinous warmth, floral volume, visible or audible diffusion, and — the one nobody names — the lobby dose. Avoid all five and the composition question becomes small.
What this page will not claim: fragrance does not settle anyone before surgery, improve comfort, shorten a wait or affect recovery, enquiries or revenue. Some people are sensitive to airborne fragrance, which is why the surgical pathway stays clear and why your clinicians — not SOSA — set the policy.
Vaayu waterless₹11,999 · under 38 dBHalf the spa impression in most front halls is not olfactory at all. It is a column of mist rising off a machine on the counter, a faint hum from the same machine, and the machine sitting in the sightline like an ornament. Those are treatment-room cues, and they are read long before the composition arrives. An ultrasonic such as the Sukoon produces a visible cool mist and adds a little humidity, so it belongs behind the desk line rather than on it. The Vaayu nebulises undiluted oil without water and therefore without a mist column, runs under 38 dB, and can sit beside a joinery run where it is not part of the composition of the room.

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. Composed and made in small batches in Pune, India. 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 question is usually asked as a scent question and it almost never is one. A LASIK centre tips into feeling like a hotel or a spa because of its register — the overall pitch of the room — and register is set by dose before it is set by composition. The same dry cedar note at a lobby level reads as a lobby; at a fraction of that level it reads as a hall somebody has thought about. So the method is subtraction rather than selection: fewer objects, less noise, no visible plume, and a fragrance set so low that nobody can name it. All of that applies to the front of house alone. Everything past the consultation door — workup and diagnostics, counselling cabins, the pre-procedure area, the laser suite and every post-operative space — stays fragrance-free, which is the condition on which the rest of this page is offered.
Quick answers — read this first
Register is dose first, note second. A hotel lobby and a surgical front hall can run the same composition and read completely differently, because the lobby is set far higher.

The short answer
Short answer: keep one low source in the front of house, choose a dry woody-green note rather than anything warm or floral, and set it materially lower than a hotel would. A Mountain Breeze reed diffuser ₹849 under about 150 sq ft, a Sukoon ₹1,899 on its lowest setting to 320 sq ft, a freestanding Vaayu ₹11,999 above that. Nothing anywhere else in the building.
Why a surgical centre is the hardest case: a hotel wants you to notice its atmosphere. A refractive centre is asking a person to consent to an irreversible procedure on their eyes, and every signal in the room is read as evidence about the practice. An atmosphere that announces itself competes with the signal the building most needs to send.

Straight answer
How do you get premium without getting hotel or spa?
1. Set the dose first, and far lower than you think. What makes a room read as a hotel lobby is the level, not the composition. A note that is pleasant at a whisper becomes furnishing at a lobby setting, and furnishing is what a surgical building should not be doing with its air. Lowest position at which anything registers, then a fortnight untouched.
2. Remove the four visible cues before you touch the fragrance. A mist column at the entrance, a machine anyone can hear, a diffuser displayed like an ornament, and a counter with things on it. None of those four costs anything to fix.
3. Choose the register, then let the note follow. Dry, green, woody or clean-neutral; away from sweetness, resinous warmth and floral volume. That is why Mountain Breeze is my default here and Evening Calm is the accord I would most firmly keep out.
4. One source, one level, front of house only. A second fragrance reads as indecision and a stronger corner reads as an accident. Everything past the consultation door stays fragrance-free.
5. Size to the front hall, not to the centre. A 1,800 sq ft facility is usually a 200–350 sq ft scenting job once the rooms that must stay clear come out of the sum, and a Sukoon at ₹1,899 covers 270–320 sq ft.
6. Lock the setting and schedule the hours. A Vaayu gives 1h / 4h / 8h / 24h run windows, day selection, adjustable intensity and a key-lock, and runs under 38 dB. In a building with a theatre in it those are the specifications that matter: the level cannot creep up, and the machine is not running through a list.
7. Nothing here is clinical advice. Air handling, infection control, cleaning protocol and patient suitability rest with you and your surgical team; I compose fragrance and do not advise into your operating environment. Everything SOSA makes is made in small batches in Pune, and a portion of every order supports girl-child education through Nanhi Kali.

TL;DR: premium here is subtraction. Drop the level until the fragrance cannot be named, hide the machine, clear the desk, choose dry over warm — Mountain Breeze from ₹849, a Sukoon ₹1,899 on its lowest setting, a freestanding Vaayu ₹11,999 only past 320 sq ft. Front of house only.
The register a surgical front hall can carry
SOSA Mountain Breeze · Himalayan pine, sage & Indian cedar ₹849 / 50ml
Pine and sage over Indian cedar: dry at the top, grounded underneath, with no sweetness and no floral weight to pull it toward the spa end of the scale. Six fibre reeds rather than rattan, whose 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. Stand it on a tray well back from the corridor — the oil marks stone and wood, there is no off switch, and reed count is a bottle's only volume control.
Part one — what actually tips the register
Centres rarely arrive at the hotel or spa impression by choosing a hotel or spa fragrance. They arrive by copying a hospitality specification wholesale — the level, the machine, the placement, the visible object. Three things do the tipping, and only the third is about the bottle.
1
TIP ONE · THE DOSE, WHICH IS THE REGISTER ITSELF
The lobby setting is what makes a room read as a lobby
A hotel sets its lobby so a fragrance is unmistakably present within seconds of the door, because being noticed is the brief. Run the same composition at that level in a refractive centre and the building has borrowed a gesture it cannot support. The correct level in a clinical arrival hall is materially lower — not a notch, several. Set the machine to its lowest position, leave it a fortnight, then ask the person who sits at the desk all day rather than your own nose, which adapts to your own building within minutes. If a patient can identify the fragrance the level is wrong — a statement about calibration, not about anybody's experience.
The test: if someone could name the scent in a sentence, it is set for a lobby and not for a surgical centre.
2
TIP TWO · EVERYTHING THE ROOM CAN SEE AND HEAR
A visible plume or an audible machine is a spa cue before it is a fragrance
Vaayu waterless₹11,999 · under 38 dBHalf the spa impression in most front halls is not olfactory at all. It is a column of mist rising off a machine on the counter, a faint hum from the same machine, and the machine sitting in the sightline like an ornament. Those are treatment-room cues, and they are read long before the composition arrives. An ultrasonic such as the Sukoon produces a visible cool mist and adds a little humidity, so it belongs behind the desk line rather than on it. The Vaayu nebulises undiluted oil without water and therefore without a mist column, runs under 38 dB, and can sit beside a joinery run where it is not part of the composition of the room.
Under 38 dB matters more than any note: a front hall in which a machine is audible is worse than a front hall with no fragrance at all.
3
TIP THREE · THE COMPOSITION, WHICH IS THE SMALL PART
Sweetness, resinous warmth and floral volume are the three coordinates
Once the level and the hardware are right, the note choice is nearly settled by elimination. Sweetness reads as domestic, resinous warmth reads as hotel, and floral volume reads as spa — so a refractive centre wants a composition with none of the three. In the SOSA reed range that points at Mountain Breeze, Himalayan pine and sage over Indian cedar, and at low reed counts to Morning Freshness. It points away from Fresh Brew, a living-room register; away from Garden Bloom for floral weight; and most firmly away from Evening Calm, the most spa-coded accord I make. SOSA's strength figures are positions on our own internal scale at six reeds — not an industry standard, not a concentration and not a quality ranking. The range has no oud, no musk-forward composition and no aquatic.
Part two — the register scale, position by position
Stop thinking about scents and think about positions on a scale running from clinical to resort. Every building sits somewhere on it, and a refractive centre has two defensible positions.
The register scale · clinical at one end, resort at the other
Six positions, what puts a room in each, and how each reads in a surgical front hall
| Where a room sits | What puts it there | Where that register belongs | How it reads in a LASIK front hall |
|---|---|---|---|
| Considered — the target ★ | One low source, dry note, no visible plume, nothing nameable | The arrival hall of a surgical centre | As a room that has been thought about, without announcing it |
| Fragrance-free | No source at all, clean air and good housekeeping | The entire clinical pathway — and a perfectly legitimate front hall | As correct. It never reads as cheap, and several centres should stop here |
| Retail-warm | A warmer composition at a mid setting, deliberately noticeable | An optical or eyewear display with its own air path | As a shop that has wandered into a medical building |
| Hotel-lobby | Almost any note, run at hospitality level — the dose does it | A hotel lobby, where being noticed is the brief | As borrowed. This is the commonest single mistake in the category |
| Spa | Lavender or chamomile accords, soft florals, visible steam, low light | A treatment room | As the wrong kind of building entirely, and the hardest to walk back |
| Resort or gourmand | Vanilla, coffee, amber and resin warmth at any real level | A living room, a café, a lounge bar | As a distraction from what the facility is there to do |
| The honest caveat: this is a description of how registers are conventionally read, not a claim about what any fragrance does to anyone. No SOSA product is described here as calming, reassuring or clinically appropriate, and no claim is made about patient response, comfort, enquiries or revenue. Whether any fragrance at all belongs in your building is a judgement for you and your surgical team, and a centre that reads this table and chooses the fragrance-free row has read it correctly. | |||

The SOSA principle
In a hotel, atmosphere is the product. In a surgical centre, atmosphere is a background against which competence is being read. So premium here is reached by removing things — noise, clutter, visible apparatus, and most of the dose — rather than by adding a better fragrance.
Which is why the specification is nearly always smaller than the one the centre came looking for.
Part three — when a centre should not do this at all
Some centres arrive at this question with a problem fragrance cannot address, and I would rather say so here than after an invoice. The first is a centre whose premium problem is not olfactory in the slightest. When a hall feels ordinary despite an expensive fit-out, the causes are usually sound, light temperature, seating and clutter — a hard ceiling that returns every conversation at the desk, cold overhead light on white surfaces, and a counter carrying six objects. Fix that lot and the room changes. Add a fragrance instead and you have an unchanged problem with a scent on top. Fragrance is the last layer in a hall that is already right, never a correction to one that is not.
The second is a centre whose front hall already smells of something. Fragrance adds a scent alongside what is in the air; it removes nothing. It does not clean, purify, filter, sanitise or neutralise, and it will not deal with a disinfectant note drifting forward from the workup corridor, a damp patch behind the reception joinery, or the closed smell of a hall with no real air exchange. Layering a composition over any of those produces a third smell nobody designed. Find the source, fix the cleaning routine or the ventilation with the people who look after it, and come back when the hall smells of nothing at nine in the morning.
The third is a supply question, and it matters more in a centre than in a home. A recognisable hall — the same environment on the consultation visit, the treatment day and the day-one review — commits you to buying the same oil for years. SOSA does not currently sell a separate cold-air refill oil for the Vaayu. The 400ml in the box lasts roughly ninety days or more at a mid setting and is the whole supply available at the time of writing. In a flat that is an inconvenience; in a facility that has standardised a front hall it is a business problem with a visible failure mode. The water-based Hotel Collection is not a substitute — it is made for ultrasonic machines and must never go into a Vaayu; those scents are inspired by the atmosphere of well-known hotels, and SOSA is an independent Indian brand, unaffiliated with any hotel group. Confirm refill availability through the contact page before committing.
A hotel wants you to notice its atmosphere. A surgical centre is asking you to trust its judgement. Those two rooms cannot be furnished with the same dose.

Part four — the premium cue, and what to specify for it
Six things centres tell me they are chasing, the move that backfires in each case, and what I would specify instead. Two cost nothing at all.
Specified against the impression you are after
Six premium cues, and the version of each that survives a medical building
| The cue you are chasing | The move that backfires | What I would specify instead | Cost |
|---|---|---|---|
| A hall that feels considered the moment someone walks in ★ | A hospitality-strength diffuser on the counter | Sukoon on its lowest intensity, behind the desk line, with one 15ml Hotel Collection scent | ₹1,899 + ₹299 |
| Warmth at the front desk | Fresh Brew or any gourmand composition | Mountain Breeze 130ml, six reeds, on a tray away from the corridor | ₹1,349 · 14–18 weeks |
| Something that covers a 350–500 sq ft open front hall | Three reed bottles spread around the room | Vaayu, freestanding, lowest intensity, key-lock on, run window inside consulting hours | ₹11,999 · confirm refill first |
| Luxury cues borrowed from a hotel arrival | A visible mist column, a scented corridor, a machine on display | Subtraction: clear the counter, soften the acoustics, warm the light, hide the machine | ₹0 |
| A hall that feels alert rather than sleepy | Raising the level until the scent is obvious | Morning Freshness 50ml at four reeds, not six, well away from seating | ₹749 · shorter bottle life at any reed count above six |
| Covering a smell that is already in the hall | Anything at all from this page | Nothing today. Ventilation and cleaning first, then re-test the hall in a fortnight | ₹0 |
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, including post-operative patients — 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, waiting time, recovery, ratings, enquiries or revenue. Some people are sensitive to airborne fragrance, which is why the surgical 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 and humidity machine, never a coverage upgrade. Safar at ₹3,999 has no published coverage figure. Reed strength figures are positions on SOSA's own internal scale at six reeds, and replacement reeds are not sold separately. SOSA sells no room spray; every SOSA spray is a car perfume. SOSA publishes no bulk pricing, corporate account, maintenance contract, installation service, warranty term, delivery window or multi-site programme, and does not currently sell a separate Vaayu refill oil — ask through the contact page before committing.
The machine most front halls actually need — used quietly
SOSA Sukoon · 500ml ultrasonic, 270–320 sq ft ₹1,899
A 500ml ultrasonic covering 270–320 sq ft — the size of most vision-correction arrival halls once the surgical rooms come out of the sum. Sixteen to eighteen hours on low, a remote, and steady / 2H / 4H timers so it is not running through an operating session. 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 produces a visible cool mist and adds a little humidity — which is precisely why it goes behind the desk line, away from paper records and equipment.

A note from Sonal
A refractive surgeon once sent me photographs of a hall he had just finished and asked, quite bluntly, why it felt like a mid-range hotel when he had spent like a good one. There was a mist column on the counter, a marble reception desk carrying six objects, and a diffuser running at a level a lobby would have been pleased with. None of those was a fragrance problem.
We changed three things and none of them was the scent. The machine went behind the joinery; the level came down to the lowest position that registered at all; the counter was cleared to two objects. He wrote back a fortnight later to say the hall had stopped announcing itself — the outcome he had wanted and could not name.
In a surgical building the perfumer's job is mostly to argue for less. A hotel is allowed to be memorable. A centre performing an elective procedure on somebody's eyes is assessed, continuously, on whether it seems exact — and an atmosphere that competes for attention takes something from that. 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
Is there a fragrance that reads premium without reading like a hotel?
The question is better asked about level than about fragrance. A dry woody-green composition such as Mountain Breeze at a very low setting reads as considered; the same composition at a hospitality level reads as a lobby. Set the dose first; then avoid sweetness, resinous warmth and floral volume, and the choice narrows on its own.
Our designer wants a diffuser with a visible mist at the entrance. Is that a problem?
In a surgical centre I would avoid it. A visible mist column is a treatment-room cue, read before any fragrance arrives. An ultrasonic such as the Sukoon can still be used — behind the desk line, out of the sightline. The Vaayu nebulises undiluted oil with no water, so there is no mist column at all, and runs under 38 dB.
Can we use a hotel-inspired scent in a LASIK centre?
You can use the composition; you should not use the hotel's dose. The Hotel Collection is water-based fragrance for ultrasonic machines — 15ml ₹299, 100ml ₹999, 300ml ₹1,799 — and those scents are inspired by the atmosphere of well-known hotels. SOSA is an independent Indian brand, unaffiliated with any hotel group, and none is a SOSA customer or partner. Run whatever you choose at the lowest setting that registers.
Which SOSA scents would you keep out of a refractive centre entirely?
Evening Calm first — Kashmir lavender and chamomile is the most spa-coded accord in the range. Then Fresh Brew, because coffee and vanilla is a domestic, gourmand register, and Garden Bloom for floral weight. That leaves Mountain Breeze as the default and Morning Freshness as a low-dose alternative.
Should the consultation and procedure side share the front hall's scent, so the building feels consistent?
No. Consistency stops at the consultation door. Workup and diagnostics, counselling cabins, the pre-procedure area, the laser suite and every post-operative space stay fragrance-free, and a diffuser should never be ducted into shared air-conditioning in a building with a theatre in it. Freestanding in the front hall, well back from the corridor, is the only placement I would specify. Whether even the front hall is appropriate in your centre is your surgical team's judgement.
LASIK and vision-correction centres · the register question
Premium by subtraction — lower the dose, hide the machine, and keep the surgical half clear
Under about 150 sq ft of front of house, a reed diffuser from ₹749. From 150 to 320 sq ft, a Sukoon at ₹1,899 on its lowest setting, behind the desk line. Past roughly 320 sq ft, a freestanding Vaayu at ₹11,999 — under 38 dB, no mist column, key-lock, run windows set to consulting hours, never mounted into shared HVAC. Everything past the consultation door stays fragrance-free. A diffuser adds a scent to the air; it does not clean or purify air, remove any existing smell, or have any clinical effect.

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.
