Most of this bank treats a day-care hospital as two buildings sharing an address: a public half that is a genuine commercial opportunity and a clinical half that gets nothing. An endoscopy centre has a third element, and it has no equivalent in most day-surgery buildings. You run a dedicated reprocessing room, it has its own extraction, it has its own working atmosphere, and it is emphatically not a place for ambient fragrance. It is a technical working room, not a patient room and not a public room, and nobody's brand lives in it.
So this page is really about keeping the public half and the reprocessing half apart in air terms. That is a physical arrangement rather than a good intention, and it rests on the most useful fact in commercial scenting: a closed door ends one connected body of air and begins another. A facility's air handling can be arranged so the patient-facing rooms and the technical rooms are not one volume, and where that is already true your scenting plan is real rather than hopeful.
And one sentence that this page will repeat in several forms because it is where money gets wasted and credibility gets lost. If a smell is arriving in the corridor from the direction of reprocessing, that is a ventilation and extraction question for your facility's engineers, never a fragrance one. Fragrance adds scent. It does not remove odour, neutralise it, absorb it or mask it away. Putting a scent source in a corridor to deal with something coming out of a technical room gives you two smells instead of one, and the third impression they make together is worse than the original and tells every visitor that somebody knew.
The rest of the clinical boundary is unchanged. Procedure rooms, post-procedure and post-anaesthesia recovery, pre-procedure areas, sterile storage, clinical and drug storage and clinical waste get nothing. Not a lower setting. Nothing. And what may be introduced into the air of a building like yours is decided by your own clinical leadership, infection-control policy and facilities engineering, whose decision overrides every recommendation here.
A smell reaches our corridor from the reprocessing area. Can fragrance help? No. That is a ventilation, extraction and pressure question for your facility's engineers, and it has an engineering answer: extraction that runs and is maintained, doors that are not propped, and air moving in the direction the building was designed to move it. Fragrance adds scent and never removes odour, so a scent source in that corridor adds a second smell to the first. Never scent a corridor to deal with something arriving from a technical room, and never reduce ventilation anywhere so a fragrance lasts longer.
Where does the machine physically go in an endoscopy centre? In the waiting area or reception, inside the volume you intend to scent, facing into the room, away from the entrance draught, away from any return grille, and as far as the room allows from the door or corridor that connects toward the procedure and reprocessing side. Never in that connecting corridor, never ducted into air handling that serves a clinical zone, and never into an extract system. Placement near air handling is confirmed by your own engineers before anything is drilled.
Patient-facing non-clinical, and therefore scentable. The entrance and lobby. Reception and billing. The waiting area. The attendant or family seating. A consultation room used for talking rather than for procedures, if you have one at the front of the building. Public circulation that connects those rooms to each other and to the street. That is the list. It is short, and in most endoscopy centres it is a modest fraction of the built area, which means the purchase is smaller than most facilities expect. That is the correct answer arriving early rather than a disappointment.
Clinical, and therefore nothing. Pre-procedure areas, the procedure rooms themselves, post-procedure and post-anaesthesia recovery, sterile storage, clinical and drug storage and clinical waste. Not a lower setting, not a subtler register, not a reed somebody brought from home because a shelf looked bare. Nothing. Write it as a list of named rooms on the same drawing that carries the scenting plan, so that a well-meaning new supervisor in month seven does not helpfully add something.
The third category, which is why this page exists: the decontamination and scope-reprocessing area. It is not a patient area and it is not a public area. It is a technical working room with its own extraction, its own equipment and its own working atmosphere, and it gets nothing - not for patients, not for visitors, and not for the staff who work in it. That last point is worth making explicitly because it is the version of the mistake I actually encounter: somebody buys a diffuser for a technical room as a kindness to the team working there. Do not. Anything introduced into that room is an addition to an environment that is engineered and managed by other people for other reasons, and it is not a decision that belongs to a front-of-house budget or to a fragrance supplier. If the working environment in that room is unpleasant, that is a ventilation, extraction and equipment matter for your engineers and your clinical leads, and it deserves a proper answer rather than a bottle.
Then the transfer route between the procedure rooms and reprocessing, which in most units is a corridor or a dedicated pass-through. Whatever its arrangement, it is planned by your facility for reasons that have nothing to do with your brand, and it is not a place to put a machine. A corridor is a fifteen-second space connected to everything at both ends, and it is where scenting plans get broken, usually because that is where the free socket was.
So the working shape of the plan is: scent the front rooms, treat the connecting door as the edge of the scented world, and let the technical half be technical. When you look at it that way the endoscopy centre is not a harder building to scent than any other. It is simply a building where the boundary has to be drawn more carefully and where the person drawing it has to be able to name the rooms. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The most common way this goes wrong is not a bad register. It is a good register produced by a machine that somebody put in a corridor. The corridor is where the socket is, the corridor feels like the middle of the building, and a corridor is exactly the space that connects the two halves you are trying to keep apart. Put the unit in the room you intend to scent, facing into it, and accept that this may mean running a cable somewhere slightly less convenient or wall-mounting the unit.
The second most common is a plan that exists only in somebody's head. Principles get reinterpreted by new staff; a list of named rooms on a drawing does not. Write down which rooms are scented, which rooms are fragrance-free, what register is running, what the setting number is and who is allowed to change it. Tape a card to the machine. Put the fragrance-free room list in the facility SOP alongside everything else that is written down about the building.
Your staff are the check and in your speciality they are also the people most likely to notice a problem early, because they move between the front and the back of the building all day and their noses are recalibrated by each transition. The desk team, the housekeeping team and the nursing team are in that air for eight to ten hours. Ask them before you buy and again a fortnight after installation. If any of them mentions the scent, that is a recalibration signal rather than a tolerance problem, and switching a named unit off must be something anybody on the desk can do without finding a manager first.
And the honest commercial note. If your front of house is small - a reception and twenty chairs - this is a ₹1,899 decision and not an ₹11,999 one, and a page that tells you otherwise is selling rather than advising. The Vaayu earns its price where the connected public volume is large, where the building must run on a timer all day without anybody touching the machine, and where waterless operation is the reason a facility will consider scenting at all.
Three halves, not two: public, clinical, and the reprocessing room
Three things decide this, and none of them is the fragrance. The first is the room list: which rooms are patient-facing and non-clinical, written by name rather than described by principle. The second is air separation: whether the front rooms and the technical rooms are, in physical fact, one connected body of air or two. The third is what you do when something arrives from the wrong direction, which is the question this speciality asks more often than any other and which has an engineering answer rather than a fragrance one.
What does not decide it: any ranking of the seven registers on throw or longevity. SOSA does not publish that comparison and this page will not invent one. Connected volume, ceiling height, ventilation rate, door traffic, occupancy and the setting on the machine will move your result far more than the difference between one blend and another.
So do the arithmetic on the rooms you can actually scent, and say what ceiling you assumed, because hospital lobbies are commonly 10 to 14 feet and some entrances are double height. A 600 sq ft waiting area at 12 ft is 600 x 12 = 7,200 cubic feet, and 7,200 / 35.3 is about 204 cubic metres. A 400 sq ft reception at 11 ft is 4,400 cubic feet, about 125 cubic metres. A 1,000 sq ft connected front of house at 11 ft is 11,000 cubic feet, about 312 cubic metres. A 1,500 sq ft public floor at 12 ft is 18,000 cubic feet, about 510 cubic metres. Against the SOSA Vaayu at ₹11,999 and its rating of approximately 1000 cubic metres of connected air, the honest finding is the one this bank keeps arriving at: the volume that genuinely needs scenting is small, so the purchase is smaller than expected.
Notice which number is absent from that paragraph. The reprocessing room has a volume, and it is not in your calculation, because it is not part of your scented volume at any setting. The same goes for the procedure rooms, recovery, storage and waste. Your scented volume is the front rooms alone, full stop, and the arithmetic should reflect the plan rather than the building.
One more piece of physics that belongs to this speciality. The connecting door between the front and the back is not a wall. It is opened and closed all day, it may have an undercut, it may sit in a corridor that behaves like a plenum between two zones, and the rooms on either side of it may share a return grille or an air handler even when the drawing shows them as separate. Those are the four mechanisms by which a perfectly reasonable scenting plan produces fragrance somewhere it should not be, and every one of them is a question for your own facilities engineers and HVAC consultant rather than for a page. A scenting unit is never ducted into air handling that serves a clinical zone, and never into an extract system.
Everything below is about rooms, doors and air. Nothing here is clinical, infection-control or engineering advice, no SOSA product is a medical device, a clinical product, an infection-control product or an air-treatment device, and none is validated for clinical use.
Part one is the patient-facing non-clinical front. Entrance, lobby, reception, billing, waiting, attendant seating, a talking consultation room if it sits at the front, and the public circulation that joins them. Ordinary commercial interiors that happen to be inside a healthcare building. This is the whole of your opportunity and it is a genuine one: arrival, the wait, the discharge conversation and the paperwork all happen here, and these are the parts of the visit a patient or an escort will describe to somebody else afterwards.
Part two is the clinical zone. Pre-procedure, the procedure rooms, post-procedure and post-anaesthesia recovery, sterile storage, clinical and drug storage, clinical waste. Nothing, for the reasons this bank gives everywhere: not a lower setting, not a subtler register, nothing. Two ordinary and widely known facts sit behind that and neither is a claim about any product. Nausea after anaesthesia is ordinary, and recovery is where people experience it, which is reason enough for recovery to be fragrance-free; this page says nothing at all about fragrance helping, relieving, worsening or causing it, because no such claim exists to be made. And somebody waiting to be called is not in a state to be marketed at, which is an aesthetic and ethical point rather than a clinical one and is sufficient on its own.
Part three is the decontamination and scope-reprocessing area. A dedicated technical room with its own extraction, its own equipment, its own consumables and its own working atmosphere. It is not a patient room. It is not a public room. It is not a room where a brand belongs, and it gets nothing at any setting, in any register, for anybody - including the team who work in it. A fragrance product introduced into a technical room is an addition to an environment that other people design, manage and are accountable for, and that is not a decision a front-of-house budget gets to take.
Being precise about part three is worth doing because it protects you. Once the reprocessing area is named in the plan as a room that receives nothing, the plan can be shown to your clinical leads and your infection-control team as a document that already understands the building, rather than as a proposal that has to be corrected. In my experience that is the difference between a scenting plan that gets approved and one that gets refused on principle - and refusal on principle is a legitimate outcome that this page accepts in advance.
And the corridor or pass-through that connects part two and part three is not a fourth opportunity. It is a route planned by your facility for reasons that have nothing to do with atmosphere. Nothing goes in it.
A coverage figure - including SOSA's approximately 1000 cubic metres for the Vaayu at ₹11,999 - assumes one connected body of air. A machine cannot push scent through a closed door, and it has no particular ability to push it against a pressure difference either. So a building is scented volume by volume rather than building by building. In most commercial settings that is a limitation to work around. In yours it is the feature: it is precisely what allows a scented patient-facing front and a fragrance-free technical back to be an arrangement you can deliver rather than a claim you hope nobody tests.
Which makes the doors part of the specification rather than part of the building. A door that is shut is a boundary; a door that is propped open for convenience during a busy list is not, and for those minutes the two volumes are one. Door discipline between the front and the back is already an operational matter in your building for reasons that have nothing to do with fragrance, and it is your clinical and facilities leadership who own it. The scenting plan simply has to be honest that it depends on it.
Then the four mechanisms that defeat a door even when the door is shut, all of which I have found in real buildings and none of which has a fragrance answer. A door undercut, which is a deliberate gap and is there for airflow reasons that belong to your engineers. A shared return grille, where two rooms that look separate on the drawing hand their air to the same place. A corridor acting as a plenum between zones. And a machine sitting in a supply airstream, which takes whatever it produces and distributes it wherever that supply goes, which may be several rooms away from the one you were trying to scent.
The practical consequences are simple and they are all about placement. Put the unit inside the volume you intend to scent, facing into the room. Keep it away from the entrance draught, where it will be diluted and wasted. Keep it away from return grilles, because that is a direct route out of your room and into somewhere you did not choose. Keep it as far from the connecting door or corridor as the room allows. Never put it in the corridor. And never, under any circumstances, duct a scenting unit into air handling that serves a clinical zone, or into an extract system.
The last piece is a governance one and it is not optional: have your own facilities engineers or HVAC consultant confirm the placement before anything is drilled into a wall or plugged in permanently. They know what shares an air handler with what in your building. A page does not, a supplier does not, and neither should pretend to.
The reason is physical rather than moral. Fragrance adds scent. It does not remove odour. It does not neutralise, absorb, deodorise, sanitise, disinfect or purify anything, and no SOSA product makes any such claim. So a scent source placed in that corridor does not subtract the first smell; it adds a second one, and the two together produce a third impression that is nearly always worse than the original, because a pleasant character arriving on top of something is the exact combination human beings read as concealment. Everybody has met that third smell in a badly run building. Nobody has ever been reassured by it. And in a healthcare building the inference lands harder than anywhere else, because the visitor is already alert.
So the diagnostic list, in order, and notice that fragrance appears nowhere in it. Is the extraction serving that room actually running, and is it maintained? Is it doing what the building was designed for, which is moving air out rather than into your circulation? Is a door being propped open during busy periods? Is there a pressure relationship between the technical room and the corridor that means air moves in the wrong direction, which is a question an engineer answers with instruments rather than a manager answers by standing there? Is cleaning frequency matched to how the room is actually used? Is something being stored or transported in a way that puts it into the public route? Every one of those has an owner inside your organisation and an answer that fixes the thing at source.
And the rule that this bank will never bend, stated once more in the sharpest form available. Never reduce ventilation, close a vent, block a return, slow an extract fan or alter air handling so that a fragrance lasts longer. Not in a corridor, not in a lobby, not anywhere in a building like yours, for any commercial reason. A well-ventilated building is genuinely harder to scent, and this page states that honestly rather than pretending otherwise. You take the ventilation as given and solve the scenting question with sizing, placement and level. Ventilation wins. The engineers win. If that means your lobby holds less fragrance than a showroom of the same size, then it holds less fragrance, and that is the right trade.
One more version of the same principle, because it is the commonest form of the request I get from this speciality. Do not scent the connecting corridor "so that the transition is smoother". A corridor between a scented front and a technical back is the single worst place in the building for a machine: it is connected at both ends, it holds nobody for more than fifteen seconds, and anything you put there is being pushed at the two zones you are trying to keep separate.
What is left, once all of that is respected, is a perfectly good commercial proposition: a quiet, consistent register in the patient-facing rooms, at a level set for the person who has been sitting there longest, produced by a machine that is correctly placed and runs on a timer. That is worth having, and it is worth having honestly.
- List the patient-facing non-clinical rooms by name before you price a machine.
- Name reprocessing and the clinical rooms on the same drawing as receiving nothing.
- Send anything arriving from the technical side to your engineers, not to a supplier.
- Place the unit in the waiting room, away from doors, returns and the corridor.
Which register for the patient-facing rooms, and where the machine physically goes
With the boundary settled, the register question is quick and it is the least consequential decision on the page. There are seven in the water-based Hotel Collection, each one SOSA's own hotel-inspired interpretation, and SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand.
The filter for a building like yours is the one that governs this bank: clean and unsweet reads right. A heavy or sweet character in a building with procedure rooms does something particular and unhelpful, because sweetness arriving over a warm enclosed space is the shape people associate with covering something. In your speciality that association is worth avoiding with more care than usual, precisely because you never want a visitor's attention drawn toward the question of what is happening at the back of the building. A transparent register in the front rooms keeps attention on the desk, the seating and the information, which is where you want it.
White Tea Serenity - white tea, aloe, cedar - is clean, weightless and spa-like, and it is the register that most naturally reads as clean rather than as scented. It agrees with pale walls, glazing, daylight and a minimal fit-out, and it is very hard to over-notice.
Quiet Luxury - white tea, bergamot, cedar - is hushed and polished, with a little more lift at a threshold. It is the safest single decision in the collection for a very mixed public and the right answer if your front of house has darker joinery, a proper seating group and some hotel in the detailing.
Forest Suite - cedarwood, vetiver, green leaves - is grounding and green and the right one where the interior has stone, timber, concrete or real planting. It reads as structural rather than decorative, so a mixed public receives it as part of the building rather than as a fragrance somebody selected.
Tea Garden - jasmine, green tea, white tea - keeps its jasmine inside the tea and is the least risky floral in the collection, a step warmer than the white-tea pair and wanting a correspondingly lower setting. Warm Welcome - citrus, floral, sandalwood - is a genuine threshold register for a family-facing neighbourhood facility used at a fraction of a hotel level, and in a building with procedure rooms I would default to no.
Old-World Glamour - amber, violet, woods - is plush and evening-elegant and it is the wrong shape here, because plush in a clinical building is exactly the character that reads as covering. Lobby Bar - citrus, pepper, amber - is bold, playful and after-dark, and it has no home in a day-care hospital at any setting, since turning a theatrical register down produces a quiet theatrical register rather than an appropriate one.
Those seven are the water-based collection for the SOSA ultrasonics. The Vaayu and the ducted machines run four hotel-inspired waterless blends supplied with the machine as one of three bundle choices - two different fragrance systems rather than the same bottle in two sizes, which is worth saying on WhatsApp before you buy. And this page will not rank the seven on measured throw or longevity, because SOSA does not publish that comparison and because your volume, height, ventilation, door traffic and setting decide the outcome far more than the blend does.
| Scent | Why it suits the mood |
|---|---|
| White Tea Serenity · reception and waiting | White tea, aloe and cedar. Clean, weightless and hard to over-notice, and the register that most naturally reads as clean rather than as scented. In a building with procedure rooms at the back, a transparent character keeps attention on the desk and the seating rather than on the air. |
| Quiet Luxury · the safe default across the front | White tea, bergamot and cedar. Hushed, polished and unsweet, with enough lift to carry an arrival. One register at one level across entrance, reception, billing and the attendant seating is what makes the front of house read as a house character rather than as a room deodoriser. |
| Forest Suite · stone, timber or planted interiors | Cedarwood, vetiver and green leaves. Structural rather than decorative, so a mixed public receives it as part of the building. A good answer for a contemporary consultant-led fit-out, and an easy register to hold at a low level for hours at a time. |
| Nothing at all · reprocessing, the clinical zone and the connecting corridor | The decontamination and scope-reprocessing area, pre-procedure areas, procedure rooms, post-procedure and post-anaesthesia recovery, sterile and clinical storage, clinical waste, and the corridor or pass-through that joins the front to the back. Not a lower setting - nothing, and nothing for the staff working there either. Anything arriving from that direction is an extraction question for your engineers. |
The buying answer, sized to the rooms you can actually scent. State the ceiling assumption every time. A 400 sq ft reception at 11 ft is 4,400 cubic feet, and 4,400 / 35.3 is about 125 cubic metres. A 600 sq ft waiting area at 12 ft is 7,200 cubic feet, about 204 cubic metres. A 1,000 sq ft connected front of house at 11 ft is 11,000 cubic feet, about 312 cubic metres, and the same footprint at 14 ft is 14,000 cubic feet, about 397 cubic metres. A 1,500 sq ft public floor at 12 ft is 18,000 cubic feet, about 510 cubic metres. A double-height 600 sq ft entrance at 18 ft is 10,800 cubic feet, about 306 cubic metres, which is roughly double what the floor plan suggests.
For a single reception and waiting room, an ultrasonic is usually the whole purchase: the SOSA Boond at ₹899 for a small enclosed space or the SOSA Sukoon at ₹1,899 for a normal reception and waiting area, both running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999. The pack of seven 15ml bottles at ₹1,799 is how you audition registers in your own air rather than from a description, judged on day five rather than on the first afternoon. Where a large waiting area runs from the first list to the last, the SOSA Megh at ₹3,499 and its 6 litre tank means nobody is refilling mid-session.
For a larger connected front of house the waterless SOSA Vaayu at ₹11,999 is the commercial answer, rated for approximately 1000 cubic metres of connected air with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. In your building the waterless part is the argument that matters: cold-air nebulising of undiluted oil means no water, no humidity and no wet residue anywhere, which is why a facility with procedure rooms and a reprocessing area will consider it where it would not consider a machine with a tank. It takes a 400ml tank, mounts freestanding, on a wall or into HVAC, runs on DC 12V / 1A at 5W so it needs a live socket, and carries CE, RoHS and SGS. The Bluetooth app and timer let it run your list hours and stop, so nothing is running overnight into a closed building. It is an ambient fragrance product for public areas: not a medical device, not an infection-control or air-treatment device, not validated for clinical use, and it adds scent rather than removing odour. Its HVAC mounting option exists for commercial buildings generally, and in a building like yours it is never used to duct into air handling that serves a clinical zone or into an extract system - that is a line this page does not cross at any price.
Two systems, and they are not interchangeable. The ₹299 water-based bottle never goes into a Vaayu, nor into Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft or Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft, both of which run waterless nebulising oil and are ducted decisions taken with your own HVAC consultant. And if you want no plug, no noise and nothing to switch off at a small desk, the SOSA reed diffusers are their own registers from ₹749 lasting about 6 to 10 weeks - Morning Freshness at ₹749 is Malabar lemon, mint and eucalyptus, Mountain Breeze at ₹849 is Himalayan pine, sage and cedar, Garden Bloom at ₹799 is British rose and night-blooming jasmine, Evening Calm at ₹799 is Kashmir lavender and chamomile, and Fresh Brew at ₹849 is Coorg coffee and Kerala vanilla, which is the wrong shape for a healthcare desk for the sweetness reason above. A reed belongs on a front desk or a public shelf, never in a technical room and never in the connecting corridor.
Read next, inside this speciality group. If the question behind your question is really about long public dwell and washroom provision, that argument is in how a gastroenterology day-care centre should approach reception scenting. If your lists are short and high-volume and the lobby fills and empties in waves, the throughput argument is in how an ophthalmic day-surgery centre should approach ambient fragrance. And if you are being pushed toward a strongly branded front of house, the case for restraint is in how a cosmetic day-surgery centre should approach signature scent.
What SOSA does not publish and this page will not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time. Send your plan, your ceiling heights, your air-handling arrangement and your marked fragrance-free zone list on WhatsApp at +91 96192 18531. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition is a real SOSA service discussed there rather than priced on a page - though the cheaper honest answer comes first, which is that one of the seven registers held consistently already is a signature, because consistency makes a signature and uniqueness does not.
The SOSA scenting range
SOSA sells two different systems and one of the commonest mistakes is mixing them up. Size by the connected air volume of the room you are actually scenting - which in a day-care hospital is almost always the entrance, reception, billing and attendant lounge alone - floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres. A door that stays shut ends one volume and begins another.
| Machine | System | What it is for | Price |
|---|---|---|---|
| SOSA Boond | Ultrasonic · water-based | A small desk or corner unit for one enclosed room - runs the water-based Hotel Collection | ₹899 |
| SOSA Sukoon | Ultrasonic · water-based | A larger ultrasonic for a reception or consultation room - Hotel Collection from ₹299 | ₹1,899 |
| SOSA Megh | Ultrasonic · 6L tank | A large-tank ultrasonic for a bigger lounge that runs all day | ₹3,499 |
| SOSA Vaayu | Waterless cold-air nebulising | The commercial machine - approx 1000 m3 of connected air, Bluetooth app and timer, no water and no humidity | ₹11,999 |
| SOSA Aangan | HVAC nebulising | Ducted scenting for approximately 8,000 to 10,000 sq ft | ₹25,999 |
| SOSA Meenar | HVAC nebulising | Ducted scenting for approximately 12,000 to 18,000 sq ft | ₹38,500 |
Two systems, and they are not interchangeable. The ultrasonics - Boond, Sukoon and Megh - run the water-based Hotel Collection from ₹299. Vaayu and the HVAC machines run waterless nebulising oil; the ₹299 water-based bottle never goes into a Vaayu. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is independent and not affiliated with any hotel brand. A portion of every order supports girl-child education through Nanhi Kali.
- Vaayu ₹11,999 - waterless cold-air nebulising, approx 1000 m3 connected air, Bluetooth app and timer, 400ml tank, freestanding or wall / HVAC mount, DC 12V / 1A, 5W, mains powered, CE / RoHS / SGS.
- Aangan ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar ₹38,500 for approximately 12,000 to 18,000 sq ft - both ducted into HVAC.
- The ultrasonics - Boond ₹899, Sukoon ₹1,899, Megh ₹3,499 - run the water-based Hotel Collection from ₹299, with 100ml refills at ₹999.
- Not published, and therefore never stated on this page: consumption rate, refill frequency, monthly running cost, machine lifespan, installation lead time or any minimum order. Those go to WhatsApp +91 96192 18531.
Versailles
A day-care hospital is the most careful room I write about, and I want to be plain about why. Somebody walks in at seven in the morning to have a procedure. Their mother or their husband sits in your lounge for four hours with nothing to do but look at the walls and worry. And a few metres away, behind doors that should stay shut, there is a zone where none of this belongs at all.
So the answer here is not a stronger machine or a cleverer scent. It is a boundary. Entrance, reception, billing and the attendant lounge are the public half of your building and they are allowed to feel like somewhere that was thought about. Pre-op, procedure, recovery and everything clinical are the other half, and the honest answer for all of it is nothing. Not less. Nothing.
Two things I say to every facility that asks. Fragrance adds scent - it never subtracts one, so it cannot cover disinfectant, and a scent laid over disinfectant makes a third smell that reads worse than either. And the decision is not mine or yours alone: what is introduced into the air of a building with a surgical zone belongs to your clinical leads, your infection-control team and your engineers. I would rather lose the sale than have a page of mine used to argue past them.
Frequently asked questions
Facts verified September 2026: SOSA Vaayu ₹11,999 is a waterless cold-air nebulising diffuser rated for approximately 1000 m3 of connected air, with Bluetooth app and timer, a 400ml tank, freestanding or wall / HVAC mounting and a DC 12V / 1A, 5W mains supply. SOSA Aangan ₹25,999 covers approximately 8,000 to 10,000 sq ft and SOSA Meenar ₹38,500 approximately 12,000 to 18,000 sq ft, both ducted into HVAC. The ultrasonic machines - Boond ₹899, Sukoon ₹1,899 and Megh ₹3,499 - run the water-based Hotel Collection fragrance from ₹299, with 100ml refills at ₹999; that water-based bottle is not used in a Vaayu or an HVAC machine. Reed diffusers start at ₹749 and last roughly 6-10 weeks. A coverage rating assumes one connected body of air; scent does not travel through a closed door. Ambient scent research supports improved evaluations of a space and its service, longer dwell and stronger recall at moderate effect sizes - it does not support claims about bookings, fees or retention. Fragrance adds scent and does not remove, neutralise or purify odour, and no SOSA product makes any health, antibacterial or air-purifying claim. No SOSA product is a medical device, a clinical product, an infection-control product or an air-treatment device, and none is validated for use in a clinical environment. Nothing in this guide is clinical, infection-control or engineering advice: in a facility with a surgical or procedural zone, what may be introduced into the air is governed by the operator's own clinical leadership, infection-control policy and facilities engineering, and their decision overrides every recommendation here. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is independent and not affiliated with any hotel brand. Prices and availability are subject to change - see the live product pages.
