That is the method and it takes about twenty minutes. Every door that is normally shut ends one connected volume and begins another, because a coverage rating assumes one connected body of air and scent does not travel through a closed door. So an open-plan floor whose reception opens straight onto the workstations is one volume, however many people sit in it. The same floor with four doored meeting rooms, a doored pantry, two doored cabins and a doored client suite is nine volumes. Same square footage, same headcount, same air conditioning, completely different answer - and the difference is joinery, not fragrance.
Then the arithmetic, and this is where a Hinjawadi floor stops behaving like the small premises most scenting advice is written for. A floor of 12,000 sq ft at a 10 ft ceiling is 120,000 cubic feet, and 120,000 divided by 35.3 is about 3,400 cubic metres. A SOSA Vaayu at ₹11,999 is published for approximately 1000 cubic metres of connected air. You are not slightly over. You are more than three times over, and no setting on any machine closes that gap, because the gap is not a strength problem. It is a volume problem, and volume problems are solved by volumes and placement rather than by a bigger number.
And then the part that makes the whole question smaller than it looked. Once you have counted nine volumes, the perimeter decides which of them get anything, and most of them get nothing. Reception and the client-facing route are the company's rooms and the whole legitimate opportunity. The workstation floor, where people sit eight to ten hours a day for a year at a time, gets nothing - not a lower setting, nothing. The pantry gets nothing because food is the smell in a pantry. The meeting rooms your own staff use get nothing. So the real shape of the answer is not one machine versus nine. It is one or two units serving two volumes, and seven volumes deliberately left alone.
How do I actually count the volumes? Print the floor plan, walk it at a normal working hour, and mark every door. Then sort them into three piles: doors that are genuinely kept shut, doors that are propped open every afternoon, and doorways with no door at all. Only the first pile creates a new volume. A glass meeting room whose door is wedged open is part of the open plan. A pantry with a swing door that never latches is part of the open plan. Then measure ceiling heights, because they differ between a reception with a raised soffit and a workstation bay under a dropped ceiling, and the height is half the volume calculation.
My floor is bigger than one machine's rating. Do I buy a bigger machine? Usually not, because the question is wrong. A 12,000 sq ft floor at 10 ft is about 3,400 cubic metres against a Vaayu published for approximately 1000 m3 of connected air, and turning a unit up does not make it cover three times the air - it makes the twenty feet around it too strong while the far end stays unscented. The honest moves are to scent smaller volumes rather than the whole floor, to place units where the air is actually going, and to accept a gradient. The ducted machines - Aangan at ₹25,999 and Meenar at ₹38,500 - exist for whole-building work, but ducting into an air handler is a decision for whoever owns and maintains that system, never yours alone.
One: mark every door. Take the plan and walk the floor at about eleven in the morning, when it is genuinely in use. Put a mark on every door you pass and write next to it what you actually observe rather than what the plan intends. Shut. Propped open with a doorstop. Fitted with a closer that has failed and now stands half open. Glass partition with a permanent opening and no door at all. That last category is the one that surprises people: a great many meeting rooms on large open floors are enclosures rather than rooms, and an enclosure with a permanent opening is part of the floor's air, not a separate volume. Only a door that is genuinely kept shut divides anything.
Two: measure the ceiling, in each area separately. Reception often has a higher soffit than the workstation bays, and the workstation bays often sit under a dropped ceiling carrying services. Height is half the volume calculation and people guess it badly. Ten feet and twelve feet is a twenty per cent difference in cubic metres across the entire floor.
Three: do the arithmetic by hand for each volume you counted. Area multiplied by height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. On a representative 12,000 sq ft floor with a 10 ft ceiling, laid out with a 600 sq ft reception that is open to the floor, a 350 sq ft doored client suite, four doored meeting rooms of 200 sq ft each, a 300 sq ft doored pantry and two doored cabins of 150 sq ft each, the doored areas come to 2,350 sq ft and the open plan is the remaining 9,650 sq ft. So the reception and open plan together are 10,250 sq ft at 10 ft, which is 102,500 cubic feet, about 2,900 cubic metres in one connected body of air. The client suite is 3,500 cubic feet, about 99 cubic metres. Each meeting room is 2,000 cubic feet, about 57 cubic metres. The pantry is 3,000 cubic feet, about 85 cubic metres. Each cabin is 1,500 cubic feet, about 42 cubic metres. Nine volumes, and they differ from each other by a factor of nearly seventy.
Four: read what that actually says. The large connected volume is roughly three times the approximately 1000 cubic metres a Vaayu is published for, so one unit placed at reception will give you a real level near the unit and very little at the far end of the floor. That is not a fault and it is not something to correct with a bigger setting. It is a gradient, it is what physics does with a large connected volume, and on this particular floor the gradient is working in your favour, because the far end of the floor is where the workstations are and the workstations are exactly where you do not want scent. Meanwhile every doored volume is tiny - 42 to 99 cubic metres - which means a small room over-scents faster than anything else in this programme, and any unit put into one of them must run very low.
Five: apply the perimeter, which removes most of the shopping list. Of your nine volumes, two are the company's rooms: reception and the client suite. Those are where a visitor forms an impression of a business they do not work for, and they are the entire legitimate opportunity. The other seven are places your own people work, eat and meet, and they get nothing at all. So the answer to "zoning or one machine" is neither of the things you were choosing between: it is one unit for reception set low, optionally one for the client suite set lower still, and seven volumes deliberately and explicitly left alone.
Two boundaries before you spend anything. Your floor is on central air conditioning, and the SOSA ducted machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - do exist for exactly that kind of coverage. But in a leased floor inside a gated campus, the air handling is very often not yours. Never duct a scenting unit into an air handling system you do not own, control and maintain, and never proceed on a verbal nod from somebody who is not responsible for that plant. And I will never suggest you close a vent, shut down extraction or reduce air exchange so that a fragrance holds longer. A well-ventilated floor is genuinely harder to scent, and I would rather tell you that than sell you the opposite. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, print the floor plan and walk it with a pen. Not a site survey, not a vendor visit - you, the plan, and twenty minutes at eleven in the morning. Mark the doors, note which are honestly kept shut, measure two or three ceiling heights with a laser, and write the cubic metres on the plan next to each enclosed area. That single sheet answers more questions than any quotation you will be sent, and it is the document I would ask you for first.
The reason it matters so much on a floor like yours is scale. This is a gated corporate-campus belt rather than a high street: Hinjawadi is the Rajiv Gandhi Infotech Park, roughly 2,800 acres across three phases with more than 800 companies in it, and the buildings are sized for that. Almost every piece of scenting advice on the internet was written for a 400 sq ft shop, where the whole premises sits comfortably inside one machine's rating and the only real variable is the setting. Your floor inverts that. The machine is not your constraint and the setting is not your main lever either - the division of your floor into bodies of air is.
Be sceptical of your own nose while you do the walk, and even more sceptical of your team's. You and your facilities staff have been in that air since eight in the morning, and by mid-morning your noses have adapted and stopped reporting the room to you. That is ordinary physiology. It is also why, in a building where the morning commuter peak runs roughly eight to twelve and the evening one from about half past five to eight, the most useful observation of your reception comes from somebody who has just come off that commute and walked in from outside. Ask a courier. Ask a visitor at the end of their meeting. Do not ask the person who has sat at the front desk since the building opened.
And watch for the reflex that brings most facilities managers to this question in the first place: a complaint arrives, somebody says the fragrance is not reaching the far end, and the proposed fix is a bigger machine or a higher setting. On a 2,900 cubic metre connected volume, turning it up does not move the far end. It moves the twenty feet around the unit, where your receptionist sits all day.
One last framing, and it is the one that should govern the budget conversation. Dwell time sets the level and staff exposure caps it. A visitor is in your reception for four minutes. The person at the desk is in it for nine hours. Whatever number you were going to write down, the presence of that second person is an argument for a smaller one.
How to count the volumes on your own floor plan, and what the arithmetic then tells you
Three things decide whether a large Hinjawadi floor is a zoning problem or a single-machine problem, and none of them is headcount, budget or the specification of your air conditioning. The first is how the floor is divided - how many doors are genuinely kept shut, which is the only thing that turns one body of air into two. The second is the raw arithmetic of the volumes you end up with, which on a campus-scale floor produces one very large number and a handful of very small ones, and the two ends of that range take opposite advice. The third is the perimeter: who each volume belongs to, which is what decides whether a volume gets anything at all, and which removes most of the floor from the conversation entirely.
What does not decide it is the thing most quotations are built on, which is square feet. Square feet is an input, not an answer. Two floors of 12,000 sq ft, one open plan and one carved into twelve doored rooms, are completely different scenting problems, and a proposal written from an area figure alone cannot tell them apart.
It is worth being clear about what "central AC" changes and what it does not. A floor on central air handling has supply grilles pushing conditioned air in and returns pulling it out, and that moving air is the reason scent on a large floor behaves as a gradient rather than as a uniform level. It also means a unit placed directly in a supply airstream has its output picked up, carried away and thinned before it reaches anybody, while a unit in a dead corner behind a pillar never reaches the room at all. Placement beats output on almost every large floor I am asked about, and placement is free to change. What central AC does not do is make the floor one volume. Ducted air moves between rooms through the ductwork, but the scent you introduce into a room at floor level with a freestanding unit does not chase it around the building. The closed door still rules.
And keep Pune's two indoor seasons in view, because they change the setting on this floor twice a year. The monsoon room runs roughly June to October, with most rain June to September, July the wettest month and indoor humidity at its annual peak in July and August: closed up, slow, damp at the entrance where a few hundred people have arrived with wet shoes and umbrellas inside a long morning peak. The dry-heat room runs mid-March to mid-June, peaking in April and May with average highs around 37 to 38 degrees C, and the counter-intuitive verified part is that Pune's hottest months are its driest - the humidity trough sits in February to April. A floor running its cooling hard against dry April heat is moving and exchanging air faster, which is why the same setting that felt right in July seems to vanish by three in the afternoon in April. Two rooms, two written settings, one blend.
The three-pile sort. On the walk, every door goes into one of three piles. Pile one, doors that are honestly kept shut - a client suite with a closer that works, cabins whose occupants shut them, a pantry with a self-closing door that latches. These create real volumes. Pile two, doors that exist and are propped open all day with a doorstop, a bin or a fire extinguisher. These create no volume at all, and be honest about them, because a proposal built on a door that is never shut will fail in week one and the machine will be blamed. Pile three, doorways with no door. Part of the floor.
The half-open case, which is the one that causes arguments. A door fitted with a closer that has weakened and now rests six inches open is the worst of both worlds: it looks like a division on the plan and behaves like an opening in practice. So does a door with a large undercut at the bottom, which on many office floors is deliberate, because the gap under the door is how the room's air returns to the system. If a meeting room has no return grille of its own, that undercut is not a fault - it is the return path, and it means the room is exchanging air with the corridor continuously. Note it. It does not necessarily disqualify the room, but it explains why a level set on Monday is not there on Tuesday.
What to write down for each volume. Name it. Note the floor area from the plan. Measure its ceiling height rather than assuming it. Note whether it has a supply grille, a return grille or both, and where they are. Note whether it has a door and whether that door is genuinely shut. Note its normal occupancy and, crucially, how long a person is typically in it - four minutes at a reception desk waiting to be collected, an hour in a meeting room, nine hours at a workstation. That last column is the one that sets the level later, and it is the column that quotations never contain.
Then count. On the representative floor I described, the count is nine: one large connected volume of reception plus open plan, one client suite, four meeting rooms, one pantry, two cabins. The number itself is not the answer - it is the input to the perimeter question in factor three - but you cannot have that conversation until the count exists. Nobody scents a floor plan. They scent bodies of air, one at a time, and they decline most of them.
The large connected volume. Reception open to the floor plus the open plan, on our representative 12,000 sq ft floor, is 10,250 sq ft. At a 10 ft ceiling that is 102,500 cubic feet, and 102,500 divided by 35.3 is about 2,900 cubic metres. Raise the ceiling to 12 ft and the same area becomes 123,000 cubic feet, about 3,484 cubic metres - call it 3,500. Against a SOSA Vaayu published for approximately 1000 cubic metres of connected air, you are between two and a half and three and a half times over. This is worth sitting with, because it is the single most misunderstood number in commercial scenting. Being three times over a coverage figure does not mean you get a third of the intensity everywhere. It means you get a workable level in the region around the unit and progressively less further away, and a bigger setting extends the strong region rather than raising the weak one. The people who suffer from the correction are the ones nearest the machine.
The small volumes. A 200 sq ft meeting room at 10 ft is 2,000 cubic feet, about 57 cubic metres. A 150 sq ft cabin at the same height is 1,500 cubic feet, about 42 cubic metres. A 350 sq ft client suite is 3,500 cubic feet, about 99 cubic metres. Set 42 against approximately 1000 and you get the ratio that governs every small room in this bank: the machine is more than twenty times the volume's requirement, so the constraint in a small room is never the machine and always the setting, and a small enclosed room over-scents faster than anything else you own. This is why a unit that is perfectly judged in reception is unbearable in a cabin, and why moving one machine around a floor as a trial produces contradictory reports.
The spread, stated plainly. Your largest volume is about 2,900 cubic metres and your smallest is about 42. That is a factor of nearly seventy between two spaces on the same floor plan, served by the same air conditioning, occupied by the same company. Any single recommendation applied across all nine is wrong somewhere by a large margin. This is the entire case for zoning as a way of thinking - not as a shopping list of nine machines, but as an acknowledgement that one floor is not one problem.
What headcount does and does not tell you. Two hundred people in that 2,900 cubic metre volume is roughly 14.5 cubic metres of air per person, which is a density figure, not a coverage figure. Density changes how much the room smells of ordinary occupancy, how hard the air handling works, and how heavily the pantry and washrooms are used. It does not change the coverage arithmetic by a single cubic metre. If your headcount halved tomorrow and the walls stayed where they are, you would need the same machine at the same setting. That is the cleanest way to see why the question in the title has to be answered with volumes rather than with people.
And note what none of this arithmetic can do. It cannot tell you how much fragrance the machine will use, how often you will refill it, what it costs to run per month or how long it lasts, because SOSA does not publish consumption rate, refill frequency, monthly running cost or machine lifespan, and I am not going to invent them on a page. Those depend on your run hours, your connected volume and your setting. They go to WhatsApp at +91 96192 18531.
The principle. Scent belongs where a business is presenting itself to somebody who does not work there, and it does not belong where its own people sit for eight to ten hours a day. Reception, the visitor route and a client suite are the company's rooms: a visitor is in them briefly, by arrangement, as a guest, and they are the surfaces on which a business is legitimately allowed to have a character. A workstation bay is somebody's working environment for a year at a time. Nobody at a workstation chose the air. They accepted a job, not a fragrance. That asymmetry, and not any technical constraint, is the reason the answer is the perimeter.
Applying it to the nine. Reception: yes, low. The client suite: yes, lower still, for reasons of volume and dwell that I set out on the client-room page. The open plan: no - although, and this is the awkward part you have to face on an open floor, it is connected to reception and will therefore inherit a gradient from whatever reception has. The correct response to that is not a second machine somewhere else. It is a lower setting at reception, chosen so that the people sitting twenty feet away are not being scented all day as a side effect of a visitor's four-minute impression. Internal meeting rooms: no. They are used by your own staff far more than by visitors, and a doored room of 57 cubic metres is the easiest space in the building to overdo. The cabins: no, for the same reason, at 42 cubic metres each. The pantry: no, and not because of volume - because food is the smell in a pantry, and a fragrance in the same air as food and coffee gives you a third smell that most people like less than either. Fragrance adds scent; it never subtracts one.
The corollary about odour, which I have to be blunt about. If the reason you are reading this is that part of the floor smells of something - a closed, stale, end-of-day character, the pantry bin, a washroom lobby, carpet in a wet month - then no product I sell is the answer, and putting one there makes the diagnosis harder. No SOSA product treats, filters, dries, dehumidifies or purifies air. Not the Vaayu at ₹11,999, not an ultrasonic, not a ₹749 reed. The order never changes: source, then ventilation, then cleaning, then fragrance. On a large office floor the source is nearly always identifiable and nearly always somebody's responsibility already - waste handling, a drain trap that has dried out, an extract fan that has not been serviced, a carpet cleaning cadence set for a dry month and left unchanged into July.
And the staff arrangement, which is a standing policy rather than a favour. The people who work on a floor are the most exposed people in the building by a very large margin, and they are simultaneously the least reliable judges of the level because their noses adapt within an hour of arriving. So the level is capped by them, not by a visitor's impression, and anyone - a receptionist, a facilities executive, an employee who sits near a unit - can have a named unit switched off without asking a manager and without justifying it. Write it into the facilities SOP with the unit's name and location, so the person who needs it does not have to raise a ticket. A reported reaction is a recalibration signal, not a tolerance problem. I make no health or allergy claim in either direction, and nobody should ever be asked to discuss it in front of colleagues.
One last boundary that belongs specifically to a leased campus floor. If somebody proposes solving your 2,900 cubic metre problem by putting a scenting unit into the building's air handling, stop. Never duct into a system you do not own, control and maintain, and never on an informal approval. That conversation belongs to the building's engineering team and the landlord, and their decision overrides every recommendation on this page.
- Print the plan, walk it at 11 AM and mark every door as shut, propped open or absent.
- Measure ceiling heights per area, then write cubic metres on the plan for each volume.
- Apply the perimeter: reception and client suite only, everything else deliberately none.
- Set reception low for the nearest desk, write it down, and review it by season.
Which of those volumes get anything at all - and the honest answer is two of them
Now the register, which matters far less than the level and far less than the count you have just done. Two volumes are in scope on this floor: reception, and the doored client suite if you have one.
There are seven registers in the water-based Hotel Collection, each of them SOSA's own hotel-inspired interpretation, and SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand. For a corporate reception on a campus floor the steer is narrow and it is a context steer rather than a taste one: dry, clean, unsweet, low, and identical every single day. A reception that smells slightly different each week reads as somebody's hobby. A reception that smells the same every day reads as a building that is looked after, which is the only impression worth chasing here.
Quiet Luxury is white tea, bergamot and cedar - hushed and polished, and what I would run given one decision and no further information about your floor. White Tea Serenity is white tea, aloe and cedar, clean and weightless, and it is the one that most naturally reads as clean rather than as scented, which on a floor where two hundred people will walk past the unit twice a day is the safer end of the range. Forest Suite is cedarwood, vetiver and green leaves, the driest of the three and the one that reads most clearly as part of the building rather than as a decision somebody made.
The ones I would keep off an operational office floor. Lobby Bar is citrus, pepper and amber, bold and after-dark; turning a theatrical register down gives you a quiet theatrical register, not an appropriate one. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush accumulates in a connected volume in a way that dry does not. Warm Welcome is citrus, floral and sandalwood, a genuine hotel-threshold register that is lovely at a threshold and becomes the beginning of a sweetness problem in a room people walk through four times a day. Tea Garden is jasmine, green tea and white tea, the least insistent floral in the collection because the jasmine sits inside the tea rather than on top of it, and it is a reasonable choice for a client suite - but on a floor connected to workstations, a floral reads as a choice somebody made, and that is what your own people notice in month three.
I will not rank those seven against each other on measured throw or longevity. SOSA does not publish that comparison, and on your floor the variables that dominate - 2,900 cubic metres of connected air, the ceiling height, how hard the central system is working, how many people are in the room and the level you set - all belong to your building rather than to the blend. Same register at two written levels is always right; two registers on one connected floor is always wrong, because they meet somewhere in the middle of your open plan and make a third smell nobody chose.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · reception, and run low | White tea, bergamot and cedar. Hushed, polished and unsweet, and the default where a visitor is in the room for four minutes and a receptionist is in it for nine hours. Set for the second person. On an open floor the reception volume is about 2,900 m3 including the workstations it is connected to, so the honest expectation is a gradient rather than a level. |
| Forest Suite · a hard-surfaced corporate reception | Cedarwood, vetiver and green leaves. The driest register on the shortlist and the one received as structural rather than decorative, which suits a large lobby of stone, glass and planting where anything sweeter announces itself. Same register as the client suite, written at a different level, never a second register. |
| Tea Garden or Quiet Luxury · a doored client suite, lower still | Jasmine, green tea and white tea, or the same register as reception. A 350 sq ft suite at 10 ft is 3,500 cubic feet, about 99 m3 - roughly thirty times smaller than the connected floor and holding fewer people for far longer, so it takes a lower setting than reception and never a deeper one. |
| Nothing at all · open plan, meeting rooms, cabins, pantry | Seven of the nine volumes, and not a reduced setting - nothing. Workstations are where people spend eight to ten hours a day and did not choose the air. Internal meeting rooms at about 57 m3 and cabins at about 42 m3 over-scent faster than anything else on the floor. The pantry gets nothing because food is the smell in a pantry. |
So the buying answer, and it is smaller than the floor plan suggests. For a reception on a large connected floor the machine is the waterless SOSA Vaayu at ₹11,999: cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue. 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. 400ml tank, freestanding or wall and HVAC mount, DC 12V / 1A at 5W so it needs a live socket that facilities does not switch off at night, CE, RoHS and SGS. The Bluetooth app and timer is most of the value in a building like yours, because it lets one written setting run against your actual occupancy rather than being nudged by whoever is at the desk - and because Pune gives you two indoor seasons that need two different numbers.
For a single doored client suite of about 99 cubic metres, a second Vaayu is usually more machine than the room needs, and the honest smaller purchases are the ultrasonics: the SOSA Sukoon at ₹1,899 or the SOSA Boond at ₹899, both running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999 and 300ml also available. The pack of seven 15ml bottles at ₹1,799 is the sensible way to audition registers in your own air rather than from a description, judged on day five rather than on the first afternoon. Two systems, and they are not interchangeable: the ultrasonics are water-based cool-mist machines, while the Vaayu and the ducted units run waterless nebulising oil, and the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. The ducted machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - are the right technology for whole-floor coverage and the wrong conversation for a tenant who does not own the air handling.
If what you want in the client suite is no plug, no noise and nothing to schedule, the SOSA reed diffusers are their own registers rather than Hotel Collection ones: Mountain Breeze ₹849 is Himalayan pine, sage and cedar and the closest to a dry corporate direction; Morning Freshness ₹749 is Malabar lemon, mint and eucalyptus; Garden Bloom ₹799, Evening Calm ₹799 and Fresh Brew ₹849 complete the set. 130ml from ₹1,249, refills ₹2,399 and ₹3,499, lasting about 6 to 10 weeks. A reed is passive and local - it scents the few feet around it and will not fill a room, let alone a floor, which is a limitation and occasionally exactly the point.
To go deeper on what this page only touches: the reason seven of your nine volumes get nothing is set out properly in how a Hinjawadi office should handle fragrance when employees spend eight to ten hours inside, and the mechanism that makes the reception-and-not-the-floor answer real rather than a fudge is in whether IT workstation areas should stay fragrance-neutral while reception and client areas are scented. If the immediate problem is that a unit you already own is not performing, work through what a Hinjawadi facility manager should check before blaming the scent machine before you change anything.
What SOSA does not publish, and what this page will therefore not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time. Those depend on run hours, connected volume and setting, and they are yours rather than ours. Send the marked-up floor plan to WhatsApp at +91 96192 18531 instead. 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 - although 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 boutique means the connected retail floor plus any viewing room that has a door of its own - 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.

SOSA is a Pune business, so these are not pages I wrote from a desk somewhere else. I have stood in a Baner clinic in the second week of July and in a Kharadi tower in the middle of April, and the useful thing I can tell you is this: the locality on your signboard is not a technical variable. Nobody scents a postcode. What a locality name is actually shorthand for is a cluster of real things - how old the building is, whether the front is sealed glass or a door onto a pavement, what the air conditioning genuinely is, how many people come through, how long each of them stays, and what the room already smells of.
Which is why two businesses three doors apart can need completely different answers, and why the same business needs two different answers in July and in April. A Pune monsoon room and a Pune April room are not the same room. One is damp, closed up and slow; the other is dry, hot, and running its air conditioning so hard that whatever you put in the air is being moved and diluted faster than you think. That is a real difference and it belongs in the settings, not in the choice of blend.
The order never changes, though, and it is the least commercial thing I say: source, then ventilation, then cleaning, then fragrance. Fragrance adds a smell. It has never once removed one. If your unit smells of damp, or new paint, or last night's food, a machine will give you damp and fragrance - and most people find that worse than damp. Fix the thing making the smell, get air moving, clean what holds it, and then, if the room deserves it, give it a quiet character and hold it.
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 an air-treatment device, an air purifier, a dehumidifier, a humidity-control product or an odour-removal product, and none makes any health, allergy, air-quality or occupational claim. No claim is made here about any effect on a customer, a patient, a purchase, a footfall figure or a business result. Nothing in this guide is clinical, facilities, HVAC, food-safety or building advice: in a clinical space the treating clinician decides what may be in the air, in a food business the kitchen and the applicable food-safety rules decide, and in any building the people responsible for its air and its maintenance decide - and their decision overrides every recommendation here. Descriptions of Pune's seasons and localities are general and qualitative; every figure about a specific building must come from that building. 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.
