I want to put the reason first rather than the method, because the reason is not technical. Nobody at a workstation chose the air. They accepted a job, not a fragrance, and unlike a hotel guest or a diner or a patient they cannot leave the room when they have had enough of it. They are in it tomorrow as well, and the day after, and in most cases for a year or more. A visitor in your reception is a guest for four minutes and consented to the visit. A person at a desk is a resident, and residents get a vote that guests do not.
Then the arithmetic, which is the part that decides it. A client comes in for a forty-five minute meeting, perhaps once a month: call it nine hours a year in your air. A person at a desk on a nine-hour day across twenty-two working days is about 198 hours a month, and across a year comfortably over two thousand hours. That is a ratio of more than two hundred to one, and it is not close. It is also, and I say this having written about hotels, restaurants, salons, clinics and showrooms, the longest continuous exposure of any space SOSA works on. A hotel guest stays two nights. A salon client sits for two hours. A physiotherapy patient lies in a room for an hour. An office worker is in one room for a year.
So the staff exposure is not a footnote at the bottom of the proposal. It is the cap on the level, and it is a cap that sits below every other consideration on the page, including the impression you want a visitor to have. And it comes with a standing arrangement that has to exist before the first machine is switched on: anyone - a receptionist, a facilities executive, somebody who sits near a unit - can have a named unit switched off, that day, without asking a manager and without explaining themselves. A report is a recalibration signal, not a tolerance problem.
Two things I will not claim, both of which are usually attached to this exact question. I will not tell you a fragrance does anything to a person - no productivity, focus, concentration, alertness, energy, mood or wellbeing claim, in any phrasing, because none of it is supportable and all of it is sold. And I will not tell you it affects recruitment, retention or any business result. The ceiling on what ambient scent research supports is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes - which is about how a room is received, and applies to a lobby rather than to a desk.
What about the workstations nearest reception on an open floor? They inherit whatever reception has, because a reception open to the floor is one connected body of air and scent does not stop at a change of carpet. That is the honest snag with an open plan and it has exactly one correct response: set reception lower, chosen for the person sitting twenty feet away rather than for the visitor standing at the desk. It is not an argument for adding a second machine deeper into the floor, which scents the people you were trying to protect. If the person at the nearest desk can name the register, reception is set too high, and that is the test to run rather than a debate to have.
Does scenting an office improve productivity or staff wellbeing? No, and SOSA makes no such claim in any phrasing. Nothing about productivity, focus, concentration, alertness, energy, mood, comfort or wellbeing, and nothing about recruitment, retention or business results. What ambient scent research supports is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. That is a statement about how a room is received by somebody passing through it, not about what happens to somebody working in it. Anyone claiming otherwise about a workplace is selling you something that has not been established.
One: define the perimeter before you choose anything. The perimeter is the set of spaces a visitor sees and your own people pass through rather than occupy. On a typical large floor that is the lift lobby if it is yours, the reception and its seating, the corridor a guest is walked along, and a doored client meeting room or suite. It is not the open plan, not the internal meeting rooms your teams use all day, not the cabins, not the pantry, not the washroom lobby. Draw it on the floor plan with a highlighter, and then be strict about it, because the perimeter has a strong tendency to creep once a machine is in the building and somebody says the third floor feels left out.
Two: do the exposure arithmetic and write the numbers in the proposal. Not because the numbers are surprising, but because they change the conversation from taste to policy. A visitor: forty-five minutes, monthly, about nine hours a year. A member of staff: nine hours a day, twenty-two days a month, about 198 hours a month and well over two thousand hours a year. Anybody arguing for a stronger setting is arguing to multiply the second figure, and the second figure is more than two hundred times the first. In my experience that single line ends the debate faster than any technical objection, because it reframes the level as something you are doing to your own colleagues rather than something you are doing for a client.
Three: accept the connected-volume consequence honestly. On an open floor, reception is not a separate room. A reception of 600 sq ft that opens onto 9,650 sq ft of workstations is one body of air of 10,250 sq ft, and at a 10 ft ceiling that is 102,500 cubic feet, about 2,900 cubic metres. A Vaayu is published for approximately 1000 cubic metres of connected air, so what you get is a gradient - a real level near the unit and progressively less further away. The gradient is your friend here, because the far end is workstations. But the near end is also workstations, the ones twenty feet from the desk, and those people are inside the strong region for nine hours. So the level is set by the nearest desk, not by the doorway. That is the single most practical sentence on this page.
Four: match the schedule to real occupancy, which in this corridor is not a tidy nine-to-six. Hinjawadi is the Rajiv Gandhi Infotech Park and roughly 240,000 people commute into it daily, with severe congestion running about 08:00 to 12:00 in the morning and about 17:30 to 20:00 in the evening, and PMPML running night bus routes. What that tells a facilities manager is not a fact about your office - it is a reason to go and look at your own access control data rather than assume. If your turnstile counts show arrivals spread across a long morning window and departures spread across a long evening one, a timer set to a notional nine-to-six is scenting an empty lobby at half past eight and an occupied one at half past seven. The Vaayu has a published Bluetooth app and timer, and this is what it is for. I am not going to tell you your office runs shifts or operates around the clock, because I have no way of knowing that and it is not a characteristic of the locality. Your own data knows.
Five: write the standing switch-off into the SOP on day one. Name the unit, record where it is, and state in writing that any member of staff may have it switched off or turned down, immediately, without a manager's approval and without giving a reason. Put the same line in the induction pack. The point of writing it down is that the person who most needs it is usually the person least willing to raise a ticket about it, and a policy that depends on somebody being brave is not a policy. I make no health or allergy claim in either direction, and nobody should ever be asked to discuss their own reaction in front of colleagues.
And the boundary that catches most office enquiries. If the reason you are asking is that the floor smells closed, stale or of yesterday's lunch by late afternoon, fragrance is the wrong tool and will make it worse. No SOSA product treats, filters, dries, dehumidifies or purifies air, and adding a register to a stale floor gives you a stale floor that also smells of cedar. Source, then ventilation, then cleaning, then fragrance - and on a large floor the source is nearly always somebody's existing responsibility. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, do the arithmetic on a whiteboard in front of whoever is asking for a stronger setting. Hours per year for a visitor, hours per year for the person at the nearest desk, and the ratio between them. It is not rhetoric, it is the actual shape of the decision, and it is the reason every honest answer in a workplace bends downward rather than upward.
The second thing worth doing is deciding who your test nose is, because it is not you and it is not your facilities team. Everybody who has been on the floor since eight in the morning has adapted; that is ordinary physiology and it is why buildings drift upward over time, one small nudge at a time, each one made by somebody who genuinely could not smell the previous setting. The report that counts comes from somebody who has been outside for ten minutes and has just walked in - a courier, a visitor arriving off the morning commute, a colleague coming back from another building. Ask them. Ask them the same question every time: can you smell anything, and if so, what would you call it. Write down what they say next to the date and the setting.
The third is to stop thinking of this as a fragrance decision at all and start thinking of it as an air policy for a building with two hundred residents. A fragrance policy in an office is closer to a lighting or temperature policy than to a purchasing decision: it affects everybody, it is felt continuously, it cannot be opted out of individually unless you make opting out explicit, and it therefore needs to be written, named, owned and reviewed. The parallel is exact, and it is why the switch-off arrangement is the most important paragraph in the SOP rather than a courtesy at the end of it.
And be ready for the awkward version of this question, which arrives sooner or later on every large floor: somebody senior liked the reception and would like the whole floor to smell like that. The answer is not a technical one about coverage, although the coverage answer is also no. The answer is that the reception belongs to the company and the workstation floor belongs to the people sitting in it for two thousand hours a year, and those are different kinds of room. It is a much easier conversation to have once before the machine arrives than repeatedly afterwards.
The exposure arithmetic, and why it points at the perimeter rather than at a setting
Three things decide how a large office floor should handle fragrance when its people are inside all day, and none of them is which register you like. The first is exposure: how many hours a year each kind of person spends in the air, which is the only number that matters and is almost never written down. The second is consent and control: whether the person in the air chose to be there, whether they can leave, and whether they can switch it off - which is why an office is ethically different from a hotel lobby even when the rooms look similar. The third is the architecture, because on an open floor the room you want to scent and the room you want to leave alone are frequently the same body of air, and pretending otherwise is how offices end up over-scented.
What does not decide it is the thing usually presented first, which is the impression a visitor forms. That impression is real, it is worth something, and it is comfortably achievable at a level far below what most people install. It simply does not get to outrank the residents.
The arithmetic behind the whole page, done once so you can check it. Twenty-two working days a month at nine hours each is 198 hours a month in the building; over twelve months that is 2,376 hours, and even on a conservative eight-hour day it is 2,112. A client attending one forty-five minute meeting a month is 9 hours a year. 2,376 divided by 9 is 264. So the person at the desk is in your air more than two hundred and sixty times as long as the client you were scenting the room for. Run the same comparison against the other spaces in this programme and the office stands alone: a hotel guest on a two-night stay, a restaurant diner at ninety minutes, a salon client at two hours, a physiotherapy patient at an hour. None of them is within two orders of magnitude of a desk.
And keep Pune's two indoor seasons in the frame, because a setting written once in November is wrong twice a year. The monsoon room runs roughly June to October, with most rain June to September, July the wettest and indoor humidity at its annual peak in July and August: a closed-up floor, slower-moving air, a damp entrance where several hundred people have arrived with wet shoes 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 - this is the verified and counter-intuitive part - Pune's hottest months are its driest, with the humidity trough in February to April. A floor working its cooling hard against dry April heat exchanges air faster, which is why the level that felt correct in July seems to have vanished by three in the afternoon in April. Two settings, written down, changed deliberately.
That asymmetry is the argument, and it does not need any health claim to do its work. I make no health or allergy claim in either direction and I am not going to imply one. The point is simpler and stronger: a continuous, unchosen, inescapable sensory addition to somebody's working environment is a different kind of decision from a four-minute impression in a lobby, and it should be made with a different standard of care. That standard is what produces the perimeter answer. Not caution, not hedging - a straightforward recognition of who is bearing the exposure.
The hours, stated so they can be quoted in a meeting. Nine hours a day, twenty-two days a month, is 198 hours a month and 2,376 hours a year. A monthly forty-five minute client meeting is 9 hours a year. The ratio is 264 to 1. If somebody proposes raising the setting by a quarter to improve the arrival impression, what they are actually proposing is to raise the exposure of two hundred residents by a quarter for two thousand hours in order to alter nine hours of guest experience. Put that way, the decision usually makes itself.
Why your own staff cannot be the judges of it. Olfactory adaptation is fast and complete: within roughly twenty minutes of continuous exposure most people stop registering a constant background scent altogether. So the people most exposed to a level are systematically the least able to report it, and the people best able to report it - visitors, couriers, somebody returning from another building - are in it least. That combination is exactly the mechanism by which office scenting drifts upward. Somebody cannot smell it, nudges it up, and everybody who walks in from outside receives a level nobody inside the building has consciously chosen. The correction is to fix the level by measurement and testimony rather than by feel, write it down, and only change it on purpose.
The switch, which is the practical expression of all of the above. Before the first unit runs, the SOP should name each unit, record its location, and state that any member of staff may have it switched off or turned down immediately, without a manager's approval and without giving a reason. Say it out loud in the induction. Say it again when a new unit is installed. And when somebody uses it, the response is to recalibrate rather than to investigate the person: a reported reaction is a signal about the setting, not a problem with the individual. Never raise it with somebody in front of colleagues, and never make the accommodation conditional on an explanation.
The mechanism. A coverage rating assumes one connected body of air, and a closed door is what ends one volume and begins another. A reception that opens onto the workstation floor has no door, therefore no boundary, therefore no second volume. Whatever you put into reception is in the workstation floor's air as well, attenuating with distance but not stopping at the carpet change. So the tidy proposition - scent reception, leave the floor neutral - is only fully available to offices whose reception is a separate doored room, and most large open-plan floors are not built that way.
The arithmetic of the combined volume. A 600 sq ft reception opening onto 9,650 sq ft of open plan is 10,250 sq ft of connected floor. At a 10 ft ceiling that is 102,500 cubic feet, which divided by 35.3 is about 2,900 cubic metres; at 12 ft it is 123,000 cubic feet, about 3,500. Against a Vaayu published for approximately 1000 cubic metres of connected air, one unit does not fill that. It produces a gradient: a genuine level in the region around the unit, less further out, effectively nothing at the far end. On this floor plan that gradient is a feature rather than a fault - the far workstations are unscented for free - but the near workstations are not, and that is the problem to solve.
The correct response, stated precisely. Set reception lower, and choose the level by standing at the nearest desk rather than at the entrance. Not at the door, not behind the counter, not in the middle of the lobby - at the chair of the person who sits closest to the unit and will be there for nine hours. If they can name the register, it is too high. If they can tell that the air is pleasant but not what it is, you are in the right place. If they cannot detect anything at all and a visitor arriving from outside can, that is the best outcome available and it is the one to aim for, because a person walking in from a Pune street in April or off a long morning commute gets the largest contrast anybody will get all day.
What not to do about the far end. Sooner or later somebody will observe that the fragrance does not reach the other side of the floor and propose a second unit there. On a floor whose occupants are the people you are trying to protect, that is the exact wrong move: it removes the one part of the gradient that was working correctly. If the far end genuinely needs to be addressed - because it contains a second client-facing area, say - then the right answer is to ask whether that area can be given a door, which turns it into its own volume and lets it be set independently at a low level. Joinery solves scenting problems that machines cannot.
Placement, which is free and beats output. A unit sitting in a supply airstream has its output picked up, carried away and thinned before it reaches the room, so the lobby reads weak while the ductwork distributes it somewhere you did not choose. A unit in a dead corner behind a pillar never reaches the room at all. A unit directly beside the entrance is in the doorway's turbulence and loses its output every time the doors cycle. The workable position on most receptions is set back from the entrance, out of the direct line of a supply grille, not immediately under a return, at a height where nobody is standing with their face next to it, on a socket that is not switched off by the building at night. The Vaayu is DC 12V / 1A at 5W and mains powered, so it needs a live socket, and it can be freestanding or wall mounted.
And the standing rule that applies to the whole building: never reduce ventilation, close a vent or shut down extraction so that a fragrance holds longer, and never duct a unit into an air handling system you do not own, control and maintain. A well-ventilated floor with two hundred people in it is genuinely harder to scent, and that is the correct trade to be making.
It cannot do anything to a person, and I will not say that it does. No productivity claim. No focus, concentration, alertness, energy, creativity, mood, comfort, calm or wellbeing claim, in any phrasing, however softly worded. This is the single most heavily marketed lie in workplace scenting and it is at its most tempting in exactly your building, where somebody can be persuaded that two hundred people will work differently if the air is treated. They will not, or at least nothing supportable says they will, and I am not prepared to earn ₹11,999 by implying it.
It cannot affect a business outcome, and that includes the HR ones. No claim that scent affects recruitment, retention, attrition, engagement, client wins, renewals or revenue. If a proposal in front of you contains a sentence about employer branding that implies a measurable outcome, treat the rest of the proposal with suspicion.
What it can honestly do, which is narrower and still worth something. Ambient scent research supports improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. That is the ceiling and it is where I stop. Read it carefully: it is about how a space is evaluated by somebody experiencing it, it is moderate rather than dramatic, and it is most relevant to a visitor forming an impression of a business they do not work for. Which is precisely why the perimeter is where the value sits and the workstation floor is not - the value was never on the workstation floor to begin with, so leaving it unscented costs nothing at all.
And it cannot fix an arrival that is not there. Most of what a visitor to a large campus building registers in their first two minutes is not fragrance. It is whether somebody looked up, whether their name was expected, how long they stood, how loud the floor behind reception is, whether the seating is clean, and whether the person collecting them seemed unhurried. Fragrance arrives late in that list. It is a finishing detail on a good arrival and it is entirely wasted on a poor one, and I would rather you spent the first ₹11,999 of your budget on whichever of those is currently missing.
- Draw the perimeter: reception, visitor route, doored client room. Nothing else.
- Set the level standing at the nearest desk, not at the door, then write the number down.
- Name every unit in the SOP with a no-questions switch-off anyone can use, same day.
- Match the timer to your own access data, and review the setting when the season turns.
The two rooms that are in scope, and the level that is capped by the people who live there
Assume the perimeter is drawn, the policy is written and the switch exists. Now the register, which matters far less than the level - and on this page the level is genuinely the whole subject.
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 reception on a floor where the same two hundred people walk past the unit twice a day, the steer is narrow and it is a context steer rather than a taste one: dry, clean, unsweet, very low, and identical every single day. The test is not whether a visitor admires it. The test is whether somebody who passes it four hundred times a year is still untroubled by it in month six.
White Tea Serenity is white tea, aloe and cedar - clean, weightless and spa-like, and the register that most naturally reads as clean rather than as scented. On a floor with a long-exposure population that reading is the entire brief, and it is what I would run given one decision and no further information. Quiet Luxury is white tea, bergamot and cedar, hushed and polished, with a little more presence at the same setting - correct for a reception that is genuinely separate from the working floor, and worth setting lower still where it is not. Forest Suite is cedarwood, vetiver and green leaves, the driest of the three and the one received as part of the building rather than as somebody's decision, which is exactly the quality you want in a room your own staff cross every day.
The ones I would keep off a floor like yours, and I would rather lose the order. Lobby Bar is citrus, pepper and amber, bold and after-dark - a register with personality, and personality is the thing that wears on somebody experiencing it for two thousand hours. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush accumulates in a connected volume in a way that dry simply does not. Warm Welcome is citrus, floral and sandalwood, a true hotel-threshold register that is lovely for the four-minute guest and the beginning of a sweetness problem for the nine-hour resident. Tea Garden is jasmine, green tea and white tea, the least insistent floral in the collection because the jasmine sits inside the tea; it is a fair choice for a genuinely doored client room, and on an open corporate floor a floral reads as a choice somebody made, which is what your colleagues 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 dominating variables - a connected volume of around 2,900 cubic metres, the ceiling height, how hard central cooling is working in an April, how many people are in the room, and the level you set - belong to your building rather than to the blend. And one architectural rule that applies here more than anywhere: one register across the whole perimeter, written at different levels per volume. Never two registers, because on an open floor they meet in the middle and make a third smell nobody chose.
| Scent | Why it suits the mood |
|---|---|
| White Tea Serenity · reception on an open floor | White tea, aloe and cedar. Clean, weightless and the register that reads as clean rather than as scented, which is the right brief where the same people pass it twice a day for a year. Set it standing at the nearest workstation, not at the entrance, and expect a gradient rather than a level across a connected volume of about 2,900 m3. |
| Quiet Luxury · a reception that is genuinely a separate doored room | White tea, bergamot and cedar. Hushed, polished and unsweet, with a little more presence for the same setting - which is only safe where a door actually separates the lobby from the working floor. Where it does not, use the same register at a lower written level rather than reaching for a quieter blend. |
| Forest Suite · a visitor corridor or client waiting bay | Cedarwood, vetiver and green leaves. The driest option and the one received as structural rather than decorative, so staff walking through it daily read it as the building rather than as an installation. Same register as reception, one level down, written on the same sheet so nobody nudges either of them. |
| Nothing at all · the workstation floor, cabins, meeting rooms, pantry | Not a reduced setting - nothing. This is where people spend eight to ten hours a day, more than two thousand hours a year, in air they did not choose and cannot leave. Internal meeting rooms at about 57 m3 over-scent fastest of anything you own, and a pantry gets nothing because food is the smell in a pantry. |
So the buying answer, and it is deliberately modest for a building this size. 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 and mains powered so it needs a live socket the building does not switch off overnight, CE, RoHS and SGS. The Bluetooth app and timer is most of the value here, for two reasons that are specific to a long-exposure workplace: it lets one written setting hold instead of being nudged by whoever is on the desk, and it lets the schedule follow your own access data rather than a notional nine-to-six in a corridor whose peaks run roughly 08:00 to 12:00 and 17:30 to 20:00.
For a single doored client room of about 57 to 99 cubic metres, a second Vaayu is more machine than the room needs. The honest smaller purchases are the ultrasonics: the SOSA Sukoon at ₹1,899 or the SOSA Boond at ₹899, running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999 and 300ml also available; the SOSA Megh at ₹3,499 has a 6 litre tank for a larger lounge that runs all day. The pack of seven 15ml bottles at ₹1,799 is the sensible way to audition registers in your own air, judged on day five rather than the first afternoon. Two systems, not interchangeable: the ultrasonics are water-based cool-mist machines, 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. 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 ducted, and on a leased campus floor that is a conversation for whoever owns the air handling.
If what you want at a client-room credenza 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, which on a long-exposure floor is a genuine advantage rather than a limitation.
To go deeper on what this page only touches: the method for working out how many volumes you are actually deciding about is in deciding between scent zoning and one machine on a 200-person Hinjawadi floor, the mechanism that makes a fragrance-neutral workstation floor real rather than aspirational is in whether IT workstation areas should stay fragrance-neutral while reception and client areas are scented, and the reason a doored client room takes a lower setting than your reception is worked through in keeping a Hinjawadi client meeting area feeling premium on a busy operational floor.
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 floor plan and your occupancy pattern 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 register 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.
- 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
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.
