Take them one at a time, because they fail differently. Dilution. A system that moves and exchanges a large quantity of air is continuously replacing the air in the room with air that has none of your fragrance in it. That is not a fault; it is the system doing its job. It does, however, mean the plain and slightly unwelcome truth of this page: a well-ventilated floor served by a large central system is genuinely harder to hold a level in than a small closed room, and there is no product that changes that. I would rather tell you so than sell you something that quietly fails.
Carriage. Air is moving in your ceiling and across your floor whether or not anybody can feel it, and a nebulised output does not travel on its own - it goes where the air already goes. Put a unit directly under or in front of a supply diffuser and its output is picked up at the diffuser's velocity, thrown across the plate and mixed into the whole supply volume. You have not scented the reception; you have contributed a trace to the entire floor. Put it next to a return grille and you have arranged for its output to be drawn straight out of the room. Put it in a dead corner behind a column, inside a cupboard or under a low shelf, and it never joins the room's circulation at all, so it is strong within a metre and absent everywhere else.
And direction. The one placement that works is deliberately unglamorous: in the room's general circulation, a few feet clear of a supply diffuser rather than under it, not adjacent to a return, at a height where its output joins the occupied part of the room rather than the ceiling void or the floor void - and within reach of a live socket, because the SOSA Vaayu at ₹11,999 is DC 12V / 1A, 5W and mains powered. On a large open plate that last constraint is not a detail. It frequently decides the answer before any theory does.
One thing about Kharadi specifically, said carefully. The district is a major IT centre in Pune's Eastern Metropolitan Corridor, anchored by the EON Free Zone and the World Trade Centre Pune; it was a village until around 2005 and developed rapidly through the 2010s and into the 2020s, so the stock is young, large-format and campus-scale rather than street-grain. What I will not do is tell you what the air handling in your building is. I have no verified basis for any claim about how buildings in this or any Pune locality are glazed, ventilated or cooled, and I am not going to invent one. If your floor is on a central system, that is something you know about your building, and everything below is written on your say-so. The people responsible for that system decide what happens to it, and their decision overrides every recommendation here.
Where should a diffuser physically go on a floor with central AC? In the room's general circulation and out of the jets. A few feet clear of a supply diffuser rather than directly under or in front of it. Not adjacent to a return grille, which draws its output straight out of the room. Not in a dead corner, behind a column, inside a cupboard or under a low shelf, where it never joins the room's air at all and reads strong within a metre and absent beyond it. At a height where the output enters the occupied part of the room. And within reach of a live socket: the Vaayu is DC 12V / 1A at 5W and mains powered, so power position is a real siting constraint on an open plate.
Should I duct a scenting machine into the building's air handling? Not into a system you do not control, and never on a fragrance supplier's say-so. SOSA does make 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 - but ducted scenting is a conversation with the engineers who own and maintain that plant, in a building where your organisation controls its own air handling. In a multi-tenant tower the air handling belongs to the building, and I will never suggest altering it, reducing air exchange or closing anything down so a fragrance lasts longer.
One: it is carrying your output somewhere you did not choose. This is by far the most common fixable failure and it is free to correct. Air in a conditioned floor is not still. It leaves supply diffusers with real velocity, travels, mixes, and returns through grilles somewhere else. A nebulised fragrance has no propulsion of its own worth speaking of; it joins whatever the air is already doing. So the position of the machine relative to the supply and the return is not a detail of installation. It is the single largest variable in whether the room reads as scented.
The three failure positions. In the supply airstream. Directly under or immediately in front of a diffuser, the output is picked up and thrown at the diffuser's own velocity, mixed into the full supply volume, and delivered everywhere at a concentration far below what you set it for. The subjective result is that the machine "does not work", and people respond by turning it up - which puts more product into the same dilution and changes very little. At a return. Set a unit within a metre or two of a return grille and you have plumbed it out of the room; whatever it produces goes into the return path before the room gets it. In a dead corner. Behind a column, inside a joinery recess, under a low counter, in a cupboard with the door mostly shut - here the opposite happens. The output never joins the room's circulation. It sits. The result is a machine that is noticeable to the point of unpleasantness if you stand beside it and entirely absent eight metres away, and a facilities team that concludes the coverage rating is a fiction.
The position that works is in the room's general circulation and out of the jets. A few feet clear of a supply diffuser rather than beneath it. Not adjacent to a return. At a height that puts the output into the occupied part of the room. Ideally on the path air naturally takes as it moves across the space rather than where it arrives with force. The Vaayu is published as freestanding - it lays flat - or wall and HVAC mountable, which gives you both a floor option and a height option. And it is DC 12V / 1A at 5W and mains powered, so it needs a live socket, which on an open plate with power in floor boxes under desks and in the walls of the core is frequently the binding constraint on where it can go at all. Work out the socket before you work out the theory.
Two: it is diluting, and that part is real. A system exchanging a large quantity of air is continuously replacing the air in your room with air that does not contain your fragrance. There is no placement that defeats that and no product that changes it. A big, well-ventilated floor is harder to hold a level in than a small closed room, full stop. The honest responses are to reduce the volume you are trying to hold - scent an arrival area rather than a plate - and to accept a gradient rather than chase uniformity. The dishonest response, which I will never make in any phrasing, is to reduce ventilation, close a vent, damp down extraction or ask anybody to lower an air change rate so the fragrance lasts longer. Ventilation wins. It should win.
Three: it changes with the season, so your floor is two different rooms. Pune's hot season runs mid-March to mid-June, peaks in April and May with average highs around 37 to 38 degrees C, and is - the verified and genuinely counter-intuitive part - the driest stretch of the year, with the humidity trough sitting in February to April. A building working hard against that heat is moving and exchanging air faster than the same building in a closed-up monsoon month, when most rain falls June to September, July is wettest, and indoor humidity is at its annual peak. So the complaint that arrives in my inbox every April - the fragrance vanishes by three in the afternoon - usually has nothing wrong behind it. The room is turning its air over faster, and by three your own nose has adapted anyway. Two written settings, changed at a scheduled review, recorded in the building file. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing before buying or moving anything, get a reflected ceiling plan for the area you want to scent - your facilities team or your fit-out drawings will have one - and mark the supply diffusers and the return grilles. Then walk the space with a strip of light tissue on a stick and hold it at head height under each one. You will find out in ten minutes, for free, where air arrives with force, where it leaves, and where it does nothing at all. That map is the actual specification for where the machine goes, and it beats every rule of thumb including mine.
The second thing is the socket survey, and it is duller and more decisive. The Vaayu is DC 12V / 1A at 5W and mains powered, and on a large open plate the available power is usually in floor boxes under desk clusters and in the walls of the core. Mark every live socket in and around the volume you care about. Overlay that on your air map. The intersection of "air does something useful here" and "there is power here" is a much shorter list than either on its own, and it is the real menu of options. I have seen more scenting schemes fail on power position than on coverage.
The third thing is to be honest about what you are trying to achieve, because uniformity across a large plate is not available and chasing it is expensive. Accept a gradient. A reception that reads clearly at the desk and fades as you walk into the floor is a normal, correct outcome and it is what the physics gives you. A floor that reads identically everywhere would require either a very large number of machines or an intervention in the air handling, and the first is a waste of money while the second is somebody else's building.
And watch for the diagnostic trap that costs facilities teams the most. When a room reads flat, there are four candidate explanations and only one of them is the machine: the unit is in the wrong place, the volume is far larger than one machine's published figure, the system is exchanging more air than you assumed, or your own nose has adapted after an hour in the room. Work through those four in that order before anybody orders a second unit, because three of the four are free and the fourth is not. And take your reading from somebody who has been outside for ten minutes rather than from yourself.
One last framing, and it is the one that makes this a Kharadi page rather than a generic mechanics page. This argument only matters at scale. In a three-hundred-square-foot room with a split unit, placement is a minor refinement. On a young, large-format, campus-scale floor plate with a central system moving a great deal of air, placement is most of the outcome and volume is the rest - and a bigger number on the app is neither.
What a central system does to a nebulised output, and the three places a unit must not go
Three things decide how a central system affects your fragrance, and they want to be understood separately because they have different fixes and different costs. Mixing and dilution is physics and it is not negotiable - the more air a system moves and exchanges, the lower the steady concentration anything will reach in that space. Placement is free and it is where almost all the recoverable performance lives. Volume is arithmetic, and it is the part that tells you honestly whether you are trying to do something that is possible at all.
What does not decide it is the setting on the app, except at the margins. A machine in the wrong position at a high setting is a machine in the wrong position. This is worth saying plainly because the commercial instinct in my industry is to sell you a second unit, and on a floor served by a central system the second unit frequently goes into the same bad position as the first.
Do the arithmetic by hand, because it is what turns this from an argument into a decision. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. Take a floor plate of 15,000 sq ft at a 10 ft finished ceiling: that is 150,000 cubic feet, which is 150,000 divided by 35.3, about 4,249 cubic metres of air. A more generous 5,000 sq ft area at a 12 ft ceiling - an atrium-side reception in a large-format building, say - is 60,000 cubic feet, about 1,700 cubic metres. A reception of 1,000 sq ft at a 12 ft ceiling is 12,000 cubic feet, about 340 cubic metres; the same reception at a 9 ft ceiling is 9,000 cubic feet, about 255 cubic metres. A boardroom of 400 sq ft at 10 ft is 4,000 cubic feet, about 113 cubic metres.
Now set those against the SOSA Vaayu at ₹11,999, published for approximately 1000 cubic metres of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. The boardroom and the reception sit comfortably inside that figure and should be run low. The 1,700 cubic metre atrium-side area is already past it. The 4,249 cubic metre plate is more than four times past it. Which is the finding of this page: on a large floor the answer is volumes and placement, not a bigger number. You choose which volumes are worth holding, you place well inside them, and you accept that the rest of the plate is not a target.
And note the ceiling height in those figures, because on large-format stock it does real work. A reception at 12 ft rather than 9 ft is a third more air in the same footprint. Height is the variable people forget when they size by square feet, and in young, large-format buildings it is frequently generous.
A central system does three things to that balance. It mixes, which is broadly helpful - it is the reason a well-placed unit can reach a room rather than sitting in a pool around itself. It moves, which is neutral in itself and becomes the placement question in the next section. And it exchanges, replacing conditioned air on some cycle, which reduces the steady concentration anything reaches. Exchange is the one that cannot be designed around, and it is the reason this page cannot promise you a uniformly scented floor.
I want to put the consequence in the plainest language I can. A well-ventilated space is genuinely harder to scent, and a large floor on a system that moves a lot of air is the hardest case in this bank. That is not a defect in the machine and it is not something a different machine solves. It is the cost of good ventilation, and good ventilation is worth far more than fragrance is.
Which brings me to the thing I will never say. Not once, not by implication, not in a sentence that could be read that way: do not reduce ventilation, close a vent, damp down extraction, shorten a fan schedule or ask anybody to lower an air change rate so that a fragrance holds longer. Ventilation wins every time. If a supplier ever suggests otherwise to you, that alone tells you what their advice is worth. The people responsible for your building's air handling decide what happens to it, and their decision overrides every recommendation on this page. Nothing here is facilities, HVAC, engineering or building advice.
The Pune seasonal layer on top of that. A building's cooling does not work equally hard all year, and Pune gives you an unusually clear contrast. The hot season runs mid-March to mid-June and peaks in April and May with average highs around 37 to 38 degrees C, and the genuinely counter-intuitive verified part is that Pune's hottest months are its driest - the humidity trough falls in February to April, the annual minimum sitting in exactly the hottest stretch. Pune sits at 570.62 metres on the western margin of the Deccan Plateau, on the leeward side of the Sahyadris, and it has a wide daily temperature swing: January runs an average high near 30 degrees C against an average low of 11.2 degrees C, and nights are roughly eight degrees cooler than Mumbai's. So a building here is working hard against dry afternoon heat in April, then dealing with a mild, damp, closed-up monsoon between roughly June and October when July is wettest and indoor humidity peaks in July and August, then handling genuinely cool nights in December and January.
Three different loads, three different amounts of air being moved, one machine at one setting. That is why a level that was correct in July reads as absent in April, and why the honest answer is two or three written settings across the year rather than a nudge whenever a room seems flat. Same register, different numbers, recorded in the file with the date they were changed.
Failure one: in the supply airstream. A unit sitting directly under or immediately in front of a supply diffuser has its output picked up at the diffuser's own velocity and carried away before it has done anything in the room you are standing in. It is then mixed into the full volume the system is supplying, which on a large plate is enormous. The subjective experience is precise and I get the email every week: "we can smell it if we stand next to the machine and nowhere else, and it seems to be all over the floor very faintly." That is the diagnosis, written by the person who thinks they are describing a fault. The fix is to move it a few feet, which costs nothing.
Failure two: at or near a return grille. Air is leaving the room there. A unit within a metre or two of a return is delivering its output into the return path rather than into the room, and no setting compensates for that. Returns are less obvious than supplies because nothing blows at you, which is exactly why this position gets chosen - it looks like a quiet corner and it is the opposite.
Failure three: the dead corner. Behind a column, inside a joinery recess, under a low counter, inside a cupboard with the door mostly shut, tucked behind a large planter. Here the output never joins the room's circulation at all. It is intense within a metre and absent at eight, and it is the position that produces complaints from the one person whose desk is nearest and disbelief from everybody else. It is also, in fairness, where machines get put when somebody has been told to hide them.
The position that works. In the room's general circulation, out of the jets. A few feet clear of a supply diffuser rather than under it. Not adjacent to a return. At a height that puts the output into the occupied part of the room rather than at ankle level or into the ceiling void. Preferably on a natural path that air takes across the space, so the room's own movement distributes it gently rather than firing it somewhere. And - a point that matters on a large open plate - not directly beside the main circulation route where people walk past it constantly, because the person who sits closest to it is the one who lives with your decision.
How to find all that for free. Get the reflected ceiling plan and mark supplies and returns. Then walk the space with a strip of light tissue at head height and watch it under each one. Ten minutes, no cost, and you will know more about your own floor than any specification will tell you.
Then the constraint that overrides the theory: power. The Vaayu is DC 12V / 1A, 5W and mains powered, so it needs a live socket. It is published as freestanding - it lays flat - or wall and HVAC mountable, which gives you a floor option and a height option, but neither removes the need for power. On an open plate the sockets are typically in floor boxes under desk clusters and in the walls of the core, and that list is short. Do the socket survey before the air survey if you like; you will end up overlaying them anyway, and the intersection is your real menu. In my experience more corporate scenting schemes fail on power position than on coverage.
And the thing not to do, stated once and clearly. Do not duct a scenting machine into a shared air handler you do not control. SOSA does make 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 - and ducted scenting is a real and sensible option where an organisation controls its own air handling for its own demise, with its own engineers in the conversation from the start. In a multi-tenant tower the plant belongs to the building. That conversation begins and ends with the people responsible for it, and their answer, whatever it is, is the answer.
Floor area multiplied by ceiling height gives cubic feet. Cubic feet divided by 35.3 gives cubic metres. On a young, large-format plate:
A floor of 15,000 sq ft at a 10 ft finished ceiling is 150,000 cubic feet, about 4,249 cubic metres.
A floor of 20,000 sq ft at 10 ft is 200,000 cubic feet, about 5,666 cubic metres.
An atrium-side reception of 5,000 sq ft at a 12 ft ceiling is 60,000 cubic feet, about 1,700 cubic metres.
A reception of 1,000 sq ft at 12 ft is 12,000 cubic feet, about 340 cubic metres; at 9 ft it is 9,000 cubic feet, about 255 cubic metres.
A boardroom of 400 sq ft at 10 ft is 4,000 cubic feet, about 113 cubic metres.
The Vaayu is published for approximately 1000 cubic metres of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. So the boardroom is about a ninth of that figure, the 1,000 sq ft reception at a 12 ft ceiling is about a third of it, and the plate is four to five times past it. Note what that does to the advice: in the small volumes the machine is not the constraint and the honest instruction is to run it low, while on the plate no setting is the answer at all.
Two more things the arithmetic makes obvious. Height matters more than people expect. The same 1,000 sq ft reception is 255 cubic metres at 9 ft and 340 at 12 - a third more air for the same carpet - and large-format buildings are frequently generous with height, particularly at the arrival level. Sizing by square feet alone will under-read a double-height space badly. And connection matters more than either. A coverage rating assumes one connected body of air. A door that stays shut ends one volume and begins another, and scent does not travel through it. So the number you should be computing is not your tenancy area; it is the area of the specific connected volume you intend to hold, with the doors that actually stay shut drawn as the boundary.
Which produces the recommendation this page exists to make. On a floor served by a central system, do not try to reach a number. Choose volumes. Take the arrival area and, if you want it, a doored client room. Compute each one honestly with its real ceiling height. Place well inside it, clear of the supply and the return, at a live socket. Run it low. Accept a gradient as you walk out of that volume into the plate, because a gradient is what the physics gives and chasing uniformity on a large floor is a way of spending money on disappointment.
And when it still reads flat, work the four candidates in order before anybody buys a second machine: is it in a bad position; is the volume far larger than one machine's published figure; is the system exchanging more air than you assumed; has your own nose adapted after an hour in the room? Three of those four cost nothing to check. Take the final reading from somebody who has been outside for ten minutes, ask a neutral question, and write the answer down with the time and the setting beside it.
One limit worth restating here rather than in a footnote, because a page about air handling is where a reader might start hoping otherwise. Fragrance adds scent. It does not remove, neutralise, absorb, filter, dry, dehumidify, sanitise or purify anything, and no SOSA product is an air-treatment device or an air purifier. Nothing on this page makes an air-quality claim in either direction, and no claim is made here about focus, productivity, alertness, mood or wellbeing.
- Mark the supply diffusers and return grilles on a reflected ceiling plan first.
- Walk it with a tissue at head height to find where air arrives, leaves and does nothing.
- Site the unit a few feet clear of a supply jet, away from returns, at a live socket.
- Compute the connected volume by hand, then shrink the target before raising any setting.
Choosing the volume first, then the register - and the honest ceiling on what placement can fix
With the placement and the volume settled, the register question is the short part - and on this page it comes with one addition, which is that a large, well-ventilated volume changes the level you will end up at rather than the blend you should choose.
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 arrival volume the steer is a context steer: dry, clean, unsweet, low, and identical every day. Quiet Luxury is white tea, bergamot and cedar, hushed and polished, and the default with one decision. White Tea Serenity is white tea, aloe and cedar, clean and weightless and spa-like, the one that reads as clean rather than as scented. Forest Suite is cedarwood, vetiver and green leaves, the driest of the three, and in a large-format interior of stone, timber and planting it is received as part of the building rather than as an addition to it. The four I would keep out of a corporate floor are Lobby Bar (citrus, pepper and amber, bold and after-dark), Old-World Glamour (amber, violet and woods, plush and evening-elegant), Warm Welcome (citrus, floral and sandalwood, a genuine hotel-threshold register but the start of the sweetness problem where several hundred people pass twice a day) and Tea Garden (jasmine, green tea and white tea, the least risky floral in the collection but still a floral, and a floral reads as a decision somebody made).
I will not rank those seven against each other on measured throw or longevity. SOSA does not publish that comparison, and on this page the reason is especially clear: the variables that dominate what anybody perceives on your floor - connected volume, ceiling height, how much air the system moves, where the machine physically sits, how many people are in the room and the level you set - all belong to your building rather than to the blend. A register does not have a range. A room has a range.
Now the level, calibrated for a diluted volume. Start lower than feels sensible - low enough that you cannot find it yourself after an hour in the room - and leave it untouched for a full week, because a level judged in the first afternoon is judged by the least reliable instrument available. Then take readings from people who have been outside for ten minutes: an arriving visitor, a courier, a colleague back from a client meeting. Neutral question, not a leading one. If two or three of them find something and call it pleasant and unobtrusive, you are right. If one names the fragrance unprompted, you are high. If nobody finds anything at all after a fortnight, you may go up one increment, once, and then leave it for another fortnight.
And write down two or three settings across the year rather than nudging. A building working hard against Pune's dry April heat is moving more air than the same building in a closed-up July, so the same number reads lighter in the hot season. Change it at a scheduled review, record what it went from and to, and keep the register the same. Consistency is the entire commercial value available here, and it is destroyed by a machine that anybody can adjust.
One standing arrangement, which belongs on every page in this bank. Anyone on the reception desk can switch a named unit off, immediately, on their own authority, without asking a manager. Your front-of-house team is in that air eight to ten hours a day and is the most exposed group in the building; a reported reaction is a recalibration signal, not a tolerance problem. I make no health or allergy claim in either direction.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · reception, sited clear of the supply diffuser | White tea, bergamot and cedar. Hushed and polished, and the default with one decision. Place a few feet clear of the nearest supply diffuser rather than beneath it, away from any return grille, at a live socket - the Vaayu is DC 12V / 1A, 5W and mains powered, so power position often decides this before anything else does. |
| White Tea Serenity · a client lounge on a natural air path | White tea, aloe and cedar. Clean, weightless and spa-like, and the register that reads as clean rather than as scented. A lounge where somebody sits twenty minutes runs lower than a reception somebody walks through, and a unit on the room's natural circulation path distributes gently instead of being fired across it. |
| Forest Suite · a double-height or large-format arrival area | Cedarwood, vetiver and green leaves. Dry and structural, and the one received as part of the building. Watch the height in the arithmetic: 1,000 sq ft at a 12 ft ceiling is about 340 cubic metres against 255 at 9 ft, so a generous arrival volume is a third more air for the same carpet. |
| Nothing at all · the open plate under full supply | Not a lower setting - nothing. A plate of 15,000 sq ft at a 10 ft ceiling is about 4,249 cubic metres against a machine published for approximately 1000 m3 of connected air, and it is also several hundred people's workplace for eight to ten hours a day. That is not a shortfall to solve with more output. |
So the buying answer, framed by placement and volume rather than by square feet. The SOSA Vaayu at ₹11,999 is the commercial machine: waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue - which in a Pune July when indoor humidity is at its annual peak is a plain design preference and never a claim to control humidity or treat air. Published for approximately 1000 cubic metres of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. Bluetooth app and timer, which is most of the value to a facilities function because it lets one written setting run to a schedule rather than being nudged. 400ml tank. Freestanding, laying flat, or wall and HVAC mountable - two mounting options that matter on this page, because height is part of placement. DC 12V / 1A at 5W and mains powered, so a live socket is a real siting constraint on an open plate.
Two systems, and they are not interchangeable. The ultrasonics - Boond at ₹899, Sukoon at ₹1,899 and Megh at ₹3,499 with a six-litre tank - are water-based cool-mist machines running the water-based Hotel Collection from ₹299, with 100ml refills at ₹999 and 300ml also available, and the pack of seven 15ml bottles at ₹1,799 is the sensible way to audition registers in your own air. For a single boardroom of about 113 cubic metres a Sukoon is frequently the whole purchase and ₹11,999 would be over-specifying. The Vaayu and the ducted machines run waterless nebulising oil, and the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine.
On 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 - the honest position for a tower reader is this. Ducted scenting is a genuine option where an organisation controls its own air handling for its own demise and its own engineers are in the conversation from the beginning. It is not something to be done to a shared system in a multi-tenant building, and no fragrance supplier including this one should be the person who authorises it. If your plant is the building's, the conversation starts with the building, their decision is final, and in the meantime a freestanding unit inside a volume you do control is the practical answer. Where no plug and nothing to schedule is the requirement, the SOSA reed diffusers from ₹749, lasting about 6 to 10 weeks, are passive and local - they scent the few feet around a desk and will not fill a floor, which on a plate like yours is a limitation and occasionally the point.
To go deeper on what this page only touches: if what you are actually seeing is a level that seems fine in the morning and gone after lunch, that is a daily curve and an adapted nose rather than an air handling problem, and it is set out in why a Kharadi office smells fresh at 9 AM and completely different after lunch. If the question is which volumes deserve to be chosen at all when several hundred people work on the floor, the perimeter argument is in how a premium office near EON IT Park should handle fragrance with hundreds of employees using the space daily. And the zoning mechanism, with the closed door doing the work, is in whether reception and workstation areas in a Kharadi corporate office should use different scent strategies.
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. Send your reflected ceiling plan, your ceiling height, the connected volume you actually want to hold and a photograph of where the nearest live socket is 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 |

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.

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.
