The reason splits cleanly into two halves. The first is about people: a visitor is a guest in your reception for four minutes by arrangement, while somebody at a workstation is a resident in that air for eight to ten hours a day, every working day, for a year or more, and they accepted a job rather than a fragrance. The second is about air, and it is the mechanism that decides whether the first half is even achievable. A coverage rating assumes one connected body of air, and a door that stays shut ends one volume and begins another. Scent does not travel through a closed door. That single sentence is what makes zoning real rather than a story you tell a client, and it is also what makes the tidy version of this answer unavailable to a great many large floors.
Because here is the part most proposals leave out. If your reception is a separate room with a door that is genuinely kept shut, you can scent it properly and the working floor is untouched, and the answer to the title is a clean yes with no complications. If your reception is a desk at the front of an open plan - which on campus-scale floors it very often is - then reception and the workstations are one body of air, the floor inherits whatever the lobby has, attenuating with distance but not stopping, and neutrality becomes a matter of degree rather than of walls.
The correct response to that is the counter-intuitive one and it is the most useful line on the page. It is not to add a second machine deeper into the floor so the level is more even. It is to set reception lower - low enough that the person sitting nearest to it, who will be there for nine hours, is not being scented all day as a side effect of a visitor's four-minute impression. On an open floor, the argument for neutral workstations is an argument for a quieter lobby, not for more equipment.
One correction of vocabulary before we go further, because it matters. Fragrance-neutral does not mean odour-free, and it cannot be produced by a fragrance product. Fragrance adds scent; it has never once removed one. No SOSA product treats, filters, dries, dehumidifies or purifies air. A neutral workstation floor still smells of something - people, coffee, warm electronics, carpet, whatever the building does in July. Neutral means you are not adding to it, and if what it smells of is unpleasant, the answer is source, then ventilation, then cleaning, and not a machine.
Our reception is part of the open plan. Can we still keep workstations neutral? Not completely, and it is better to say so than to pretend. A reception with no door is the same body of air as the floor behind it, so whatever you put in the lobby is in the workstation air too, weaker with distance but not absent. The right move is to set reception lower and to choose that level standing at the nearest desk rather than at the entrance - if the person sitting there can name the register, it is too high. Adding a second unit deeper into the floor to even out the gradient is the one move that actively defeats the purpose, because it scents the people you were protecting.
Does fragrance-neutral mean the workstation floor will smell of nothing? No. Fragrance-neutral means you are not adding a scent, not that the space has no smell. A working floor smells of people, coffee, warm equipment, carpet, cleaning products and whatever the season does to the building. Fragrance adds scent and does not remove, neutralise, absorb or purify odour, and no SOSA product treats, filters, dries or purifies air, so you cannot subtract with a diffuser. If the floor smells stale or of the pantry, that is a source, ventilation and cleaning problem with an owner who already exists in your organisation.
One: find out which building you are in. Stand at your reception desk and look behind you. If there is a door - a glass door, a pass door, an access-controlled leaf - that is normally shut between the lobby and the workstations, you are in the easy case. Your reception is its own volume, you can scent it properly and independently, and the working floor genuinely gets nothing. If instead the lobby simply becomes the floor, with an opening, a partial screen, a planter run or a change of flooring where the boundary would be, you are in the connected case. There is no third option and there is no partial credit: a screen is not a door, a planter is not a door, and a door wedged open with a bin is not a door either. The test is what the air can do, not what the plan shows.
Two: in the connected case, do the arithmetic so everybody stops arguing about it. A 600 sq ft reception opening onto 9,650 sq ft of open plan is 10,250 sq ft in one body of air. At a 10 ft ceiling that is 102,500 cubic feet, and 102,500 divided by 35.3 is about 2,900 cubic metres. A SOSA Vaayu at ₹11,999 is published for approximately 1000 cubic metres of connected air. So one unit cannot produce an even level across that volume, and what it produces instead is a gradient - a genuine level around the unit, less further out, effectively nothing at the far end. On a floor whose far end is workstations, that gradient is doing exactly what you want. The problem is never the far end. It is the near end, and specifically the two or three desks closest to the lobby.
Three: set the level from the nearest desk. This is the whole delivery method and it takes ten minutes. Put the unit in, run it, and then go and sit in the chair of the person who works closest to it. Not stand at the door. Not walk past. Sit there for five minutes, the way they do for nine hours. If you can name the register from that chair, the setting is too high and it comes down. If you can tell the air is pleasant but could not say what it is, you are close. If you can detect nothing at all from that chair, and a colleague who has just walked in from outside can tell that the lobby has a character, you have arrived at the best outcome available - and it is a very achievable one, because somebody arriving off a long Pune commute or out of April heat gets the biggest contrast anybody in the building will get all day.
Four: resist the fix that seems obvious. Within a month somebody will report that the fragrance does not reach the middle of the floor and will propose a second unit there. Say no, and say why: the middle of the floor is not a place you were ever trying to scent, and evening out the gradient means raising the exposure of the people who bear it most. If a second client-facing area genuinely exists deeper in the building, the correct response is to ask whether it can be given a door - because a door turns it into its own volume and lets it be set independently and low. Joinery solves zoning problems that machines cannot.
Five: be precise about what neutral means, in writing. Fragrance-neutral means nothing is being added. It does not mean the floor smells of nothing, and no fragrance product can make it so - fragrance adds scent and does not remove, neutralise, absorb, mask away, sanitise or purify odour, and no SOSA product treats, filters, dries, dehumidifies or purifies air. If the neutral floor smells stale, or of the pantry bin, or of a dried-out drain trap in a lightly used washroom lobby, that is a source, ventilation and cleaning problem, and on a building of this scale it already has an owner. Source, then ventilation, then cleaning, then fragrance - and never reduce ventilation, close a vent or shut extraction so a fragrance holds longer.
Six: write the standing switch-off before anything runs. Name each unit in the facilities SOP, record where it is, 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. The person who most needs that arrangement is usually the least likely to raise a ticket, which is why it has to be written rather than implied. A reported reaction is a recalibration signal, not a tolerance problem, and no health or allergy claim is made here in either direction. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, go and sit in the chair nearest your reception unit for five minutes. That is the entire quality control process for this decision and almost nobody does it, because the natural place to assess a lobby is standing in the lobby, which is where the visitor stands and not where the exposure is.
The second thing is to stop treating the closed door as a detail and start treating it as the specification. On a large floor, the question "which spaces can be scented independently" has exactly one answer and it is a list of rooms whose doors are genuinely kept shut. Everything else is one room, however it is drawn. I have seen proposals for campus floors that list eleven zones, and when you walk the floor, nine of those zones are open to each other and the whole document is describing something that cannot physically happen. A zone that is not bounded by a shut door is not a zone.
The third is to get the vocabulary right in your own internal communications, because "neutral" is the word that causes trouble. When facilities tells a floor that the workstation area will be kept fragrance-neutral, a proportion of people hear "odour-free" and then report that it is not working because the floor smells of lunch at half past one. Say what you mean: nothing is being added here. Smells that are already present are handled by the people who handle waste, cleaning and ventilation, and a diffuser is not one of those people.
And one observation about buildings at this scale, which is the reason the question gets asked in this corridor more than anywhere else. Hinjawadi is a gated corporate-campus belt rather than a high street - the Rajiv Gandhi Infotech Park, roughly 2,800 acres across three phases with more than 800 companies in it, and around 240,000 people commuting into it every day. The floors are large, the reception is often the only part of the tenancy a visitor sees, and the working population is big enough that any decision about the air is a decision about a couple of hundred people at once. That combination is exactly why the perimeter answer is right here and why it is worth writing down formally rather than leaving to whoever buys the machine.
Last framing, and it is the one to keep if you keep nothing else. Dwell time sets the level and staff exposure caps it. Everything on this page is one or the other of those two sentences applied to a floor plan.
The closed door, the connected volume, and what fragrance-neutral actually means
Three things decide whether a fragrance-neutral workstation floor is achievable, and only one of them is about fragrance. The first is the door - whether a boundary exists that air respects, because that is the only thing that separates one volume from another. The second is the arithmetic of whatever volume you end up with, which on a campus floor is large enough that a single unit produces a gradient rather than a level, and the shape of that gradient decides who is exposed to what. The third is what you mean by neutral, which needs settling in writing before anybody is disappointed by it.
What does not decide it is the machine, and I want to be clear about that because the question is usually put to a supplier. There is no product that scents a lobby and stops at an imaginary line four metres in. There is no setting that produces a level in one half of a connected room and nothing in the other. If the physical division is not there, no purchase creates it, and a supplier who says otherwise is describing a wish.
The arithmetic, done once by hand. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A reception of 600 sq ft at 10 ft is 6,000 cubic feet, about 170 cubic metres - comfortably inside the approximately 1000 cubic metres a Vaayu is published for, which is why a doored reception is easy and the only real risk is over-scenting it. The same reception opening onto 9,650 sq ft of workstations is 10,250 sq ft, which at 10 ft is 102,500 cubic feet, about 2,900 cubic metres, and at a 12 ft ceiling 123,000 cubic feet, about 3,500. The ratio between those two cases is roughly seventeen to one, produced entirely by the presence or absence of a door. No other single variable in commercial scenting moves the answer that far.
And hold both Pune seasons in view, because the setting you write is not a setting for the year. The monsoon room runs roughly June to October, most rain June to September, July wettest, indoor humidity at its annual peak in July and August - a closed-up floor with slower air and a damp entrance where a few hundred people have arrived with wet shoes across a long morning window. 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 verified counter-intuitive part is that Pune's hottest months are its driest, the humidity trough falling in February to April. A floor working its cooling hard against dry heat exchanges air faster, which is why the same number that felt right in July seems to have gone by three in the afternoon in April. Same register, two written settings, changed on purpose and recorded.
The things people mistake for boundaries. A glass partition with a permanent doorway: not a boundary. A run of tall planters: not a boundary. A change from carpet tile to stone at the lobby edge: not a boundary. A low screen behind the reception desk: not a boundary. A double-height void: not a boundary, and in fact usually the opposite, because it connects floors. A door with a failed closer resting half open: not a boundary. A door propped with a doorstop every afternoon because the pantry gets warm: not a boundary, and worse than useless in a proposal, because it will be listed as one and then fail in week one and the machine will get the blame. The only boundary is a door that is genuinely shut when the space is in use.
The honest grey case: door undercuts and transfer paths. Many office rooms have no return grille of their own and use the gap under the door as the return path back to the central system. That is a deliberate design feature rather than a fault, and it means the room is exchanging air with the corridor continuously even when the door is shut. It does not disqualify the room as a volume - the door is still doing most of the work - but it explains why a small doored room set on Monday can read differently on Wednesday, and it is another argument for setting such rooms low. If you find yourself wanting to block that gap to hold a level, stop. Never reduce ventilation, close a vent, block a transfer path or shut extraction so that a fragrance lasts longer, in any phrasing, ever. The building's air handling wins, and you compensate with placement, level and schedule.
What this means for the title question. If reception is doored, the split is trivially achievable: scent the lobby, leave the floor, done, and the only discipline required is not over-scenting a 170 cubic metre room with a machine rated for six times that. If reception is open to the floor, the split is directional rather than absolute, and the deliverable changes from "workstations get nothing" to "workstations get as close to nothing as a shared volume allows, and the lobby is set to make that true at the nearest desk". Both are honest. Only one of them is what most proposals describe, and it is not usually the one the building actually has.
And the practical corollary that saves money. Before you buy a second machine for a second client-facing area, ask whether that area can have a door fitted. A door costs less than a machine on most floors, it converts an aspiration into a volume, it lets that room be set independently and low, and it does several other things a scenting unit cannot - it isolates sound, it makes the room feel prepared, and it means a client conversation is not audible from the floor. Joinery is underrated as scenting equipment.
Why that is good news here. On an operational office floor, the region you want scented is small and near the entrance, and the region you want untouched is large and far from it. The gradient maps onto that almost perfectly. So the honest reading of "the fragrance does not reach the far end" is not that the installation has failed - it is that the installation is doing the one thing you asked for. I put it that bluntly because this is the single most common report a facilities manager receives in the first month, and the instinctive response to it is the wrong one.
The near-end problem, which is the real one. The desks closest to the lobby are inside the strong part of the gradient for eight to ten hours a day. Those two or three people carry the entire cost of whatever level you chose for the visitor, and they were not consulted. So the setting is not chosen at the entrance and it is not chosen by the person who buys the machine. It is chosen by sitting in the nearest chair and coming down until it is right from there. Everything else follows: if the visitor impression at that level is too faint for somebody's taste, the answer is not to raise it - it is to improve the parts of the arrival that are not fragrance, or to give reception a door.
Placement, which changes more than output does. A unit sitting in a supply airstream has its output picked up, carried away and thinned before it does anything in the room, so the lobby reads weak while the ductwork distributes it somewhere nobody chose. A unit in a dead corner behind a pillar or inside a joinery recess never reaches the room at all. A unit immediately beside an entrance is in the door's turbulence and loses much of its output every time the doors cycle - and on a campus building whose commuter peaks run roughly 08:00 to 12:00 and 17:30 to 20:00, those doors cycle in long, heavy waves rather than evenly through the day. The workable position is usually set back from the entrance, out of the direct line of a supply grille, not immediately under a return, at a height where nobody stands with their face beside it, on a socket the building does not switch off overnight. The Vaayu is DC 12V / 1A at 5W, mains powered, freestanding or wall and HVAC mount.
Schedule as a form of neutrality. The hours a unit runs are as much a part of the workstation floor's exposure as the level is. A timer that runs through the night is scenting an empty building and loading a volume that nobody is there to dilute, so the first people in receive the accumulation. A timer aligned to when the building is genuinely occupied does less and is received better - and in a corridor with long morning and evening peaks, "genuinely occupied" is a question for your own access-control data rather than for an assumption about how offices in the area operate. I am not going to tell you what hours your office keeps; your turnstile counts know and I do not. The published Bluetooth app and timer on the Vaayu is what turns that data into a setting.
What a neutral working floor actually smells of. Two hundred people. Coffee, at particular hours. Warm equipment and the dust that settles on it. Carpet and fabric that behave differently in a humid July than in a dry April. Cleaning products, which are a smell you have chosen even though nobody thinks of them that way. Food, if food is eaten at desks. Whatever is coming in from the lift lobby and whatever the central system is bringing round. That is the baseline, it is normal, and it is what "neutral" sits on top of.
The order, applied to an office. If the neutral floor reads stale, sour or closed at four in the afternoon, work it in this sequence and do not skip. Source: the pantry bin and its emptying cadence, a dried-out drain trap in a lightly used washroom or cleaner's sink, food left in desk drawers, a fridge nobody owns, a damp store cupboard, a mop and bucket living in a closed room, carpet in a wet month. Ventilation: whether extract fans in pantries and washrooms actually run and when they were last serviced, whether fresh-air intake is doing what it was designed to do, whether anybody has ever asked the building team. Cleaning: the cadence, and specifically whether it was set in a dry month and never revised for a monsoon one. Then fragrance, in the two rooms where it belongs. On a floor of this scale each of those items already has an owner in your organisation, and every one of them is cheaper than a machine.
What the honest ceiling is. Ambient scent research supports improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. That is the whole claim and I stop there. No productivity, focus, concentration, alertness, energy, creativity, mood, comfort or wellbeing claim, in any phrasing - and that temptation is at its strongest in exactly this kind of building, which is precisely why the refusal has to be explicit rather than implied. No claim that scent affects recruitment, retention, engagement, client wins or revenue. If a proposal in front of you contains any of those, the technical content is probably no more reliable than the claims.
And the switch, which is part of what neutral means in practice. Even with a perimeter-only policy, the desks nearest a lobby unit are in its gradient. So name every unit in the SOP, record its location, and write down that any member of staff may have it switched off or turned down immediately, without a manager's approval and without giving a reason. Repeat it at induction. Respond to a report by recalibrating rather than by investigating the person, never raise it with anybody in front of colleagues, and make no health or allergy claim in either direction. Staff are the most exposed people in the building and therefore the cap on the level, and a policy that depends on somebody being brave enough to complain is not a policy at all.
- Check for a real door between lobby and floor - a screen or planter is not one.
- Do the cubic metres for whichever volume you actually have, by hand, and write it down.
- Set the level sitting at the nearest desk, not standing at the entrance, then record it.
- Define neutral as nothing added, and give every unit a no-questions off switch.
One register, two written levels, and the test that tells you reception is too high
Now the register, and on this page there is one structural rule that outranks every question of taste: one register across the whole perimeter, written at different levels for different volumes. Never two registers on one floor. The reason is the mechanism this entire page is built on. Two registers on a connected floor meet somewhere in the open plan and make a third smell that nobody chose and nobody can describe, and two registers on a doored floor collide in the doorway every time somebody walks between the rooms. Same register, different written levels, is always the correct architecture.
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 large working floor the steer is narrow and it is a context steer rather than a taste one: dry, clean, unsweet, low, and identical every day.
White Tea Serenity is white tea, aloe and cedar - clean, weightless and spa-like, the register that reads most naturally as clean rather than as scented, and my default where the lobby is connected to the working floor, because the nearest desks will be living inside a diluted version of it. Quiet Luxury is white tea, bergamot and cedar, hushed and polished, with a little more presence at the same setting - which makes it the better choice where reception is a genuinely doored room and a poorer one 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 an installation, which is a real advantage in a lobby your own people cross four times a day.
The ones I would keep off an operational floor. Lobby Bar is citrus, pepper and amber, bold and after-dark; a register with personality is exactly what somebody passing it eight hundred times a year does not need. 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 true threshold register, lovely for the guest and the start of a sweetness problem for the 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 inside a doored client room and a poor one in a lobby that is part of the workstation floor, because a floral is heard 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 the variables that actually dominate on your floor - 170 cubic metres if the lobby is doored or about 2,900 if it is not, the ceiling height, how hard central cooling is working in a dry April, how many people are in the room, and the level you set - all belong to your building rather than to the blend.
| Scent | Why it suits the mood |
|---|---|
| White Tea Serenity · a lobby that is open to the floor | White tea, aloe and cedar. Clean, weightless and the least likely to be heard as a decision, which matters when the nearest desks live inside a diluted version of it for nine hours. Set the level sitting in that chair, not standing at the entrance, and expect a gradient across roughly 2,900 m3 rather than a level. |
| Quiet Luxury · a reception that is a genuinely doored room | White tea, bergamot and cedar. Hushed, polished and unsweet, with more presence for the same setting - which is only safe behind a door that is actually kept shut. A 600 sq ft lobby at 10 ft is 6,000 cubic feet, about 170 m3 against a machine published for approximately 1000, so the only real risk here is overdoing it. |
| Forest Suite · a doored client room or visitor corridor | Cedarwood, vetiver and green leaves. The driest register and the one read as structural rather than decorative. Use the same register as reception at a lower written level - a doored room of about 57 m3 is many times smaller than a lobby and holds people far longer, so it always goes down, never up. |
| Nothing at all · the workstation floor, cabins, meeting rooms, pantry | Not a reduced setting - nothing, and neutral means nothing is added rather than odour-free, because no fragrance product removes a smell. If the floor reads stale, that is source, ventilation and cleaning, in that order. The pantry gets nothing because food is the smell in a pantry, and a second smell there makes a third. |
So the buying answer. For a reception - doored or connected - the commercial machine is the waterless SOSA Vaayu at ₹11,999: cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue. 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, CE, RoHS and SGS. The Bluetooth app and timer is most of its value on a working floor, because it holds a written setting against the daily temptation to nudge, and it lets the schedule follow your own occupancy data across two Pune seasons.
If your reception is a small doored room of around 170 cubic metres, the Vaayu is more machine than the volume requires - which is an argument for running it low rather than against buying it, and also the point at which the ultrasonics become a genuine option. The SOSA Sukoon at ₹1,899 suits a reception and waiting area, the SOSA Boond at ₹899 a small enclosed room, and the SOSA Megh at ₹3,499 has a 6 litre tank for a larger lounge running all day. All three run 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 how to audition registers in your own air rather than from a description - judged on day five, not the first afternoon. Two systems, not interchangeable: the ultrasonics are water-based cool-mist machines 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 ducting is a decision for whoever owns and maintains the air handling - never a tenant's alone.
For a doored client room where you want 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, about 6 to 10 weeks. A reed is passive and local - it scents the few feet around it and will not fill a floor, which is a limitation and here is frequently the point.
To go deeper on what this page only touches: the method for counting how many volumes your floor actually has is in deciding between scent zoning and one machine on a 200-person Hinjawadi floor, the full case for leaving the working floor alone is in how a Hinjawadi office should handle fragrance when employees spend eight to ten hours inside, and if a unit you already own is being blamed for poor performance, work through what a Hinjawadi facility manager should check before blaming the scent machine first.
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 to WhatsApp at +91 96192 18531 instead, and mark on it which doors are genuinely kept shut. 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.
