That is the answer. The reasoning is worth having properly, because the intuition most facilities teams start with runs the other way: the floor is emptier, so surely there is less to cover up and you can simply leave it as it is. Two things are wrong with that. The first is that fragrance was never covering anything up - fragrance adds scent and does not remove odour, and no SOSA product treats, filters, dries or purifies air. The second is that occupancy is not a neutral variable. People are the largest single influence on how a room behaves: they generate smell, they move air, they open doors, they bring food, and they absorb and disturb what is in the air simply by being in it. Take three hundred of them out of a floor and you have changed the room in a way that has nothing to do with how much there is to cover.
There is a second mechanism that only a facilities reader will appreciate, and it is the one that most often produces the complaint the weekend smells much stronger. A building's air handling frequently runs a different pattern outside core hours. I cannot tell you what your building does - that belongs to the people who maintain it and it is the first question to ask them rather than assume - but where a floor is served at a reduced rate at the weekend, the same output lands in air that is being turned over more slowly, arriving at the noses of the six people who happen to be in. So you have a smaller crowd, a slower room and an unchanged machine, which is precisely the combination that produces a level nobody chose.
And there is a third thing a weekend is for, which is the part of this page I care about most. A quiet floor is the best opportunity you get all week to do the things that actually fix smells - deep cleaning, airing the place out properly, dealing with the pantry, clearing waste that has been accumulating since Monday, servicing what needs servicing - because for once nobody is in the way. The order never changes: source, then ventilation, then cleaning, then fragrance. A Saturday is when the first three are cheapest to do, and the fragrance setting is the smallest decision you will make that day.
Two ceilings before we go on. Nothing here claims that scenting an office affects leasing, occupancy, retention, recruitment, client decisions or any business result, and nothing here claims that a scent does anything to the people in the building - no focus, concentration, alertness, productivity, mood or wellbeing claim, in any phrasing. What ambient scent research supports is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes.
Should it be higher at the weekend because there is nobody there? No, and the reasoning is worth being clear about. Fragrance was never covering anything up - it adds scent and does not remove odour, and no SOSA product treats, filters, dries or purifies air. Nor is there an arrival experience to build for on a quiet Saturday, because there are very few arrivals. Meanwhile the handful of people who are in - a weekend team, security, housekeeping - are the most exposed people per head in the building that day, which is an argument for less rather than more. Never use short high bursts to top a room up; that is the opposite of a calibrated setting.
What should I actually be doing on a quiet weekend? The things that fix smells, because nobody is in the way. Deep-clean the carpet tiles and upholstery that never get a proper turn on a Tuesday. Air the floor out properly. Attack the pantry - the sink, the drain, the fridge, the coffee machine tray, the microwave. Get waste out of the building rather than moved to a different corner of it. Book the air conditioning service that cannot happen mid-week. Then set the fragrance last and low, because that is where it belongs in the order: source, then ventilation, then cleaning, then fragrance. A weekend spent on the first three is worth more than any change to the fourth.
Now why the weekend room is genuinely different, in the order the effects actually matter. First, occupancy. A large-format Kharadi floor on a Tuesday is a room with several hundred people in it, and people are not passive: every one of them is a source, a mover of air and an opener of doors. They bring lunch onto the floor, they use the pantry, they generate waste, they walk through the lobby with wet shoes in July, and collectively they stir the air in a way no diffuser does. Take ninety per cent of them out and you have removed most of the loading and most of the mixing at the same time. The room is cleaner and slower, simultaneously.
Second, the building's own pattern. This is the mechanism that explains the complaint I get most often about weekends, which is that the floor smells noticeably stronger on a Saturday than it ever does on a Tuesday, with nothing changed. Where a building runs its air handling at a reduced rate outside core hours - and many do, for entirely sensible reasons that are nothing to do with fragrance - the air on the floor is being exchanged more slowly. The machine is putting out the same amount into a room that is clearing it more slowly, and the handful of people present receive the result. I want to be precise about my standing here: I do not know what your building does at the weekend, that information belongs to your facilities team, and asking them is the correct first step. What I will never do is suggest that you or anybody else reduce ventilation, close a vent or change a fan schedule so that a fragrance lasts longer. Ventilation wins. If your floor is well ventilated at the weekend, that is a good thing and you compensate with the setting rather than the air.
Third, the arrival experience, which is the thing fragrance in a reception is genuinely for. On a weekday your arrival volume works hard: visitors, candidates, couriers, client meetings, people coming back from outside. On a quiet Saturday there may be six arrivals all day and four of them are staff who were here yesterday. The case for a considered reception level is substantially weaker, and the case for exposing a small weekend team to a full weekday level for nine hours is weaker still. The few people who are in at the weekend are the most exposed people per head in the building that day, and that is not a rhetorical point: a weekday level is calibrated against a room full of people arriving and leaving, and on a Saturday the same level is delivered to a security guard, a housekeeping team and three engineers who cannot go anywhere else.
And here is what I would rather you spent the weekend on. The genuinely useful weekend activity is not the fragrance setting; it is everything that comes before fragrance in the order. Deep-clean the carpet tiles and the upholstered seating that can never get a proper turn on a Tuesday afternoon. Open the floor up and air it out properly while there is nobody to inconvenience. Take the pantry apart: the sink and its drain, the fridge and whatever is at the back of it, the coffee machine drip tray, the microwave, the bin and the space behind the bin. Get waste out of the building rather than consolidated into a different corner of it. Book the air conditioning service that is impossible to schedule mid-week. Every one of those does more for how the floor reads on Monday morning than any change to a diffuser, and all of them are cheaper. Source, then ventilation, then cleaning, then fragrance - a quiet weekend is the one time of the week when the first three are easy. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this month, come in on a Saturday morning and stand in your reception for two minutes before you do anything else, having arrived from outside. That is the only unadapted judgement anybody in your organisation will make all week. Then walk the floor the way a visitor would - lift lobby, reception, the route to the meeting rooms, the pantry, the washroom corridor - and note where the room is different from how it is on a Tuesday. It will be different in more places than you expect, and almost none of the differences will be about the diffuser.
Then write the three settings down. Not in somebody's head, not in a WhatsApp message to the vendor: in the facilities document, with a date, with the name of the person authorised to change them, and with a line saying they are reviewed at the season change. A written setting is a setting you can defend when somebody says it feels strong, and it is the only thing that stops the slow upward drift that happens in every building where the level is adjusted by whoever is standing nearest.
Be honest about whose nose you are trusting. Your weekday team have adapted by mid-morning every single day and genuinely cannot report the level to you. Your weekend team have usually just arrived and can. Ask them, and make it easy to answer - a named person, a standing question, no implication that reporting it is a complaint. Anyone on the desk should be able to switch a named unit off without asking a manager, at the weekend more than any other time, because the weekend skeleton crew has the highest per-head exposure in the building and the fewest colleagues to compare notes with. That is a standing arrangement rather than a favour, and a reported reaction is a recalibration signal rather than a tolerance problem. I make no health or allergy claim in either direction.
Two things not to do, both of which come up in every weekend conversation. Do not run short high bursts to top the room up before an occasional Saturday visitor arrives - a burst is not a calibrated level, it is a spike delivered to whoever happens to be standing there, and it teaches a building to expect the wrong thing. And do not leave a weekday setting running through a closed Sunday on the theory that the floor will be ready on Monday. A closed floor with reduced air movement accumulating for thirty hours is not ready. It is loaded, and the first people through the door on Monday receive all of it.
One last framing. The question is not how strong the weekend should be. It is who is actually in the building and for how long. Answer that honestly and the setting writes itself.
Why a Saturday floor is a different room, and the three settings to write down
Three things decide the weekend answer, and the fragrance machine is the least interesting of them. The first is occupancy, which is the single biggest determinant of how a room behaves. The second is what the building itself does outside core hours, which is not yours to change but is very much worth knowing. The third is what a quiet floor is actually for, which is the work that fixes smells rather than the work that adds one.
What does not decide it is the amount there is to cover, because covering is not a thing that happens. Fragrance adds scent; it does not remove, neutralise, absorb, mask away or purify odour, and no SOSA product treats, filters, dries or purifies air. If your floor smells of last night's food on a Saturday morning, a fragrance setting will give you last night's food and a register, which is a third smell most people like less than the first. The answer to that is the pantry, the bin and the air, in that order.
Do the arithmetic once, because it tells you why a large floor is a volumes-and-placement problem rather than a strength problem. A 10,000 sq ft floor plate at a 12 ft ceiling is 10,000 multiplied by 12, which is 120,000 cubic feet, and 120,000 divided by 35.3 is about 3,400 cubic metres. A 5,000 sq ft floor at 12 ft is 60,000 cubic feet, about 1,700 cubic metres. A 2,000 sq ft reception and lounge at 12 ft is 24,000 cubic feet, about 680 cubic metres. And a 200 sq ft meeting room at 10 ft is 2,000 cubic feet, about 57 cubic metres. Against a SOSA Vaayu published for approximately 1000 cubic metres of connected air, a whole large floor plate is simply not a one-machine proposition, and the honest answer on a campus-scale Kharadi floor is volumes and placement rather than a bigger number. It also means the weekend decision is not one decision: it is a decision per volume, and some of those volumes should be off entirely.
And keep the two Pune seasons in the frame, because they intersect with the weekend question directly. In the monsoon, roughly June to October with July wettest and indoor humidity at its annual peak in July and August, a closed weekend floor is the classic setup for a Monday-morning complaint: damp soft furnishings, still air, and thirty hours of nothing moving. That is a ventilation and cleaning answer, not a fragrance answer, and it is the strongest argument in this bank for using a Saturday to air a floor out. From mid-March to mid-June the city is hot and genuinely dry, with the humidity trough in February to April and average highs near 37.9 degrees C in April, so a weekday floor is having its air worked hard - which is why the same setting reads quite differently in April and in July, and why two seasonal settings sit underneath the three occupancy settings rather than replacing them.
Now take ninety per cent of them away. What you have left is a floor with far less loading, far less mixing, and far fewer doors opening. It is cleaner and it is stiller, and those two effects push in opposite directions for your nose: less to notice, but what there is sits where it was put. That is why a weekend floor so often reads as more fragranced rather than less, even though nothing about the machine has changed. The same output is now the most active thing happening in the room.
The second occupancy effect is the arrival curve, and it is the one that decides whether you scent at all. An arrival volume earns its setting from arrivals. On a weekday your reception handles visitors, candidates, couriers, client meetings and several hundred people coming back from lunch - the volume is doing real work and the level is being received by people who have come in from outside, which is the largest contrast anybody gets. On a Saturday with a skeleton team and two deliveries, the volume is doing almost no work, and the level is being received almost entirely by people who are stuck with it for nine hours. The purpose has changed, so the setting should change with it.
The third is the pantry, which deserves its own sentence on a weekend page. On a busy weekday the pantry is the most loaded volume on the floor and also the most frequently disturbed - it is being used, cleared, wiped and ventilated by sheer traffic. On a quiet Saturday it is loaded from Friday and disturbed by nobody, which is why a Saturday morning pantry is often the worst-smelling room in a building that is otherwise at its best. That is a source problem with a source answer: the sink and its drain, the fridge, the coffee machine tray, the microwave, the bin and the space behind the bin, and waste that leaves the building rather than moving to a different corner of it. Never scent a pantry to deal with it. You will get food and a register, which is the third smell nobody wants.
And the Kharadi-specific version of all this. This is a young, large-format, campus-scale office district - a village until around 2005, developed exponentially through the 2010s - which means the occupancy swing between a weekday and a weekend is proportionally enormous. A small high-street unit goes from six people to one. A large corridor floor plate can go from several hundred to a dozen. The bigger the weekday crowd, the bigger the difference between your two rooms, and the less defensible it is to run one setting across both.
I do not know what your building does, and neither does any fragrance supplier. That information sits with your facilities team or your landlord's operations team, and asking them is the first move rather than the last. The questions worth asking are precise and answerable: does the air handling serving our floor run a different schedule at weekends, is there a reduced fresh-air rate outside core hours, and is there an out-of-hours request process if a floor is being used. You are not asking for a change. You are asking so that you stop attributing to your diffuser something that belongs to the building.
The line I will not cross, stated once and meant. Nothing in SOSA's commercial advice will ever suggest reducing ventilation, closing a vent, blocking a grille, restricting extraction or changing a fan schedule so that a fragrance lasts longer or reads stronger. Not on a weekend, not in a monsoon month, not anywhere. A well-ventilated floor is genuinely harder to scent, and that is a fact I would rather state than work around. The compensations available to you are placement, level and schedule, all three of which are yours and none of which touches the air.
There is also a weekend version of the closed-door argument. On a weekday your meeting rooms cycle: doors open, people come and go, rooms get used and reset. On a weekend they sit shut for forty-eight hours. If you have units in doored rooms, a closed 57 cubic metre volume with nothing moving through it accumulates in a way an open floor simply does not, and the first meeting on Monday morning walks into all of it. That is the single strongest argument for a scheduled off period in doored rooms rather than a reduced one. A coverage rating assumes one connected body of air, and over a weekend those small volumes are as disconnected as they ever get.
And the monsoon version, which is the one that generates Monday complaints. A Kharadi floor closed from Friday evening to Monday morning in the second week of July is a closed, still, humid volume for something over sixty hours, with carpet tiles and upholstered seating holding moisture and nothing moving. If it reads heavy on Monday, that is damp and stillness, and the response is airing and cleaning, not a higher setting. Adding fragrance to that room gives you damp and fragrance, which most people find worse than the damp on its own. This is the point in the week where the instinct to add is most strongly wrong.
Source. The pantry, taken apart properly rather than wiped: the sink and its drain, the fridge and the back of the fridge, the coffee machine drip tray and its waste container, the microwave, the bin and the floor behind the bin, and the cupboard where somebody's forgotten container has been since Wednesday. Waste that leaves the building rather than being consolidated somewhere else in it. Any store cupboard that has quietly become a place where damp things live - and in Pune between June and October, when indoor humidity is at its annual peak in July and August and nothing air-dries, that cupboard exists in almost every building. Cleaning equipment, especially a mop head living damp in a bucket, which is one of the commonest unnoticed contributors to a closed-smelling premises anywhere in this bank.
Ventilation. Open the floor up. This is the one activity that is genuinely impossible on a weekday in an occupied office and genuinely easy on a Saturday. Where your building allows it and the people responsible agree, a properly aired floor on a Saturday morning changes Monday more than anything else on this list. Where mechanical extract exists that nobody has ever had looked at, a quiet day is when it can be looked at.
Cleaning. The soft surfaces that never get a turn: carpet tiles, upholstered seating, fabric acoustic panels, the underside and seams of banquette seating in a breakout area, curtains and blinds. These are the reservoir on a corporate floor, they load continuously through a week of several hundred people, and they are the reason two identical floor plates smell completely different. A deep clean cannot be done around occupants; a weekend is when it happens.
Service. The air conditioning work that is impossible to schedule mid-week - filters, coils, condensate trays and drain lines are ordinary service items on an ordinary schedule, and a unit that has run ten hours a day through a Pune June and July has been wet inside for weeks. In a managed building this may be the landlord's contractor and a request rather than an instruction, which is one more reason to plan it a fortnight out rather than on the day.
Then, and only then, fragrance - and it is the smallest decision of the day. Set the weekend level, confirm the closed-day schedule is off, and check that the unit is where you left it and out of the supply airstream. That is a ten-minute job. If you find yourself spending an hour of a Saturday on the diffuser and ten minutes on the pantry, the priorities have inverted and the floor will tell you so on Monday.
One honest commercial note. A great deal of what I have just listed is free or already in somebody's contract, and none of it is something I sell. That is not modesty; it is the order, and the order is the most useful thing SOSA can give a facilities team. When a floor is genuinely clean, aired and serviced and still has no character of its own, that is when a register earns its place - and that is a real and worthwhile thing, at a moderate and honest scale.
- Ask facilities whether the air handling runs a different pattern outside core hours.
- Write three levels: weekday, weekend and closed - and make the closed one off.
- Schedule them on the app rather than letting anyone nudge a dial on the day.
- Spend the quiet day on the pantry, the deep clean, the airing and the AC service.
One register, three levels, and what a quiet weekend is actually for
The register does not change between a Tuesday and a Saturday. The level does. That distinction is the single most useful thing in this section, because the temptation on a corporate floor is always to solve a scheduling problem with a different blend, and a different blend solves nothing - it just means your building smells like two buildings.
One register, held. Consistency is what makes a space recognisable, and recognisable is the honest thing that ambient scent does. A floor that smells the same on a Saturday as on a Tuesday, at a lower level, is a floor with a character. A floor that smells of one thing on a weekday and another at the weekend has no character; it has a rota.
Now the shortlist, from the seven registers in the water-based Hotel Collection, each SOSA's own hotel-inspired interpretation - SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand. For a large corporate floor the steer is narrow and it is a context steer: dry, clean, unsweet, low, and identical every day. Quiet Luxury is white tea, bergamot and cedar, hushed and polished, and it is the corporate default given one decision and no information - it holds a little presence across a large connected volume without becoming the thing anybody thinks about twice a day, five days a week. Forest Suite is cedarwood, vetiver and green leaves, grounding and green, and it is the driest of the shortlist, which matters more than it sounds: dry recedes and sweet accumulates, and accumulation is exactly the failure mode of a still weekend floor. White Tea Serenity is white tea, aloe and cedar, clean and weightless and spa-like, and it reads as clean rather than as scented, which suits a pale, minimal fit-out where anything with weight would sit oddly.
The ones I would keep off a corporate floor entirely. Lobby Bar is citrus, pepper and amber, bold and playful and after-dark - a quiet theatrical register is still theatrical, and a Saturday morning with four people in is not the occasion. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush accumulates over a still weekend in a way that dry does not. Warm Welcome is citrus, floral and sandalwood, a genuine hotel-threshold register, which is a fine argument for a hotel lobby and a poor one for a room the same people occupy all week. Tea Garden is jasmine, green tea and white tea and the least risky floral in the collection; I would still keep floral weight off a floor where a few hundred people have no choice about being there.
I will not rank the seven against each other on measured throw or longevity. SOSA does not publish that comparison, and the variables that dominate on your floor - connected volume, ceiling height, how hard the air handling is working on the day in question, how many people are in and where the unit sits relative to a supply grille - belong to your building rather than to the blend.
Now the settings, written as a table you can actually put in a document. Weekday: your calibrated level, set for the person waiting twenty minutes in the reception rather than the one walking in, running only during the hours the floor is genuinely occupied. Weekend working day: reduced, over a shorter window that starts when the weekend team actually arrives rather than at the weekday hour, and covering only the volumes that are in use - if the third floor is empty on a Saturday, the third floor gets nothing. Closed day: off. Not low. Off. There is no arrival experience to build on a day with no arrivals, and a closed floor accumulating for thirty hours with reduced air movement is worse on Monday, not better.
And underneath those three, two seasonal settings. A monsoon level and a dry-heat level, because a Kharadi floor in the second week of July is closed, humid and slow while the same floor in the third week of April is dry and having its air moved hard against average highs near 38 degrees C. Review them at the season change, change them deliberately, write the date you changed them. The failure mode this prevents is the slow upward drift that happens in every building where the level is adjusted by whoever is standing nearest to the machine on a bad morning.
One standing arrangement, at the weekend more than any other time. Anyone on duty can switch a named unit off without asking a manager and without justifying it. A weekend team of six has the highest per-head exposure in the building that day and the fewest colleagues to compare notes with. A reported reaction is a recalibration signal rather than a tolerance problem, no health or allergy claim is made in either direction, and nobody is ever addressed about how they personally smell.
| Scent | Why it suits the mood |
|---|---|
| Weekday · your calibrated level, occupied hours only | One register - Quiet Luxury, Forest Suite or White Tea Serenity - in the reception and connected client-facing volume, at a level set for the visitor who has been waiting twenty minutes rather than the one walking in. Scheduled to the hours the floor is genuinely occupied, not to the hours the lights are on. |
| Working weekend · reduced, shorter window, fewer volumes | Same register, lower level, and a window that starts when the weekend team actually arrives. Scent only the volumes in use: an empty floor gets nothing. The skeleton crew has the highest per-head exposure in the building that day, which is an argument for less rather than more. |
| Closed day · off, and off means off | Not low. Off. There is no arrival experience on a day with no arrivals, and a closed floor with reduced air movement accumulating for thirty hours reads worse on Monday, not better. Doored meeting rooms in particular should be off over a weekend, because a 57 cubic metre volume with nothing moving through it accumulates. |
| The weekend work itself · where the real result comes from | Pantry sink, drain, fridge, machine trays and the space behind the bin. Waste out of the building. Carpet tile and upholstery deep clean. The floor aired properly. The air conditioning service that cannot happen mid-week. Source, then ventilation, then cleaning, then fragrance - and a quiet day is when the first three are cheap. |
So the buying answer, and it is mostly about the timer rather than the machine. For a connected reception and client-facing volume on a large-format floor, the waterless SOSA Vaayu at ₹11,999 is the commercial answer: cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue, 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 published Bluetooth app and timer is the feature that makes this whole page implementable. Three written settings and two seasonal variants are an idea until something can hold them; a schedule that follows your occupancy is what turns them into how the building actually runs. 400ml tank, freestanding or wall and HVAC mount, DC 12V / 1A at 5W so it needs a live socket, CE, RoHS and SGS.
For a single doored room - a client meeting room you want treated separately, or a small weekend-staffed area - do not buy the same machine again. An ultrasonic is usually the whole purchase: a Boond at ₹899 or a Sukoon at ₹1,899, 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. Two systems, and they are not interchangeable: the ultrasonics are water-based cool-mist machines, while the Vaayu and 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 - run waterless nebulising oil. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. And on a Pune monsoon weekend there is a plain design reason to prefer waterless: the ultrasonics put a small amount of moisture into the room they sit in, which in a closed, humid, still floor is the wrong direction. A design preference, never a claim to control humidity, dehumidify or protect anything, because no SOSA product does that.
If what you want somewhere is no plug, no noise, no schedule and nothing to switch off, the SOSA reed diffusers are their own registers rather than Hotel Collection ones: Mountain Breeze ₹849 is Himalayan pine, sage and cedar; 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 at ₹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 floor - and it has no weekday or weekend setting at all, which on a small reception counter is occasionally the entire argument for it.
To go deeper on what this page only touches: if the weekend question is really about the hours after everyone has gone home, the answer and the reasoning are in whether a commercial scent machine should keep running in a Kharadi managed office after 8 PM. If some of your volumes stay stubbornly neutral whatever you do, the mechanism is in why a Kharadi office reception scents well while the meeting rooms stay neutral. And if the underlying brief is that the floor should feel like somewhere in particular rather than like every other corporate floor, most of that answer is not fragrance, which is the point of making a premium Kharadi office feel different from every other glass-and-AC corporate office.
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. Run hours are one of the things that genuinely drive the first three, which is a reason to schedule honestly rather than a reason for me to quote you a number I do not have. Send your floor plan, ceiling height, weekday and weekend headcount and your occupied hours to SOSA on WhatsApp at +91 96192 18531. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition is a real SOSA service discussed there rather than priced on a page - although the cheaper honest answer comes first, which is that one of the seven registers held consistently already is a signature, because consistency makes a signature and uniqueness does not.
The SOSA scenting range
SOSA sells two different systems and one of the commonest mistakes is mixing them up. Size by the connected air volume of the room you are actually scenting - which in a boutique means the connected retail floor plus any viewing room that has a door of its own - floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres. A door that stays shut ends one volume and begins another.
| Machine | System | What it is for | Price |
|---|---|---|---|
| SOSA Boond | Ultrasonic · water-based | A small desk or corner unit for one enclosed room - runs the water-based Hotel Collection | ₹899 |
| SOSA Sukoon | Ultrasonic · water-based | A larger ultrasonic for a reception or consultation room - Hotel Collection from ₹299 | ₹1,899 |
| SOSA Megh | Ultrasonic · 6L tank | A large-tank ultrasonic for a bigger lounge that runs all day | ₹3,499 |
| SOSA Vaayu | Waterless cold-air nebulising | The commercial machine - approx 1000 m3 of connected air, Bluetooth app and timer, no water and no humidity | ₹11,999 |
| SOSA Aangan | HVAC nebulising | Ducted scenting for approximately 8,000 to 10,000 sq ft | ₹25,999 |
| SOSA Meenar | HVAC nebulising | Ducted scenting for approximately 12,000 to 18,000 sq ft | ₹38,500 |
Two systems, and they are not interchangeable. The ultrasonics - Boond, Sukoon and Megh - run the water-based Hotel Collection from ₹299. Vaayu and the HVAC machines run waterless nebulising oil; the ₹299 water-based bottle never goes into a Vaayu. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is independent and not affiliated with any hotel brand. A portion of every order supports girl-child education through Nanhi Kali.
- Vaayu ₹11,999 - waterless cold-air nebulising, approx 1000 m3 connected air, Bluetooth app and timer, 400ml tank, freestanding or wall / HVAC mount, DC 12V / 1A, 5W, mains powered, CE / RoHS / SGS.
- 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.
