Here are the two numbers that decide the page, and I would rather put them first than build up to them. A consultation cabin of about 100 sq ft with a 9 ft ceiling is 100 multiplied by 9, which is 900 cubic feet; divided by 35.3 that is about 25 cubic metres. A reception of about 600 sq ft with a 12 ft ceiling is 7,200 cubic feet, about 204 cubic metres. The cabin is roughly eight times smaller than the reception it opens off. Put the same output into both and the cabin gets something like eight times the concentration, which is a straightforward consequence of dividing by a smaller number rather than an opinion about fragrance.
Then the second variable, which pushes the same way and is often the stronger of the two. The cabin holds two or three people for a long structured conversation about a significant purchase - figures, options, documents, a negotiation that is not hurried - while reception holds more people for much less time each and has doors cycling. Long dwell and small volume both mean less, never more. A level that is pleasant when you put your head round the door at minute one is tiring at minute fifty, and in a cabin it is the customer who has to sit in it, with the door shut, while doing something that requires attention.
I want to name the instinct this contradicts, because almost every owner I talk to has it. The cabin is where the important conversation happens, so the cabin should have more. That instinct is the single most reliable way to make a small room unpleasant to sit in for an hour. Importance is not a physical property of air. Volume and dwell are.
And the discipline that makes it work: one register throughout, with different written levels per room - never two registers. Two registers in adjoining rooms meet in the doorway between them, and in that doorway a customer gets a third smell that nobody chose, nobody specified and nobody can control. Reception opens into cabins. People walk through that boundary with the door open, both ways, all day. One register, several numbers written on a card.
The standing limits before the detail. I will not tell you that a scent sells anything - not enquiries, test drives, deposits, referrals or transaction value, and not implied either; the honest ceiling is improved evaluations of a space and its service, longer dwell and stronger recall of a space, at moderate effect sizes. No claim is made about what a fragrance does to a person, and none about a vehicle, its interior, its finish, what it smells of or how it is protected - nothing is ever put into one. And fragrance adds scent and has never removed any: no SOSA product treats, filters, dries, dehumidifies or purifies air, so a smell you do not want is a source question, then a ventilation question, then a cleaning question, with fragrance fourth.
Can the cabins use a different scent from reception? No - one register, different written levels. This is the commonest avoidable mistake in multi-room scenting and the reason is geometric rather than aesthetic. Two registers meet in the doorway between the two rooms, and in that doorway a person receives a third smell that nobody chose and nobody can control. A dealership reception opens directly into its cabins and people walk through that boundary with the door open several times an hour, so the collision is not occasional, it is the normal condition. Choose one of the seven registers in the water-based Hotel Collection from ₹299, then write a different setting for each room on a card: reception highest, lounge below it, cabins lowest.
How much lower should a cabin actually be set? SOSA does not publish a formula and I will not invent one, because the honest variables are your room, your door discipline and your building rather than a ratio. What I can give you is the method. Set reception first and get it right using somebody who has been outside ten minutes and does not work for you, asked an open question. Then set each cabin below that, and test it the way it is actually used: sit in the cabin with the door shut for the length of a real consultation, not for thirty seconds. The judgement is made at minute fifty, not minute one. If a customer can name what the room smells of, it is too high. And some cabins honestly take nothing at all, which is a legitimate answer rather than a failure.
The second reason is dwell, and in this bank it is usually the stronger of the two. Reception is a room people pass through: they arrive, they are greeted, they wait a few minutes, they move on, and the entrance doors cycle while they do it. A consultation cabin is a room people sit in, with the door shut, for a long structured conversation about a significant purchase - figures, options, comparisons, documents, a negotiation that should not be rushed. Exposure is a product of level and time, and the cabin multiplies a small volume by a long occupancy. A level that is pleasant at minute one is tiring at minute fifty. The person carrying that is the customer, and they are trying to concentrate on numbers while they do it.
The third reason is headcount, which is quietly important and rarely mentioned. A busy reception has people in it, and people in a room change how a level is received - a fuller room already has more in it than an empty one. A cabin has two or three occupants, usually seated, usually still. So the cabin is the room where an over-set level has the least competition and the most time to be noticed. Everything about the room points the same way.
Now the instinct I am arguing against, because it is nearly universal. Owners look at the cabin and see the room where the serious conversation happens, and they conclude it should be the most finished, most considered, most present room in the building. The first two of those are right and worth spending on: better seating, better light for reading documents, a door that shuts properly, a table at the right height, no interruptions. The third is a category error. Importance is not a physical property of air. Volume and dwell are, and both of them are telling you to go down.
How much lower, honestly. SOSA does not publish a formula and I am not going to invent a ratio to sound precise, because the real variables are your room, whether the door is genuinely kept shut, and your building. The method is what I can give you. Set reception first and get it right, judged by somebody who has been outside for at least ten minutes and does not work for you, asked an open question rather than "can you smell the fragrance?" which plants the answer. Then set each cabin below it, and test the cabin the way it is used: sit in it with the door closed for the length of a real consultation. If a visitor can name what the room smells of, it is too high. And be willing to land on nothing - a cabin used for long financial conversations with the door shut is a room where the honest answer is sometimes no fragrance at all, and that is a legitimate result rather than a failed installation.
And one register, several written levels, never two registers. Two registers in adjoining rooms collide in the doorway between them and produce a third smell nobody chose. A reception that opens into cabins is that doorway several times an hour. Choose one of the seven in the water-based Hotel Collection from ₹299, then write the unit, the register, the exact setting and the hours for each room on a card inside the cupboard the unit lives in. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, do this, and it needs a tape measure rather than a budget. Measure reception and every cabin, write the ceiling height next to each, and do the two multiplications on one sheet: area times height gives cubic feet, cubic feet divided by 35.3 gives cubic metres. Put the numbers in a column from largest to smallest. That column is your level ladder, and it is the only defensible basis for deciding which room gets what. Most people have never seen their own rooms compared that way and are surprised by how wide the gap is.
Then do the sitting test, which is the half of this that arithmetic cannot give you. Sit in a cabin with the door shut for the length of a real consultation on a busy day. Not thirty seconds with the door open - the full duration, door closed, doing something that takes attention. Rooms that seem fine when you look in are a different proposition at minute fifty, and the customer experiences the second version rather than the first.
Now the harder part, which is who is allowed to judge. You, your sales staff and anyone who sits in those cabins all day cannot report the air to anybody by the second hour of the morning. That is ordinary adaptation, not carelessness, and it has two consequences that both point down. You will systematically tend to set the level too high, because you cannot smell what a visitor smells. And the people who spend the most hours in the smallest rooms - your consultants, sitting in a 25 cubic metre box with the door shut for a full day - carry an over-set level without being able to detect it. They are the most exposed people in the building by a wide margin. So the standing arrangement, written down on day one: anyone can switch a named unit off without asking a manager, and nobody has to justify it afterwards. A reported reaction is a recalibration signal rather than a tolerance problem. No health or allergy claim is made here in either direction.
Then guard against drift, which is the failure mode that undoes a correct ladder. Week one both rooms are right. Week three somebody says the cabin seems weak and turns it up, and they are not lying - they have adapted. By month four the cabin is running above reception, which is the exact inversion this page exists to prevent. Writing the numbers down is the entire defence: any change is a decision that needs a reason and a date, not something done on a Tuesday because a room felt flat.
And a seasonal note that is specific to this city rather than decorative. Your cabins probably open off a reception that opens off a showroom floor, and that floor takes on whatever is outside every time the vehicle door is used: hot dry air in April and May, when May's mean daily maximum runs near 39.9 degrees C and the year's humidity trough falls in the hottest months; wet air in July and August; cool damp air from late November to February, when January days reach only about 21.4 degrees C and fog is common through December and January. Three written settings on a card for each room. Never three registers, and never less ventilation.
The arithmetic, the dwell and the doorway - three reasons the cabin runs below reception
Three things decide the level in a cabin relative to reception, and none of them is how important the conversation in it is. The first is volume, which is arithmetic and settles the direction immediately. The second is dwell, which usually settles the magnitude. The third is the doorway between the two rooms, which settles the question of whether they can have different registers at all - and the answer is no.
Start with the arithmetic, done by hand with stated ceiling heights. Consultation cabin, 100 sq ft at 9 ft: 100 multiplied by 9 is 900 cubic feet; 900 divided by 35.3 is about 25 cubic metres. A smaller cabin, 80 sq ft at 9 ft: 720 cubic feet, about 20 cubic metres. A larger one, 120 sq ft at 9 ft: 1,080 cubic feet, about 31 cubic metres. Now the comparison. Reception, 600 sq ft at 12 ft: 7,200 cubic feet, about 204 cubic metres. A larger reception, 900 sq ft at 12 ft: 10,800 cubic feet, about 306 cubic metres. And for completeness, the other small room in this building: a handover lounge, 300 sq ft at 10 ft, is 3,000 cubic feet, about 85 cubic metres.
Line them up and the ladder writes itself: reception at about 204, the handover lounge at about 85, the cabin at about 25. Reception is roughly eight times the cabin, and if your reception is the larger one it is about twelve times. Nothing about which register you choose changes that ordering, and no preference outranks it.
Set the whole ladder against a 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. Reception is about a fifth of that figure. The lounge is under a tenth. The cabin is about one fortieth. Which is the recurring finding of this whole bank stated as sharply as it ever gets: the machine is not your constraint, the setting is, and in a room of 25 cubic metres the margin for error on the setting is the narrowest in the building.
Now the word that governs everything: connected. A coverage rating assumes one connected body of air, and scent does not travel through a closed door. So each cabin whose door genuinely stays shut is its own volume, which is exactly what allows it to hold a different level from reception - and which also means a cabin whose door is propped open all afternoon is not a separate volume at all and cannot hold a separate level. Walk the building and mark the doors that stay shut in practice rather than in principle. And the same rule, applied outward, is why the showroom floor is not the scented room: a large vehicle door in use is a continuous air exchange, so the floor is a volume being refreshed from outside rather than held. No coverage figure applies to it and no machine count changes that. Never reduce ventilation, restrict an opening or alter a building's air handling so a fragrance lasts longer, in that phrasing or any softer one. The people responsible for your building's air decide how it is ventilated, and their decision overrides every recommendation here.
The cabin. 100 sq ft at a 9 ft ceiling. Multiply: 900 cubic feet. Divide by 35.3: about 25 cubic metres. If your cabins are smaller, 80 sq ft at 9 ft is 720 cubic feet, about 20 cubic metres. If larger, 120 sq ft at 9 ft is 1,080 cubic feet, about 31 cubic metres. Note how low all three ceiling heights are compared with the rest of the building: cabins are usually built into a shell with a dropped ceiling, so they are short as well as small, and both dimensions are working against you.
Reception. 600 sq ft at a 12 ft ceiling. 7,200 cubic feet, about 204 cubic metres. A larger reception at 900 sq ft and 12 ft is 10,800 cubic feet, about 306 cubic metres.
The ratio, which is the point. About eight to one in the ordinary case and about twelve to one in the larger one. Whatever output produces a correct reception is, dropped into a cabin unchanged, being divided into a volume a fraction of the size. This is not a claim about fragrance behaviour or a manufacturer's opinion. It is what happens when you divide by a smaller number.
And against the published figure. A Vaayu is rated for approximately 1000 cubic metres of connected air. A cabin at about 25 cubic metres is roughly one fortieth of that. Nobody has ever had a 25 cubic metre room improved by more output; every problem in a room that size is on the other side of the dial. This is also why an ultrasonic is frequently the honest purchase for a single cabin rather than a commercial machine - a SOSA Boond at ₹899 or a SOSA Sukoon at ₹1,899 running the water-based Hotel Collection from ₹299 is a smaller and more appropriate tool for a very small volume.
One caveat that changes the arithmetic. If the cabin has no door, or a door that is never shut, then it is not a 25 cubic metre volume at all - it is an alcove off a 204 cubic metre room, and it cannot hold its own level no matter what you set. Measure the doors before you measure the rooms.
What reception actually is. A room people pass through. They arrive, they are greeted, they wait a few minutes, they are taken somewhere. The entrance doors cycle. There are other people in it, and a fuller room already has more in it than an empty one. Exposure per person is short and interrupted.
What a cabin actually is. A room people sit in with the door shut while something detailed and consequential is worked through: figures, options, comparisons, documents, a negotiation nobody wants rushed. Two or three occupants, seated, still. Exposure is level multiplied by time, and this room maximises time in the smallest volume available.
The consequence, stated as a design rule. Set the cabin for minute fifty, not for the moment the door opens. The test everybody runs by default is the head-round-the-door test, and it is the wrong test for this room: it samples the first ten seconds of an experience that lasts an hour. A level that is pleasant at minute one is tiring at minute fifty, and the person who finds that out is the customer, in the middle of concentrating on something that matters to them.
And then repeat exposure, which nobody costs in. Your consultant is in that 25 cubic metre room for most of a working day, with the door shut, several days a week. That makes them the most exposed person in the building by a wide margin - many times the exposure of any customer - and simultaneously one of the least able to report on it, because adaptation means they stop detecting it within the first hour or two. Those two facts together are why the level in the smallest rooms must be set most conservatively and why the off-switch rule matters most here. Anyone can switch a named unit off without asking a manager, and a reported reaction is a recalibration signal rather than a tolerance problem. No health or allergy claim is made in either direction.
Which is also why "nothing" is a real answer for some cabins. If a cabin is used for hour-long financial conversations with the door shut, if it is occupied by the same person all day, or if it is very small, the honest recommendation is frequently no fragrance in that room at all - scent reception and the handover lounge, and let the cabins be quiet. I would rather write that than sell three more units. Choosing not to scent a room is part of designing the installation, not an admission that the installation failed.
Different levels, yes. Different registers, no. The reasoning is geometric rather than aesthetic. Two rooms that share a doorway share air every time that door opens, and where two registers meet a person receives a third smell - one that nobody chose, nobody specified, nobody can predict from the two ingredients and nobody can control. In a dealership, reception opens directly into the cabins and into the handover lounge, and people move across those boundaries several times an hour with the doors open. So the collision is not an edge case; it is the normal state of the building. One register everywhere, and then numbers.
What "written levels" means in practice. A card inside the cupboard each unit lives in, with four things on it: the unit, the register, the exact setting and the hours. Not a note in somebody's phone, not an instruction given verbally to whoever is on the desk. The card is what makes the ladder survive staff changes, and it is the only defence against the failure mode below.
Drift, which will otherwise invert your ladder within four months. A level in a commercial room does not stay where you put it, because the people adjusting it cannot smell it any more. Week one reception and the cabins are correctly set. Week three, a consultant who has been in the cabin since nine says it seems weak and turns it up - and they are not lying, they have adapted more thoroughly than anyone in the building because they are in the smallest room with the door shut. By month four the cabin is running above reception, which is precisely the inversion this page exists to prevent, and nobody who works there can detect it. Write the numbers down. Treat any change as a decision with a reason and a date.
The order of setting, which matters. Set reception first, because it is the largest and most forgiving and because everything else is defined relative to it. Then set the handover lounge below reception. Then set the cabins below that. Do not set the cabins first and work outward, because a correct cabin setting is very low and using it as a reference tends to produce a reception nobody notices at all.
And the test, which is the only one worth running anywhere in this building. Somebody who has been outside for at least ten minutes and does not work for you, walked into the room and asked an open question - what do you notice? - rather than "can you smell the fragrance?", which plants the answer. If they can name what the room smells of, it is too high. Run that test in reception and then, separately, in a cabin with the door shut after they have been sitting in it a while. Two rooms, two tests, two numbers.
- Measure both: area times ceiling height, divided by 35.3, written in one column.
- Set reception first, judged by somebody who has been outside for ten minutes.
- Set each cabin below it, then test by sitting in it with the door shut for an hour.
- One register, a number per room on a card. Anyone may switch a named unit off.
One register, two written levels, and the rooms that honestly take nothing
So: one reception of about 204 cubic metres, cabins of about 25 each, doors between them, and one register across the lot. What goes in, and how the numbers are arranged.
The ladder first, because it is the actual product here. Reception highest. Handover lounge, at about 85 cubic metres, below reception. Cabins, at about 25, lowest of all - and for some cabins, nothing. Set in that order, reception first, because everything else is defined relative to it and because a cabin setting is too low to be a useful reference point. Write each number on a card inside the cupboard the unit lives in, alongside the unit, the register and the hours.
Then the register, which matters far less than the ladder. There are seven 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 building whose smallest rooms are long-dwell and doored, the shortlist is narrow and it is a context steer rather than a matter of taste. Quiet Luxury is white tea, bergamot and cedar - hushed, polished and unsweet, and what I would run given one decision and nothing else to go on, because it carries a little presence in a reception without becoming the thing anybody is aware of at minute fifty in a cabin. White Tea Serenity is white tea, aloe and cedar - clean, weightless and spa-like, the register that most readily reads as clean rather than as scented, which is the right objective in a room where somebody is reading figures. Forest Suite is cedarwood, vetiver and green leaves - the driest of the three and the one most likely to be received as a property of the building rather than as a decision somebody made. In a 25 cubic metre room that is a real advantage, because there is nowhere for an obvious register to hide and an hour is a long time to notice one.
The ones I would keep out of a cabin. Lobby Bar is citrus, pepper and amber, bold and after-dark; a theatrical register turned down is a quiet theatrical register rather than an inconspicuous one, and a cabin is the least forgiving room in the building. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush accumulates across an hour in 25 cubic metres in a way that dry simply does not. Warm Welcome is citrus, floral and sandalwood, a genuine hotel-threshold register, which is an argument for considering it in a reception and against it in a room nobody is crossing. Tea Garden is jasmine, green tea and white tea, the least risky floral in the collection; even so, in a doored 25 cubic metre room held for an hour I would take the dry options first.
Note what just happened there, because it is the one place register choice interacts with this page's argument. A register that suits a reception is not automatically the one that suits a cabin - and yet you still use one register across both, because the doorway rules out two. The resolution is to choose the register that survives the hardest room, which is the cabin, and then set it higher in the easier one. Pick for the 25 cubic metre box, not for the 204 cubic metre lobby.
I will not rank those seven against each other on measured throw or longevity. SOSA does not publish that comparison, and the variables that dominate belong to your building rather than to the blend. There is also no automotive, leather or technical register in the commercial range: the machines run the seven Hotel Collection registers and nothing else, and the reeds are their own five scents. Bespoke composition is a real SOSA service discussed on WhatsApp rather than priced on a page - but the cheaper honest answer comes first, which is that one of the seven held at written levels every trading day already is a signature, because consistency makes a signature and uniqueness does not.
| Scent | Why it suits the mood |
|---|---|
| Reception · about 204 cubic metres, short dwell, doors cycling | 600 sq ft at a 12 ft ceiling is 7,200 cubic feet, about 204 cubic metres - roughly a fifth of a Vaayu's published approximately 1000 m3. Short dwell per person, more people in the room, and entrance doors moving air. This is the most forgiving room you have and the one to set first, because every other number is defined relative to it. It still gets a low setting by any general standard; forgiving is not the same as loud. |
| Handover lounge · about 85 cubic metres, long sitting, door shut | 300 sq ft at a 10 ft ceiling is 3,000 cubic feet, about 85 cubic metres, under a tenth of the published figure. Smaller than reception and occupied for far longer, so it sits below reception on the ladder. Set it for minute fifty of a sitting rather than for the moment somebody opens the door, and remember the customer will be back for service, so set it for the fourth visit rather than the first. |
| Consultation cabin · about 25 cubic metres, an hour, two or three people | 100 sq ft at a 9 ft ceiling is 900 cubic feet, about 25 cubic metres - roughly one fortieth of the published figure and about eight times smaller than reception. Long dwell, few people, door shut, and a consultant in it most of the working day. This is the lowest rung in the building and the narrowest margin for error. Judge it seated, with the door closed, at minute fifty. |
| Nothing at all · some cabins, the showroom floor, work and wash bays | Not a lower setting - nothing. A cabin used for hour-long conversations with the door shut, or occupied by the same person all day, honestly takes no fragrance at all, and choosing that is part of designing the installation rather than a failure of it. The showroom floor has a vehicle door cycling and is a volume being exchanged, so no coverage figure applies. Work bays, wash bays and parts stores are source-and-ventilation questions. And nothing is ever put into a vehicle. |
So the buying answer, sized to the rooms rather than to the building. For a single cabin of about 25 cubic metres or a single lounge of about 85, an ultrasonic is frequently the whole purchase: a SOSA Boond at ₹899 for a compact room, or a SOSA Sukoon at ₹1,899 for something larger, both running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999 and 300ml also available. A SOSA Megh at ₹3,499 has a 6 litre tank for a larger room that runs all day. The pack of seven 15ml bottles at ₹1,799 is the sensible way to audition registers in your own rooms rather than from a description - and audition them in the cabin rather than in reception, because the cabin is the room that will expose a register you chose for the wrong reasons. Judge on day five rather than the first afternoon.
If reception, the lounge and the cabins genuinely form one connected or near-connected group, the commercial machine is the SOSA Vaayu at ₹11,999: waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue, which is a plain design preference worth stating in a city with two damp stretches in the year rather than one. Rated for approximately 1000 cubic metres of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. The Bluetooth app and timer is most of the value here, for a reason that has nothing to do with convenience: it is what lets you write a setting down and keep it, running in trading hours only, with one setting for a dry May, another for a wet August and another for a foggy January. 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 two systems are not interchangeable: the ultrasonics are water-based cool-mist machines, while the Vaayu and the ducted Aangan at ₹25,999 (approximately 8,000 to 10,000 sq ft) and Meenar at ₹38,500 (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 in a room of 25 cubic metres there is a serious case for no machine at all. The SOSA reed diffusers are their own registers rather than Hotel Collection ones - Mountain Breeze ₹849 is the driest, with Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799 and Fresh Brew ₹849 completing the set, 130ml from ₹1,249 and lasting about 6 to 10 weeks. A reed is passive and local: no plug, no noise, nothing to switch off, and it scents the few feet around it rather than filling a room. In the smallest long-dwell room in a building, that limitation is frequently the feature. The one thing to be careful about is that a reed is a different register from your Hotel Collection one, so if the cabin opens into a scented reception you are back in the doorway problem - which is another argument for the cabin simply taking nothing.
To go deeper: the whole-dealership version of this question, including which rooms get nothing, is in whether a premium car dealership in Lucknow should have a signature scent at all. The sequence and the room design around a collection, where the air comes last and lowest, is in how the delivery experience should be designed around a customer collecting a new car. And if the question is where a unit physically stands once you have chosen the rooms, that is where a Vaayu should actually be placed in a showroom with large vehicle doors opening constantly.

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
Most of what is written about commercial scenting assumes you are building something from nothing - a new brand, an empty room, a customer who has never met you. Almost none of it is written for the business I actually get asked about most often in a city like Lucknow: the one that has been there for thirty years, that people already trust, where the founder's son or daughter is now looking at the place and thinking it should feel more like what it is worth.
That business has a completely different problem, and it is worth naming plainly. You are not trying to create an impression. You are trying not to damage one. A customer who has come to you since before you were running the place has a version of your shop in their head, and it is a good version - that is why they keep coming. If they walk in one morning and the room announces that something has changed, you have spent a real asset to buy a compliment. So my advice to legacy businesses is almost embarrassingly conservative: go so low that nobody remarks on it. Not low as a compromise - low as the specification.
The rest is the same as it always is, and it is the least commercial thing I say. Fragrance adds a smell; it has never once removed one. So if the showroom smells of damp in August, or the lobby carries the kitchen, or the new fit-out is still off-gassing, a machine gives you both smells at once and most people find that worse than the original. Source, then ventilation, then cleaning, and only then a quiet character held at the same level every single day - because in a business built on being the same place it has always been, consistency is the entire product.
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 Lucknow's seasons, localities and crafts are general and qualitative; every figure about a specific building must come from that building. Nothing here claims any association with, or endorsement by, any craft body, heritage authority or local institution. 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.
