Start with the numbers, because they are the reason the instinct exists. A double-height entrance of 800 sq ft at a 20 ft ceiling is 16,000 cubic feet, which divided by 35.3 is about 453 cubic metres. A larger one at 1,500 sq ft and 20 ft is 30,000 cubic feet, about 850 cubic metres. Now do the same footprints at an ordinary 10 ft ceiling: 8,000 cubic feet and about 227 cubic metres, and 15,000 cubic feet and about 425. The height doubles the volume, and nothing on the floor plan tells you that. A developer sizing by square footage has under-counted their entrance by half without ever making an error.
So the first correction is to compute the real number. But the second correction is the one that actually solves the problem, and it is the point of this page. You are not trying to scent that volume. You are trying to scent the part of it a person occupies, which is the bottom six feet. Do that arithmetic too: 800 sq ft at 6 ft is 4,800 cubic feet, about 136 cubic metres. 1,500 sq ft at 6 ft is 9,000 cubic feet, about 255 cubic metres. Those are the numbers that matter, and they are a fraction of the headline figure.
Which gives the sentence worth taking away from this page. Scenting the roof void is paying to condition air that nobody breathes, and turning the output up to reach the top of a twenty-foot volume is precisely how a gallery ends up over-scented at head height while somebody still complains that it does not carry. The answer is placement, not output: low, inward, out of the entrance airstream and out of any air conditioning supply airstream.
The standing limits, before the working. I will not tell you that a scent affects a booking, a site visit, an enquiry or a buyer's decision; the ceiling is improved evaluations of a space and its service, longer dwell and stronger recall of a space, at moderate effect sizes. Fragrance adds a smell and has never removed one, and no SOSA product treats, filters, dries, dehumidifies or purifies air - not the Vaayu at ₹11,999, not an ₹899 Boond, not a ₹749 reed. And never reduce ventilation in a tall room to make a fragrance hold. A double-height gallery with cycling doors is genuinely hard to scent, and less air is never the answer to that.
Why is raising the machine output the wrong response? Because it does not correct the thing that is actually happening, and it makes a different problem. In a tall room the upper volume is not a barrier to be overcome, it is simply space, and pushing more output at it scents more of the air that is above everybody's head. Meanwhile the level in the occupied band climbs, so you end up with a gallery that is over-scented at head height and still feels thin at the threshold, because the threshold is being diluted by the doors rather than by the height. Raising output also lands on your own staff, who stand in that room eight to ten hours a day and cannot report the level accurately because adaptation is ordinary. The correct variables are placement, level and schedule.
Where exactly should the unit not go? Three places. Not in the entrance airstream - the first several feet inside a cycling door are effectively outdoor air, and a unit placed there is either unnoticeable or is being turned up to compensate, which over-scents the rest of the room. Not in an air conditioning supply airstream, because output dropped into a supply stream is carried away and thinned before it reaches the part of the room people stand in. And not high, whether that means on a mezzanine edge, a high-level bracket or anywhere aimed upward, because the air above about six feet is not air anybody is using. Beyond that, avoid a dead corner with no movement at all, which produces a local pocket and nothing elsewhere.
The arithmetic, because almost nobody has done it. Take a double-height entrance of 800 sq ft with a 20 ft ceiling. Floor area multiplied by ceiling height gives 16,000 cubic feet; divided by 35.3, that is about 453 cubic metres. A larger one at 1,500 sq ft and 20 ft: 30,000 cubic feet, about 850 cubic metres. Now take the same two footprints at a normal 10 ft ceiling: 8,000 cubic feet and about 227 cubic metres, 15,000 cubic feet and about 425. The height has doubled the volume, and the floor plan looks identical. Set that against a SOSA Vaayu at ₹11,999, published for approximately 1000 cubic metres of connected air. A single-unit shop elsewhere in this bank sits at a fifth of that rating. A 1,500 sq ft double-height entrance at 850 is using most of it in one room, before the gallery behind it is counted at all.
So yes, the volume is genuinely large, and that is exactly why the instinct to raise output is so tempting and so wrong. Here is the correction, and it is the whole page. You are not trying to scent 453 cubic metres. You are trying to scent the part of it that a person is standing in, which is the bottom six feet. Do that arithmetic: 800 sq ft at 6 ft is 4,800 cubic feet, about 136 cubic metres. At 1,500 sq ft, 9,000 cubic feet, about 255 cubic metres. That is the air a buyer, an executive and a family walking to the model are actually in. Everything above it is architecture, and it is doing a visual job rather than an olfactory one.
Turning the output up does not target the occupied band, it targets everything. More output in a tall room means more scented air throughout the volume, including the fourteen feet that nobody will ever breathe. To get the occupied band to the level you want by this method, you have to over-supply the whole room, and two things follow. The head-height level climbs past where you would have set it if you could control it directly, which lands on your buyers and on your own staff. And you are running the machine continuously harder to condition air that has no occupant, which is a running cost with no corresponding benefit and it continues for the whole sales period.
What to do instead, in order. First, place low. Whatever is producing scent should sit at or near the level people occupy, not on a high bracket, not on a mezzanine edge, not aimed upward. Second, place inward. The first several feet inside a cycling entrance door are effectively outdoor air and no setting changes that; a unit placed near the doors is either unnoticed or is being turned up to compensate, which is the same mistake arriving by a different route. Put it deeper into the room, in the zone between the entrance and the model where people actually pause. Third, stay out of the air conditioning supply airstream. Output dropped into a supply stream is carried off and thinned before it reaches anybody, and the operator's response is invariably to raise the setting, which produces a strong pocket near the return and nothing where it is wanted. Fourth, avoid a genuinely dead corner, which is the opposite failure: a local pocket that reads strongly to whoever is beside it and not at all four metres away.
And if, having done all four, a single unit genuinely cannot hold the connected volume, the answer is still not a bigger number on one machine. It is a second unit placed in a different part of the same volume, both at the same low setting, so the room is served from two positions rather than pushed hard from one. Or, if your gallery runs on ducted air conditioning, 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 - distribute through the system the building already has. That is a decision for the people responsible for your building's air, and nothing on this page is HVAC advice. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, get the actual ceiling height of your entrance rather than the number in your head. Tall rooms are systematically under-estimated by eye, and the difference between an 18 ft and a 24 ft void is a third of the volume. Then multiply by the floor area of the double-height portion only - not the whole gallery, because the part under a normal slab is a different height and should be computed separately and added. A gallery with a double-height entrance and a single-height rear is two volumes stacked into one number, and doing them separately is the only way to get an honest total.
Then do the six-foot version of the same sum and write both numbers side by side on the same sheet. Seeing 453 next to 136 does more to settle the output argument than any amount of explanation, because it makes visible what everybody is paying for: about seventy per cent of that volume has no occupant in it at any point in the day.
Now a word on what tall rooms genuinely do, because I do not want to over-claim in the other direction either. Warm air rises, and a double-height room with a large glazed or lit upper volume will have vertical movement in it through the day, which does carry things upward away from the occupied band. That is a real reason a tall room feels harder to hold than a low one, and it is a real reason placement matters more here than anywhere else in a gallery. It is not a reason to fight it with volume. Work with the occupied band and let the upper volume do whatever it does.
The one thing that is never available as a solution, and I will say it plainly because tall rooms are where this suggestion surfaces. Never reduce ventilation, close a vent, shut a door, restrict extraction or ask anybody to run the air handling differently so that a fragrance holds longer in a tall space. Not in a closed-up foggy January morning, not in a wet August, not in a 39.9 degree C May when the cooling is running hard and clearing the room faster than you would like. A well-ventilated gallery is genuinely harder to scent and the correct responses are placement, a lower level and a schedule. Less air is never one of them, and a supplier who suggests it is serving the machine rather than the building.
And the standing rule for a staffed gallery, written into the operating notes. Anyone on the floor can switch a named unit off without asking a manager. Staff are in that room eight to ten hours a day against a buyer's forty minutes, they cannot report the level accurately because adaptation is ordinary, and a reported reaction is a recalibration signal rather than a tolerance problem. No health or allergy claim is made in either direction.
The arithmetic of height, and the part of the volume a buyer actually occupies
Three things decide a tall room, and machine capacity is the last of them. The first is the real volume, computed rather than assumed. The second is the occupied band, which is the only part of that volume worth conditioning. The third is placement, which in a double-height gallery does more work than in any other room type in this bank.
Here is the full set of numbers, and I would keep them on one sheet. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres.
800 sq ft at 20 ft: 16,000 cubic feet, about 453 cubic metres. The same footprint at 10 ft: 8,000 cubic feet, about 227.
1,500 sq ft at 20 ft: 30,000 cubic feet, about 850 cubic metres. The same footprint at 10 ft: 15,000 cubic feet, about 425.
The occupied band, 800 sq ft at 6 ft: 4,800 cubic feet, about 136 cubic metres.
The occupied band, 1,500 sq ft at 6 ft: 9,000 cubic feet, about 255 cubic metres.
Set those 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. Two things fall out. First, a large double-height entrance is one of the few rooms in this entire bank where a single machine is genuinely working near its published rating rather than at a fifth of it - which is worth knowing before somebody assumes one unit does the whole building. Second, and more usefully: the occupied band at 136 or 255 cubic metres is comfortably inside the rating with a great deal of room to spare, which is the arithmetic case for placement over output stated in numbers.
Then the word connected, which in a tall gallery is usually more generous than elsewhere. A coverage rating assumes one connected body of air, and a double-height entrance is typically open to the gallery floor beyond it, sometimes to a mezzanine and often to a stair. That means your connected volume is the entrance plus everything it opens into, computed at their own heights and added - which is how a developer ends up with a genuinely large number and reaches for the output dial. Add the volumes honestly, then apply the occupied-band correction to all of them, and the number stops being frightening.
Finally the entrance itself, which is the specific reason placement beats output here. A gallery door cycles constantly during opening hours, and every cycle exchanges a slug of air with outside. In a hot dry May at nearly 40 degrees C with cooling running hard, in a wet August, and on a foggy January morning when the building is shut up and the outside air is cold and damp, those exchanges behave differently - which is an argument for three written settings across the year, not for a permanently higher one. The first several feet inside that door are effectively outdoor air in every season. Nothing you buy changes that, and trying to overpower it is how tall galleries get over-scented everywhere except at the door.
Work it through once and it stays with you. An 800 sq ft entrance sounds modest and is the sort of footprint nobody would worry about. At a 10 ft ceiling it is 8,000 cubic feet, about 227 cubic metres, and it is indeed modest. At 20 ft it is 16,000 cubic feet, about 453 cubic metres, and it is twice the room. Nothing on the plan changed. The only difference is a dimension that does not appear in plan view at all.
Scale it up and the effect gets sharper. A 1,500 sq ft double-height entrance at 20 ft is 30,000 cubic feet, about 850 cubic metres. That single room is using most of a Vaayu's published approximately 1000 cubic metres of connected air, and the gallery it opens into has not been counted yet.
And a double-height gallery is usually not one height. The common arrangement is a tall entrance volume opening into a lower-ceilinged space where the model sits, sometimes with a mezzanine above. Compute those separately and add them: the double-height portion at its real height, the rest at its own, and the mezzanine as its own area at its own height. Doing the whole floor at a single assumed height is how the number comes out wrong in either direction, and wrong in either direction produces a bad decision.
The practical consequence of getting this right is not a bigger machine. It is knowing, before anybody starts adjusting settings, whether the room you are trying to hold is 227 cubic metres or 850. Those are different buildings and they take different approaches, and the difference is invisible until somebody climbs up with a tape measure or reads the section drawing rather than the plan.
One honest caveat, since we are being precise about numbers. A published coverage rating is a rating, not a guarantee about your specific room, and no rating survives contact with cycling doors, a supply airstream blowing across the unit, an open stair to a mezzanine, or a level set by somebody who adapted to it three weeks ago. The arithmetic tells you what you are dealing with. It does not tell you what setting to use, and no honest supplier will give you a setting from a distance.
Nobody in your gallery is above six feet. A buyer stands, walks, leans over the model, sits at a table. A family looks at boards on a wall. An executive walks them across the floor. All of that happens in a band from the floor to roughly head height, and everything above it is architecture doing a visual job. In a 20 ft room, about seventy per cent of the volume has no occupant in it at any point in the day.
Put it in numbers, because numbers end arguments. 800 sq ft at 6 ft is 4,800 cubic feet, about 136 cubic metres, against a total of 453. 1,500 sq ft at 6 ft is 9,000 cubic feet, about 255 cubic metres, against a total of 850. The band you care about is roughly three tenths of what you were about to specify for.
Now see what raising output actually does. It does not selectively fill the occupied band; it supplies the whole connected volume, including the void. To bring the occupied band up by this route you must over-supply everything, and the result is a room whose head-height level is higher than anyone would have chosen if they could have set it directly. Your buyers get that. Your sales team, who are in it eight to ten hours a day, get far more of it, and cannot tell you, because adaptation is ordinary and universal.
Placement is how you target the band instead. Put the source in the band. Low rather than high, at or near the level people occupy, not on a high bracket and not aimed upward. That is genuinely the entire mechanism, and it is why a correctly placed machine at a low setting outperforms a badly placed one at a high setting in a tall room, every time.
There is a second reason not to fight the void, which is thermal. Warm air rises, and a tall room with a bright upper volume has vertical movement through the day, so anything introduced high is carried further away from where it is wanted while anything introduced low stays in the band longer. That is not a claim about any product's performance; it is a property of tall rooms, and it points in the same direction as everything else on this page.
And a running-cost point I will make carefully, because SOSA does not publish consumption figures and I will not invent one. I cannot tell you what any of this costs to run, and nobody should give you a number, a range or a monthly figure - that conversation goes to WhatsApp. What I can tell you is the shape of the thing: a machine run harder to condition unoccupied air is doing work with no occupant at the other end of it, and it does that every trading hour for the length of the sales period. Placement is free. The dial is not.
One: low, not high. The most common instinct in a tall room is to put the unit up, because up is where the space is. Up is where the space nobody uses is. Position at or near the occupied band. If the unit is wall mounted, mount it low. If it is freestanding, let it stand. Do not put it on a mezzanine edge overlooking the entrance, which is the single most photogenic and least effective position in the building.
Two: inward, not at the door. The first several feet inside a cycling gallery entrance are effectively outdoor air, in every season. A unit placed there to create a threshold moment produces one of two outcomes: nothing perceptible, or a setting raised until the rest of the gallery is over-supplied in order to force something at the door. Place deeper in, in the zone where people actually slow down - typically the approach to the model, or wherever an executive first stops to talk. Accept that the threshold is unscented. That is not a failure, it is what a door does.
Three: out of the air conditioning supply airstream. If your gallery is air conditioned, find out where the supply grilles are and where the return is, and keep the unit out of the direct supply stream. Output dropped into a supply stream is carried away and thinned before it reaches anybody, and the invariable response is to raise the setting, which then produces a strong pocket somewhere near the return path and nothing where people stand. This is a question for whoever is responsible for the building's air, and their answer overrides anything on this page. If the gallery is ducted and you want the system to do the distribution deliberately rather than accidentally, that is what Aangan at ₹25,999 and Meenar at ₹38,500 are for.
Four: not in a dead corner. The opposite failure, and it produces a room that reads strongly beside the unit and not at all elsewhere, which gets diagnosed as insufficient output and treated with the dial. Some air movement past the unit is what distributes it. A corner with none is a pocket.
And if all four are satisfied and one machine still cannot hold the connected volume, add a second position rather than a bigger number. Two units in different parts of the same connected volume, both at the same low setting, give an evenness that one unit pushed hard never produces. That is the correct escalation, and it keeps the head-height level where you set it.
Two things to build into the fit-out while you can. A live socket at the chosen position - the Vaayu is mains powered at DC 12V / 1A and 5W and needs one - and a decision about the position itself, made on the drawing rather than by finding the nearest free plug after opening. A compromise position chosen for electrical convenience is how good installations become either invisible or overwhelming, and in a tall room the margin for that error is smaller than anywhere else.
- Get the true ceiling height, then compute each height zone separately and add them.
- Do the six-foot sum too, and write both numbers on the same sheet.
- Place low and inward, out of the entrance airstream and any supply airstream.
- If one unit will not hold it, add a second position at the same low setting.
Placement, register and the schedule that replaces the bigger number
Register matters less than placement in a tall room, and much less than the level, but there is one property worth choosing for here specifically.
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. In a large open volume with cycling doors, the registers that hold up best are the dry, unsweet ones, for a straightforward reason: in a big room at a low setting you are working with a thin signal, and a thin sweet or plush signal reads as a residue rather than as a character, whereas a thin dry one reads as the building.
Quiet Luxury is white tea, bergamot and cedar - hushed, polished and unsweet, and the one I would run given a single decision and nothing else known. It thins without collapsing, which is the property a tall room asks for. White Tea Serenity is white tea, aloe and cedar - clean, weightless and spa-like, and the register that most readily reads as clean rather than scented, which in a big new gallery of hard surfaces sits with what the room is already saying. Forest Suite is cedarwood, vetiver and green leaves, the driest of the three, and in a double-height space with timber, stone or a lot of daylight it is the one most likely to be received as a property of the architecture rather than a decision somebody made.
The ones I would keep out of a tall gallery. Lobby Bar is citrus, pepper and amber, bold and after-dark, and a big volume plus a bold register is the combination most likely to produce a room somebody remarks on. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush at a thin setting in a large room reads as leftover rather than as elegant. Warm Welcome is citrus, floral and sandalwood, a hotel-threshold register, which is a problem in a gallery precisely because a tall entrance already looks like a hotel threshold and doubling the signal is how a sales gallery stops reading as a place about homes. Tea Garden is jasmine, green tea and white tea and is the least risky floral in the collection, but a floral is the most likely thing to be named by a visitor, and in a room this size being named means being named loudly.
I will not rank the seven against each other on measured throw or longevity, and I want to be especially clear about that on this page, because a tall room is exactly where somebody will ask which one "carries further". SOSA does not publish that comparison and I am not going to improvise one. The variables that dominate in a double-height gallery are volume, connection, ceiling height, door cycling, supply airstreams and placement - all of them yours, none of them the blend's.
And there is no heritage, traditional, attar, oudh or rose-water register in the SOSA commercial range. The machines run the seven Hotel Collection registers and nothing else; the reeds are five scents of their own. Bespoke composition is a real SOSA service, discussed on WhatsApp rather than priced on a page - and it will not solve a tall room, because a tall room is a placement problem. One of the seven held at one written level already is a signature, because consistency makes a signature and uniqueness does not.
| Scent | Why it suits the mood |
|---|---|
| Raise the output · the instinct, and the wrong move | Supplies the whole volume including the fourteen feet nobody breathes, so the occupied band only rises by over-supplying everything. Result: head height higher than anyone would have chosen, your own staff receiving it for eight to ten hours a day, and the threshold still reading as thin because the threshold is diluted by cycling doors rather than by height. |
| Place low and inward · the correction, and it is free | Puts the source in the band people occupy. 800 sq ft at 6 ft is 4,800 cubic feet, about 136 cubic metres, against a full-height 453; at 1,500 sq ft it is 9,000 cubic feet, about 255, against 850. Deeper into the room than the entrance, because the first few feet inside a cycling door are effectively outdoor air in every season. |
| Move out of the airstreams · the fix nobody checks | Output dropped into an air conditioning supply stream is carried away and thinned before it reaches anybody, and the usual response is to raise the setting, producing a pocket near the return and nothing where people stand. A dead corner is the opposite failure: strong beside the unit, absent four metres away. Where the grilles are is a question for whoever runs the building's air. |
| Add a second position · the correct escalation | If a correctly placed unit still cannot hold a large connected volume, two units in different parts of that volume at the same low setting give evenness that one unit pushed hard never produces. Where the gallery runs on ducted air conditioning, Aangan at Rs 25,999 and Meenar at Rs 38,500 distribute through the system the building already has, which is a decision for the people responsible for it. |
So the buying answer for a tall gallery. 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 in a city with two damp stretches rather than one, and never a claim to control humidity or treat a building. 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 - and a 1,500 sq ft double-height entrance at about 850 cubic metres is one of the few rooms in this bank that genuinely approaches that. Bluetooth app and timer, 400ml tank, freestanding or wall and HVAC mount, DC 12V / 1A at 5W so it needs a live socket, CE, RoHS and SGS. Ask the contractor for a socket at the chosen low, inward position while the drawings are still open; retrofitting it means a chased wall or a compromise position near the nearest free plug, and a compromise position is what this entire page is written against.
If your gallery runs on ducted air conditioning and you would rather the system did the distribution deliberately, the ducted machines are 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. That is a decision for the people responsible for the building's air and nothing here is HVAC advice.
For a small doored room off the gallery - an office, a reception, a single enclosed space - an ultrasonic is usually the whole purchase: a SOSA Boond at ₹899 or a SOSA Sukoon at ₹1,899, running the water-based Hotel Collection from ₹299, with 100ml refills at ₹999 and 300ml also available; the pack of seven 15ml bottles at ₹1,799 is how to audition registers in your own air. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine - the two systems are not interchangeable. And the SOSA reed diffusers are their own registers with no plug and nothing to switch off - Mountain Breeze ₹849 the driest, plus Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799 and Fresh Brew ₹849, 130ml from ₹1,249, about 6 to 10 weeks. A reed is passive and local and will do nothing whatsoever in a double-height volume, which is worth stating so nobody tries it.
To go deeper: the room-by-room levels for the rest of the building are in whether the model, sample apartment and negotiation room should have different scent intensities. The strategic case for scenting a gallery at all is in whether a premium Lucknow developer should have a signature scent in its sales gallery. And nothing gets switched on until the question in whether new paint, laminate and adhesive odours should be ventilated out before fragrancing a sample flat has been answered honestly.

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.
