Six things get designed in, and every one of them is a line on a drawing rather than a purchase. A live socket in the right place, because the SOSA Vaayu at ₹11,999 is DC 12V / 1A, 5W and mains powered - it is not a battery unit and it does not run on goodwill. A mount point if it is going on a wall rather than standing free. Its position relative to the entrance airstream, because a unit near a door that cycles all day is scenting the car park. Its position relative to supply and return grilles, because output dropped into a supply stream gets carried away and thinned before it reaches the room, and output dropped in front of a return gets taken out of the room entirely. Which rooms have doors that actually close, because that is what decides how many separate volumes the gallery has, and therefore how many units and how many settings you are talking about. And the rule that a unit is never ducted into air handling that serves somebody else's premises.
All of that costs almost nothing while the drawings are open. Every one of those six becomes expensive, ugly or impossible once the gallery is built: a chased wall, a visible trunking run, a floor box in the wrong place, or - by far the commonest outcome - a unit standing wherever the nearest free socket happens to be, which is almost always behind the reception desk or immediately inside the entrance, the two worst positions in the building.
But the purchase and the calibration still happen last, and I am going to be firm about that. You cannot judge a level in a site that is still off-gassing. A new sales gallery is paint, adhesive, laminate, sealant, new carpet, new upholstery and new joinery, all putting their own smell into the room for a period after the work finishes, and fragrance adds scent - it has never once removed any. Run a register into a gallery that is still announcing its own fit-out and you get both at once, which most people find worse than either, and you will have taught yourself to dislike a blend that was never the problem.
Two limits before I earn the rest of the page. I will not tell you that a scent sells anything, and a sales gallery is where that temptation is at its highest: no claim here about a buyer, a site visit, an enquiry or a booking. The honest ceiling on ambient scent is improved evaluations of a space and its service, longer dwell and stronger recall of a space, at moderate effect sizes. And nothing on this page is HVAC, electrical, fire or building advice. Your consultant, your electrician and the people responsible for the building's air decide what goes into it, and their decision overrides every line here.
Should the diffuser be ducted into the building's air handling? Only if the air handling serves your premises and only if the people responsible for that system say yes, in writing, at design stage. The Vaayu can wall-mount or HVAC-mount, and the ducted machines proper are the Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and the Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft. What you never do is put fragrance into a system that also serves somebody else - another tenant, a shared lobby, a neighbouring unit, a building common area. That is not a fragrance question, it is a courtesy and a building-management question, and the answer to it belongs to the building rather than to you. And you never reduce ventilation or close down air exchange so a fragrance holds longer. Never.
Should I buy the machine during the fit-out? You can, but do not switch it on, and do not let anybody set a level on a building site. The mistake is not the purchase, it is the calibration. Standing in a half-finished gallery you are calibrating against dust, cut timber, solvent and fresh paint, in a room with no furniture, no soft goods and no people in it - and a level that reads as modest in that room is loud in the finished gallery on an ordinary Wednesday. Fit the socket, leave the box shut, let the fit-out stop smelling of itself, and then set the level using somebody who has been outside for ten minutes and does not work for you. Every over-scented commercial space I have ever been sent a photograph of was set during or immediately after a fit-out, by a sincere person in an empty room.
Then the airstreams, which is the part of placement that is invisible on a plan and decides more than anything else. Two different things are going on. A supply grille is pushing conditioned air into the room, and a unit sitting directly in that stream has its output picked up, carried across the space and thinned out before it ever meets a person; owners then conclude the machine is underpowered. A return grille is pulling room air out, and a unit in front of one is scenting the plenum rather than the gallery. What you want is the room's ordinary circulation - the air that people are actually standing in - without the blast and without the extraction. That is a conversation with whoever is designing the air, it takes about four minutes, and it is free in month two of a project and impossible in month ten. In Lucknow there is a seasonal edge to it as well: a gallery in a 39.9 degrees C May has the air conditioning working hard and the air moving fast, and the same gallery in a January whose days reach only about 21.4 degrees C, with fog common through December and January, is a very different room with a very different amount of movement in it. Same position, different behaviour - which is an argument for one designed position and several written settings, not for moving the machine about.
Then the doors, which is the cheapest and most valuable drawing exercise of the lot. Take the general arrangement, a highlighter, and mark every door that will genuinely be shut during a viewing appointment: the negotiation room, the private closing room, the manager's office, the sample apartment's bedrooms, the store. A coverage rating assumes one connected body of air, and scent does not travel through a closed door. So each of those doors is not a detail, it is a boundary that turns one scenting problem into several. Do that exercise and the whole brief changes shape: you usually discover that the connected gallery volume is smaller than you assumed, that two or three rooms are separate volumes that should get nothing at all, and that the number of machines you actually need is one. The arithmetic is worth doing by hand on the plan in front of you: a 2,000 sq ft gallery at a 12 ft ceiling is 24,000 cubic feet, which divided by 35.3 is about 680 cubic metres; a 1,200 sq ft gallery at 12 ft is 14,400 cubic feet, about 408 cubic metres. Against the Vaayu's published approximately 1000 cubic metres of connected air, most galleries are comfortably inside one machine.
Then the one line that is not about performance at all. Write on the drawing that the unit is not to be ducted into air handling serving premises that are not yours. A sales gallery is very often a tenanted unit, a podium space, a temporary structure on site or a floor in a building with other occupiers, and putting a fragrance into a shared system means putting it into somebody else's air without asking them. That is not a technical objection, it is a straightforward one, and it is the sort of thing that gets decided by default at 6pm on a Thursday by a contractor who is trying to be helpful. Decide it in writing at design stage instead. Where ducting is genuinely appropriate - your own system, serving your own premises, agreed by the people responsible for it - the ducted machines are the Aangan at ₹25,999 and the Meenar at ₹38,500. And in no version of this, ever, do you reduce ventilation or close down air exchange so that a fragrance holds longer.
And then you stop, because the rest is not a design-stage decision. Do not buy on the strength of a mood board and do not set a level in an empty room. A finished sales gallery is off-gassing - paint, adhesive, laminate, sealant, carpet, foam, upholstery, new joinery - and that is a source, not something a fragrance addresses. Fragrance adds scent; it does not remove, neutralise, absorb, deodorise, dry or purify anything, and no SOSA product treats, filters, dries, dehumidifies or purifies air. So the sequence is source, then ventilation, then cleaning, then fragrance, and the gallery has to get through the first three before the fourth is even a sensible conversation. I will not give you a number of days for that and neither should anybody else, because it depends on which materials went in, how much air the space gets and how warm it is. Judge it by nose first thing in the morning, before staff, before the air conditioning has run, when the room has had all night to accumulate and nobody has disturbed it. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, do the door exercise. Print the general arrangement, take a highlighter, and mark every door that will genuinely be shut while a buyer is in the building. Then write a number beside each enclosed space: floor area multiplied by ceiling height gives cubic feet, cubic feet divided by 35.3 gives cubic metres. That single sheet answers more questions than any conversation with a supplier will, because it tells you how many volumes you have, which is the only question that determines how many machines you need.
Here is what the sheet usually shows in a sales gallery. The main gallery floor is one connected volume and it is the only one that matters. The negotiation room is a separate volume, small and long-dwell - 180 sq ft at a 10 ft ceiling is 1,800 cubic feet, about 51 cubic metres - and it takes the least of anything in the building, or nothing. The sample apartment, if it is a doored suite off the gallery, is its own volume again and should be treated as a home rather than as more gallery. The stores and back-of-house get nothing. And the double-height entrance, if you have one, is a very large volume that people cross in ninety seconds and occupy only in the bottom six feet.
Second thing worth doing at design stage, and it has nothing to do with fragrance: get the ventilation and extraction specified properly and commissioned properly. That is the layer underneath everything on this page. If the finished gallery has a source - a drain, a damp reveal, a kitchenette, a store that holds solvents - no machine and no setting is going to help, and the fit-out is the only cheap opportunity you will ever get to deal with it. I am in the fragrance business and I am telling you to spend the money on air first, because the alternative is spending it on fragrance twice.
And one standing arrangement to write into the operations pack before the gallery opens, not after somebody complains. Anyone on the sales team can switch a named unit off without asking a manager. Your sales staff stand in that air eight to ten hours a day, which is many times the exposure of any visitor, and adaptation means they are simultaneously the most exposed people in the building and the least reliable judges of the level. A reported reaction is a recalibration signal, not a tolerance problem. No health or allergy claim is made here in either direction.
What actually goes on the drawing set, and what has to wait until the gallery is finished
Three things decide whether design-stage planning pays off: the electrical and the mount, the airstreams, and the door plan. The first is a line item, the second is a four-minute conversation with the services consultant, and the third is a highlighter on a printed plan. None of them is a purchase, and none of them commits you to buying anything.
Do the arithmetic on the drawing rather than in the showroom, because design stage is exactly when people buy the wrong size. A sales gallery of 2,000 sq ft at a 12 ft ceiling is 24,000 cubic feet, and 24,000 divided by 35.3 is about 680 cubic metres. A smaller gallery at 1,200 sq ft and 12 ft is 14,400 cubic feet, about 408 cubic metres. A larger one at 3,000 sq ft and 12 ft is 36,000 cubic feet, about 1,020 cubic metres, which is the first case in this block that actually reaches the Vaayu's published approximately 1000 cubic metres of connected air. And a double-height entrance at 800 sq ft and 20 ft is 16,000 cubic feet, about 453 cubic metres on its own.
Which produces the finding that runs through this entire bank: the machine is almost never the constraint. The setting is. A typical Lucknow sales gallery sits at half or two-thirds of what one Vaayu is rated for, and the failure mode is therefore never insufficient output - it is a level chosen for a doorway rather than for a family who will be in that room for an hour, or a level chosen by somebody whose nose stopped reporting accurately in week three.
Keep the word connected in front of you the whole time. A coverage rating assumes one connected body of air. A closing door ends a volume. An open stair or a removed partition joins two volumes and doubles the air one unit is being asked to hold, which is a thing that happens on sales gallery drawings constantly, because galleries love a void. And if the entrance is a wide opening onto a site road or a podium, the first few feet of the gallery are effectively outdoor air, which is a reason to place deeper into the room and to expect nothing at the threshold - never a reason to seal anything up.
Finally, design for the year rather than for the day of handover. Lucknow gives a sales gallery more seasonal range than almost any city I write about: April and May are hot and genuinely dry, with mean daily maxima near 38.2 and 39.9 degrees C and the year's humidity trough falling in those same hottest months; July and August are the wet ones, with roughly 238 and 242 mm of rain; and from late November to February the city is genuinely cold and damp, January minima near 7.8 degrees C, January days reaching only about 21.4 degrees C, a record low of minus 1.0 degrees C, and fog common through December and January. Two damp stretches, not one, separated by a hot dry spring. That is an argument for one designed position and three written settings, which is exactly the kind of thing a Bluetooth timer is for.
The socket. The Vaayu at ₹11,999 is mains powered at DC 12V / 1A and 5W. It draws almost nothing, which is precisely why nobody thinks about it - but almost nothing is not nothing, and it still needs a live outlet at the position where the unit is going to stand or hang. Mark the unit on the plan first, then mark the socket at it. Do it in that order. If you mark the sockets first and the unit afterwards, the unit ends up serving the sockets, which is how a machine finishes up behind a reception desk facing a wall.
The mount point. The Vaayu lays flat and stands free, or it mounts to a wall or into HVAC. If the intention is a wall, the height and the fixing are a drawing decision: high enough that it is out of reach and out of casual sight, clear of anywhere a person would lean or set something down, and not directly above a seat. There is a behavioural reason as well as an aesthetic one. A unit that anybody can reach is a unit that somebody will adjust, and in a sales gallery that somebody is usually a well-meaning person on a slow afternoon who thinks it seems weak - which it will, to them, because they have been standing in it since ten o'clock.
What a free-standing unit needs instead. If it is staying loose, it still needs a designed home: a shelf, a plinth, a console, a spot in the joinery. Not a floor beside a sofa where it gets kicked, and not a windowsill. The reason to draw it rather than decide it later is that a sales gallery's joinery is usually bespoke, so the shelf you want is free at drawing stage and is a carpenter's callout afterwards.
And while the electrician is still a person you can talk to, ask for one more thing. If the gallery has a negotiation room or a sample apartment with its own door, and there is any chance you will want a small unit in one of them later, get a socket in the right place there as well. An ₹1,899 Sukoon also needs mains. You are not committing to buying anything by having a socket in a sensible place; you are simply refusing to let a cable route decide your scenting strategy in eighteen months.
None of this is electrical advice and none of it overrides your electrician. It is a list of questions to put in front of them early, while the answer is still a pencil line.
The entrance. A sales gallery door cycles constantly: a family arriving, a broker leaving, a site engineer crossing, a delivery. Every cycle exchanges the air in the first few feet of the room with whatever is outside, and in Lucknow whatever is outside is a 39.9 degrees C dry May afternoon, a wet August, or a foggy January morning. A unit placed near that door is scenting the exchange rather than the room, which feels intuitively right - the buyer arrives, the buyer meets the scent - and is mechanically wrong. Place deeper. Accept that the threshold will read as neutral, because it genuinely is. If your entrance is a wide opening onto a podium or a site road, treat the first stretch of the gallery as outdoor air and design for the part of the room where people actually stop and stand.
The supply grille. Conditioned air coming into a room is moving fast and going somewhere. Output introduced directly into that stream gets picked up, carried and diluted before it reaches anybody, and the symptom is an owner who concludes the machine is too small for the space. It is not too small. It is in the blast. Ask for the supply layout at design stage, and place the unit in the room's ordinary circulation instead - the slower air that people are actually standing in.
The return grille. The opposite error and less well known. Air being pulled out of the room takes fragrance with it. A unit sitting in front of a return is doing a very efficient job of scenting a duct. On a drawing this is trivially avoidable; in a finished gallery it means moving a socket.
What you are aiming for. Not a corner, because a dead corner never joins the room's air at all. Not the blast, not the extraction, not the doorway. The position you want is in the normal, gentle circulation of the part of the room where people stand for more than a moment - which in most galleries is somewhere around the model, the seating, or the route between the two.
The seasonal footnote, which is real here rather than decorative. The same position behaves differently across a Lucknow year, because the building behaves differently. In April and May the air conditioning is working hard against mean daily maxima near 38.2 and 39.9 degrees C, in a season that is genuinely dry - the year's humidity trough falls in exactly those hottest months. In July and August the city is wet, with roughly 238 and 242 mm of rain. And from late November to February it is cold and damp, with January days reaching only about 21.4 degrees C, minima near 7.8, and fog common through December and January. You do not solve that by moving the machine four times a year. You solve it with one designed position and three written settings, which is what the Bluetooth app and timer are actually for. And you never, in any season, reduce ventilation or close down air exchange so a fragrance lasts longer. Not in a closed-up January, not in a wet August, not ever.
The shared-air rule, and I want it written on the drawing rather than agreed in a corridor. A unit is never ducted into air handling that serves premises other than your own. Sales galleries are frequently tenanted units, podium spaces, temporary structures or floors in buildings with other occupiers, and a fragrance introduced into a shared system is a fragrance introduced into other people's air without their agreement. The Vaayu can HVAC-mount and the ducted machines are the Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and the Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - and every one of those installations is a decision for the people responsible for that system, not for a fragrance supplier and not for the person who happens to be on site when the contractor asks. Get it in writing early. Nothing here is HVAC or building advice.
And now the part where design stage ends. You have the socket, the mount, the position and the door plan. You do not yet have a level, and you should not try to get one. Here is the mechanism, because it is the part of this page worth keeping. A fit-out is off-gassing: paint, adhesive, sealant, laminate, new carpet, foam, upholstery and new joinery all release their own smell for a period after installation. That is a source. Fragrance adds scent - it does not remove, neutralise, absorb, deodorise, dry or purify anything, and no SOSA product treats, filters, dries, dehumidifies or purifies air, not the Vaayu, not an ₹899 Boond, not a ₹749 reed. Run a register into a gallery that is still off-gassing and you get the fit-out and the register layered together.
The second reason to wait is calibration, and it is the bigger one. Your nose calibrates against whatever it has been sitting in. During a fit-out it has been sitting in solvent, dust and cut timber, in a room with no furniture, no soft goods and no people. Into that baseline a fragrance has to work hard to register at all, so you set it where it registers - and then the gallery fills up with joinery, upholstery, carpet, brochures, staff and visitors, and the same setting reads considerably louder. An empty hard room and a furnished working room are not the same space.
The test, and why it is a morning test. Come in first thing, before staff, before anyone opens anything, before the air conditioning has run. The room has had all night to accumulate and nobody has disturbed it, which makes it the most honest reading you will ever get. Stand three steps inside the door for sixty seconds. If what you meet is paint, adhesive, laminate or new carpet, you are not ready: ventilate more - more air, never less - and come back on another morning. I will not give you a number of days and nor should anyone, because it depends on materials, air exchange and temperature, and in Lucknow that last variable swings from a 39.9 degrees C May to a January day that reaches about 21.4.
- Mark the unit position first, then a live socket at it - Vaayu is DC 12V / 1A, 5W mains.
- Keep it out of the entrance airstream and clear of supply and return grilles.
- Highlight every door that closes - each one ends a volume and starts another.
- Write the no-shared-ducting rule down; set the level only once the gallery trades.
Which register, what level, and why calibration is deliberately the last thing that happens
Assume the gallery is finished, the fit-out has stopped announcing itself and the morning test reads as a room rather than as a building site. Only now does any of the following matter, and it matters less than the level.
The volume first. Use the door plan you marked up at design stage. The connected gallery floor is what you are scenting. The negotiation room - 180 sq ft at a 10 ft ceiling, 1,800 cubic feet, about 51 cubic metres - takes the least of anything or nothing, because it is a small enclosed volume holding a few people for a long time and it is where the most sustained conversation in the building happens. A sample apartment behind its own door is a separate brief and a separate page. Stores, back-of-house and anywhere brochures and print are kept get nothing.
Then the level, which is the only variable that really matters. Set it for the family who will be in that gallery for an hour, not for the person who walks through in ninety seconds, and set it with somebody who has been outside for at least ten minutes and does not work for you. Ask 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 set too high. Not unpleasant, not wrong: too high for this brief. And write the setting down the day it is right - the unit, the register, the exact setting, the hours - because a level in a commercial space drifts upward over months, adjusted in good faith by people who have adapted to it.
Then the register, which matters far less. 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. Quiet Luxury is white tea, bergamot and cedar - hushed, polished and unsweet, and what I would run in a sales gallery given one decision and no further information. 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 as scented, which suits a bright, hard-surfaced, recently finished room. Forest Suite is cedarwood, vetiver and green leaves - the driest of the three and the one that reads as part of the building rather than as a decision, which is useful where the gallery is doing timber, stone and a lot of material sampling.
What I would keep out of a sales gallery. Lobby Bar is citrus, pepper and amber, bold and after-dark; turning a theatrical register down gives you a quiet theatrical register rather than an inconspicuous one. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush accumulates across a long appointment in a way that dry does not. Warm Welcome is citrus, floral and sandalwood, a genuine hotel-threshold register, and the instinct a sales gallery encourages is exactly the instinct to resist, because a gallery already has enough hospitality signalling in it. Tea Garden is jasmine, green tea and white tea and is the least risky floral in the collection, but a floral of any weight in a room where people handle samples, finishes and fabric boards is a decision somebody will notice. 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 belong to your building.
And if what you had in mind was something traditionally Indian, an attar or a rose direction for a Lucknow project: there is no such register in the commercial range. The machines run the seven Hotel Collection registers and nothing else. Bespoke composition is a real SOSA service, discussed on WhatsApp rather than priced on a page - but the cheaper honest answer comes first, and it is that one of the seven held at the same level every day already is a signature, because consistency makes a signature and uniqueness does not.
One standing arrangement, written into the gallery operations pack rather than remembered. Anyone on the sales team can switch a named unit off without asking a manager. They are in that air eight to ten hours a day, many times the exposure of any visitor, and a reported reaction is a recalibration signal rather than a tolerance problem. No health or allergy claim is made in either direction.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · the default for a gallery floor | White tea, bergamot and cedar. Hushed, polished and unsweet, and what I would choose with one decision and no information about the building. It carries a small amount of presence across a connected gallery floor without becoming the thing a family thinks about during a sixty-minute appointment, which is the correct test for a room people sit in rather than cross. |
| White Tea Serenity · a bright, hard-surfaced new fit-out | White tea, aloe and cedar. Clean, weightless and spa-like, the register that reads as clean rather than as scented. It sits with a newly finished gallery of glass, stone and pale joinery instead of adding a second idea on top of it. Set the level for minute forty, not for the doorway. |
| Forest Suite · timber, stone and a material-heavy gallery | Cedarwood, vetiver and green leaves. The driest of the shortlist and the one that reads as structural rather than decorative, so it is received as a property of the building rather than a choice somebody made. Useful where the materials themselves are part of the pitch. |
| Nothing, and not yet · the negotiation room, the stores, and the whole gallery until the morning test passes | Not a lower setting - nothing at all. The negotiation room is a small enclosed volume holding a few people for a long time, about 51 cubic metres at 180 sq ft and a 10 ft ceiling, and it takes the least of anything or none of it. Stores and back-of-house get nothing. And the entire gallery gets nothing while the fit-out is still off-gassing, because fragrance adds scent rather than removing it and a register on top gives you both. |
So the buying answer, and note where it sits in the sequence: after the gallery is finished, not during.
For one enclosed room - a manager's office, a doored viewing room, a reception nook with its own volume - an ultrasonic is usually the whole purchase: a SOSA Boond at ₹899, 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. The pack of seven 15ml bottles at ₹1,799 is the sensible way to audition registers in your own finished air rather than from a description, and judge each on day five rather than the first afternoon.
For the connected gallery floor the commercial answer is the SOSA Vaayu at ₹11,999: waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue - which in a city with two damp stretches a year is a plain design preference worth stating, and never a claim to control humidity or treat a building. Approximately 1000 cubic metres of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. Bluetooth app and timer, 400ml tank, freestanding or wall and HVAC mount, DC 12V / 1A at 5W so it needs that designed socket, CE, RoHS and SGS. The app is most of the value at design stage, for a reason that has nothing to do with convenience: it is what lets you write a setting down and keep it, running gallery hours only, with one setting for a dry May, one for a wet August and one for a foggy January. The two systems are not interchangeable - the ultrasonics are water-based cool-mist machines, while the Vaayu and the ducted Aangan at ₹25,999 and Meenar at ₹38,500 run waterless nebulising oil. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine.
If you want no plug, no noise and nothing to switch off - genuinely useful in a temporary structure or a gallery with a difficult power layout - 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. 130ml from ₹1,249, lasting about 6 to 10 weeks. A reed is passive and local: it scents the few feet around it and will not fill a gallery, which on a reception desk is sometimes exactly the point.
To go deeper: the sample apartment is a different brief from the gallery and the distinction is worth getting right, so read whether a sample apartment should smell more residential than the corporate sales lounge. If you run more than one project, the portfolio question - one register, separately calibrated levels, written down per gallery - is in can one signature scent connect multiple projects under the same developer brand. And if you want all of this to survive the next project rather than being re-decided each time, putting scenting into a standing sales-experience specification is the page that closes this block.
What SOSA does not publish and this page will therefore not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time - and no number of days for a fit-out to settle.

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.

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.
