That last clause is the trap. The place where an automatic door has its largest effect is the first few metres of the store, and the first few metres of the store is where an owner walks in, pauses, decides the scent is not coming through, and turns it up. It was coming through perfectly well six metres further in, at the seating group, where the person who actually matters is sitting for ninety minutes. The doorway is the reading that lies to you, and an automatic door makes it lie harder.
So this page is about the mechanism first and the remedy second, because the remedy is short. The remedy is placement and depth. Move the unit out of the door's airstream, use the depth of the store so the back holds what the front cannot, and accept a gradient from the threshold inward. What is not a remedy: a bigger setting, a bigger machine, or - and I want to be completely unambiguous about this - anything at all done to the door. An automatic door's opening width, hold-open time and closing speed are an accessibility and life-safety specification. They are not a fragrance dial, and no page of mine is going to suggest touching them.
One honest framing before the arithmetic. Nothing here is a fault report on your machine. A store with a busy automatic door that seems to lose its fragrance is not broken; it is behaving exactly as the physics say it should, and the correct response is to plan around it rather than to compensate for it.
Should I change the door timing so the fragrance lasts longer? No. An automatic door's detection range, opening width, hold-open time and closing speed are set as an accessibility and safety specification, and they are not a scenting adjustment. The same applies to propping it, disabling a sensor or reducing any ventilation so that fragrance lingers - none of that is advice this page will give in any phrasing. Ventilation and safe access win; you solve the scenting problem with where the unit stands, how big the connected volume is, and what level you run.
Where should the diffuser go in a showroom with an automatic door? Well inside, out of the airstream, and not facing the aperture. As a working rule, put it past the first line of cases, on the far side of any obstruction from the door, away from supply diffusers and return grilles so it is not being fed straight into the extract, and near the part of the store where people actually sit. Ordinary retail prudence applies too: not above or beside the watchmaker's bench, open display trays or stock storage. A SOSA Vaayu at ₹11,999 mounts freestanding, on a wall or into HVAC, which gives you options the socket by the door does not.
Assume a common enough showroom entrance: a sliding aperture about 6 ft wide and 8 ft high, which is 48 square feet of hole when it is fully open. Assume a cycle that is roughly nine seconds from the moment the door starts to move to the moment it is shut again - two seconds opening, four or five seconds of hold-open while somebody actually walks through, and three seconds closing. Now count cycles rather than customers, because those are different numbers and the difference is the point. Two hundred cycles across a ten-hour trading day is 200 multiplied by 9, which is 1,800 seconds. That is thirty minutes a day in which your shopfront has a 48 square foot hole in it.
Thirty minutes out of a ten-hour day is 600 minutes, so the aperture is open about 5 per cent of trading hours. Multiply 48 square feet by 5 per cent and you get an equivalent continuous opening of roughly 2.4 square feet - a permanent hole about the size of a large window fanlight, sitting in the wall all day. That is not nothing, and it is also not a catastrophe. It is a number you can plan around, which is exactly what this page is asking you to do.
Now put it against your volume. A 700 sq ft showroom at a 12 ft ceiling is 700 multiplied by 12, which is 8,400 cubic feet, and 8,400 divided by 35.3 is about 238 cubic metres. A 1,000 sq ft floor at 12 ft is 12,000 cubic feet, about 340 cubic metres. The exchange through the door is a meaningful fraction of a small store's air over a day and a small fraction of a large one's, which is why two showrooms with identical doors and identical machines can report completely different experiences.
Two things make the real effect larger than the raw aperture arithmetic suggests. The first is that air does not sit still and wait to be swapped; it moves through the opening under whatever pressure difference exists at that moment, and in a mall tenancy that difference is set by the mall's air handling rather than yours. The second is the human being. A person walking through a doorway drags a wake of air behind them and pushes a slug of air ahead of them, and every person who comes through carries a little of the concourse in and a little of your store out. On a Saturday evening in a mall that is a continuous procession.
And one thing makes the effect smaller than owners assume, which is worth saying because it changes where you put the machine. All of this happens at the front. Air exchange through an aperture is a local phenomenon that decays with distance, and six metres into a store, behind a case line, in the corner where the seating group is, the door might as well be in a different building. That is the whole strategy in one sentence: you cannot hold the threshold, so stop trying to, and hold the part of the store where somebody sits for ninety minutes instead.
What you do not do, in any phrasing and for any reason, is alter the door. Detection range, opening width, hold-open time and closing speed are set for accessibility and safety, which includes people with mobility aids, people carrying things and people who do not move at the speed an able-bodied adult does. Nor do you prop it, disable a sensor, or reduce ventilation or extraction anywhere in the building so that fragrance lingers. Ventilation wins. A well-ventilated store is genuinely harder to scent, and that is a trade-off to accept rather than a problem to engineer around. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Here is a diagnostic I would run before you spend anything, because it takes one day and no money. Get somebody to count door cycles for a full trading day with a tally on a sheet at the till. Not customers - cycles. In a mall-facing showroom those two numbers can differ by a factor of three, because an automatic door with a sensor pointed at a concourse opens for everybody who walks close enough to it: people passing, people stopping to look at the window, a child running past, the security guard doing his round. Every one of those is a full air exchange on your account, and none of them is a client.
That count also tells you something a supplier cannot. Two hundred cycles a day and 238 cubic metres of store is a different situation from six hundred cycles a day and the same volume, and it is the sort of fact you should hand to anybody sizing your scenting. On WhatsApp it is more useful than the square footage.
The second thing worth measuring costs nothing either: find out which way the air actually goes. Hold a light tissue or a thread at the threshold at three different times of day - first thing, midday, and the evening peak. If it blows inward, the concourse is being pushed into your store and the mall's own air is part of yours. If it blows outward, you are losing your air to the concourse. Both happen, often in the same shop on the same day, because the pressure balance changes with the building's plant, the weather and the traffic. Knowing which one you have is the difference between a sensible placement and a guess.
And do not judge the result by standing in the doorway. I have lost count of the number of owners who walked into their own store, stopped two metres in, said "I can't smell anything", and turned the machine up. Of course they could not. They were standing in the one part of the building that is being flushed two hundred times a day, having just come in from outside with a nose full of street or concourse. Walk to the chair, sit in it for ten minutes, and then form a view. Better still, sit in it for forty-five, because that is the reading the level is supposed to be set to.
Your sales team is the other instrument. They stand in that air eight to ten hours a day at closer range to the unit than any client, and their door is the same door. If somebody on the floor says it has become noticeable, turn it down first and discuss it second. And a client who says they react to fragrance gets the unit switched off for their appointment by whoever is on the floor, without finding a manager first. That is a standing arrangement, not a favour.
One door cycle is one air exchange, and the arithmetic of two hundred of them
There are three things worth understanding about an automatic door in a scenting context, and only the third one is actionable - which is the correct ratio, because the first two are what stop you from doing something expensive or unsafe.
The first is the mechanism: what a cycle actually is, why two hundred of them matter, and why counting cycles rather than customers changes the number. The second is the boundary of what you are allowed to touch, which is narrower than owners expect and includes nothing about the door itself. The third is placement, which is where the entire remedy lives and which is also, in my experience, the single most commonly botched decision in commercial scenting - not because it is hard, but because the machine gets put wherever the free socket was during fit-out, and in a retail unit the free socket is very often near the entrance.
It is worth naming what sort of rooms we are talking about. Watch showrooms are commonly 10 to 14 feet to the ceiling, with a mall flagship or a heritage store reaching 16 to 20. They are made of glass, stone, metal and lacquer, which absorb almost nothing, so more of what you add stays audible in the air than in a carpeted room of the same size. And they have the longest customer sit in retail: an hour, an hour and a half, sometimes more, at a tray, under a light, with a loupe. Those three facts together are why the answer to a busy door is never "add more". A store with hard surfaces holding a client for ninety minutes is a room that wants a low, even level in its depth, and a doorway that reads as nearly nothing.
Do the arithmetic by hand as you read, because it takes ten seconds and it changes what you buy. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A 400 sq ft showroom at 12 ft is 4,800 cubic feet, about 136 cubic metres. A 600 sq ft floor at 12 ft is 7,200 cubic feet, about 204 cubic metres. A 900 sq ft floor at 12 ft is 10,800 cubic feet, about 306 cubic metres. A 1,500 sq ft flagship at 14 ft is 21,000 cubic feet, about 595 cubic metres. All of those sit inside the SOSA Vaayu rating of approximately 1000 cubic metres of connected air at ₹11,999 - and the headroom is not permission to run it hot. It is the reason a showroom with a busy door can still run a low setting and be even where it matters.
Three separate things happen in those seconds and they add up. First, the aperture itself. While the door is open, air crosses the opening in whichever direction the pressure difference points. In a mall tenancy you do not set that difference; the mall's air handling does, along with the weather, the concourse doors and how many other tenants have their own systems running. Sometimes the concourse is being pushed into you and sometimes your store is being drawn out. Both are exchanges, and both dilute what you have added.
Second, the person. A human body moving through a doorway pushes a slug of air ahead of it and drags a wake behind it. It is a small volume per person and it is not small across a Saturday. This is also why a door that opens and immediately has three people walk through it exchanges more than a door that opens for one.
Third, the door leaf itself. A sliding or swinging leaf moves air as it travels - a modest piston effect that is more noticeable on a swing door in a tight lobby than on a wide slider, but it is there, and it happens twice per cycle.
Now the arithmetic, with the assumptions on the table so you can substitute your own. Take a 6 ft by 8 ft aperture: 48 square feet. Take a nine-second cycle. Two hundred cycles gives 1,800 seconds, which is thirty minutes of a ten-hour day, or 600 minutes. Thirty divided by 600 is 5 per cent. Multiply 48 by 0.05 and you have an equivalent continuous aperture of about 2.4 square feet. Four hundred cycles doubles it to about 4.8 square feet. Six hundred cycles takes it to roughly 7.2 square feet, which is a permanent doorway-sized hole about two feet by three and a half, standing open all day.
Set that against the alternative, which is what makes the finding useful rather than alarming. A fully open mall storefront with no door at all might be 20 feet wide and 10 feet high, which is 200 square feet of permanent aperture, 100 per cent of the day. Against that, an automatic door at two hundred cycles is roughly one per cent of the exchange, and even at six hundred cycles it is a small fraction. An automatic door is a much better problem to have than an open front. If you have a door at all, you are in the easier half of this bank.
Which is why counting cycles matters. Customers are not cycles. A sensor aimed across a mall concourse fires for people who are walking past, stopping to look, turning around, or standing outside on the phone. In a busy centre a showroom can log three or four cycles for every person who comes in, and every one of them is an exchange charged to your account. Put a tally sheet at the till for one trading day. It is the most useful number you will generate this month and it costs nothing.
One more honest note about what the numbers can and cannot tell you. This is a worked illustration to give you a sense of scale, not a measurement of your building. Real airflow through a doorway depends on the pressure difference, the temperature difference, the wind outside, the geometry of your lobby and how people actually move. What the arithmetic settles is the shape of the answer - front is lost, depth is held - and that shape is stable even when the exact figures are not.
An automatic door has a set of parameters: detection range, opening speed, opening width, hold-open time, closing speed, and the behaviour of its safety sensors. Those numbers are not comfort settings. They exist so that a person with a walking frame can cross the threshold before the door begins to close, so that a wheelchair user is detected at the right distance, so that somebody carrying a box with both hands is seen, so that a child is not caught, and so that the door behaves correctly in the event of a power failure or an alarm. They are set by whoever commissioned the door against the relevant standard and the building's own requirements.
So: no scenting benefit justifies shortening a hold-open time, narrowing an opening, reducing a detection range or disabling a sensor. That is not a hedge. It is the answer. If somebody in this trade suggests otherwise to you, that is a good moment to stop taking their advice generally.
The same applies to the second temptation, which is propping the door. A propped door is the worst of both worlds for scenting - it converts your controllable aperture into a permanent one, which is precisely the mall-front problem this bank spends so much time on - and it frequently conflicts with how the door and the building are meant to work. If your team props the door for deliveries or because the closer is slow, that is a maintenance conversation with the door company rather than a scenting one.
And the third, which is broader than doors and applies everywhere in this bank: never reduce ventilation or air exchange so that fragrance lasts longer. Not by closing a vent, not by turning down extraction, not by asking the mall to change anything, not by shutting a return grille because somebody read that it was "pulling the scent away". The store's air handling exists for the people in it, your staff included, who stand in that air eight to ten hours a day. A well-ventilated showroom is genuinely harder to scent, and this page says so plainly rather than pretending otherwise. You solve it with placement, sizing and level.
In a mall tenancy there is a fourth boundary that is contractual rather than ethical. The air handling serving your unit usually belongs to the landlord, the setpoints and fresh-air fraction are frequently not yours to touch, and your lease may explicitly forbid modification. The ducted machines in the SOSA range - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - are for buildings whose HVAC you actually control. A mall tenant usually does not, and a freestanding or wall-mounted machine is the honest answer there.
What you may legitimately do about the door is everything on the operational side of it. Keep the entrance matting clean and dry, because wet coir in a monsoon week has a smell of its own and it sits exactly where every nose in the building arrives. Keep the threshold clear so people cross it quickly rather than standing in it. Make sure the door is serviced, because a slow or juddering leaf holds the aperture open longer than the specification intends and that is a maintenance fault rather than a fragrance one. And if the store has a vestibule with two sets of doors, protect it - a lobby with a door at each end is the only structure in retail that genuinely separates two bodies of air while letting people through, and it is worth more to your interior than any machine.
Get out of the airstream. The single commonest installation error in retail is a unit standing near the entrance, because that is where the spare socket was. In a showroom with a busy automatic door that is close to the worst position in the building: a large share of what it produces is delivered straight into the part of the room that is being exchanged two hundred times a day. Move it inward. As a working rule, put it past the first line of cases, and put something between it and the door - a case run, a partition, a change of level, a display block. Line of sight to the aperture is a reasonable proxy for airstream, and if the machine can see the door, the door can see the machine.
Use the depth of the store. A showroom is not a single point; it is a gradient, and an automatic door makes that gradient steeper. Put the unit in the deep third, near the seating group, and let the front be almost nothing. That is not a compromise. It is the correct design, because the front of the store holds a passer-by for four minutes and the deep third holds a buyer for ninety, and the ninety is what sets the level.
Stay off the mechanical services. Do not stand a unit directly under a supply diffuser, where it will be blown across the ceiling and away, and do not stand one next to a return grille, where it will be drawn into the extract almost immediately. Both are common, both look like a mysterious loss of fragrance, and both are free to fix. Walk the ceiling before you choose the spot.
Respect ordinary retail prudence. Do not place a scenting unit above or beside the watchmaker's bench, open display trays or stock storage. That is prudence about where a device goes and nothing more - this page makes no claim of any kind, in either direction, about fragrance and watches, movements, dials, straps, cases or stock. What it does say is what SOSA publishes: the Vaayu is waterless cold-air nebulising with no water, no humidity and no wet residue, while the ultrasonics are cool-mist machines that put moisture into the air. That is a design distinction and a preference, and it is the honest reason a showroom with leather straps and a bench in the back tends to choose the waterless machine.
Use the timer rather than the dial. The Vaayu's Bluetooth app and timer let you scent trading hours and nothing else. The temptation with a leaky front is to run longer and harder to build up a reserve; what you actually get is a machine running at three in the morning into a closed showroom, and a room that is over-scented for the first hour of Monday and then behaves normally for the rest of the day. Consistency is the product, and a consistent low level beats a peak and a trough every time.
Then reset the level, downward. This is the part that feels wrong and is right. Once the unit has been moved into the depth of the store, it is delivering into a part of the room that holds - so the number that was needed when it stood by the door is now too high. Re-set it from the chair at minute forty-five, take one notch off, write the register and the number on a card taped to the machine, and leave it alone for a fortnight.
And accept the gradient as a specification. A showroom with a busy automatic door will always read as almost nothing at the threshold. If you want the threshold to communicate, do it with the things that work in ten seconds and that fragrance cannot do at all: the light level and colour temperature, the floor material underfoot, the drop in sound as the door closes behind somebody, the temperature change, and whether a human being looked up and greeted them.
- Tally door cycles for one full trading day - cycles, not customers.
- Move the unit past the first case line, out of sight of the aperture.
- Keep it clear of supply diffusers, return grilles, trays, storage and the bench.
- Reset the level from the chair at minute forty-five, then take one notch off.
Where the machine goes, which register, and the zone that gets nothing
Register barely enters into this page, and that is worth stating rather than padding. A busy automatic door does not change which of the seven registers belongs in your showroom; it changes where the machine stands and what number it runs at. If somebody tries to sell you a "stronger" register to beat a door, they are selling you the wrong variable.
The steer is the same as everywhere else in this bank: dry, clean and unsweet, held low. There are seven registers in the water-based Hotel Collection, each SOSA's own hotel-inspired interpretation, and SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand. Four are live candidates for a watch showroom. Quiet Luxury is white tea, bergamot and cedar, hushed and polished, and it is the default if you want the decision made for you. White Tea Serenity is white tea, aloe and cedar, clean and weightless, and it is the answer for a pale, glassy, minimal fit-out. Forest Suite is cedarwood, vetiver and green leaves, the driest of the four, and it reads as structural rather than decorative, which in a room full of strangers is a genuine advantage. Old-World Glamour is amber, violet and woods, and it is the heritage answer, held lower than anything else on the list because plush accumulates over a long sit faster than dry does.
Three do not belong on a watch floor at any setting. Lobby Bar is citrus, pepper and amber, bold and after-dark, and pepper is an announcing note in a room whose entire job is not to announce. Warm Welcome is citrus, floral and sandalwood, a genuine hotel threshold register, and in retail it is where the sweetness problem starts. Tea Garden is jasmine, green tea and white tea, the least risky floral in the collection, and still a floral - which on a retail floor reads as a choice somebody made, and a choice somebody made is what the naming test catches.
There is one place where the door does touch the register choice, and it is a caution rather than a rule. A showroom with a very busy entrance is a store where the owner is under constant temptation to escalate, because the threshold never reads as anything. If you have chosen a plush register like Old-World Glamour and you are also fighting a heavy door, that combination has a habit of ending at a number that is fine at the front and much too much at the tray - because the escalation was driven by a reading taken in the one part of the room that cannot hold anything. If you know you are prone to that, run one of the three dry registers instead. A dry register is more forgiving of a slightly high setting than a plush one.
I will not rank the seven on measured throw or longevity. SOSA does not publish that comparison, it would not be stable across buildings if it did, and the variables that dominate in a showroom with an automatic door - connected volume, ceiling height, cycle count, pressure difference, surface hardness, where the unit stands and what number it runs - are all yours rather than the blend's.
And the zones that get no register at all: the vestibule if you have one, the watchmaker's bench, the workshop, stock storage, the safe room and the back office. The entrance zone is not scented harder to fight the door; it is left alone on purpose, because that is where the exchange is and anything put there is being paid for twice.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · the deep third, and the default | White tea, bergamot and cedar. Hushed, polished and unsweet, run from a unit placed past the first case line and near the seating group. Dry registers are more forgiving of a slightly high number than plush ones, which matters in a store where the doorway constantly tempts you to escalate. |
| White Tea Serenity · pale, glassy showroom floors | White tea, aloe and cedar. Clean and weightless, and the register that most naturally reads as clean rather than as scented - useful in a showroom where dwell ranges from four minutes at the front to ninety at the tray and you do not get to choose which one you are dosing. |
| Forest Suite · timber, stone, planting | Cedarwood, vetiver and green leaves. The driest of the candidates, structural rather than decorative, and the one a mixed public most readily receives as part of the building rather than as an addition somebody made. |
| Nothing at all · the entrance zone, vestibule, bench, storage | The first few metres inside the door, any vestibule, the watchmaker's bench, the workshop, stock storage, the safe room and the back office. The entrance is not scented harder to fight the exchange - it is left alone on purpose, because anything put into an aperture that cycles two hundred times a day is being paid for twice. |
The buying answer, once the placement work is done, and it is worth doing the placement first because it often changes what you need.
For one enclosed viewing room behind a door that stays shut, the door on the shopfront is irrelevant and an ultrasonic is usually the whole purchase: the SOSA Boond at ₹899 for a small enclosed room, or the SOSA Sukoon at ₹1,899 for a viewing room or a compact floor, 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 lets you audition registers in your own air over five days each rather than choosing from a description. A collector lounge running eleven in the morning to nine at night is where the SOSA Megh at ₹3,499 and its 6 litre tank earns its place.
For the connected showroom floor, the SOSA Vaayu at ₹11,999 is the commercial answer, and the reason it suits this particular problem is mounting flexibility as much as capacity. It is freestanding, wall-mountable or HVAC-mountable, which means you are not tied to the socket the fit-out happened to leave by the door - and the whole remedy on this page is about getting the unit away from the door. It is rated for approximately 1000 cubic metres of connected air, SOSA's own copy also states 2,000 to 3,000 sq ft scented evenly, it takes a 400ml tank, runs on DC 12V / 1A at 5W so it needs a live socket, and carries CE, RoHS and SGS. Waterless cold-air nebulising of undiluted oil means no water, no humidity and no wet residue, which is a design fact and a preference in a store with leather straps, open trays and a bench, and not a protection claim of any kind.
Two systems, and they are not interchangeable. The ultrasonics are water-based; the Vaayu and the ducted machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - run waterless nebulising oil, and the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. The ducted pair belong in buildings whose air handling you control, which a mall tenant usually does not.
If you want no plug, no noise and nothing to switch off at a desk deep in the store, the SOSA reed diffusers are their own registers rather than Hotel Collection ones: Mountain Breeze at ₹849 is Himalayan pine, sage and cedar and sits closest to a showroom's woody direction; Morning Freshness at ₹749 is Malabar lemon, mint and eucalyptus; Garden Bloom at ₹799 is British rose and night-blooming jasmine; Evening Calm at ₹799 is Kashmir lavender and chamomile; Fresh Brew at ₹849 is Coorg coffee and Kerala vanilla. The 130ml is from ₹1,249, 300ml refills ₹2,399, 500ml ₹3,499, and a reed lasts about 6 to 10 weeks. A reed is local - it scents the few feet around it and will do nothing whatever about a door.
To go wider on the format question: whether your store needs a different strategy at all because the front closes is answered in does a standalone luxury watch store need a different scent strategy; the complaint that brings most owners to this subject is handled in why a boutique fragrance disappears whenever the entrance stays open; and the full mall planning page, with the volumes worked by hand, is mall HVAC, open entrances and high footfall.
What SOSA does not publish, and this page will not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time. A busy door does change how a machine is used, but SOSA publishes no consumption figure to adjust and no honest page would invent one. Send your floor plan, ceiling height, cycle count and the tissue test result to WhatsApp at +91 96192 18531. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition is a real SOSA service discussed there rather than priced on a page - though the cheaper honest answer comes first, which is that one of the seven registers held consistently already is a signature.
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
A watch boutique is a room where somebody sits down for an hour and a half to make a decision worth more than most people's cars. That is the fact that should govern everything about the air in it. Not the doorway, not the first impression, not the ten seconds a passer-by gets - the ninety minutes. A level that is lovely at minute one is tiring at minute sixty, and tiring is the last thing you want in the room where the tray comes out.
So my advice to every boutique owner is the same and it is slightly annoying: go lower than you want to. In luxury retail the tell is not that a room smells of nothing; it is that a customer can name what it smells of. The moment somebody can say "oh, that's a fragrance", the room has stopped being a place and started being a display, and a display is exactly what a serious buyer is trying to see past.
Two other honest things. Fragrance adds scent - it never subtracts one - so if the store has a source problem, a leather smell that has gone sour, a stale morning, a workshop bench that vents into the floor, no bottle solves it; air and cleaning do. And I will not tell you that a scent sells watches. Nobody honestly can. What a held, quiet, consistent room does is make a boutique easier to be in for ninety minutes and easier to recognise the second time - and in this trade that is worth having on its own terms.
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.

No SOSA product is an air-treatment device, and no claim is made here about any effect on a customer, a purchase decision, a transaction value or a product on display. SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any watch manufacturer. 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.
