That sounds like a technicality and it is the commonest failure in multi-site scenting. A group buys three machines, commissions the first store properly, writes "setting four" on a piece of paper, and rolls out setting four to the other two because consistency is the point. Then one shop is imperceptible and one is the shop everybody mentions, and the brand ends up less consistent than it was before anyone bought anything. The number is not the thing you are standardising. The experience is.
Take two of your own addresses. A smaller unit of 700 sq ft with a 10 ft ceiling is 7,000 cubic feet, and 7,000 divided by 35.3 is about 198 cubic metres. A bigger one at 1,400 sq ft with a 14 ft ceiling is 19,600 cubic feet, which divided by 35.3 is about 555 cubic metres. That is nearly three times the air - 19,600 divided by 7,000 is 2.8 - and the ceiling height alone accounts for a good part of it, which is why floor area on its own is never enough to size anything. The same setting in those two rooms produces two different shops.
Volume is only the first of five differences, and the other four are the ones that catch people out: how open the front is, how often the door cycles, what the room is made of, and what the air conditioning is doing. A shop with a shutter standing open onto the street has its first few feet effectively outdoors. A shop full of hanging cloth and soft goods behaves differently from a harder, emptier room. Two of your own stores are two different buildings, even when the fit-out drawings were the same.
And then the point that belongs specifically to a craft brand with more than one address, which I think is the interesting one. Across your stores, almost nothing is genuinely identical. The buildings differ, the street differs, the stock differs by the day, the staff differ, the light differs. The register is very nearly the only element that is literally the same in every room you operate. That is an argument for it being quiet and unsigned rather than characterful - because the one thing that is perfectly uniform across a group is also the thing that becomes conspicuous fastest if it has any personality at all.
Two limits, as always. I will not tell you that a scent sells anything: no footfall, enquiries, conversion, spend, repeat visits or recommendations. The honest ceiling is improved evaluations of a space and its service, longer dwell and stronger recall of a space, at moderate effect sizes. And fragrance adds scent and never removes it; no SOSA product treats, filters, dries, dehumidifies or purifies air.
What makes two of my own shops behave differently? Five things, in rough order of impact. Connected volume, which is floor area multiplied by ceiling height and not floor area alone. Aperture - whether the front is a sealed door or a shutter standing open onto the street, because an open front means the first few feet are effectively outdoor air. Door traffic, since a door cycling constantly exchanges air continuously. Materials, because a room full of hanging cloth and soft goods behaves differently from a harder, emptier one. And air conditioning, because output dropped into a supply airstream gets carried off and thinned before it reaches the room. Two shops built from the same drawings in different buildings are still two different rooms.
Should the flagship get something richer than the smaller stores? No. That is the one variation I would argue hardest against, because it converts your only genuinely uniform element into a ranking. A customer who uses two of your addresses should find the same business in both; a customer who uses only the smaller one should not be in the lesser version of your brand. If a flagship needs to feel like a flagship, do it with space, light, seating, stock depth and staffing - all of which are visible and defensible - rather than by giving one room a louder character. The register is the group's common thread, and a common thread works by being the same, not by being graded.
Why the number cannot travel, in arithmetic. Two of your own shops. Store A is 700 sq ft with a 10 ft ceiling: 700 multiplied by 10 is 7,000 cubic feet, and 7,000 divided by 35.3 is about 198 cubic metres. Store B is 1,400 sq ft with a 14 ft ceiling: 1,400 multiplied by 14 is 19,600 cubic feet, and 19,600 divided by 35.3 is about 555 cubic metres. Divide 19,600 by 7,000 and the second store holds 2.8 times the air of the first. A third at 1,000 sq ft and an 11 ft ceiling is 11,000 cubic feet, about 312 cubic metres, sitting between them. Those are three different rooms and they cannot take the same figure. Note also how much of that is ceiling: doubling the floor area doubles the volume, but so does going from a 7 ft mezzanine to a 14 ft shop height, and floor area is the number everybody quotes while ceiling height is the one nobody measures.
Then the four differences that are not volume, and they matter more than people expect. Aperture: if one address has a sealed door and another has a shutter standing open onto the pavement all day, the second is exchanging air with the street continuously and its first few feet are effectively outdoors. No setting fixes that, and the correct response is placement deeper into the room and a lower expectation at the threshold - never closing the front or reducing ventilation so the fragrance holds. Door traffic: a busy address with a door cycling every minute is a different room from a quiet one with the same plan. Materials: a shop dense with hanging cloth, soft goods and upholstery behaves differently from a harder, emptier room, which is why a store that is full in season and thinner out of it is not even the same room as itself. Air conditioning: output dropped into a supply airstream is carried off and thinned before it reaches the room, which is the single commonest reason one store's setting keeps creeping up while another's does not.
And do not assume two of your addresses are alike because they are both yours. Lucknow's commercial districts are of genuinely different ages: Hazratganj has been the city's shopping district since 1827, with a street grain and a Victorian-influenced architecture that came out of a nineteenth-century redesign, and it went through a coordinated facade and signage scheme around its two-hundredth year. Gomti Nagar is a planned township taken up by the Lucknow Development Authority in the 1980s and occupied from 1995 onwards. A unit in one and a unit in the other are not the same kind of building and I would not guess at either from a page - which is exactly the point. Measure each address. Commission each address. Never infer one from the other.
The connected-volume rule applies at every site separately. A coverage rating assumes one connected body of air and scent does not travel through a closed door. So at each address, walk it with a plan and mark every door that genuinely stays shut in trading hours. Trial rooms are separate volumes and take nothing. Stockrooms take nothing, because unsold cloth should smell of itself. Offices, alteration benches and packing areas take nothing. What is left connected is what the machine at that address is actually being asked to hold, and it will be a different number at every store.
And here is the part specific to a craft brand. Across your group, what is genuinely identical? Not the building, not the street, not the light, not the staff, and not the stock, which moves daily. The register is very nearly the only thing that is literally the same in every room you operate - which is a much stronger reason to keep it than most brand arguments, and also a strong reason to keep it quiet. A perfectly uniform element is the one a customer can notice in two places and compare, and anything with personality becomes conspicuous fastest under those conditions. Unsigned, low, and everywhere. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, build the settings card, because multi-site scenting fails through paperwork rather than through equipment. One card per address, kept with the machine, carrying five lines: which machine, which register, the exact setting, the hours it runs, and the date it was last changed and by whom. Add the store's connected volume in cubic metres at the top, worked out as area multiplied by ceiling height divided by 35.3, so that anybody looking at two cards can see instantly why the numbers differ. One named person per group may change a card, and every change needs a reason and a date.
Then run the commissioning visit properly at each address, and do it separately even if the stores look alike on a drawing. Someone who does not work in that store, who has been outside at least ten minutes, walks in and is asked an open question: is there anything about this room you would change. Not "can you smell the fragrance", which plants the answer. If they name a smell, come down. In a craft shop where customers spend a long time at a table, also ask at minute fifty of a real appointment rather than at the door, because that is who the level is for.
The cross-store check is the one nobody does and it is the most useful hour in the whole exercise. Take one person and have them visit two of your addresses on the same day, in the same weather, with a gap of an hour between. Ask them one question only: did those two shops feel like the same business? If the answer involves one being noticeably stronger, adjust the number at that address until the answer stops involving the air at all. That is what matching the perceived level actually means in practice, and it is why the numbers on your cards should not agree.
Two group-level disciplines worth writing into whatever passes for an operations manual. First, never change the register - not for a season, not for a festival, not for a campaign, not because a new store is opening. The register is the only genuinely uniform element in the group and its whole value is sameness; swapping it spends the thing you were buying. Change the setting across the year if you need to, and in Lucknow you probably do, because April and May are hot and dry with the May mean daily maximum near 39.9 degrees C, July and August are wet, and the winter from late November to February is cold and damp with fog common in December and January. Three settings per store, which means three numbers on each card and nine numbers across three shops, none of which need agree with each other.
Second, anyone on any floor can switch a named unit off without asking a manager. Your staff stand in that air eight to ten hours and are the most exposed people in each building and the least reliable judges of the level, and in a group the risk is that a head-office number outranks a person standing in the room. It must not. A reported reaction is a recalibration signal, not a tolerance problem, and no health or allergy claim is made in either direction.
Identical register, different numbers - the five things that make two of your own shops different rooms
Three questions decide multi-site scenting, and only one of them is about fragrance. What is identical across the group? What must be calibrated per address? And who is allowed to change a number?
The answers are short. Identical: the register, permanently. Calibrated: the level, at every address, by someone standing in that room. Allowed to change it: one named person, with a reason and a date. Everything else on this page is the reasoning behind those three lines.
Do the arithmetic for the whole group in one sitting, because seeing the numbers side by side settles most of the argument. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A 700 sq ft store at 10 ft is 7,000 cubic feet, about 198 cubic metres. A 1,000 sq ft store at 11 ft is 11,000 cubic feet, about 312. A 1,400 sq ft store at 14 ft is 19,600 cubic feet, about 555. A SOSA Vaayu at ₹11,999 is published for approximately 1000 cubic metres of connected air, so all three sit comfortably inside what one machine is rated for - which is the recurring finding in this bank. The machine is not the constraint at any of your addresses. The setting is, and it is a different setting at each one.
Be careful with the word connected at every site independently. The 1,400 sq ft store might have 1,400 sq ft on the drawing and only 1,050 connected, because a doored office, a stockroom and three trial rooms are separate volumes. The 700 sq ft store might be almost entirely connected. So the volume you are scenting is not the volume on the lease, and two stores with similar lettable areas can have quite different connected volumes once the doors are accounted for.
One more thing that is specific to a craft business rather than to retail generally. Your stock is soft, it hangs, and there is a lot of it - and it is the product. Two consequences follow at group level. First, at every address the unit goes away from open stock, away from hanging garments and away from the table where pieces are examined, into circulation space, out of an air conditioning supply airstream and away from the entrance. Second, a store that carries more stock than another is a materially different room, and stock density changes with the season, which is one more reason the number on the card is a local number. I am making no claim in either direction about fragrance protecting, preserving, damaging or improving fabric or hand embroidery; this is ordinary retail placement and nothing more.
One register, in every store, for as long as the business exists. Not a family of related registers, not a flagship variant, not a seasonal rotation. One. 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 - and the choice between them matters far less than the decision to hold whichever one you choose.
The reason is that consistency, not uniqueness, is what a signature is made of. This is the sentence I repeat most often and it is most literally true in a group. A register held at the same perceived level in every room, every trading day, for years, becomes part of how your business is recognised. The same register changed every eighteen months, or graded by store, is just a series of smells. Nothing about that requires the blend to be exclusive to you, which is why I give the cheaper honest answer before anyone asks about bespoke work: one of the seven, held, already is a signature.
Now the craft-brand argument, which I think is the strongest thing on this page. Go through what is actually identical across your addresses. The buildings are different ages and different shapes. The streets are different. The daylight is different. The staff are different people with different knowledge. The stock differs by the day and by the season, because handwork is not uniform and that is the point of it. The fit-out is as close as you can get it and still not the same. The register is very nearly the only element that is literally, exactly the same in every room you operate.
And that is precisely why it should be quiet. A perfectly uniform element is the one a customer can encounter twice and compare directly, and anything with personality becomes conspicuous fastest under comparison. A characterful register experienced in two of your shops in one week does not read as a brand asset; it reads as a decision somebody made, repeated. An unsigned, very low register experienced twice reads as nothing at all, and then, over years, as the shop being the shop. Unsigned, low, and everywhere.
The one variation I would argue hardest against is grading by store - something richer for the flagship, something plainer for the smaller addresses. It converts your only uniform element into a ranking, and it tells a customer who only ever uses the smaller shop that they are in the lesser version of your business. If a flagship needs to feel like a flagship, do it with space, light, seating, stock depth and staffing, all of which are visible and defensible.
And to say it once, because a craft group always asks: there is no chikankari, heritage, attar, oudh, rose-water or "traditionally Indian" register in the commercial range. SOSA does not make one for machines; the ultrasonics and the Vaayu run the seven Hotel Collection registers and nothing else, and the reeds are their own five scents. Bespoke composition is a real SOSA service, discussed on WhatsApp rather than priced on a page - and it would not solve the problem this page is about, because the problem is not which smell it is.
1. Connected volume. Area multiplied by ceiling height, divided by 35.3. A 700 sq ft store at 10 ft is 7,000 cubic feet, about 198 cubic metres; a 1,400 sq ft store at 14 ft is 19,600 cubic feet, about 555. That is 2.8 times the air. Ceiling height is the half of the sum that nobody measures and it is doing as much work as the floor area. And it is connected volume, not lettable area: doored offices, stockrooms and trial rooms come out of the total at every site.
2. Aperture. A sealed door and a shutter standing open onto the pavement are two different buildings from the air's point of view. An open front means continuous exchange with the street and a first few feet that are effectively outdoors, and there is no setting that overcomes it. Place deeper into the room, expect nothing at the threshold, and never respond by closing the shop up or reducing ventilation so the fragrance holds. That advice gets written in softer phrasings all the time and it is the most harmful sentence in commercial scenting.
3. Door traffic. Two shops with the same plan and the same volume are different rooms if one has a door cycling every minute and the other has a door opening six times an hour. Continuous exchange is continuous dilution, and it also means the busiest address - which is the one you would most like to feel right - is the hardest to hold a level in.
4. Materials and stock density. A room dense with hanging cloth, soft goods and upholstery behaves differently from a harder, sparser room. In a craft business this varies by season as well as by address, because a store carrying heavy stock before a wedding season is not the same room as the same store in a quiet month.
5. Air conditioning. Output dropped into a supply airstream gets carried off and thinned before it reaches the room, which is the commonest reason a store's setting creeps upward: the machine is not weak, it is badly placed. At every address, keep the unit out of the supply stream, off the entrance, and away from open stock and rails.
How to calibrate, concretely. At each store, start lower than you think and raise slowly rather than starting high and coming down, because a room that has been over-scented takes a while to read honestly. Use a visitor who has been outside at least ten minutes and ask an open question. In a craft shop, ask at minute fifty of a real appointment as well as at the door, because the customer at the table is who the level is for. Then write the number on that store's card and leave it alone.
And run the cross-store check. One person, two of your addresses, same day, same weather, an hour apart, one question: did those feel like the same business? Adjust until the answer stops mentioning the air. That is the only meaningful definition of "identical" in a group, and it is why the cards will not agree.
Adaptation is the engine of it. The people in each shop stop receiving a constant ambient smell fairly quickly, and the people with the power to change the setting are therefore the people least able to judge it. Across three addresses that produces three independent upward drifts at three different rates, and after a year you have exactly the inconsistency the whole exercise was meant to prevent - with the additional problem that nobody can see it, because nobody stands in two shops on the same afternoon.
The settings card is the defence, and it is unglamorous. One card per address, kept with the machine. On it: the store's connected volume in cubic metres, the machine, the register, the exact setting, the hours, and the date and initials of the last change. That card is the record of a decision, and a decision has an owner.
One named person changes a card, with a reason and a date. Not whoever is on shift, not whoever mentioned that it seemed weak. And the rule that matters most in a group: never copy a number from one card to another. If store three is being commissioned, it gets its own afternoon and its own visitor, not store one's figure. A number that travels between sites is the single most common defect in multi-site scenting and it is entirely avoidable.
Quarterly, run the visitor test at every address rather than at the one nearest head office. Rotate who does it. Ask an open question. If a smell gets named at any site, that site comes down. And at least twice a year, do the cross-store check on the same day.
The override that outranks all of it. Anyone on any floor can switch a named unit off without asking a manager. Staff stand in that air eight to ten hours a day and are the most exposed people in each building, and in a group there is a specific danger that a written head-office number is treated as outranking a person standing in the room. It does not. A reported reaction brings the level down or switches the unit off that day, nobody has to justify it, and the card gets a note. No health or allergy claim is made in either direction.
And the source rule, at every address independently. Before any of this, do the morning test at each shop: arrive first thing, before staff, before stock movement, before the air conditioning has run. Whatever meets you at the door is what that shop actually smells of. If it is damp in August, or a new fit-out still off-gassing at the newest address, a register laid on top gives you both at once, and most people find that worse than the original. Fragrance adds scent and does not remove, neutralise, absorb, deodorise, dry or purify odour; no SOSA product treats, filters, dries, dehumidifies or purifies air. Source, then ventilation, then cleaning, then fragrance. Every time, at every site.
- Work out each store's connected volume: area times height, divided by 35.3.
- Commission every address separately, starting low and raising slowly.
- Write a card per store: machine, register, setting, hours, date and initials.
- Twice a year, send one person to two shops in a day and ask if they match.
One register for the group, and a settings card for each address
So, which register for the group, and how do you pick one you will still be running in eight years?
First, pick it in the hardest room, not the easiest one. Audition in whichever of your addresses is the most difficult - the largest volume, or the one with the open front, or the busiest door. If a register works there at a level nobody remarks on, it will work everywhere else in the group. Picking it in the flagship and rolling it out is how a group ends up with two quiet shops and one that everybody mentions.
Then the seven, and the steer is narrow. All seven are in the water-based Hotel Collection, each SOSA's own hotel-inspired interpretation; SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand. For a craft group where customers handle cloth closely: 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 is what you want in the one element that is identical everywhere. Quiet Luxury is white tea, bergamot and cedar - hushed, polished and unsweet, the one-decision default for a long-established business. Forest Suite is cedarwood, vetiver and green leaves - the driest of the three and the one that reads as part of the building, which is useful if your addresses vary in age and materials, because a structural register sits differently in each room without ever seeming imported.
The ones I would keep out of a multi-site craft group. Old-World Glamour (amber, violet and woods) is plush and evening-elegant, and plush is the worst thing to make perfectly uniform, because it is the most noticeable when encountered twice. Lobby Bar (citrus, pepper and amber) is bold and after-dark; a theatrical register turned down is a quiet theatrical register, never an inconspicuous one. Warm Welcome (citrus, floral and sandalwood) is a threshold register, designed for arrival, and your regulars are not crossing a threshold, they are coming into a shop they know. Tea Garden (jasmine, green tea and white tea) is the least risky floral in the collection, and even so I would keep a floral of any weight away from rails of hanging cloth in every one of your shops.
I will not rank those seven against each other on measured throw or longevity. SOSA does not publish that comparison, and the variables that dominate belong to each of your buildings rather than to the blend - which is, in a sense, the entire argument of this page restated.
And there is no chikankari, attar, oudh, rose-water or "traditionally Indian" register in the commercial range. SOSA does not make one for machines. Bespoke composition is a real SOSA service, discussed on WhatsApp rather than priced on a page - but the cheaper honest answer comes first: one of the seven held at the same perceived level in every store, every trading day, already is a signature, because consistency makes a signature and uniqueness does not. In a group that is not a compromise, it is the strongest version of the argument, because sameness across addresses is exactly what you are trying to buy.
| Scent | Why it suits the mood |
|---|---|
| The register · identical, permanently | One register for the whole group, never graded by store and never changed for a season, a festival or a campaign. It is the only element that is literally the same in every room you operate, which is why it is worth keeping and why it should be quiet and unsigned rather than characterful. |
| The setting number · never travels | Calibrated at each address by someone standing in that room, starting low and raised slowly. A 700 sq ft store at 10 ft holds about 198 cubic metres and a 1,400 sq ft store at 14 ft about 555, so the cards will not agree. If two of your cards show the same figure, that is a coincidence to check rather than a policy to be pleased about. |
| The discipline · identical everywhere | A settings card per store, one named person allowed to change it, a reason and a date, a quarterly visitor test at every address, a twice-yearly cross-store check, and the standing rule that anyone on any floor can switch a named unit off without asking. The process is the part that should be uniform. |
| Rooms that get nothing · the same list at every site | Trial rooms, stockrooms, packing and alteration benches, and offices. Each is a separate volume behind a door, and unsold cloth should smell of itself rather than of your room. This list does not vary by address, by store size or by how important the branch is. |
So the buying answer for a group, and it is the same shape as for one shop, repeated honestly.
For a connected retail floor at each address, 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 - a plain design preference in a city with two damp stretches rather than one, and never a claim to control humidity or treat a damp 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, which means all three of the example stores above sit well inside what a single machine is rated for. The Bluetooth app and timer is the whole reason this is the right machine for a group rather than a single shop: it is what lets each address hold a written number through trading hours and across three seasons without anybody nudging a dial. 400ml tank, freestanding or wall and HVAC mount, DC 12V / 1A at 5W so each site needs a live socket, CE, RoHS and SGS.
For a single enclosed room at any address - an office, a private viewing room, a reception where somebody sits - an ultrasonic is usually the whole purchase: a SOSA Boond at ₹899 or a SOSA Sukoon at ₹1,899, 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 - and in a group, audition in your hardest room rather than your nicest one. The two systems are not interchangeable: the ultrasonics are water-based cool-mist machines, while the Vaayu and the ducted Aangan at ₹25,999 (approximately 8,000 to 10,000 sq ft) and Meenar at ₹38,500 (approximately 12,000 to 18,000 sq ft) run waterless nebulising oil. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine.
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. One group-level warning about reeds: because they are passive, with nothing to switch off and no number to write down, they are the hardest thing to keep consistent across several addresses. They are excellent at a single billing desk and a poor instrument for a brand standard.
To go deeper: the level at every one of your addresses is governed by dwell, and the full argument is in how subtle the fragrance should be when customers examine fabrics and embroidery for an hour. The one room that gets nothing at every site has its own page in should trial rooms be less scented than the main fashion floor. And the question of what a craft brand should be saying with its air at all is how a craft-led business can use scent without turning culture into a theme-park experience.
What SOSA does not publish, and what this page will therefore not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time.

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.
