Take the second half first, because it is the part nobody tells you. When you are standing in your own half-finished shop you are not calibrating against your trading room. You are calibrating against a building site - against dust, cut timber, adhesive, fresh paint, a floor that is not down yet and a ceiling that is open. Everything you choose in that state you choose against that baseline, and a level that seems modest in a room with no stock, no people and no soft goods in it is a loud level in the finished shop on an ordinary Wednesday. 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 owner in an empty room.
There is a second, more physical reason to wait. A freshly renovated space is off-gassing. Paint, adhesive, laminate, sealant, new carpet, new upholstery and new joinery all put their own smell into a room for a while after the work is done, and the honest advice is one nobody in my industry wants to give: wait, ventilate, and judge by nose first thing in the morning before anyone has been in the building. I will not tell you how many days or weeks that takes, because it depends on what was used, how much air the room gets and how warm it is, and anybody who gives you a fixed number is guessing. Fragrance adds a smell; it does not remove one. Put a register on top of a room that is still off-gassing and you have both, which is worse than either.
And keep the point of the exercise in view, because a refit is exactly when it gets lost. In a shop people have used for years you are not creating an impression, you are protecting one. The customer who comes back after the shutters go up is checking the new version against the one in their head, and they are already primed to notice difference because the paint is fresh and the counter has moved. That is the week when an ambient level that would normally pass unremarked gets attributed - correctly - to the renovation, and the sentence you least want is the one that starts "it feels different now". The specification does not change because the room is new. Go so low that nobody remarks on it.
The limits, up front. I will not tell you that a scent sells anything: no footfall, enquiries, repeat visits or spend. The honest ceiling is improved evaluations of a space and its service, longer dwell and stronger recall of a space, at moderate effect sizes. No SOSA product treats, filters, dries or purifies air, and nothing here is building, fit-out, electrical or fire advice - your contractor, your electrician and the people responsible for the building decide what goes into it.
How long should I wait before running fragrance in a newly renovated shop? Long enough that the new fit-out has stopped announcing itself, and I will not give you a number of days because the honest answer depends on what materials went in, how much air the room gets and how warm it is. What I can give you is the test. Come in first thing in the morning, before staff, before stock movement, before the air conditioning has run - that is the room at its most honest, because everything has had all night to accumulate and nothing has been disturbed. If what you meet is paint, adhesive, laminate or new carpet, you are not ready. Ventilate, wait, come back another morning. Fragrance adds scent and never removes it, and no SOSA product treats, filters or purifies air, so a register on top of off-gassing gives you both smells at once.
What should I ask the contractor to leave me? Four things, none of them expensive at drawing stage. One: a live 5 amp socket at the position you have chosen, because the Vaayu is mains powered at DC 12V / 1A and 5W and it needs one. Two: a mount point or a shelf at a sensible height if the unit is going on a wall rather than standing free. Three: a position that is not in the air conditioning supply airstream, because output dropped into a supply stream gets carried away and thinned before it reaches the room, and not in a dead corner either. Four: a position away from the entrance, especially if your front opens onto the street, because the first few feet of an open-fronted shop are effectively outdoor air. Ask for those on the drawing, not as a favour later.
Do not choose the level now, and do not choose it in the first fortnight of trading either. Here is the mechanism, because it is the part of this page worth keeping. Your nose calibrates against whatever it has been in. During a fit-out you have been in dust, solvent, cut timber and fresh paint, so a small fragrance signal reads as small. In the finished shop - with stock on the shelves, fabric and upholstery absorbing, people in the room and the front door cycling - the same setting reads quite differently, and the direction is almost always louder than you intended, because a bare room is acoustically and olfactively dead and a stocked one is not. Every over-scented commercial space I have been asked to look at was set during or just after a fit-out, by a sincere owner in an empty room. Fit the socket, leave the unit off, and set the level when the shop is trading normally.
Let the building finish off-gassing, and judge it by nose first thing in the morning. New paint, adhesive, sealant, laminate, carpet, foam and joinery all release their own smell for a period after the work, and that is a source, not an air problem you can cover. The order is the same as it always is: source, then ventilation, then cleaning, then fragrance. So ventilate properly - and I mean more air, never less; I will never tell you to close a vent or keep a door shut so a fragrance holds - and then use the morning test. Arrive before staff, before stock is moved, before the air conditioning has run. That is the honest version of the room, because everything has had the whole night to accumulate and nothing has been stirred. If the fit-out is the first thing you meet at the door, you are not ready. Come back another morning. I am not going to give you a number of days and neither should anyone else, because it depends on the materials, the air exchange and the temperature, and in Lucknow that last one swings hard between a 39 degree May and a January day that only reaches about 21.
Guard against over-signalling, because this is the month it happens. A refit puts every decision on the table at once - colour, counter, lighting, signage, uniforms, music, packaging, air - and a new room makes each addition feel justified. That is the trap. In a business whose asset is being recognised, six changes delivered in one weekend read as a different business under the same name. If you are reopening after a renovation, the air is the thing to introduce last and quietest, well after the reopening, when the shop has settled back into being itself. A returning customer in reopening week is already looking for difference; do not hand them one more.
And take the local precedent seriously, because it is unusually apt. Hazratganj has been the city's shopping district since 1827, and around its two-hundredth year the whole street went through a coordinated facade and signage scheme - rooftop hoardings and encroachments removed, buildings painted a uniform cream and pink, uniform signage, stone pavements, heritage-style lighting. That was a renovation at the scale of a district, and what it did was make the street quieter. It is the best available argument that modernising and getting louder are not the same move, and it is standing outside your own shutters while you do this. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, write four lines into the drawing set rather than into an email: the unit position, a live socket at it, the mount height, and the note that it must not sit in the air conditioning supply airstream or within a few feet of the entrance. Drawings get built. Emails get forgotten in week three when the electrician is on site and somebody has to decide something quickly.
Then build the waiting period into the plan so it is not a disappointment later. It is much easier to accept "we will switch it on eight weeks after reopening" as a plan than to discover in reopening week that switching it on would be a mistake. Put a date in the diary, not a feeling.
A note on the reopening itself, because owners ask. The temptation is to have the room at its best on the day the shutters go up, and the air is the least useful place to spend that impulse. On reopening day the room already has fresh paint, new light, stock properly faced and staff paying attention - that is the highest-signal version of your shop it will ever be. Adding a fragrance on top of that is adding to the loudest day rather than to the ordinary Tuesday, and the ordinary Tuesday is what the business actually runs on.
Two practical points about the season you reopen in, which is a real variable in this city rather than a decorative one. If you finish in April or May, the outside air is genuinely hot and genuinely dry - the mean daily maximum in May runs near 39.9 degrees C and the year's humidity trough is in those same hottest months - and air conditioning will be running hard, which means faster air movement and a room that clears quickly. If you finish in December or January, you are at the other end: cold days that only reach about 21.4 degrees C, mean minima near 7.8, and fog common through both months, with the building closed up much more of the day. The same setting behaves differently in those two rooms. That is an argument for one register with different written settings, not for two registers.
And the standing rule, from the day the unit is switched on. Anyone on the floor can switch a named unit off without asking a manager. Staff stand in that air eight to ten hours and are 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 in either direction.
Why the drawings being open is the real argument - and why the same week is the riskiest week to decide a level
Three things decide whether introducing a register during a renovation goes well: what you build in, when you switch it on, and who judges the level. The first is cheap and time-limited, the second is where the mistake lives, and the third is the part almost everybody gets wrong because they use their own nose.
Do the arithmetic while the plan is in front of you, because a refit is when people buy the wrong size. A single-unit shop of 1,000 sq ft at a 12 ft ceiling is 12,000 cubic feet, which divided by 35.3 is about 340 cubic metres. At 700 sq ft and 10 ft it is 7,000 cubic feet, about 198 cubic metres. A larger floor at 1,500 sq ft and 10 ft is 15,000 cubic feet, about 425 cubic metres. A SOSA Vaayu at ₹11,999 is published for approximately 1000 cubic metres of connected air, so the ordinary Lucknow retail unit sits at a third or a fifth of what the machine is rated for. The machine is not the constraint. The setting is - and a refit is the moment that truth is easiest to forget, because a new shop feels like an occasion for the bigger number.
The word connected matters more during a renovation than at any other time, because the renovation is when the doors get decided. A coverage rating assumes one connected body of air; scent does not travel through a closed door. So if the plan introduces a trial room, a viewing room, a private counter or an office with a door that will genuinely stay shut, the plan has created separate volumes, and you should know that now rather than discover it later. The reverse is also worth catching at drawing stage: a new open stair or a removed partition joins two volumes that used to be separate, and doubles the air a single unit is being asked to hold.
Finally, be honest about the front. If the renovation keeps a shutter or a door that stands open onto the street through trading hours, the front few feet of your shop are effectively outdoor air and no machine and no setting changes that. That is not a reason to seal the shop - never reduce ventilation to make a fragrance last longer - it is a reason to place the unit deeper into the room and to expect nothing at the threshold.
The socket. The Vaayu is mains powered at DC 12V / 1A and 5W, so it needs a live socket where it is going to live. That is a trivial line item on a drawing and a chased wall or a visible trunking run later. Worse, a shop without a socket in the right place ends up with the unit wherever the nearest free socket happens to be, which is usually behind the counter or beside the door - the two worst positions in the building, one because nothing reaches the room and one because everything goes straight outside.
The mount point. The Vaayu lays flat and stands free, or mounts to a wall or into HVAC. If the intention is a wall, decide the height and the fixing now. Out of reach and out of casual sight is the target, for the same reason the setting gets written down: a unit that anybody can nudge will be nudged.
Away from the air conditioning supply. This one is invisible on a plan and decides more than any other placement choice. Output dropped into a supply airstream is picked up, carried and thinned before it reaches the room, which is why owners with a unit under a grille conclude they need a bigger machine. The opposite error is a dead corner where the output never joins the room's air at all. The position you want is in the room's normal circulation but not in the blast.
Away from the entrance. If your front opens onto the street, the first few feet of the shop are exchanging with outdoor air constantly, and a unit placed there is scenting the pavement. Place deeper. If the renovation is putting in a proper closing door, the calculation changes and you should note that on the drawing too, because a shop that will now hold its air is a shop that needs a lower setting than the one you were imagining.
One more thing worth asking for while you have a contractor's attention, and it has nothing to do with fragrance: get the ventilation and extraction right, and get the washroom extract and any back-of-house extract working properly. That is the layer under everything on this page. Fragrance adds scent and never removes odour, so if the finished shop has a source, no machine and no setting will help - and the renovation is the only cheap opportunity you will get to fix it.
You are calibrating against the wrong room. A half-finished shop is dusty, solvent-laden, empty of stock, empty of people and empty of soft goods. Your nose has been sitting in that for weeks. Into that baseline, a fragrance has to work hard to register at all, and so you set it where it registers. Then the shop fills up - stock, fabric, packaging, upholstery, customers, staff, a door that opens - and the same setting behaves completely differently. An empty hard room and a stocked working room are not the same acoustic or olfactive space, and the finished version almost always reads louder than the version you set.
A renovation is also when a business over-signals generally. Everything is new at once, so every additional new thing feels consistent with the project rather than like an extra. This is how a trusted shop ends up with a new colour, a new logo, a new counter position, new uniforms, music and a fragrance all arriving in the same fortnight. Individually each might be defensible. Together they read as a different business trading under a familiar name, and the customer who has been coming for twenty years does not have a way to separate them - they simply register that the place is not the place. In a business whose asset is recognition, that is the most expensive possible outcome of a successful renovation.
And the reopening is the worst week of all to judge anything. Reopening week is the highest-signal week your shop will ever have: fresh paint, new light, full stock, staff on their best form, people coming specifically to look. Everyone's perception is heightened and yours most of all. A level set in that week is set against an occasion, and it will then run for the next two years of ordinary Tuesdays.
The practical instruction that falls out of this is simple and unpopular: fit the infrastructure, leave the machine off, reopen without it, and introduce the air weeks later as its own small decision. Nobody will notice it arriving, which is exactly the point. And when you do set it, do not use your own nose. Use somebody who has been outside for ten minutes and does not work for you, ask them an open question rather than "can you smell the fragrance?", and take the answer seriously. If they can name what the room smells of, it is too high.
What is actually happening. Paint, adhesive, sealant, laminate, new carpet, foam, upholstery and new joinery all release their own smell into a room for a period after installation. That is a source. It is not an air-quality problem I am qualified to discuss and this page makes no air-quality claim of any kind; it is simply a new room smelling of the new things in it, which every fit-out does.
What fragrance does about it: nothing. Fragrance adds scent. It does not remove, neutralise, absorb, deodorise or mask away anything, and no SOSA product treats, filters, dries, dehumidifies or purifies air - not the Vaayu at ₹11,999, not an ₹899 Boond, not a ₹749 reed. Run a register into a room that is still off-gassing and you get the fit-out and the register, layered, which almost everyone finds worse than the fit-out alone. Worse commercially, you will have taught yourself that the fragrance is unpleasant when the problem was timing.
The order, and the ventilation rule. Source, then ventilation, then cleaning, then fragrance. Ventilation here means more air - open the shop up outside trading hours, get a path rather than a gap by opening more than one thing at once, run extract fans, and ask whoever handles the building's air to check that mechanical extract is actually working. I will never tell you to reduce ventilation, close a vent or keep a door shut so that a fragrance lasts longer. That advice appears in softer phrasings all over my industry and it is the most harmful sentence in commercial scenting, and it is at its most harmful in a newly finished room.
The test, and why it is a morning test. Come in first thing, before staff, before stock is moved, before the air conditioning has run. The room has had all night to accumulate and nobody has disturbed it, which makes that the most honest reading you will get. Stand three steps inside the door and give it sixty seconds. If what you meet is paint, adhesive, laminate or new carpet, you are not ready: ventilate more, and come back on another morning. When the room reads as a room rather than as a fit-out, you can start thinking about a level.
Why I will not give you a number. Because it depends on which materials were used and how much, how much air the space gets, and how warm it is - and those are yours, not mine. SOSA does not publish a figure for it and I am not going to invent one. In Lucknow the temperature variable alone is large: a room finished in a 39 degree May behaves differently from the same room finished in a January whose days reach only about 21 degrees C and whose mornings are frequently foggy, with the building closed up far more of the time. Judge the room, not the calendar.
- Put the unit position, a live socket, and the mount height on the drawing set.
- Keep it out of the AC supply airstream and away from a front that opens to the street.
- Fix ventilation and extraction now - it is the only cheap chance you will get.
- Reopen with the machine off, then set a level weeks later using a visitor's nose.
What to install now, and why you should not switch it on for a while
Assume the fit-out has settled, the shop is trading normally and the morning test reads as a room rather than as a building site. Now the register, and the level - which matters more.
The volume first. Walk the finished plan and mark every door that will genuinely stay shut in trading hours, because each ends one volume and begins another. The main floor is what you are scenting. A new trial room, a viewing room or a private counter created by the renovation gets nothing or the very least of anything - a trial room is the smallest enclosed volume in a shop and holds one person at close quarters, and a viewing room holds a few people for a long time. Stockrooms get nothing, because your stock should not carry the room home with a customer.
The level. Set it for the longest-staying customer and for their fourth visit, not for the doorway and not for reopening week. And set it with somebody else's nose: after a renovation your own is the least reliable instrument in the building, because it has spent two months in solvent and dust and then two weeks in a room you are proud of.
The register. 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 - white tea, bergamot and cedar, hushed and polished and unsweet - is what I would run in a long-established shop given one decision. White Tea Serenity - white tea, aloe and cedar, clean and weightless and spa-like - suits a renovation that has made the room brighter and harder-surfaced, because it sits with that rather than arguing with it. Forest Suite - cedarwood, vetiver and green leaves - is the driest of the three and reads as part of the building rather than as a decision, which is useful where the refit has put in timber and stone and anything sweeter would be identified immediately.
What I would keep out of a newly renovated legacy shop. Lobby Bar is citrus, pepper and amber, bold and after-dark, and 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 over a long sit in a way that dry does not. Warm Welcome is citrus, floral and sandalwood, a genuine hotel-threshold register, which is exactly the instinct a reopening encourages and exactly the instinct to resist. 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 shop where people handle goods 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: 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 trading day already is a signature, because consistency makes a signature and uniqueness does not.
One standing arrangement, written into the reopening notes rather than remembered. Anyone on the floor can switch a named unit off without asking a manager. Staff are in that air eight to ten hours a day and a reported reaction is a recalibration signal, not a tolerance problem. No health or allergy claim is made in either direction.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · the default when the shop reopens as itself | White tea, bergamot and cedar. Hushed, polished and unsweet, and what I would choose for a long-established store with one decision and no further information. It carries a little presence without becoming what a returning customer thinks about in the week they are already looking for differences. |
| White Tea Serenity · a brighter, harder-surfaced refit | White tea, aloe and cedar. Clean, weightless and spa-like, the register that reads as clean rather than as scented. Where the renovation has raised the light level and put in harder surfaces, this sits with the new room instead of adding a second idea to it. |
| Forest Suite · a refit in timber and stone | Cedarwood, vetiver and green leaves. The driest of the shortlist and the one that reads as structural, so it is received as a property of the building rather than a choice somebody made. Useful where the materials are the point of the renovation. |
| Nothing yet · the whole of reopening week, and until the morning test passes | Not a lower setting - nothing at all. A new fit-out is off-gassing and fragrance adds scent rather than removing it, so a register on top gives you both. Reopening week is also the highest-signal week your shop will ever have and the worst possible baseline for a level that will then run for two years of ordinary Tuesdays. |
So the buying answer. For one enclosed room created by the renovation - an office, a viewing room, a counter with a door - 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 audition them after the fit-out has settled, not during, and judge on day five rather than the first afternoon.
For the connected retail floor the answer is the SOSA Vaayu at ₹11,999: waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue. 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 live socket, CE, RoHS and SGS. The app matters here more than anywhere, because a renovation is exactly the moment a setting gets nudged by whoever is on site: the timer lets you run trading hours only and write the setting down, with one for a dry April, 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 (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.
If you want no plug, no noise and nothing to switch off - which during a renovation is a genuinely attractive proposition - the SOSA reed diffusers are their own registers rather than Hotel Collection ones, from ₹749, with Mountain Breeze ₹849 the driest, alongside Garden Bloom ₹799, Evening Calm ₹799 and Fresh Brew ₹849. 130ml from ₹1,249, lasting about 6 to 10 weeks. A reed scents the few feet around it and will not fill a shop - which after a refit is sometimes exactly right, because a desk was the only place you wanted anything.
To go deeper: the full ranking of what to change in a trusted shop, with the test that governs all of it, is in how to make a thirty-year-old Lucknow business feel more premium without loyal customers feeling it has changed. If your worry is that any of this will read as manufactured, the mechanism and the naming test are in can sensory branding modernise a legacy business without making it feel artificial. And if the refit is happening because a new generation has taken over, the discipline for changing a smell as well as the interiors is in should the next generation change the store's smell as well as its interiors and branding.

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.
