So the register matters, and the honest answer is a quiet tea-based one held low. But the thing that separates a consultation room that feels expensive from one that does not is timing. A room that has been running a low steady source since you opened smells settled, and settled reads as a place. A room that has been sprayed, wiped down and switched on five minutes before the doorbell smells prepared, and prepared reads as staged. People are surprisingly good at telling those two apart even when they could not describe the difference, because a spray is a peak that is already decaying and a steady low source is a flat line. A peak says something just happened here. A flat line says this is how it always is.
The second thing that makes a consultation different from a walk-in is that your visitors arrive with their own air on them. On a hot afternoon in Chennai or Delhi, a personal fragrance projects more from warm skin than it does from cool. In monsoon they arrive with a wet umbrella and a damp jacket. In a Delhi winter they arrive out of a closed-up car into a closed-up building. All of that is in the room within a minute of them sitting down, and your register has to be quiet enough to live underneath it rather than argue with it.
This page is therefore about the appointment rather than the bottle: what to do in the half hour before they arrive, what not to do while they are sitting there, and how to run back-to-back Saturdays without the fourth couple of the day walking into a room that has held eleven people since ten in the morning.
Should I spray or freshen the room just before clients arrive? No. A room sprayed five minutes before an arrival smells like a peak that is already decaying, and people read that as staged. A room running one low steady source since morning reads as settled, which is what you actually want. Prepare the room - air it, clear it, reset it - thirty minutes before they arrive, and then let it be.
What about the couple's own perfume? Assume they are wearing something and that it will project more if they have come in warm from outside. That is one more reason to run the room low enough to sit underneath a personal fragrance rather than beside it. In a small consultation room with three or four people in it, your register is the least important smell present, and it should behave that way.
Which means two things. First, set the level for the doorway, not for the middle of the room and certainly not for how it feels to you at four in the afternoon. Second, everything you do to the room after they arrive is either invisible or intrusive - there is no useful middle. Adding scent while a client is in the room is not a top-up, it is an event, and they will notice the event.
Now the timing. The room should have been running one low steady source since you opened, so that it is at a settled, flat, unremarkable level by the time anybody arrives. The preparation - opening windows, running extraction, taking out cups and flowers, wiping the table, putting the covers straight - should happen thirty minutes before, so the room has time to become itself again. What must not happen is a burst of activity in the last five minutes: a spray, a candle lit as they climb the stairs, a strong cleaning product used on the album table, a diffuser turned up because it "isn't coming through". Every one of those produces a peak, and a peak is exactly what makes a room read as staged rather than as a place. A couple cannot tell you why the room felt as though it had been got ready for them, but they can tell that it was.
Then the room they are walking into has to hold what they bring. Two or three people arrive with their own fragrance on them, and on a warm day it projects more than it would have done in an air-conditioned office. They bring wet umbrellas in July and coats in January. They bring coffee. Within a few minutes the room's air is theirs, not yours, and that is correct - your register's job at that point is to be the quiet floor underneath it all. A room set low enough to sit under a client's own perfume is the right target, and in bridal work that is not merely good manners: a bride may be trialling a fragrance for the wedding day and paying close attention to it, and a studio that competes with that has intruded on something that is hers.
And of course, none of this works if the underlying air is not honest, because fragrance adds scent and does not remove odour. A room that has held eleven people since ten in the morning, with tea and a bin and the door shut, cannot be fixed at five to three with anything in a bottle. It is fixed with ten minutes of open door and moving air. Source, then ventilation, then cleaning, then fragrance - and on a busy Saturday the middle two are the whole job. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The clearest way to feel the difference is to notice it somewhere else. You know instantly when a hotel corridor has just been sprayed rather than being a corridor that always smells like that, and the knowledge is not flattering to the hotel. It is the same signal in a studio, and it is louder in a small consultation room than in a lobby because there is less air to dilute the peak.
There is a second, subtler reason to run steady rather than to freshen. Human noses are change detectors. They report differences and then stop reporting. A steady low source presents no change once somebody is inside, so it drops out of awareness within minutes and stays out for the whole appointment, which is exactly what you want across three or four hours. A burst presents a change, gets reported, and then decays - which means it is at its loudest in the first ten minutes, when the couple are most alert to the room, and it is fading by the time they have settled. That is precisely backwards.
The third reason is the one that costs you if you ignore it: on a Saturday you are not running one appointment, you are running four. If your approach to each one is to freshen the room beforehand, by the third arrival you are laying a peak on top of a peak on top of three hours of people, and the fourth couple gets the accumulated total. A steady low source plus ten minutes of open door between appointments gives every couple the same room, which is the whole point.
The consultation as an event - arrival, the first breath, and the hours after it
A consultation is not a room, it is a sequence, and each stage of it has a different requirement.
There is the approach, which is the street, the stairs or the lift and the last thirty seconds before your door. There is the threshold, which is one breath and the only clean reading anyone will take. There is the settling, ten or fifteen minutes of coats, handbags, tea and small talk while people adapt. And there is the long middle, two to five hours of concentration in which the air should be doing absolutely nothing. Almost all the fragrance advice in this trade is written as though only the threshold existed, which is why so many studios are set to a level that is charming for ninety seconds and tiring by hour two.
Two facts about noses run underneath all of it. The first is adaptation: everybody stops noticing a steady smell within minutes, including your clients, including you, and this is why the level must be set for the arrival rather than for the occupied room. The second is that noses report change more than they report state. That single fact is why a steady source and a burst of the same fragrance are experienced completely differently even if the total quantity is similar - and why "run it low all day" beats "give it a boost before they come" every time.
There is also a practical variable that is specific to India and that changes what walks through your door. In Mumbai or Goa in monsoon, people arrive damp and so does everything they are carrying, and a room with a lot of textile in it will hold that. In Delhi in January they arrive from a closed car into a closed building where nothing has been aired since the cold started. In Chennai or Hyderabad in May they arrive warm, and warm skin projects a personal fragrance further than cool skin does. None of this changes the register you have chosen. All of it changes how much airing the room needs before the appointment, which is a free adjustment you make with a door rather than a dial.
Here is the exercise. Leave the building. Walk around the block, or sit in the car with the window down, for a quarter of an hour. Come back and stop in the doorway. Do not walk in. Take one breath and write down, in plain words, what you get. "Nothing." "Cool." "Tea." "Shut." "Cardboard." "Strong." Whatever the word is, that is what a couple gets, and it is formed before they have said hello.
Then repeat it at the second threshold, which most studios forget: the door of the consultation room itself. A couple crosses two boundaries, not one, and the second crossing happens after they have already adapted to your reception. If reception is running at a level they have settled into, and the consultation room is running at the same level behind a shut door, the second reading will be higher than the first, because a closed room accumulates. Which is precisely why the long-dwell room should be running lower than reception, not equal to it.
Do the arithmetic on the room they are heading into, because it explains the accumulation. A 220 sq ft consultation room at 9 ft is 220 x 9 = 1,980 cu ft, and 1,980 / 35.3 is about 56 m3. A 300 sq ft one at 10 ft is 3,000 cu ft, about 85 m3. Compare that with the reception and waiting area they just walked through: 400 sq ft at 12 ft is 4,800 cu ft, about 136 m3. The room they will sit in for three hours is often the smallest air volume in the building, and the door will be shut on it.
A last note on the approach, which is free and which studios in shared buildings underrate. If your studio is on the second floor of an office building, your clients have just walked through somebody else's air - a lift, a stairwell, a corridor with somebody else's cleaning products in it. Their nose has been reset by whatever that was. You cannot control it, but you can be aware that a strongly perfumed common stairwell means your own quiet doorway will read as clean and welcome rather than as underwhelming, and that a neutral corridor means your doorway is being judged against nothing at all.
And if the honest word you wrote down at the door was "strong", the fix is the dial rather than the register, and the direction is down. If two out of three visitors can name a product from the doorway, you are not running an atmosphere, you are running an air freshener - and in a room where somebody is about to commit a large sum to you, that is a small argument against your prices being played on a loop.
The instinct is: a couple are coming at eleven, so at ten to eleven I will make the room nice. Spray something, light something, turn the diffuser up, wipe the table with a scented cleaner. It feels like hospitality. What it actually produces is a peak - a concentration that is at its highest right now and will fall away over the next hour - and a peak is legible. People know what a just-sprayed room smells like because they have all met one in a lift, a showroom, a rented flat or a hotel corridor. The signal it sends is not "this is a lovely place". It is "something was done here just before I arrived", and in a business built on trust that is an odd note to open on.
A low steady source produces the opposite signal, because it produces no signal at all. It is a flat line. There is nothing to notice, nothing decaying, nothing that changes across the appointment. The room simply has a character, the way a room with good light has a character, and nobody asks when the light was switched on. That is what "settled" means, and it is why the studios that smell most expensive are almost always the ones running the lowest, steadiest level in the building.
There is a physical version of the same tell that has nothing to do with fragrance and everything to do with how the room is read. Cushions plumped and set at forty-five degrees, a fan of brochures on a table, the chair pushed in at a perfect angle: all of these are peaks too, and they say staged in exactly the way a spray does. A room that looks and smells lived in but immaculate reads as a working studio that is always like this. That is a higher-status impression than a room that has clearly been dressed, and it is cheaper to produce.
So the practical rule is: everything you do to the room, do it early enough that it has stopped being a change by the time they arrive. Thirty minutes is a good default. Air, clear, wipe, straighten, take the bin out, take yesterday's flowers out, then leave the room alone. If you use a cleaning product with any real perfume on it, use it at opening rather than before an appointment, or switch to one that does not announce itself - a strongly scented floor cleaner is a fragrance decision you did not know you were making and it is usually louder than your diffuser.
Two more things not to do while people are seated. Do not light a candle mid-meeting; it is a change and it is also a new smell layered onto an occupied room. And do not turn the machine up because it "isn't coming through" - by hour two everybody in that room, including you, has adapted, and turning it up simply means the level is wrong for the next couple who arrive with a clean nose.
The one thing you should do mid-appointment is open the door for a couple of minutes when you break, if the room has a door that can be opened onto something. That is not a fragrance action. It is the reset that makes hours three and four feel like hour one.
There is a version of the staged tell that catches out studios who are otherwise doing everything right, and it is the loo. A client excuses themselves an hour into the appointment, opens a door and gets a completely different smell from the one they have settled into - usually something strong, usually covering an extraction problem. That is a peak too, and it lands in the middle of the appointment when they are most relaxed. The fix is the extraction and the cleaning, and then one quiet reed in there that is a softer version of your client route rather than a different register announcing itself. A studio whose loo smells like a quieter version of its reception feels like one building. A studio whose loo smells like a supermarket aisle undoes an hour of careful work in four seconds.
At opening. Open every client room. Doors, windows if you have them, extraction if you have it. Ten to fifteen minutes of moving air in each. Take out anything from yesterday: cups, the bin, flowers that have turned, packaging. Then switch on the one low steady source you run - a machine on a timer, or a reed that was already there and never gets switched on at all - and let the building settle. If your machine has an app and a timer, as the Vaayu does, this step is a schedule you set once rather than a decision you make daily, which is exactly why the timer is worth more than it sounds.
Thirty minutes before the appointment. Reset the consultation room. Straighten, wipe, empty, air. If it needs a cleaning product, use it now rather than in ten minutes. Put the tea things where they will be used. Then close the loop and leave the room alone, so that by the time the doorbell goes, nothing in there is a recent event.
At the arrival. Nothing. No spray, no candle, no adjustment. Take the coats, offer somewhere for a handbag, and let the room do what it has been doing since morning.
During. Nothing to the air except opening the door for two minutes at a natural break. Serve tea and food at a planned moment rather than continuously, because food is a genuine smell event in a small closed room and it is far better as one clean interruption than as a drift of it for three hours. And take the cups and plates out of the room when the break ends rather than letting them sit on the album table until five.
Between back-to-back appointments. Ten minutes with the door open and, if you have it, extraction running. This is the single highest-value habit on the page for anyone shooting a full wedding season, because your fourth couple of the day should get the same room your first one did. They will not, unless somebody makes it happen. A room that has held four people for three hours holds their afternoon, and no register conceals that - fragrance adds scent and does not remove odour. Ten minutes of air does more for the four o'clock appointment than anything you could buy.
At close. Take everything out. Cups, food, flowers if they are done, the bin, wet umbrellas in monsoon. A room that is emptied at seven starts clean at ten; a room that is emptied at ten in the morning has already lost the first appointment.
One thing that is never part of the run sheet, in any phrasing: reducing ventilation, closing vents or shutting off extraction so the fragrance lasts longer. A well-aired studio is genuinely harder to scent and that is a good problem. You solve it with a sensible level and placement, not by keeping the air still - and in a room where four people are going to sit for four hours, still air is the last thing you want.
And your staff, as always, are the check on the whole thing. They are in that air for eight to ten hours a day, five or six days a week, while a couple gets four hours twice. If an assistant or an album designer mentions the scent, that is a recalibration signal and not a tolerance problem: turn it down first, discuss it second.
- Air every client room at opening, then start one low steady source and leave it.
- Reset the consultation room thirty minutes before they arrive, not five.
- Never spray, light or adjust anything in a room a client is about to enter.
- Give back-to-back appointments ten minutes of open door and moving air between.
The register for a consultation, and the timing that matters more than it
With the timing settled, the register is a short conversation. What a consultation needs is something quiet, socially agreeable and capable of being ignored for four hours, and three of the seven water-based Hotel Collection registers do that particularly well. Each is SOSA's own hotel-inspired interpretation; SOSA is independent and is not affiliated with, endorsed by or connected to any hotel brand.
Quiet Luxury - white tea, bergamot, cedar. Hushed, polished lobby calm, and the widest social range of the seven, which is what a consultation actually requires, because the room may hold a bride, a groom who is present out of duty, a mother with firm views and a father-in-law thinking about the total. It reads as considered to all of them and as a fragrance choice to none of them.
Tea Garden - jasmine, green tea, white tea. Serene tea-and-jasmine calm, and the soft answer when the room itself is bridal. It is the floral that behaves across long appointments because the jasmine sits inside the tea rather than on top of it. Run it a step lower than a tea or a wood, because a floral at an identical setting always reads as more, and remember that a bride may be wearing jasmine herself.
White Tea Serenity - white tea, aloe, cedar. Clean, weightless, spa-like, and the most transparent thing in the collection. If your consultation room is small - and a 220 sq ft room at 9 ft is about 56 m3, which is not much air for four people and three hours - transparency is a technical virtue rather than a timid choice.
Warm Welcome - citrus, floral, sandalwood - is a threshold register, and it is a good one at your front door in a warm family-facing practice. In the closed consultation room over several hours the sandalwood carries more weight than a long sitting wants, so if you love it, use it at the entrance and run something cooler behind the door - accepting that this is one of the few cases where two levels of two characters is worth the seam. Of the remaining three, Forest Suite (cedarwood, vetiver, green leaves) belongs in a concrete-and-plants studio, Old-World Glamour (amber, violet, woods) is plush and evening-elegant and better suited to forty minutes in a dark portrait corner than to four hours at an album table, and Lobby Bar (citrus, pepper, amber) is bold and after-dark and louder than the conversation you are trying to have.
I will not rank any of them against each other on throw or longevity, because SOSA does not publish that comparison and because in a small closed room the things that decide how strong it feels - your setting, the ventilation, the amount of textile, the number of people and how long the door has been shut - swamp any difference between one blend and another. And I will not invent a note; the ones above are the published ones.
Two things that belong to a consultation specifically. The first is tea and food. In a three-hour appointment somebody will eat something, and food in a small closed room is a bigger smell event than anything in your diffuser. Plan it as one clean interruption at a natural break rather than letting it drift through the afternoon, and take the plates out of the room when the break ends. The second is flowers. Many bridal studios keep fresh flowers in the consultation room, and they are lovely, but they are already a floral. Real jasmine or tuberose plus a floral register in 56 m3 is the commonest way this room goes wrong. Choose the flowers or choose the register, and if you keep the flowers, take them out the day they turn rather than the day they die.
And one thing that overrides everything on this page: if a bride, a mother or anyone else in the room says they would rather the fragrance was not there, switch it off. Do not explain that it is very low. Do not offer to open a window instead. Switch it off, and remember it for their next appointment. A client's own preference beats every sentence written here, and being the studio that did that without a discussion is worth considerably more than any register.
| Scent | Why it suits the mood |
|---|---|
| At the threshold · one breath, clean nose | The only honest reading anyone takes. Set the level here, from the doorway, with a nose that has been outside for fifteen minutes - never from the middle of the room in the afternoon. Quiet Luxury carries a threshold well because it reads as lobby calm rather than as fragrance. |
| Thirty minutes before · the preparation window | Air, clear, wipe, straighten, empty the bin, use any cleaning product now rather than later. Then close the loop and leave the room alone so nothing in it is a recent event by the time the doorbell goes. This is what makes the room read as settled rather than staged. |
| The long middle · two to five hours | Nothing at all to the air except opening the door for two minutes at a natural break. No spray, no candle, no turning it up because it seems to have faded - by hour two everyone in the room has adapted, including you. Tea Garden or White Tea Serenity, run lower here than at the door. |
| Between appointments · ten minutes of moving air | The highest-value habit in a busy wedding season. A room that has held four people for three hours holds their afternoon, and fragrance adds scent rather than removing odour. Open the door, run any extraction, take the cups and plates out, and let the fourth couple of the day get the same room the first one did. |
What to buy for a consultation-led practice follows from the routine rather than from the register.
The single most useful feature for this page's argument is a timer, because the whole method is "steady from opening, untouched during, off when the building is empty". The SOSA Vaayu at ₹11,999 has a Bluetooth app and timer, which turns the routine into a schedule you set once rather than a decision you make on a busy Saturday. It is waterless cold-air nebulising of undiluted oil - no water, no humidity, no wet residue - rated for approximately 1000 m3 of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. It takes a 400ml tank, mounts freestanding, on a wall or into HVAC, runs on DC 12V / 1A at 5W so it needs a live socket, and carries CE, RoHS and SGS. It belongs on the connected client route - reception, waiting area, corridor - rather than inside a small consultation room, because a shut door ends one volume and begins another.
For the consultation room itself, smaller is better and steadier is better still. A SOSA reed diffuser from ₹749 is the purest version of "settled": no plug, no timer, nothing to switch on when the doorbell goes, and therefore nothing that can produce a peak. Morning Freshness ₹749 is Malabar lemon, mint and eucalyptus; Garden Bloom ₹799 is British rose and night-blooming jasmine; Evening Calm ₹799 is Kashmir lavender and chamomile; Mountain Breeze ₹849 is Himalayan pine, sage and cedar; Fresh Brew ₹849 is Coorg coffee and Kerala vanilla, which I would keep out of a room where two people sit for four hours. They last about 6 to 10 weeks, the 130ml is from ₹1,249 and refills are ₹2,399 for 300ml and ₹3,499 for 500ml. The reed set is also worth knowing about because Morning Freshness in a client loo, kept quiet, is a better solution than anything that plugs in.
If you want a Hotel Collection register in the consultation room to match the client route, a SOSA Boond at ₹899 on its lowest setting running the water-based Hotel Collection from ₹299 is the honest size, with 100ml refills at ₹999 and a seven-bottle 15ml pack at ₹1,799 for trying registers in your own air. A Sukoon at ₹1,899 is a reception machine; a Megh at ₹3,499 with its 6 litre tank suits a large lounge running from ten to eight through the season without a refill in the middle of an appointment, which is itself a timing benefit.
Two systems, and they are not interchangeable. The ultrasonics are water-based cool-mist machines that put moisture into the air; the Vaayu and the ducted 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. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. And wherever a machine ends up, ordinary studio prudence applies: away from open equipment cases and from the spot where lenses get changed, and never point a mist machine at anything you care about. That is housekeeping, not a protection claim, and SOSA publishes none.
For the rest of the argument: the room-by-room map is what a luxury wedding photography studio should smell like; the register decision for a client-facing wedding practice is the best fragrance for a premium wedding photographer's client studio; and if the room you are worried about is small and closed, with the arithmetic done properly, read what a bridal photography consultation lounge should smell like. If your question is really about the whole impression rather than the air, how to make a wedding photography studio feel more luxurious is mostly about airing, laundry and taking things out of the room.
What SOSA does not publish, and this page will not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order or lead time. Those follow from run hours, connected volume and setting, all of which are yours rather than ours. Send your consultation-day schedule, the room dimensions and the ceiling height to SOSA on WhatsApp at +91 96192 18531 and you will get a level and a timing plan rather than a catalogue. Bulk orders are welcome, custom label or logo on product is available, and a bespoke composition made only for your studio is a real SOSA service discussed there rather than priced on a page.
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 - 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 photography studio sells a feeling before it sells a photograph. A couple sitting on your sofa choosing an album is doing something emotional, and they are doing it in your air for three or four hours. That is a long time to be in a room, and it is the reason I keep telling studio owners to go lower than they think.
The mistake I see is scenting the whole studio at one level. A reception is a thirty-second room and can carry a little presence. A consultation lounge is a three-hour room and needs a whisper. A newborn or maternity room should usually have nothing at all, and I would rather say that plainly than sell a second machine.
And the unglamorous part first: fragrance adds scent, it does not remove odour. If the studio smells of hairspray, of last night's crew dinner or of a room that has been shut since Sunday, scent laid on top makes a third smell. Find the source, air the room, clean it - and then, when the air is honest, give it a signature.
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. 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.
