But the reason it is the right answer is more useful than the answer. A register is an aesthetic choice, like the colour you painted the reception wall. It is real, it matters, and it is also the part of this decision that is hardest to get badly wrong. What goes wrong in studios is not register. It is level. I have walked into perhaps two studios in my life where the fragrance was simply the wrong character for the space, and dozens where a perfectly reasonable fragrance was running at two or three times what a seated client can take for four hours.
So this page does two things. It maps all seven Hotel Collection registers honestly onto the kinds of photography studio that actually exist - bridal, fashion, portrait, corporate headshot, editorial, family - and then it spends just as long on the thing that will actually decide whether your studio smells expensive or cheap, which is how much of it you run and in which room.
Which register lasts longest or throws furthest? SOSA does not publish comparative throw or longevity figures for the seven registers and this page will not invent them. What actually decides how a register behaves in your studio is the connected air volume, the ceiling height, the ventilation rate, how much soft material is in the room and what level you set. Two registers in the same room at the same setting are far more alike than the internet suggests.
Does the register matter more than the machine? Neither matters as much as the level. Register is taste; level is what goes wrong. Choose a register that agrees with your materials and light, then set it low enough that a client sitting for four hours never thinks about it - a Sukoon at ₹1,899 for one room, a Vaayu at ₹11,999 for a connected floor.
If none of that resonates, run Quiet Luxury. It is the default for a reason. White tea, bergamot and cedar reads as hushed, polished lobby calm, which is precisely the register a photography studio's reception is trying to achieve anyway, and it is neutral enough that a bride, a CEO having a headshot done and a fashion crew will all find it unobjectionable. Unobjectionable is not a criticism in commercial scenting. It is the whole target.
Now the part that will actually change your outcome. Whichever of those you choose, the level is not one level. Reception is a thirty-second room and can carry a little presence. The consultation lounge, the bridal room and the album-selection room are three-to-six-hour rooms and take the lowest dose in the building. The makeup and styling area already has hairspray and setting spray winning in it, so adding a register there makes a third smell rather than a blend - usually, leave it. And the shooting sets are not the opportunity: the client route is. Reception, consultation, bridal and client lounges and waiting areas are where this money does its work.
One more honest thing, because it saves people money. If your studio currently smells of anything - stale air, damp, fabric, last night's crew dinner - no register on this list will help, because fragrance adds scent and does not remove odour. Source, then ventilation, then cleaning, then fragrance. Get the air honest first and you will need less of whatever you buy.
And a note on how to test, because this is the one place I would spend a little money before spending a lot. The pack of seven 15ml Hotel Collection bottles at ₹1,799 exists precisely so that you can try registers in your own room instead of choosing from a description written by somebody who has never seen it. Run each one for several days in your actual reception at a low setting, and judge it on day five rather than on the first afternoon. A portion of every SOSA order supports girl-child education through Nanhi Kali.
And please do not choose by reading note lists on a phone. Notes are how a perfumer describes an intention, not how a register behaves in a 12 ft-ceilinged room in Pune in August with the AC on. Choose by looking at your own walls.
The commonest way this decision goes wrong is a studio owner picking the register they would wear. A personal fragrance is meant to be noticed at conversational distance by one person at a time; a room register is meant to be unnoticed by fourteen people at once, several of whom are already wearing something. They are different crafts with different targets, and the register you would love on your wrist is very often the one that makes your reception feel like it is trying too hard.
What actually decides the register - and what only looks like it does
Three things genuinely decide which register belongs in a photography studio, and none of them is the note list. The first is the material and light of the space itself - a register either agrees with the room or quietly argues with it, and clients feel the argument without being able to name it. The second is whose fragrance is already in the air, which in this vertical is a bigger factor than in any other commercial space I work in, because your clients arrive wearing perfume and your makeup room arrives wearing hairspray. The third is the register's job description in each room, which changes with dwell time.
What does not decide it is any comparison of throw or longevity between the seven, because those are not published, they are not stable across rooms, and any page that ranks them is guessing. The same register in a 300 sq ft room at 10 ft - 300 x 10 = 3,000 cu ft, about 85 m3 - behaves completely differently from the same register in a 1,500 sq ft floor at 14 ft, which is 21,000 cu ft, about 595 m3. Volume, ventilation, soft material and setting swamp any inherent difference between one blend and another. So this page will map character to space, and will refuse to tell you which one is strongest, because nobody honestly knows that about your room but you.
It is also worth being clear about what "luxury" means in this question, because the word is doing a lot of unexamined work. A luxury photography studio is not a studio with an expensive scent in it. It is a studio where every small thing has been decided rather than defaulted - the chair the client sits in, the temperature, the tea, the light in the loo, the length of the wait, and yes, the air. Fragrance is one of the cheapest of those decisions and one of the easiest to get showily wrong, which is why the luxury version of the decision is almost always the restrained one. If a visitor can identify your fragrance as a product from the doorway, the room has told them you bought something. If they cannot, it has told them you thought about something.
Run through it concretely. A pale, daylight-flooded studio with linen curtains, white cyclorama and light wood is a cool, clean, weightless room: White Tea Serenity - white tea, aloe, cedar - is that room in a bottle, and Quiet Luxury is the slightly more polished version of the same idea. A converted industrial unit with polished concrete, black frames, large plants and exposed ductwork is a green, grounded, structural room: Forest Suite - cedarwood, vetiver, green leaves - agrees with it, and it is also the register most likely to read as neutral to a mixed crew rather than as a floral choice somebody made.
A bridal or wedding studio, typically ivory, gold, soft furnishing, flowers and a lot of fabric: Tea Garden - jasmine, green tea, white tea - is the floral that behaves, because the jasmine sits inside the tea rather than sitting on top of it. A dark, low-lit portrait or fine-art room with velvet, deep paint and brass: Old-World Glamour - amber, violet, woods - is plush and evening-elegant and it belongs there, with the caveat that plush is a lot at hour four, so it is a portrait-room register rather than an album-room register.
Two more. Warm Welcome - citrus, floral, sandalwood - is a threshold register: gracious rather than cool, and the right choice if your studio's whole positioning is warmth, family and hospitality rather than editorial restraint. Lobby Bar - citrus, pepper, amber - is bold, playful and after-dark, and in this vertical it has exactly one home: a studio that hosts evening events, launches or content shoots for nightlife and beverage brands. In a daytime portrait studio it is simply louder than the work.
There is a fourth kind of studio that does not fit any of those descriptions, and it is very common in India: the multi-purpose floor. Weddings on Saturday, corporate headshots on Tuesday, a product table in the corner, an events booking once a month. If that is you, do not try to match the register to the work, because the work changes every day and the register cannot. Match it to the reception, which is the one room every client passes through, and let that single decision carry the building. This is the strongest argument for Quiet Luxury: it is the register least likely to feel wrong to whoever happens to be booked in that day.
One more test that costs nothing. Whatever register you are leaning towards, imagine describing it out loud to a client who asks. If the honest sentence is "it's just how the studio smells", you have chosen well. If the honest sentence is "it's vanilla and sandalwood, do you like it?", you have chosen a product rather than an atmosphere, and the level is almost certainly too high as well.
That single fact argues for two things. It argues for a quiet register rather than a loud one, and it argues even harder for a low level, because a low level of almost anything sits underneath a personal fragrance rather than fighting it. It is also the strongest practical case for the tea-and-white-tea family in a bridal studio: Tea Garden and Quiet Luxury are both built around tea, which is about as socially agreeable as fragrance gets and which does not lay a competing floral over somebody's own jasmine.
Then the makeup and styling area, which is a different problem. By ten in the morning that corner contains hairspray, setting spray, primer, a hot tool and somebody's perfume. Those are strong volatiles and they are winning; a diffuser added on top does not blend with them, it produces a third smell that belongs to nobody. The honest move is to leave the styling area unscented, treat its smell as a ventilation and cleaning job, and keep the door shut so it does not become the register your client route is actually running.
The same logic covers the changing room, the loo and the equipment store. None of those are fragrance opportunities. They are extraction, laundry and housekeeping opportunities, and a studio that gets them right needs less fragrance everywhere else.
There is a version of this problem that only shows up on busy days. Fourteen people in a 500 sq ft lounge at 12 ft - that is 6,000 cu ft, roughly 170 m3 - is a lot of bodies, coats, bags, coffee and personal fragrance in a small amount of air, and by hour three the room smells of the day rather than of your register. The temptation on that afternoon is to turn the machine up. Do not. The fix is air and space: get the door open between sittings, run the extraction, take the cups out, and let the room reset. Turning the level up on a full room simply means that when the room empties at six, the level is wrong for everybody who arrives tomorrow.
Which is why the register you can live with is more valuable than the register you love on the first sniff. Ask yourself which of the seven you would still be content to smell in your own reception every working day for a year, at a level so low you barely notice it. That question eliminates the exciting answers quickly, and eliminating the exciting answers is usually the right outcome in a commercial space.
So the working method is: choose the register in twenty minutes using the room-agrees-with-register logic above, set the level at what feels almost too little on day one, and then do not touch it for two weeks. Judge it from the doorway on a morning the building has been shut, not from the middle of the room at 4pm on a shoot day. Ask three people who have just come in off the street, before you tell them there is a diffuser running. If nobody mentions it and nobody is bothered, you are approximately right. If two of them name a product, come down.
Your staff are the other check, and they matter more than any of this. They are in that air for eight to ten hours a day, five or six days a week, while a client gets three hours twice a year. If an assistant, a retoucher or a makeup artist mentions the scent, that is a recalibration signal and not a tolerance problem. Turn it down first, discuss it second.
And the thing that is never the answer: do not reduce your ventilation so the fragrance lasts longer. A well-ventilated studio is genuinely harder to scent, which is a good problem to have. You solve it with placement, with a machine sized to the connected volume and with a sensible setting - never by closing a vent, shutting off extraction or leaving a room to go stale.
It is worth naming the specific way this failure looks, because owners describe it to me in the same words every time. "It was perfect for the first week and then it faded." Almost always, it did not fade. The nose of the person judging it adapted, and the level that was correct on day one now reads as nothing to the one human being in the building who is exposed to it most. The correct response to "it faded" is to ask somebody who has not been in the room, not to reach for the dial. If three visitors in a row also say they cannot smell anything, then you have a genuine level problem and you can move it up one notch - once, and then leave it for another fortnight.
The other failure mode is seasonal drift. A studio in Pune in February with the doors open behaves differently from the same studio in May with the AC running hard and the doors shut, and differently again in August when everything textile in the building is holding monsoon damp. Expect to make two small level adjustments a year, not two a week, and make them deliberately rather than in reaction to one bad afternoon.
- Stand in reception in daylight and name what the materials are already saying.
- Pick ONE register for the whole client route. Not one per room.
- Set it low, then judge it from the doorway on a morning the studio has been shut.
- Leave it untouched for two weeks before you decide anything at all.
The seven registers, and the kind of studio each one belongs in
Here are all seven, mapped to real studios. Each is SOSA's own hotel-inspired interpretation - SOSA is independent and is not affiliated with, endorsed by or connected to any hotel brand, and the hotel names below describe an inspiration rather than a licence.
Quiet Luxury (Ritz-Carlton-inspired) - white tea, bergamot, cedar. Hushed, polished lobby calm. This is the default answer for a luxury photography studio and the register I recommend when an owner has no strong view, because it does the job of a good reception without announcing itself: the room feels considered and nobody can tell you why. It is neutral across client types, which matters when the same reception holds a bride at eleven and a corporate headshot client at three. If you run one register on the whole client route - and most studios should - this is the one to run.
White Tea Serenity (Westin-inspired) - white tea, aloe, cedar. Clean, weightless, spa-like. The right answer for the pale, minimal, daylight-heavy studio: white cyclorama, linen, light oak, big windows. It is the coolest and most transparent of the seven and it is very hard to over-notice, which makes it a good choice for a studio whose whole aesthetic is restraint. It is also the register I would pick for a headshot or personal-brand studio where clients come in nervous about being photographed and the room's job is to feel uncomplicated.
Forest Suite (1 Hotels-inspired) - cedarwood, vetiver, green leaves. Grounding, biophilic green. This is the industrial studio's register: concrete, steel, plants, dark timber, a warehouse shell, a double-height bay. It reads as structural rather than decorative and it is the one register in the collection that a mixed crew of camera assistants, stylists and clients will all read as neutral rather than as somebody's floral choice. It also sits comfortably in a studio that shoots a lot of menswear, product or automotive work.
Tea Garden (Shangri-La-inspired) - jasmine, green tea, white tea. Serene tea-and-jasmine calm. The bridal answer, and the best floral in the collection for long-dwell rooms, because the jasmine is held inside tea rather than sitting on top of it. A wedding consultation or album-selection room is a three-to-six-hour room and most florals become tiring in it; this one is built to stay quiet. Run it lower here than anywhere else in the building, and remember the bride may be wearing her own.
Warm Welcome (Four Seasons-inspired) - citrus, floral, sandalwood. Warm, gracious hospitality. A threshold register for a studio whose positioning is warmth rather than editorial cool - family portraiture, milestone photography, a studio in a converted home, a practice where the receptionist knows everybody's name. The sandalwood gives it enough weight to feel like a real welcome rather than a citrus spritz, and the citrus keeps it from feeling heavy at the door.
Old-World Glamour (St. Regis-inspired) - amber, violet, woods. Plush, evening-elegant. The dark portrait room, the fine-art studio, the space with deep paint, velvet, brass and controlled low light. It is the most characterful register here and it is the one that most rewards a low setting, because plush at a high level becomes heavy quickly. My standing advice is that it belongs in the room where people are photographed for forty minutes rather than the room where they sit for four hours.
Lobby Bar (W Hotels-inspired) - citrus, pepper, amber. Bold, playful, after-dark. In a photography studio it has one legitimate home: a space that hosts evening events, launches, brand parties or nightlife-adjacent content. It is the loudest of the seven in character and it will feel like a lot in a daytime portrait studio. If you host events monthly and shoot portraits weekly, run your normal register and let the events borrow the room rather than the other way round.
What I will not do is rank those seven against each other on throw or longevity. SOSA does not publish that comparison, no honest supplier can give you one that survives contact with your particular room, and the variables that dominate - connected volume, ceiling height, ventilation rate, soft furnishing, setting, run hours - are all yours. Anyone who tells you register A "lasts twice as long" as register B in a studio they have never stood in is guessing at your expense.
What I will happily give you is a shortlist by client type, which is a more honest way to narrow seven down to two. Wedding and bridal: Tea Garden or Quiet Luxury. Fashion and editorial: Forest Suite or Quiet Luxury. Corporate headshots and personal branding: White Tea Serenity or Quiet Luxury. Family, milestone and newborn reception areas, with the rooms themselves left alone: Warm Welcome or White Tea Serenity. Fine-art and dark portraiture: Old-World Glamour in the portrait room, Quiet Luxury on the route. Event and nightlife content: Lobby Bar for the events, your normal register the rest of the time. You will notice Quiet Luxury appears in five of six lines, which is not laziness - it is the answer.
The practical way to close this out is the ₹1,799 pack of seven 15ml bottles. Run one register per week in your actual reception, at a low setting, and pay attention to how you feel about it on day five rather than on the first afternoon. First impressions in fragrance are unreliable and day-five impressions are excellent. Most studios discover that the register they were most excited about is the one they are most tired of, and that the quiet one they nearly dismissed is the one they want to keep for a year.
And the rooms that get no register at all, in any studio, at any price: the active shooting sets, the makeup and styling station, the equipment store, and a newborn photography room, which should be fragrance-free without hedging. Pregnant clients are commonly scent-sensitive and nausea is ordinary in pregnancy, which is a plain reason to keep those rooms unscented; it is not a basis for any health, safety or calming claim in either direction, and this page makes none. The client's own preference overrides everything written here.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · the default | White tea, bergamot and cedar. Ritz-Carlton-inspired, SOSA's own interpretation. The right answer for the largest number of luxury studios because it is neutral across client types - the same reception can hold a bride at eleven and a corporate headshot at three. Hushed, polished, hard to dislike. |
| Tea Garden · bridal and wedding | Jasmine, green tea and white tea. Shangri-La-inspired. The floral that behaves in a long-dwell room, because the jasmine sits inside tea rather than on top of it. Run it lower in a consultation or album room than anywhere else, and never at a level that competes with the bride's own fragrance. |
| Forest Suite · industrial and green | Cedarwood, vetiver and green leaves. 1 Hotels-inspired. For concrete, steel, plants, dark timber and warehouse volumes. The register a mixed crew reads as neutral rather than as somebody's floral choice, and a natural fit for menswear, product and automotive work. It is also the one that suits a double-height bay, where the volume is large and the register needs to feel structural rather than decorative. |
| Old-World Glamour · dark portrait rooms | Amber, violet and woods. St. Regis-inspired. Plush and evening-elegant, for deep paint, velvet, brass and controlled low light. The register that most rewards a low setting - it belongs in the room where somebody is photographed for forty minutes, not the room where they sit for four hours. |
Once the register is chosen, the buying question is settled by connected air volume rather than by register, because every one of the seven runs on the same machines. For one reception or one consultation room, an ultrasonic is enough: the SOSA Boond at ₹899 for a small enclosed room, or the SOSA Sukoon at ₹1,899 for a normal reception, both running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999. A pack of seven 15ml bottles at ₹1,799 is the sensible way to try registers in your own room rather than deciding from a description on a page - and trying them in your own air is genuinely the only test that means anything. If your lounge runs all day, the SOSA Megh at ₹3,499 and its 6 litre tank saves you refilling at lunchtime.
For a whole connected client route - reception, corridor and lounge open to each other - the SOSA Vaayu at ₹11,999 is the commercial machine: waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue. It is rated for approximately 1000 m3 of connected air, and SOSA's own copy also states 2,000 to 3,000 sq ft scented evenly. Do the arithmetic on your own space before you decide: a 500 sq ft reception and lounge at 12 ft is 6,000 cu ft, about 170 m3; a 1,000 sq ft floor at 12 ft is 12,000 cu ft, about 340 m3; a 2,000 sq ft floor at 14 ft is 28,000 cu ft, about 793 m3. All three of those sit inside one Vaayu's rating if the air is genuinely connected. A shut door ends one volume and begins another, and no register changes that.
The Vaayu's practical details matter more than its rating in a studio. 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 rather than a battery, and carries CE, RoHS and SGS. The Bluetooth app and timer are the feature most studio owners underestimate: they let you scent your opening hours and nothing else, which means the register is at the right level when a client walks in at ten and is not quietly running at three in the morning into an empty building. Ordinary studio prudence still applies wherever you put it - keep any machine away from open equipment cases and away from the spot where lenses get changed, and do not point a mist machine at anything you care about. That is prudence and housekeeping, not a protection claim, and SOSA publishes none.
Two important product notes. The seven registers above are the water-based Hotel Collection and they run in the SOSA ultrasonics; the ₹299 bottle never goes into a Vaayu or an HVAC machine. The Vaayu and the ducted machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - run waterless nebulising oil, and the Vaayu ships with four hotel-inspired waterless blends as one of three bundle choices. If you expect to move from an ultrasonic to a Vaayu later, mention it on WhatsApp before you buy so nobody ends up with the wrong bottle.
And if you want a register with no plug, no noise and nothing to switch off - a small consultation room, a corner of reception, a loo - the SOSA reed diffusers are their own set: Morning Freshness ₹749 (Malabar lemon, mint, eucalyptus), Garden Bloom ₹799 (British rose, night-blooming jasmine), Evening Calm ₹799 (Kashmir lavender, chamomile), Mountain Breeze ₹849 (Himalayan pine, sage, cedar) and Fresh Brew ₹849 (Coorg coffee, Kerala vanilla). 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. Mountain Breeze is the one that sits closest to a studio's woody register; Fresh Brew is delightful in a home and risky in a room where somebody sits for four hours.
A reed diffuser is also the honest answer for a studio that is not sure it wants to commit yet. It has no plug, no timer, no app and nothing to switch off; it sits in a corner and does one small room at one steady level, which is exactly the behaviour you want while you are still learning what your building does. Several studios I have worked with started with two reeds and a habit of opening the windows, and only bought a machine eighteen months later when they took a bigger floor. That is a sensible order of events and nobody should feel talked out of it.
To go further: the whole dwell-time argument that sits underneath this page is set out in what a premium photography studio should smell like. If your real question is whether to commit to one register for the long term, read should a professional photography studio have a signature fragrance, which also covers bespoke composition honestly. And if you shoot video as well as stills, the variables genuinely change - longer days, bigger crews and live audio - so read what fragrance suits a high-end photo and video studio before you place a machine. And if the honest situation is that your studio does not smell bad but does not smell like much of anything, the free version of this page is how to make a photography studio smell more premium, which spends most of its length on airing, sources and cleaning rather than on machines.
What SOSA does not publish, and what this page therefore will not tell you: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order or lead time. Those depend on run hours, connected volume and setting, and they are answered properly with your floor plan in hand on WhatsApp at +91 96192 18531. Bulk orders are welcome and custom label or logo on product is available.
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.
