A portfolio or test day has a shape that argues consistently downward. Six to ten looks. A long day, often eight or nine hours. A changing area in constant use, with hair and makeup resets between looks. And a client who is frequently young, frequently new, and who did not choose the room they are standing in - the agency booked it, or the photographer did, or a parent drove them there.
That last point deserves to be said plainly, because it is the one that decides the level. In a portfolio studio, the person most exposed to a fragrance decision is often the person least able to say anything about it. A nineteen-year-old on their second test shoot is not going to tell the photographer that the room is a bit much. Neither is the agency's new-faces booker. Under-dose, and the question never arises.
There is a second person nobody counts, and they have the longest continuous exposure in the building: the parent, chaperone or agent sitting in the corner from ten in the morning until six. The model moves between the set, the changing area and hair and makeup all day. The chaperone does not move at all. Set the level for them and everything else looks after itself.
And as with every page in this section: "model portfolio" is a description of the work, not a scenting variable. Genre is an aesthetic association exactly the way interior colour is. What actually changes the answer is connected air volume, dwell time, ceiling height and ventilation.
Should the changing area be scented? No, and this is not a close call. It is in constant use across a portfolio day, the model's own clothes and bag sit in it for eight hours, and fabric takes on whatever is in the air around it and releases it slowly. Give it ventilation, a proper rail and a hook, and no fragrance. A shut door or screen ends one body of air and begins another, which makes an unscented changing area easy.
Who should I set the level for? The most sensitive person in the room, and the one with the longest continuous exposure - which on a portfolio day is usually the parent, chaperone or agent sitting in the corner for eight hours while everybody else moves around. Your own crew are next. The model is in and out of three different rooms all day and is, ironically, not the person the level should be built around.
Start by mapping a portfolio day honestly, because it does not look like any other day in this section. Call time at nine. Hair and makeup for an hour and a half. Look one at half past ten, shot for forty minutes. Back to the changing area, a hair change, a makeup adjustment, look two at half past eleven. Lunch. Looks three, four and five through the afternoon, a location change to the window light at the far end of the studio, looks six and seven, and a wrap at six with an hour of packing and a hard drive being copied. Somewhere in that day the model has been in the changing area eight separate times and in the hair and makeup chair for the better part of two hours.
Now look at who is actually exposed to your air and for how long, because it is not who you would guess. The model moves constantly between three rooms, so no single room accumulates against them. The crew move too, though less. The person with the longest continuous exposure in your building is almost always the one sitting still in the corner: the parent who drove a seventeen-year-old in from two hours away, the agency booker on a laptop, the chaperone who is not going anywhere until wrap. They have the exposure profile of a wedding album-selection client - six to eight hours in one air - and nobody ever designs for them because they are not the client, not the crew and not paying.
Design for them. If the corner where the chaperone sits is comfortable at six in the evening, the room is right for everybody. That single rule produces the correct answer without any further reasoning, and it lands you at the lowest level in this section, which is where a portfolio studio belongs anyway.
Then the changing area, which gets nothing. Three reasons stack up. It is in constant use, so whatever is in that air has eight opportunities to settle into what is hanging there. The model's own clothes, coat and bag sit in it for the whole day and go home in the evening carrying whatever the room had in it. And on a test or portfolio day much of the clothing is borrowed - the model's own pulls, a stylist's rail, pieces belonging to a brand or an agency - which is somebody else's property that should leave in the condition it arrived. Give that room ventilation, a proper rail, a hook and a mirror, and no fragrance of any kind.
Third, the level in the room you do scent, and here is the honest structural reason it goes lower than everywhere else. The people in a portfolio studio frequently did not choose to be there. A new model was sent by an agency. A young one was brought by a parent. An assistant is on their third day. None of those people has the standing, or usually the confidence, to tell a photographer that the studio smells too strong - and that is not a claim about anybody's health or state of mind, which SOSA does not publish and this page will not invent. It is simply a fact about who speaks up in a room and who does not. Whoever is most sensitive sets the level, and in this vertical they are also the least likely to say so. Under-dose, and the question never comes up.
And the order that never changes: fragrance adds scent, it does not remove odour. A long day with a steamer, hair products, a lot of fabric and lunch in the building is a source and ventilation matter. Source, then ventilation, then cleaning, then fragrance. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The check that makes this concrete: walk over to the chair where the chaperone or the agency booker has been sitting since ten, at about five in the afternoon, and read that corner. Not the middle of the room, and not the set. That chair is the highest-exposure seat in your building and nobody has ever asked it a question. If the air there is unremarkable at five, you have got the level right.
The second habit is the free one, and on a long day it matters more than any purchase. Use the natural breaks - the wardrobe change, the hair reset, the lunch hour - to open something and move air through. A nine-hour day in a closed room accumulates whatever the day contains, and no register improves an accumulated room; it just adds to it. What you never do is the opposite: do not shut a vent or reduce extraction so the fragrance holds on longer. A well-ventilated studio is genuinely harder to scent, which is a good problem you solve with placement and level.
The third is about your own nose, which on a nine-hour day is the least reliable instrument in the building. You adapted before the first look was shot. Any judgment you make at four in the afternoon about whether the register is still there is being made by somebody who cannot smell their own studio. Take the reading from the doorway on a morning the studio has been shut, or ask whoever has just arrived - the driver, the courier, a crew member coming back from lunch - before you tell them there is a diffuser running.
Multiple looks, a long day, and the person nobody counts
Four things shape a portfolio studio's answer, and none of them is the genre. Multiple looks, which means constant movement between rooms. A long day, which means high cumulative exposure for whoever stays put. A changing area in heavy use, which is a hard stop. And a client who often did not choose the environment, which changes who the level is set for.
Start with the movement, because it is genuinely unusual. In most of the studios in this bank the client stays somewhere: a sitter in a portrait room, a couple on a lounge sofa, an employee in front of a headshot backdrop. On a portfolio day the model is a moving part. Set, changing area, hair and makeup chair, set again, a different corner of the studio for window light, back to the changing area. Nobody accumulates a single room's air, which is why the model is not the person the level should be built around.
Then the day length. Eight or nine hours is normal on a portfolio or test day and it can run longer, and the people who are still there at seven o'clock are your crew and whoever came with the model. Long days are the reason this vertical shares an instruction with fashion work: your team are the most exposed people in the building, they are in that air five or six days a week, and a sensitivity report from any of them is a recalibration signal rather than a tolerance problem.
Then the changing area, which gets its own section because it is not a judgment call. And then the agency and consent question, which is the honest heart of this page and the reason its level recommendation is the lowest in the section.
What none of this is about is whether the book you are shooting is commercial, editorial, fitness or runway. Those distinctions are real and they matter to the work. They are aesthetic associations in exactly the way the paint on your cyclorama is - genuine design facts with no physical consequence in the air. The four variables that decide the answer are connected air volume, dwell time, ceiling height and ventilation, and a portfolio studio's specific combination of those is what this page is actually about. You still deserve a register recommendation on aesthetic grounds and you will get one; this page simply refuses to dress a taste judgment up as a technical one.
That person arrives at nine and leaves at six. They do not move between rooms. They do not go to hair and makeup. They sit in the same chair, in the same corner, breathing the same air, for eight or nine continuous hours. Their exposure profile is identical to a wedding client choosing an album - the longest-dwell person in this entire bank - and the difference is that nobody ever thinks about them, because they are not the client, not the crew and not the person being photographed.
Design the room for them and you cannot get it wrong. This is a genuinely useful shortcut, because it collapses a complicated multi-room, multi-dwell day into a single test. Find the chair. Sit in it at five in the afternoon, or better, ask somebody who has just walked in from the street to stand there and tell you what they get. If that corner is unremarkable after eight hours, the level is right for the model, right for the crew and right for anybody who walks in later.
There is a placement lesson attached, and it is one studios get wrong constantly. The chaperone's corner is usually the corner nobody was designing for, which is why it is often exactly where the free socket is, and therefore exactly where the machine ends up. A diffuser at head height two metres from the one person who is going to sit there for nine hours is the single worst placement available to you, and it happens by accident all the time. Put the machine on the route people move through - near the door, in the corridor, on the way to the set - low, out of the frame, and away from the chair somebody is going to occupy all day. And, as everywhere, keep it away from open equipment cases and the spot where lenses get changed, and do not point a mist machine at anything you care about. That is ordinary studio prudence and housekeeping, not a claim that any product protects equipment; SOSA publishes no such claim.
While you are looking after that corner, look after the rest of it too, because a person sitting for nine hours notices everything and mentions nothing. Somewhere to put a bag. A chair that is not a stool. Access to water without having to ask. A socket to charge a phone. Those are worth more than any register, and they cost less.
One more note on this. If the chaperone is a parent, they are also the person who will form the studio's reputation with every other parent in that agency's new-faces list. That is not a reason to scent the room; it is a reason to make the room comfortable, which usually means less of everything rather than more.
Three separate arguments say leave it unscented, and they stack.
The first is the property argument, and it is the same one that governs a fashion studio's wardrobe room. Fabric absorbs the volatile material in the air around it and releases it slowly over hours and days - that is a source fact, and it works whether the smell is welcome or not. On a portfolio day a good deal of the clothing is not yours and not the model's: a stylist's pulls, a brand's samples, pieces borrowed from an agency's rail, occasionally something rented. All of that leaves your building and goes somewhere else, and it should leave in the condition it arrived.
The second is the personal argument, which is specific to this vertical. The model's own clothes, coat and bag sit in that room from call time to wrap. Whatever the changing area's air contains has nine hours to settle into a jacket that somebody is going to wear on a train home and then to college the next morning. Nobody should leave a studio wearing the studio.
The third is the one about who is in there. The changing area is the one room where a person is alone, half-dressed and least able to leave if something bothers them. It should be plain, well ventilated, clean and unremarkable. That is not a health or safety claim in either direction - SOSA does not publish one and this page will not invent one - it is simply how you treat a room somebody has to use in that state.
What that room actually needs is unglamorous and cheap: extraction or a window that opens, a proper rail rather than a hook on a nail, somewhere to put a bag off the floor, a full-length mirror, a chair, and a laundering schedule for anything soft in it. If the room smells stuffy, the answer is airing it between looks and getting the steamer's moisture out, not a diffuser. Fragrance adds scent and does not remove odour, so a register in there would produce a stuffy room plus a register, which is a third smell and worse than either.
Write it on the same sheet as your register and your setting, in the same handwriting: changing area - no fragrance, ever. Studios lose this rule in month seven, when somebody decides that room smells stale and buys something on the way in, and nobody notices for a fortnight because everybody who works there adapted on day one.
The hair and makeup station is the same decision for a different reason. By mid-morning it holds hairspray, setting spray, primer, a hot tool and somebody's own perfume - strong volatiles that are already winning. Fragrance added on top does not blend with them; it makes a third smell that belongs to nobody. Leave it alone, keep it ventilated, and let one room carry the studio's character instead.
The rule itself is universal: whoever in the room is most sensitive sets the level, not the average and certainly not the owner. In a group of a dozen people there will reliably be somebody who is scent-sensitive, somebody who arrived with a headache and somebody who simply dislikes fragrance. That is ordinary human variation and it has nothing to do with tolerance or fussiness.
What is specific to a portfolio studio is the second half: the people most likely to be affected are the people least likely to say anything. A new model on their second or third shoot is at the start of a career in which being easy to work with is currency. A seventeen-year-old brought by a parent is in a room full of adults who all know each other. An agency's new face is being tested as much as photographed. An assistant on their third day is not going to raise the air quality with the photographer who might book them again. None of these people will tell you the room is too much. They will simply have a slightly worse day than they needed to, and you will never know.
Be clear about what that argument is and is not. It is not a claim that fragrance harms anybody, and it is not a claim that fragrance helps anybody - SOSA publishes neither and this page makes neither. It is not a claim about anybody's health, and nothing here says a SOSA product is safe for or unsuitable for any particular person; that is not something SOSA publishes and it is not something a page should invent. It is a straightforward observation about who has the standing to speak in a working room, and the sensible design response to it, which is to run the level low enough that nobody ever has to.
There is also a practical way to hand people the standing back, and it costs nothing. Mention it. At call time, alongside where the loo is and where to put a bag, say "there is a diffuser in the corner, tell me if it bothers anyone and I will switch it off". That sentence takes three seconds, it works better than any guessing, and the number of people who will take you up on it over a year is small and worth knowing about. Do the same with the agency when you book: a line in the confirmation email saying the studio runs a very light fragrance and that you will turn it off on request is the kind of small professionalism that bookers remember.
And if anybody does say something, turn it off for the day. Not down - off. A portfolio day is nine hours long and the register was never the point of it. Consistency across weeks is what makes a signature; one switched-off afternoon costs you nothing at all.
The same logic applies to your own crew, who are the most exposed people in the building over any given month. If an assistant, a retoucher or a studio manager mentions the fragrance, treat it as a recalibration signal rather than a tolerance problem: turn it down first, discuss it second, and thank them for telling you something your own nose is incapable of reporting.
- Scent one room only, and never the changing area or the hair and makeup corner.
- Set the level for the chair the chaperone sits in, read at five in the afternoon.
- Say at call time that there is a diffuser and you will switch it off on request.
- Air the room during wardrobe and hair changes, then leave the dial alone.
Which register, and why this is the lowest level in the section
To the register, then, on aesthetic terms, because that is a fair question even though it is not the technical one. There are seven in the water-based Hotel Collection, each SOSA's own hotel-inspired interpretation - SOSA is independent and is not affiliated with, endorsed by or connected to any hotel brand.
Quiet Luxury is white tea, bergamot and cedar - hushed, polished lobby calm. The default recommendation for a portfolio studio, for the same reason it is the default in a headshot room: your building holds people from very different backgrounds who did not choose to be there, and this is the register they are least likely to have any opinion about. It reads as considered rather than as scented and it works equally for a test day, a client meeting and a hire.
White Tea Serenity is white tea, aloe and cedar - clean, weightless, spa-like. The equally good choice, and the better one if your studio is pale and daylight-led: white cyclorama, big windows, light wood, minimal props. It is the coolest and most transparent register in the collection and therefore the hardest of the seven to over-notice, which is exactly the property you want in the lowest-dosed room in this section. If you cannot choose between these two, either is right.
Forest Suite is cedarwood, vetiver and green leaves - grounding, biophilic green. The right answer if your portfolio studio is the usual converted-industrial kind: polished concrete, black steel, exposed services, a high or double-height bay, plants. It agrees with that architecture and it is the one register a mixed room of stylists, assistants, agency staff and models reads as structural rather than as somebody's floral choice.
Warm Welcome is citrus, floral and sandalwood - warm, gracious hospitality. A threshold register, and reasonable at the front door of a studio whose whole manner is looking after people, which matters in a business where a lot of your visitors are new to being photographed. Keep it low, because warmth accumulates across a nine-hour day in a way cool registers do not.
Tea Garden is jasmine, green tea and white tea - serene tea-and-jasmine calm, the best-behaved floral in the collection because the jasmine sits inside tea rather than on top of it; defensible in a softer studio, though on a long day with a dozen people a floral is the register most likely to be noticed by the one person who did not want it noticed. Old-World Glamour is amber, violet and woods - plush and evening-elegant - which is beautiful in a small dark room and demanding across a nine-hour test day; if you want it, run it lower here than you would anywhere else in your building. Lobby Bar is citrus, pepper and amber - bold, playful, after-dark - and its honest home is an evening event space rather than a working portfolio day.
I will not rank those seven against each other on measured throw or longevity. SOSA does not publish that comparison and nobody can give you one that survives contact with your particular room. How a register behaves in a 255 or 510 cubic metre studio is decided by that room's volume, its ceiling height, its ventilation rate, how much soft material is in it and what level you set - and those swamp any inherent difference between one blend and another.
Now the level, which on this page is the whole argument. Everything about a portfolio day pushes it down. A long day. A chaperone with eight hours of continuous exposure in one corner. A great deal of soft material, which means the room reaches a given perceived level on less than the arithmetic suggests. A crew who are there five days a week. And a set of people who will not tell you if it is too much. So take the lowest level you would consider anywhere in your building and start below it. A portfolio studio that is quietly, consistently under-scented is doing this exactly right, and if you are ever unsure which way to move the dial, the answer on this page is down.
And the rooms that get nothing at all, written down in the same place as the register so they survive a change of staff: the changing area, the hair and makeup station, the active shooting sets, the equipment store and the retouch desk. The changing area because everything in it goes home with somebody. Hair and makeup because strong volatiles are already winning there and a third smell helps nobody. The sets because they are work rooms where a crew spends a whole day. The store because it is housekeeping, and the retouch desk because the person in that chair has the highest exposure in the business.
One register, held. Consistency is what makes a signature rather than uniqueness, and a portfolio studio gets real value from it, because agencies rebook the same rooms and a model whose first test was shot with you may come back three times in two years. Identical air on the third visit is the cheapest professionalism available.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · the default | White tea, bergamot and cedar. Ritz-Carlton-inspired, SOSA's own interpretation. The register your visitors are least likely to have an opinion about, which is the brief when a dozen people who did not choose the room share it for nine hours. Reads as considered rather than as scented, and works equally for a test day, a client meeting and a studio hire. |
| White Tea Serenity · pale, daylight studios | White tea, aloe and cedar. Westin-inspired. For white cyclorama, big windows, light wood and minimal props. The coolest and most transparent register in the collection and therefore the hardest to over-notice, which is exactly what the lowest-dosed room in this section wants. |
| Forest Suite · industrial studios | Cedarwood, vetiver and green leaves. 1 Hotels-inspired. For polished concrete, black steel, a high or double-height bay and plants. The register a mixed room of stylists, assistants, agency staff and models reads as structural rather than as a floral somebody chose for them. |
| Nothing at all · changing and makeup | The changing area, the hair and makeup station, the sets, the store and the retouch desk. The changing area is the hard stop: it is used eight times a day, borrowed clothing hangs in it, and the model's own coat and bag go home carrying whatever was in that air. Give it ventilation, a rail, a mirror and a chair - and no fragrance, ever. |
Now the machine, sized by connected air volume rather than by the kind of work you shoot. Do the arithmetic by hand: floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres.
A 750 sq ft portfolio studio at 12 ft is 750 x 12 = 9,000 cubic feet, about 255 cubic metres. A 1,500 sq ft floor at 12 ft is 18,000 cubic feet, about 510 cubic metres. A 2,000 sq ft floor at 12 ft is 24,000 cubic feet, about 680 cubic metres. A double-height shooting bay of 1,000 sq ft at 20 ft is 20,000 cubic feet, about 566 cubic metres - a reminder that studios are rarely 10 ft, that most are 12 to 16, and that a bay can be 18 to 22. And a 120 sq ft changing room at 10 ft is 1,200 cubic feet, about 34 cubic metres, which is a number you will never need because that room gets nothing.
The SOSA Vaayu at ₹11,999 is the commercial machine once you are into several hundred cubic metres of genuinely connected air. It is waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue - which is the reason it belongs in a room that has gear, wardrobe and a steamer in it. 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. It takes a 400ml tank, mounts freestanding or 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. On a portfolio day the Bluetooth app and timer matter twice: you can run it only on shoot days and only in the hours you are working, and you can switch it off from your phone in three seconds if somebody in the room says it bothers them, which is the promise this page suggests you make out loud at call time.
Every coverage figure assumes one connected body of air, and a machine cannot push scent through a closed door. In a portfolio studio that is the mechanism you are relying on, not a limitation: a shut changing-room door is what makes an unscented changing area effortless while the main room carries a register. If your changing area is only a screen in the corner of an open studio, you do not have two volumes - you have one, and the whole room should run at the changing area's standard, which is to say very low indeed.
For a smaller studio, or for a separate reception and waiting corner, an ultrasonic is enough and much cheaper. The SOSA Boond at ₹899 covers a small enclosed room; the SOSA Sukoon at ₹1,899 suits a normal reception; and the SOSA Megh at ₹3,499 with its 6 litre tank suits a room that runs all day without anybody wanting to top it up mid-shoot. All three run the water-based Hotel Collection from ₹299, with 100ml refills at ₹999, and the pack of seven 15ml bottles at ₹1,799 is the sensible way to try registers in your own air. Judge each on day five, late in the afternoon, rather than on the first morning.
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 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. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. Wherever the machine ends up, keep it away from open equipment cases and from the spot where lenses get changed, and do not point a mist machine at anything you care about - ordinary prudence and housekeeping rather than a claim that any product protects equipment, and SOSA publishes no such claim.
If you want a register with no plug, no noise and nothing to switch off - a small waiting corner or a reception - the SOSA reed diffusers run from ₹749 to ₹849 and last about 6 to 10 weeks: 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), which sits closest to a studio's woody register, and Fresh Brew ₹849 (Coorg coffee, Kerala vanilla). The 130ml is from ₹1,249, with refills at ₹2,399 for 300ml and ₹3,499 for 500ml. A reed is also a good honest answer for a studio that is not yet sure it wants a machine, because it does one small room at one steady level and there is nothing to adjust on a bad afternoon.
To go further inside this section: the wardrobe argument is set out at greater length in the best fragrance for a fashion photography studio, which explains why garments carry your air out of the building. The underlying case that genre is an association rather than a technical variable is in what a premium portrait photography studio should smell like. And if you also run high-turnover days with many people through one room, the ventilation maths is different and it is in how a luxury headshot studio should smell.
What SOSA does not publish, and what this page will therefore not state: 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 yours rather than ours. That conversation happens with your floor plan in hand on WhatsApp at +91 96192 18531. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition - a scent made only for your studio - is a real SOSA service discussed there rather than priced on a page. The cheaper honest answer first, though: one of the seven registers held consistently for a year already is a signature, because consistency makes a signature rather than uniqueness.
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.

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.
