The reasons are physical rather than medical, and it matters that they are stated that way, because SOSA does not publish health claims and this page will not invent any. Four facts about a children's studio decide it. Children are physically lower in the room than the adult who set the level. They spend a great deal of the session on the floor, which is where the rug, the mat, the beanbag and the cushions are. They are active, and a child running about moves considerably more air through their lungs in a minute than the adult standing still with a light meter. And they did not choose to be there, will not be asked, and mostly will not report discomfort in a way anybody recognises - a five-year-old does not say "this room is too strong", they get restless, cling to a parent, or ask to go outside, and a photographer reads that as shyness and keeps shooting.
None of those is a claim about anybody's health. They are observations about where a small person's head is, what they are lying on, how much they are moving and whether they have any way of telling you. Put together, they mean the level in a children's studio should be set lower than anywhere else in the building, and in the shooting room itself the honest default is nothing at all. The waiting area can carry a quiet register at a low level, and a parent's own preference overrides every word of this page without needing to be explained.
Why is a children's room different from an adult one? For four physical reasons rather than any medical one. Children are lower in the room than whoever set the level, they spend the session on the floor with the rug and the cushions, they are moving and therefore moving more air, and they will not tell you if something bothers them. A studio cannot survey the people it is dosing, so it sets the level for the least tolerant person who could reasonably be there.
Where should the machine physically go? Out of reach, off the floor and out of the play area, with no cable crossing a floor that has children on it, and with spare bottles stored away rather than on a low shelf. That is ordinary premises prudence - the same thought you would give a hot cup of tea or a light stand - and it is not a safety claim about any product. A reed diffuser from ₹749 belongs on a high ledge for the same reason, or not at all.
The four reasons are worth stating slowly because they are so often replaced by vaguer, less honest ones. First, height. You judged the room standing up, with your nose somewhere near five and a half feet. A four-year-old's is at about three and a half, a toddler's at two, and a baby on a mat is at floor level. You have never smelled your own studio from any of those heights, and a machine on a side table or a bottle on a low shelf is putting its output close to them and further from you. Second, the floor. Children lie on it, crawl on it, roll about on it and put their faces into the rug, and the rug is the item in the room that holds and re-releases smell most persistently. Whatever the room has been given, the floor textiles have some of it.
Third, activity. A shoot with children is not a still shoot. They run between marks, jump, get carried, laugh, sometimes cry, and a person doing all that is moving far more air through themselves per minute than the adult standing behind the camera who decided the setting. That is a plain physical asymmetry between the person setting the level and the people receiving it. Fourth, and most importantly, consent and reporting. An adult client who finds a room heavy can say so, step outside, or simply not book again. A child did nothing of the sort: they were brought, they will not be asked, and if the room bothers them the signal arrives as restlessness, clinginess or wanting to leave, which every photographer in the world reads as a shy child rather than as a room. That asymmetry alone would justify running low even if the other three did not exist.
What none of that is: a claim that fragrance is harmful to children, or helpful to them, or safe for them, or unsafe. SOSA does not publish anything of that kind and this page makes no such statement in either direction. It is a design argument about who the level should be set for, and the answer is the person with the least ability to tell you.
So the practical shape is simple and cheap. The shooting room low or, better, unscented. The waiting area low, because that is where the adults sit and where a quiet register earns its place. Any machine placed where a child cannot reach it, with no cable trailing across a play floor, which is ordinary premises prudence of exactly the kind you already apply to light stands, cables and hot lamps. And the parent's own view outranks all of it: if somebody would rather there was nothing, the answer is to remove it, not to reassure them. A portion of every SOSA order supports girl-child education through Nanhi Kali.
"Strong" is also a comparative that hides who is doing the comparing. Strong compared to what? Almost always, compared to what the owner could smell at four in the afternoon in a room they had been standing in since ten, which is a hopeless baseline. Adaptation is ordinary and universal: the one human being in the building least qualified to judge the level is the one holding the dial. Ask somebody who has just come in from the street, before you tell them there is anything running.
And your team is the other check, and the one that should be listened to first. Assistants, retouchers and the person who runs the play corner are in that air for eight to ten hours a day, five or six days a week, while a family is there for ninety minutes. If a member of staff mentions the scent, that is a recalibration signal and not a tolerance problem. Turn it down, then have the conversation.
Four physical reasons, and not one of them is medical
The question "should children's studios use strong fragrance" contains a hidden assumption worth removing before answering it: that there is a category of commercial space where strong fragrance is the right answer, and the only question is whether a children's studio qualifies. There is not. No room a paying client sits in should be strong, anywhere in this bank. What makes a children's studio a separate page is not that it needs a special rule; it is that it removes every safety margin that lets a mistake go unnoticed elsewhere.
In an adult consultation room, an over-scented afternoon has a self-correcting mechanism. Somebody says something, or shifts in their seat, or mentions it on the way out, or does not come back and you eventually work out why. In a children's studio that mechanism is gone. The people most exposed to the air are the ones with no vocabulary for it, no standing to object and no reason to think the room is something you can comment on. The parent might notice, but a parent watching a photographer try to get their two-year-old to look at a lens is not thinking about the air, and would in any case usually rather not make a fuss on a day they have paid for.
The physical facts stack the same way. Take a modest children's studio: a shooting room of 250 sq ft at 12 ft is 250 x 12 = 3,000 cubic feet, and 3,000 divided by 35.3 is about 85 cubic metres. That is a small body of air with three adults, two children, hot lights and a rug in it. A larger room of 400 sq ft at 12 ft is 4,800 cubic feet, about 136 cubic metres, which is more forgiving but not by much once the door is shut and the AC is recirculating. Small volumes do not need much of anything to become a lot, and children's studios tend to be small rooms because small rooms are easier to control acoustically and easier to keep a toddler inside.
There is also an accumulation problem that is specific to this kind of studio and that owners rarely connect to the fragrance question. A children's room is used in a rhythm: an hour of activity, twenty minutes of turnaround, another hour of activity, five or six times on a Saturday. Each session leaves something behind - warm bodies, snacks, a nappy, wet shoes, a jacket over the back of a chair, whatever eleven small people brought in - and by the fourth booking the room smells of the day rather than of anything you chose. The instinct at that moment is to reach for the dial, because the dial is the thing within reach. It is precisely the wrong move, and it is how a studio ends up running at three times its original level by the end of a season. What that room needs at two in the afternoon is a door held open for five minutes, a bin taken out of the building and the blanket sent to the laundry basket. Fragrance adds scent and does not remove odour, so anything added on top of an accumulated afternoon makes a third smell rather than a fresh room.
The last thing to name is what the studio gains by getting this right, and it is not a commercial claim, because there is not one to make. Ambient scent is associated with improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. That is the ceiling, it applies to the waiting area where adults sit, and it is worth ₹299. Nothing in the research or in SOSA's copy supports scenting the room where the children are, and a studio that scents it anyway has taken all of the risk for none of the modest benefit.
They are on the floor. A children's session happens down there: lying on the rug, crawling across the mat, sitting on the beanbag, face into the cushions. Those are exactly the items that hold and slowly re-release whatever has been in the room, including fragrance, including detergent and fabric conditioner, including the last three families. This is the point at which this page and the laundry rota become the same conversation, because in a children's studio the fragrance load a child actually meets is as much a laundry decision as a diffuser decision.
They are moving. A shoot with children involves running, jumping, being carried, being tickled, occasionally crying. A person doing all of that moves substantially more air through themselves in a minute than the adult standing at the camera who chose the setting. The asymmetry is not subtle and it runs entirely one way: the person deciding is the person receiving the least.
They did not choose it and will not report it. This is the reason that would be sufficient on its own. Adults self-select and self-report. A client who finds your lounge heavy has options: say something, sit near the door, cut the meeting short, not rebook. A child has none of them. They were brought, they will not be consulted, and their expression of discomfort is behavioural rather than verbal - restless, clingy, wanting to be outside, wanting to be held, refusing the last ten minutes of a session. Every one of those looks like an ordinary shy child to a photographer, which means the feedback loop that protects an adult client does not exist here at all.
Say all four out loud and the design conclusion is unavoidable: you set the level for the person with the least ability to tell you, and in this building that is a small person on a rug. In practice that means the shooting room gets nothing, or the lowest setting in the building if the room is genuinely part of an open front-of-house that cannot be separated.
And to be exact about what these four sentences are not: they are not a statement that fragrance harms children, helps them, is safe for them or is unsafe for them. SOSA publishes no claim of any kind in either direction and this page makes none. They are statements about height, posture, activity and the ability to complain, which is a design brief rather than a medical one.
The failure sequence is always the same and studio owners describe it to me in almost identical words. Week one: the level is set, it seems right, everybody is pleased. Week three: "it seems to have faded". The dial goes up. Week six: "it faded again". Up again. By week ten the studio is running at three times where it started, and the only person in the building who thinks it is correct is the person who has moved it every time. Nothing faded. The nose judging it adapted, and then adapted to the new level, and then adapted again.
The correction is procedural rather than clever. Write the setting down the day you choose it, on paper, next to the machine. Put one named person in charge of changing it. Agree that "it seems to have faded" is not a reason to touch anything, and that the only evidence that counts is three separate people who have just walked in from outside, asked before they are told there is a diffuser running. If two of the three name a product, come down. If all three say they notice nothing at all and nobody is bothered, you are approximately right and should leave it for a month.
In a children's studio, add one more rule to that list: the level never goes up during the day. Not on a busy Saturday, not after a session that left the room smelling of the day, not because the play corner has had eleven children through it since ten o'clock. A room that smells of the day is asking for air and a laundry basket, not for a bigger dose, and a level raised at four o'clock is a level that is wrong for every family arriving at ten tomorrow morning.
Your staff deserve the deciding vote here, and it is worth saying why plainly. They are in that air eight to ten hours a day, five or six days a week, while a family gets ninety minutes. They are the most exposed people in the building by a very large margin, and they are also the people most likely to keep quiet about it because they do not want to seem difficult. If an assistant mentions the scent, the correct response is to turn it down first and discuss it second. A sensitivity report is a recalibration signal, not a tolerance problem.
There is one more honest observation about the word "strong". People almost never mean intensity when they use it; they mean noticeable as a product. A room can be pleasant and present without a single person being able to name what is in it, and the moment somebody can say "oh, that's vanilla", the level has crossed from atmosphere into product. In a children's studio, atmosphere in the waiting area and nothing in the shooting room is the entire target.
Concretely. Put a machine high - a shelf, a ledge, a wall mount - rather than on a side table at the height of a curious three-year-old. Keep the cable out of the traffic route entirely; a cable crossing a floor that children run on is a trip hazard first and a diffuser question second, and if the only socket is on the wrong wall then the honest answer is that the machine goes in the other room. Do not put it in the play corner, on the rug, or next to the box of toys. Keep spare bottles and refills in a cupboard rather than on an open low shelf, for the same reason you keep the cleaning products there. And in a room where you are working with a child, a machine that is silent is worth more than one that hums, because you are trying to hold a small person's attention against everything else in the room.
The reed diffusers deserve a specific note here, because they are the product I most often recommend in a family building and they need the most careful placement. A reed diffuser is an open glass bottle of liquid with sticks in it. It has no plug and no cable, which removes two problems, and it cannot be turned up, which removes the biggest one. But it is knockable, and the sticks are interesting to a small person, so it goes on a high ledge in the waiting area or it does not go in at all. That is not a claim about the product; it is the same judgement you would apply to a vase of flowers on a low table.
Ordinary studio prudence about equipment applies as usual and is worth repeating: 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. The ultrasonics - Boond at ₹899, Sukoon at ₹1,899 and Megh at ₹3,499 - are water-based cool-mist machines that put moisture into the air, so give them clearance from gear and from anything soft you would rather stayed dry. The Vaayu at ₹11,999 is waterless cold-air nebulising with no water, no humidity and no wet residue, which is why it is the machine that suits a room with equipment in it. None of that is a statement that any product protects or damages photographic equipment, and SOSA publishes no such claim.
The last placement thought is about which room, not which shelf. If the waiting area and the shooting room are one connected volume with no door, then a machine in the waiting area is a machine in the shooting room, and the honest options are to run it very low or to run nothing. If there is a door and it stays shut, you have two bodies of air and you can scent one and leave the other alone, which is the whole structure this section of the bank is built on.
- Default the shooting room to nothing, and write that on the plan as a decision.
- Set the waiting area for someone arriving from outside, then go one notch lower.
- Write the setting down, name one owner, and never raise it during the day.
- Put the machine high and out of reach, with no cable across the play floor.
What the waiting area can carry, and where the machine goes
So where does fragrance actually belong in a children's studio? In the waiting area, at a low level, in one register, held steady. That room holds parents, grandparents, an older sibling doing homework and whoever came along, and it is the room where a quiet character genuinely improves how the place feels. It is also the room that people arrive into from outside with a clean nose, which is exactly why it must be set for them rather than for you.
From the water-based Hotel Collection, and remembering that each is SOSA's own hotel-inspired interpretation and that SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand, the shortlist for a children's front-of-house is three. Quiet Luxury - white tea, bergamot and cedar - is hushed and polished and the most broadly unobjectionable of the seven, which is the correct target in a room whose occupants change completely every ninety minutes. White Tea Serenity - white tea, aloe and cedar - is the lightest-reading of them, clean and weightless, and if your instinct is "as little character as possible while still having some", this is that. Warm Welcome - citrus, floral and sandalwood - suits a studio whose positioning is family and hospitality, on the strict condition that the level stays genuinely low, because sandalwood run high is the exact thing this page is arguing against.
The remaining four for completeness. Forest Suite is cedarwood, vetiver and green leaves, grounding and green, and it works if the building is concrete and plants rather than pastel and soft. Tea Garden is jasmine, green tea and white tea, the floral that behaves because the jasmine sits inside tea. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush is not the brief in a room with a play corner. Lobby Bar is citrus, pepper and amber, bold and after-dark, and it has no business in a children's studio at all.
Whichever you pick, run one register for the whole front-of-house rather than a different one per room. Different levels of one register read as a building with a personality; different registers in adjoining rooms read as a building that has not decided what it is, and everyone feels the seam at the doorway without being able to say what changed. In a children's studio there is a second reason: a single register is one thing to explain to a parent who asks, and "it is the same in our waiting room and it has been for a year, and there is nothing in the shooting room" is a clean, true, unshowy sentence.
The reed diffusers are frequently the better buy here, and I say that knowing it is the cheapest thing on the list. From ₹749, they have no plug, no cable, no noise and no dial, and each of those absences is worth something specific in a building full of children: nothing to trip over, nothing humming while you are working a three-year-old, and nothing that can be turned up on a busy Saturday. Morning Freshness at ₹749 is Malabar lemon, mint and eucalyptus. Mountain Breeze at ₹849 is Himalayan pine, sage and cedar and sits closest to a woody studio register. Garden Bloom at ₹799 is British rose and night-blooming jasmine, Evening Calm at ₹799 is Kashmir lavender and chamomile, and Fresh Brew at ₹849 is Coorg coffee and Kerala vanilla. They last about 6 to 10 weeks, the 130ml is from ₹1,249, and refills run ₹2,399 for 300ml and ₹3,499 for 500ml. Put any of them on a high ledge, away from the play corner.
A word about who else is in that waiting area, because it changes the level rather than the register. In a children's studio the room holds a parent who is not needed for the first twenty minutes, a grandparent who came to watch, an older sibling with homework and a bag of crisps, and sometimes a baby asleep in a pram. They are not passing through; they are sitting there for the length of the session. That makes the waiting area behave like a lounge rather than a threshold, and a lounge takes the lowest setting in the building. Set it for a parent arriving from the street with a clean nose, then go one notch lower again, and let the fact that it is the same on every visit do the work that a higher level would otherwise be asked to do.
And the rooms that get nothing, written down as a decision rather than left as an oversight: the room where the children are photographed, the changing area, and any newborn room, which should be fragrance-free. Write the unscented rooms on the same sheet as the scented ones, otherwise a helpful new assistant will add a plug-in to the play room in month seven and nobody will remember why it was not there.
One more time, because it is the sentence that outranks the rest of the page: a parent's own preference overrides every recommendation here. If a parent would rather there was nothing at all, the answer is to take it out of the room, not to explain why it is fine. That takes ten seconds with a reed and one tap with the Vaayu app, which is a genuine argument for both.
| Scent | Why it suits the mood |
|---|---|
| The shooting room · nothing, or the lowest in the building | Where the children actually are: lower in the room, on the rug, moving, and unable to tell you anything. The default is no fragrance at all, written on the plan as a decision. If the room is genuinely open to the front-of-house with no door, then the whole connected volume runs at the shooting room's level, which means very low indeed rather than a compromise in the middle. |
| The waiting area · one register, low | Where the adults sit, and the only room in the building where a quiet character earns its place. One register from the water-based Hotel Collection from ₹299 on a small ultrasonic, or a reed diffuser from ₹749 on a high ledge. Set it for a parent arriving from outside with a clean nose, then go one notch lower and leave the dial alone for a month. |
| The play corner and the floor · a laundry job | Rug, mat, beanbag, cushions and toys, which is where a child's face actually is and which holds and re-releases whatever has been in the room. This is a rota, not a fragrance decision, and it includes choosing the least perfumed detergent and conditioner you are willing to buy, since those sit directly against a child all session. |
| Machine placement · premises prudence | High, out of reach, out of the play area, with no cable crossing the floor and spare bottles in a cupboard rather than on a low shelf. Silent is better than humming in a room where you are holding a small person's attention. Keep any machine away from open equipment cases and the spot where lenses get changed - prudence and housekeeping, not a claim that any product protects or harms equipment. |
The buying answer for a children's studio is deliberately modest, because the only room being scented is the waiting area. If your front-of-house is one enclosed room, a SOSA Boond at ₹899 with the water-based Hotel Collection from ₹299 is enough. For a normal reception-plus-waiting area, a SOSA Sukoon at ₹1,899, with 100ml refills at ₹999 and a pack of seven 15ml bottles at ₹1,799 if you want to try registers in your own air. A SOSA Megh at ₹3,499 and its 6 litre tank only makes sense if the front-of-house is large and runs all day. And for a lot of studios the honest recommendation is a ₹749 reed diffuser on a high shelf and nothing else in the building.
The SOSA Vaayu at ₹11,999 comes into it only when the connected front-of-house is genuinely large: waterless cold-air nebulising of undiluted oil, no water, no humidity and 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. Do the arithmetic before assuming you need it. A 250 sq ft waiting area at 12 ft is 3,000 cu ft, about 85 m3; a 400 sq ft one at 12 ft is 4,800 cu ft, about 136 m3. Both of those are ultrasonic territory several times over. Where the Vaayu earns its price in a children's building is the Bluetooth app and timer - scenting only opening hours, and switching the whole thing off from across the room in one tap when a parent asks - plus a 400ml tank, freestanding or wall and HVAC mounting, DC 12V / 1A at 5W so it needs a live socket, and CE, RoHS and SGS.
Two systems, and they are not interchangeable. The ultrasonics are water-based cool-mist machines. 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 ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. If you are buying an ultrasonic now and expect to take a bigger floor later, say so on WhatsApp before you buy so nobody ends up with the wrong bottle.
To go further inside this section: the free half of this argument - airing on a schedule, the fresh-air setting and the laundry rota that decides what a child actually meets on the floor - is set out in how to keep a family photo studio feeling fresh without heavy fragrance. The mechanism that lets a scented waiting area sit beside an unscented shooting room, and the four gaps that defeat it, is how to create fragrance-free zones inside a photography studio. And if your building runs a newborn at ten and a bridal consultation at two in the same rooms, the strategy page is how to design a scenting strategy for a studio serving different types of clients.
What SOSA does not publish, and what this page therefore will not state: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or lead time. Those depend on run hours, connected volume and setting. Talk them through with your own floor plan 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. For a children's studio, though, the cheapest honest answer usually wins: one quiet register in the waiting area, held low for a year, and nothing at all in the room with the rug in it.
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.
