Placement is not a decorating decision with an airflow footnote. It is an airflow decision with a decorating constraint bolted onto the end of it. Air moves through a photography studio for reasons that have nothing whatever to do with fragrance. A supply grille pushes air out into the room. A return grille pulls air back to the plant. A split unit throws a cold jet across one wall and stirs a single room. Doors open and shut fifty times a day. And the corridor between two rooms very often behaves as a plenum that both rooms are quietly breathing through. Put a machine in the wrong metre of that system and it will do exactly what it was built to do while the room you cared about smells of nothing at all.
There is also a hard constraint that people discover on installation day rather than on planning day: the SOSA Vaayu at ₹11,999 runs on DC 12V / 1A at 5W and is mains powered, so it needs a live socket. It can stand freestanding, lay flat, mount on a wall or mount into HVAC, which gives you real freedom - but not freedom from electricity. So placement in a studio is always the intersection of three maps: where the air goes, where the sockets are, and where a client's eye lands when they walk in.
Does it need to be near a plug? Yes. The Vaayu at ₹11,999 is mains powered at DC 12V / 1A, 5W, and the ultrasonics need a socket too. It mounts freestanding, on a wall or into HVAC, so you have options - but the socket is a real constraint and it is worth walking the room with the sockets in mind before you fall in love with a position.
How far should it be from equipment? As a matter of ordinary studio housekeeping, keep any machine away from open gear cases and away from the bench where lenses get changed, and do not point a mist machine at anything you care about. The Vaayu is waterless cold-air nebulising with no water, no humidity and no wet residue, while the ultrasonics are water-based cool-mist machines that put moisture into the air. That is prudence and it is not a protection claim - SOSA does not publish one.
Then find the grilles before you find the furniture. Every studio with air conditioning has at least one supply, where conditioned air is pushed into the room, and usually a return, where room air is drawn back. Stand under each and hold a tissue up; it takes ten seconds and it tells you which is which. A machine sitting directly in a supply airstream has its output picked up and carried wherever that jet is going - often along a ceiling, across the room and out through the door - so the room nearest it smells of nothing and some other part of the building smells faintly of your register. A machine sitting near a return has its output pulled straight out of the room and back into the system. Neither of those is a fault in the machine. It is a fault in the metre you chose.
Next, aim for gentle movement rather than stillness or blast. A dead corner behind a heavy sofa, in an alcove, behind a rail of wardrobe or under a table with a cloth over it is a place where air genuinely stagnates, and a machine in it does a small, local, invisible job. Somewhere with mild circulation - a console table on the wall a client walks past, a shelf a metre or so back from the natural walking line, a wall mount above head height in a room where the AC is stirring the air gently - lets the room distribute your output for you. You want the room to do the work, not the machine.
Then apply the human constraints. Off the sightline: a client walking into a premium reception should not have their eye land on a device. Behind the desk, on a low shelf, on a wall above the picture line, tucked beside a plant - all fine. And keep it away from open equipment cases and from the spot where lenses get changed, which is simply how a careful studio treats any small appliance and any airborne anything. That is prudence and housekeeping, not a claim about protecting or harming gear, and SOSA publishes no such claim in either direction.
Finally, the electrics. The Vaayu is DC 12V / 1A, 5W and mains powered, so a live socket has to exist within reach of the position you choose - and if the answer is an extension lead trailing across a client walkway, that is not a position, it is an accident waiting to happen. The Vaayu's freestanding, wall and HVAC mounting options exist precisely so that you can put the machine where the air wants it rather than where the socket forced it. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you remember nothing else, remember that a corridor is not a room. It is the space between two rooms, it usually has a door at one or both ends, and it is where the free socket lives. A machine in the corridor scents the corridor and gives reception and the lounge whatever leaks through when the doors happen to be open. Owners then conclude the machine is underpowered and buy a bigger one, which scents the corridor harder.
The second thing worth remembering is that placement changes your level. Two studios with the same machine, the same register and the same setting can read completely differently because one machine is in a still corner and the other is a metre from a supply grille. So set the level after you have settled the position, not before, and give it a few days in the new spot before you touch the dial. Moving a machine two metres is free. Turning it up is the expensive habit.
And a practical note about installation order that saves a lot of re-drilling: live with the machine freestanding for two weeks in the position you think is right, then wall-mount it once you are sure. The Vaayu will stand or lay flat perfectly happily, so there is no reason to commit a bracket to a wall on day one.
The placement rules, in the order they actually decide the outcome
There are three families of constraint on where a scent machine goes in a photography studio, and they pull in different directions, which is why placement feels harder than it should. The first is the air itself - the boundaries of the volume, and the grilles and doors that move air across those boundaries. The second is the electricity, because every SOSA machine except a reed diffuser needs a live socket and the Vaayu is explicitly a mains-powered DC 12V / 1A, 5W device. The third is the human layer: sightlines, walkways, the client's experience of a premium space, and the ordinary prudence of a room that has expensive gear and rails of wardrobe in it.
What is not a constraint, despite being the thing people ask about first, is the middle of the room. There is a persistent belief that a diffuser belongs in the geometric centre of a space so it can radiate evenly in all directions. It does not work that way in a real building, because a real building has a dominant air pattern imposed on it by the HVAC, the doors and the heat sources, and that pattern is far stronger than anything a 5W machine is doing. Your job is to place the machine so that the room's existing air pattern carries the output for you, which almost always means near a wall, in the gentle part of the flow, upstream of where people are.
A photography studio makes this both easier and harder than a shop. Easier, because studios have very clear zones: a reception, a lounge, a corridor, a makeup area, a shooting floor. Harder, because studios are unusually full of things that eat and move air. Backdrops and drapes absorb fragrance out of the air and give it back slowly. Rails of wardrobe do the same. Continuous lighting produces heat, and heat produces convection, which is a genuine air current that changes when the lights go on. Double-height shooting bays create a chimney effect that pulls air upward and away from anybody standing on the floor. And the doors of a studio open and close far more often, and more unpredictably, than the doors of a showroom.
The last thing to say before the detail is that placement is one of the very few free variables in this whole subject. You cannot change your ceiling height. You cannot change your ventilation rate without spending real money, and you should never reduce it for the sake of fragrance. You cannot change how long a client sits in the album room. But you can move a machine two metres, and two metres is frequently the difference between a room that reads beautifully and a room that reads of nothing.
So the first act of placement is to draw the boundaries. Walk your floor plan on a normal working afternoon and mark every door that is shut more often than it is open. Those lines are the edges of your volumes. A reception and a lounge that are genuinely open to each other, with a wide opening and no door, are one volume and one machine's problem. A consultation room with a door that is closed during every single consultation is its own volume, and whatever the corridor smells like tells you nothing about it.
Do the arithmetic while you are there, because it changes the answer. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A 250 sq ft reception at 11 ft is 250 x 11 = 2,750 cu ft, and 2,750 / 35.3 is about 78 m3. A 400 sq ft lounge at 12 ft is 4,800 cu ft, about 136 m3. If those two are genuinely open to each other they are 7,550 cu ft together, about 214 m3, and one machine placed in the larger of the two will serve both comfortably. If a door separates them, you have a 78 m3 problem and a 136 m3 problem, and a machine in the corridor between them has a corridor problem.
Which of two connected rooms gets the machine? The larger one, and the one further from the entrance door, as a general rule. Air in a connected pair tends to drift towards the opening rather than away from it, and every time the front door opens, the room nearest it gets flushed. Putting the machine in the deeper room lets the shallower one receive rather than lose. There are exceptions - a strong return grille in the deeper room will overturn this immediately - but as a starting position it is right more often than not.
One more version of the same rule, because studios trip over it constantly. If you have decided that your shooting floor gets nothing, do not place the machine on the reception side of an opening that stands wide open onto the shooting floor all day. That opening makes them one volume whether you meant it to or not, and you are now dosing 500 m3 with a machine you sized for 200. Either the door gets used, or the two rooms are one room and you set the level for the pair.
The practical test is very simple and I use it in every space I walk. Stand where you plan to put the machine and ask: if I shut every door that normally gets shut, am I in the room I care about? If the answer is no, you have found a socket rather than a position.
Now the two failure modes. A machine placed in the direct airstream of a supply grille has its output captured by that jet almost immediately. This does not destroy the fragrance - it relocates it. The jet carries it along the ceiling, across the room and frequently out through the top of a doorway into wherever the air is going next. The symptom is a reception that smells of nothing while the corridor or the stairwell smells faintly of your register, and the owner's diagnosis is invariably that the machine is too small. It is not too small. It is in the wrong metre.
A machine placed near a return grille has a simpler and more brutal problem: its output is pulled out of the room. If the return is in a ceiling directly above the console you chose, you are feeding the plant rather than the room. In a ducted building, that output may then be redistributed to every other room on the same air handler, which is a strange and expensive way to scent a building you did not intend to scent. If the return is in the door undercut - which is very common in Indian fit-outs - then the machine by the door is quietly exporting to the corridor.
What you want instead is the gentle middle of the flow. Think of the room as having a fast part and a slow part. The fast part is the first two or three metres of the supply jet and the last half metre before the return. The slow part is everything else, and inside the slow part there is usually a broad, lazy circulation that carries air around the occupied zone. That is where the machine belongs: in the slow, moving part, upstream of where people actually sit or stand.
Height matters here too. Fragrance is carried by air, not dropped by gravity, but placement height changes which stream picks it up. A machine at floor level in a room with a ceiling supply and a low return sits in the return path; a wall-mounted machine at head height or a little above sits in the occupied zone where you want it. The Vaayu mounts freestanding, on a wall or into HVAC precisely so you can choose. If your studio has a ducted system and you are genuinely trying to scent a large connected floor, HVAC mounting is a legitimate answer, and so are 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.
One thing that is never the answer, in any phrasing: do not close a vent, block a return, shut off extraction or reduce air exchange to make the fragrance hang around longer. A well-ventilated studio is genuinely harder to scent, and that is a trade you accept rather than defeat. You solve it with placement, with a machine sized to the connected volume and with a sensible setting. The air in a room where people work all day is not a variable you get to spend.
First, power. The Vaayu is mains powered at DC 12V / 1A, 5W and needs a live socket; so do the ultrasonics - Boond at ₹899, Sukoon at ₹1,899 and Megh at ₹3,499. That sounds trivial until you are standing in a reception whose only socket is behind the desk on the wrong side of the room. The honest options are to accept a slightly worse airflow position that has power, to get an electrician to add a socket where you want the machine, or to use something with no plug at all. A SOSA reed diffuser from ₹749 needs no socket, makes no noise and has nothing to switch off, which is why it is the right answer for a corner that has no power and does not need much. What you should not do is run an extension lead across a walkway a bride walks down in a lehenga.
Second, the sightline. A premium studio reception is a designed object and a client's eye moves through it in a predictable order: the desk, the person behind it, the wall of prints, the seating. A device sitting in the middle of that sequence is a small, cheap-looking interruption, and the whole point of the exercise is that the client notices the room feels considered without being able to say why. Behind the desk, on a low shelf, above the picture line on a wall mount, beside a plant, tucked into a bookcase - all of these are invisible and all of them can still be in the moving part of the air. Wall mounting is genuinely useful here, and it is also the position most likely to keep a machine out of reach of a curious four-year-old on a family shoot.
Third, the gear, and let me be precise about what I am and am not saying. Ordinary studio prudence is to keep any small appliance away from open equipment cases and away from the bench where lenses get changed, and not to point a mist machine at anything you care about. That is housekeeping, and it is the same instinct that stops you putting a cup of chai on the light stand. SOSA publishes no claim that any product protects photographic equipment, damages it, or is certified safe for it, and this page will not make one in either direction. What SOSA does publish is the mechanical difference between the two systems, and it is worth knowing when you choose a spot: the Vaayu is waterless cold-air nebulising of undiluted oil, with no water, no humidity and no wet residue, while the ultrasonics are water-based cool-mist machines that put moisture into the air. Those are simply different behaviours, and a room full of open cases is a room where the sensible instinct is to keep any machine at a distance.
There is a fourth constraint that only shows up in studios: the shoot itself. A machine on a console in reception is fine until reception becomes an overflow set on a busy Saturday and a stylist puts a rail in front of it. If a spot is going to get used for something else on a big day, it is not a spot. Look for a position that survives the busiest version of your week - up a wall, behind the desk, in a niche - rather than the tidy Tuesday version.
And keep it accessible. You will refill it, you will occasionally wipe it, and somebody who is not you will have to do both. A beautiful position four metres up a wall over a staircase is a position nobody maintains, and an unmaintained machine is a machine that runs dry in month three and quietly ends your studio's consistency.
- Name the volume, shut the doors that normally shut, and stand inside it.
- Find the supply and return grilles with a tissue before you look at furniture.
- Pick a gently moving spot with a live socket, off the client's sightline.
- Keep it clear of open gear cases and the bench where lenses get changed.
Register, level, and the way placement quietly changes both
Placement and register interact more than most people expect, so it is worth being concrete about what changes when you move a machine.
The first interaction is apparent strength. A machine in gentle circulation, upstream of the seating, distributes its output through the whole occupied zone and reads as an even, low presence everywhere. The same machine in a still corner produces a strong local pocket and very little elsewhere, so a client who happens to sit near it gets far more than a client on the other sofa. That unevenness is one of the ways a room starts to feel like it has a product in it rather than an atmosphere, because the moment the level changes as you walk across a room, a person notices the fragrance as a thing.
The second interaction is which part of the register you meet. Fragrance in a room is never a flat single note; the lighter, brighter parts of a composition move and disperse differently from the heavier woods and ambers. Sitting a metre from a machine you meet more of everything at once. Sitting eight metres away in a gently moving room you meet a softer, rounder version of the same blend. That is another argument for distance and circulation rather than proximity: the register you chose was designed to be met as a room, not as a device.
Now the registers themselves, all seven of them from 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 and polished lobby calm, and it is the default for a studio reception. It is also the most forgiving register when your placement is imperfect, because it is quiet enough that a slightly hot local pocket still reads as pleasant rather than as a lot. If you know your position is a compromise - the only socket, the only wall - this is the register to compromise with.
White Tea Serenity is white tea, aloe and cedar, clean and weightless and spa-like, and it is the pale, daylight-heavy studio's answer. It is the most transparent of the seven, which makes it the easiest to place badly and still get away with, and the hardest to notice if you have parked it in a dead corner where nothing moves.
Forest Suite is cedarwood, vetiver and green leaves, grounding and biophilic green, and it belongs in concrete, steel, plants and dark timber. Woody registers are the ones I would most want to place well, because in a still corner they can pool and read as heavy, while in gentle circulation they read as structural and calm.
Tea Garden is jasmine, green tea and white tea, a serene tea-and-jasmine calm, and it is the bridal consultation answer. Place it further from the sofa than feels natural. A long-dwell room wants the lowest level in the building, and distance from the machine is one of the cheapest ways to get it.
Warm Welcome is citrus, floral and sandalwood, warm and gracious, and it is a threshold register - which makes it a reception placement question specifically. Put it deeper into reception rather than at the door, because a register that greets people is best met a step or two after the threshold rather than at it.
Old-World Glamour is amber, violet and woods, plush and evening-elegant, and it belongs in a dark portrait room rather than in a four-hour album room. It is the register that most punishes a still corner, because plush plus pooling is heavy very quickly.
Lobby Bar is citrus, pepper and amber, bold and playful and after-dark. In this vertical it has one home, an events or launch space, and in a room like that placement is dominated by where the crowd stands rather than by where the sofa is.
Those seven are the water-based Hotel Collection and they run in the SOSA ultrasonics. The Vaayu and the ducted machines run four hotel-inspired waterless blends supplied with the machine as one of three bundle choices, and the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. What I will not do is rank the seven against each other on throw or longevity, because SOSA does not publish that comparison and it would not survive contact with your particular room anyway. Connected volume, ceiling height, ventilation rate, soft material and setting swamp any difference between one blend and another, and placement sits right in the middle of that list.
And the rooms where the correct placement is nowhere: the active shooting sets, the makeup and styling area, which already has hairspray and setting spray winning in it, 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 maternity rooms unscented as well. That is not a health, safety or calming claim in either direction, and SOSA publishes none - it is simply the courteous structure, and the client's own preference overrides everything written here.
| Scent | Why it suits the mood |
|---|---|
| Inside reception, wall or shelf · the right answer | In the volume you want scented, a metre or two back from the walking line, at or above head height, off the sightline, on a live socket. Gentle circulation carries the output through the occupied zone and the level reads the same wherever a client sits. This is the position to aim for and to build a socket for if one does not exist. |
| In the corridor · the commonest mistake | A corridor is a third volume between two rooms, not a shortcut into either. The machine scents the corridor properly and gives reception and the lounge whatever leaks through when a door happens to be open. The owner concludes the machine is too small, buys a bigger one, and scents the corridor harder. Move it into a room before you spend anything. |
| Under a supply grille · output relocated | The jet from a supply grille picks the output up and carries it along the ceiling and often straight out of the room. The fragrance is not lost, it is delivered somewhere else, which is why the stairwell smells faintly of your register while reception smells of nothing. Step two or three metres out of the airstream and the same machine at the same setting behaves completely differently. |
| Beside a return grille · output exported | The most efficient way to scent your air handler. A return pulls room air back to the plant, so a machine near one is feeding the system rather than the room - and in a ducted building it may then be redistributed to rooms you never intended to scent. Find the return with a tissue and put the machine as far from it as the room allows. |
So the buying question, once you know where the machine is going. For a single 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 lounge that runs all day is where the SOSA Megh at ₹3,499 earns its 6 litre tank, mostly because a big tank means fewer trips to a machine that you have deliberately placed somewhere discreet.
For a whole connected client route, the SOSA Vaayu at ₹11,999 is the commercial answer, and its mounting options are the reason it is also the best-behaved machine to place. Waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue. Approximately 1000 m3 of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. A 400ml tank, freestanding or lays flat, wall mount or HVAC mount, DC 12V / 1A at 5W and mains powered so it needs a live socket, and CE, RoHS and SGS. The Bluetooth app and timer matter for placement too: a machine tucked discreetly behind a desk is a machine you are not going to walk over to twice a day, and the app means you do not have to.
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. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. And where there is no socket and no need for one, the SOSA reed diffusers solve the position outright: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849 and Fresh Brew ₹849, lasting about 6 to 10 weeks, with 130ml from ₹1,249 and refills at ₹2,399 for 300ml and ₹3,499 for 500ml. A reed in a still corner behaves better than a machine in a still corner, because a reed is a small local job by design.
If your real question is which room the machine belongs in rather than which metre, read should the scent machine go in reception or the main shooting area, which answers it decisively. If your studio has air conditioning doing something you do not understand, how air conditioning affects fragrance in a photography studio explains the mechanisms. And if you have already placed a machine and the shooting floor smells of nothing, the diagnostic page is why you can smell fragrance in reception but not in the main studio.
What SOSA does not publish, and what this page will therefore not tell you: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order or installation lead time. Those depend on run hours, connected volume and setting, all of which are yours rather than ours. Send a floor plan with the doors and the grilles marked on it to SOSA on WhatsApp at +91 96192 18531 and you will get an opinion about position rather than a catalogue. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition is a real SOSA service discussed there rather than priced on a page.
The SOSA scenting range
SOSA sells two different systems and one of the commonest mistakes is mixing them up. Size by the connected air volume of the room you are actually scenting - floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres. A door that stays shut ends one volume and begins another.
| Machine | System | What it is for | Price |
|---|---|---|---|
| SOSA Boond | Ultrasonic · water-based | A small desk or corner unit for one enclosed room - runs the water-based Hotel Collection | ₹899 |
| SOSA Sukoon | Ultrasonic · water-based | A larger ultrasonic for a reception or consultation room - Hotel Collection from ₹299 | ₹1,899 |
| SOSA Megh | Ultrasonic · 6L tank | A large-tank ultrasonic for a bigger lounge that runs all day | ₹3,499 |
| SOSA Vaayu | Waterless cold-air nebulising | The commercial machine - approx 1000 m3 of connected air, Bluetooth app and timer, no water and no humidity | ₹11,999 |
| SOSA Aangan | HVAC nebulising | Ducted scenting for approximately 8,000 to 10,000 sq ft | ₹25,999 |
| SOSA Meenar | HVAC nebulising | Ducted scenting for approximately 12,000 to 18,000 sq ft | ₹38,500 |
Two systems, and they are not interchangeable. The ultrasonics - Boond, Sukoon and Megh - run the water-based Hotel Collection from ₹299. Vaayu and the HVAC machines run waterless nebulising oil; the ₹299 water-based bottle never goes into a Vaayu. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is independent and not affiliated with any hotel brand. A portion of every order supports girl-child education through Nanhi Kali.
- Vaayu ₹11,999 - waterless cold-air nebulising, approx 1000 m3 connected air, Bluetooth app and timer, 400ml tank, freestanding or wall / HVAC mount, DC 12V / 1A, 5W, mains powered, CE / RoHS / SGS.
- Aangan ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar ₹38,500 for approximately 12,000 to 18,000 sq ft - both ducted into HVAC.

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.
