The procedure in one sentence: draw the plan, mark every door that stays shut, measure each resulting volume, strike out every volume that should not be scented at all, and only then look at machines. Everything else on this page is those five instructions broken into nine steps you can actually run this afternoon, with a real studio worked all the way through so you can compare the arithmetic against your own building.
Two things about the method are worth flagging before you start. The first is that it is an air calculation and not a floor-area calculation. Floor area is one of two inputs; ceiling height is the other, and studios are commonly 12 to 16 ft with double-height shooting bays at 18 to 22, so the assumption of 10 ft that most online calculators quietly make will undersize you badly. The second is that the most valuable step is not the arithmetic at all. It is the striking-out. In the worked example below, the building holds about 975 cubic metres of air and the calculation ends with a requirement of about 204 - roughly a fifth - because four fifths of the building is rooms where people work rather than wait.
And there is a final step that people skip because it feels unscientific, which is the one that most often saves the whole exercise: verify by walking in from outside with a fresh nose. The person standing inside the studio adapted to it within minutes of arriving and is the least reliable instrument in the building. No amount of correct arithmetic survives a level set by an adapted nose.
What ceiling height should I assume? Measure it, and never assume 10 ft. Photography studios are commonly 12 to 16 ft, and a double-height shooting bay can be 18 to 22. The same 1,000 sq ft footprint is 12,000 cu ft and about 340 m3 at 12 ft but 20,000 cu ft and about 566 m3 at 20 ft. That is a two-thirds difference in the air you are sizing for, on an identical plan.
How do I check that I got it right? Leave the building for at least twenty minutes and walk back in as if you were a client, or come in on a morning the studio has been shut. Judge the first four seconds from the doorway. Better still, ask three people arriving off the street before you tell them there is a diffuser running. Your own nose adapted hours ago and will always tell you it needs turning up.
1. Get a plan. An A4 sketch is fine if it is topologically honest about what opens into what. 2. Mark every internal door and label it shut or open - shut meaning shut at three o'clock on a working Saturday, not shut overnight. 3. Outline the connected volumes. Every group of spaces you can walk between without touching a handle is one volume. Number them. 4. Measure each one: floor area times ceiling height gives cubic feet, cubic feet divided by 35.3 gives cubic metres. Measure the height rather than assuming it. 5. Write dwell time in minutes on each volume - how long a human being actually stays in that air. 6. Strike out every volume that should not be scented at all. 7. Now, and only now, match a machine to each survivor by cubic metres. 8. Choose one register for the whole surviving set, set the level low and write it down. 9. Verify from outside, with a nose that has been out of the building.
Run that on a real studio. Take a 2,200 sq ft building with a double-height bay: reception 180 sq ft, client lounge 300, corridor 120, consultation room 220, makeup and styling 160, changing room 100, kit store 120, and a shooting bay of 1,000 sq ft. The front of house is 12 ft; the bay is 20 ft.
Step four, by hand. Reception 180 x 12 = 2,160 cu ft, and 2,160 / 35.3 is about 61 m3. Lounge 300 x 12 = 3,600 cu ft, about 102 m3. Corridor 120 x 12 = 1,440 cu ft, about 41 m3. Consultation 220 x 12 = 2,640 cu ft, about 75 m3. Makeup 160 x 12 = 1,920 cu ft, about 54 m3. Changing 100 x 12 = 1,200 cu ft, about 34 m3. Kit store 120 x 12 = 1,440 cu ft, about 41 m3. Bay 1,000 x 20 = 20,000 cu ft, about 566 m3. The whole building is 34,400 cu ft, which divided by 35.3 is about 975 m3.
Look at that bay for a second, because it is the reason the method exists. It is 45 per cent of the floor and 58 per cent of the air. If you had sized on square footage you would have got the building badly wrong in one direction; if you had assumed a flat 12 ft ceiling you would have got it wrong in the other, since at 12 ft the same footprint would be 12,000 cu ft and the building would total 26,400 cu ft, about 748 m3.
Step six, the striking-out. The bay is a working area and gets nothing. Makeup and styling has hairspray, setting spray and primer already winning in it, and fragrance adds scent rather than removing odour, so it gets nothing. The changing room is a laundry and ventilation job. The kit store is a cupboard. That removes 20,000 + 1,920 + 1,200 + 1,440 = 24,560 cu ft, about 696 m3, from the calculation in one pass.
What survives is reception, lounge and corridor as one connected volume of 2,160 + 3,600 + 1,440 = 7,200 cu ft, about 204 m3, plus the consultation room behind its door at about 75 m3. A building holding 975 m3 of air has a fragrance requirement of about 204 m3 on the route and 75 m3 in one room. One Vaayu at ₹11,999 would cover the route five times over; a Megh at ₹3,499 or a Sukoon at ₹1,899 would also serve it, and the consultation room is a ₹1,899 or a ₹749 reed. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If your calculation comes out at something close to the whole building, you have not done step six honestly. Go back and ask, room by room, who is in this room and for how long. A room full of crew for ten hours is not a fragrance opportunity. A room where one retoucher sits for nine hours in the dark is not a fragrance opportunity. A cupboard is not a fragrance opportunity. Only the rooms where clients wait are, and there are usually three of them.
The other thing that goes wrong is doing the arithmetic beautifully and then setting the level by feel while standing in the middle of the result. The arithmetic tells you what machine to buy. It does not tell you where to set it, and no calculation can, because the correct level is a judgement about how a room feels to somebody who has just arrived. That is what step nine is for, and it is the step that separates a studio that smells considered from one that smells purchased.
Keep the working. A sheet of paper with each volume, its cubic feet, its cubic metres, its dwell time and either a machine or the word "nothing" is a document you will use again. Studios move walls, hang doors, take the next floor and convert a store into a second consultation room, and every one of those changes the calculation. A building that has been re-measured after a partition went up is a building that never has to wonder why the scent "faded" in March.
The nine steps, run on a real studio from the plan to the fresh-nose check
The reason this needs a procedure at all is that the intuitive method - look at the square footage, look at a coverage figure, divide - is wrong in three separate ways at once, and the three errors do not cancel.
The first error is treating floor area as the input. Air is three-dimensional and a studio's third dimension is unusually large: 12 to 16 ft is normal, a double-height bay is 18 to 22, and the difference between assuming 10 and measuring 16 is a sixty per cent underestimate of the air. The second error is treating the building as one thing. A coverage rating assumes one connected body of air, and a studio is a set of separate bodies with doors between them; adding up the whole building and dividing by a rating produces a number that describes no real situation. The third error, and the expensive one, is assuming that all the air in the building is air you want scented. In a photography studio the majority of it is not.
Run those three errors together on a 2,200 sq ft studio and you get: a floor-area calculation at an assumed 10 ft giving 22,000 cu ft and about 623 m3, treated as one volume, and answered with one machine that is then expected to fill rooms it cannot reach. The correct calculation on the same building gives 975 m3 of total air, of which about 204 m3 on one connected route and about 75 m3 in one closed room are the actual requirement. The intuitive method got the total wrong, the structure wrong and the target wrong, and it still produced a plausible-looking number, which is what makes it dangerous.
What follows is the long version of the procedure, with the three places people get stuck dealt with properly: what "stays shut" really means, how to handle a room whose door is sometimes open, and how to verify the result when the only measuring instrument available is a human nose that stops working after four minutes in the room it is measuring.
Step two: mark every internal door, shut or open. This is the step people do carelessly, and there is a specific definition that makes it useful. "Shut" means shut during the hours you care about, which is when clients are in the building. Not shut at night. Not shut when the studio is empty. A consultation room door that is open all week and closed for three hours every time an album session happens is a shut door, because those three hours are precisely the hours the room's air matters. Conversely a store door that is technically fitted but is always propped open with a light stand is an open door, and you should record what actually happens rather than what the architect intended.
Mark two other things while you have the pen out. Mark any acoustic or sealed door with a double line, because those are absolute boundaries with the leaks engineered out and nothing crosses them. And mark any air-conditioning return grille, because a return grille pulling air out of a room can separate two spaces that the plan says are joined; in practice a room being emptied of air faster than your register arrives behaves like a room with a door on it. If you have ever had a reception that smells right next to a room that smells of nothing, with no door between them, that grille is very often the answer.
Step three: outline the connected volumes. Draw a loop around every group of spaces you can walk between without touching a handle. Number the loops. In a normal multi-room studio you will end up with somewhere between four and eight, and that count is not your machine count - it is your candidate list.
Step four: measure. Floor area multiplied by ceiling height gives cubic feet. Cubic feet divided by 35.3 gives cubic metres. Do it per space and add within a connected loop, rather than trying to do it in one go. And measure the ceiling with an actual tape or a laser rather than estimating, because this is where the biggest single error in the whole method lives. A studio at 12 ft, 14 ft and 16 ft is three different buildings: the same 2,000 sq ft floor is 24,000 cu ft and about 680 m3 at 12, 28,000 cu ft and about 793 m3 at 14, and 32,000 cu ft and about 907 m3 at 16. A 3,000 sq ft floor is 36,000 cu ft and about 1,020 m3 at 12, 42,000 and about 1,190 at 14, and 48,000 and about 1,360 at 16. A double-height bay changes it more dramatically still: 1,000 sq ft at 20 ft is 20,000 cu ft and about 566 m3, and 1,500 sq ft at 20 ft is 30,000 cu ft and about 850 m3. Never assume 10 ft in a studio. It is the single most common wrong number in this whole category.
Two measurement details that come up constantly. A mezzanine is connected to whatever is underneath it whether the plan admits it or not, so add it into that loop rather than treating it as a separate room, and expect warm air and whatever it is carrying to collect up there. And a sloping or pitched roof should be measured at its average height rather than its peak, which is a rough approximation and entirely good enough for this purpose - you are sizing a machine, not filing a structural calculation.
Those numbers do two things. They tell you which volumes take the lowest level - the longest number always takes the lowest dose, because a scent you love for ten minutes is tiring at hour three - and they tell you which volumes are working rooms rather than waiting rooms, which is what step six turns on.
Step six: strike out every volume that should not be scented at all. This is the most valuable step in the method and it is the one no coverage calculator will ever perform for you. The standing list for a photography studio:
The active shooting sets, because the crew is in them for eight to ten hours and the client is being lit and directed rather than experiencing the room. The best opportunity in this vertical is reception, consultation, bridal and client lounges and waiting areas, not the sets. The makeup and styling area, because hairspray, setting spray, primer and a hot tool are already there and fragrance adds scent rather than removing odour, so anything you add makes a third smell that walks out on the talent. The changing room, which is a five-minute room where a client is standing in their own clothes, and which is a laundry and ventilation job. The kit store, which is a cupboard that needs airing. The edit or grade suite, which is the strictest dwell-time case in the building; if the person who sits in it wants a ₹749 reed on their own desk, that is their decision rather than the studio's. 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; it is not a basis for any health, safety or calming claim in either direction, and the client's own preference overrides everything on this page.
In the worked studio, striking those removes 20,000 cu ft of shooting bay, 1,920 of makeup, 1,200 of changing room and 1,440 of store: 24,560 cu ft, about 696 m3, out of a building holding about 975. The requirement falls to about 204 m3 on the connected front of house and about 75 m3 in the consultation room. That is the collapse, and it is why the answer to almost every sizing question in this bank is smaller than the reader expected.
One discipline that costs nothing and saves a lot of confusion later: write the struck-out volumes on the plan as deliberate blanks, in the same handwriting as the ones that get machines. A blank that looks like a decision survives staff changes. A blank that looks like an oversight gets helpfully filled in by somebody six months from now, and then you have a fragrance in the makeup room and no memory of why you did not want one.
There is also a step-six question worth asking about the rooms that survive: is this room better served by nothing than by something? A very small consultation room with a good window, aired between sessions, sometimes is. The order of operations never changes - source, then ventilation, then cleaning, then fragrance - and if a room's problem is that it was shut all weekend, the answer is a window and twenty minutes, not a machine. A well-ventilated studio is genuinely harder to scent, which is a good problem, and you never solve it by reducing air exchange, closing vents or shutting off extraction so the fragrance hangs about longer.
Two matching rules. Headroom is good, not waste: a machine running low in a volume it can hold easily gives a steadier result than one working at the top of its band, and steady is the target. And a machine has to physically live inside its volume, near a socket, in the air path rather than in the dead corner where the spare plug happens to be. Keep it away from open equipment cases and from where lenses get changed, and do not point a mist machine at anything you care about - housekeeping and prudence rather than a protection claim, since SOSA publishes none.
Step eight: one register, low level, written down. Choose one register for every surviving volume rather than one per room, because different registers in adjoining rooms produce a seam a client feels at every doorway. Then set the level lower than feels right, differentiating only by dwell time: a little presence in a thirty-second reception, a genuine whisper in a three-to-six-hour consultation room. Write the setting on a card next to the machine and give one named person the dial. A written setting is a decision; an unwritten one is a memory, and memories drift upward.
Step nine: verify with a fresh nose, from outside. This is the step that makes the other eight worth doing, and it is not optional, because the human being running the calculation is standing inside the answer and adapted to it within about four minutes of arriving. That adaptation is completely ordinary and it is the single largest cause of over-scented commercial space in India.
Three ways to do it honestly, in ascending order of usefulness. Leave the building for at least twenty minutes and come back in as if you were a client - through the front door, not the back one - and judge the first four seconds from the threshold rather than the middle of the room. Better: come in on a morning the studio has been shut, which gives you the coldest and most honest reading available, and it is also the exact reading a Tuesday-morning client gets. Best: ask three people who have just come in off the street what they notice, before you tell them there is a diffuser running. If nobody mentions it and nobody is bothered, you are approximately right. If two of the three name a product, come down a notch.
And build the asymmetry into your rules from day one: the level goes down easily and up only under evidence. If three separate visitors on three separate days all say they cannot smell anything, move it up one notch, once, and leave it a fortnight. "I cannot smell it any more" from somebody who has been in the building since nine is not evidence; it is the expected behaviour of a working nose. Your staff are the other instrument, and the more reliable one for the opposite reason: they are in that air eight to ten hours a day, five or six days a week, while a client gets three hours twice a year. If an assistant, a retoucher or a makeup artist mentions the scent, treat it as a recalibration signal and not a tolerance problem. Turn it down first, discuss it second.
Then re-run the whole calculation whenever the building changes. A new partition, a door hung where there was an opening, a store converted into a second consultation room, a mezzanine put in, the floor above taken on: each of those changes the volumes and therefore the answer. It is a plan calculation, not a fragrance calculation, and it goes out of date the day somebody picks up a drill.
- Draw the plan and mark every internal door shut or open, as it is with clients in.
- Outline the connected volumes, then measure each: area x height / 35.3 for m3.
- Write dwell time in minutes, then strike out every volume that gets nothing.
- Match a machine per survivor, set it low, then verify from outside with a fresh nose.
Choosing the register last, setting the level low, and writing it down
The register comes last in this method on purpose, and that ordering is not an accident of layout. If you choose the fragrance first, every subsequent decision gets bent to justify it - you will find yourself wanting the makeup room scented because the register would be lovely in there. Do the volumes, do the striking-out, then choose one register for whatever survived.
The seven registers in the water-based Hotel Collection are each SOSA's own hotel-inspired interpretation, and SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand. Quiet Luxury is white tea, bergamot and cedar - hushed, polished lobby calm, and the default when the calculation has left you with a reception and a lounge doing several kinds of client work. White Tea Serenity is white tea, aloe and cedar - clean, weightless, spa-like, and the right answer for pale, daylight-heavy rooms. Forest Suite is cedarwood, vetiver and green leaves - grounding and biophilic green, which agrees with concrete, steel, plants and a double-height bay, and which reads as neutral to a mixed crew.
Tea Garden is jasmine, green tea and white tea - serene tea-and-jasmine calm, the bridal answer and the best floral for a long-dwell album room, because the jasmine sits inside the tea rather than on top of it. Warm Welcome is citrus, floral and sandalwood - warm, gracious hospitality, a threshold register. Old-World Glamour is amber, violet and woods - plush, evening-elegant, magnificent in a dark portrait room and heavy in a room where somebody sits for four hours. Lobby Bar is citrus, pepper and amber - bold, playful, after-dark, and in this vertical it belongs to a studio that hosts evening events.
SOSA does not publish comparative throw or longevity between the seven and this page will not invent it, because the variables that decide behaviour in your building are the ones you just measured: connected volume, ceiling height, ventilation rate, soft material and setting. Those swamp any difference between blends, which is precisely why the calculation comes first. If you want to choose properly, the pack of seven 15ml bottles at ₹1,799 lets you run one a week in your own reception and judge on day five rather than on a first impression.
Then the level, which the calculation informs but does not determine. Your dwell-time column tells you the ranking: the volume with the largest number of minutes on it gets the lowest dose in the building, every time. A consultation or album-selection room where two people sit for four hours choosing forty frames out of nine hundred is the lowest, and there is a good test for it - imagine the level you are considering, unchanged, at hour four, while they are deciding between two nearly identical frames of the same moment. If that sounds like a lot, it is a lot. Under-dose it and let consistency do the work; a whisper repeated on every visit is a signature, and a statement made once is an air freshener.
There is one client-specific thing worth designing around in a studio, because it comes up constantly and no calculation catches it. A bride visiting for a consultation is very often wearing her own fragrance, and sometimes she is trialling one for the wedding day and paying close attention to it. Your room has no business competing with that. It is her scent and her decision, and the studio's job is to be a pleasant background she never thinks about. That alone is a reason to run a consultation or bridal room lower than the arithmetic suggests it could carry.
Finally, put the whole thing on one sheet of paper and keep it: each volume, its cubic feet, its cubic metres, its dwell time in minutes, and either a machine and a written setting or the single word "nothing". That sheet is the calculation, and it is also the document that stops the studio drifting - because a year from now, when somebody asks why the makeup room does not have a diffuser, the answer is on the page rather than in somebody's memory.
| Scent | Why it suits the mood |
|---|---|
| Reception + lounge + corridor · 7,200 cu ft, about 204 m3 | 180 + 300 + 120 sq ft at 12 ft, open to each other, so one connected volume. Dwell time thirty seconds to forty minutes. This is the requirement. One machine: a Vaayu at ₹11,999 with enormous headroom, or a Megh at ₹3,499 if a water-based tank suits you. |
| Consultation room · 2,640 cu ft, about 75 m3 | 220 sq ft at 12 ft, behind a door that shuts for every session, so its own volume. Dwell time three to six hours, which makes it the lowest dose in the building. A Sukoon at ₹1,899 on the water-based Hotel Collection from ₹299, or a reed from ₹749 with nothing to plug in. |
| Double-height shooting bay · 20,000 cu ft, about 566 m3 | 1,000 sq ft at 20 ft. Forty-five per cent of the floor and fifty-eight per cent of the air in the building, and it gets nothing. A crew is in it for eight to ten hours and the client is being photographed rather than experiencing it. This single line is why the requirement is about a fifth of the building rather than all of it. |
| Makeup, changing room, kit store · 4,560 cu ft, struck out | 160 + 100 + 120 sq ft at 12 ft, about 129 m3 between them, all removed at step six. The styling station already has hairspray and setting spray winning in it and fragrance adds scent rather than removing odour; the changing room is a laundry and ventilation job; the store is a cupboard. Write them on the plan as deliberate blanks. |
So the calculation ends with a shopping list rather than a coverage figure, and in the worked example it is short. One machine for a 204 m3 connected front of house and one small unit for a 75 m3 consultation room, in a building holding about 975 m3 of air.
For the connected route the SOSA Vaayu at ₹11,999 is the commercial answer: waterless cold-air nebulising of undiluted oil, so 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, a 400ml tank, freestanding or wall or HVAC mounting, DC 12V / 1A at 5W so it needs a live socket, CE, RoHS and SGS, and a Bluetooth app and timer so the studio is scented in opening hours rather than overnight. At 204 m3 you are using a fifth of its rating, which is not waste - it is the headroom that lets you run it low, and low is the target.
If a water-based machine suits the building better, the ultrasonics are Boond at ₹899 for a small enclosed room, Sukoon at ₹1,899 for a normal reception or consultation room and Megh at ₹3,499 with a 6 litre tank for a room that runs all day. All three take the water-based Hotel Collection from ₹299, with 100ml refills at ₹999 and a seven-bottle 15ml pack at ₹1,799. They are cool-mist machines and they put moisture into the air, which is a real consideration in a coastal city in August. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine; the Vaayu ships with four hotel-inspired waterless blends as one of three bundle choices. If you are buying an ultrasonic now and expect to add a Vaayu later, say so on WhatsApp before you order.
Above the single-machine range sit the ducted units - 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 - which only enter the calculation if the building runs on one central air-handling system, and which will push fragrance into every room the supply air reaches, including the ones you struck out. Below it sit the SOSA reed diffusers, which are frequently the right survivor-room answer: Morning Freshness ₹749 with Malabar lemon, mint and eucalyptus; Garden Bloom ₹799 with British rose and night-blooming jasmine; Evening Calm ₹799 with Kashmir lavender and chamomile; Mountain Breeze ₹849 with Himalayan pine, sage and cedar; and Fresh Brew ₹849 with Coorg coffee and Kerala vanilla, which is lovely in a home and risky in a four-hour room. They last about 6 to 10 weeks, the 130ml is from ₹1,249 and refills are ₹2,399 for 300ml and ₹3,499 for 500ml.
If you would rather see the method applied than described, the sibling pages work it on specific buildings. How many scent machines a 2,000 sq ft photography studio needs runs the counting method end to end on a seven-volume plan. How to scent a 3,000 sq ft multi-room photo and video studio takes it into a building with sealed acoustic doors and a real HVAC question. And if the output of your calculation was a single number and you want to sanity-check it, is one commercial scent machine enough for a large photography studio is the yes-or-no version with the failure case attached.
The last thing to say about this calculation is what it cannot produce. It gives you volumes, a machine per volume and a starting level. It does not give you consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order or lead time, because SOSA does not publish any of those and they depend entirely on your run hours, your connected volume and your setting. Bring the completed sheet - volumes, cubic metres, dwell times, blanks and all - to SOSA on WhatsApp at +91 96192 18531 and that conversation can be had properly. 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.
- 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.

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.
