The first six questions are about your own building, and you have to answer them before a supplier can help you at all. What is the connected volume of the room I actually want scented? Which doors stay shut during a working day? Where is the nearest live socket? Is the air conditioning on fresh air or recirculating? Which rooms must stay unscented? And who, by name, will own the setting once the machine is installed? Nobody selling you anything can answer a single one of those, and every one of them changes what you should buy.
Then, and only then, the supplier questions - and they are shorter and blunter than you expect. What connected air volume is this rated for. Which system is it, and what fragrance does it take. Can it run on a timer. And, the one that separates honest suppliers from confident ones: which of these figures is genuinely published, and which is being estimated for me right now?
That last question is where this page ends up, and it includes some awkward disclosure about SOSA. Consumption, refill frequency, running cost, machine lifespan, minimum order and lead time are not published, so they are conversations on WhatsApp rather than numbers on a page. A supplier who gives you a confident monthly figure without asking your run hours and your connected volume has guessed, and you should treat the guess as information about the supplier rather than about your studio.
What is the single most important number? Connected air volume, and the word doing the work is connected. Every coverage rating assumes one joined body of air, and a machine cannot push scent through a closed door. A 500 sq ft reception and lounge at 12 ft is 6,000 cu ft, about 170 m3 - but only if the two rooms are genuinely open to each other. If the lounge door shuts for every consultation, you have two volumes and one rating tells you nothing about the second.
What should make me suspicious of a supplier? A confident monthly running cost, refill frequency or consumption figure produced without asking about your run hours, your connected volume and your setting. Those three variables are yours, they swamp everything else, and nobody can know them from a phone call. SOSA does not publish consumption, refill frequency, running cost, lifespan, minimum order or lead time, and routes all of it to WhatsApp at +91 96192 18531 instead of guessing.
One: what is the connected volume of the room I actually want scented? Not the studio's total square footage - the volume of the specific body of air you are trying to fill. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A 500 sq ft reception at 12 ft is 500 x 12 = 6,000 cu ft, and 6,000 / 35.3 is about 170 m3. Studios are rarely 10 ft; most are 12 to 16, and a double-height bay can be 18 to 22, so measure rather than assume.
Two: which doors stay shut during a working day? Not which doors exist - which ones are closed while people are working. A machine cannot push scent through a closed door, so every shut door ends one volume and begins another. This single question is the most common reason a correctly specified machine disappoints, and you can answer it in ten minutes with a floor plan and a pen.
Three: where is the nearest live socket? This sounds trivial and is not. The SOSA Vaayu runs on DC 12V / 1A at 5W and is mains powered - it needs a live socket, and it needs one in a sensible position rather than behind the sofa the client sits on. If the only free socket is in the corridor, you will be scenting the corridor and hoping the rest leaks, which is a placement problem no rating solves.
Four: is the air conditioning on fresh air or recirculating, and where are the return grilles? A split unit stirs one room and joins nothing. A ducted system can join rooms that look separate on the plan and can also pull scent straight out of the room you meant to fill. If you already have a room that smells right next to a room that smells of nothing, look for the return grille before you conclude you need a second machine. And whatever you find, never reduce air exchange or close vents so fragrance lasts longer - a well-ventilated studio is genuinely harder to scent, and that is a good problem solved by placement and level.
Five: which rooms must stay unscented? Decide this before you buy, not after. The active shooting sets, the makeup and styling area, the equipment store, and a newborn photography room, which should be fragrance-free without hedging. Mark them on the plan, because their position relative to doors and grilles determines whether staying unscented is even achievable.
Six: who owns the setting? One named person, or it drifts. Everybody who works in a building goes nose-blind to it within minutes, so a level three people can adjust is a level that will be moved on quiet afternoons by reasonable people and never recorded.
Answer those six and any competent supplier can size you in one message. Answer none of them and the best supplier in India can only guess. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Here is the practical way to do it. Print your floor plan. Walk it once with a tape measure for ceiling heights, once with a pen marking every door that is actually shut during a working day, and once marking every live socket and every air-conditioning return grille you can find. Then write dwell time in minutes on each room - thirty seconds for reception, three to six hours for the consultation and album rooms - and cross out the rooms that will get nothing. That marked-up plan is worth more than every specification sheet you will read, and it is what you should send to a supplier instead of a question about coverage.
And treat the exercise as diagnostic rather than as procurement. A fair number of studios who do this properly discover that the room they wanted to scent is not one volume, or that the smell they were trying to fix is coming from a source that fragrance will not touch, or that the honest answer is a reed diffuser at ₹749 in one corner rather than a machine at all. That is a good outcome, it costs nothing to reach, and it is why the building questions come first.
Six questions about your own building, before you ask a supplier anything
A scent machine is one of the few purchases where the specification sheet tells you almost nothing useful on its own, because every number on it is conditional on a building the manufacturer has never seen. A coverage rating is not a property of a machine in the way that a tank size is. It is a claim about how a machine behaves in one connected body of air of a given size, and the moment your building differs from that assumption - a shut door, a return grille, a double-height bay, a propped-open street door - the number stops describing your room.
So this page is a checklist, and it is deliberately uncomfortable for the person selling. The first section is six questions you answer yourself, with a floor plan and a tape measure, before you contact anybody. The second is four questions to put to any supplier, whoever they are. The third is the list of things nobody can honestly tell you, including SOSA, and how to tell when somebody is telling you them anyway.
One framing before the detail, because it saves money more often than any of the questions do. The first question is not which machine, it is whether. Fragrance adds scent and does not remove odour, so if the reason you are shopping is that the studio smells of something - stale air after a closed weekend, warm fabric after a nine-hour wardrobe day, hairspray from the styling corner, a crew lunch that went into the studio bin - then a machine is the wrong purchase and it will produce a third smell rather than a solution. Source, then ventilation, then cleaning, then fragrance. Every question below assumes you have already worked through that order and the air is honest.
It is also worth knowing what a machine will and will not do for the business, so the purchase is made against a real expectation. Ambient scent is associated with improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. It is not associated with bookings, enquiries, fees, footfall or retention, and if a supplier's pitch leans on any of those, that is the fifth question answering itself.
2. Which doors stay shut during a working day? Walk the plan and mark them, and be honest rather than architectural: the question is which doors are closed while people are working, not which doors exist. Every shut door ends one volume and begins another, because a machine cannot push scent through it. This is the question that decides whether you are buying one machine or two, and it is the single most common reason an owner tells me their diffuser stopped working. It had not. The consultation room door had been shut for every consultation since the day it was installed.
3. Where is the nearest live socket, and is it in a sensible place? Mains-powered machines need mains. The SOSA Vaayu runs on DC 12V / 1A at 5W and needs a live socket; it mounts freestanding, on a wall or into HVAC, but none of those options invents power. The practical failure is subtler than having no socket: it is having only one, in the wrong place, so the machine ends up in the corridor because that is where the plug was. Then the corridor is what you are dosing and the reception is getting whatever leaks through the doorway. Mark every live socket on the plan before you decide anything.
4. Is the air conditioning on fresh air or recirculating, and where are the return grilles? This is the question that explains most "it works in one room and not the next" complaints. A split unit stirs the room it is in and joins nothing. A ducted system on recirculation can carry scent between rooms that look separate on a drawing, which is sometimes useful and sometimes exactly the problem. Return grilles pull air - and fragrance - out of the room you were trying to fill. Find them, note them, and place the machine away from them. And never, in any phrasing, reduce air exchange, close vents or switch off extraction so the fragrance hangs around longer. A well-ventilated studio is harder to scent and that is a good problem; you solve it with placement and level.
5. Which rooms must stay unscented, and are they physically separable? Decide before you buy. The active shooting sets get nothing, because they are work rooms where the crew spends eight or ten hours and the client's attention is entirely on being photographed. The makeup and styling area gets nothing, because hairspray, setting spray, primer and a hot tool are already winning in there and a diffuser on top makes a third smell. The equipment store and changing room are housekeeping and laundry jobs. And a newborn photography room should be fragrance-free, without hedging - pregnant clients are commonly scent-sensitive and nausea is ordinary in pregnancy, which is a plain reason to keep those rooms unscented and is not a basis for any health or safety claim in either direction. Then check the geometry: a room only stays unscented if it has a door that shuts and is not downstream of a supply grille fed from the scented volume.
6. Who owns the setting? Name the person before you buy the machine. Everybody in the building goes nose-blind to it within minutes of arriving, so a dial that three people can reach is a dial that gets nudged on quiet afternoons by reasonable people who genuinely believe it has faded, and never recorded. One owner, one written setting, and a rule that a staff sensitivity report comes down first and gets discussed second - staff are in that air eight to ten hours a day and are the most exposed people in the building.
Answer those six on a marked-up floor plan and send the plan. Any competent supplier can size you from it in a single message, and you will have removed every variable they would otherwise have had to guess at.
2. Which system is it, and what fragrance does it take? There are two and they are not interchangeable, and buying the wrong bottle for the right machine is the commonest ordering mistake in this category. Ultrasonic machines are water-based cool-mist units that put moisture into the air - Boond ₹899, Sukoon ₹1,899, Megh ₹3,499 - and they run the water-based Hotel Collection from ₹299, with 100ml refills at ₹999. Waterless nebulising machines run undiluted oil in cold air with no water, no humidity and no wet residue - Vaayu, Aangan, Meenar. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. Ask which system you are being sold, what it consumes, and whether the fragrance you are choosing today will still be usable if you move up a machine next year.
3. Can it run on a timer? Ask this even if it sounds like a convenience feature, because it is not. A machine without scheduling gets switched on by whoever opens and switched off by whoever remembers, which means your studio is scented for inconsistent hours and sometimes overnight into an empty building. The Vaayu has a Bluetooth app and timer, and in a studio that is the feature that turns run hours into a setting rather than a habit. It also means the level you carefully calibrated is the level a client meets at ten in the morning rather than whatever accumulated since three.
4. Which of these numbers is genuinely published, and which are you estimating for me right now? This is the question, and you should ask it directly, because the answer is more informative than any specification. Published figures are things like price, tank capacity, power draw, mounting options, certifications and the coverage rating. Estimated figures are almost everything to do with running the machine in your particular building. A supplier who separates the two honestly is a supplier who will still be useful to you in a year. A supplier who answers everything with equal confidence has told you that some of those answers are invented.
Two supporting questions worth adding for a studio specifically. Ask what the machine physically is and where it can go, because a studio has equipment and wardrobe in it: the Vaayu takes a 400ml tank, mounts freestanding, on a wall or into HVAC, and carries CE, RoHS and SGS. And ask about placement prudence rather than protection claims - keep any machine away from open equipment cases and the spot where lenses get changed, and do not point a mist machine at anything you care about. If a supplier tells you their machine is certified safe for photographic equipment or that it protects your gear, that is a claim SOSA does not make and would not make, and you should ask to see where it is published.
And one question you should not bother asking, because no honest answer exists: which fragrance is strongest or lasts longest. SOSA does not publish comparative throw or longevity between the seven registers, and any ranking that survives contact with your particular room would have to account for your volume, ceiling height, ventilation rate, soft furnishing, setting and run hours - which are all yours. A supplier who ranks them in a building they have never stood in is guessing at your expense.
There are six figures buyers ask for constantly, and SOSA publishes none of them: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity and lead time. They are not withheld to force a conversation. They are not published because any single number for them would be false for most of the people reading it, and a false number in a buying decision is worse than an honest absence.
Take running cost, since it is the one everybody wants. What actually drives it is three things, and all three are yours rather than the supplier's. Run hours: a studio open six hours a day, four days a week, is a completely different consumer from one running twelve hours a day, seven days. Connected volume: filling 85 m3 is not the same job as filling 340 m3 or 595 m3, and the arithmetic that produces those numbers is your floor plan multiplied by your ceiling height. Setting: the difference between a level set for a client arriving from the street and a level set by an adapted nose at four in the afternoon is not marginal, and it is the variable buyers control most and think about least. Ventilation rate and how much soft material is in the room move it again.
So: a supplier who gives you a confident monthly figure without asking your hours and your volume has guessed. Not lied, necessarily - guessed, from an average of buildings that are not yours, and then presented the guess with the same confidence as the tank size. The tell is the sequence of the conversation. An honest sizing conversation starts with questions about your building and produces a range with conditions attached. A guess arrives immediately, as a single number, usually a tidy one.
The same applies to refill frequency, which is really consumption wearing a different hat, and to lifespan, which depends on run hours and maintenance in ways nobody can forecast from a phone call. On minimum order quantity and lead time: SOSA does not publish either, bulk orders are welcome with no numbers, tiers or minimums attached to that sentence, and custom label or logo on product is available. Bespoke composition - a scent made only for your studio - is a real service, discussed with no price, no minimum, no lead time and no process detail on any page. All of it goes to WhatsApp at +91 96192 18531.
Now the other half: what a supplier should be able to publish without hesitating, and what you should be able to check on a product page rather than take on trust. Price. System type - water-based ultrasonic or waterless nebulising. Tank capacity. Power requirement and whether it needs mains. Mounting options. Certifications. The coverage rating and the assumption behind it. Fragrance compatibility. Whether it has scheduling. If any of those is vague, the vagueness is the answer.
Three answers that should make you slow down, whoever you are talking to. The first is any suggestion that a machine removes, neutralises, absorbs, sanitises or purifies odour - fragrance adds scent and does nothing of the kind, and a supplier who claims otherwise is either mistaken or hoping you are. The second is any suggestion that you close vents, reduce extraction or keep a room shut so the fragrance lasts longer; that is bad advice about your building offered to make a product look better. The third is any claim tying scent to bookings, enquiries, fees, footfall, referrals or retention. The honest ceiling is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes, and that ceiling does not move because a machine costs more.
One last question to ask yourself rather than anybody else, and it is the cheapest question on this page: am I solving a smell problem or adding a signature? If the studio currently smells of something, you are solving a source problem and a machine will make it worse by adding a second smell to the first. If the air is already honest and you want the room to feel considered and consistent, that is what a machine is for, and now every question above has a purpose.
- Fix source, ventilation and cleaning first - a machine adds scent, it removes nothing.
- Mark up a plan: ceiling heights, shut doors, live sockets, return grilles, dead rooms.
- Compute connected volume by hand: area x height, then cubic feet divided by 35.3.
- Ask which figures are published and which are being estimated for you right now.
What to ask a supplier - and what nobody can honestly answer
The fragrance question is the last one on the checklist rather than the first, and it should take about twenty minutes, because register is taste and level is what actually goes wrong. Still, there are three things to ask about fragrance before you buy a machine, and they are practical rather than aesthetic.
Which system does the fragrance belong to? The seven registers of the water-based Hotel Collection at ₹299 run in the SOSA ultrasonics - Boond, Sukoon and Megh - which are cool-mist machines that put moisture into the air. The Vaayu and the ducted machines run waterless nebulising oil instead, with no water, no humidity and no wet residue, and the Vaayu ships with four hotel-inspired waterless blends as one of three bundle choices. The ₹299 bottle never goes into a Vaayu or an HVAC machine. If you are choosing a register on an ultrasonic today and expect to move to a Vaayu when you take a bigger floor, say so before you buy so that nobody ends up with the wrong bottle.
Can I try it in my own room before committing? Yes, and you should. The pack of seven 15ml Hotel Collection bottles at ₹1,799 exists precisely so that a register gets chosen in your actual air rather than from a description. Run one at a time at a low setting and judge it on day five rather than the first afternoon; first impressions in fragrance are unreliable and day-five impressions are excellent. Most studios find the register they were excited about is the one they tire of.
Which register suits my room? Choose by standing in your own reception in daylight and asking what the materials are already saying, not from a note list on a phone. Quiet Luxury is white tea, bergamot and cedar - hushed, polished lobby calm, and the safest answer for a studio reception because it is neutral across client types. White Tea Serenity is white tea, aloe and cedar - clean, weightless and spa-like, for pale, minimal, daylight-heavy rooms. Forest Suite is cedarwood, vetiver and green leaves - grounding and green, for concrete, steel, plants and a warehouse shell. Tea Garden is jasmine, green tea and white tea - the floral that behaves in a long bridal sitting, because the jasmine sits inside the tea. Warm Welcome is citrus, floral and sandalwood, a threshold register for a warm, hospitable studio. Old-World Glamour is amber, violet and woods, plush and evening-elegant, right for a dark portrait room and heavy in a six-hour album room. Lobby Bar is citrus, pepper and amber, bold and after-dark, and belongs to an events floor. Each is SOSA's own hotel-inspired interpretation; SOSA is independent and is not affiliated with, endorsed by or connected to any hotel brand.
Then the level, which is the part the checklist should really be protecting you from. Dwell time sets the dose and a studio has several. Reception is a thirty-second to two-minute room and can carry a little presence. The consultation room, the bridal lounge and the album-selection room are three-to-six-hour rooms and take the lowest level in the building - imagine your chosen level unchanged at hour four while two people decide between two nearly identical frames, and if the honest answer is "that would be a lot", it is a lot. Set the level for a client arriving on a Tuesday morning into a building that has been shut, not for yourself at four on a Saturday, because your nose stopped reporting hours ago.
And the rooms you already marked as unscented on the plan stay that way. Active shooting sets, because they are work rooms and the crew is in them for eight or ten hours; the makeup and styling area, where strong volatiles are already winning; the equipment store and changing room, which are housekeeping jobs; and a newborn photography room, which should be fragrance-free without hedging. Pregnant clients are commonly scent-sensitive and nausea is ordinary in pregnancy, which is a plain reason to keep those rooms unscented and is not a basis for any health, safety or calming claim in either direction. This page makes none, and a client's own stated preference overrides everything written here.
One last fragrance question that belongs on a buying checklist and rarely appears on one: how will refills reach you, and whose job is it to order them? Not a lead time - that is not published - but a routine. A signature that goes missing for a fortnight because nobody owned the reordering is a signature that was not held that fortnight, and it is a far more common failure than choosing the wrong register. Put reordering on the same person who owns the setting.
| Scent | Why it suits the mood |
|---|---|
| Your building · only you can answer | Connected volume of the room you are actually scenting, which doors stay shut during a working day, where the nearest live socket is, whether the AC is on fresh air or recirculating and where the return grilles are, which rooms must stay unscented, and who will own the setting. Six answers on a marked-up plan, and any competent supplier can size you from them in one message. |
| The machine · the supplier should publish | Price, system type, tank capacity, power requirement, mounting options, certifications, coverage rating and the assumption behind it, fragrance compatibility and whether it runs on a timer. The Vaayu at ₹11,999 is waterless cold-air for approx 1000 m3 of connected air, 400ml tank, DC 12V / 1A 5W and mains powered, CE, RoHS and SGS. |
| The running of it · nobody publishes | Consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity and lead time. All driven by your run hours, your connected volume and your setting. A confident number offered before any question about your hours and your building is an average of somebody else's studio. |
| The answers that should worry you · whoever says them | That a machine removes, neutralises or purifies odour - it does not, fragrance only adds scent. That you should close vents or reduce extraction so it lasts longer - never do that. That scent will win bookings, fees or referrals - the honest ceiling is better evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. |
Once the checklist is answered, the shortlist writes itself, because the answer is decided by connected volume and by which system suits the room rather than by anything else.
If the volume you computed is one enclosed room - a small consultation room, a corner of reception, a viewing room - an ultrasonic is enough. The SOSA Boond at ₹899 handles a small enclosed room and the SOSA Sukoon at ₹1,899 a normal reception, both running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999. If that room runs all day and somebody keeps having to refill at lunchtime, the SOSA Megh at ₹3,499 and its 6 litre tank is the reason to spend the difference. Remember that these are water-based cool-mist machines that put moisture into the air, which is worth knowing in a room with equipment in it - ordinary prudence is to keep any machine away from open gear cases and the spot where lenses get changed, and not to point a mist machine at anything you care about. That is housekeeping, not a protection claim, and SOSA publishes none.
If your computed volume is a whole connected client route - reception, corridor and lounge genuinely open to each other, somewhere in the range of 170 m3 to 595 m3 by the arithmetic above - the SOSA Vaayu at ₹11,999 is the commercial answer. Waterless cold-air nebulising of undiluted oil: no water, no humidity and no wet residue, which is the whole reason it belongs in a studio with wardrobe and gear in it. It is rated for approximately 1000 m3 of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. It takes a 400ml tank, mounts freestanding, on a wall or into HVAC, runs on DC 12V / 1A at 5W so it needs a live socket - which is checklist question three, and this is where that question pays for itself - and carries CE, RoHS and SGS. The Bluetooth app and timer answer supplier question three directly.
If the premises are genuinely large and ducted, the HVAC machines are the honest answer rather than several freestanding 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. And if your checklist produced a room with no free socket, no appetite for a device and no need for scheduling, a SOSA reed diffuser from ₹749 is a legitimate answer rather than a consolation prize: no plug, no noise, nothing to switch off, lasting about 6 to 10 weeks. Morning Freshness ₹749 is Malabar lemon, mint and eucalyptus; Garden Bloom ₹799 is British rose and night-blooming jasmine; Evening Calm ₹799 is Kashmir lavender and chamomile; Mountain Breeze ₹849 is Himalayan pine, sage and cedar, the closest to a studio's woody register; and Fresh Brew ₹849 is Coorg coffee and Kerala vanilla, lovely at home and risky where somebody sits for four hours. The 130ml is from ₹1,249, with refills at ₹2,399 for 300ml and ₹3,499 for 500ml.
A note on the answer nobody sells you: sometimes the checklist produces "nothing yet". If question one shows the room is not one volume, if question three shows there is no sensible socket, or if the honest reason you are shopping is a smell that has a source, then the correct purchase this month is a laundry schedule and an open window at eight in the morning. Studios that do the free work first consistently need less machine than they expected, and several need none.
For the arguments this checklist assumes rather than makes: if you are wondering whether the room justifies what you charge, the premium-pricing page answers that question honestly and keeps products out of it for most of its length. If you are buying for more than one address, whether every location should smell the same explains why identical machines do not produce identical rooms and how to calibrate each one. And if the studio is not built yet, planning the scenting system at the design stage covers the questions above at the point where they are free to answer - doors, sockets and air handling on a drawing rather than in a finished building.
The honest close: SOSA does not publish consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or lead time. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition is a real service with no price, minimum, lead time or process detail stated on any page. Send your marked-up floor plan, your ceiling heights and your list of shut doors to SOSA on WhatsApp at +91 96192 18531 and the sizing conversation can start from your building rather than from a catalogue.
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.
