Picture the day this page is written for. A newborn session at ten. A bridal consultation at two, with a couple who will sit for three hours choosing an album. A corporate headshot at five, in and out in forty minutes. Three completely different people, three completely different tolerances, one floor plan and one set of doors. The instinct is to try to make the building change character through the day, and that instinct is wrong, because a register does not clear out of a room on a schedule and no machine can un-scent a space between two bookings.
So the strategy is structural. Zone the building by connected air volume rather than by room name or by function. Set each zone for the most sensitive booking that will ever use it, not the average one - the ten o'clock newborn sets the level for that room, and the five o'clock headshot does not get a vote. Use the Vaayu's timer so that scenting follows opening hours instead of running unattended into an empty building. And accept the honest structural conclusion at the end: if one room must serve both a newborn and a bridal consultation, that room is unscented, and the reception carries the identity of the studio instead. That is not a loss. Reception is where identity belongs anyway, and every client's own preference still overrides the whole map.
Can I change the scent between bookings? No, and this is the point most strategies get wrong. A register does not clear out of a room on a schedule, and there is no setting that un-scents a space between a ten o'clock and a two o'clock. A diary can sequence bookings and build airing gaps; it cannot change what is in the air. Design the room for its strictest user and stop trying to make it switch character.
Should different client types get different registers? No. One register across the whole client route, held at different levels by zone. Different levels of a single register read as a building with a personality; different registers in adjoining rooms read as a building that has not decided what it is, and everyone feels the seam at the doorway without being able to say what changed.
Start with the drawing. Zone the building by connected air volume rather than by what the rooms are called. Take a realistic mixed-use studio. Zone A, reception and waiting, open plan: 400 sq ft at 12 ft is 400 x 12 = 4,800 cubic feet, and 4,800 divided by 35.3 is about 136 cubic metres. Zone B, the consultation and album room behind a door: 220 sq ft at 12 ft is 2,640 cubic feet, about 75 cubic metres. Zone C, the main shooting floor with a double-height bay: 900 sq ft at 18 ft is 16,200 cubic feet, about 459 cubic metres. Zone D, the small room that does newborn sessions in the morning and bridal consultations in the afternoon: 160 sq ft at 12 ft is 1,920 cubic feet, about 54 cubic metres. With every door open, all four are one body of air: 4,800 + 2,640 + 16,200 + 1,920 = 25,560 cubic feet, about 724 cubic metres.
That last number is instructive, because 724 m3 sits inside a single Vaayu's rating of approximately 1000 m3 of connected air. In other words the machine is not your constraint. Your constraint is the zoning decision, and if all your doors are open you have not made one - you have a single 724 m3 volume running at whatever level the strictest booking of the week can accept, which is very close to nothing.
Now the rule that turns the drawing into a strategy: each zone is set for the most sensitive booking that will ever use it, not the average one. Zone D holds a newborn on Tuesday morning; therefore Zone D is unscented, permanently, regardless of what else it holds. Zone B holds a couple for a three-to-six-hour album sitting; therefore Zone B runs the lowest active level in the building, because a register you like at ten minutes is a different thing at hour four. Zone C is a work floor where a crew stands for eight hours under lights; therefore Zone C gets nothing, which is the standing position in this bank. Zone A holds everybody for a while and is where identity belongs; therefore Zone A carries the register, held low, and it is the only zone that really needs a machine.
Then the diary, and its honest limits. What a diary can do is sequence: put the most sensitive booking first in the day before the building has accumulated anything, build airing gaps between sittings, keep the ten o'clock newborn away from the hour when the makeup station is busiest, and make sure nobody is cleaning with a strongly perfumed floor product twenty minutes before a maternity client arrives. What a diary cannot do is change what is in a room's air between a ten and a two. There is no timer setting that un-scents a space, and any supplier suggesting there is has sold you a story.
Which leads to the structural conclusion that most owners resist and then find liberating: if one room genuinely has to serve both a newborn session and a bridal consultation, it is an unscented room. Full stop. The bridal couple lose nothing they will ever notice, because the reception they walked through is where the studio's character is made, and a signature is built by holding one thing consistently rather than by having it in every room. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The mistake this page exists to prevent is the seasonal-menu approach: a bright citrus for corporate mornings, something floral for bridal afternoons, nothing on newborn days. It sounds thoughtful and it produces a building that smells of three things at once, because none of them clears out between bookings and they layer instead. Worse, it destroys the one benefit that is actually available. A returning client meeting identical air on visit four is the mechanism behind recall; a returning client meeting a different smell every time simply meets a room.
And write the map down, including the empty zones by name. A strategy that lives in the owner's head lasts until the first staff change. A strategy on one sheet of paper by the machine - zones, volumes, register, setting, hours, who owns the dial, which rooms get nothing - survives, which matters in a building where the person who set it up in March is not the person standing at the desk in December.
The zone map, the sensitivity rule, and what a diary can and cannot do
A mixed-client studio has three questions to answer and they are best answered in this order: what are my zones, what is the strictest thing each zone will ever hold, and what am I asking the diary to do. Everything else - registers, machines, prices - follows from those three and takes about ten minutes.
What makes this hard is that the natural way to think about a studio is by function, and function is exactly the wrong axis. "The newborn room", "the bridal room", "the headshot corner" are labels about bookings, not about air, and in most Indian studios two of those three are the same physical space at different hours anyway. Air does not know what is booked. It knows about doors, ducts, pressure and volume. So the first move in any real strategy is to stop naming rooms after clients and start measuring them as volumes with boundaries.
The second thing that makes it hard is a genuine commercial tension, and it deserves acknowledging rather than glossing. A studio that serves bridal and corporate work wants to feel like a place worth its prices, and ambient character is one of the cheapest ways to do that. A studio that serves newborn and maternity work needs rooms that are unscented as a standing default. Those two wants are not contradictory once you think in zones, and they are completely contradictory if you think in buildings. That is the entire argument of this page, and it is why the zone map comes before anything you might buy.
The third thing worth naming is the claim ceiling, because a strategy page invites overreach. Ambient scent is associated with improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. That is what is on the table and it is worth ₹299. There is no honest claim that a scenting strategy wins bookings, raises fees, improves conversion or increases referrals, SOSA does not make one, and a studio that designs its zone map expecting commercial returns has designed it for the wrong reason. Design it because a considered building is a nicer place to sit in, and because the rooms that should be empty deserve to be reliably empty.
Worked, for the studio from earlier. Zone A - reception and waiting, 400 sq ft at 12 ft: 4,800 cu ft, about 136 m3, ended by the front door on one side and a door to the corridor on the other. Zone B - consultation and album room, 220 sq ft at 12 ft: 2,640 cu ft, about 75 m3, ended by a door that is shut during every sitting. Zone C - main shooting floor, 900 sq ft with an 18 ft double-height bay: 16,200 cu ft, about 459 m3, ended by a large sliding door that is often open. Zone D - the small room, 160 sq ft at 12 ft: 1,920 cu ft, about 54 m3, ended by a door. And the total with everything open: 25,560 cu ft, about 724 m3.
Two things fall out of that table immediately. First, the double-height bay is more than half the air in the building, which is invisible on a floor plan and obvious in cubic metres; anybody sizing this studio by square footage alone would get it badly wrong. Second, the whole floor at 724 m3 is inside one Vaayu's approximately 1000 m3 rating, which tells you the machine was never the hard part. The hard part is deciding which of those four volumes is scented and then making the boundaries real.
Making them real is the same short checklist as everywhere else in this section, and it is worth walking rather than assuming. A door that is shut as the normal state is a boundary; a door that is "usually shut" is an opening with a good excuse, and a sliding door to a shooting floor that stands open all day is not a boundary at all - which means Zone A and Zone C are one 595 m3 volume for most of the week unless somebody closes it. A shared return grille joins two rooms through the ducting regardless of every closed door between them, so find out which rooms are on which circuit before you commit. A corridor touches everything, which is why the machine must never live in it even though the corridor has the spare socket. And placement inside a zone matters: away from supply and return grilles, away from the doorway to any zone you are protecting, out of the path of any fan.
Then write the map out properly, on one sheet, and pin it next to the machine rather than filing it. Zone name, cubic metres, register, setting, hours, who owns the dial. And - the column studios always leave off - the zones that get nothing, named individually with the word written against each. An empty zone that has been decided survives a change of staff. An empty zone that is merely empty acquires a plug-in in month seven from somebody being helpful.
Apply it and the answers arrive quickly. Zone D holds a newborn session on Tuesday morning, therefore Zone D is unscented - permanently, on Saturday afternoon as well, whatever else is booked into it. Zone B holds couples for three-to-six-hour album sittings, therefore it runs the lowest active level in the building; a register that is lovely for ten minutes is a different proposition at hour four, and by hour four nobody is annoyed, they are simply ready to leave. Zone C is a work floor where a crew is on their feet for eight or ten hours, therefore it gets nothing - the best opportunity in a photography studio is reception, consultation, bridal and client lounges and waiting areas rather than the active shooting areas, and that is as true in a mixed-client building as anywhere. Zone A is the one zone where a register genuinely earns its place, and it is where the studio's identity lives.
Notice what the rule refuses to do. It does not average. A room used by a newborn on Tuesday and a corporate headshot on Friday is not set halfway; it is set for Tuesday. It does not let the most tolerant client vote. The headshot client at five would happily accept a level that would be wrong at ten, and the fact that they would accept it is irrelevant, because the room cannot tell which day it is. And it does not let you make exceptions for a big booking, because an exception is just the strict rule broken on the day it mattered most.
There is a second, quieter part of this rule that owners find harder: the strictest booking includes people you never hear from. A family sitting can include a pregnant relative who has mentioned it to nobody. A corporate group can include somebody who would rather not say anything in front of colleagues. A bridal party can include a grandmother with a strong preference and no wish to make a fuss. You cannot survey the people you are dosing, which is exactly why the level is set for the least tolerant person who could reasonably be in the room rather than for the ones who spoke.
And the standing overrides, both of which outrank the map. First, the client's own preference: if somebody says they would rather there was nothing, the answer is to switch it off or take it out of the room straight away, without explaining that the level is low. Second, your staff, who are in that air for eight to ten hours a day, five or six days a week, while a client gets three hours twice - they are the most exposed people in the building and a sensitivity report from any of them is a recalibration signal rather than a tolerance problem. Turn it down first, discuss it second.
One last point about registers, because mixed-client studios are tempted to solve this with variety. Run one register across the whole client route, at different levels by zone. Different levels of a single register read as one building with a personality. Different registers in adjoining rooms read as a building that has not decided what it is, and everybody feels the seam at the doorway even though nobody can name what changed. For a mixed-client studio there is a second reason: one register is the only version of this you can describe in a sentence when a client asks, and "the same thing in our waiting room all year, and nothing in the rooms behind that door" is a good sentence.
What they are not for is client types. There is no setting, on any machine at any price, that un-scents a room between a ten o'clock newborn and a two o'clock bridal consultation. A register does not clear out on a schedule; it is in the air and in the soft furnishings, and the soft furnishings hold and re-release it for a good while after the machine stops. Any strategy built on switching character between bookings will produce a room that smells of two things at once rather than of either, and it will do it while the owner believes the timer is handling it.
So what should the diary actually do? Four things, all of them free.
Sequence by sensitivity. Put the strictest booking earliest, before the building has accumulated the day. A newborn or maternity session at ten in a room that has been aired since eight is a different room from the same session at five after four sittings, a makeup station and a crew lunch. If your week has one newborn client and eleven other bookings, that client's slot is the one you protect.
Build airing gaps. Five minutes with the door open between sittings, the bin taken out of the building rather than emptied into another bin in the same room, cups cleared, and anything a client lay on sent to the laundry basket rather than folded back onto the pile. Set it once as a buffer in your booking system and stop renegotiating it every busy Saturday. And remember that fragrance adds scent and does not remove odour, so a room that smells of the day needs air and a laundry basket rather than a bigger dose - source, then ventilation, then cleaning, then fragrance, in that order, always.
Separate the noisy neighbours. The makeup and styling station is full of hairspray, setting spray, primer and somebody's own perfume by mid-morning, and those are strong volatiles that will win against anything. Do not schedule a maternity or newborn session for the hour when the styling area next door is at its busiest, and keep the door between them shut. Similarly, do not have the floors cleaned with a strongly perfumed product twenty minutes before a sensitive booking - a fragrance-free zone includes the mop.
Fix the hours the machine runs. Opening hours only, written on the sheet with the rest of the map, with one named person able to change it. And never the reverse trick: you do not close vents, cut extraction or leave a room to stand so that a fragrance lasts longer between bookings. A well-ventilated studio is harder to scent, and that is the right trade in a building that has a newborn in it on Tuesday.
- Measure every zone: area x height = cu ft, divided by 35.3 = cubic metres.
- Write the strictest booking each zone will ever hold, and set the zone for that.
- Pick ONE register for the client route and note the level for each zone.
- Set the timer to opening hours, then sequence sensitive bookings early with gaps.
One register across the map, and the room that has to stay empty
With the map drawn, the register choice is one decision for the whole client route rather than one per client type. From the water-based Hotel Collection - each SOSA's own hotel-inspired interpretation, with SOSA independent and not affiliated with, endorsed by or connected to any hotel brand - the mixed-client answer is almost always Quiet Luxury: white tea, bergamot and cedar, hushed and polished, and the register least likely to feel wrong to whoever happens to be booked that day. That is precisely the test in this building, because the same reception holds a newborn family at ten, a bridal couple at two and a company's finance director at five.
The alternatives, honestly placed. White Tea Serenity is white tea, aloe and cedar, clean and weightless, and it is the lightest-reading of the seven, which makes it a good choice if your building leans pale, minimal and daylight-heavy or if you simply want the smallest possible presence. Forest Suite is cedarwood, vetiver and green leaves, grounding and green, and it reads as structural rather than decorative, which suits concrete, plants and a warehouse shell and tends to be read as neutral by a mixed crew. Warm Welcome is citrus, floral and sandalwood, gracious at a threshold, and it fits a studio whose positioning is family and hospitality, kept low. Tea Garden is jasmine, green tea and white tea, the floral that behaves because the jasmine sits inside tea, and it is the bridal-leaning answer if your work is mostly weddings. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush is a great deal at hour four in an album room. Lobby Bar is citrus, pepper and amber, bold and after-dark, and in this vertical it belongs only to a studio that hosts evening events.
Do not rank these on throw or longevity, because SOSA does not publish that comparison and nobody can give you one that survives contact with your own building. What decides how a register behaves in Zone A is the 136 m3 of air, the ceiling height, the ventilation rate, how much soft material is in the room and what level you set - and those swamp any inherent difference between one blend and another. Try them in your own air instead: the pack of seven 15ml bottles at ₹1,799 exists for exactly that, one register per week, judged on day five rather than on the first afternoon.
Now the levels, zone by zone, which is where the strategy actually lives. Zone A, reception and waiting at 136 m3: the register, held low, set for somebody arriving from the street with a clean nose. This is the only zone in the building that really needs a machine. Zone B, the consultation and album room at 75 m3: the lowest active level in the building, or nothing, because this is a three-to-six-hour room and a bride is often wearing her own fragrance and may be trialling one for the wedding day - the room's job is to be a background she never has to think about. Zone C, the shooting floor at 459 m3: nothing. It is a work floor, the crew is in it for eight hours, and the client's attention is entirely on being photographed. Zone D, the small room at 54 m3: nothing, permanently, because a newborn session uses it on Tuesday morning.
That last line is the honest structural point of the page and it is worth sitting with. If one room must serve both a newborn and a bridal consultation, it is an unscented room, and the reception carries the identity instead. Owners resist this because it feels like giving something up in the room where the money is decided. In practice the couple choosing an album have already walked through your reception, sat down, been given tea, and formed their impression of the building; what they meet in the album room is your work on a screen and your attention. A signature is made by holding one thing consistently in one place, not by having something everywhere, and a maternity client who comes back for the newborn session, the six-month and the first birthday will meet that same reception four times.
Two more rooms that belong on the map as permanently empty. The makeup and styling area, which by mid-morning already holds hairspray, setting spray, primer and somebody's perfume - strong volatiles that will win, so anything added there makes a third smell rather than a blend. And the changing area, which is a laundry and ventilation job. Write them down with the word "nothing" against each, and every client's own preference still overrides all of it, immediately and without needing a reason.
| Scent | Why it suits the mood |
|---|---|
| Zone A: reception and waiting · 400 sq ft at 12 ft = 136 m3 | The only zone that really needs a machine, and where the studio's identity lives. One register, held low, set for a person arriving from the street rather than for you at four in the afternoon. In a building that also does maternity and family work, remember that partners and grandparents sit here for the whole session, so dose it like a lounge rather than a threshold. A Sukoon at ₹1,899 with the Hotel Collection from ₹299 covers it. |
| Zone B: consultation and album room · 220 sq ft at 12 ft = 75 m3 | The longest sitting in the building at three to six hours, so the lowest active level or nothing at all. A register you love at ten minutes is a different thing at hour four. A bride is often wearing her own fragrance and may be trialling one for the wedding day, and the room's job is to be a background she never thinks about. Keep the door shut during sittings, which is what makes this a separate 75 m3 volume in the first place. |
| Zone C: the shooting floor · 900 sq ft at 18 ft = 459 m3 | Nothing. It is a work floor where a crew stands for eight or ten hours under lights and the client's attention is entirely on being photographed. It is also more than half the air in the building, which square footage hides and cubic metres reveals. If the sliding door to reception stands open all day, Zone A and Zone C are one 595 m3 volume and reception is being dosed into a room that should have nothing. |
| Zone D: the room that does two jobs · 160 sq ft at 12 ft = 54 m3 | Newborn at ten, bridal consultation at two. Set for the strictest booking it will ever hold, which makes it permanently unscented - on Saturday afternoon as well, whatever else is in the diary. No timer un-scents a room between two bookings, so this is a structural decision rather than a scheduling one, and the reception carries the studio's character instead. |
The buying answer follows the map rather than the building. In the worked example only Zone A is scented, at about 136 m3, and that is a SOSA Sukoon at ₹1,899 running the water-based Hotel Collection from ₹299, with 100ml refills at ₹999. A smaller enclosed reception is a SOSA Boond at ₹899. A large front-of-house that runs all day without anybody free to top it up is where the SOSA Megh at ₹3,499 earns its 6 litre tank. And a reed diffuser from ₹749 remains a perfectly serious answer for one corner, with no plug, no noise and nothing to switch off - Morning Freshness at ₹749, Garden Bloom at ₹799, Evening Calm at ₹799, Mountain Breeze at ₹849 and Fresh Brew at ₹849, lasting about 6 to 10 weeks, 130ml from ₹1,249 and refills at ₹2,399 for 300ml and ₹3,499 for 500ml.
The SOSA Vaayu at ₹11,999 is the right machine when a mixed-client studio's scented zone is genuinely large and connected - a front-of-house that runs to several hundred cubic metres, or a floor where reception, corridor and lounge are open to each other by design. Waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue, which is why it suits a building with equipment and wardrobe in it. 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 and HVAC mounting, DC 12V / 1A at 5W so it needs a live socket, CE, RoHS and SGS. And the Bluetooth app and timer, which in this building are the whole reason to choose it: scenting confined to opening hours, and one tap to switch everything off from behind the desk when a client asks.
Two systems, not interchangeable. The ultrasonics - Boond, Sukoon and Megh - are water-based cool-mist machines that put moisture into the air. The Vaayu and the ducted machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - run waterless nebulising oil, and the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. One caution specific to a mixed-client building: ducted scenting distributes through the same system whose return grilles join rooms together, so if any permanently unscented zone shares a circuit with the zone you want to scent, ducted is the wrong choice and that conversation should happen before anybody quotes. Ordinary studio prudence applies wherever a machine ends up - away from open equipment cases and the spot where lenses get changed, not pointed at anything you care about, and high and out of reach with no cable across the floor in a building children come to. That is prudence and housekeeping, not a protection claim, and SOSA publishes none.
To go deeper on the parts this page compresses: the mechanism behind every zone boundary, and the four gaps that quietly rejoin two of them, is how to create fragrance-free zones inside a photography studio. The arithmetic and shopping list for doing the reception and nothing else is can I scent only the reception of a maternity and family photography studio. If children are a large part of your mix, read should children's photography studios use strong fragrance. And the free half of all of it - airing on a schedule, the fresh-air setting and the laundry rota - is how to keep a family photo studio feeling fresh without heavy fragrance.
SOSA does not publish consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or lead time, and no page should invent them, because they depend on run hours, connected volume and setting - all of which are yours. Send your floor plan with ceiling heights, a note of which doors genuinely stay shut and a list of the client types who share each room, to WhatsApp at +91 96192 18531, and you will get a zone map back rather than a quotation. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition - a scent made only for your studio - is a real SOSA service discussed there rather than priced on a page. Though for a mixed-client studio the cheaper honest answer usually holds: one of the seven registers, held consistently and low in the reception for a year, already is a signature, because consistency makes a signature rather than uniqueness.
The SOSA scenting range
SOSA sells two different systems and one of the commonest mistakes is mixing them up. Size by the connected air volume of the room you are actually scenting - floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres. A door that stays shut ends one volume and begins another.
| Machine | System | What it is for | Price |
|---|---|---|---|
| SOSA Boond | Ultrasonic · water-based | A small desk or corner unit for one enclosed room - runs the water-based Hotel Collection | ₹899 |
| SOSA Sukoon | Ultrasonic · water-based | A larger ultrasonic for a reception or consultation room - Hotel Collection from ₹299 | ₹1,899 |
| SOSA Megh | Ultrasonic · 6L tank | A large-tank ultrasonic for a bigger lounge that runs all day | ₹3,499 |
| SOSA Vaayu | Waterless cold-air nebulising | The commercial machine - approx 1000 m3 of connected air, Bluetooth app and timer, no water and no humidity | ₹11,999 |
| SOSA Aangan | HVAC nebulising | Ducted scenting for approximately 8,000 to 10,000 sq ft | ₹25,999 |
| SOSA Meenar | HVAC nebulising | Ducted scenting for approximately 12,000 to 18,000 sq ft | ₹38,500 |
Two systems, and they are not interchangeable. The ultrasonics - Boond, Sukoon and Megh - run the water-based Hotel Collection from ₹299. Vaayu and the HVAC machines run waterless nebulising oil; the ₹299 water-based bottle never goes into a Vaayu. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is independent and not affiliated with any hotel brand. A portion of every order supports girl-child education through Nanhi Kali.
- Vaayu ₹11,999 - waterless cold-air nebulising, approx 1000 m3 connected air, Bluetooth app and timer, 400ml tank, freestanding or wall / HVAC mount, DC 12V / 1A, 5W, mains powered, CE / RoHS / SGS.
- Aangan ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar ₹38,500 for approximately 12,000 to 18,000 sq ft - both ducted into HVAC.
- The ultrasonics - Boond ₹899, Sukoon ₹1,899, Megh ₹3,499 - run the water-based Hotel Collection from ₹299, with 100ml refills at ₹999.
- Not published, and therefore never stated on this page: consumption rate, refill frequency, monthly running cost, machine lifespan, installation lead time or any minimum order. Those go to WhatsApp +91 96192 18531.
Versailles
A photography studio sells a feeling before it sells a photograph. A couple sitting on your sofa choosing an album is doing something emotional, and they are doing it in your air for three or four hours. That is a long time to be in a room, and it is the reason I keep telling studio owners to go lower than they think.
The mistake I see is scenting the whole studio at one level. A reception is a thirty-second room and can carry a little presence. A consultation lounge is a three-hour room and needs a whisper. A newborn or maternity room should usually have nothing at all, and I would rather say that plainly than sell a second machine.
And the unglamorous part first: fragrance adds scent, it does not remove odour. If the studio smells of hairspray, of last night's crew dinner or of a room that has been shut since Sunday, scent laid on top makes a third smell. Find the source, air the room, clean it - and then, when the air is honest, give it a signature.
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.
