I get asked this in a very specific form. "We do about two hundred people a day - is that enough to justify it?" And the honest reply is a question back: how long does each of those two hundred stay, is there a room with a door around them while they do, and how many times did your front door open to deliver them? Because those three things decide whether a level can exist in your premises at all, and the headcount by itself tells me none of them.
Here is the part that inverts the assumption, and it is true rather than clever. A low-footfall, long-dwell business has a far better case than a high-footfall pass-through. A Baner clinic that sees fifteen people in a day, each of whom sits in one enclosed room for the better part of an hour, is a room in which a character can be established, held and recognised. A busy unit on a retail strip near the airport corridor that sees four hundred people, not one of whom is inside for four minutes, is a place where almost nobody is present long enough for the room to communicate anything at all - and where the door has cycled four hundred times, exchanging your air for the street's on each one.
Which is the second inversion. High footfall actively makes a room harder to hold, because footfall means door cycles. A coverage rating assumes one connected body of air; every time your door opens, part of that body of air leaves and is replaced. So if the headcount changes the answer at all, it changes it in the opposite direction from the one you were expecting. More people through the door is not more reason to buy. It is more reason to expect a gradient rather than a level, and to set lower rather than higher, because the person who receives every increment you make is the staff member standing nearest that door for eight to ten hours.
And before any of it, the ceiling, stated plainly because this is exactly the page where a fragrance seller would be tempted to imply otherwise. I will not tell you that a scent sells anything. No claim is made here about footfall, enquiries, conversion, sales, bookings, appointments, repeat visits, retention, spend or price tolerance, and none is implied. Ambient scent research supports improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. That is the whole of it. Notice in particular that footfall is not on that list in either direction: scenting does not raise it, and it is not the thing that justifies scenting.
Does a busy shop need a stronger setting than a quiet one? No, and the temptation to go up is the classic mistake. A busy premises has a door cycling all day and an occupancy that changes hour by hour, so what you get is a gradient rather than a level, and pushing output up does not convert one into the other - it moves the gradient outward and doses the people standing nearest the door. Those people are your own staff, in that air eight to ten hours a day, which is many times what any customer receives. A customer arriving from outside also gets the largest contrast anybody gets that day and needs the least. Busy is an argument for lower and for better placement, not for more.
So what should a high-footfall, short-dwell business buy? Usually depth rather than output. Find the volume in your premises that has edges and own that one: a doored consultation room, a fitting room, an office where people actually sit down, a washroom. Those are small - 100 sq ft at a 9 ft ceiling is 900 cubic feet, about 25 cubic metres - so they are answered by a Boond at ₹899, a Sukoon at ₹1,899 with the water-based Hotel Collection from ₹299, or a reed from ₹749. Accept a gradient at the front. Do not try to build a scent wall at a threshold, because it cannot be done at any price.
The second question is dwell, and it must be per person rather than in aggregate. This is where owners go wrong, because a headcount feels like it measures exposure and it does not. Four hundred people at three minutes and fifteen people at an hour are not the same business receiving the same room. The four hundred each receive a threshold: the light level as they come in from Pune daylight, the temperature contrast, how loud it is, whether the place looks ordered, and, somewhere down that list, a smell. The fifteen receive the room itself, continuously, for long enough that it stops being a note and becomes a property of the place. Ambient scent is a property-of-the-room medium, not a signage medium. It works on the person who stays, which is why the clinic, the studio, the consultation room, the salon chair and the waiting area are the natural homes for it, and why the pass-through is not.
The third question is whether footfall is working against you, and usually it is. Every door opening is an exchange you cannot count and should not try to. In a dry Pune April the door may be shut and the air conditioning running hard against highs around 35.6 to 37.9 degrees C in March, April and May, which is its own dilution - air that is being moved and exchanged faster carries whatever you put into it away faster, and that is the real reason people write to me in April saying the fragrance stopped working at three in the afternoon. In a wet July the door is shut against the rain, but now every one of those arrivals brings water in on soles, hems and an umbrella, and a high-cycle door in the wettest month of the year is a source problem that scales directly with your headcount. So footfall does change something. It changes how much entrance matting you need and how often somebody passes over it, which is a cleaning and cadence decision, not a fragrance one.
And the fourth question is who is in the air longest, which is never the customer. Whatever your footfall, your staff are there eight to ten hours a day, five or six days a week. They are the most exposed people in the building by a wide margin and they are also the least reliable judges of the level, because a nose adapts within about twenty minutes of walking in. So the cap on the setting is set by the people who cannot smell it, and the standing arrangement is written down rather than remembered: anyone on the desk may switch a named unit off without asking a manager, and a reported reaction is a recalibration signal rather than a tolerance problem. I make no health or allergy claim in either direction.
Put those four together and the answer to "at what footfall" becomes: at no footfall, and at any footfall, depending entirely on whether there is an enclosed volume, whether anyone stays in it, and whether somebody will hold a number. Send me the plan rather than the headcount - floor area, ceiling height, which doors actually shut, what the air conditioning is, and how long a person stays - on WhatsApp at +91 96192 18531, and you will get a straight answer. SOSA is a Pune business, so that is a local conversation rather than a shipped box. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Here is a five-minute exercise that replaces the footfall question with a useful one. Take your trading day and write down, honestly, the median time a customer is inside your premises, not the best case. Then write down the floor area and ceiling height of the largest space that is enclosed by doors that actually stay shut. Then write down how many times your front door opens in a day, to the nearest hundred, guessed rather than measured. Those three numbers tell me more than any headcount, and you can produce all three before lunch.
If the median dwell is under five minutes, the honest reading is that fragrance is a small part of a threshold and there are larger parts of that threshold to spend on first. What a person actually registers in four seconds, in rough order, is how bright it is compared with the street they just left, how the temperature changes, how loud it is, whether the place looks ordered and staffed, and then, faintly, what it smells like. In Pune that first item swings hard by season: somebody stepping in from hard April daylight at thirty-seven degrees experiences a different arrival from the same person stepping in on a wet grey morning in July, in the same shop, with the same lighting. That is not a fragrance variable at all.
If the median dwell is over twenty minutes and there is an enclosed room around it, the case is real, and it gets stronger the longer the sit gets - but in the direction of a lower setting rather than a bigger machine. Forty-five minutes of continuous exposure is a long time to be receiving anybody's decision about air. Calibrate for the person at minute forty and you will land well below what feels right on a walk-through.
One Pune refinement on the headcount itself, because the daily total hides a shape. Footfall in this city is not flat: near the Hinjawadi corridor, where the Rajiv Gandhi Infotech Park spreads over roughly 2,800 acres and around 240,000 people commute in daily, congestion concentrates around 08:00 to 12:00 and again from 17:30 to 20:00, and PMPML runs night bus routes. Any business sitting in that flow has an occupancy curve rather than a constant. The relevant tool is not a bigger number, it is the published Bluetooth app and timer, which lets the machine follow your curve instead of running flat across an empty room at three in the afternoon.
And the reflex to resist: when a busy room does not hold a level, the instinct is to add output. The busier the room, the more that instinct costs, because the people absorbing the increment are the ones who never leave.
The three variables that actually decide it, none of which is a headcount
Three variables decide this, and a headcount is not one of them. They are, in order of how decisively they settle the question: whether there is an enclosed connected volume, how long an individual person stays inside it, and whether anybody in your business will set a number and defend it. Everything else - including how many people come through your door - is either downstream of those or actively working against them.
I want to be precise about why the footfall question feels so natural, because the instinct behind it is reasonable. The reader is trying to work out whether there are enough people to justify the spend, which is a sensible way to think about a sign, a window display or a second member of staff. It fails for ambient scent for one specific reason: scent is received by presence, not by passing. A sign works on somebody walking past at speed. Air only works on somebody standing in it. So the quantity that matters is not how many people encounter your premises but how much time any one of them spends surrounded by it, and those two quantities are almost unrelated.
The second reason it fails is harder and more interesting. Footfall is not neutral with respect to the thing you are buying. Every visitor arrives through a door, and a door opening is your connected volume briefly ceasing to be connected to itself and becoming connected to a street. A premises with a very high headcount is therefore a premises in which the level you set is being partially reset all day. You can compensate with placement and with depth. You cannot compensate with output, and the attempt is what produces the over-scented shops that everybody in Pune has walked out of.
And the third reason is the ceiling, which is why this page cannot cheat even if it wanted to. If scent raised footfall, or conversion, or spend, then a headcount would be exactly the right variable and I could hand you a break-even. It does not, and I will not pretend otherwise. The honest ceiling is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes. Read it carefully: it is about how a space and its service are evaluated by somebody who is in it, and how well it is remembered afterwards. Both of those are functions of presence and consistency. Neither is a function of traffic. So the variable that matters was never the one in the question.
A coverage rating assumes one connected body of air. The Vaayu at ₹11,999 is published for approximately 1000 cubic metres of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly. 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 - are the same idea at building scale. All three numbers describe volumes that are bounded. Take away a boundary and the number describes nothing.
So do the arithmetic on your own premises, by hand, once. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A 300 sq ft reception at a 9 ft ceiling is 2,700 cubic feet, about 76 cubic metres. A 500 sq ft floor at 10 ft is 5,000 cubic feet, about 142 cubic metres. An 800 sq ft floor at 10 ft is 8,000 cubic feet, about 227 cubic metres. A 1,500 sq ft floor at 10 ft is 15,000 cubic feet, about 425 cubic metres. Note how far all of those sit below approximately 1000 cubic metres, and note the recurring honest finding of this whole bank: for most single-unit Pune businesses the machine is not the constraint, the setting is. You are not buying reach. You are buying the ability to hold a small amount evenly and to stop touching it.
Now count the doors, because doors are where volumes end. A 1,500 sq ft premises is not 425 cubic metres if it is a 900 sq ft front area plus two consultation rooms and an office whose doors stay shut. It is 255 cubic metres plus three separate small volumes, and the machine in the front area will not reach any of the three, at any setting, because scent does not travel through a closed door. That is not a weakness to be engineered around. It is the mechanism that makes zoning possible, and in a clinic it is exactly what lets you have a scented reception and completely unscented treatment rooms.
The failure case is the premises with no interior boundaries and one missing exterior one. One room, one open front, high traffic. I am asked about it constantly and the answer does not change: there is no volume, so there is no level, so there is no purchase that produces one. What there is instead is a gradient - strongest near the source, thinning outward, disappearing at the threshold - and a gradient is a legitimate thing to design for, but you design it by putting depth behind the source and by accepting the front is the street's. You do not design it by turning the number up. Turning it up gives you a shop where people can smell it on the pavement and not at the counter, which is the exact complaint that ends most of these experiments.
If that is your building, the money still has somewhere honest to go, and it is smaller money. A washroom at 40 sq ft and 9 ft is 360 cubic feet, about 10 cubic metres, and it is enclosed, and it is the single most reliable place in a small premises where a visitor forms an opinion about how the business is run. A reed at ₹749 lives there with no plug, no noise and nothing to switch off. That is not a consolation prize. For a high-traffic, short-dwell unit it is frequently the correct and complete answer.
Under about five minutes. The visitor is receiving a threshold, and a threshold is a compressed bundle of impressions delivered in the first four seconds: brightness compared with the street they just left, temperature contrast, noise level, whether the place reads as ordered and staffed, and then, well down the list, what the air smells like. Fragrance is a real part of that bundle but a small and late one, and it is the part that a short visit is least able to develop. This is also where owners are most tempted to compensate with strength, and it is the worst place to do it: the person walking in from a Pune street in April, out of hard dry heat with highs around 37 degrees C, is getting the biggest contrast anybody will get all day and needs the smallest dose. Meanwhile your own staff member at the counter is receiving everything you add, all day.
Ten to twenty minutes. Now the room has time to become a room. A collection point, a small store where people browse, a reception where somebody waits for an appointment. This is the band where a low, consistent, unremarkable level earns its keep, and where the word unremarkable is doing real work. If a customer thinks about the smell, it is set too high.
Thirty minutes to an hour and beyond. A clinic waiting area and consultation, a salon chair, a studio class, a fitting and alteration appointment, a long sales conversation about something expensive. This is the strongest case in the whole category, and it is also the case that demands the lowest setting. Those two facts arrive together and owners consistently accept the first and ignore the second. A person sitting in one small room for forty-five minutes receives everything continuously and cannot step outside. You calibrate for them at minute forty, not for the walk-through at minute one. Set it so that a member of staff who has been in the building since morning genuinely cannot find it, and so that the customer never has to think about it.
Now the arithmetic that makes the inversion concrete. Fifteen patients a day, each sitting for an hour in a 300 sq ft waiting area at a 9 ft ceiling - about 76 cubic metres - is a business in which the room is doing continuous work on somebody for most of the trading day, in a bounded volume, at a level you can hold. Four hundred visitors a day at three minutes each, in a 400 sq ft unit at 10 ft with an open front - nominally 113 cubic metres but in practice unbounded - is a business in which no individual is present long enough for the medium to work and the volume cannot hold a level anyway. Same city, same price list, opposite answers, and the headcount pointed the wrong way in both.
One more distinction that matters in Pune specifically. Dwell is not just duration, it is what the person is doing. Somebody standing at a counter with their attention on a transaction registers very little. Somebody sitting with nothing to do - a waiting area, a treatment chair, a fitting room - registers a great deal, because receiving the room is the only thing on offer. Waiting is the highest-attention state your premises produces, which is why the waiting area is where this medium is genuinely strong, and why it is also the room where an over-set level does the most damage.
And in a clinical setting the line is firm regardless of dwell: the default is a scented reception and waiting area with treatment rooms, procedure rooms and cabins left unscented, and the treating clinician decides what may be in the air of a room where treatment happens. That decision overrides everything on this page. No SOSA product is a medical device, a clinical product or an infection-control product.
Every person who enters your premises opens a door, and every opening replaces some of your air with the air outside it. You cannot count those exchanges, you should not try, and you certainly must not attempt to reduce them. I will never tell you to close a vent, shut down extraction, keep a door shut or reduce air exchange so that a fragrance lasts longer, in any phrasing. A well-ventilated premises is genuinely harder to scent and I would rather say so than sell you the opposite. Ventilation wins, always, and it should.
What this means practically is that a high-cycle door converts your level into a gradient, and the gradient has a shape you can work with if you stop fighting it. The zone within a few feet of the door is the street's, most of the day. The zone behind that is contested. The zone furthest from the door, ideally around a corner or behind a partition, is yours. So placement is the entire craft here, and it is free. Put the unit deep, away from the door, and equally away from the air conditioning supply airstream - a fragrance unit sitting in a supply airstream has its output picked up, carried off and thinned before it ever reaches the room, while a unit in a dead corner never reaches the room at all. In almost every busy premises I am asked to look at, placement beats output, and it costs nothing to move a machine.
The Pune seasons change the shape of the gradient rather than the principle, and this is where a generic article would stop and this page should not. From roughly June to October, with most rain June to September and July the wettest month, the door is shut against the rain but each opening delivers water as well as air: wet soles, wet hems, a folded umbrella that was open thirty seconds ago. At four hundred openings a day that is four hundred small deliveries of water into a conditioned room, and it is a source problem that scales directly with the headcount you were asking me about. The correct response is matting long enough for three or four strides, somewhere for umbrellas to drain that is not inside your smallest conditioned volume, and a mid-day pass over the entrance zone. None of that is a fragrance purchase and all of it changes your evening more than a machine would.
From mid-March to mid-June the picture reverses. The heat peaks in April and May with average highs around 37.9 and 37.3 degrees C, and - the part almost everyone gets wrong - it is dry, because Pune's humidity trough sits in exactly those hottest months. The door may be shut and the air conditioning running hard, which sounds like better conditions for holding a level and is not, because a system working hard is moving and exchanging air faster. Nothing is broken when the fragrance seems to thin at three o'clock in April; the room is turning its air over faster and your own nose has adapted since morning. Two rooms, two written settings, one building.
Finally, the human cost of getting this wrong, because it falls on one person. In a high-footfall premises somebody stands near that door all day. They receive the arrival contrast you designed, four hundred times, plus every increment anybody ever nudged. Your staff are in the air eight to ten hours a day - many times any customer's exposure - and they are the cap on the level, not the customers. Anyone on the desk can switch a named unit off without asking a manager, and a reported reaction is a recalibration signal, not a tolerance problem. Written down, not remembered.
- Measure the largest volume enclosed by doors that actually stay shut, in cubic metres.
- Write down the median minutes a customer is inside, not the best case.
- Guess the daily door openings - high numbers mean a gradient, so plan for depth.
- Name one person to hold the setting, and write a monsoon and a dry-season number.
The level a long sit takes, and what a four-minute visitor really receives
So set the level by dwell and cap it by staff exposure, and let the headcount tell you only where to put the machine.
The long-dwell room gets the lowest number in the building. That is counter-intuitive and it is the single most useful sentence on this page. A waiting area where somebody sits for forty minutes, a consultation room, a salon chair, a studio: the correct setting there is one that a person who has just walked in from outside can just about notice and that a person at minute forty has stopped noticing entirely because it never rose to the level of an event. If your test for "is it working" is that you can smell it when you walk in, you are testing with the wrong nose at the wrong minute.
The short-dwell front gets placement, not output. Deep, away from the door, out of the air conditioning supply airstream, and with a partition or a corner between it and the street if your layout offers one. Then accept the gradient. The four-minute visitor gets a threshold in which fragrance is a small late component, and the parts of that threshold with more leverage - how bright it is, how it sounds, whether it looks ordered - are not things I sell.
Now the register, which matters far less than the level and absorbs far more decision time. Seven in 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. For a long-dwell room the shortlist is dry and unsweet, because sweetness is what accumulates across forty minutes: White Tea Serenity is white tea, aloe and cedar, clean and weightless and spa-like, and reads as clean rather than as scented. Quiet Luxury is white tea, bergamot and cedar, hushed and polished, and is what I would run with one decision and no information. Forest Suite is cedarwood, vetiver and green leaves, the driest of the three and the one most likely to be received as part of the building rather than as somebody's decision.
For a threshold or arrival that people pass through rather than sit in, the calculus changes slightly and warmth becomes affordable, because nobody is accumulating it. Warm Welcome is citrus, floral and sandalwood, gracious and hotel-like at a door. Tea Garden is jasmine, green tea and white tea, the least insistent floral in the set. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and it belongs in an evening room rather than a daytime waiting area. Lobby Bar is citrus, pepper and amber, bold and after-dark, and it punishes long dwell harder than anything else in the collection.
I will not rank the seven against each other on measured throw or longevity. SOSA does not publish that comparison, and the variables that dominate - connected volume, ceiling height, how much air your building exchanges, how many people are in the room and the number you set - belong to your premises rather than to the blend. And the cheapest honest advice stands: one register held consistently already is a signature, because consistency makes a signature and uniqueness does not. Bespoke composition is a real SOSA service, discussed on WhatsApp rather than priced on a page, and it is the second answer rather than the first.
Whatever you set, write it down with a date, name one person who may change it, and give yourself two numbers for the year: a monsoon setting for the closed damp months of roughly June to October, and a dry-heat setting for mid-March to mid-June when the air conditioning is working hard and the room is turning over faster. Two settings, one blend, changed deliberately and not nudged.
| Scent | Why it suits the mood |
|---|---|
| Low footfall, long dwell, doored rooms · the strongest case in the category | Fifteen people a day who each sit for the better part of an hour in a bounded volume. This is where ambient scent genuinely works, and the correct response is the lowest setting in the building. Quiet Luxury, or White Tea Serenity where the room should read as clean rather than as scented. Calibrate for the person at minute forty, and let staff exposure cap it. |
| High footfall, short dwell, open frontage · the weakest case, and the most common | Four hundred people at three minutes with the street as part of your air. No bounded volume, so no level, and no machine at any price produces one. Own a doored room behind instead - a fitting room, an office, a washroom - and accept a gradient at the front. A reed from ₹749 or a Boond at ₹899 in the enclosed room is usually the whole sensible purchase. |
| High footfall, short dwell, but enclosed · a mall unit or a lobby with depth | Bounded, but with a door cycling and a public air system you must never ask anybody to alter. Placement is the whole craft: deep, away from the entrance, out of the supply airstream. Warm Welcome reads as a threshold register here. Set low, because the arrival contrast from a hot dry Pune afternoon is already doing most of the work. Sukoon ₹1,899 with the Hotel Collection from ₹299 for one room; the Vaayu at ₹11,999 for a connected floor. |
| Any footfall, no enclosed volume, live source · the answer is still no | If the entrance is wet through July, the linen is not drying, the air conditioner has not been serviced or a new fit-out is still off-gassing, the headcount is irrelevant. Fragrance adds scent and never removes it, so the order stands: source, then ventilation, then cleaning, then fragrance. Spend on matting, drainage, laundry cadence and an AC service, and ask again in November. |
The buying answer, sized by volume rather than by headcount. One enclosed room is usually a SOSA Boond at ₹899 or a SOSA Sukoon at ₹1,899, running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999 and 300ml also available; the pack of seven 15ml bottles at ₹1,799 is the sensible way to audition registers in your own air, judged on day five rather than on the first afternoon. A bigger room that runs all day may want the Megh at ₹3,499 with its 6 litre tank. A connected floor with real depth is the SOSA Vaayu at ₹11,999.
The Vaayu is the commercial machine: waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue, published for approximately 1000 cubic metres of connected air with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly, Bluetooth app and timer, 400ml tank, freestanding or wall and HVAC mount, DC 12V / 1A at 5W so it needs a live socket, CE, RoHS and SGS. In a business with an occupancy curve, the timer is most of what you are buying, because it lets the machine follow the curve rather than run flat across an empty room. Above it, 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. Two systems, and they are not interchangeable - the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. One honest note for a wet Pune month: the ultrasonics are water-based cool-mist units that put a small amount of moisture into the room they sit in, which is a plain design reason to prefer the waterless machine in July, and not a claim to control humidity, because no SOSA product does that.
Where this page connects to the rest: if what you actually want to know is whether the machine is worth the money for a small premium business, including the three situations where I tell people to keep it, that is the Rs 11,999 question answered with a willingness to say no. And if you already run reeds and are wondering what a machine would add, the difference is architecture rather than strength, which is set out in expensive reeds in a Pune clinic and what a commercial machine actually does differently.

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 - which in a boutique means the connected retail floor plus any viewing room that has a door of its own - 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
SOSA is a Pune business, so these are not pages I wrote from a desk somewhere else. I have stood in a Baner clinic in the second week of July and in a Kharadi tower in the middle of April, and the useful thing I can tell you is this: the locality on your signboard is not a technical variable. Nobody scents a postcode. What a locality name is actually shorthand for is a cluster of real things - how old the building is, whether the front is sealed glass or a door onto a pavement, what the air conditioning genuinely is, how many people come through, how long each of them stays, and what the room already smells of.
Which is why two businesses three doors apart can need completely different answers, and why the same business needs two different answers in July and in April. A Pune monsoon room and a Pune April room are not the same room. One is damp, closed up and slow; the other is dry, hot, and running its air conditioning so hard that whatever you put in the air is being moved and diluted faster than you think. That is a real difference and it belongs in the settings, not in the choice of blend.
The order never changes, though, and it is the least commercial thing I say: source, then ventilation, then cleaning, then fragrance. Fragrance adds a smell. It has never once removed one. If your unit smells of damp, or new paint, or last night's food, a machine will give you damp and fragrance - and most people find that worse than damp. Fix the thing making the smell, get air moving, clean what holds it, and then, if the room deserves it, give it a quiet character and hold it.
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. No SOSA product is an air-treatment device, an air purifier, a dehumidifier, a humidity-control product or an odour-removal product, and none makes any health, allergy, air-quality or occupational claim. No claim is made here about any effect on a customer, a patient, a purchase, a footfall figure or a business result. Nothing in this guide is clinical, facilities, HVAC, food-safety or building advice: in a clinical space the treating clinician decides what may be in the air, in a food business the kitchen and the applicable food-safety rules decide, and in any building the people responsible for its air and its maintenance decide - and their decision overrides every recommendation here. Descriptions of Pune's seasons and localities are general and qualitative; every figure about a specific building must come from that building. 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.
