That reframing is the whole page, and it matters because of what it takes off the table. The machine is not faulty. The oil is not weak. The register has not "gone off". You have not been sold the wrong thing. The front of your shop is simply the hardest part of the building to hold a level in, and it is hardest for a reason that has nothing to do with fragrance: it is the part of your floor where the street is continuously part of your air. Once you accept that, the money and the attention move to where they can actually do something - which is everything behind the entrance.
Two things make this a Viman Nagar page rather than a generic one. The first is the neighbourhood's shape. This is a residential and retail area about half a kilometre south of Pune International Airport, nicknamed Airport City, with corporate offices, fine dining, mall-anchored retail and a notable hospitality cluster. If your own unit is one of the ones with a door onto a street or onto a mall concourse, the visits are typically short. A customer who is in your shop for ten or fifteen minutes, in a unit whose door opens every couple of minutes, is a very specific technical situation and it is the one this whole block of pages is about. The second is the season, which acts directly on the door: a Pune April, hot and - the counter-intuitive, verified part - dry, with the humidity trough falling in February to April, has your air conditioning running hard and the biggest possible difference between your interior and the street. A Pune July, mild and wet, has a much smaller difference across that threshold but brings water through it with every customer.
Three limits before the detail. I will never suggest reducing ventilation, closing a vent, propping a door shut or altering your building's or your mall's air handling so that a fragrance lasts longer, in any phrasing. The door, the entrance and the air handling belong to your landlord, your mall management and the people responsible for the building, and fragrance is never a good reason to touch them. Fragrance adds scent and does not remove odour; no SOSA product treats, filters, dries or purifies air. And the ceiling on what scent honestly does is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes - nothing about footfall, purchases or spend.
Should I buy a bigger machine or turn the output up? No on both counts, and this is where most of the wasted money in retail scenting goes. Turning up an ambient machine does not build a wall at the threshold; it raises the level everywhere behind the threshold - including the desk where a staff member stands for nine or ten hours - while the doorway still reads of street. You end up with an over-scented interior and an unchanged entrance. The fix is free and it is placement: move the unit deep into the volume you actually care about, out of the entrance airstream and out of any air conditioning supply airstream, then leave it alone for a fortnight before judging it.
How many door cycles does it take to matter? Fewer than you think, and you should count rather than guess. Four hundred openings across a ten-hour trading day is forty an hour, which is one every ninety seconds - and most owners guess low by a factor of two or three because they forget staff, deliveries and people who came in to ask a question. The air does not care why the door opened. Count one busy hour and one quiet hour, including everything, and you will know whether you have one room that behaves differently by the hour or two rooms that happen to share a floor. On a street-facing retail unit it is usually the second.
Then accept what a cycle actually is. Air moves through an open doorway because the two sides of it are not the same - different temperature, different pressure, whatever the street is doing at that moment - and it moves more vigorously the larger that difference is and the longer the door stays open. I am going to keep the physics qualitative on purpose, because the real rate in your unit depends on your door, your building, your street and the hour, and anybody who quotes you a number for it without standing in your doorway is inventing it. What is not qualitative is the consequence: each cycle is an exchange rather than a leak, and over hundreds of them the first stretch inside your entrance is substantially street air with some of yours mixed in, for most of the day.
Now do the arithmetic, because it turns a complaint into a plan. Take a shop of about 800 sq ft at a 10 ft ceiling. That is 800 multiplied by 10, which is 8,000 cubic feet, and 8,000 divided by 35.3 is about 227 cubic metres of air. Now measure the part you are complaining about. An entrance zone running the full 12 ft width of a shopfront and 8 ft deep is 96 sq ft, and at the same 10 ft ceiling that is 960 cubic feet, which is 960 divided by 35.3, about 27 cubic metres. Twenty-seven out of two hundred and twenty-seven is roughly one eighth of your shop. That eighth is the part the door owns and you do not. The other two hundred cubic metres is entirely yours, and it is where every rupee of your scenting budget should be aimed.
Run the same sum on a larger unit and the ratio improves rather than worsening. A 1,500 sq ft store at a 12 ft ceiling is 18,000 cubic feet, about 510 cubic metres, and the same 27 cubic metre entrance zone is now around one twentieth of it. Depth is the variable that saves you, and it is a property of your unit rather than of your machine. A deep shop with a busy door is an easy problem. A shallow one is a hard problem, and no machine converts the second into the first.
Then place the unit properly, which fixes more complaints than any upgrade. Three placement errors account for almost all of them. A unit near the entrance has its output pushed out and pulled in by every cycle, so the level swings all day and averages lower than the setting suggests - and it delivers the highest concentration exactly where your desk staff stand. A unit sitting in front of an air conditioning supply grille has its output picked up, carried away and thinned before it reaches anybody, then delivered wherever that air is going, which in a shallow shop is frequently straight back out of the front door. A unit in a dead corner behind a display never joins the room at all. The fix in all three cases costs nothing: move it deep into the volume you care about, out of both airstreams, roughly at standing head height rather than ceiling level if the format allows, and then leave it alone for a fortnight, because your own nose adapts within a day and only a stable judgement is worth having.
And the thing I will not do. I will not suggest that you prop the door shut, fit anything to the entrance, reduce ventilation, close a vent or ask anybody to change the air handling so that a fragrance holds better. If you are in a mall unit, the air handling is the mall's and the answer is even simpler: it is not yours, it is not mine, and it is not a fragrance question. A well-ventilated shop with a busy door is genuinely harder to scent than a sealed room, and that is a trade-off I will describe honestly rather than solve at the expense of your air. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, do the two walks. Walk in from the pavement and stop three times - just inside the door, in the middle of the floor, and at the deepest point a customer reaches - standing still for a full minute at each. Then do it in reverse, from the back of the shop out to the street. Those are five different experiences of the same room, and the one you have been using to judge your machine is almost certainly the first stop on the first walk, because that is where you stand when you arrive in the morning and where you stand when you leave at night. The doorway is the worst possible vantage point for assessing a shop's fragrance, and it is the only one most owners ever use.
The second exercise is the count, and it is the one that changes minds. One busy hour, one quiet hour, everything included. The ratio between them tells you something no product specification can: whether you have one room that behaves differently at different hours, or two rooms that happen to share a floor. In street-facing retail it is usually the second, and once you see it that way the gradient stops feeling like a defect.
Be careful about whose nose you trust, and be especially careful with the person at the desk. They have the strangest sensory day in the building - conditioned air, street air, conditioned air, hundreds of times over - which makes them very alert to a change and quite unreliable about an absolute level. They are also the most exposed person in the building and the cap on your setting, because they stand in that swing for nine or ten hours while a customer passes through it in four seconds. Anyone on the desk can switch a named unit off without asking a manager, that day, without justifying it. A reported reaction is a recalibration signal rather than a tolerance problem, and I make no health or allergy claim in either direction.
And here is the compensation that nobody counts, which is the reason this page ends in restraint rather than in spending. A customer stepping in off a Viman Nagar street receives the biggest single change of environment that anybody in your building will experience all day, and that step does its work regardless of your setting. The threshold is not the place where you need a strong level; it is the place where the contrast is free. What you need is for the room behind it to be quiet, consistent and unobtrusive - and consistency, not strength, is the thing a customer recognises the second time.
Count your door, do the arithmetic, and find the part of the shop you cannot hold
Three things decide how a street-facing shop holds a level, and the size of the machine is not one of them. The first is the aperture: how often the door cycles, how wide it is, how long it stays open, and how different the inside is from the outside. The second is depth: how much connected volume sits behind the entrance, and whether anything - an inner lobby, a turn, a change of level, a doored room - separates the front from the back. The third is dwell: how long a customer is actually in the room, which in this kind of retail is short, and which decides who you should be calibrating for.
What does not decide it is your machine's rating. Do the arithmetic once and that becomes obvious. A shop of 800 sq ft at a 10 ft ceiling is 8,000 cubic feet, which is 8,000 divided by 35.3, about 227 cubic metres. A larger unit at 1,500 sq ft and a 12 ft ceiling is 18,000 cubic feet, about 510 cubic metres. A small one at 500 sq ft and 10 ft is 5,000 cubic feet, about 142 cubic metres. Set those against a SOSA Vaayu at ₹11,999, published for approximately 1000 cubic metres of connected air, and the recurring finding of this bank falls out again: for a single retail unit the machine is not the constraint. Placement and setting are.
So the question is not "how much", it is "where, and over what gradient". And the gradient is measurable rather than mystical. That entrance zone - 12 ft of shopfront width by 8 ft of depth at a 10 ft ceiling - is 960 cubic feet, about 27 cubic metres. Against 227 it is roughly one eighth of your shop; against 510 it is about one twentieth. The deeper your unit, the smaller the fraction of it the door owns. That single ratio explains why two shops on the same road, with the same machine and the same setting, report completely different results, and why the one with a shallow frontage is the one that keeps buying upgrades.
And both Pune seasons act directly on that aperture, which is why the same shop needs two written settings. Through the dry heat of mid-March to mid-June, peaking in April and May with average highs around 37 to 38 degrees C, the difference between your conditioned interior and the street is at its largest, so each cycle swaps more vigorously - and the air conditioning is working hard, turning the room's air over faster. That is the honest explanation for a setting that seems to have vanished by three in the afternoon, and the genuinely counter-intuitive part is that those hottest months are also Pune's driest, with the humidity trough falling in February to April. Through the monsoon, roughly June to October with July the wettest month and indoor humidity peaking in July and August, monsoon days are mild rather than hot, so the difference across the door is much smaller and the exchange gentler - but what comes through is wet, on soles and hems and umbrellas, and the entrance becomes a water problem before it is a fragrance one.
The consequence is not qualitative at all. Each cycle is an exchange rather than a leak. Repeat it every ninety seconds for ten hours and the front of your shop is being continuously re-supplied with outside air. Functionally, you have a ventilation system that nobody specified, nobody commissioned and nobody is maintaining, and its duty cycle is set by your trade. Look at it that way and the complaint dissolves: you are not losing fragrance, you are ventilating a zone, and the zone is exactly the one you happen to stand in.
Now the error this produces, which is the expensive one. The natural response to "I cannot smell it at the door" is to increase the output, and it cannot work, for a reason worth stating precisely: an ambient machine raises the level of a whole connected volume; it does not project a barrier at one point in it. So turning it up does not hold the threshold. It lifts the level everywhere behind the threshold - the middle of the floor, the counter, the back of the shop - while the doorway carries on reading of street, because the doorway's level is set by the door. You end up with an over-scented interior, an unchanged entrance, and a bill.
Two further arguments against going up, both specific to a high-cycle unit. The first is the person at the desk. They stand in the entrance airstream through every cycle of the day, swinging between conditioned air and street air, and they are simultaneously the most exposed person in the building and the cap on your setting. Whatever you choose has to be liveable for ten hours by somebody who cannot step away from the door. The second is the contrast, and it is the reason restraint is not a compromise here. A customer stepping in off the street already receives the biggest change of environment anybody in the building will get all day, and that step does its work without help. Spending output to impress somebody during four seconds at the threshold, at the cost of the room where they spend the other fourteen minutes, is the wrong trade.
And the line I will not cross. Never prop a door shut, never close a vent, never reduce ventilation or extraction, and never ask for a change to the building's or the mall's air handling so that a fragrance holds better - not in any phrasing, not for any register, not at any price. Those systems belong to your landlord, your mall management and the people responsible for the building, and they exist for reasons that have nothing to do with me. A well-ventilated shop with a busy door is genuinely harder to scent. That is a trade-off to describe honestly, not a problem to solve at the expense of your air.
So count your door. One busy hour, one quiet hour, every opening including staff and deliveries. Knowing that number rather than guessing it is the difference between a setting and a hope, and it is the only piece of data on this page that nobody but you can supply.
Total connected volume first. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A shop of 800 sq ft at a 10 ft ceiling is 8,000 cubic feet, about 227 cubic metres. At 1,500 sq ft and a 12 ft ceiling it is 18,000 cubic feet, about 510 cubic metres. At 500 sq ft and 10 ft it is 5,000 cubic feet, about 142 cubic metres. State the height you used, because the height is doing more work than owners expect - the same 800 sq ft at an 8 ft ceiling is only 6,400 cubic feet, about 181 cubic metres, and a low ceiling removes volume fast.
Then the entrance zone. Measure the width of your shopfront and the depth at which you stop feeling the street - for most units that is somewhere between two and three metres in. A zone 12 ft wide and 8 ft deep is 96 sq ft, and at a 10 ft ceiling that is 960 cubic feet, which divided by 35.3 is about 27 cubic metres.
Now the ratio, which is the whole point. Twenty-seven cubic metres out of two hundred and twenty-seven is roughly one eighth of your shop. Out of five hundred and ten it is about one twentieth. Out of one hundred and forty-two it is nearly one fifth. Three shops on the same road, three completely different problems, and the only variable that changed was depth.
That ratio explains almost every disagreement I have about this. The owner of a deep unit says the machine works beautifully. The owner of a shallow one says it does nothing. Both are describing the same machine at the same setting, and both are right, because in one case the door owns five per cent of the air and in the other it owns twenty. Depth is a property of your lease, not of your equipment, and no upgrade converts a shallow shop into a deep one.
Then look for a break, because a break is worth more than any upgrade. Walk your unit and find the point where the street genuinely stops being part of the air. Sometimes it is a gradual fade. Sometimes there is a real discontinuity - an inner lobby, a turn, a short corridor, a change of level, a doored viewing or fitting room. Where such a break exists, a door that stays shut ends one connected body of air and begins another, and scent does not travel through it. If you have that, your scented volume is the part behind it, your arithmetic has just become much smaller and much more stable, and your setting can come down rather than up. If you do not, your unit is one connected volume with a hole in one end, and the level everywhere in it is partly the door's decision.
And then design the gradient deliberately. Write down three zones and what each one gets. The threshold, from the door to a couple of metres in, is the street's and gets nothing from a machine - what belongs there is housekeeping: a clear floor, somebody who looks up, and in a wet month matting long enough for three or four strides so a sole actually dries, with somewhere for umbrellas that drains outside the conditioned area. The middle is transitional, will read differently at four in the afternoon than at eleven in the morning, and should never be the thing you calibrate for. The deep zone is yours, holds a level reasonably well, and is where the written setting lives.
Accept the consequence, because it is the point of the page: a customer will notice a difference walking from the pavement to the back of your shop, and that difference is the effect. A gradient is not a failure of scenting. On a street-facing unit it is what scenting done correctly looks like.
So the honest calibration target is the middle of the room in an ordinary trading hour, judged by somebody who has been outside for ten minutes, with a level low enough that a staff member standing there all day never has to think about it. Not the threshold, which you cannot control. Not the peak, which is not representative. And never your own nose at four in the afternoon, which has been adapted since eleven.
Two written settings across the Pune year, because the door behaves differently in the two seasons. In the dry heat of mid-March to mid-June, peaking in April and May with average highs around 37 to 38 degrees C - and these hottest months are also Pune's driest, the humidity trough falling in February to April, which is the opposite of what almost everybody assumes - the difference between your conditioned interior and the street is at its largest, each cycle swaps harder, and the air conditioning is running flat out and turning the room's air over faster. The result is a setting that feels as though it has evaporated by three in the afternoon. Nothing is broken: the room is exchanging faster and your nose has adapted since morning.
In the monsoon, roughly June to October with July the wettest month and indoor humidity at its annual peak in July and August, monsoon days are mild rather than hot, so the difference across the door is much smaller and the exchange gentler. But what comes through the aperture is wet - soles, hems, umbrellas, bags - with every cycle, and in that season the entrance stops being a fragrance question and becomes a water question, which is answered in the order that never changes: source, then ventilation, then cleaning, then fragrance. Matting long enough for three or four strides rather than one token mat inside the door; an umbrella stand that drains, outside the conditioned area if the building allows it; a mid-day mop pass over the entrance zone rather than one clean at close; and an air conditioner whose filters, coil and condensate tray have been serviced as the ordinary items they are. A register laid over a damp entrance gives you damp and fragrance, and most people find that worse than the damp alone.
So what should the front of the shop be doing, if not holding a level? Everything that is not fragrance, and this is where the honest advice stops being about my products. The threshold's job is to be clean, clear, well lit, uncluttered and staffed by somebody who looks up. In a wet month it is to dry a sole and take an umbrella. What it is not is a place where a machine can produce a result, and a shop that spends its scenting budget there has spent it in the one location where the money cannot work.
One written setting for the dry months, one for the wet, the same register in both, changed on a date you choose and recorded with the date and the name of whoever changed it. The Bluetooth app and timer on a Vaayu at ₹11,999 is what makes that survive a busy week, because the unit then runs to your trading hours and holds the written number rather than being nudged by whoever is nearest to it at four o'clock.
- Count every door cycle for one busy hour and one quiet hour before changing anything.
- Work out total volume and entrance-zone volume, and see which fraction the door owns.
- Move the unit deep, out of the entrance airstream and out of the AC supply airstream.
- Write the level for the middle of the room, plus a second setting for the wet months.
Own the depth, design the gradient, and stop judging the machine from the doorway
Now the register, which matters less than placement and much less than the gradient you designed. There are seven registers in the water-based Hotel Collection, each one SOSA's own hotel-inspired interpretation, and SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand.
For a high-cycle street-facing unit the steer is about presence rather than weight. A room whose air is partly re-supplied every ninety seconds is a variable room, and a heavy, sweet or resinous register in a variable room does not read as luxurious - it reads as inconsistent, because it is loud when the door has been shut for five minutes and absent when it has not. A dry, structural register behaves far better across that swing, because there is less of it to notice going and coming.
Quiet Luxury is white tea, bergamot and cedar, hushed and polished, and it is my default for a street-facing retail floor: it carries a little presence across a room without becoming weight, and presence is exactly what a shop with a busy aperture can actually hold. Forest Suite is cedarwood, vetiver and green leaves, grounding, biophilic and the driest of the shortlist; it reads as part of the building rather than as somebody's decision, which is useful in a shop where the customer is only there for fifteen minutes and should not spend any of them thinking about the air. White Tea Serenity is white tea, aloe and cedar, clean and weightless and spa-like, and it is the right call where the interior is pale and bright and anything warmer would sit oddly against it.
The ones I would be careful with. Warm Welcome is citrus, floral and sandalwood, a genuine hotel-threshold register - and on a page about a threshold you cannot hold, that is an irony worth naming: it is built for an arrival, and an arrival is precisely the zone a street door takes away from you. Lobby Bar is citrus, pepper and amber, bold, playful and after-dark, and it is a register with a time of day attached, which fights a shop open from eleven in the morning. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush is the character that suffers most in a room whose level swings. Tea Garden is jasmine, green tea and white tea, serene and the least risky floral in the collection because the jasmine sits inside the tea rather than on top of it; it is a legitimate choice for a deep, quiet unit and a harder one for a shallow, busy one.
I will not rank those seven against each other on measured throw or longevity. SOSA does not publish that comparison, and the variables that dominate here - connected volume, ceiling height, how often your door cycles, where the unit sits and the level you write down - belong to your unit rather than to the blend.
And the zones that get nothing at any setting: the first couple of metres inside the door, the stockroom, the staff room and anywhere a customer does not go. Not a lower setting - nothing. Anyone on the desk can switch a named unit off without asking a manager, that day, without justifying it. A report of sensitivity from a staff member or a customer is a recalibration signal rather than a tolerance problem, and the person standing beside that door for ten hours is the most exposed person in the building and the cap on your level. I make no health or allergy claim in either direction.
| Scent | Why it suits the mood |
|---|---|
| Quiet Luxury · the deep floor, and the default | White tea, bergamot and cedar. Hushed, polished and unsweet - presence rather than weight, which is what a room re-supplied with outside air every ninety seconds can actually hold. Place it deep, out of both airstreams, and write the level for the middle of the floor. |
| Forest Suite · a timber, stone or plant-heavy interior | Cedarwood, vetiver and green leaves. The driest of the shortlist and the one that reads as structural rather than decorative, so a fifteen-minute customer receives it as part of the building rather than as a decision somebody made. It survives a swinging level better than anything sweeter. |
| White Tea Serenity · a pale, bright, minimal fit-out | White tea, aloe and cedar. Clean, weightless and spa-like, reading as clean rather than as scented. The lightest of the three, which suits a shallow unit where the level is variable and anything with weight would announce its own coming and going. |
| Nothing at all · the first two metres, and the stockroom | Not a lower setting - nothing. An entrance zone 12 ft wide by 8 ft deep at a 10 ft ceiling is about 27 cubic metres of air that the door re-supplies all day, and no machine holds it. What belongs there is a clear floor, good light, somebody who looks up, and in a wet month matting that actually dries a sole. |
So the buying answer, sized by the volume behind the entrance rather than by the frustration at it. If your unit has a genuine break - an inner lobby, a turn, a doored viewing or fitting room - and the volume behind it is a single enclosed space, an ultrasonic is often the whole purchase: the SOSA Boond at ₹899 for a small enclosed room, or the SOSA Sukoon at ₹1,899 for a larger one, both 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 lets you audition registers in your own air, and in a unit like yours judge on day five from the middle of the floor rather than on the first afternoon from the doorway.
Where the shop is one connected volume with a hole in one end of it - entrance, floor, counter and back all reading as one body of air - 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 through a Pune monsoon month is a plain design preference in a unit whose door admits wet air and wet footwear all day. That is a design preference, not a humidity, drying, dehumidifying or air-quality claim, because no SOSA product makes one. Bluetooth app and timer, which on a high-cycle unit is the operationally useful half: it runs to your trading hours, holds one written setting through the wet months and a different one through a dry April, and is not nudged at four o'clock by somebody whose nose adapted at eleven. Rated for approximately 1000 cubic metres of connected air, with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly; 400ml tank; freestanding or wall and HVAC mount; DC 12V / 1A at 5W, so it needs a live socket; CE, RoHS and SGS. Against a 227 cubic metre shop it is considerably more machine than the volume needs, which is why the instruction is to run it low and spend your attention on placement. Two systems, and they are not interchangeable: the ultrasonics are water-based, while the Vaayu and the ducted machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - run waterless nebulising oil. The ₹299 water-based bottle never goes into a Vaayu, and a scenting unit is never ducted into air handling that serves premises you do not control, which in a mall unit rules the ducted machines out entirely.
If what you want is no plug, no noise and nothing to switch off, the SOSA reed diffusers are their own registers rather than Hotel Collection ones: Mountain Breeze ₹849 is Himalayan pine, sage and cedar; Morning Freshness ₹749 is Malabar lemon, mint and eucalyptus; Garden Bloom ₹799, Evening Calm ₹799 and Fresh Brew ₹849 complete the set. 130ml from ₹1,249, refills ₹2,399 and ₹3,499, about 6 to 10 weeks. A reed is passive and local: it scents the few feet around it and cannot fill a shop, which on a street-facing unit is genuinely useful, because a reed placed deep produces a gradient by its nature rather than by your setting - and there is no dial for anybody to turn.
To go deeper on what this page only touches: if your instinct is that a busy door justifies a stronger setting, that argument is taken apart properly in whether a Viman Nagar jewellery store should use stronger fragrance because customers come in from outside. If your unit is a salon, the source problem sits on top of the aperture problem and is handled in managing fragrance in a high-footfall Viman Nagar salon across a busy weekend. And if what you are designing is an arrival rather than a shop floor, the short-stay version of that question is building a memorable arrival for short-stay guests in a Viman Nagar hotel near the airport.
What SOSA does not publish, and this page will therefore not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time. Those depend on run hours, connected volume, how often your door opens and the setting you choose, and they are yours rather than ours. Send your plan, your ceiling height and your door count to WhatsApp at +91 96192 18531. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition is a real SOSA service discussed there rather than priced on a page - though the cheaper honest answer comes first, which is that one of the seven registers held consistently already is a signature, because consistency makes a signature and uniqueness does not.
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.

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.
