That is not a hedge or a conservative default. There are two hard reasons for it. The first is that people who are exerting themselves experience a given setting as considerably stronger than a seated person in the same building does, so a level that is right for somebody waiting is already too much for somebody walking a treadmill, and a "lower" setting in the assessment area is a guess at a number nobody can calibrate. The second is that ventilation must never be traded for fragrance in a room where people are working hard, and every conversation about holding a fragrance level in an active space eventually becomes a conversation about air movement. In an assessment area, air exchange is the requirement and fragrance is not a requirement at all.
Then there is the physical objection, which is the one that ends the discussion for most clinics: if the two spaces are open to each other, they are one volume and cannot hold two levels. There is no mechanism. You would get a gradient, strongest near the machine, weakest at the far end, and nobody planned where that gradient falls. And in that open case the assessment area's requirement sets the level for both spaces, which means the whole front of house runs lower than it otherwise would - or at zero, which is a perfectly good answer.
So this page is about how to build one level and one zero properly, how to tell whether you have one volume or two, and how to set the level that does exist. Nothing here is clinical advice, and the treating clinician's judgement about their own rooms and their own patients overrides every recommendation on it.
What if the assessment area is open to reception? Then it is not a second zone. Reception and an open assessment area are one volume - for example 250 sq ft at 10 ft plus 400 sq ft at 12 ft is 2,500 + 4,800 = 7,300 cubic feet, about 207 cubic metres - and one volume holds one level. In that case the more demanding space sets it, so the whole front of house runs lower than a closed reception would, and running nothing at all is a legitimate outcome rather than a failure.
How do I set the one level that does exist? Low, once, in writing, and then leave it alone for a fortnight. Judge it from the doorway on a morning the building has been shut rather than from behind the desk at seven in the evening, and set it for the person who has been waiting fifty minutes rather than the person walking through in thirty seconds. A SOSA Sukoon at ₹1,899 with the water-based Hotel Collection from ₹299 is usually the whole purchase.
You cannot specify it. How much lower? Half? A quarter? Lower than what, measured how? A room setting is not a unit of perceived intensity, and the relationship between a dial position and what a person notices depends on the volume, the ceiling height, the ventilation rate, how much soft furnishing is in the room and where the machine is standing. Two rooms with different dimensions running the same number on a dial are not running the same intensity, and two rooms running different numbers might be. So "lower" turns into a number somebody picked, and the number never gets checked because there is nothing to check it against.
You cannot deliver it if the rooms are joined. This is the part that ends the argument in most sports clinics, because most of them have an assessment area that is open to the front of house by design - that openness is half of why the place reads as a performance space rather than a corridor of doors. A machine cannot hold two levels in one body of air. Air moves, and what you get is a gradient: strongest within a couple of metres of the machine, weaker as you move away, and the shape of it decided by where the vents are and how often the front door opens. Nobody planned that gradient. In a sports clinic the strongest part of it is quite often exactly where somebody is being watched walking, because that is where the clear floor is and the clear floor is where a freestanding machine tends to end up.
And you cannot verify it, because the person checking is the person least able to. Whoever walks from reception into the assessment area to judge whether the level "drops enough" has been in the building for hours and has adapted to it. That adaptation is completely ordinary and it is the single biggest cause of over-scented commercial space in India. A two-zone plan is therefore a plan that will drift, and it drifts upwards, because the only feedback anybody ever acts on is somebody saying they cannot smell it.
Now the substantive reason, which stands even if you have a wall and a door between the two spaces and could technically run two levels.
A person walking or running is breathing considerably harder than a person sitting in a waiting chair, which means far more of the room's air passes through them per minute. The same setting is therefore experienced as substantially stronger by the person on the treadmill than by the person on the chair. Anything you set for the seated case is already too much for the active case, and the honest version of "lower" is "none". This is a statement about exposure and perception rather than a health claim; no SOSA product makes any health, therapeutic, performance, recovery or mood claim, and none is a medical device or an air-treatment device.
And the standing rule that closes it. In a room where people are exerting themselves, air exchange is the requirement and it matters more rather than less. Never reduce ventilation, close a vent or turn down extraction so that fragrance holds better in an assessment area. If you find yourself weighing air movement against how well a scent carries in that room, the answer was zero all along. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The practical test is one question, and you can answer it in ten seconds standing in your own building: is there a door between them that stays shut? If yes, you have two volumes and two decisions, and the decisions are "one low level" and "zero". If no, you have one volume and one decision, and the decision is a lower level than you would otherwise run, or nothing.
That is genuinely all there is to the zoning question, and I would rather give you the sentence than a matrix. Everything else on this page is the reasoning underneath it and the method for setting the one level that exists.
The other thing worth saying plainly is that people arrive at the two-intensity idea from a good instinct. They have noticed, correctly, that the assessment area is a different kind of space with different needs, and they are trying to respect that. The instinct is right and the implementation is wrong. Respecting the difference means acknowledging that an active space does not want ambient fragrance, not that it wants a smaller amount of it. A quarter of the wrong thing is still the wrong thing, and it costs you a second machine, a second setting to maintain and a second thing for somebody to adjust.
Then a governance point that sounds trivial and is not. Write the zero down. A physical note next to the machine: the register, the level, and the assessment area listed at zero with the reason beside it. In a sports clinic with a treadmill, a plate and shift patterns across two busy blocks, an unwritten arrangement lasts about a year before somebody helpfully carries a diffuser into the assessment room because it seemed a bit bare in there.
And your own staff are the check on the level that does exist. Whoever works the desk is in that air for the whole day, at closer range to the machine than any patient, across both busy blocks. If they mention it, that is a recalibration signal rather than a tolerance problem, and the first move is down.
Why two intensities is not a thing you can actually build
There are three things tangled up inside this question, and separating them makes it easy.
The first is whether two intensities are physically possible, which depends entirely on whether there is a door. This is the connected-volume rule and it is the most useful physical fact in commercial scenting: a coverage rating assumes one connected body of air, a machine cannot push scent through a closed door, and a closed door therefore ends one volume and begins another. Two rooms with a shut door between them can genuinely hold two different states, including one at a level and one at zero. Two areas that are open to each other cannot, no matter what you buy.
The second is whether two intensities are desirable even where they are possible, and the answer is no, for the exertion reason. The people in the assessment area are moving, which changes their relationship to the air in the room in a way that no dial setting compensates for. The right level for an active space is not a small number. It is zero.
The third is what happens to the level in reception once you accept that, and this is where sports clinics differ from ordinary ones. In a general foot clinic, reception is a fairly self-contained room and you set it for the waiting patient. In a sports clinic, the front of house is often deliberately open to the assessment area, because open sightlines to equipment are half of what makes the place read as a performance space rather than a medical one. That design choice, which is a good one, has a scenting consequence: your reception is not a room, it is one end of a larger volume, and the level has to be right for the whole of it. Since the far end contains people who are walking or running, the level for the whole thing comes down.
It is worth doing that arithmetic, because it changes what you buy as well as what you set. Floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres. A closed reception of 250 sq ft at 10 ft is 250 x 10 = 2,500 cubic feet, and 2,500 / 35.3 is about 71 cubic metres. An assessment area of 400 sq ft at 12 ft is 4,800 cubic feet, about 136 cubic metres. If they are separated by a door you are scenting 71 cubic metres. If they are open to each other you are scenting 2,500 + 4,800 = 7,300 cubic feet, about 207 cubic metres, which is nearly three times as much air at a lower level. Those are different machines and different settings, and the only thing that decides which you have is a door.
One clarification before the detail, because people sometimes read this page as anti-fragrance. It is not. Reception in a sports foot clinic is a real opportunity and one low register there is worth having: it makes the arrival read as controlled, it gives the practice a consistent character between visits, and it agrees with the materials if you choose a dry, unsweet one. The argument here is only about where the level stops, and it stops at the edge of the active space.
Every coverage rating you will ever read, including SOSA's, assumes one connected body of air. The SOSA Vaayu at ₹11,999 is rated for approximately 1000 cubic metres of connected air, and the operative word is connected. A machine cannot push scent through a closed door and it does not particularly want to push it against a pressure difference either. So the map of your building for scenting purposes is not the floor plan. It is the floor plan with the shut doors drawn as walls.
Apply that to a sports foot clinic and three configurations turn up, and yours is one of them.
Configuration one: a door between reception and the assessment area, and it stays shut. You have two volumes. Reception at 250 sq ft and 10 ft is 2,500 cubic feet, about 71 cubic metres, and the assessment area at 400 sq ft and 12 ft is 4,800 cubic feet, about 136 cubic metres. You can genuinely run a level in one and zero in the other, and it will hold. This is the configuration where the plan on this page is easy, and it is worth knowing that a door which is shut most of the time but opened between patients still works well enough - each opening exchanges some air, which is a small leak rather than a joined volume.
Configuration two: a wide permanent opening, no door. One volume of about 207 cubic metres, one level, and the level is set by the requirement of the more demanding end. In practice that means noticeably lower than you would run a closed reception, and it means the machine goes at the reception end rather than in the middle, so that the gradient falls the way you would choose rather than the way the sockets dictate. Many clinics in this configuration end up deciding that the honest answer is no ambient fragrance at all in the front of house, and a reed diffuser on the counter as a very local, very small presence instead. That is a good outcome, not a defeat.
Configuration three: a door that exists but is propped open all day. This is the commonest real-world case and it is the worst of both worlds, because the plan says two volumes and the building behaves like one. Decide which it is and commit. Either the door closes and you get two volumes, or it does not and you set one lower level for the pair. What you must not do is set a reception level as though the door were closed while it is in fact open, because then the assessment area is being scented by accident at a level chosen for a different room.
There are three leaks worth knowing about even when the door is shut, because they explain almost every case of "the scent is getting into the assessment room". The door undercut: the gap under a door is a real airflow path, particularly if the two rooms are at different pressures. The shared return grille: if one air handling unit takes return air from both spaces, they are connected through the ductwork regardless of the wall. And the corridor acting as a plenum: air moving through a circulation space carries whatever is in it into whichever room is drawing.
All three are placement and airflow problems rather than machine problems. Move the machine away from the door, away from the return grille and away from the path towards the assessment area, put it at roughly seated head height rather than on the floor, and keep it out of the direct airstream of any supply vent. If it is still arriving where it should not, the answer is a lower setting, not a bigger machine and certainly not a closed vent.
Exertion changes the exposure. Somebody walking briskly or running on a treadmill is moving a great deal more air through themselves per minute than somebody sitting in a waiting chair. Whatever is in that room's air, they are getting more of it, and they are getting it while concentrating on moving normally for a clinician who is watching. The consequence is that the same setting is experienced as considerably stronger in the active space, and any attempt to compensate with a lower dial position is guesswork about a quantity nobody in the building can measure. That is a statement about exposure and perception. It is not a health, therapeutic or physiological claim, and no SOSA product makes one.
Air exchange is the requirement in that room, and it is not negotiable. An assessment area with a treadmill in it needs its air replaced, and every design decision in there should serve that. Ambient fragrance sits in direct tension with it, not because the fragrance is harmful but because the whole logic of holding a scent level is the logic of retaining air, and the whole logic of an active space is the logic of replacing it. When those two arguments meet, ventilation wins, every time, without exception, and in any phrasing. Never close a vent, reduce extraction or lower an air-change rate in an assessment area so that a fragrance carries better. If you have ever caught yourself thinking that the scent "disappears too fast in there", that is the room telling you it is doing its job.
The clinical work in that room deserves a plain environment. A gait assessment is somebody trying to walk the way they normally walk while a clinician watches and a camera records. It is an oddly self-conscious few minutes for most people. There is no argument for adding an ambient fragrance to it, and the clinician's judgement about the conditions in which they assess a patient governs entirely.
And there is a simple operational argument. Two levels means two machines, two settings, two things to refill, two things to check and two things for a helpful new colleague to adjust. One level and one zero means one machine, one written setting and one clear rule. In a clinic running two busy blocks a day across a small team, the simpler arrangement is the one that is still correct in a year.
What about the middle cases? A stretching mat in the corner of a reception, a bike a patient warms up on for two minutes, a short walkway used briefly during an appointment. Use the same test: is anybody in this space exerting themselves for a sustained period? A two-minute warm-up in a reception does not make the reception an active space and does not change the level. A ten-minute treadmill run does, and that room is at zero. If you genuinely cannot decide, choose zero, because the cost of being wrong in that direction is that a room is slightly plainer than it might have been, and the cost of being wrong in the other direction is that somebody is exercising in a fragrance they did not choose.
Finally, the accommodation point, which belongs here more than anywhere. Anybody who tells you they are sensitive to fragrance should be able to have the machine off for their appointment without a discussion, and "off" should be a state any member of the team can set. Ask at booking rather than at the door, so it is a standing arrangement rather than a favour. And treat a reported reaction as a recalibration signal for the whole setting rather than as one person's problem.
Size it by arithmetic rather than by feel. A closed reception of 150 sq ft at 10 ft is 1,500 cubic feet, about 42 cubic metres. A 250 sq ft reception and waiting area at 10 ft is 2,500 cubic feet, about 71 cubic metres. A 300 sq ft front of house at 12 ft is 3,600 cubic feet, about 102 cubic metres. An open reception plus assessment area at 250 sq ft and 10 ft plus 400 sq ft and 12 ft is 7,300 cubic feet, about 207 cubic metres. Clinics run 9 to 12 ft rather than the 14 or 16 of a showroom, and the difference between 9 and 12 is a third of the air, so say which you assumed. A 42 or 71 cubic metre reception is a Boond at ₹899 or a Sukoon at ₹1,899 with the water-based Hotel Collection from ₹299. A 207 cubic metre open front of house is where the waterless Vaayu at ₹11,999 makes sense, run low.
Set it for the long tail. Dwell in a sports foot clinic waiting area is unpredictable, because three things run late for different reasons: an assessment overruns, a physiotherapy session overruns, and the evening block stacks up. So set the level for the person who has been sitting there for fifty minutes rather than the one walking through in thirty seconds. If it is comfortable at minute fifty it will be quietly right at minute eight, and the reverse is not true.
Set it once and write it down. A piece of paper next to the machine with the register, the setting, the run hours and the zero list on it. One named person owns that paper. Nobody else touches the dial. This sounds bureaucratic for a ₹1,899 machine and it is the difference between a plan and a drift.
Judge it from outside. Walk in from the street on a morning the building has been shut and read the first breath from the doorway before you step in. That is the only honest reading you will get, because within a couple of minutes of being inside you have adapted and your nose has stopped reporting. Ask three people who have just arrived what they notice, before telling them a diffuser exists. If nobody mentions it and nobody is bothered, you are approximately right. If two of the three can name a product, come down a notch.
Do not raise it during the busy block. A sports clinic has an early block and an evening block, and both are when somebody is most tempted to turn it up because the room is busy. Fragrance adds scent and does not remove odour, so raising the level into a loaded hour produces a combination rather than a cleaner room, and it produces a curve. A rise and a fade is the signature people read as concealment, and a flat line is the one they read as the character of the building. Whatever the busy block needs, it is ventilation and a footwear routine, not a bigger dose.
Expect somebody to say it has faded, and do not believe them immediately. Almost every time, it has not faded; the nose of the person judging has adapted. The correct response is to ask somebody who has been out of the building for an hour. If three separate arrivals also report nothing at all, then you have a genuine level problem and you can move up one notch, once, and leave it for another fortnight.
And use the timer. A clinic that opens at half past six wants the front of house right when the first person arrives and wants nothing running at three in the morning into a closed building. That is what the Bluetooth app and timer on the Vaayu are for, and what a disciplined switch-off achieves on an ultrasonic. A machine running unattended overnight is the most common way a reception ends up over-scented by nine in the morning without anybody having touched the dial.
- Redraw the plan with every shut door as a wall - that gives you your real volumes.
- Put the active assessment area at zero and write the reason next to it.
- Work out reception's cubic metres by hand and size the machine to that alone.
- Set one low level for the fifty-minute wait, record it, and name one person who owns it.
One register, one level, one zero - and how to set the level that exists
Since there is one register rather than two, the choice is a single decision and it is worth making it well. All seven are in the water-based Hotel Collection, each SOSA's own hotel-inspired interpretation, and SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand.
For a sports foot clinic front of house the filter is the same one that governs the whole bank, with one addition. The general filter is cool, dry, unsweet, in that priority, because a sweet or plush register in a clinical space reads as covering something. The addition specific to this page is that the register has to be comfortable at a low level, because the level here is lower than it would be in a closed reception - either because the assessment area is joined to it, or simply because a sports clinic front of house tends to be more open than a general practice's. Some registers hold their character when you take them down and some become a vague sweetness. The dry woody and white-tea ones hold; the plush ones do not.
Forest Suite - cedarwood, vetiver, green leaves, grounding and biophilic green - is the first answer here for exactly that reason. It is structural rather than decorative, so at a low setting it still reads as something rather than as a trace of something, and it agrees with the hard materials a sports clinic is made of. If your front of house is open to a walkway or a treadmill area, this is the register I would run.
White Tea Serenity - white tea, aloe, cedar, clean and weightless and spa-like - is the second, and the right one for a pale, bright, minimal reception. It is the most transparent register in the collection, which means it is very hard to over-notice, and that is exactly the property you want when the level has to be set for the whole of a joined volume.
Quiet Luxury - white tea, bergamot, cedar, hushed and polished - is the third and the safe default if you have no strong view. Unsweet, neutral across a mixed list, and it carries a little presence at a threshold without becoming the thing anybody is thinking about while they wait.
Tea Garden - jasmine, green tea, white tea - is the best floral in the collection and a fair choice for a softer front of house, though it is a step warmer than the white-tea pair and wants a lower setting again, which in an already low-level room starts to be self-defeating. Warm Welcome - citrus, floral, sandalwood - is a genuine threshold register for a warm neighbourhood practice and the wrong temperature for a sports fit-out. Old-World Glamour - amber, violet, woods - is plush, and plush is the character that reads as covering in a clinical building. Lobby Bar - citrus, pepper, amber - is bold and after-dark and has no home in a foot clinic at all.
Those seven are the water-based Hotel Collection and they run in the SOSA ultrasonics. The Vaayu and the ducted machines run four hotel-inspired waterless blends instead, supplied as one of three bundle choices with the machine, and the two are different fragrance systems: the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. If you expect to move up later, mention it on WhatsApp before you buy.
What I will not do is rank the seven on measured throw or longevity, and in this question that refusal matters more than usual, because the temptation is to reach for a "weaker" register instead of a lower setting. There is no such thing as choosing a register to solve a level problem. SOSA does not publish comparative throw figures, they would not survive contact with your room if it did, and the variables that dominate - connected volume, ceiling height, ventilation rate, soft furnishing, placement and setting - are all yours rather than the blend's. If the assessment area is getting fragrance you did not intend, the fix is the door, the placement or the level. It is never a different bottle.
| Scent | Why it suits the mood |
|---|---|
| Reception, with a door · one low level | 250 sq ft at 10 ft is 2,500 cubic feet, about 71 cubic metres, and it is its own volume if the door to the assessment area stays shut. One register, one written setting, set for the patient whose appointment has slipped by fifty minutes rather than for the thirty-second walk-through. A Sukoon at ₹1,899 with fragrance from ₹299 is usually the whole purchase. |
| Active assessment area · zero, with the reason written down | 400 sq ft at 12 ft is 4,800 cubic feet, about 136 cubic metres, and every one of them stays at zero. People walk and run in it, so they experience any setting as considerably stronger than a seated person does, and the requirement in that room is air exchange, which is never traded for fragrance. Write the zero on the plan next to the register and the setting. |
| Both, open to each other · one volume, one lower level | 2,500 + 4,800 = 7,300 cubic feet, about 207 cubic metres, and no mechanism exists to hold two levels inside it. The more demanding end sets the level, so the whole front of house runs lower than a closed reception would, the machine goes at the reception end so the gradient falls where you chose, and no ambient fragrance at all is a legitimate answer. |
| A propped-open door · decide, then commit | The commonest real configuration and the worst, because the plan says two volumes and the building behaves as one. Either the door closes and you get a level and a zero, or it stays open and you set one lower level for the pair. What you cannot do is run a closed-reception level through an open doorway and call the assessment area unscented. |
The purchase follows directly from which configuration you are in, and it is a small purchase either way.
Closed reception, about 71 cubic metres. A SOSA Sukoon at ₹1,899 running the water-based Hotel Collection from ₹299, with 100ml refills at ₹999. A smaller 42 cubic metre desk area is a SOSA Boond at ₹899. The pack of seven 15ml bottles at ₹1,799 is how you try registers in your own air rather than choosing from a description - one a week, at a low setting, judged on day five. If the clinic runs a long day across two busy blocks, the SOSA Megh at ₹3,499 with its 6 litre tank means nobody is refilling anything between them.
Open front of house, about 207 cubic metres. This is where the waterless SOSA Vaayu at ₹11,999 earns its place, run low. It is 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, so 207 sits comfortably inside it at a modest setting - which is exactly what you want, because a machine working gently in a large volume is easier to hold steady than a small one working hard. Its properties matter in this building: waterless cold-air nebulising of undiluted oil means no water, no humidity and no wet residue near a treadmill, a plate or a camera rig; the Bluetooth app and timer mean it runs your opening hours and nothing else; the 400ml tank and freestanding, wall or HVAC mounting give you placement choices; DC 12V / 1A at 5W means it needs a live socket; and it carries CE, RoHS and SGS. It is an ambient fragrance product rather than a clinical or air-treatment device, it adds scent rather than removing odour, and it cannot travel through a closed door - which on this page is the point rather than a limitation.
Two systems and they are not interchangeable: the ultrasonics are water-based cool-mist machines that put moisture into the air, and 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. Ducting deserves a warning on this page in particular: a ducted machine scents everything the system serves, and if one air handling unit serves both the reception and the assessment area then ducting hands you a single level across both, which is the arrangement this whole page argues against.
And the option that removes the dial entirely. A SOSA reed diffuser from ₹749 on the reception counter has no plug, no noise, nothing to switch off and nothing anybody can turn up during the evening block, which in a clinic with two busy blocks and a small team is a real advantage. Mountain Breeze at ₹849 is Himalayan pine, sage and cedar and is the closest to the dry woody direction this page recommends; Morning Freshness at ₹749 is Malabar lemon, mint and eucalyptus; Garden Bloom at ₹799 is British rose and night-blooming jasmine; Evening Calm at ₹799 is Kashmir lavender and chamomile; and Fresh Brew at ₹849 is Coorg coffee and Kerala vanilla, which belongs in a home rather than at a clinical front desk. The 130ml is from ₹1,249, refills are ₹2,399 for 300ml and ₹3,499 for 500ml, and a reed lasts about 6 to 10 weeks.
To go further: if your building also contains a physio gym and treatment cabins, the full arithmetic for all five volumes is worked by hand in how to scent a combined podiatry, sports physio and gait-analysis centre. If the clinic is large enough that you are weighing one signature against separate characters by zone, the strategy and the governance are in one signature scent or separate zones for a large sports foot and rehabilitation centre. And if the underlying question is really about the whole feel of a runner-focused practice rather than about levels, start with how a podiatry clinic serving runners should approach its interior ambience.
What SOSA does not publish, and what 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 and setting. That conversation happens with your plan in hand on WhatsApp at +91 96192 18531. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition made only for your practice 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 clinic is almost always the reception and waiting area alone - 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.

A foot clinic has a harder job than most places I write about, and it is worth saying plainly: your patients take their shoes and socks off, all day, in rooms that are often small and often air-conditioned with the windows shut. That is a real environment, and no bottle solves it. What solves it is where the shoes go, how the air moves, and what gets cleaned and laundered.
So the order matters more here than anywhere. Find the source. Move the air. Clean the surfaces and the soft things. Only then, in the reception where people wait, add one low register and hold it. Fragrance adds scent - it never subtracts one - and a scent laid over an odour makes a third smell that is usually worse than either.
The other thing I say to every clinician who asks me: the treatment rooms are not the opportunity. A patient lying back with a foot in someone's hands, a room with instruments and dressings in it, a person who has told you they react to fragrance - none of those want an ambient scent, and I would rather lose the second machine than pretend otherwise. Your clinical judgement about your own rooms outranks anything I have written here.
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 a medical device, a clinical product or an air-treatment device, and nothing in this guide is clinical advice - the treating clinician's judgement about their own rooms and patients overrides every recommendation here. 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.
