Placement in a clinic is an airflow question, and there are five rules that answer it. Put the machine in the volume you want scented, not in the corridor between volumes. Keep it out of the direct airstream of an air-conditioning supply grille, which will carry it away from where you wanted it. Keep it away from a return grille, which will pull it straight out of the room. Keep it away from the door to the treatment corridor, because that is how fragrance ends up in the rooms you decided should not have any. And put it where air moves gently - not in a blast, and not in a dead corner behind the desk where nothing moves at all.
Then two practicalities that are specific and easy to get wrong. The SOSA Vaayu at ₹11,999 is mains powered at DC 12V / 1A, 5W, so it needs a live socket - which means placement is partly an electrical question, and in a reception full of card machines and printers that is a real constraint. And it should sit out of the patient's direct sightline and out of reach, because a machine a patient can see is a machine a patient evaluates, and a machine a patient can reach is a machine that gets adjusted.
None of it changes the order that governs this whole bank. Fragrance adds scent and never removes odour, so footwear storage, ventilation, cleaning and laundering come before you decide where anything goes.
Why can we smell it at the desk but not in the waiting area? Almost always placement rather than capacity. Either the machine is in a dead corner where nothing moves, so the fragrance stays local, or it is in the airstream of a supply grille that is carrying it somewhere else, or a return grille between the two areas is removing it before it crosses the room. Before you buy a bigger machine, find your grilles, move the unit three metres and give it a week.
How do I stop the reception scent getting into treatment rooms? Move the machine away from the door to the clinical corridor, and check three specific paths: the undercut gap beneath that door, a shared return grille that connects the two volumes through the ceiling, and the corridor itself acting as a plenum when doors are propped open. A closed door ends one connected body of air and begins another, which is the mechanism that makes a scented reception with unscented clinical rooms real - but only if the source is not sitting next to that door.
First, find your grilles and mark them on a sketch. Every air-conditioned reception has at least one supply - the grille that blows - and usually a return, which is the grille that draws air back. Cassette units in the ceiling do both and the difference between the two is not obvious from the floor. The simplest test in the world settles it: hold a single tissue up under each grille. If it blows away from the grille, that is a supply. If it clings to the grille, that is a return. Do it at every grille in the front of house and write S or R on your sketch. Almost no clinic owner has ever done this, and it takes four minutes.
Second, find where the air actually moves. Walk the reception slowly with the tissue held loose at chest height and watch what it does. You will find three kinds of place: the blast, directly under or in front of a supply, where the tissue is pushed hard; the drift, most of the room, where it moves gently; and the dead spot, typically a corner behind a counter or under a fixed bench, where it does nothing at all. Mark all three.
Third, mark the doors. The street door, and - critically - the door to the treatment corridor. Note whether each is normally open, normally shut, or propped. A door that stays shut ends one connected body of air and begins another; a door that is propped open for convenience joins two volumes you thought were separate, and in a clinic that is nearly always the reason fragrance is reaching a room it should not.
Fourth, mark the sockets. This is not an afterthought. The Vaayu is mains powered at DC 12V / 1A, 5W, so it goes where there is a live socket, and in a clinic reception the sockets are already busy and the floor is walked over by people with foot complaints, often with a stick or a frame. A cable across a walkway is not an inconvenience in this building; it is a hazard, and it disqualifies an otherwise good position outright.
Now place it. The right spot is in the drift zone, inside the volume you want scented, at roughly chest to head height, several metres from the return grille, not in the blast from the supply, not within a couple of metres of the treatment corridor door, not in the dead corner, not in the patient's direct sightline, not within reach of a waiting chair, and next to a socket that does not need a cable run. In most clinic receptions there are exactly one or two positions that satisfy all of that, which is a relief - it means the decision makes itself once the map exists.
Then leave it there for a fortnight before you judge anything, and judge it by walking in from outside rather than by standing next to it. If the far chair still gets nothing after two weeks in a good position, then you have a capacity question rather than a placement one, and that is the point at which a larger machine is the honest answer. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The single most useful sentence on this page is the one about the corridor. In a great many clinics the machine ends up in the corridor - because that is where the spare socket is, because it seems central, because it is out of the way. A corridor is the worst position available in a clinic. It is a fifteen-second room that nobody occupies, it is connected to everything, and it sits directly outside the doors you have decided to leave unscented. Scenting the corridor means dosing the space nobody is in, while reception gets a leak of it and every treatment room door gets tested every time somebody walks through. If your machine is in a corridor today, moving it into the reception is likely to be the single biggest improvement available to you, and it costs nothing.
The second most useful is about the return grille, because it is invisible and it explains a complaint that sounds like a capacity problem. A return is a hole in the room that removes air continuously. Put a diffuser near it and you are paying to scent the inside of your ductwork. The room reads as weak, the owner turns the machine up, the ductwork gets more, and the room reads as weak at a higher setting. That loop is genuinely common and it is entirely solved by moving the unit.
Third, the height. A machine on the floor in a clinic reception is in the worst air in the room and in the worst place for a building where people walk with sticks and frames and where shoes come off. Chest to head height puts the output into the part of the room people actually occupy, keeps it out of the way of feet and cleaning, and keeps the cable off the ground. The Vaayu mounts freestanding, on a wall or into HVAC, and in a reception a wall mount at height is usually the tidiest of the three.
And a placement point that is about people rather than air: out of the patient's direct sightline. A visible machine is a machine that gets looked at, and a machine that gets looked at converts an ambient impression into a product somebody is evaluating - which in a clinical space is exactly the shift you spent the money to avoid. Behind or beside the seating, on a wall above eye level, or tucked to one side of the desk are all better than centre stage on the counter.
The airflow map, and the four places a machine must not go
Placement is the cheapest lever in commercial scenting and the one owners spend the least time on. The dial gets weeks of attention; the position gets whatever the socket allows. That is backwards, because in a small room - and a clinic reception is a small room, commonly 42 to 102 cubic metres - position changes the perceived result more than a notch on the setting does.
Three things decide the position, and they are worth separating because they pull in different directions and you have to reconcile them.
The first is volume boundaries: the machine belongs inside the body of air you intend to scent, and every coverage rating anybody publishes, SOSA's included, assumes one connected volume. In a clinic that boundary is created by doors, and it is the mechanism that makes a scented reception with unscented clinical rooms achievable. Placing the source on the wrong side of a boundary, or worse, in the passage between two boundaries, defeats the whole arrangement.
The second is air movement, which is the part almost nobody maps. Fragrance released into still air stays near where it was released; fragrance released into a strong airstream goes wherever that stream goes, which is frequently not where you wanted it and sometimes straight into a return duct. The target is neither: gentle, general movement, which is what most of a reception has once you have identified and avoided the two extremes.
The third is the human layer: sightline, reach, safety, and the electrical reality that a mains-powered machine has to live near a live socket. In a foot clinic the safety part is not boilerplate - your patients are, by definition, people with foot and ankle problems, some of them using a stick, a frame or a moon boot, and a trailing cable in that room is a genuinely poor idea rather than an untidy one.
Underneath all three sits the order this bank never departs from. Fragrance adds scent and never removes odour. If the reception smells of shoes parked under a chair since two o'clock or of the housekeeping round, no position is the right position, because you are placing a source that will combine with something rather than replace it. Source, then ventilation, then cleaning and laundering, then fragrance - and only then, where to put it.
A coverage rating assumes one connected body of air. A machine cannot push scent through a closed door, and it does not especially want to push it against a pressure difference either. So the first question is not "where in the room" but "which room", and in a clinic the answer is the reception and waiting area, because that is the volume you decided to scent and the clinical rooms are the volumes you decided to leave alone.
The corridor is the trap. It is where the machine ends up in a large proportion of the clinics I have seen, and the reasons are always sensible ones: there is a free socket, it seems central, it is out of the way of patients, and somebody thought a central position would distribute better. Every one of those reasons is wrong in a clinic. A corridor is a transit space that nobody occupies for more than fifteen seconds, so you are dosing air that nobody is sitting in. It is connected to everything, so the level you set for the corridor leaks into the reception at an uncontrolled fraction. And - the serious one - it runs directly past the doors of the rooms you have decided to leave unscented, which means every time one of those doors opens, the corridor's air goes in.
The corridor also does something structurally unhelpful that is worth naming, because owners meet the symptom without recognising the cause: it can behave as a plenum. If the reception is positively pressurised by a supply grille and the treatment rooms have doors with an undercut gap, the corridor becomes a reservoir that feeds those rooms continuously through the gap under each door. A door that is shut is a real boundary for bulk air movement, but a 12 to 20 mm undercut is a genuine path, and a source sitting in the corridor is a source sitting at the top of that path.
So: put it in the reception. Inside the volume, several metres from the treatment corridor door, ideally with the seating between the machine and that door rather than the machine between the seating and the door. If the reception is a long room with the desk at one end and the corridor at the other, the machine belongs at the desk end - which is also usually where the sockets are, so the two constraints agree for once.
Two related situations worth handling explicitly. If your reception opens into the corridor with no door at all, then the corridor is part of your connected volume whether you like it or not, and the honest response is to size and set for the larger volume and to accept that the clinical room doors are now the only boundary you have. That is a strong argument for keeping those doors shut as a matter of routine and for checking the undercut path. And if your clinic sits inside a larger multi-speciality building where you do not control the shared corridor, then your street door is your boundary, the machine goes well inside it, and nothing you do should be aimed at scenting a corridor that is not yours.
One more boundary that people forget: the WC. It is usually off the reception, it usually has extraction, and an extract fan is a hole that removes air from your connected volume continuously. Do not place the machine near that door either. Fix the WC with its own extraction and, if you want, its own quiet reed at ₹749 that is a lower version of the front register rather than a different character announcing itself down the corridor.
Find the grilles with a tissue. Hold a single sheet of tissue loosely under each grille in the front of house. Blown away means supply. Sucked against means return. Ceiling cassettes do both, with the supply usually round the outside and the return in the middle. Write S and R on a sketch of the room. This takes four minutes and it is the highest-value four minutes in this entire bank.
Do not put the machine in the direct airstream of a supply. This feels counter-intuitive - surely the blowing grille distributes it? - and it is wrong for two reasons. The stream is fast and directional, so it will carry the fragrance to wherever that stream terminates, which is typically the opposite wall or the far corner rather than evenly through the room. And the stream is where the concentration is highest, so anybody sitting in its path gets a much stronger dose than the room average. The symptom is a reception that reads as uneven and slightly too much in one chair, and the owner's instinct is to turn it down, at which point the rest of the room gets nothing.
Do not put the machine near a return grille. A return is a continuous extraction point. Anything released within a metre or two of it is removed from the room before it has diffused. This is the loop that produces the classic complaint: the room reads as weak, so the setting goes up, so more goes into the ductwork, so the room still reads as weak at a higher setting - and if the return is shared with other parts of the building, the fragrance is now appearing somewhere you did not choose, which in a clinic can mean a treatment room. If reception smells right at the desk and the waiting corner smells of nothing, look for a return grille between the two before you look at a bigger machine.
Do not put the machine in a dead corner. The corner behind the reception counter, the space under a fixed bench, the alcove beside a cupboard: these are the places where the tissue does not move at all. A source there produces a strong local pocket and nothing beyond it, because there is no air movement to carry it. Owners then describe it as "you can only smell it right next to the machine", which is exactly correct and is a placement diagnosis rather than a product one.
Do put it where the tissue drifts. Gentle general movement is what distributes a fragrance evenly, and most of a reception has it. In practical terms that usually means: on a side wall a couple of metres from the supply rather than under it, at chest to head height, in the open part of the room rather than in a recess, with a clear path across the seating area.
Two clinic-specific airflow notes. A ceiling fan changes everything about this map and mostly for the better - a slow fan produces exactly the gentle general movement you want, and a source placed in a fan-stirred room distributes far more evenly than the same source in still air. If you have one, use it on a low speed and place the machine within its stirred zone but not directly under the blades. And an open window or a door propped for ventilation is a continuous outflow, which is fine and good and should never be closed to make fragrance last longer. If the room is genuinely well ventilated, that is an honest reason it is harder to scent, and the answer is placement and a machine sized for the volume, never less air.
Finally, the airstream question that matters most in this vertical: the path to the clinical rooms. Once you have the map, look at whether any supply grille blows from the reception toward the treatment corridor door, and whether any return in the clinical area could be drawing from the front. Those two paths are how a carefully unscented treatment room ends up smelling of the reception, and they are fixed by moving the source and by keeping the doors shut rather than by turning anything down.
The socket. The SOSA Vaayu runs on DC 12V / 1A, 5W and is mains powered, so it needs a live socket - it is not a battery product and there is no version of it that sits anywhere you like. The SOSA ultrasonics - Boond at ₹899, Sukoon at ₹1,899 and Megh at ₹3,499 - are mains devices too. So placement in a clinic is partly an electrical question, and clinic receptions are electrically crowded: a computer, a printer, a card machine, a router, a phone charger and usually a lamp are already competing for two sockets behind the desk. Work out where power actually exists before you fall in love with a position, and if the ideal airflow position has no socket, the honest options are to have one added properly during a quiet week or to choose a reed diffuser from ₹749 instead, which has no plug at all and can therefore sit exactly where the air is right. That is a real reason clinics choose reeds and it has nothing to do with budget.
No cable across a walkway, ever. This is the rule I would enforce most strictly in this particular vertical, and it should not need arguing. Your patients are people with foot and ankle problems. Some arrive with a stick, a frame, a moon boot or a post-operative shoe, and some are walking differently from how they normally walk. A cable taped across a reception floor is a poor idea in an office and a genuinely bad one here. If the position requires a cable run across a walkway, the position is disqualified. Along a skirting on the same wall is fine; across the room is not.
Height. Floor level is the worst air in the room, the worst place for cleaning around, and the place where a machine is most likely to be knocked, kicked or have a bag put on it. Chest to head height puts the output into the layer people actually occupy and keeps the unit out of the way. The Vaayu mounts freestanding, on a wall or into HVAC, and in a clinic reception a discreet wall mount at height is usually the tidiest of the three: nothing on the counter, no cable on the floor, nothing for a patient to move.
Out of the sightline. A machine placed in the middle of the counter is a machine that will be looked at, asked about and evaluated, and the moment a patient is evaluating your diffuser, the ambient effect you paid for has turned into a product in the room. That is precisely the conversion this bank spends its time trying to prevent, because in a clinical space a visible, nameable fragrance source invites the question of what it is there for. Behind the seating, high on a side wall, or tucked to one side of the desk are all better than centre stage.
Out of reach. A machine within reach of a waiting chair will eventually be touched: by a curious child, by somebody who thinks it is a humidifier, by a patient who genuinely does not want it running. The last of those is a legitimate request badly served by a machine on a counter, and the correct answer is not to make the machine harder to reach but to make "off" a state anybody on your team can set for a named room without a discussion, asked at booking rather than negotiated at the door. Out of reach is about accidents, not about preventing patients from having a say.
And not right beside a seated patient. Even at a low setting, somebody sitting a metre from the source for fifty minutes while the list runs late is having a completely different experience from somebody across the room. Since clinic dwell is unpredictable, and since you are always dosing the long tail, keep the source away from the chairs people actually sit in. Placement does as much work as the dial here, and it costs nothing.
- Sketch the front of house and mark every grille S or R using a loose tissue.
- Walk the room with the tissue and mark blast zones, drift zones and dead corners.
- Mark the doors, especially the treatment corridor door, and mark the live sockets.
- Place it in the drift zone, at head height, away from the corridor, with no cable run.
What placement does to the register, and what to run once the position is right
Placement changes how a register reads, which is worth understanding before you conclude you chose the wrong one. A source in a drift zone at head height delivers a diffuse, even, low presence, and every register in the collection behaves at its best that way. The same source in a blast zone delivers a directional, concentrated dose to whoever is downstream of it, and in that condition even the most transparent register becomes identifiable, because concentration is what makes anything nameable. So if the room reads as too characterful, move it before you change it.
The water-based Hotel Collection has seven registers, each SOSA's own hotel-inspired interpretation; SOSA is independent and is not affiliated with, endorsed by or connected to any hotel brand.
White Tea Serenity - white tea, aloe, cedar. Clean, weightless, spa-like, and the most transparent of the seven. It is the most forgiving of an imperfect position, because there is more distance between "not doing anything" and "somebody can name it", which gives you room to be slightly wrong about airflow while you learn the room.
Quiet Luxury - white tea, bergamot and cedar. Hushed, polished lobby calm, and the default if you have no strong view. It holds its shape at a genuinely low setting rather than collapsing into nothing, which matters when the machine has been placed properly and is therefore running lower than you expected to need.
Forest Suite - cedarwood, vetiver and green leaves. Grounding and green, the right answer for timber, concrete or a sports-medicine fit-out, and a register that is read as part of a building rather than as an addition to it - useful in a reception where the source is deliberately out of sight.
Tea Garden - jasmine, green tea and white tea. Serene tea-and-jasmine calm and the best floral option for a clinic, because the jasmine sits inside tea rather than on top of it. Florals become identifiable at a lower perceived level than teas and woods, so it is the register least tolerant of a bad position: in a blast zone it will name itself quickly. Place it well and run it low.
Warm Welcome - citrus, floral and sandalwood, warm and gracious, and a legitimate choice for a neighbourhood practice built on warmth. Use it with more restraint than a hotel would, and be careful with it in a small reception where the seating is close to any plausible source position.
Old-World Glamour - amber, violet and woods - and Lobby Bar - citrus, pepper and amber. Both excellent, neither belongs at a foot clinic front desk at any placement or level. Plush and bold are the two characters that read as covering something in a clinical space, and no amount of clever positioning changes that.
Those seven are water-based and 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, and the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine.
What this page will not do is rank the seven on measured throw or longevity, because SOSA does not publish that comparison and because this page has just spent two thousand words explaining why the room and the position dominate anything inherent to a blend. Anybody claiming register A carries further than register B in a reception they have never stood in, and whose grilles they have never found, is guessing at your expense.
| Scent | Why it suits the mood |
|---|---|
| The right position · drift zone, head height | Inside the reception volume, in the part of the room where a loose tissue drifts gently, at chest to head height, on a side wall or beside the desk, several metres from the treatment corridor door, out of the patient's sightline and reach, next to a live socket with no cable crossing a walkway. In most receptions there are only one or two positions that satisfy all of that. |
| In the corridor · the commonest mistake | A fifteen-second room nobody occupies, connected to everything, sitting outside the doors you decided to leave unscented. It can act as a plenum and feed the clinical rooms through door undercuts. If your machine is in a corridor today, moving it into the reception is probably the biggest free improvement available to you. |
| In the airstream · supply or return | Under a supply grille the fragrance is carried directionally to wherever that stream ends, and whoever sits in its path gets far more than the room average. Near a return grille it is removed before it diffuses, the room reads weak, the setting goes up, and you end up scenting the ductwork at a higher cost. Both read as capacity problems and neither is one. |
| In a dead corner · behind the desk | No air movement means no distribution: a strong local pocket by the machine and nothing at the far chair. The symptom is 'you can only smell it right next to it', which is an accurate description of the physics rather than a fault in the product. Move it into the drift zone before you consider anything larger. |
Placement also interacts with what you buy, so it is worth doing the arithmetic and the map together rather than in sequence. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A 150 sq ft reception at 10 ft is 150 x 10 = 1,500 cubic feet, and 1,500 / 35.3 is 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. A 500 sq ft open front of house at 12 ft is 6,000 cubic feet, about 170 cubic metres. Clinic ceilings are commonly 9 to 12 ft rather than the 14 or 16 of a showroom, so say which you assumed.
In a small enclosed reception of 42 to 71 cubic metres, an ultrasonic placed well is the whole purchase: the SOSA Boond at ₹899 for a small front desk area or the SOSA Sukoon at ₹1,899 for a normal reception and waiting area, running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999. The pack of seven 15ml bottles at ₹1,799 lets you try registers in your own air once the position is settled - and only once it is settled, because judging a register from a bad position wastes the test. If the waiting area runs from nine to eight without a break, the SOSA Megh at ₹3,499 and its 6 litre tank saves a refill at lunchtime. Note that all three are water-based cool-mist machines, which is one more placement consideration in a clinic: they add a little moisture locally, so they belong away from paperwork, away from equipment and away from anything clinical.
For a larger connected front of house, the SOSA Vaayu at ₹11,999 is the commercial machine and it is the easiest of the range to place well, because it does not use water at all. Waterless cold-air nebulising of undiluted oil means no water, no humidity and no wet residue anywhere, which is why it belongs in a clinical building rather than a machine with a tank. 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, takes a 400ml tank, and mounts freestanding, on a wall or into HVAC. The wall and HVAC mounting options are the placement features that matter here: a wall mount at head height solves sightline, reach, floor safety and cable routing in one decision, and an HVAC mount puts the source into the distribution system itself, which is the most even option available if your front of house is ducted and if the duct genuinely serves the front of house alone. It runs on DC 12V / 1A at 5W and is mains powered, so a live socket is required, and it carries CE, RoHS and SGS. Bluetooth app and timer mean the setting is a number rather than a nudged dial, and the machine runs only in opening hours. 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.
One important caution about HVAC mounting in a clinic, because it is the one placement decision that can undo your whole arrangement. Ducting a machine into a system that also serves the treatment corridor will deliver fragrance to the rooms you decided to leave unscented, and no door will save you, because the fragrance is arriving through the ceiling rather than through the doorway. Before anybody mounts anything into a duct, establish exactly which rooms that duct serves. If it serves the front of house only, an HVAC mount is excellent. If it is shared, do not use it - place a freestanding or wall-mounted unit in the reception instead. 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 for buildings where whole-system scenting is genuinely wanted, which a foot clinic almost never is.
And if the best airflow position in your reception simply has no socket, the honest answer may be a SOSA reed diffuser from ₹749, which has no plug, no noise and nothing to switch off, and which can therefore sit exactly where the air is right. Morning Freshness at ₹749 is Malabar lemon, mint and eucalyptus and Mountain Breeze at ₹849 is Himalayan pine, sage and cedar - the two that sit inside the clean-and-unsweet filter a clinic wants. Garden Bloom is ₹799, Evening Calm is ₹799 and Fresh Brew is ₹849, which is lovely in a home and wrong at a clinical 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. Placement rules still apply to a reed: drift zone, not the blast, not the dead corner, not beside a seated patient, and reachable so that it can be removed when a patient has asked for the room unscented.
To go further: whether your reception is small enough that a reed is the whole answer is worked through with the arithmetic in is a reed diffuser enough for a small foot-clinic reception. Once the position is right, the level method is in how strong fragrance should be in a podiatry waiting room. And the perception target that placement is ultimately serving - a room that is registered rather than noticed - is in should fragrance be noticeable immediately when patients enter a foot clinic.
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 floor plan and your grille positions 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 register held consistently already is a signature.
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.
- Not published, and therefore never stated on this page: consumption rate, refill frequency, monthly running cost, machine lifespan, installation lead time or any minimum order. Those go to WhatsApp +91 96192 18531.
Versailles
A 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.
