One machine on one connected volume gives you one register, one setting and one result, and it stops dead at every closed door. That is not a failure of the machine - it is how air works, and a coverage rating on any diffuser assumes one connected body of air. A single SOSA Vaayu at ₹11,999 is rated for approximately 1000 cubic metres of connected air; a single SOSA Sukoon at ₹1,899 with the water-based Hotel Collection from ₹299 handles a normal reception. Either way, the rooms behind shut doors are getting nothing, and how you feel about that decides everything else.
Several small units, one per room reaches those rooms. It also gives you several settings that will drift apart, because each one is judged by a different person on a different day in a different-sized room, and it produces a seam wherever two scented rooms meet - a corridor where two levels or two registers arrive together and make a third smell that nobody chose. Six Sukoon units at ₹1,899 each is ₹11,394, plus six bottles of Hotel Collection at ₹299 is ₹1,794, which is ₹13,188 - more than the single Vaayu, for an outcome that is harder to keep consistent.
And then the third option, which is the one I recommend to nearly every foot clinic that asks me this: one machine in reception and deliberate zeroes everywhere else. Not zones. Not a smaller version of zones. One scented volume, and every other room written down as intentionally unscented. That needs no zoning architecture at all, it costs ₹2,198 for a Sukoon and a bottle, and in a clinical building it is not a compromise between the other two. It is a better answer than either.
What does zoning actually cost in a clinic? Six rooms with a Sukoon each is 6 x ₹1,899 = ₹11,394, plus six bottles at ₹299 = ₹1,794, so ₹13,188 - against ₹11,999 for one Vaayu covering one connected volume, or ₹2,198 for the single-reception answer. The money is not the argument against zoning, though. The argument is that six settings become six different settings within a few months, and that several of those rooms should not have been scented in the first place.
What is a seam, and why does it matter in a clinic? A seam is the place where two scented volumes meet - typically a corridor, a doorway or an open threshold - and where two levels or two registers arrive together and combine into something neither room intended. In a foot clinic the corridor is usually also the route to the treatment rooms, so a seam is not just an aesthetic problem: it is fragrance arriving at a door you deliberately kept neutral. One scented volume has no seams, which is the quiet structural reason the single-reception answer wins.
Still, the comparison is worth doing properly, because there are real buildings where zoning is the right call and you should be able to tell yours apart from those. Here is what each architecture actually gives you.
Architecture one: a single machine on a single connected volume. Its virtue is consistency. There is one register, one setting, one number written on one card, and one result that is the same on Monday morning as it is on Thursday afternoon. Its limit is absolute and physical: it stops at every closed door. A machine cannot push scent through a shut door and does not particularly want to push it against a pressure difference either. So the question "will one machine cover my centre" is really the question "how much of my centre is one connected body of air", and in a clinic with cabin doors that stay shut for privacy the answer is: reception, the waiting area, and the corridor they open onto. Nothing else. Cost: a Sukoon at ₹1,899 for a normal reception, or a Vaayu at ₹11,999 rated for approximately 1000 cubic metres of connected air if the front of house is genuinely large and open.
Architecture two: several small units, one per room. Its virtue is reach - it is the only way to put scent behind a closed door, because nothing else can. Its costs are three, and only the first is money. The money: six rooms at ₹1,899 is ₹11,394, plus six bottles of the water-based Hotel Collection at ₹299 is ₹1,794, so ₹13,188 all in, or ₹7,188 if you use six Boond units at ₹899 - that is ₹5,394 - plus ₹1,794 of fragrance for smaller rooms. The second cost is drift: six machines means six settings, and six settings are adjusted by different people at different times for different reasons, so within three months you do not have a scenting scheme, you have six independent decisions. The third cost is seams: wherever two scented volumes meet - at a doorway, in a corridor, at an open threshold - two levels or two registers arrive together and produce a third result nobody chose, and it is always strongest exactly where people walk.
Now apply the clinic filter, and watch architecture two lose its reason to exist. Which of your eight rooms are actually fragrance opportunities? Not the treatment cabins - small, closed, clinical, a patient with a bare foot in someone's hands, instruments and dressings open, and at 100 sq ft and a 9 ft ceiling that is 900 cubic feet or about 25 cubic metres, the volume that over-scents fastest in the building. Not the procedure or nail-surgery room. Not the gait and casting area, where footwear comes on and off repeatedly and the honest answer is airflow and footwear discipline. Not the sluice, the store or the staff room, which are extraction and laundry questions. Not the WC, which is an extraction problem first and a single reed second. That is seven rooms gone, and the eighth is reception.
So the third architecture, which is the one to build: one machine in reception, and deliberate zeroes everywhere else. No zoning, because there is nothing to zone. No seams, because there is only one scented volume. No drift, because there is only one setting. And the closed doors, which are architecture one's limitation, become the mechanism that makes the plan work - a door that stays shut ends one connected body of air and begins another, which is precisely what turns "scented reception, unscented clinical rooms" into something you can deliver rather than something you hope nobody tests. The cost is ₹1,899 for the machine and ₹299 for the fragrance, and the treating clinician's judgement about their own rooms overrides all of it. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Zoning is a real technique and it is right in real buildings. A hotel with a lobby, a lift lobby, a spa corridor and a restaurant genuinely has four spaces that all want scent and want it differently. A large retail floor with distinct departments is the same argument. Those are places where several people are meant to be experiencing several deliberately different atmospheres, and where nothing behind any of the doors is clinical.
A podiatry centre is not that building. It has one space that wants scent and seven that do not, and the ones that do not are not neutral by accident - they are neutral because a patient is barefoot in a small room with a clinician working at close range for half an hour, or because people are exerting themselves, or because instruments and dressings are open. Zoning a building like that means engineering a way to put fragrance into rooms whose whole specification is that they should not have any.
There is a second, less obvious reason the single-machine answer suits a clinic, and it is about failure. With one machine, if something is wrong, there is one thing to check and one person who owns it. With six, a complaint from a patient - "it was very strong in the corridor by room three" - is a diagnostic exercise across several units, and the usual outcome is that somebody turns everything down and nobody knows what anything is set to any more. Simplicity is not a lesser answer here. It is the reason the plan is still intact in a year.
And one thing that is never part of either architecture: do not close vents, reduce extraction or slow air exchange in any room to help a scheme reach further. A well-ventilated clinic is genuinely harder to scent and that is the correct trade. If a zoning plan only works with the air turned down, it is not a zoning plan, it is a reason to go back to one machine at the front.
Two architectures, both costed - and the third one a clinic usually wants
Three questions decide the architecture, and they should be asked in this order. First: how many of your rooms are genuinely one connected body of air, which is a question about doors rather than about walls. Second: how many of your rooms are actually fragrance opportunities once the clinical filter has been applied, which in a foot clinic is a much shorter list than the floor plan suggests. Third: who is going to own the settings, because an architecture is only as good as its worst-maintained unit.
Most people ask them in the reverse order, starting with machines and prices, and end up buying an architecture rather than choosing one. It is worth resisting that, because the two real architectures behave so differently over a year that the purchase price is close to the least important thing about them.
It is also worth being clear about what "large" means here, because a large podiatry centre is not large in the way commercial scenting usually uses the word. A 1,000 sq ft clinic at a 12 ft ceiling is 1,000 x 12 = 12,000 cubic feet, about 340 cubic metres. A 1,500 sq ft centre at 12 ft is 18,000 cubic feet, about 510 cubic metres. A 2,000 sq ft centre at 12 ft is 24,000 cubic feet, about 680 cubic metres; at 14 ft it is 28,000 cubic feet, about 793 cubic metres. Those are whole-building figures and they are not what any machine is being asked to fill, because the building is not one volume. Subdivide honestly and the reception is 250 sq ft at 10 ft - 2,500 cubic feet, about 71 cubic metres - or 300 sq ft at 10 ft, which is 3,000 cubic feet and about 85 cubic metres, or at most a 500 sq ft open front of house at 12 ft, which is 6,000 cubic feet and about 170 cubic metres. Assume 9 to 12 ft in the clinical part of a clinic rather than the 14 or 16 ft you would assume in a showroom, and say which you assumed, because the difference between 9 and 12 is a third of the air.
The last framing is the one clinicians find most useful. Zoning is fundamentally a way of saying "these spaces should feel different from each other". Ask yourself whether that is true of your building. In a foot clinic, the honest answer is usually that the front of house should feel like a considered, well-run reception and every clinical room should feel like nothing at all - and "nothing at all" is not a zone. It is the absence of one, and it is free.
The virtue is consistency, and consistency is what actually reads as premium. One register, one setting, one number written in pen on a card next to the machine. A patient who came in for an assessment in March and comes back for a review in July meets the same air, and that repetition is what turns a fragrance into a house character. It costs nothing to maintain and it is the single most valuable property of any scenting plan. With one machine you have one thing to judge, one thing to write down, one thing to check on a Monday morning and one person who owns it.
The limit is physical and absolute. A machine cannot push scent through a closed door. It does not want to push it against a pressure difference either, which is why a room that is slightly positively pressured relative to a corridor stays remarkably clean of anything happening in that corridor. So the coverage figure on any machine - including the Vaayu's approximately 1000 cubic metres of connected air, and SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly - describes air that is joined together, not floor area on a plan. Work out which of your rooms are actually joined. Usually it is reception, the waiting area and the corridor they open onto; sometimes a consultation room that opens directly off the waiting area and shares its air anyway; almost never anything with a door that stays shut.
Sizing it is arithmetic and takes ten seconds per room. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. A 250 sq ft reception at 10 ft is 2,500 cubic feet, about 71 cubic metres. A 300 sq ft one at 10 ft is 3,000 cubic feet, about 85 cubic metres. A genuinely open 500 sq ft front of house at 12 ft is 6,000 cubic feet, about 170 cubic metres. A very large open lounge front of house at 750 sq ft and 12 ft is 9,000 cubic feet, about 255 cubic metres. Compare those with the Vaayu's rating and the honest reading is that the Vaayu is generously specified for every one of them, which is a reason to choose it for the app, the timer and the waterless behaviour rather than for the coverage.
Cost, stated plainly. For a reception of 71 to 85 cubic metres: a SOSA Sukoon at ₹1,899 running the water-based Hotel Collection from ₹299, with 100ml refills at ₹999 - so ₹2,198 to start. For a small enclosed front desk of 150 sq ft at 10 ft, which is 1,500 cubic feet and about 42 cubic metres, a Boond at ₹899 plus ₹299 is ₹1,198. For a large open front of house that runs twelve hours, a Megh at ₹3,499 with its 6 litre tank, or the waterless Vaayu at ₹11,999 when the app, the timer and the absence of any water tank near a clinical area are the point.
So the honest summary of architecture one: it does one thing extremely well and it does not pretend to do the other thing at all. Whether that is a limitation depends entirely on whether you wanted the other thing - and in a foot clinic, you generally did not.
The money first, because it is the part people expect to be the argument and it is not. Six rooms with a Sukoon each: 6 x ₹1,899 = ₹11,394, plus six bottles of the water-based Hotel Collection at ₹299 = ₹1,794, so ₹13,188. Six smaller rooms with a Boond each: 6 x ₹899 = ₹5,394, plus ₹1,794 of fragrance = ₹7,188. Against one Vaayu at ₹11,999, or the single-reception answer at ₹2,198. So zoning with the larger ultrasonics costs a little more than one commercial machine and roughly six times the single-reception answer. That is real but it is not decisive, and I would not argue anyone out of zoning on price alone.
The first genuine cost is drift. Six machines means six settings, and settings do not stay where you put them in a building with staff. One gets nudged up on an afternoon when somebody's nose had adapted after four hours indoors. One gets turned down after a comment. One gets refilled with a different register because that was the bottle in the cupboard. One gets unplugged for a socket and comes back on a different setting. Within three or four months you do not have a scheme, you have six independent decisions made by six people on six days, and nobody can reconstruct what the original plan was because nobody wrote it down. That is not a criticism of anyone's staff. It is what happens to six dials in a working clinic.
The second genuine cost is seams. Two scented volumes that meet produce a third result at the join, and the join is always a place people walk through. A corridor between a scented reception and a scented consultation room receives both, in proportions that change with every door that opens, and the combination belongs to nobody. If the two rooms are running different registers it is worse, and a surprising number of zoned buildings end up running different registers by accident rather than by design, because of the refill point above. A patient walking from reception to a treatment room passes through the seam, and the seam is the strongest, least controlled fragrance experience in the building.
The third cost is specific to clinics and it is the serious one. Zoning puts machines close to rooms you deliberately kept neutral. A unit in the corridor outside cabin three is a unit whose output is tested against that cabin's door every time it opens, and cabin doors open constantly. A unit in a consultation room next to a treatment room shares a return grille with it more often than not. The whole reason the closed-door mechanism is valuable in a foot clinic is that it lets you promise an unscented clinical room and mean it, and every additional machine you place deeper into the building erodes that promise slightly. If you are going to zone, keep every unit in front of the clinical threshold, not behind it.
Where zoning is genuinely right: a centre with two physically separate front-of-house areas that do not share air - a ground-floor reception and a first-floor waiting area, say, or a foot clinic and a retail or orthotics showroom under the same roof with a door between them. Those are two receptions, not one reception zoned; each gets one machine, each gets its own written setting, and the register should be the same in both so that the building has one character rather than two. And the levels will be different numbers, because the volumes and the airflow are different - you match the perceived level, never the setting number.
The premise is simple: in a podiatry centre, the unscented rooms are not rooms you failed to reach. They are rooms you chose. A treatment cabin at 100 sq ft and a 9 ft ceiling is 900 cubic feet, about 25 cubic metres, with the door shut, a patient lying back with a bare foot in someone's hands, a clinician working at close range, and dressings and instruments open. A procedure or nail-surgery room is the same only more so. A gait and orthotics area has footwear coming on and off repeatedly. A rehabilitation gym has people exerting themselves, and the answer for that air is more of it rather than something added. The sluice, the store and the staff room are extraction and laundry questions. None of those is a fragrance opportunity, and calling them "unzoned" misdescribes a decision as an omission.
Once you see it that way the architecture designs itself. One machine, at the front, on the one connected volume where people arrive and wait. Every other room written on the plan as a deliberate zero, in those words, so that a new team member reads an empty cabin as a specification rather than as something to helpfully fix. No seams, because there is only one scented volume and its edges are doors. No drift, because there is one setting and one card. No machine anywhere behind the clinical threshold. And the closed doors - the limitation in architecture one - are doing the structural work for you, because a door that stays shut ends one connected body of air and begins another.
What it costs: ₹1,899 for a Sukoon plus ₹299 for the water-based Hotel Collection, so ₹2,198 for a reception of 71 to 85 cubic metres. ₹1,198 for a Boond and a bottle at a small enclosed desk of about 42 cubic metres. ₹11,999 for a Vaayu if the front of house is large and open, or if you want the Bluetooth app and timer so the scenting follows opening hours rather than running overnight into a closed building, or if you want waterless behaviour with no tank, no mist and no humidity anywhere near a clinical area. Or ₹749 for a reed diffuser at the desk if the front is small, quiet and you want no plug and nothing to switch off.
Then write it down, because a large centre has enough people in it that an unwritten plan is a memory rather than a plan. One page: the scented room, the register, the exact setting, the hours, where the machine lives, who is allowed to change it, and the rooms that are deliberately at zero listed by name. Add one line that matters more than the rest: any member of staff may switch the front-of-house unit off at any time without asking. If a patient at the desk says they are sensitive to fragrance, the receptionist should be able to turn it off there and then. That accommodation is a standing arrangement rather than a favour, it is better asked at booking than negotiated at the door, and a reported reaction is a recalibration signal rather than a tolerance problem. Your own staff, who are in that air eight to ten hours a day at closer range than any patient, are the most exposed people in the building and their comments outrank any measurement.
And the standing caveat that applies to every architecture on this page: fragrance adds scent and does not remove odour, so the order is always source, then ventilation, then cleaning and laundering, then fragrance. No SOSA product is a medical device, a clinical product or an air-treatment device, nothing here is clinical advice, and the treating clinician's judgement about their own rooms and their own patients overrides every recommendation on this page - including the recommendation to scent the front of house at all.
- Map which rooms share air and which have doors that stay shut during the day.
- Apply the clinic filter and strike out every room that should be at zero anyway.
- Price both architectures honestly - one machine against several plus fragrance.
- Then test the third option: one machine at the front, zeroes written down elsewhere.
One register held everywhere, or several registers that drift apart
Whichever architecture you end up with, one rule applies before any of the others: one register across the whole building. If you do zone, every zone runs the same blend. Different registers in different rooms is the single most common way a scented building starts smelling confused, because the seams between them carry both, and because a patient walking a corridor is assembling one impression of one practice rather than sampling a collection.
There are seven registers in the water-based Hotel Collection, each SOSA's own hotel-inspired interpretation - SOSA is independent and is not affiliated with, endorsed by or connected to any hotel brand. The clinic filter narrows them before taste gets a say: cool, dry and transparent, in that order, because a sweet or plush register in a clinical building reads as covering something rather than as generosity.
White Tea Serenity - white tea, aloe and cedar - is clean, weightless and spa-like, and it reads as clean rather than as scented, which is exactly the distinction a large centre wants at its threshold. Quiet Luxury - white tea, bergamot and cedar - is hushed and polished lobby calm, and it is the default if you want the decision made for you: unsweet, neutral across a wide patient list, and it carries a little presence at a doorway without becoming the thing anybody is thinking about. Forest Suite - cedarwood, vetiver and green leaves - is grounding and green and the right answer for a centre with timber, concrete, rubber flooring or a sports-medicine look; it reads as structural rather than decorative.
Tea Garden - jasmine, green tea and white tea - is a serene tea-and-jasmine calm with the jasmine sitting inside the tea, and it is the best floral option for a softer front of house, a step warmer than the white-tea pair and wanting a lower setting to match. Warm Welcome - citrus, floral and sandalwood - is warm, gracious hospitality and works in a family-practice front of house used with more restraint than a hotel would use it. Old-World Glamour - amber, violet and woods - is plush and evening-elegant and is the wrong register for a clinical building for the sweetness reason above. Lobby Bar - citrus, pepper and amber - is bold and after-dark and has essentially no home in a foot clinic.
What this page will not do, in a comparison page of all places, is rank those seven against each other on measured throw or longevity in order to tell you which one "covers more rooms". SOSA does not publish that comparison, nobody can produce one that survives contact with your particular building, and the variables that dominate - connected volume, ceiling height, ventilation rate, soft furnishing and the setting - are all yours rather than the blend's. Anybody telling you register A reaches further than register B in a corridor they have never stood in is guessing at your expense, and in an architecture decision that guess costs real money.
And the rooms that get no register in any architecture: the treatment cabins, the procedure and nail-surgery rooms, any cabin with a patient mid-treatment, the gait and casting area, a rehabilitation gym, the sluice and the instrument room. That list is the specification, not the part of the plan you negotiate down when a machine turns out to have spare capacity - and the treating clinician's judgement about their own rooms and their own patients overrides every word of it in either direction.
| Scent | Why it suits the mood |
|---|---|
| One machine, one volume · ₹1,899 to ₹11,999 | A Sukoon at ₹1,899 with fragrance from ₹299 for a reception of 71 to 85 cubic metres, or a Vaayu at ₹11,999 for a large open front of house of up to approximately 1000 cubic metres of connected air. One register, one setting, one result. It stops dead at every closed door, which in a clinic is the point rather than the problem. |
| Several units, one per room · about ₹13,188 | Six Sukoon units at ₹1,899 is ₹11,394 plus six bottles at ₹299 is ₹1,794. It is the only way to reach behind a closed door. It also gives you six settings that drift apart within months, a seam wherever two scented rooms meet, and machines sitting deeper into the building than a clinical plan really wants. |
| One machine and deliberate zeroes · ₹2,198 | The clinic answer. One machine at the front of house, every other room written down as an intentional zero. No zoning architecture, no seams, one setting, one owner. Costs a Sukoon at ₹1,899 plus a bottle at ₹299, or a reed from ₹749 at a small quiet desk. |
| Ducted into HVAC · ₹25,999 and up | Aangan at ₹25,999 covers approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 approximately 12,000 to 18,000 sq ft, both ducted. Wrong for a podiatry centre for a reason beyond size: a shared air handler carries fragrance into rooms you deliberately kept neutral, which is the opposite of what the plan is for. |
So the practical sequence, in the order you should actually do it. Walk the plan and mark which rooms share air with which - that is a doors question, not a walls question, and the honest test is whether the door is shut while a patient is in the room. Strike out every room that the clinic filter puts at zero. Measure whatever is left: area x height for cubic feet, divided by 35.3 for cubic metres. Then, and only then, look at machines.
For almost every centre, what is left is one reception between about 42 and 170 cubic metres, and the purchase is a SOSA Boond at ₹899 for a small enclosed desk, a SOSA Sukoon at ₹1,899 for a normal reception and waiting area, or a SOSA Megh at ₹3,499 with its 6 litre tank for a large front of house that runs twelve hours without anyone wanting to refill at lunchtime - all three running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999. The seven-bottle 15ml pack at ₹1,799 is how you test registers in your own air rather than from a description.
The SOSA Vaayu at ₹11,999 is the answer when the single connected volume is genuinely large, when the level has to be identical every day without anyone remembering, or when the Bluetooth app and timer matter - which in a clinic is the strongest argument of the three, because it means the front of house is right when the first patient arrives and the machine is not running at three in the morning into a closed building. Waterless cold-air nebulising of undiluted oil: no water, no humidity and no wet residue, which is why it belongs in a clinical building rather than a machine with a tank. Approximately 1000 cubic metres of connected air, 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. 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.
Two systems, and they are not interchangeable. The ultrasonics are water-based cool-mist machines; the Vaayu and the ducted Aangan at ₹25,999 and Meenar at ₹38,500 run waterless nebulising oil, and the ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. If you are choosing a register on an ultrasonic today and expect to move up later, say so on WhatsApp before you buy.
And if the front desk wants no plug, no noise and nothing to switch off, the SOSA reed diffusers are their own registers: 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; Mountain Breeze at ₹849 is Himalayan pine, sage and cedar; and Fresh Brew at ₹849 is Coorg coffee and Kerala vanilla, which is lovely at home and wrong at a clinical desk. The 130ml is from ₹1,249, with 300ml refills at ₹2,399 and 500ml at ₹3,499, and a reed lasts about 6 to 10 weeks.
To go further on the parts this page compresses: the full subtraction for a building of this size, gym included, is worked out in how a 2,000 sq ft foot, ankle and rehabilitation centre should approach ambient scenting. If a reed at your desk already reaches reception and nothing beyond it, that is architecture working correctly and it is explained in why you can smell your reed diffuser at reception but nowhere else. The airflow mechanisms that will decide where any of these architectures actually puts its fragrance are in how AC airflow affects fragrance distribution in a multi-room podiatry clinic, and the direct verdict on the commercial machine is when a podiatry clinic needs active waterless scenting like the SOSA Vaayu.
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 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.
