Fix the footwear question: where shoes go, and whether that place is away from the seating and away from the treatment couch. Get a real answer on whether your air conditioning brings in outside air or only recirculates, in writing, from the person who installed it or maintains it. Sort the upholstery and put the laundering on a written schedule with a named owner and a date. Get the AC filters and the drain tray onto the maintenance schedule and actually inspected. Deal with any damp as a repair rather than as a smell. And decide, on paper, which rooms in your clinic will be permanently unscented.
Then, and genuinely only then, work out the connected air volume of your front of house and buy the smallest thing that covers it.
Here is the part a fragrance house is not supposed to write. A clinic that does all of that very often needs much less fragrance than it budgeted for - a ₹749 reed diffuser on a desk instead of an ₹11,999 machine, or an ₹1,899 ultrasonic instead of a commercial unit, or in a fair number of cases nothing yet at all. That is a good outcome, not a lost sale. A clinic that buys a machine to cover an unresolved shoe rack ends up with a room that smells of both things, an owner who blames the fragrance, and a supplier who deserves the blame more.
Will fixing all that mean I need a smaller machine? Usually, yes, and that is the honest point of the list. A clinic with contained footwear, real air exchange, laundered fabrics and no damp often finds that a reed diffuser from ₹749 at the desk or a Sukoon at ₹1,899 with the water-based Hotel Collection from ₹299 is the entire requirement, rather than the Vaayu at ₹11,999 it had budgeted for. Sometimes the answer is nothing yet.
Which rooms should be permanently unscented? Treatment cabins, procedure and nail-surgery rooms, the casting and orthotics area, the sluice and instrument room, and any cabin with a patient mid-treatment. Write those on the plan before you buy anything, so it reads as a specification rather than as an omission somebody corrects in month seven. A closed door ends one connected body of air and begins another, which is what makes the arrangement real. The treating clinician's judgement about their own rooms overrides all of it.
One: the footwear question. This is the item that makes a foot clinic different from every other commercial space, so it goes first. Walk your own building at four in the afternoon and find out where shoes actually are - not where you intended them to be. In most clinics the honest answer is under a waiting chair, beside the treatment couch, or in a heap near the door, which means there is an open source at floor level, right next to seated people, for the length of every appointment and often longer. Give footwear a defined home: a rack, a cubby, a shelf or a tray, hard and wipeable and ventilated rather than fabric-lined, positioned away from the seating and away from the couch. Give patients somewhere to put a sock other than inside a warm shoe. Then live with the new arrangement for two weeks before you judge anything else, because it changes the baseline that every later decision is measured against.
Two: get a real answer about fresh air. Ask the contractor who installed your air conditioning, or who holds the maintenance contract, one question and get the answer in writing: does this system bring in outside air, or does it only recirculate? A wall-mounted split unit cools and stirs the air in one room and brings in nothing; it is not ventilation however hard it blows. A ducted system may have a genuine fresh-air intake or it may not, and you cannot tell by looking at a grille. This matters before a purchase because ventilation is the only step in the whole sequence that removes anything, and because a sealed recirculating clinic will make any fragrance you add behave differently - and, being honest in the other direction, a well-ventilated clinic is genuinely harder to scent. Either way you want to know which building you are in before you size a machine. What you must never do is reduce ventilation so the fragrance lasts longer.
Three: the upholstery and the laundering schedule. Soft material absorbs what is in the air and releases it back slowly over hours, which is why a clinic can be cleaned properly and still carry the day it has just had. Count what you actually have: eight chairs with 18 by 18 inch seats at 4 inches thick is 8 x 0.75 = 6 cubic feet of foam, plus about 4.5 cubic feet in the backs at 3 inches, so roughly 10.5 cubic feet of porous material sitting in your waiting room. Specify wipeable seating or removable washable covers with a spare set at the next replacement. Put cushion covers and throws on a weekly rotation, curtains on a fixed cycle rather than when visibly marked, and the entrance mat on a swap with a second mat rather than a clean in place. Write it down with a name and a date, because a schedule done on notice drifts longer every quarter.
Four: the AC filters and the drain tray. These are on almost every clinic's maintenance contract and inspected in almost none. Get them onto the schedule properly and get somebody to actually look, because a system that recirculates the same air all day is passing that air over the same components all day. This is ordinary plant maintenance rather than anything clinical or specialised, and it is the sort of thing that quietly determines how a building smells at four in the afternoon regardless of anything you buy.
Five: deal with damp. A wall, a leak, a mat that is wet at ten and still wet at closing, a bathroom with no working extraction, a monsoon month in a sealed building where nothing textile ever dries. Damp is a repair, and treating it as a smell is how it gets ignored for two years. Nothing you buy from a fragrance house touches it.
Six: decide which rooms are permanently unscented, and write it on the plan. Treatment cabins, procedure and nail-surgery rooms, the casting and orthotics area, the sluice and the instrument room, and any cabin with a patient mid-treatment. Make it a marked specification rather than an omission, so a helpful new team member does not add a plug-in in month seven. While you are there, set the standing arrangement for fragrance-sensitive patients: asked at booking rather than at the door, with "off" as a state anybody on the team can set for a named room without a discussion. And note the standing override - the treating clinician's judgement about their own rooms and patients beats every line of this page, including a decision to leave the front of house unscented too.
Only now do the arithmetic and buy. Front of house floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres; a closed door ends one connected volume and begins another. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Why bother with any of this if you are going to buy something anyway? Because the list changes what "enough" means. Fragrance adds and never subtracts, so whatever is still in the room when the machine arrives is still in the room afterwards, with a register on top of it. That is a third impression rather than a corrected one, and in a small warm clinic it is usually worse than either ingredient alone. Every item on the list reduces the first term in that sum, and the smaller the first term, the less you need of the second - which is the mechanical reason the budget comes down rather than a rhetorical one.
There is a second reason, which is diagnostic. If you install a machine into an unfixed building, you have changed two things at once and you will never know which one did what. When the room is still not right in week three, the available conclusions are "the fragrance is too weak" and "the fragrance is wrong", and both are wrong, and both lead to spending more. Fix the building first, live with it for a fortnight, and then add one thing. Now anything that changes is attributable.
A fair question is how long all this takes, and the honest answer is that most of it takes a fortnight and costs very little. A shoe unit and a second entrance mat are small purchases. A written laundering rota is an afternoon of thought. Getting a written answer from your AC contractor is an email. Damp is the only item that can turn into a real project, and if it does, that is information you needed before spending on anything else.
And one thing to say out loud, because clinic owners are usually too polite to ask it. If you complete this list and then tell a supplier what you have got, a decent supplier will sometimes tell you to buy less than you had planned, or to wait. If yours does not - if the recommendation is identical before and after a fortnight of source work - that tells you something useful about whose problem is being solved. This bank would rather sell a ₹749 reed into a clinic that needed a reed than an ₹11,999 machine into a clinic that needed a shoe rack.
The six things to fix, the two decisions to write down, and only then the arithmetic
The pre-purchase list exists because of one fact about the category and one fact about foot clinics.
The fact about the category is that fragrance adds and never subtracts. There is no mechanism by which an ambient fragrance product removes, neutralises, absorbs, deodorises, sanitises or purifies anything. So it is not a corrective tool. It cannot be aimed at a problem. It can only be laid on top of whatever the room already contains, which means the room's contents on the day of installation determine whether the purchase succeeds. That is why the shopping list comes last and the fixing list comes first, and it is not a matter of taste or of thoroughness. It is the arithmetic of the thing.
The fact about foot clinics is that the source is real, physical, renewed all day and entirely predictable. Patients take their shoes and socks off, in rooms that are small, often sealed and often air conditioned with the windows shut. A treatment cabin of 80 to 120 square feet at a 9 ft ceiling is 720 to 1,080 cubic feet, roughly 20 to 31 cubic metres. A 250 square foot reception at 10 ft is 2,500 cubic feet, about 71 cubic metres. These are small volumes doing a lot of work, and in small volumes everything - the source, the cleaning product, the recirculated air and anything you add - is concentrated.
Put those two facts together and the pre-purchase list stops looking like diligence and starts looking like self-interest. Every item on it reduces what the fragrance will be sitting on top of, which improves the result and reduces the size of the machine at the same time. There is no version of this where doing the list first makes the purchase worse.
The three factors below are the list in operational form. The first is the six fixes, with a rough sense of what each one costs and how long it takes. The second is the two decisions that have to be written down before anything is ordered, because they are the ones that get quietly reversed later if they only exist as an understanding. The third is the arithmetic and the physical installation questions - connected volume, sockets, placement, timer - which is the only part that involves a product at all, and which comes last for good reason.
One caveat that applies throughout. Nothing on this page is clinical advice, infection-control advice or a comment on any clinical standard; it is housekeeping, maintenance and specification for the way a building smells. Your own professional guidance, your practice policy and the treating clinician's judgement about their own rooms and patients govern everything beyond that and override every recommendation here.
Footwear. Effort: one small purchase and two weeks of habit. Walk the clinic at four in the afternoon and record where shoes actually are rather than where the plan says. Then give them a defined home away from the seating and away from the treatment couch: hard, wipeable and ventilated rather than a fabric-lined cubby or a cloth basket, which would simply relocate the reservoir to the point of highest loading. Give patients somewhere to put a sock that is not inside a warm shoe. This is the single highest-value item on the list in this vertical, because it is the one source that is renewed by every appointment, and it is the one no machine can help with.
Fresh air. Effort: one email, then a scheduling change. Ask your AC contractor or maintenance holder in writing whether the system brings in outside air or only recirculates. A split unit does not; a ducted system may or may not. Then set the routines regardless of the answer: front of house opened for ten minutes before opening so the day does not start on yesterday's air, treatment rooms aired between lists rather than at seven in the evening, WC and sluice extraction running as routine and checked occasionally to confirm it is actually moving air, and a purge before locking up. The one purchase that belongs here is an extract fan where there is none, and it will do more for a foot clinic than any fragrance product at any price. And the standing rule: never reduce ventilation, close a vent or turn off extraction so the fragrance lasts longer. A well-ventilated clinic is harder to scent, that is stated honestly here rather than hidden, and it is still the right trade.
Fabric. Effort: an afternoon of writing, then a recurring cost. Soft surfaces absorb and re-release slowly, which is why a cleaned clinic still carries its day. Specify wipeable seating or removable washable covers with a spare set whenever a chair is replaced. Then write the rotation down with a named owner and a date: cushion covers and throws weekly, cabin and privacy curtains on a fixed cycle rather than when visibly marked, entrance mat swapped with a second mat rather than cleaned in place, carpet and rugs deep cleaned at a stated interval, and the forgotten items - fabric-faced acoustic panels, pinboards, vertical blinds - on the list even if the cycle is long. The failure mode is never that laundering does not happen; it is that it happens on notice, so the interval drifts longer every quarter.
AC filters and the drain tray. Effort: a phone call and an inspection. Get them genuinely onto the maintenance schedule and get somebody to look rather than to sign. In a sealed clinic the same air passes over the same components all day, which makes plant maintenance a bigger contributor to how the building smells at four in the afternoon than most owners assume. This is ordinary equipment upkeep and nothing to do with fragrance, which is exactly why it belongs on the list before a fragrance purchase.
Damp. Effort: variable, and occasionally a real project. A wall, a leak, a chronically wet mat, a bathroom with no working extraction, a monsoon month in a sealed building where nothing textile dries. Damp is a repair. It also multiplies the fabric problem, because damp material holds more and releases more slowly, which is why a clinic that was fine in February can be noticeably worse in August with nothing else changed. If this item turns out to be big, that is information you needed before spending on anything else, not a reason to postpone it.
Two weeks after the last of those is in place, walk the building again at four or five in the afternoon on a full list, and bring somebody who has not been in it that day. Ask what they notice. If the answer is nothing in particular, the first project is done and the fragrance question can be asked properly for the first time.
Decision one: which rooms are permanently unscented. The default list is treatment cabins, procedure and nail-surgery rooms, the casting and orthotics area, the sluice and the instrument room, and any cabin with a patient mid-treatment. Mark them on the floor plan in the same way you mark the register - as a specification, not as a blank. The reason to write it rather than to say it is the month-seven problem: a well-meaning new team member finds a spare plug-in, notices cabin two has nothing, and helpfully corrects what they assume was an oversight. A marked plan makes that impossible without a conversation.
The physical fact that makes this arrangement real rather than aspirational is worth understanding, because it also affects where the machine goes. A door that stays shut ends one connected body of air and begins another. A coverage rating - including SOSA's - assumes one connected volume, and scent does not travel through a closed door, nor does it particularly want to travel against a pressure difference. So a scented reception with unscented clinical rooms is not a fudge or a hope; it is the ordinary behaviour of a building with doors. What does undo it is airflow rather than fragrance: a shared return grille, a generous door undercut, or a corridor acting as a plenum with the machine sitting in the airstream. If fragrance is reaching a room you meant to leave alone, look at those three before you look at the settings.
Decision two: the standing arrangement for fragrance-sensitive patients. Make it policy rather than a favour, and write it into your booking process rather than leaving it to the door. Ask at booking, which is both easier for the patient and far more useful for you. Make "off" a state that anybody on the team can set for a named room without a discussion, a justification or a manager. And treat any reported reaction as a recalibration signal rather than a tolerance problem - if it happens, the level comes down first and the conversation happens second.
That decision extends to your own staff, who are the most exposed people in the building by a large margin. A receptionist sits closest to the machine for eight to ten hours a day, six days a week; a patient gets forty minutes twice. Ask your team before you buy and again a fortnight after you install, and mean it. If any of them mentions the scent, come down. This is not politeness - it is the only reliable instrument you have, because everyone who works in the building adapts to it within minutes of arriving each morning, which means nobody inside can judge the level and the people most affected are the ones with the least ability to notice it.
And the standing override, written on the same sheet: the treating clinician's judgement about their own rooms and their own patients beats every recommendation on this page, in either direction. That includes a decision to leave the front of house unscented as well, which is a perfectly good answer and one a fair number of clinics arrive at after doing the six fixes. It also includes any relevant professional guidance, practice policy or - if you are inside a hospital or a multi-speciality building - a facilities or infection-control policy that is not yours to overrule. If you do not control the corridor or the air handling, you do not control the decision, and that is worth establishing before you spend rather than after.
Do the arithmetic by hand. Floor area multiplied by ceiling height gives cubic feet; cubic feet divided by 35.3 gives cubic metres. Measure only the volume you are actually scenting, which in a foot clinic is reception, waiting and the arrival corridor, and stop at any door that stays shut. A 150 sq ft reception at 10 ft is 150 x 10 = 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. A 600 sq ft front of house that is genuinely open, at 10 ft, is 6,000 cubic feet, about 170 cubic metres. Assume 9 to 12 ft in a clinic rather than the 14 or 16 you would assume in a showroom, and write down which you assumed, because the difference between 9 and 12 is a third of the air.
Now set those numbers against the Vaayu, which 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. Forty-two, seventy-one, a hundred and two or a hundred and seventy, against a thousand. This is the recurring honest finding of the whole bank: the volume in a foot clinic that actually needs scenting is small, which keeps making the answer cheaper than the budget. A single reception is very often an ultrasonic and a bottle. The Vaayu earns its ₹11,999 when the front of house is large and genuinely open, when it needs to run all day on a timer without anybody touching it, or when you specifically want a waterless machine because there is to be no water tank anywhere near a clinical area.
Then the four installation questions, which are boring and are the ones that go wrong. Is there a live socket where the machine should be? The Vaayu runs on DC 12V / 1A at 5W and is mains powered, so it needs a socket rather than a battery, and the socket you have is often not where the machine ought to be. Is the position out of the direct airstream? A machine in front of a supply grille or beside a return is being either blasted or extracted, and both produce a room that is wrong in a way no setting fixes. Is it in the corridor because that is where the free plug is? A corridor is a fifteen-second room connected to everything, so scenting it means dosing the corridor while reception gets the leak and every treatment room door gets tested each time somebody walks through. And is the timer set to your opening hours only, so nothing is running at three in the morning into a closed building?
Finally, set the level and then defend it. Start lower than feels like it is working. Write the setting on a card and tape it to the machine, because a written number is the only real defence against an adapted nose. Do not touch it for a fortnight. Judge it from the doorway on a morning the clinic has been shut, not from behind the desk at five in the afternoon. Ask three people who have just come in off the street what they notice, before you tell them a diffuser exists. If two of them can name a product, come down a notch. And when somebody says it has faded after a week, it almost certainly has not - their nose has adapted, and the correct response is to ask a stranger rather than reach for the dial.
If, having done all of this, the honest conclusion is that the front of house does not need anything yet, that is a legitimate answer and a fairly common one. Wait a quarter. The list does not expire.
- Give footwear a hard, ventilated home away from the seating and the treatment couch.
- Get a written answer: does the AC bring in outside air, or only recirculate?
- Sort upholstery, laundering, AC filters, the drain tray and any damp.
- Write down the unscented rooms, then size for the front-of-house volume only.
What to buy at the end of the list, and why it is usually smaller than the budget
Assume the list is done, the unscented rooms are marked on the plan and you have a number for the connected volume of the front of house. Now the register, which is the easy part and the part everyone starts with.
In a clinic the field narrows before taste gets a say: clean and unsweet reads right, and sweet or plush reads as covering something - a particularly unhelpful impression in a building where the patient already knows what happens. There are seven registers 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.
White Tea Serenity is white tea, aloe and cedar - clean, weightless and spa-like, the most transparent of the seven, and the one most likely to be received as cleanliness rather than as fragrance. Quiet Luxury is white tea, bergamot and cedar - hushed and polished, and the safe default if you have no strong view, because it is neutral across a mixed patient list and never becomes the thing somebody is thinking about while they wait. Forest Suite is cedarwood, vetiver and green leaves - grounding and biophilic green, and the right answer for timber, concrete, planting or a sports-medicine look. Tea Garden is jasmine, green tea and white tea, the best floral option for a softer front desk, a step warmer than the white-tea pair and therefore wanting a lower setting. Warm Welcome is citrus, floral and sandalwood, genuinely a threshold register for a family practice, used with more restraint than a hotel would apply. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and the wrong register for a clinic. Lobby Bar is citrus, pepper and amber, bold and after-dark, and has no real home in a foot clinic.
SOSA does not publish comparative throw or longevity figures for the seven and this page will not invent them. Connected volume, ceiling height, ventilation rate, soft furnishing and the setting you choose decide how a register behaves in your reception far more than the blend does, and anybody ranking the seven on strength in a room they have never stood in is guessing at your expense.
Two practical notes that follow from the list. First, if you have just completed the six fixes, test registers after the fortnight rather than during it - the pack of seven 15ml bottles at ₹1,799 is for judging in your own air, and the air you are judging should be the air you are going to keep. Second, if your waiting room is heavily upholstered, the fabric takes up your register too, so it reads quiet on day one and then builds over weeks; set lower than instinct suggests and judge any change after a fortnight rather than an afternoon.
And the room list does not change no matter what you buy: reception, waiting and the arrival corridor only. Nothing in treatment cabins, procedure or nail-surgery rooms, the casting or orthotics area, the sluice or the instrument room, or any cabin with a patient mid-treatment. The treating clinician's judgement about those rooms and about their own patients overrides all of it, in either direction.
| Scent | Why it suits the mood |
|---|---|
| Footwear and fresh air · do these two first | A hard, ventilated, wipeable shoe home away from the seating and the couch, and a written answer from your AC contractor on whether the system brings in outside air or only recirculates. These are the two highest-value items in the whole vertical: one contains the only source that is renewed by every appointment, the other is the only step in the sequence that removes anything at all. |
| Fabric, filters and damp · the slow ones | Wipeable seating or washable covers with a spare set; a laundering rotation with a named owner and a date rather than a clean done on notice; AC filters and the drain tray genuinely inspected rather than signed off; and damp treated as a repair. These fail slowly and invisibly, which is why they need a diary rather than an intention. |
| The two written decisions · before you order | Mark the permanently unscented rooms on the floor plan as a specification, so nobody helpfully corrects the blank in month seven. And set the sensitivity arrangement as policy: asked at booking, with off as a state anyone can set for a named room without a discussion. Your own staff are in that air eight to ten hours a day and are the most exposed people in the building. |
| Only then, the machine · and it is usually small | Front of house area times ceiling height, divided by 35.3, stopping at any door that stays shut: 42, 71, 102 or 170 cubic metres against the Vaayu's approximately 1000. Check there is a live socket, keep it out of the direct airstream and out of the corridor, set the timer to opening hours, write the setting on a card. A ₹749 reed or an ₹1,899 ultrasonic with fragrance from ₹299 is often the whole answer. |
Now the purchase, sized to the number you calculated rather than to the budget you set before you started.
For a single reception, an ultrasonic is usually the whole thing: the SOSA Boond at ₹899 for a small enclosed front desk, or the SOSA Sukoon at ₹1,899 for a normal reception and waiting area, both running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999. For a large waiting area that runs from nine in the morning to eight at night, the SOSA Megh at ₹3,499 with its 6 litre tank saves somebody refilling at lunchtime. And if you want no plug, no noise and nothing anybody can turn up on a difficult afternoon, the SOSA reed diffusers run their own registers: Morning Freshness at ₹749 is Malabar lemon, mint and eucalyptus, the freshest and most obviously clean-reading; Mountain Breeze at ₹849 is Himalayan pine, sage and cedar, closest to a clinic's woody register; 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, lovely at home and wrong for 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.
For a larger connected front of house, the SOSA Vaayu at ₹11,999 is the commercial answer, and in a clinic its defining feature is what it does not involve: waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue anywhere near a clinical area. Approximately 1000 cubic metres of connected air; SOSA's own copy also states 2,000 to 3,000 sq ft scented evenly; a 400ml tank; freestanding, wall or HVAC mounting; DC 12V / 1A at 5W, so it needs a live socket; CE, RoHS and SGS; Bluetooth app and timer so it runs your opening hours and nothing else. It is an ambient fragrance product rather than a clinical, medical 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 machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - run waterless nebulising oil. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine, so if you are choosing a register on an ultrasonic today but expect to move up later, say so on WhatsApp before you buy.
To fill in the reasoning behind individual items on the list: the three categories that get sold into the same conversation are separated by verb in ventilation vs air purification vs fragrance for a foot-care clinic. The upholstery item has a whole page of physical detail behind it in whether upholstered waiting chairs and clinic fabrics hold onto odours. And if you want the whole thing framed as two projects with two budgets and two owners rather than one long list, that is how to separate odour management from ambient fragrance in a podiatry 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, and they are yours rather than ours. 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.
- 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.
