So this page is a procedure rather than an argument. It gives you the document to write - what is in it, line by line - the method for judging the thing that is being standardised, and then the four failure modes with a written countermeasure for each. If you already accept that all your clinics should run the same register, and you should, this is the page about actually making that true across three sites and four years rather than across a good intention in March.
One thing to be clear about before the detail, because it is the most common misunderstanding in multi-site scenting. The standard is not the setting number. Your branches differ in volume, ceiling height, ventilation and door layout, so identical settings give you different rooms. What you standardise is the perceived level - what a person with a fresh nose meets in the first three seconds through the door - and each branch is calibrated to that target independently, with its own number recorded separately.
And the standing order applies at every site, which means it goes in the document too: source, then ventilation, then cleaning and laundering, then fragrance. Reception and waiting only. Nothing behind the treatment room doors. Fragrance adds scent and does not remove odour, no SOSA product is a medical device, and the treating clinician at each site overrides the group standard in their own rooms.
What should the standard actually specify? A perceived level, not a number. The wording that travels between sites is: a person arriving with a fresh nose from outside should register the room as considered rather than as scented within the first three seconds, and should not be able to name a product from the doorway. Each branch is then calibrated to hit that description on its own, because a 250 sq ft reception at 10 ft holds about 71 cubic metres and a 300 sq ft one at 12 ft holds about 102, and the same setting will not produce the same room.
Who should own it at each clinic? One named person per site, and one named person across the group who owns the review. Not "reception", not "the practice manager" as a role that changes hands without a handover - a name on the document, with the setting, the position of the machine and the date beside it. Standards that belong to everybody belong to nobody, and in a multi-site group the failure is almost never disagreement. It is that nobody was the person whose job it was to look.
The document. One: the register, named, one line, with the note that it is the same at every site. Two: the rooms it is used in, by name, at each clinic - "reception and waiting" at branch one, "reception, waiting and the arrival corridor" at branch two, because the sites are not identical and the list should say so. Three: the rooms that are permanently at zero and why, because the reason is what makes the rule survive a change of staff - treatment cabins, procedure and nail-surgery rooms, any cabin with a patient mid-treatment, the casting and orthotics area, the instrument bench and the sluice. Four: the perceived-level target, written as a sentence rather than a number. Five: how that target is judged, written as a method rather than as an instinct. Six: the calibrated setting for each branch, recorded separately, with the date it was set and the name of the person who set it. Seven: the owner at each site, by name, plus one person across the group who owns the review. Eight: the review date, and what triggers an unscheduled review - a fit-out change, an air-conditioning service, a change of season, a new machine, or a sensitivity report.
The judging method, because line five is the one that most groups leave vague and it is the line the whole thing rests on. Judge from outside, with a nose that has been in different air for at least twenty minutes. Judge on a morning that clinic has been shut, not at five in the afternoon. Judge in the first three seconds through the door, because that is the only moment your patients get. Then apply the naming test: ask three people who have just come in off the street what they notice, before telling them a diffuser exists. If nobody mentions it and nobody is bothered, that branch is on target. If two of three can name a product, that branch comes down a notch. Nobody who has been standing in the building judges the building.
The two things people forget to standardise, and both change the room more than the register does. The first is the housekeeping product: a pine surface cleaner at one branch and an unfragranced one at another gives you two different receptions no matter how carefully you matched the diffusers, because a clinic that has just been cleaned smells of cleaning. Put the cleaning product on the same page as the register. The second is footwear storage: source comes before scent, so a group standard that specifies a diffuser setting but not where shoes go at each site has standardised the wrong end of the problem.
Then the four failure modes get a written countermeasure each, and they are the second half of this page. None of them is exotic and all four are inevitable, which is exactly why they belong on paper rather than in somebody's memory. A portion of every SOSA order supports girl-child education through Nanhi Kali.
The reason this needs a document rather than a conversation is that multi-site drift is not caused by disagreement. Nobody at branch three ever decides to abandon the group register. What happens is a sequence of small, individually reasonable acts by people who were not there when the decision was made: the machine gets moved off the shelf because the shelf was needed, the bottle runs out on a Friday and somebody improvises, the setting goes up one notch on a slow afternoon because a member of staff who had been in the building since nine could not smell anything. Each of those is defensible in the moment. Together, over two years, they produce three clinics that smell like three clinics.
A written standard is not bureaucracy in this context; it is the only thing that survives staff turnover, which in reception roles is faster than in clinical ones. The test of a good scent standard is whether a receptionist who joined last week can read it and do the right thing without asking anybody. That means it has to contain the reasons and not only the rules - "cabin two is at zero because a treatment room is small, the door is shut and the clinician is in there at close range all day" survives a new manager, while "cabin two: none" gets overruled by the first person who thinks it looks like an oversight.
The second thing worth saying is that the document should be short enough that people read it. One page. If it runs to four, the parts that matter get skimmed. Eight lines and four countermeasures is genuinely enough for a group of any size, and a group of ten clinics uses the same page with ten rows in the settings table rather than a longer document.
And the line that must be in it for reasons that outrank the brand: fragrance-sensitive patients are a standing arrangement rather than a favour at every site. Ask at booking rather than at the door. "Off" is a state anybody on any team can set for a named room without a discussion or a permission. A reported reaction is a recalibration signal, never a tolerance problem. Your own staff are in that air eight to ten hours a day at every branch and are the most exposed people in the group. And nothing in the document is clinical advice: the treating clinician at each site overrides the group standard in their own rooms, in either direction, and the document should say so in those words.
The one page you write, how the level is judged, and the four ways it falls over
There are three parts to this and they are best kept separate, because groups that muddle them end up with a long document that does not work. The first part is the record: what is written down, and it is shorter than people expect. The second is the method: how the thing being standardised is actually judged, which has to be a repeatable procedure rather than a matter of taste, or two people will apply the same standard and get different answers. The third is the countermeasures: the specific, named ways a multi-site scent standard falls over, each with something written against it.
What is not part of this, and is worth setting aside now: the argument for using one register across sites at all. That argument is a mechanism - consistency is what makes a signature, and a returning patient recognising your second clinic within seconds of the door is the whole effect - and it is made properly on its own page. This page assumes you have accepted it and are now trying to make it true in practice, which is a different and harder job.
It also assumes the thing that makes the job hard, so it is worth restating in numbers. Your branches are not the same 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 a 10 ft ceiling is 250 x 10 = 2,500 cubic feet, about 71 cubic metres. A 300 sq ft one at 10 ft is 3,000 cubic feet, about 85. The same 300 sq ft at 12 ft is 3,600 cubic feet, about 102. A 500 sq ft open front of house at 12 ft is 6,000 cubic feet, about 170, and a 750 sq ft one is 9,000 cubic feet, about 255. A three-clinic group can easily span 71 to 170 cubic metres across its receptions, which is well over a factor of two, before you have considered ventilation or how often the front door opens. That is why the setting number cannot be the standard.
And the boundary that applies at every site, which belongs in the record rather than in a supplier's memory: a coverage rating assumes one connected body of air, scent does not travel through a closed door, and each clinic is scented volume by volume. A treatment cabin of 80 to 120 sq ft at 9 ft is 720 to 1,080 cubic feet, roughly 20 to 31 cubic metres, and it is at zero at every branch in the group. The list of rooms that get nothing is as much a part of the standard as the register is, and in practice it is the part that erodes first.
1. The register. Named, one line, with the words "the same at every site". If it is one of the seven water-based Hotel Collection registers, name it exactly. If a site is on a different system - the ultrasonics run the water-based collection from ₹299 while the Vaayu runs waterless nebulising oil - the document has to say what each site is running and why they are not the same bottle, because otherwise somebody will one day try to put a ₹299 water-based bottle into a Vaayu.
2. The rooms it is used in, by name, at each site. Not "front of house", which means different things in different buildings. "Reception and the waiting seating" at one branch; "reception, waiting and the arrival corridor" at another. Naming the rooms is what turns a principle into something a new person can follow.
3. The rooms that are at zero, and why. Treatment cabins, procedure and nail-surgery rooms, any cabin with a patient mid-treatment, the casting and orthotics area, the instrument bench, the sluice, and the staff room and WC as extraction rather than fragrance questions. Then one short sentence of reasoning: these rooms are small, the doors are shut, the clinician is in there at close range for eight to ten hours a day and dressings and instruments are open. The reasoning is the part that survives. A bare list gets overruled by the first helpful person who reads it as an omission.
4. The perceived-level target. In words. "A person arriving with a fresh nose from outside should register the room as considered rather than as scented within the first three seconds, and should not be able to name a product from the doorway." That sentence is the standard. It is identical at every site and it is the only thing that is.
5. How the target is judged. The method, written out, so that two different people applying it get the same answer. It is factor two on this page and it belongs on the document verbatim rather than as a reference.
6. The setting at each branch, separately. A small table: branch, machine, setting, position of the machine in the room, date set, who set it. Six columns. This is the line that makes the difference between a standard and a wish, because it gives you a value to restore to when something drifts, and it makes drift visible - a setting that has moved three times in six months is telling you something about that room or that nose.
7. The owner. One named person at each site, and one named person across the group who owns the review. Not a role that changes hands silently. A name, with a handover note when it moves.
8. The review date, and the triggers. A scheduled review - quarterly is sensible and monthly is better in the first year - plus the events that force an unscheduled one: a fit-out or furniture change, an air-conditioning service or duct clean, the change of season, a new machine, a change of housekeeping product, or any sensitivity report from a patient or a member of staff.
Two additions that are not about the diffuser and change the room more than it does. Put the housekeeping product on the same page, because a pine cleaner at one branch and an unfragranced one at another produces two different receptions regardless of the register. And put the footwear storage arrangement on it, because source comes before scent and a group that has standardised its diffuser setting but not where shoes go has standardised the wrong end.
Who. Not somebody who has been in the building. Olfactory adaptation happens within minutes of arriving somewhere, it is completely ordinary, and it is the single biggest cause of over-scented commercial space in India. The person judging must have been in different air for at least twenty minutes - arriving for the day, coming back from lunch outside, or visiting from another branch. A member of staff who has been at the desk since nine cannot assess the desk at four, and no amount of conscientiousness fixes that. This is also why a group has an advantage a single clinic does not: your branch managers can judge each other's rooms, arriving with genuinely fresh noses, which is the cheapest and most reliable audit available to you.
When. On a morning that clinic has been shut - first thing, before the day has happened to the room. That is the coldest and most honest reading, and it is also the reading your first patient of the day gets. Judging at five in the afternoon tells you about a room that has had a full list through it, and setting a level at five is how a clinic ends up running at roughly double what it should. Judge each branch at the same point in its own week so the readings are comparable.
What question. Three seconds, and then the naming test. In the first three seconds through the door, does the room read as considered, or does it read as scented? Then ask three people who have just come in off the street what they notice, before telling them there is a diffuser. If nobody mentions it and nobody is bothered, the branch is on target. If two of the three can identify it as a product - "is that lemongrass", "that is the same as my hand wash" - the branch comes down one notch, and it comes down at that branch only rather than across the group.
Then two rules about acting on the verdict, which are where most groups go wrong. Change one notch at a time and then wait a fortnight. A room takes days to settle and a nose takes minutes to adapt, so a same-day second adjustment is always the adapted nose talking. And every change gets logged on line six of the document with the date and a one-line reason, which is how you tell the difference between calibration and creep.
The single most common false alarm is worth naming, because it drives more bad adjustments than anything else. Somebody reports that a branch "has faded". Almost always it has not; the person reporting it has adapted, and the level that was correct in week one now reads as nothing to the human being most exposed to it. The written response is to ask somebody who has not been in that room today, not to reach for the dial. If three separate arrivals also say they notice nothing at all, you have a genuine signal and you can move up one notch, once, and leave it for another fortnight.
And the rule that is never negotiable, at any branch, for any reason: nobody reduces ventilation, closes a vent or turns down extraction so the fragrance lasts longer. A well-ventilated clinic is genuinely harder to scent and it is the better clinic, particularly in a building where people take their shoes off. That belongs on the document in those words, because in a group it is exactly the sort of local improvisation that spreads.
Failure one: a new staff member moves a machine. The shelf was needed, the socket was wanted for a phone charger, the machine looked untidy on the desk, somebody was cleaning and put it back somewhere else. Placement is not decoration - a machine under an air-conditioning return has its output pulled out of the room, a machine in a supply airstream gets thrown across it, and a machine behind a monitor or inside a cupboard does very little. The countermeasure: the machine's position is part of the record, described in words on line six - "on the shelf to the left of the desk, about 1.2 metres up, not below the return grille" - with a photograph taped inside the cupboard door or stuck to the back of the document. Anyone can then put it back without asking. And the standard says plainly that the position is not to be changed without telling the site owner, because moving it is a bigger change than a notch on the dial.
Failure two: a branch runs out and substitutes something. It is a Friday, the bottle is empty, there is a full list on Saturday and there is a shop two doors down. Nobody is being disloyal; somebody is solving a problem. Two months later that is what branch three smells of, and it is the fastest way a group loses its signature. The countermeasure: write the rule in one sentence - a different product is never an acceptable substitute, and nothing at all is. A week of an unscented reception costs the group nothing, while a month of the wrong register costs it the only thing consistency was buying. Then make the rule easy to follow: ordering runs through one route rather than per site, each branch has a named person who raises it, and the WhatsApp line at +91 96192 18531 exists for exactly this. Anything about what to keep on hand is a conversation there, not a number this page will invent.
Failure three: a setting gets nudged up and never comes back down. This is the quietest one and the most damaging. Somebody who has been in the building since nine cannot smell it at three, moves it up a notch, and does not move it back. Six weeks later somebody else does the same. The room now runs at a level nobody chose, and every person who set it was certain they were correcting an under-dose. The countermeasure: three parts. The calibrated value is written on the document, so there is always a number to restore to. Every change is logged with a date and a one-line reason, so creep becomes visible as a pattern rather than invisible as a series of moments. And the monthly or quarterly check is done by somebody arriving from outside - ideally the manager of another branch - because the whole failure is caused by an adapted nose and only a fresh one can catch it.
Failure four: one branch quietly stops. The machine was switched off during a deep clean in February and never switched back on, or it stopped working and nobody escalated it, or the reed ran out in April and the reorder never happened. Nobody at that site notices, because the room changed by degrees and they are in it every day. The countermeasure: a yes-or-no line in the review - "is it running, and at the recorded setting" - owned by one person across the group rather than by each branch, and checked on a calendar date rather than when somebody remembers. A single question on a quarterly walk-through catches this permanently, and nothing else does.
And a fifth item that is not a failure mode but belongs beside them, because it is the one thing in the document that outranks the standard: the off switch. Any member of staff at any site can set a named room to off for a fragrance-sensitive patient, without a discussion and without asking permission. Sensitivity is asked about at booking rather than negotiated at the door. A reported reaction is a recalibration signal, never a tolerance problem, and it triggers an unscheduled review at that branch. The treating clinician at each site overrides the group standard in their own rooms in either direction, and if a clinician wants the front of house unscented too, that is the end of the conversation and a perfectly good answer.
- Write the one page: register, rooms used, rooms at zero and why, and the target.
- Calibrate each branch separately and record its setting, position, date and setter.
- Name an owner at every site and one person who owns the group review.
- Diarise the review, and write the four countermeasures next to the settings table.
What goes in the register document, line by line
The register line on the document should take twenty minutes to decide and then never be reopened, so it is worth deciding it well. The clinic filter comes first and it is the same at every site: clean and unsweet reads right in a clinical room, because sweetness or plushness over a warm enclosed space reads as covering something, and a foot clinic reception cannot afford that impression at any branch.
The seven water-based Hotel Collection registers, honestly mapped for a group. Quiet Luxury - white tea, bergamot and cedar, a hushed and polished lobby calm - is the strongest group choice, because a multi-site register has to sit comfortably in interiors that are not identical and it is the most neutral of the seven. White Tea Serenity - white tea, aloe and cedar, clean, weightless and spa-like - is the other natural answer and the best one if every front of house in the group is pale, light and minimal. Forest Suite - cedarwood, vetiver and green leaves, grounding and biophilic green - is right if the group has a shared sports-medicine or timber-and-concrete identity. Tea Garden - jasmine, green tea and white tea, a serene tea-and-jasmine calm with the jasmine sitting inside the tea - is the softest option that still passes the filter and wants a lower setting than the white-tea pair. Warm Welcome - citrus, floral and sandalwood, warm and gracious hospitality - suits a family-practice group used with restraint. Old-World Glamour - amber, violet and woods, plush and evening-elegant - is beautiful and belongs in a different kind of building. Lobby Bar - citrus, pepper and amber, bold and after-dark - has essentially no home in a foot clinic.
Each is SOSA's own hotel-inspired interpretation, and SOSA is independent and not affiliated with, endorsed by or connected to any hotel brand. That sentence is worth having in the document too, because brand language travels between sites and gets embellished.
Test the shortlist in more than one branch before committing, using the pack of seven 15ml bottles at ₹1,799. A register that is right in the pale minimal reception at site one and slightly odd in the darker, fabric-heavy one at site two is not the group register, and a group register is what you are choosing. Judge each on day five rather than the first afternoon.
What the document should not contain, and what this page will not supply, is any ranking of the seven on measured throw or longevity. SOSA does not publish that comparison and it would not survive contact with three different rooms - connected volume, ceiling height, ventilation rate, soft furnishing and setting swamp any difference between blends, which is the same finding that makes per-branch calibration necessary in the first place.
Two further lines for the register section of the document. First, if any branch is on a Vaayu rather than an ultrasonic, record that it runs waterless nebulising blends rather than the ₹299 water-based bottle, in those words, so that nobody attempts the substitution. Second, if the group is considering a bespoke composition made only for the practice: that is a real SOSA service, discussed on WhatsApp rather than priced on a page, and the cheaper honest answer comes first - one of the seven held consistently already is a signature, because consistency makes a signature and uniqueness does not. A group that has not yet held one register steady across three receptions for a year is not ready for a bespoke one, and will not be rescued by it.
And the line that never changes at any branch: the treatment cabins, the procedure and nail-surgery rooms, any cabin with a patient mid-treatment, the casting and orthotics area, the instrument bench and the sluice get no register at all. In a group, that is the line most likely to be quietly eroded at whichever site has a spare socket and a helpful new team member, which is exactly why it is written down with its reasoning attached.
| Scent | Why it suits the mood |
|---|---|
| A machine gets moved · countermeasure | Position is part of the record, described in words on the settings line - which shelf, roughly what height, and not below the return grille - with a photograph taped inside the cupboard door. Anyone can restore it without asking. The document also says the position is not changed without telling the site owner, because moving a machine changes the room more than a notch on the dial does. |
| A branch substitutes something · countermeasure | One sentence, written: a different product is never an acceptable substitute, and nothing at all is. A week of an unscented reception costs the group nothing; a month of the wrong register costs it the consistency that was the whole point. Then make the rule followable - one ordering route rather than per site, a named person at each branch, and the WhatsApp line for anything urgent. |
| A setting creeps upward · countermeasure | Three parts. The calibrated value is on the document so there is always a number to restore to. Every change is logged with a date and a one-line reason, so creep shows up as a pattern rather than a series of forgettable moments. And the periodic check is made by somebody arriving from outside, ideally another branch's manager, because an adapted nose caused the problem and only a fresh one catches it. |
| A branch quietly stops · countermeasure | A yes-or-no line on the review - is it running, and at the recorded setting - owned by one person across the group rather than by each site, and checked on a calendar date rather than when somebody remembers. Switched off during a deep clean in February and never switched back on is the commonest version, and a single question on a quarterly walk-through catches it permanently. |
On equipment, the standard should be honest that the machine is a means rather than the standard itself. Two branches with 71 and 85 cubic metre receptions - 250 sq ft at 10 ft is 2,500 cubic feet, and 300 sq ft at 10 ft is 3,000 - are two SOSA Sukoons at ₹1,899 each running the same water-based Hotel Collection register from ₹299, with 100ml refills at ₹999, and that uniformity makes everything else easier. A small enclosed front desk at a third site is a Boond at ₹899. A large front of house that runs nine to eight without anybody thinking about it is a Megh at ₹3,499 and its 6 litre tank.
Where one branch has a genuinely large open connected front of house - 500 sq ft at 12 ft is 6,000 cubic feet, about 170 cubic metres, and 750 sq ft at 12 ft is 9,000 cubic feet, about 255 - the SOSA Vaayu at ₹11,999 is the honest answer for that site. It is waterless cold-air nebulising of undiluted oil, so no water, no humidity and no wet residue in a clinical building; rated for approximately 1000 cubic metres of connected air; 400ml tank; freestanding, wall or HVAC mount; DC 12V / 1A at 5W, so it needs a live socket; CE, RoHS and SGS. For a group the Bluetooth app and timer are worth more than they are for a single clinic, because "scent the opening hours and nothing else" becomes a setting rather than a habit somebody has to remember - and a timer is one fewer thing on the review. The ducted machines above it, 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 rarely the right conversation in a foot clinic, because ducted air reaches everywhere the duct goes and most of your rooms are deliberately at zero.
And if a branch front desk wants no plug, no noise and nothing to switch off, SOSA reed diffusers from ₹749 are a legitimate entry on the settings table - Morning Freshness at ₹749 and Mountain Breeze at ₹849 read cleanest in a clinic - with one honest note on the document: a reed's level drifts down as the bottle empties across the 6 to 10 weeks it lasts, so a reed branch will match the group target less precisely than a machine branch, and the review has to allow for that rather than treat it as a fault.
To go deeper on the parts this page only touches: the argument for why every site should run the same register in the first place, and why identical settings will not give identical rooms, is made properly in whether both foot clinic locations should use the same signature fragrance. If a new site is still on a drawing, several of the calibration differences here can be designed out before they exist - that is planning scent-machine placement with your interior designer. And if one branch is small enough that the honest answer is a reed or nothing at all, the threshold is worked out in at what clinic size a podiatrist needs more than reed diffusers.
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 differ from branch to branch in your own group. That conversation happens with all your floor plans 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 - after consistency rather than instead of it.
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.

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.
