Three rooms, three completely different occupants, and one instinct to treat the building as a single space. The map that fixes this fits on one page and is worth more than the scent choice on it.
Quick answers — read this first
Should reception, treatment cabins and the exercise floor all smell the same? No. Three zones, three answers. Reception and the entrance carry the scent at the lowest level anyone could detect. The corridor is transitional - it takes whatever drifts and has no source of its own. The cabins and the exercise floor are both at zero, for two different reasons. What decides which zone a room belongs to is the state of the person inside it: upright and free to leave, passing through, or unable to move away from the air in front of them.
Why are the cabins and the gym floor in the same zone? Because they reach the same answer, not because they share a mechanism. In a cabin the client is prone with their face in a cradle a few centimetres from vinyl for most of a session and cannot turn away from it. On the exercise floor nobody is trapped, but the air is moving too much and the occupancy load is rising too fast for any dose to mean anything. One room cannot escape the air, the other cannot hold it. Both end at nothing.
What is the deliverable here - a product or a plan? A plan, and specifically a drawing. Take your floor plan, shade zone one, zone two and zone three in three different tones, write the level next to each, and pin it where the person who restocks reception can see it. That page is what survives a change of staff. A scent choice made in a meeting does not, which is why nearly every drifting clinic plan I am asked to review was never written down in the first place.
The short answer
Short answer: No. Reception is scented at the lowest detectable level, the corridor is transitional and gets no source of its own, and both treatment cabins and the exercise floor sit at zero. Zones are decided by what the occupant is doing - upright and free to leave, passing through, or unable to move away from the air - rather than by room size. The map itself is the deliverable.
The pick: one source in zone one only: a Mountain Breeze reed at ₹849 for most receptions, or a SOSA Vaayu at ₹11,999 where zone one alone is genuinely large.
Next step: send your floor plan and we will shade the three zones on it and write the level beside each - ask for a clinic scenting plan.
Should all three - reception, treatment cabins and exercise floor - smell the same?
No, and the reason is not size. It is what the person in each room is doing. That is the whole basis of the zoning, and once you use it the map draws itself. Zone one is where the occupant is upright, clothed, free to move and free to leave. Your entrance, reception and waiting area. This is the only part of the building with a fragrance job, and the level is the lowest that is detectable standing in the doorway - if a client can name the scent, it is too high. Zone two is where nobody stops. The corridor that joins the front to everything behind it. It takes whatever drifts from zone one and has no source of its own, ever. And here is the concession this page owes you, because it is the part people find unsatisfying: the corridor will always be a compromise. It is too close to the scented room to be clean and too close to the unscented rooms to be scented, and there is no arrangement of doors and distances that makes it perfect. It is a buffer, and a buffer is by definition the place where two conditions meet imperfectly. Zone three is everything the occupant cannot control. Treatment cabins, adjustment and examination rooms, and the exercise floor. All at zero. The two halves of zone three arrive there by different routes, which is worth knowing because it stops you making an exception for one of them. In a cabin, a client spends much of the session prone with their nose a few centimetres from upholstery they cannot turn away from, for thirty to sixty minutes. Whatever is on the table dominates whatever is in the room, and a level that reads as subtle standing at reception is not subtle face-down in a cradle. On the exercise floor, nobody is trapped, but the air is moving and the occupancy load is climbing, so a dose there is not a level at all - it is a range you cannot predict. One room cannot escape the air; the other cannot hold it. Both end at nothing. What you should actually produce from this page is not a purchase. It is a drawing: your floor plan with three tones on it and a level written beside each zone, pinned where whoever restocks the reception can see it. That page is the thing that survives a change of staff, and almost every drifting clinic plan I am asked to review turns out never to have been written down. Fragrance here is an ambience decision like lighting, seating or flooring, working alongside ventilation and cleaning rather than instead of them. SOSA products are not medical devices, we make no claim that scenting affects bookings, retention or spend, and the clinician's judgement overrides any plan.
No. Reception is scented, the corridor takes drift only, and cabins and the exercise floor are both zero. Zones follow what the occupant is doing, not room size, and the shaded map is the actual deliverable.
One source, and it belongs in zone one. A Mountain Breeze reed at ₹849 covers most receptions completely. The SOSA Vaayu at ₹11,999 is for a zone one that is genuinely large on its own.
The hardware question is small here because only one of your three zones is in scope, and zone one is usually the smallest of the three by volume. These two are for the centres where it is not.
Waterless cold-air nebuliser, 1000m³ rated coverage, roughly 2,000-3,000 sq ft, ₹11,999. Adjustable intensity, run windows and a key-lock. Sized on zone one only - cabins and the working floor never enter the calculation. Under 38dB, freestanding or wall and HVAC mounted.
HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, ₹25,999, 800ml reservoir, programmable schedules, under 42dB. Almost no clinic reaches this on zone one alone, which is exactly the point of measuring zones separately.
₹11,999, 1000m³ rated coverage, 400ml tank lasting 90+ days, Bluetooth app plus onboard buttons, 1h/4h/8h/24h timers, adjustable intensity, auto-stop, key-lock, under 38dB, 5W. Waterless, so nothing is added to the air and no film is left on equipment. CE, RoHS and SGS are electrical and compliance marks, not medical approval. Made in India.
Each zone below is defined by a person rather than by a room, which is what makes the definitions travel between buildings. Apply them to your own plan and the shading takes about ten minutes.
1
Zone one
Upright, clothed, and free to walk out
Entrance, reception and waiting area. The person here is sitting or standing, dressed, in control of where they are, and able to move to another chair or step outside if they want to. That combination is what makes a fragrance defensible at all: exposure is short, voluntary and escapable. The level is set at the bottom of the detectable range, and the test is identification rather than pleasantness. If a client can tell you the room smells of lemon, you are above where you want to be. Set the number for the person who is in this zone longest, which is never a client - it is whoever sits at the desk for nine hours, and if they say it is too much then it is too much.
Tip: Judge zone one from the doorway with a cold nose, not from behind the desk. By the time you are sitting there you have adapted.
Where zone one is genuinely large, the Vaayu covers it from a single wall or HVAC-mounted unit rather than several smaller bottles competing across it.
The corridor. It has no source, and it never gets one, because anything placed there is both a leak into the cabins and a waste into the reception. What it does have is a job: it is the buffer that lets zone one and zone three coexist in one building. Distance, doors and time do that work - a longer run is better than a short one, a door that closes is better than an opening, and a source scheduled to stop before the busiest part of the day accumulates less into it. The honest position is that this zone is always a compromise. It will smell faintly of zone one at the near end and of nothing at the far end, and the transition will not be tidy. That is acceptable. A buffer is meant to be a gradient.
Run windows on the Vaayu are the one real lever on corridor drift: less running time is less accumulated into the buffer.
The cabins and the exercise floor both sit at zero, and the reasons are worth keeping separate so that neither gets an exception. A cabin holds someone prone, often partly undressed, with their face in a cradle centimetres from vinyl, unable to turn away, for thirty to sixty minutes. That is the highest-exposure, lowest-control position in your building, and a dose that reads as subtle at reception is nothing like subtle there. The exercise floor is the opposite situation with the same conclusion: the occupants are free and mobile, but the air is moving and the load is rising, so no number you set behaves like a number. Trapped air on one side, uncontrollable air on the other. Both end at nothing, and writing both into the map as an explicit zero is what stops somebody treating them as unfinished rooms.
Tip: A combined consultation-and-treatment room is a treatment room. It goes in zone three whole, not half.
The Vaayu's key-lock protects the map as much as the level: a locked unit is a unit nobody relocates towards zone three.
A zone is not a room, it is a description of the person standing in it. Two rooms of identical size can belong to different zones and usually do.
This is why floor area is such a poor guide in a clinic. The largest space in the building is often the one that gets nothing, and the smallest is the one everything is sized for.
Sized on zone one alone: cabins and the working floor are excluded from the volume calculation, which usually moves the answer a full step down the ladder.
This is the version to copy onto your own floor plan. Three tones, three levels, and a note beside each about why - because a rule with its reason attached is the one that survives.
The SOSA plan
The three-zone map for a combined centre
Zone
The occupant, and therefore the answer
Zone one · entrance, reception, waiting area
Upright, dressed, free to leave, there for twenty minutes. Scented at the lowest detectable level. One reed under about 750 sq ft, a machine only if this zone alone is genuinely large. View →
Zone two · the connecting corridor
Nobody stops. Transitional, drift only, no source of its own, and permanently a compromise. Distance, door discipline and shorter run windows are the only levers on it. View →
Zone three (a) · treatment, adjustment and examination rooms
Prone, often partly undressed, face in a cradle, unable to turn away, for up to an hour. Zero, written as a zero. A combined consultation-and-treatment room belongs here whole.
Zone three (b) · the exercise and rehabilitation floor
Mobile and working, in air that is moving and a load that is climbing. Zero, because no dose set there behaves like a dose. Air changes, laundry turnaround and wipe-down are that room's real controls.
The map is the part that travels: scent and dose can differ between sites, but the list of rooms at zero should be identical everywhere and written down once.
The largest room in the building gets nothing and the smallest gets everything, because a zone is a description of a person rather than a measure of a floor.

Zone one, and only zone one
Measured on its own, most zone ones are smaller than the lease suggests
Everything below is sized on zone one measured by itself, with zones two and three excluded entirely. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Most clinics measure zone one on its own and find a reed at ₹749-₹849 or a Sukoon at ₹1,899 is the whole answer, which is the main practical benefit of zoning before shopping. Fragrance is an ambience decision like lighting or seating, with no health, therapeutic or clinical claim of any kind. It works alongside ventilation, cleaning and clinical protocol, never instead of them, and SOSA products are not medical devices. Treatment rooms and the exercise floor stay unscented, staff must be able to switch the source off in seconds, and the clinician's judgement overrides any plan. Ask for a clinic scenting plan and send the floor plan with it.

A note from Sonal
When somebody asks me whether all three should smell the same, what they usually mean is whether the building should feel coherent. It should - and a shaded map is how coherence is actually produced. A building that changes in a way you can predict reads as designed. A building that changes at random reads as one where nobody agreed anything.
The reason I keep insisting on the drawing rather than the decision is that I have watched too many good decisions evaporate. A practice agrees the cabins stay clear, and eighteen months later there is a bottle in cabin two because a locum brought one in and nobody could name a rule against it. The map is the rule. It costs nothing, it takes ten minutes, and it is the only part of this whole plan that is genuinely durable.
One source, in zone one, at a level nobody can name. We make no health, therapeutic or clinical claim of any kind, and no claim that scenting affects a practice commercially. Fragrance is an ambience decision, like lighting or seating. Treatment rooms and the exercise floor stay unscented, staff must be able to stop it in seconds, and the clinician's judgement overrides any plan. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What decides which zone a room belongs to?
The state of the person in it. Upright, dressed and free to leave puts a room in zone one. Passing through without stopping puts it in zone two. Prone, undressed, immobilised, or working hard in moving air puts it in zone three. Floor area does not appear anywhere in that test, which is why the biggest room is often the one that gets nothing.
Is a faint smell of reception in the corridor a failure?
No, that is what the corridor is for. It is a buffer, and a buffer is a gradient by definition - faint at the near end, absent at the far end, never tidy. What would be a failure is a source placed in the corridor itself, which leaks into the cabins and wastes into reception at the same time.
Should a combined consultation-and-treatment room be lightly scented?
No. It is a treatment room and it belongs in zone three whole. Half-measures in that room are the single most common mistake in this cluster, and the reason is that once a client is on the table their position and exposure are identical whether or not the room also has a desk in it.
Can the exercise floor be zone two instead of zone three?
No, and the distinction matters. Zone two is a place nobody stops; the exercise floor is a place people stay for forty minutes doing hard work. It gets no source of its own and it is not treated as a corridor either - it is written into the map as an explicit zero, so that nothing quietly appears in a corner of it.
What should the map actually look like?
Your existing floor plan, three tones of shading, a level written beside each zone, and a date. Pinned somewhere the person who restocks the reception can see it, and given to every new member of staff. That is the whole deliverable, and it is worth more than the choice of scent printed on it.
Only where zone one is facility-scale: one SOSA Angaan at ₹25,999 covers roughly 8,000-10,000 sq ft, and zones two and three still stay out of the figure.
SOSA — Clinic Scentingthe three-zone map for reception, cabins and the exercise floor
Zone one scented at the lowest detectable level, zone two transitional and always a compromise, zone three at an explicit zero. Sized on zone one alone, which for most clinics means a reed at ₹749-₹849. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
