Why not just turn the level down on the rehab floor instead of off? Because a low setting in an unstable room is not a low level - it is an unpredictable one. The same source reads as nothing at nine in the morning and as noticeable at six in the evening, when the room is already carrying the most. You have not bought a quiet floor, you have bought a variable one. There is also the person who is on that floor all day: the trainer or therapist working there gets far more exposure than any client, and they get no say in it unless you build one in.
Will clients notice that the gym floor smells different from reception? Yes, and that is the intended result rather than a fault. A building is allowed to change as you move through it, in the same way the lighting and the flooring change. What reads badly is inconsistency within one kind of room - two similar spaces at two different levels. What reads as design is a clear step between a waiting area and a working floor, because the two rooms are obviously doing different jobs.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, described by the manufacturer as approximately 2,000-3,000 sq ft, with a 400ml refillable tank lasting 90+ days depending on intensity and run hours, Bluetooth app and onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, DC 12V/1A at 5W (roughly 1.5 units of electricity a month on a ten-hour daily schedule), freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, and also runs standalone wall-mounted or lay-flat. Ambient scent is an interior and hospitality decision: it works alongside proper ventilation, cleaning and clinical protocol and is not a substitute for any of them, it is not a medical device, and SOSA makes no health, therapeutic or treatment claim of any kind and no claim that fragrance affects bookings, retention or spend. CE, RoHS and SGS are electrical and compliance marks, not medical approval. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation. Prices and availability are subject to change - see the live product pages.
The question assumes the dial runs from quiet to loud and the rehab floor sits somewhere along it. It does not sit along it - it sits at the end of it, and the end of the dial is a legitimate specification.
Quick answers — read this first
Should an active rehab area have a different fragrance intensity from reception? Yes. Reception runs at the lowest level that is detectable in the doorway, the corridor takes drift only, and the active floor runs at zero. Zero is a setting, written into the plan alongside the others, and it is the only one that holds. A room where people are working has a moving air volume and a rising occupancy load, so any number you set there is a number for that minute rather than for the day.Why not just turn the level down on the rehab floor instead of off?

The short answer
Short answer: Yes - and the correct intensity for an active rehabilitation floor is zero. Zero belongs in the written specification next to the other numbers rather than being left blank. On a floor where people are working, air movement and rising occupancy load make any dose unholdable, so a low setting is simply a variable one. The contrast between a scented reception and an unscented floor is intended.
The pick: one source in reception only - a Mountain Breeze reed at ₹849, or a SOSA Vaayu at ₹11,999 where the front-of-house volume genuinely justifies adjustable intensity.
Next step: write your three numbers down and send them to us with the plan, and we will tell you if the middle one is doing anything - ask for a clinic scenting plan.

Straight answer
Should the active rehabilitation floor run at a different intensity from reception?
Yes, it should, and the intensity it should run at is zero. I want to be precise about what that means, because it is not the same sentence as "we do not scent the gym". Zero is a setting. It goes into the written plan in the same column as the reception number and the corridor number, with the same weight, and it is reviewed at the same time. The difference between a specification that says rehabilitation floor: 0 and a specification that simply has no row for the rehabilitation floor is the difference between a decision and an oversight, and only one of those survives a staff change. Now the mechanism, which is why the number cannot be something small instead. Intensity is only meaningful if the volume of air it is dosing stays reasonably still. On an active floor it does not: fans, doors, people moving, and an occupancy load that climbs steadily from the first session to the last. Set a low number there and what you have actually specified is a range - absent early, noticeable late - and you will never know which end of it any given client met. Turning it up flattens nothing; it lifts the whole range, so the quiet hour becomes present and the busy hour becomes too much. There is a second reason, and it is the one I care about more. The person with the highest exposure on that floor is not a client doing a forty-minute block twice a week. It is the therapist or trainer who is in that room for eight or nine hours, breathing hard alongside the clients. Set the level for them, and the level for them is nothing. If a staff member says it is too much, it is too much, and on an active floor that conversation is far more likely than in a waiting area. The concession this page owes you: clients will notice the step between a reception that smells of something and a floor that smells of nothing. That is fine. A building is allowed to change as you walk through it, the same way the lighting and the flooring change, and a clear step between a waiting room and a working room reads as zoning rather than inconsistency. 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.
Yes - and the number for an active floor is zero, written into the plan rather than left blank. A low setting in a moving room is a variable one, not a quiet one. The step between zones is intended.
The only place an intensity number does anything is the front. One Mountain Breeze reed at ₹849 for a small reception, or the SOSA Vaayu at ₹11,999 where the front zone is large enough that a dial is worth having.

Where an intensity setting is worth paying for
A dial only helps in a room whose air holds still
Making an intensity a real number
A reed has one intensity and you change it by changing how many reeds are in the bottle, which is a coarse control but an honest one. If you want a number you can set, record and hold, that is what a machine is for - in the front zone, and only there.
For a front zone big enough to need a dial
SOSA Vaayu
Waterless cold-air nebuliser, 1000m³ rated coverage (roughly 2,000-3,000 sq ft), ₹11,999. Adjustable intensity, 1h/4h/8h/24h run windows, auto-stop and a key-lock so the number you agreed is the number still running. Waterless, so nothing is added to the air.
From ₹11,999
For a very large connected entrance area
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, ₹25,999, 800ml reservoir, metal body, programmable schedules, under 42dB. Rare in a rehabilitation centre once the working floor is excluded. Made in India, and we will say so before you buy one.
From ₹25,999
Why the dial ends at zero for an active floor
Three separate things break a fragrance level on a working floor. Any one of them would be enough on its own; together they make the number meaningless.
1
Reason one
A dose needs a still volume, and this room has not got one
Intensity is a rate: so much material released into so many cubic metres over so much time. That arithmetic assumes the cubic metres stay put long enough to be filled. On a rehabilitation floor they do not. Doors open onto the corridor, fans run, an extract system pulls if you have one, and people crossing the room drag air with them. The consequence is that the same setting produces a different concentration in the middle of the floor, at the mat station and by the door, and all three change through the day. This is not a limitation of a particular machine. It is what happens to any source in a room whose air is deliberately kept moving, which is exactly what you want that room to be.
Tip: Test it the cheap way before you believe me. Stand in three parts of your floor at three times of day. If the room already varies that much unscented, a dose will not hold in it.
The Vaayu's adjustable intensity is built for matching one stable volume precisely. That is the front of your building, not the working floor.
See SOSA Vaayu →
2
Reason two
A low setting is a variable setting, not a quiet one
The instinct when a room is difficult is to compromise: not off, just very low. On an unstable floor that produces the least defensible outcome of the three. Early in the day the room is empty, the air is relatively still and the low setting is at least detectable. By late afternoon the occupancy load has climbed, the room is already carrying its own smell, and your low setting is now sitting on top of it. Same number, entirely different experience, and no way to explain to a client why the building smells one way at ten and another at six. Off is the only setting on that floor that behaves the same at every hour, which is the whole reason it is the one I specify.
Where a stable volume does exist, the Vaayu's run windows let you hold a level for defined hours rather than pushing through the whole day.
See SOSA Vaayu →
3
Reason three
Set the level for the person who cannot leave the room
In every space I specify, I set the level for whoever is in it longest, and in a clinic that is almost never the client. On a rehabilitation floor it is the therapist or trainer who spends eight or nine hours there, moving and breathing hard alongside the people they are working with. Their exposure is many times a client's, and unlike a client they cannot decide to sit somewhere else. If they say it is too much, it is too much, and there is no version of that conversation where the correct response is to ask them to get used to it. Fragrance sensitivity is real and it is not something to negotiate with. No product I make is described as hypoallergenic or as safe for sensitive individuals, and I would rather be plain about that than reassuring.
Tip: Whoever is on that floor all day should be able to switch any source off in seconds without asking permission. If they cannot, the plan is wrong regardless of the number.
A machine with a physical off is easier to stop than a bottle that has to be carried out of the building. The Vaayu's key-lock also stops the level creeping up between reviews.

The SOSA principle
A specification with a blank row invites somebody to fill it in. A specification that says zero has already answered them.
Half the over-scented clinic floors I have walked started as an unwritten intention. Nobody decided to scent the gym; there was simply nothing on the sheet saying not to.
The three settings, written down
This is the whole specification for a centre with an active floor. It fits on a postcard, and it should be on one, because the value is in it being written rather than remembered.
The SOSA plan
Intensity by zone, including the zeros
| Zone | Intensity setting |
|---|---|
|
Entrance, reception and waiting area
|
The lowest level that is detectable standing in the doorway, and no higher. If a client can name the fragrance, this number is too big. View → |
|
Connecting corridor
|
No setting of its own. Whatever drifts from reception is what the corridor gets, and the plan says so explicitly so nobody adds a source there later. View → |
|
Active exercise and rehabilitation floor
|
Zero. Written as a number, reviewed like a number, and not revisited because somebody thought the room smelled tired at five o'clock. |
|
Treatment cabins and examination rooms
|
Zero, for a different reason: a client prone in a face cradle cannot turn away from the air in front of them, and forty minutes is a long time to be unable to. |
The full plan for a centre with a gym is in how to scent a clinic with an exercise and rehabilitation area, the evening odour curve is dealt with in my rehab area develops an odour by evening, and the three-zone map is drawn in reception, cabins and exercise floor. SOSA makes no health or clinical claim of any kind, and no claim that scenting affects how a practice performs commercially.
Three zones, three numbers, one of them zero
Send us your zone list and the hours each one is occupied. We will write the settings, including the blanks.
An unwritten zero is not a decision. It is an empty row on a sheet, waiting for somebody helpful to fill it in.

Under those sizes a reed at ₹749-₹849 sets its intensity by how many reeds you leave in the bottle, which is coarse but perfectly usable, and a Sukoon at ₹1,899 adds an off switch at the cost of putting a little water into the air. Nothing on this page is specified for an active floor. 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 we will write the numbers with you.

A note from Sonal
The word I keep coming back to with rehabilitation floors is written. Not decided, not agreed in a meeting - written, on the same sheet as everything else, with a number in the box. A plan that lists reception at its level and simply stops has not said anything about the gym, and a plan that has not said anything about a room will eventually have something put in it.
I have seen how that happens and it is never dramatic. A member of staff notices the floor smells tired on a Friday, there is a spare bottle in the store cupboard from the reception order, and by the following month there is a source in a corner that nobody specified and nobody can find a reason to remove. The fix costs nothing and takes one line: rehabilitation floor, zero.
The rest of this is ordinary and worth repeating. 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, and never a substitute for ventilation or cleaning. 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
Is unscented really an intensity setting, or just an absence?
It is a setting when it is written down and reviewed like the others, and an absence when it is not. The practical difference shows up months later: a written zero survives a change of staff and a spare bottle in the cupboard, while an unwritten one quietly gets filled in by somebody trying to be helpful.
Can I run the rehab floor at a very low level rather than nothing?
You can, but you will not get a low level - you will get a variable one. The floor is nearly empty in the morning and fully loaded by evening, so the same setting reads as absent and then as present. Off is the only value on that floor that behaves identically at nine and at six.
Does the contrast between a scented reception and an unscented gym look inconsistent?
No, it reads as zoning. Buildings change as you move through them - light levels, flooring, sound - and a step between a waiting room and a working room is a step between two obviously different jobs. What reads badly is variation between two rooms of the same kind.
Who should set the intensity in a centre with a rehabilitation floor?
Whoever spends the longest in each space, which is staff rather than clients. The receptionist sets the front number and the therapist on the floor sets theirs, and both of them keep a veto. A level a client meets twice a week is a different thing from a level someone breathes for nine hours.
Does the corridor between reception and the gym need its own number?
It needs a row on the sheet that says drift only. That is not the same as leaving it blank, and it prevents the most common creep of all, which is a source appearing halfway down the hall to bridge the gap between two zones that were meant to be different.
Three numbers, one of them zero
