Which department usually sets it? Neurological rehabilitation, if there is one - it works to the most conservative standard of the group. Where there is not, the long-dwell or geriatric side usually does.
Does that not underserve the other departments? No, because nothing is lost. A sports patient is not disadvantaged by a quieter reception - the looser standards were permissive rather than requiring anything.

Facts verified 9 September 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 roughly 75-90 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, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification - electrical and compliance marks, and not any kind of medical, clinical or health approval. Being waterless it adds no moisture and leaves no residue on surfaces or equipment; refill supply should be confirmed with SOSA. 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. The SOSA Sukoon (₹1,899) is a 500ml water-based ultrasonic diffuser for a single room of roughly 270-320 sq ft, and the SOSA Boond (₹899) is its compact equivalent; both use the water-based Hotel Collection fragrance (15ml from ₹299, 100ml ₹999, 300ml ₹1,799), which is made for ultrasonic diffusers and is not reed diffuser oil. SOSA reed diffusers - Morning Freshness (₹749 / ₹1,249) and Mountain Breeze (₹849 / ₹1,349), or the two together as the Fresh & Grounded duo (₹1,548 / ₹2,548) - are alcohol-free and phthalate-free, with a 50ml bottle lasting 6-8 weeks and a 130ml bottle 14-18 weeks; 300ml and 500ml refills are ₹2,399 and ₹3,499. No SOSA product is a medical device, a therapy or a treatment. Ambient fragrance in a rehabilitation or recovery setting is an interior and hospitality decision only: SOSA makes no claim that it reduces pain, anxiety or stress, alters mood, aids or accelerates recovery, healing or rehabilitation, improves mobility, motivation, adherence, attendance or any clinical outcome, shortens perceived waiting time, purifies air, or affects bookings, retention or spend. It does not remove, neutralise or reduce sweat, disinfectant, laundry or equipment odour, and it is never a substitute for ventilation, cleaning, laundry, humidity control or infection control - a facility with a persistent odour has a source to find and fix first. Therapy and treatment areas are left unscented, including gyms and exercise floors, physiotherapy and occupational therapy areas, neuro-rehabilitation and stroke-rehabilitation therapy rooms, hydrotherapy, treatment cubicles, post-operative and recovery areas and changing rooms. Because patients in rehabilitation attend repeatedly over weeks or months, a named seating area away from the source is kept genuinely fragrance-free and offered rather than waiting to be requested, and where a patient, visitor or member of staff is sensitive to fragrance the correct response is to reduce or switch off. The treating clinician's judgement overrides any plan on this page. 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.
Like whichever of your departments has the strictest standard. A multidisciplinary building holds populations with genuinely different requirements - and in shared air the strictest of those is a floor, not a preference. An average serves nobody in the room.
Quick answers — read this first
What should a multidisciplinary rehabilitation centre smell like? Like whichever department in the building has the strictest standard. In shared air the strictest requirement becomes the floor for everybody, because an average serves none of the populations present.Which department usually sets it? Neurological rehabilitation, if there is one - it works to the most conservative standard of the group. Where there is not, the long-dwell or geriatric side usually does.
Does that not underserve the other departments? No, because nothing is lost. A sports patient is not disadvantaged by a quieter reception - the looser standards were permissive rather than requiring anything.
The short answer
Short answer: like whichever department has the strictest standard - in shared air that requirement is a floor rather than one option among several, and an average serves nobody.
The pick: a single register at the strictest department's level: Mountain Breeze (₹849) on one SOSA Vaayu (₹11,999) in shared front-of-house only.
Next step: list your departments and their standards side by side. The strictest one is your specification. Or ask for a facility scenting plan.

Straight answer
What should a multidisciplinary rehabilitation centre smell like?
Like whichever of your departments holds the strictest standard - and the reasoning is worth setting out, because the instinct in a shared building is to compromise and compromise is the wrong operation here. Start with the fact that makes this building different: it contains populations with genuinely different requirements. A neurological department works to the most conservative standard in this field. An orthopaedic one is restrained but ordinary. A sports department can be the most relaxed, because its population chose to be there and does not stay long. Those are three different answers, and a shared foyer cannot deliver three. Which is where most facilities reach for an average, and an average is exactly wrong. A level halfway between a neuro standard and a sports standard is too high for the neuro patients and pointless for the sports ones - it satisfies nobody in the room and it is not a compromise between two positions, it is a failure of both. The correct operation is not averaging. It is taking the maximum constraint. Because a strict standard is a floor rather than a preference. The neuro department is not expressing a taste when it asks for a very low level; it is stating a requirement. The sports department, by contrast, is being permissive rather than demanding - it can tolerate more, but it does not need more. Which means adopting the strictest standard in the building costs the looser departments nothing at all. No sports patient is disadvantaged by a quieter reception. No orthopaedic patient is worse off. The one department that would be harmed by the reverse decision is the one you are protecting, so the asymmetry decides it without anybody having to negotiate. Practically: list your departments and their standards side by side, and the strictest one is your specification. If there is a neurological or stroke service in the building, it almost always sets it - below identifiable, and frequently the answer is a neutral building, which then applies throughout. Where there is no neuro service, the long-dwell or geriatric side usually sets it. Then one register, one level, one shared front-of-house zone - Mountain Breeze at ₹849 or ₹1,349 on one SOSA Vaayu at ₹11,999 with the key-lock engaged. Every treatment area, gym, cubicle, hydrotherapy space and quiet room is never scented, in every department, and fragrance-free seating is named on the plan and offered at the first appointment. Fragrance is an ambience decision like lighting or seating: it is not a therapy and makes no contribution to recovery, healing, mobility, pain, mood, motivation or attendance, and SOSA makes no claim that it does. It works alongside ventilation, cleaning, laundry and infection control, never instead of them, and the treating clinician's judgement overrides any plan. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

The honest options for the public zone, sized to the floor rather than to the ambition. The images link to the product pages so every figure here can be checked.
A connected reception, family waiting and corridor of ~1,500-3,000 sq ft
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft - on one unit. In a rehabilitation facility its value is control rather than reach: the key-lock holds the level the furthest chair was judged to, so it survives every shift and every new receptionist, and the 1h/4h/8h/24h timer keeps it on facility hours rather than saturating an empty building overnight. Waterless, so it adds no moisture to a room full of mats and upholstery. 400ml tank, roughly 75-90 days depending on intensity and run hours, under 38dB, wall or HVAC mount.
From ₹11,999
The register - or the whole answer where reception is one seating zone
SOSA Mountain Breeze Reed Diffuser
Himalayan pine, sage and Indian cedar - the driest register SOSA makes and the rehabilitation default, because it reads as clean air rather than as a spa. Where reception is a single seating group, this bottle at the staff end of the desk at ₹849 for 50ml carries the register on its own, three or four reeds in, flipped weekly; 130ml at ₹1,349 lasts 14-18 weeks. Alcohol-free, phthalate-free, six fibre reeds, and carried out of the room in seconds if a patient asks.
From ₹849
Maximum constraint, not average
The instinct in a shared building is to compromise. Compromise is the wrong operation when one of the inputs is a floor.
1
Different
Three departments, three real answers
A neurological service works to the most conservative standard in this field. An orthopaedic one is restrained but ordinary. A sports department can be the most relaxed, because its population chose to be there and does not stay long.
Rule: and a shared foyer cannot deliver three of anything.
2
Not average
Halfway satisfies nobody
A level between a neuro standard and a sports standard is too high for the neuro patients and pointless for the sports ones. That is not a compromise between two positions - it is a failure of both.
Test: averaging is the wrong operation on these inputs.
3
A floor
A strict standard is a requirement, not a taste
The neuro department asking for a very low level is stating a requirement. The sports department is being permissive rather than demanding - it can tolerate more, but it does not need more.
Rule: which makes the two inputs different kinds of thing.
4
Free
The strictest standard costs the others nothing
No sports patient is disadvantaged by a quieter reception, and no orthopaedic patient is worse off. Only one department would be harmed by the reverse decision, and it is the one you are protecting.
Test: the asymmetry decides it without anybody negotiating.
5
Method
List them side by side and take the maximum
A neurological or stroke service almost always sets it, and frequently the answer is a neutral building throughout. One register, one level, one shared zone - Mountain Breeze at ₹849 on a SOSA Vaayu at ₹11,999.
Rule: and every treatment area in every department is never scented.
The SOSA principle
A strict standard is a floor; a relaxed one is a permission. Those are different kinds of thing, which is why you take the maximum rather than the average.
And the asymmetry settles the argument: adopting the strictest standard costs the looser departments nothing, while the reverse would harm the one department that actually had a requirement.
A multidisciplinary building, question by question
Why averaging fails, which department decides, and what it costs the others.
The SOSA rehabilitation table
What a multidisciplinary rehabilitation centre should smell like
| The question | The answer |
|---|---|
|
What sets the standard?
|
Whichever department has the strictest one. In shared air that requirement becomes the floor for the whole building. |
|
Why not average the departments?
|
Because a level halfway between a neuro standard and a sports standard is too high for one and pointless for the other - a failure of both rather than a compromise. |
|
Why does the strictest win?
|
Because a strict standard is a requirement while a relaxed one is a permission. The sports department can tolerate more but does not need more. |
|
What does that cost the other departments?
|
Nothing. No sports or orthopaedic patient is disadvantaged by a quieter reception, while the reverse decision would harm the one department with an actual requirement. |
|
What is the specification?
|
One register, one level, one shared front-of-house zone - Mountain Breeze (₹849) on a SOSA Vaayu (₹11,999), with every treatment area in every department unscented. |
The neuro standard is in whether a neuro centre should use fragrance, the sports exception in a sports injury and recovery clinic, and the departmental question in different policies per department. Fragrance is not a therapy and SOSA makes no claim that it contributes to recovery, mobility, pain, mood, motivation or attendance.
One register, the public zone only, set from the furthest chair
SOSA Vaayu ₹11,999 waterless, key-locked and timed to facility hours; Mountain Breeze ₹849 or Morning Freshness ₹749 as the register. Send the floor plan with the therapy areas marked and we will return it with the placement and the fragrance-free seating.
Adopting the strictest standard in the building costs every other department nothing at all. The reverse decision costs one of them a great deal.

 SOSA Boond
|
An admin cabin, counselling room or single desk | One small enclosed space only, on low; never placed in a therapy area, and never used to hold an open floor | ₹899 View → |
A SOSA Sukoon (₹1,899) is the water-based rung for a single enclosed reception or family waiting room of roughly 270-320 sq ft in a dry room, and a Boond (₹899) for an admin cabin or a single desk; both run on the water-based Hotel Collection fragrance (from ₹299), which is not reed diffuser oil and is not interchangeable with it. Above about 3,000 sq ft of one connected volume the step is one SOSA Angaan (₹25,999) on the duct, not a second Vaayu. Therapy and treatment areas are never scented - gyms and exercise floors, physiotherapy and occupational therapy areas, neuro-rehabilitation therapy rooms, hydrotherapy, treatment cubicles, post-operative and recovery areas and changing rooms - and that is achieved by placement and doors rather than by a lower setting. A named seating area away from the source is kept genuinely fragrance-free and offered by the desk rather than waiting to be asked, because patients here attend repeatedly over months. Fragrance is an ambience decision like lighting or seating: it does not remove or reduce anything in the air, it is not a therapy and makes no contribution to recovery, healing, mobility, pain, mood, motivation or adherence, and it works alongside ventilation, cleaning, laundry and infection control, never instead of them. The treating clinician's judgement overrides any plan. Ask for a facility scenting plan and send the floor plan with the therapy areas marked.
