Should reception, treatment rooms and the rehab floor have different scents? No - one scent, run at three intensities: highest at reception, lowest in treatment rooms, lowest or nil on an open rehab floor that needs ventilation more than fragrance.
What happens above 3,000 sq ft? The honest next step is one SOSA Angaan at ₹25,999, not a second Vaayu.
Start with mounting, because it decides more than the product spec sheet does. A freestanding unit near reception works well in a compact, roughly rectangular layout where the corridor is short and straight - the machine's own output reaches the far end without help. Once the centre has a turn, a second wing, or the rehab floor sits at a distance from reception, a wall-mounted position mid-corridor, roughly a metre high and clear of both the AC draught and foot traffic, generally reaches both directions better than a single freestanding point can. Where the centre already has HVAC installed, mounting through the duct network moves distribution into the existing air-handling system entirely - a decision for the facilities engineer, not a fragrance one, and worth raising with them before finalising placement.
The scent itself does not change by area - it is one register throughout, run at different intensities by zone, which is the pillar this cluster returns to for every combined centre. Reception gets the highest setting, because it is where people arrive and wait. Manual-therapy treatment rooms get the lowest active setting, or nothing of their own beyond an inherited trace, because proximity and duration make that room the one place a strong dose is genuinely counterproductive. The open rehab or exercise floor gets the lowest setting or none at all - not because it matters less to the centre, but because exertion and air exchange on that floor mean ventilation is doing more useful work than fragrance ever could, and a stronger dose there would only compete with air the room needs moving, not held in place by scent.
One machine can genuinely serve all three areas if they behave as one connected volume of air - the test is whether you can see from one area to another with the doors as they normally sit, not whether they are labelled as separate zones on the floor plan. If reception, the treatment corridor and the rehab floor are open to each other or connected by a corridor with doors that are usually propped, one correctly mounted Vaayu reaches all three, adjusted for intensity by distance and airflow rather than by a second machine. If the rehab floor is genuinely a separate wing behind its own doors, treat it as its own volume of air and revisit whether it needs anything at all - many rehab floors are honestly better served by ventilation alone.
Above roughly 3,000 sq ft of connected air, the honest next step is one SOSA Angaan at ₹25,999, not a second Vaayu - stacking two machines in one connected volume creates competing gradients rather than combined coverage, which is worked through fully in one scent machine or multiple fragrance zones for a large clinic. Ask for a clinic scenting plan and send your layout; we will recommend a mounting point rather than just a product.
What a 2,000+ sq ft centre actually buys
One machine, correctly specified, with the mounting decision doing most of the remaining work.
The three things placement has to solve
At this size the product decision is settled. Placement is where the real work happens.
The scent map by zone and intensity
One register throughout. What changes zone to zone is the setting, never the scent.
| Zone | Target intensity | Why |
|---|---|---|
| Reception and entrance | Highest | Where people arrive and wait - the clinic's introduction. |
| Corridor and circulation | Medium, carrying the trace between zones | The shared air every area borders. |
| Manual-therapy treatment rooms | Lowest, or an inherited trace only | Proximity and duration - the practitioner's call, argued both ways elsewhere. |
| Open rehab or exercise floor | Lowest or nil | Exertion and air exchange mean ventilation matters more than fragrance here. |
Zoning by intensity across osteopathy, physio and rehab in general - including who decides the level - is worked through in how should a multi-practitioner musculoskeletal clinic approach ambient fragrance, and what happens if a second machine is added to fix a weak corner is covered in one scent machine or multiple fragrance zones for a large clinic. SOSA makes no claim that scenting affects bookings, retention or spend.

Versailles
A combined osteopathy and rehab centre once installed their Vaayu freestanding, right by the entrance, on the same day their fit-out finished - the obvious spot, since that's where the delivery box happened to land. Three weeks later they wrote to say the rehab floor at the back, past a turn in the corridor, wasn't getting anything at all.
We didn't recommend a second machine. We recommended moving the one they had to a wall-mounted position mid-corridor, past the turn, about a metre up. The rehab floor started picking up the same faint trace as everywhere else within a week, and reception - if anything - read slightly more consistent than before, because the unit was now working the whole floor rather than just the entrance it happened to be dropped near.
Fragrance is an ambience decision, like lighting or seating. It sits alongside your cleaning, laundry and ventilation and never replaces them. Whether a treatment room is scented at all is yours to decide, and if a client asks you to turn it off, turn it off.

Frequently asked questions
Facts verified 5 September 2026 against the live SOSA product pages: the SOSA reed diffusers are alcohol-free, phthalate-free and paraben-free compositions on a heat-stable coconut-derived base, supplied in a refillable glass bottle with six fibre reeds, flipped weekly, with 50ml lasting 6-8 weeks and 130ml lasting 14-18 weeks, tested at 45°C and 85% relative humidity - Morning Freshness ₹749 / ₹1,249, Mountain Breeze ₹849 / ₹1,349. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering about 270-320 sq ft for 16-18 hours on the low setting and supplied with three 15ml Hotel Collection fragrances; being ultrasonic, it works by aerosolising water and therefore adds some moisture to the air. 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 up to about 75 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 - which are electrical and compliance marks, not medical approval. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment; refill availability 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 and operation under 42dB. SOSA products are not medical devices and no health, therapeutic or wellbeing claim is made or implied anywhere in this guide; ambient scent is an interior and hospitality decision that works alongside cleaning, laundry, ventilation and hygiene protocol and is never a substitute for any of them. Infection control, linen protocol and HVAC standards are matters for the practitioner and the facilities engineer. Fragrance sensitivity is real: staff should be able to switch any system off in seconds, and no SOSA product is described as hypoallergenic or as safe for sensitive individuals. 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.
