By the length of time a person is in each room rather than by its floor area - because the model hall is five minutes on your feet, the lounge is forty minutes seated, and the closing room is the one place in the building where a buyer cannot ask for anything to be changed without paying for it at the table

By time in the room, not by floor area. The model hall is five minutes standing. The lounge is forty minutes seated. And the closing room is never scented - for a reason about the buyer, not the air.
Quick answers — read this first
What sets the level in an experience centre? How long a person stays in each room. A register that is right for someone passing through in five minutes is too much for someone seated in the same register for forty.

Why is the closing room never scented? Because a buyer mid-negotiation cannot ask for the room to be changed without spending something at the table. The ability to object is compromised, so consent is not really available.

Should the model hall be the loudest room? No, and most centres get this backwards. It is the biggest volume and the shortest stay, so it should be the quietest in delivered terms.
The short answer
Short answer: by time in the room rather than square feet - set the level from the longest seated stay, let the model hall read as almost nothing, and leave the closing rooms completely unscented.
The pick: an SOSA Angaan (₹25,999) on the supply serving the model hall and lounge, or a SOSA Vaayu (₹11,999) where they are one connected volume.
Next step: time a real buyer through each room with a stopwatch before you specify anything. Or ask for a scenting plan for your space.
Three rooms, three stay lengths, in five linesModel hall: five minutes, standing, movingLounge: thirty to forty minutes, seatedClosing room: an hour, door shut, two peopleSet the level from the longest stayAnd the closing room carries nothing at all
A buyer who is negotiating cannot ask you to change the room. That is why one room stays out of the plan.
Straight answer
How should a Kokapet developer scent a large experience centre with models, lounges and closing rooms?
Not room by room in the way most centres do it, which is by size - but room by room by how long a person actually stays in each one. An experience centre is three buildings pretending to be one. The model hall is the largest volume and the shortest visit: five to eight minutes, on your feet, walking around a table, looking down at a scale model with forty other people circulating. The lounge is a fraction of the volume and five times the visit: thirty or forty minutes seated, with coffee, going through floor plans. And the closing room is the smallest volume of all and the longest stay: forty-five minutes to an hour and a half behind a shut door, two or three people, papers on the table. Those three numbers matter far more than the square footage, because of one fact about the nose that owners rarely build around: perception of a constant smell falls away within the first several minutes of exposure and then keeps falling. A register set to be clearly noticeable in minute one is set wrong for minute thirty, and a register set to sit correctly at minute thirty will barely register in minute one. You cannot have both, so you have to choose which minute you are designing for - and the honest answer is that you design for the longest stay, because that is the person who has the most of it. Which reverses the instinct. The model hall is the room a centre wants to be impressive, so it is the room where output gets turned up - and it is precisely the room where that spend is wasted, because it is a large volume, people are moving through it, and they are gone before adaptation has even finished. The lounge is where the level is actually decided. Set it from the chair furthest from the machine, judged after somebody has sat in it for half an hour rather than after walking past it, and then accept that the model hall will read as very nearly nothing. Arrival is a separate lever and a stronger one. Then the closing room, and this is the part that is not about air at all. The general rule in this cluster is that closed one-to-one rooms are never scented, and a closing room is the clearest case of it I know. A buyer in that room is in the middle of the largest transaction of their life, across a table from somebody whose job is to conclude it. If the room bothers them, they will not say so - not because they are shy, but because raising any objection at that table costs them something, and a person who is about to ask for a discount on the corner unit does not spend one of their small number of requests on the smell of the room. The ability to object is structurally unavailable in there. Which means consent is not really available either, and a room where consent is not available does not get scented. Leave it out, keep it ventilated, and let it smell of nothing. The same room-by-room separation governs a hotel lobby against its restaurants. So the specification is one register, two rooms, one level, set from the lounge chair. An SOSA Angaan at ₹25,999 on the supply serving the model hall and lounge where they are genuinely large, or a SOSA Vaayu at ₹11,999 where they are one connected volume of ordinary size. Fragrance is an ambience decision like lighting or seating: it does not remove or reduce anything in the air, it treats nothing and relieves nothing, and SOSA makes no claim that it does. Closing rooms and every other closed one-to-one room are never scented. A named seat in the lounge, away from the source, is kept genuinely fragrance-free and offered rather than requested. It works alongside ventilation, cleaning and housekeeping, never instead of them, and the visitor's preference overrides any plan. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

What to buy, and for which space

The honest options for the visitor-facing zone, sized to the floor rather than to the ambition. The images link to the product pages so every figure here can be checked.

SOSA Angaan
One connected visitor-facing volume above about 3,000 sq ft, on the duct
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³ - roughly 8,000-10,000 sq ft - with an 800ml reservoir, a metal body, programmable schedules and operation under 42dB. Above about 3,000 sq ft of one connected visitor-facing volume this is the step rather than a second Vaayu, because two machines in one air mass drift apart. Critically, it goes on the supply side of the air handling that serves the visitor-facing zone only - never on a run that also feeds the treatment rooms or consultation cabins, which is the commonest way a zoning plan fails.
₹25,999
SOSA Vaayu
A connected reception, waiting area 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 clinic, salon or showroom its value is control rather than reach: the key-lock holds the level the furthest waiting chair was judged to, so it survives every shift and every new receptionist, and the 1h/4h/8h/24h timer keeps it on opening hours rather than saturating an empty room overnight. Waterless, so it adds no moisture and leaves no residue on stock, mirrors, screens or displays. 400ml tank, roughly 75-90 days depending on intensity and run hours, under 38dB, wall or HVAC mount.
From ₹11,999
SOSA Vaayu
The rung below the Angaan - one connected client floor, one machine
SOSA Vaayu Waterless Diffuser
1000m³ coverage (about 2,000-3,000 sq ft) on a single unit, ₹11,999. In a Hyderabad clinic, salon or showroom it is bought for the key-lock that holds the level the furthest seat chose, the 1h/4h/8h/24h timer that keeps it on opening hours, and a waterless output that adds no moisture in a humid month and leaves no residue on stock, mirrors or displays. Adjustable intensity, 400ml tank running roughly 75-90 days depending on intensity and run hours, Bluetooth app and onboard buttons, auto-stop, under 38dB, DC 12V/1A at 5W. Freestanding, wall or HVAC mount. CE, RoHS and SGS certified - electrical and compliance marks only. Made in India.

Three rooms, three stay lengths, one level

The floor areas are a distraction. What decides the setting is how many minutes a person spends breathing it.

1
Model hall
Biggest room, shortest stay
Five to eight minutes on your feet, circulating around a table with forty other people. The largest volume in the building and the one with the least time in it.
Rule: spend here buys the least.
2
Lounge
Where the level is decided
Thirty or forty minutes seated with coffee and floor plans. Judge it from the chair furthest from the machine, after half an hour in it rather than after walking past.
Test: design for minute thirty, not minute one.
3
Adaptation
You cannot have both minutes
Perception of a constant smell falls away within the first several minutes. A level that is clearly noticeable at minute one is wrong at minute thirty, and the reverse is equally true.
Rule: choose the minute you are designing for.
4
Closing room
Consent is not available in there
A buyer mid-negotiation will not spend one of their small number of requests on the smell of the room. The ability to object is compromised by the transaction itself.
Rule: so it is never scented, and stays ventilated.
5
The buy
One register, two rooms
An Angaan on the supply where the model hall and lounge are genuinely large, or a Vaayu where they are one connected volume of ordinary size.
Rule: one level, locked, set from the chair.
The SOSA principle
A buyer in a closing room will not tell you the room bothers them. Raising anything at that table costs them position, and nobody spends a request on the smell of a room when they are about to ask about the price.
Which is why that room is excluded on grounds of consent rather than on grounds of air, and why no level is low enough to make it acceptable.
SOSA Angaan
Above about 3,000 sq ft of one visitor-facing volume: SOSA Angaan, ₹25,999 - rated to 3,000m³, 800ml reservoir, programmable schedules, under 42dB. On the run that serves the visitor-facing zone only, never one that also feeds the dealing floor.

A large experience centre, question by question

Three stay lengths, one level, and the room that stays out of the plan.

The SOSA Hyderabad table
Models, lounges and closing rooms
The question The answer
What decides the level across the centre?
How long a person stays in each room. Set it from the longest seated stay, because that visitor has the most exposure to whatever you choose.
Should the model hall be the strongest room?
No. It is the biggest volume and the shortest visit, with people moving through it, so it should read as very nearly nothing in delivered terms.
Why can I not have it right in both rooms?
Because perception of a constant smell falls away within minutes. A level noticeable at minute one is wrong at minute thirty, and the reverse holds.
Why is the closing room excluded?
Because a buyer mid-negotiation cannot object without spending position at the table, so consent is structurally unavailable and the room stays unscented.
SOSA AngaanWhat is the specification?
One register across model hall and lounge - an Angaan (₹25,999) on the supply, or a Vaayu (₹11,999) for one connected volume.

The two-room version is sample apartment against sales lounge, the arrival version is the first ten seconds in a sales gallery, and the placement version is where the machine goes at drawing stage. SOSA makes no claim that fragrance affects what a buyer decides.

SOSA Vaayu
Below that line, and per separated zone: SOSA Vaayu, ₹11,999 - one per connected visitor-facing air mass, each set from its own furthest chair and key-locked; never two in one air mass sharing a guess.
One register, the visitor-facing zone only, set from the furthest seat
SOSA Vaayu ₹11,999 waterless, key-locked and timed to opening hours; Mountain Breeze ₹849 or Morning Freshness ₹749 as the register. Send the floor plan with the closed rooms and the entrance marked and we will return it with the placement and the fragrance-free seat.
See the SOSA Vaayu Book a scenting plan
Time each room with a stopwatch before you specify anything. Five minutes, forty minutes and ninety minutes are three different design problems wearing the same floor plan.

A SOSA Sukoon (₹1,899) is the water-based rung for a single enclosed reception or client lounge of roughly 270-320 sq ft in a dry room, and a Boond (₹899) for a single cabin; 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. Closed treatment rooms, consultation cabins and any closed one-to-one room are never scented - the person inside cannot leave and did not choose to be there - and that is achieved by placement and doors rather than by a lower setting. A named seat away from the source is kept genuinely fragrance-free and offered at the desk rather than waiting to be asked. Fragrance is an ambience decision like lighting or seating: it does not remove or reduce anything in the air, it treats nothing and relieves nothing, it makes no contribution to what a visitor buys, books or decides, and it works alongside ventilation, cleaning and housekeeping, never instead of them. The visitor's preference overrides any plan. Ask for a scenting plan for your space and send the floor plan with the closed rooms and the entrance marked.

A note from Sonal

Not room by room by size, which is how most centres do it, but room by room by how long a person actually stays. An experience centre is three buildings pretending to be one. The model hall is the largest volume and the shortest visit: five to eight minutes on your feet, walking around a table with forty other people circulating. The lounge is a fraction of that volume and five times the visit: thirty or forty minutes seated, with coffee and floor plans. The closing room is the smallest volume and the longest stay: forty-five minutes to an hour and a half behind a shut door.

Those three numbers matter far more than the square footage, because perception of a constant smell falls away within the first several minutes of exposure and keeps falling. A register set to be clearly noticeable in minute one is set wrong for minute thirty, and one that sits correctly at minute thirty will barely register in minute one. You cannot have both, so you choose which minute you are designing for - and you design for the longest stay, because that person has the most of it. That reverses the instinct. The model hall is the room a centre wants to be impressive, so it is where output gets turned up, and it is exactly where that spend is wasted: large volume, people moving, gone before adaptation has finished. The lounge is where the level is decided - from the chair furthest from the machine, judged after half an hour in it rather than after walking past.

Then the closing room, and this part is not about air at all. A buyer in that room is in the middle of the largest transaction of their life, across a table from somebody whose job is to conclude it. If the room bothers them they will not say so - not from shyness, but because raising anything at that table costs them something, and a person about to ask for a discount on the corner unit does not spend one of their few requests on the smell of the room.

Frequently asked questions

How should an experience centre be zoned for scent?
By how long a person stays in each room rather than by floor area. Model hall, lounge and closing room are three different problems on one floor plan.
Which room should set the level?
The lounge, judged from the chair furthest from the machine after half an hour of sitting in it, because that visitor has the most exposure.
Why will the model hall read as almost nothing?
Because it is the largest volume with the shortest visit and people are moving through it, so a level correct for a seated half hour barely registers.
Why are closing rooms never scented?
Because a buyer mid-negotiation cannot object without spending position at the table, which makes consent structurally unavailable in that room.
What equipment suits a large experience centre?
An Angaan on the supply serving the model hall and lounge, or a Vaayu where those two rooms are one connected volume of ordinary size.
SOSA Angaan
One duct, one level, the client zone only: SOSA Angaan, ₹25,999 - programmable schedules on the supply side of the air handling that serves reception and the waiting area, and nothing that reaches a dealing desk or a meeting-room door.
Time each room before you specify
SOSA — Studio Scenting minutes, not square feet
An experience centre is three stay lengths on one floor plan: five minutes standing in the model hall, forty minutes seated in the lounge, and an hour and a half behind a shut door in the closing room. Set one level from the lounge chair and accept that the model hall will read as almost nothing. The closing room is excluded outright, because a buyer mid-negotiation cannot ask for it to be changed. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the planning advice applies to any brand.

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 only. Being waterless it adds no moisture and leaves no residue on paper, screens or documents; 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. Ambient fragrance in a commercial space is an interior and hospitality decision only. SOSA makes no claim that it treats, relieves, prevents or improves any medical, dental or psychological condition, that it makes anyone feel calmer, more comfortable or more confident, that it affects recovery, patient comfort or any clinical outcome, or that it affects footfall, walk-ins, enquiries, bookings, conversions, sales, average spend, dwell time, customer retention or revenue. It does not remove or reduce any odour in the air, and it is never a substitute for ventilation, cleaning, housekeeping or fresh-air exchange - an office with a persistent smell has a source to find and fix first. Closed treatment rooms, consultation cabins and any closed one-to-one room are never scented, because the person inside cannot leave and did not choose to be there. A named seat away from the source is kept genuinely fragrance-free in the reception or waiting area and offered rather than waiting to be requested. The visitor's preference overrides any plan on this page, and where a customer, patient or member of staff is sensitive to fragrance the correct response is to reduce or switch off. 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.
