Nine inputs, but only three questions: may we scent here, how much air is there, and whose nose is in it. Then a fixed order of operations, the same at every branch.
Quick answers — read this first
What are the three questions the nine inputs answer? Whether the site may be scented at all (building age, new construction), how much air must be served (ceiling height, branch size, HVAC, heat), and whose nose is in it (locality, footfall, dwell time).
Which inputs can stop a branch being scented? Building age and new construction. An unresolved source or an interior still off-gassing is a gate, and no amount of favourable arithmetic on the other seven rows opens it.
What is the order of operations? Gate, then count air masses, then volume, then hardware, then the brand register, then the local level, then the key-lock, then the card, then a hot-season re-check.
The short answer
Short answer: sort the nine into three questions - may we scent here, how much air is there, and whose nose is in it - then apply a fixed order: gate, air masses, volume, hardware, register, level, lock, card.
The pick: by air mass: a SOSA Mountain Breeze (₹849) for one seating group, a SOSA Vaayu (₹11,999) per connected volume, an SOSA Angaan (₹25,999) above about 3,000 sq ft.
How should locality, building age, heat, HVAC, ceiling height, footfall, dwell time and branch size determine the scenting system at each Hyderabad branch?
Sort them before you use them, because nine inputs presented as a flat list is how a rollout becomes nine separate arguments at every new site.They only answer three questions, and the questions are asked in order.Question one: may this branch be scented at all?Two inputs answer it and both are gates rather than dials.Building age is a probability statement about sources.An older Hyderabad building is more likely to have a dry trap, a tired duct run, a damp riser or thirty years of carpet in it, and none of that is a fragrance question - so an old-building branch gets the overnight diagnostic before it gets a machine, and the source list is the starting point. New construction is the harder gate because it looks like the opposite of a problem.A brand-new fit-out is still emitting from paint, foam and board adhesive, and nothing goes in until a closed-night walk-in smells of nothing, which is the whole timing question for a new interior. Both of these are absolute: no amount of favourable arithmetic on the other seven rows opens a gate that is shut.Question two: how much air has to be served?Four inputs answer it, and the first thing to notice is that none of them is floor area on its own.Ceiling height multiplies volume without changing anything on the plan, so the section matters as much as the plan - and height is why fragrance appears to disappear upward. Branch size is counted in air masses rather than square feet: two rooms with a door between them are two problems, and one open 2,000 sq ft plate is one.HVAC decides residence time and also decides whether a duct-mounted option exists at all, because a supply run shared with closed rooms removes it permanently, which is why diffusion belongs on the HVAC drawing. And heat does two things at once: it raises consumption, so the same branch uses more in May than in December, and it raises perceived intensity, so a level set in January reads louder in April without anybody touching it.Question three: whose nose is in that air, and for how long?Three inputs answer it.Locality does not change the register - the register is a brand decision made once - but it changes what your room is heard against and therefore where the boundary has to be: a branch on a dense market street with a door to the pavement needs a vestibule or an entry run that a branch in a conditioned mall lobby does not.Footfall is really two things: bodies, which make the room warmer and more humid so a given output reads stronger, and door events, which are countable exchanges rather than a vague nuisance.And dwell time decides who the level belongs to.A branch where customers are in and out in six minutes is set for an arriving nose; a branch where somebody sits for ninety minutes is set for a nose that has fully adapted by minute ten and for staff who are there for nine hours, which means the ninety-minute branch always runs lower than instinct suggests.Now the order of operations, which is the part that makes a site sheet into a system.One: run the gates.If either is shut, stop, and put the money into the source or into time.Two: count the air masses by walking the floor, not by reading the plan, because air ignores the line where the flooring changes.Three: compute volume for each visitor-facing mass - floor area multiplied by ceiling height - and note the air-change rate from whoever maintains the system.Four: pick the hardware from that number and nothing else.Five: apply the brand register, unchanged, which is never a branch decision.Six: derive the level locally at the busiest hour from the furthest seat, by somebody who has been outside for ten minutes.Seven: key-lock it.Eight: write the card and file it in the branch handover pack.Nine: diary a re-check in the first hot month, because heat will have moved the answer.At a certain number of branches this stops being judgement and becomes an SOP, and whether every location should smell identical is the question underneath all of it. Hardware follows the volume honestly: a SOSA Mountain Breeze Reed Diffuser at ₹849 where reception is one seating group, a SOSA Sukoon at ₹1,899 for one enclosed room, a SOSA Vaayu at ₹11,999 per connected visitor-facing air mass, and an SOSA Angaan at ₹25,999 above about 3,000 sq ft of one connected volume, on the supply serving the visitor zone only.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.Closed treatment rooms and consultation cabins are never scented.A named seat 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.
Nine inputs, three questions. Building age and new construction are gates. Ceiling height, branch size, HVAC and heat size the air. Locality, footfall and dwell time name the nose. Then a fixed order: gate, air masses, volume, hardware, register, level, lock, card, hot-season re-check.
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.
One connected visitor-facing volume above about 3,000 sq ft, on the duct
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.
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.
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.
Two rows can stop the project. Four rows size it. Three rows decide who the level belongs to.
1
The gates
Building age and new construction
An older building gets the overnight diagnostic before it gets a machine. A new fit-out waits for a closed-night walk-in to smell of nothing. Neither is negotiable against the other rows.
Rule: a shut gate is not outvoted by seven dials.
2
The air
Height, size, HVAC, heat
Volume is plan multiplied by section. Size is counted in air masses, not square feet. HVAC sets residence time and whether a duct option exists. Heat raises both consumption and perceived intensity.
Test: no row here is floor area on its own.
3
The nose
Locality, footfall, dwell time
Locality changes the boundary rather than the register. Footfall means bodies and door events. Dwell time decides whether the level is set for an arriving nose or for one that adapted at minute ten.
Rule: the long-dwell branch always runs lower.
4
Order
Gate, count, compute, choose
Run the gates. Walk the floor and count air masses rather than reading the plan. Compute volume and get the air-change rate. Then pick hardware from that number and nothing else.
Rule: the order is what makes it a system.
5
Close out
Register, level, lock, card, re-check
The register is fixed brand-wide and is never a branch decision. The level is derived locally at the busiest hour from the furthest seat, locked, written on a card, and re-checked in the first hot month.
Test: file it in the handover pack.
The SOSA principle
Nine inputs, but they only ever answer three questions - may we scent here at all, how much air is there, and whose nose is in it. Everything else on a site sheet is bookkeeping.
Which is why the order matters more than the rows: a site sheet with no order of operations is a shopping list, and a shopping list is what produces nine arguments at every new location.
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.
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.
A shut gate is not outvoted by seven favourable dials. If the building has an unresolved source, or the fit-out is still emitting, there is no arithmetic on the other rows that makes a machine the right purchase.

Sized to the floor
The visitor zone gets one source; closed treatment and consultation rooms get none
One register, delivered at whatever size the visitor-facing zone is, with the rule that travels alongside each product. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
The SOSA Hyderabad specification
What goes where in a clinic, salon, showroom or office
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

Then the order of operations, which is what turns a site sheet into a system. Run the gates; if either is shut, stop and spend the money on the source or on time. Count the air masses by walking the floor rather than reading the plan, because air ignores the line where the flooring changes. Compute volume for each visitor-facing mass and get the air-change rate from whoever maintains the system. Pick the hardware from that number and nothing else. Apply the brand register unchanged, because that is never a branch decision. Derive the level locally at the busiest hour from the furthest seat, by somebody who has been outside for ten minutes. Key-lock it, write the card, file it in the handover pack, and diary a re-check in the first hot month. A SOSA Mountain Breeze Reed Diffuser at ₹849 where reception is one seating group, a SOSA Vaayu at ₹11,999 per connected visitor-facing air mass, an SOSA Angaan at ₹25,999 above about 3,000 sq ft of one volume.

Frequently asked questions
Which factors decide whether a branch can be scented at all?
Building age and new construction. An older building gets an overnight source diagnostic first, and a new fit-out waits until a closed-night walk-in smells of nothing.
Should machine size be chosen from floor area?
No. It is chosen from volume per air mass - floor area multiplied by ceiling height - with the air-change rate and the hot season taken into account.
Does the fragrance itself change from branch to branch?
No. The register is a brand decision made once for the whole business. What changes locally is the level, the placement and the boundary.
Why does customer dwell time change the setting?
Because it decides whose nose the level belongs to. A six-minute visit is judged on arrival; a ninety-minute stay is judged by a nose that adapted long before.
What is the order of operations for a new branch?
Gates, air masses, volume, hardware, brand register, local level, key-lock, written card, and a re-check in the first hot month of the year.
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.
Nine inputs answer three questions. Building age and new construction are gates that can stop a branch outright. Ceiling height, branch size, HVAC and heat size the air that has to be served, and none of them is floor area on its own. Locality, footfall and dwell time decide whose nose the level belongs to. Then apply them in a fixed order - gate, air masses, volume, hardware, register, level, lock, card, hot-season re-check - at every location.

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. Prices and availability are subject to change - see the live product pages.
