What gets crossed off, and in what order? Three passes, and the third is the one people skip. First cross off everything unbounded: the terrace, the courtyard, the roof, a frontage that folds open, a pergola with no walls. Second cross off everywhere people eat: the dining room, the chef's table, the bar top, a tasting room, a private room in service, a banquet hall during service. Third, cross off anything whose air moves towards those places, which you learn from a tissue at nose height, checked twice at different hours.
What is usually left, and what does it cost? Less than the drawing suggests, and that is the point. A 6,200 sq ft restaurant can be 1,400 sq ft of terrace that contributes nothing, 2,300 sq ft of unscented dining, 900 sq ft of kitchen and a 300 sq ft private room - leaving a 320 sq ft foyer, a 260 sq ft waiting lounge, 140 sq ft of corridor and a 110 sq ft washroom lobby. About 830 sq ft, or 231m³ at 3m, which one Vaayu at ₹11,999 covers running low - and if the tissue disqualifies the foyer, a ₹849 reed.

Facts verified 5 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 adjustable intensity, a 400ml refillable tank lasting 90+ days a fill depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB at 5W, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification, which are electrical and compliance marks and not medical approvals. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering roughly 270-320 sq ft and is supplied with three 15ml fragrances; the water-based Hotel Collection (₹299 / ₹999 / ₹1,799) is an ultrasonic fragrance and is not a refill for a waterless cold-air machine. SOSA reed diffusers are alcohol-free and phthalate-free, with 50ml lasting about 6-8 weeks and 130ml about 14-18 weeks. Cold-air refill oil for the Vaayu is not currently sold separately - the machine ships with 400ml included and further refills should be confirmed with SOSA. Warranty, annual maintenance, installation and bulk terms are not published and should be confirmed before ordering. Ambient scent is an interior and hospitality decision: it makes no clinical, therapeutic or wellbeing claim, it works alongside proper extraction, grease management, drainage, cleaning and air change and is never a substitute for any of them, it is never used to mask or remove another smell, and no claim is made that fragrance influences a guest's decision or any commercial outcome. Dining rooms, chef's tables, tasting-menu rooms and food-preparation areas are left unscented, no machine is placed where its output can reach a table or a pass, no fragrance is described as food-safe or safe for use around food, and the operator's own kitchen consultant and local food-safety and fire authority govern anything sited near a kitchen. Fragrance oil is flammable and is kept away from open flame and heat. The chef's judgement overrides any scenting plan in their own room. 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.
Every zoning conversation I have with a restaurant starts with a drawing and ends with a roll of tape. A floor plan shows you where the architect put the walls; it does not show you where the air stops, and fragrance only obeys the second of those. This is the method I use to find out, and it is the same method whether your building is a terrace with a lobby or a courtyard with a gallery.
Quick answers — read this first
How should restaurants with indoor and outdoor sections approach scent zoning? By finding the air boundaries and ignoring the drawing. A zone is a volume of air, and a volume needs edges that air respects - a door that closes during service, a wall that goes to the ceiling, a change in air handling. A wide opening, a floor-finish change, a level change and a lowered ceiling are all zoning devices for the eye and none of them for air. So walk the building, mark the real edges on the floor with tape, and treat the taped plan as the only plan that matters.What gets crossed off, and in what order? Three passes, and the third is the one people skip. First cross off everything unbounded: the terrace, the courtyard, the roof, a frontage that folds open, a pergola with no walls. Second cross off everywhere people eat: the dining room, the chef's table, the bar top, a tasting room, a private room in service, a banquet hall during service. Third, cross off anything whose air moves towards those places, which you learn from a tissue at nose height, checked twice at different hours.

About 830 sq ft, or 231m³ at 3m, which one Vaayu at ₹11,999 covers running low - and if the tissue disqualifies the foyer, a ₹849 reed.
The short answer
Short answer: by air boundaries rather than by floor-plan lines. Walk the building with tape and a strip of tissue, mark where the air genuinely stops, and then cross off in three passes: everything unbounded, everywhere people eat, and everything whose air moves towards a place where people eat. What survives is the scented envelope. Measure it in cubic metres, count how many separate volumes it is, and buy the smallest source that holds a level in each.
The pick: one SOSA Vaayu (₹11,999) per bounded non-dining volume once that volume passes about 750 sq ft, wall or duct mounted so the output stays inside its boundary - or a SOSA Sukoon (₹1,899) for a volume of 300 to 750 sq ft, and a Mountain Breeze reed (₹849) for a single small room.
Next step: walk the building during service with a roll of low-tack tape and a strip of tissue, mark every real air boundary on the floor and the direction at each threshold, photograph the marks and send them with your floor plan - we will send back a zone list, a cubic figure per zone and the machine count, including the zones we would refuse - Ask for a restaurant scenting plan.

This is the family pillar, so it is a method rather than an opinion. Run the three passes honestly and the machine count falls out of the answer instead of being chosen first.

Straight answer
How should restaurants with indoor and outdoor sections approach scent zoning?
By deciding zones on air boundaries and ignoring the floor plan, which is the single most useful sentence in this family. A zone is a volume of air. A volume needs an edge that air respects - a door that is actually closed during service, a wall that runs to the ceiling, or a change in air handling with its own supply and return. Everything else designers use to divide a space is a zoning device for the eye: a wide opening, a change from timber to stone, a step up, a dropped ceiling. Air walks straight through all of them. So the exercise is physical. Take a roll of low-tack tape and a strip of tissue through the building during service and mark the real edges on the floor, then note which way the tissue leans at every threshold, twice - early and at the busiest hour, because a kitchen's extract is the strongest air mover in the building. Then run three passes. Pass one: cross off everything unbounded. The terrace, the courtyard, the roof, the section behind a frontage that folds open, a pergola with no walls. Ambient scenting needs bounded air and these have none. Pass two: cross off everywhere people eat. The dining room, the chef's table, any tasting-menu room, the bar top, a private room in service, a banquet hall while food is served, any canapé table. The dish on the plate is the composition your guest paid for, and no machine goes anywhere its output can reach a table. Pass three, the one nearly everybody skips: cross off anything whose air moves towards the rooms you crossed off in pass two. A foyer that vents towards the dining room is a dining-room position wearing a foyer's name, and the dial cannot rescue it. What survives is your envelope, and two numbers now matter: its volume in cubic metres, and how many separate volumes it is, because a machine belongs to a volume rather than a floor. The worked example I use: a 6,200 sq ft restaurant with 1,400 sq ft of terrace contributing nothing, 2,300 sq ft of unscented dining, 900 sq ft of kitchen, and a 300 sq ft private room unscented in service, leaving a 320 sq ft foyer, a 260 sq ft waiting lounge, 140 sq ft of corridor and a 110 sq ft washroom lobby. That is 830 sq ft, about 77m², so roughly 231m³ at 3m, and if the tissue shows they are one connected volume it is one SOSA Vaayu at ₹11,999 running well below its 1000m³ rating. If the tissue disqualifies the foyer, you are left with a washroom lobby and the honest answer is an ₹849 Mountain Breeze reed or a Sukoon at ₹1,899, and a Vaayu would be the wrong buy. The standing limits: ambience decision like lighting, never a mask, every dining zone stays unscented, and your chef's judgement overrides this plan in their own room. Ask for a restaurant scenting plan and send photographs of the tape.
Zone by air, not by drawing. Walk the building with tape and tissue, cross off everything unbounded, everywhere people eat, and everything whose air heads towards a table. Measure what survives in cubic metres and count the volumes - one machine per volume. Often that is 830 sq ft and one ₹11,999 machine, and sometimes it is one ₹849 reed.
Per bounded non-dining volume past about 750 sq ft, the machine is one SOSA Vaayu - 1000m³, waterless, under 38dB, with app timers, a key-lock and wall or duct mounting that keeps output inside the boundary. ₹11,999. For a volume of 300 to 750 sq ft, a Sukoon at ₹1,899 instead.

The rule this whole family turns on
A zone is a volume of air, and air does not read a floor plan
The machine, one per volume of air
Two honest answers, and the zone list decides both which one and how many. A second machine belongs to a second volume of air - a separate floor, a banqueting foyer with its own AC, a washroom lobby off a different corridor - and never to a second corner of the same room. The images link to the product pages.

SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³, about 2,000-3,000 sq ft, so an 830 sq ft envelope at 3m uses about a quarter of it. 400ml tank, 90+ days a fill, app timers, adjustable intensity, under 38dB, 5W, key-lock, and wall or HVAC mounting - the only reliable way to hold output inside a boundary. ₹11,999.

SOSA Sukoon
Ultrasonic cool-mist diffuser covering roughly 270-320 sq ft, supplied with three 15ml fragrances. Where the zone walk leaves you one small enclosed room - and in indoor-outdoor buildings it very often does - this is the right buy and a Vaayu at six times the price would be the wrong one. ₹1,899.

The three passes that build the zone list
Run these in order and do not reorder them, because each pass removes candidates the next one would otherwise waste your time on. The whole walk takes about forty minutes and needs a roll of tape, a tissue and a tape measure.
1
Pass one: cross off the unbounded
No edges means no volume, and no volume means no level
Walk out to every open part of the building and write it off before you think about anything else: the terrace, the courtyard, the roof deck, the section behind a frontage that folds open, a pergola or cabana with no walls that close. Ambient scenting needs bounded air, because what reads as a level is a balance between what a source releases and how fast the volume exchanges with somewhere else - and these spaces exchange with the sky. Then find the edge properly rather than assuming it: walk in from the open side with the back of your hand at shoulder height and feel where the conditioned air gives out, and put tape on the floor there. In most of these buildings the real edge is two to four metres inside the frontage.
Tip: Do pass one on a windy evening. A still evening flatters the building and gives you an edge that is not there tomorrow.
2
Pass two: cross off everywhere people eat
Dining is an exclusion, not a level to be tuned
Cross off the dining room, the chef's table, any tasting-menu room, the bar counter and its stools, a private dining room while guests are seated, a banquet hall whenever food is served in it, and any canapé or welcome-drink station in a foyer. These are not zones running at a lower setting; they are excluded, and the reason is that a seated guest cannot walk away from anything in the air for two or three hours, while the dish in front of them is the composition they paid for. No machine goes anywhere its output can reach a table, and if the only mounting position your building offers does, the honest answer for that building is to scent nothing at all.
Tip: Mark the exclusions on the plan in pen before anybody quotes you, and take a photograph of it.
3
Pass three: cross off everything upstream
A foyer that vents towards the tables is a dining-room position with a foyer's name
This is the pass that decides whether you buy anything, and it is the one almost everybody skips. Hold a strip of tissue at nose height at every surviving threshold during service and watch which way it leans, then repeat it at the busiest hour, because the kitchen's extract is the strongest air mover in the building and it pulls harder as the line comes on. Any volume whose air moves towards a room you crossed off in pass two is out of the plan, whatever the drawing says and whatever level you were planning to run. A kitchen at negative pressure will happily drag a foyer's fragrance across a chef's table on its way to the hood. Nothing we sell covers, removes or cancels a smell, and no dial fixes a direction.
One Mountain Breeze reed diffuser ₹849, set once and left alone, is the whole hardware side of this.

The SOSA principle
Zones are drawn by air rather than by architecture, so the plan you buy to is the one you get with a roll of tape and a strip of tissue, not the one the designer issued.
Run the three passes honestly and the machine count falls out of the building instead of being decided in a showroom.
The plan, as a walk you can do tonight
Here is the whole method as six steps, in the order to do them, with a tape measure at the end rather than the beginning.
The SOSA plan
Scent zoning an indoor-outdoor restaurant, step by step
| The step | What to do |
|---|---|
|
1. Redraw the building as volumes
|
Ignore rooms and list bodies of air instead, each one bounded by a door that closes in service, a wall to the ceiling, or its own supply and return. Wide openings, level changes and floor finishes create no boundary at all. |
|
2. Find the real edges on foot
|
Walk in from every open side with the back of your hand at shoulder height, feel where the conditioned air gives out, and put tape on the floor. Repeat on a windy evening, and treat the strip between the two marks as open air. |
|
3. Cross off the unbounded and the eating
|
Terrace, courtyard, roof and folded-open frontage in one pass; dining room, chef's table, bar top, private room in service, banquet hall during food and any canapé table in the next. |
|
4. Test every surviving threshold
|
Tissue at nose height, twice, early and at the busiest hour. Anything whose air heads towards an eating zone comes off the list. This is the step that decides whether you buy at all. |
|
5. Measure what is left, cubically
|
Floor area times ceiling height, volume by volume, and count how many separate volumes there are - a machine belongs to a volume, not a floor. 830 sq ft at 3m is about 231m³. |
|
6. Buy the smallest source per volume, then write it down
|
One source per body of air, at the lowest level that reads on the way out, with position, level, hours and who may touch it recorded and the key-lock on. |
The two hardest cases in this family are worth reading as worked examples of the method: whether an outdoor fine-dining restaurant should use a scent machine, where pass one removes the entire building and we sell nothing, and whether professional scenting works in a semi-open restaurant, where the whole job is finding the edge and accepting a gradient rather than a line. SOSA is independent and not affiliated with any hotel.
One volume, one source, one written setting
SOSA Vaayu ₹11,999 is rated to 1000m³ - about four times an 830 sq ft envelope at 3m, which is exactly why it runs low and stays inside its boundary.
I have never once specified a restaurant from its floor plan alone, and the reason is simple: a drawing shows where a designer wanted a room to end, and fragrance only cares where the air does.
— Sonal Sahani, SOSA
Why the boring specifications carry a zoning plan
A mount that holds a line, a timer per zone, and a lock per building
The SOSA zoning specification
Four products cover every zone list this method produces, and which one applies is decided by the cubic volume of each surviving body of air rather than by the size of the restaurant. Cold-air refill oil for the Vaayu is not currently sold separately, so the 400ml supplied runs 90+ days a fill and further supply should be confirmed with SOSA in writing before you plan a rollout around it.

Run the three passes before you price anything, measure cubically, and buy one source per body of air rather than one per floor. Ambient scent here is an ambience decision like lighting; it is never a mask for cooking, grease, smoke, a drain or a bin store; and every dining zone - the dining room, the chef's table, tasting rooms, the bar top, a private room in service and a banquet hall during food - stays unscented, with no machine placed where its output can reach a table. I will not describe any fragrance as food-safe or safe for use around food, because we have not tested for that and will not imply it, and anything sited near a food-preparation area is a question for your kitchen consultant and your local authority rather than for me. Fragrance oil is flammable and both oil and machine are kept away from open flame and heat, which across these buildings means patio heaters, table candles, tandoors, a bar torch and open ranges. And plainly: SOSA does not publish a business-outcome number because it has not measured one. Ask for a restaurant scenting plan before you spend anything.

A note from Sonal
The question I am sent is almost always which zones should be scented, and it arrives as a PDF of a floor plan with the rooms labelled. I have learned to answer it by asking for something nobody expects to be asked for: photographs of tape stuck to their own floor. A drawing tells me where a designer decided a room should end. It tells me nothing about whether air stops there, and fragrance only obeys the second thing. In an indoor-outdoor restaurant the gap between those two facts is often three or four metres, and everything in a scenting plan hangs on it.
So the method is three passes and it is deliberately unglamorous. Cross off everything unbounded, because a level is an equilibrium and open air has no equilibrium. Cross off everywhere people eat, because a seated guest cannot leave the air and the plate in front of them is the composition they paid for. Then cross off everything whose air moves towards the rooms you just excluded, which is the pass almost everybody skips and the one that decides whether there is anything to sell. A kitchen at negative pressure will pull a foyer's fragrance across a chef's table on its way to the hood, and a dial does not change a direction.
What is left is usually small, and that is the honest finding of this whole family. A 6,200 sq ft restaurant with a terrace commonly leaves 830 sq ft of bounded non-dining air - about 231 cubic metres at 3m - which is one Vaayu at ₹11,999 running at a quarter of its rating. A surviving volume of 300 to 750 sq ft is a Sukoon at ₹1,899. One small room is a Mountain Breeze reed at ₹849, and a very large banquet foyer is an Aangan at ₹25,999. And if the three passes leave you nothing, that is a real result and I will write it in an email. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How should restaurants with indoor and outdoor sections approach scent zoning?
By air boundaries, not by floor-plan lines. A zone is a volume of air, and a volume needs an edge air respects: a door closed during service, a wall to the ceiling, or its own supply and return. Wide openings, level changes, dropped ceilings and floor finishes divide a space for the eye and not for air. Walk the building with tape and a tissue, mark the real edges, and treat the taped plan as the only plan.
Which zones get crossed off, and in what order?
Three passes. First everything unbounded - terrace, courtyard, roof, a frontage that folds open, a pergola with no walls - because ambient scenting needs bounded air. Second everywhere people eat: dining room, chef's table, tasting room, bar top, a private room in service, a banquet hall during food, any canapé table. Third, anything whose air moves towards those places, which a strip of tissue at nose height tells you in two minutes.
Why does the direction of airflow matter so much?
Because a position is judged by where its output arrives, not by where the box stands. A foyer that vents towards the dining room is a dining-room position wearing a foyer's name, and lowering the level does not change the direction. A kitchen held at negative pressure, which is correct engineering, will pull corridor and foyer air through a counter or a pass on its way to the hood. Check twice, early and at the busiest hour, because the pull grows as the line comes on.
How many machines does a zoned restaurant need?
One per surviving body of air, never one per floor and never two in one room. A second machine belongs to a genuinely separate volume - another floor, a banquet foyer with its own air handling, a washroom lobby off a different corridor. Two units in one foyer do not give you a better level, they give you a hot spot and a shorter refill interval. The count comes out of the zone list rather than out of the square footage.
What does zoning usually cost once the passes are done?
Less than the floor plan suggests. A 6,200 sq ft restaurant can be 1,400 sq ft of terrace contributing nothing, 2,300 sq ft of unscented dining, 900 sq ft of kitchen and a 300 sq ft private room, leaving about 830 sq ft - roughly 231 cubic metres at 3m - which is one Vaayu at Rs 11,999 running low. If the third pass disqualifies the foyer, it is a reed at Rs 849 or a Sukoon at Rs 1,899 and a Vaayu would be the wrong buy.
