Why cubic metres and not square feet? Because a nebuliser fills a room, not a plan. The Vaayu is rated to 1000m³ and the Angaan to 3,000m³; the square-foot figures on the box assume a normal ceiling. A 3,000 sq ft floor at three metres holds about 840m³ - one Vaayu - and the same floor at four metres holds about 1,100m³, past the Vaayu and into the Angaan. The ceiling is the only number on a plan that changes the machine, and it is the number nobody sends.
Do I subtract the demo kitchen from the area? From the scented map, always; from the volume, only if it is a closed room. An open live kitchen or coffee counter shares the floor's air, so it counts toward the cubic metres the machine must fill, but it stays unscented while it runs - the machine sits on the reception side, off on the schedule during every demonstration, with extraction running. A demo room behind its own door and extraction is its own volume, and it gets nothing. Fragrance is an interiors decision like lighting or music - SOSA makes no claim that it changes dwell time, footfall or sales.

Facts verified 7 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 90+ days a fill 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 - electrical and compliance marks. Being waterless, it adds no moisture and leaves no residue on surfaces or displays; the four 100ml bottles in the box are the supply, and 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, metal body, programmable schedules and operation under 42dB; the SOSA Meenar (₹38,500) is the HVAC machine for 12,000-18,000 sq ft. The SOSA Sukoon (₹1,899) is a 500ml water-based ultrasonic diffuser for a single room of roughly 270-320 sq ft. SOSA reed diffusers - Mountain Breeze (₹849 / ₹1,349) and Morning Freshness (₹749 / ₹1,249), 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 showroom is an interior and hospitality decision: SOSA makes no claim that it changes dwell time, footfall, conversion, basket size, sales or any other business number, no claim about what it does to any appliance, surface or finish on display, and it is never a substitute for ventilation, cleaning or extraction. Warranty, installation, service and bulk terms are confirmed with SOSA directly.

Most of the sizing questions I am sent arrive as a single number - eight thousand square feet, twelve thousand, what do I need - and the honest reply is that a single number cannot be sized. A scent machine is rated to a volume of air, a large store is usually several volumes, and the calculation is five steps of arithmetic that anyone with a tape measure and the air-conditioning drawing can do in an afternoon.
Quick answers — read this first
How do I calculate scent-machine requirements for a large appliance store? In five steps. Count the separate volumes of air - each floor with a solid slab between it and the next, each zone on its own air-handling unit, each closed room behind a door that stays shut. Measure the ceiling height in each and convert the area to cubic metres: square feet times 0.093 times metres of height. Match each volume to one rung of the ladder - a reed under about 300 sq ft, a SOSA Sukoon (Rs 1,899) at 300-750, a SOSA Vaayu (Rs 11,999) up to 1000m³, a SOSA Angaan (Rs 25,999) up to 3,000m³, a SOSA Meenar (Rs 38,500) for a 12,000-18,000 sq ft class of floor. Take the live kitchen and coffee counter off the scented map. Then check that no volume has two machines.Why cubic metres and not square feet? Because a nebuliser fills a room, not a plan. The Vaayu is rated to 1000m³ and the Angaan to 3,000m³; the square-foot figures on the box assume a normal ceiling. A 3,000 sq ft floor at three metres holds about 840m³ - one Vaayu - and the same floor at four metres holds about 1,100m³, past the Vaayu and into the Angaan. The ceiling is the only number on a plan that changes the machine, and it is the number nobody sends.
Do I subtract the demo kitchen from the area? From the scented map, always; from the volume, only if it is a closed room. An open live kitchen or coffee counter shares the floor's air, so it counts toward the cubic metres the machine must fill, but it stays unscented while it runs - the machine sits on the reception side, off on the schedule during every demonstration, with extraction running. A demo room behind its own door and extraction is its own volume, and it gets nothing. Fragrance is an interiors decision like lighting or music - SOSA makes no claim that it changes dwell time, footfall or sales.
The short answer
Short answer: count the volumes of air (floors, AC zones, closed rooms), measure the ceiling and convert each volume to cubic metres, give each volume one rung of the ladder, take the demo kitchen and coffee counter off the scented map, and check that no volume carries two machines. Never divide a floor area by a coverage figure and round up.
The pick: one SOSA Vaayu (₹11,999) for each volume up to 1000m³ - roughly 1,500-3,000 sq ft at a normal ceiling; one SOSA Angaan (₹25,999) for each volume up to 3,000m³ - roughly 3,000-10,000 sq ft; one SOSA Meenar (₹38,500) for a floor in the 12,000-18,000 sq ft class; a Sukoon (₹1,899) or a reed for any closed room too small for a machine.
Next step: send the floor plan, the ceiling heights and the AC zoning and we will run the five steps for you and name one machine per volume - ask for a showroom scenting plan.

Straight answer
How do I calculate scent-machine requirements for a large appliance store?
With five steps, in this order, and the first one is not the floor area. Step one: count the volumes of air. A machine scents the air it is in, and air stops at a slab, at the boundary of an air-handling zone, and at a door that stays shut. So walk the building with the air-conditioning drawing and count: each floor with a solid floor between it and the next is one volume; each zone served by its own air-handling unit is one volume; each closed room - a designer studio, a home-theatre demo room, a coffee lounge behind glass - is one volume. A mezzanine open to the floor below is part of that floor. A partition wall between display kitchens is not a boundary; it is a height problem, and the partition page deals with it. A large store usually comes out at two, three or four volumes, and that number is the machine count before you have looked at a single price. Step two: measure the ceiling in each volume and convert to cubic metres. Square feet times 0.093 gives square metres; times the ceiling height in metres gives cubic metres. A 6,000 sq ft floor at four metres is about 2,230m³; a 2,500 sq ft first floor at three metres is about 700m³; a 350 sq ft closed studio is under 100m³. If the ceiling steps, measure each part and add them. Step three: give each volume one rung of the ladder. Under about 300 sq ft, one Mountain Breeze reed (₹849). From 300 to 750, one Sukoon (₹1,899), water-based, said plainly. Between 750 and 1,500, a Vaayu is bought for its timer, key-lock, dry air and one-source reach, never for coverage. Up to 1000m³ - about 1,500 to 3,000 sq ft at a normal ceiling - one SOSA Vaayu at ₹11,999. Up to 3,000m³ - about 3,000 to 10,000 sq ft - one SOSA Angaan at ₹25,999, on the plant where there is one. For a floor in the 12,000 to 18,000 sq ft class, or a 10,000 sq ft floor whose ceiling has carried it past 3,000m³, one SOSA Meenar at ₹38,500. Step four: take the demonstration off the map. The live kitchen, the hob and oven demo and the coffee-tasting counter stay unscented while they run - that is the rule the whole cluster is built on - and they come off the scented map, not off the count. An open demo kitchen shares the floor's air, so its cubic metres are still in the sum; the machine simply sits on the reception side, goes off on the schedule for every demonstration, and extraction does the clearing. A demo room behind its own door and its own extraction is a volume in its own right, and its machine count is zero. Step five: check the count. Every volume has exactly one machine, sized to its own cubic metres, and no volume has two. A floor that has outgrown a Vaayu takes an Angaan; one that has outgrown an Angaan takes a Meenar - never two of the smaller machine in the same air, because two sources in one volume make a band in the middle and two dials that drift; one large machine vs several small explains why. What this sum is not is a business case. Fragrance is an interiors decision, like lighting or music: SOSA makes no claim that it changes footfall, dwell time, conversion or sales, no claim about what it does to any appliance or finish on display, and it is never a substitute for ventilation, cleaning or extraction. Ask for a showroom scenting plan and we will run the five steps on your drawing.
Count the volumes of air (floors, AC zones, closed rooms); convert each to cubic metres (sq ft x 0.093 x ceiling metres); one rung per volume - Vaayu (Rs 11,999) to 1000m³, Angaan (Rs 25,999) to 3,000m³, Meenar (Rs 38,500) for 12,000-18,000 sq ft; demo kitchen and coffee counter off the map; never two machines in one air.
For any single volume between 1000m³ and 3,000m³ - about 3,000-10,000 sq ft at a normal ceiling - one SOSA Angaan, HVAC-connected or standalone, at ₹25,999. One volume, one machine.

Each machine is rated to a volume of air - the plan tells you which rung only once you know the ceiling
The ladder, rung by rung
The two rungs a large store lands on most often, each described for the volume it is honest for. The images link to the product pages so every figure here can be checked directly.
One volume of 1000-3,000m³ - a connected floor of about 3,000-10,000 sq ft
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³ - the manufacturer's figure is 8,000-10,000 sq ft at a normal ceiling. 800ml reservoir, metal body, programmable schedules so demo windows are cut out, under 42dB. Connects to an air-handling duct that serves the sales floor alone, or wall-mounts standalone. The rung for a main floor that has passed a Vaayu's 1000m³, and the one to step up to rather than doubling a Vaayu. Rs 25,999.
₹25,999
One volume up to 1000m³ - a connected floor of about 1,500-3,000 sq ft, or a wing on its own AHU
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft at a normal ceiling. 400ml tank, 90+ days a fill; 1h/4h/8h/24h timer; adjustable intensity; key-lock; under 38dB; wall or HVAC mount. The rung for a first floor, a separately air-conditioned wing or a mid-sized main floor - and the machine most often wrongly doubled. Rs 11,999.
From ₹11,999
The five steps of the calculation
Each step in the order it has to be taken, with the arithmetic written out. Do them on paper before anyone opens a catalogue; the catalogue is only used in step three.
1
Step one
Count the volumes of air, not the rooms and not the floor area
Air is what gets scented, and air is divided by three things: a solid slab, the boundary of an air-handling zone, and a door that stays shut. Take the air-conditioning drawing - or, if there is none, walk the building and note which grilles belong to which unit - and count. A ground floor and a first floor with a slab between them are two volumes even if a stair connects them. A wing on its own air-handling unit behind doors that close is a volume of its own, even on the same floor. A closed designer studio, a home-theatre demo room and a glazed coffee lounge are each one volume, however small. What is not a boundary: an open mezzanine, a partition between display kitchens, a change of flooring, a run of tall units. The 7,500 sq ft page is the one-volume-or-two test in full and the two-floor page is the commonest split; both come down to the same question - does this air mix with that air? The count you finish with is the number of machines, before any of them has a name.
Test: stand at the far end of what you think is one volume with the AC running. If you had to open a door that stays shut, or climb past a slab, to get there, you are in a second volume.
2
Step two
Measure the ceiling and turn every volume into cubic metres
A machine is rated to cubic metres - the Vaayu to 1000m³, the Angaan to 3,000m³ - and the square-foot figures on the box are those ratings divided by a normal ceiling. So the sum is: square feet, times 0.093 to get square metres, times the ceiling height in metres. At three metres, 1,000 sq ft is about 280m³, 3,000 sq ft about 840m³, 5,000 sq ft about 1,400m³ and 10,000 sq ft about 2,800m³. Raise the ceiling to four metres and each of those grows by a third: the 3,000 sq ft floor becomes about 1,100m³ and leaves the Vaayu; the 10,000 sq ft floor becomes about 3,700m³ and leaves the Angaan. If the ceiling steps, measure each part under its own height and add them. If you measure in feet, multiply square feet by ceiling feet and divide by thirty-five. The 2,000 sq ft page is this step worked at four ceiling heights, and the high-ceilings page is what happens when the height is the whole story.
Rule: the ceiling is the only number on a floor plan that changes the machine, and it is the one number floor plans do not carry. Measure it.
3
Step three
Match each volume to one rung of the ladder
Now the catalogue, one volume at a time. Under about 300 sq ft - a closed lounge, a small studio - one Mountain Breeze reed on the desk, because that is one desk zone and a reed reaches one desk zone by design. From 300 to 750 sq ft, one Sukoon, with the honest note that it is water-based and puts a fine mist into a room of electronics. Between 750 and 1,500 sq ft is the decision point: a Vaayu covers it without effort, so it is bought only for the timer, the key-lock, dry air and one-source reach, and the 1,000 sq ft page is that argument. Up to 1000m³ - about 1,500 to 3,000 sq ft at a normal ceiling - one Vaayu at ₹11,999. From there to 3,000m³ - about 3,000 to 10,000 sq ft - one Angaan at ₹25,999, on the plant where there is one. Past that, or for a floor in the 12,000 to 18,000 sq ft class, one Meenar at ₹38,500. Each volume gets its own rung: a building can honestly come out as one Angaan, one Vaayu and one reed.
The Vaayu - the rung for any volume up to 1000m³: a first floor, a wing on its own unit, a 1,500-3,000 sq ft main floor.
See SOSA Vaayu →

Step four
Take the demonstration off the map - and only sometimes off the count
The live kitchen, the hob and oven demo and the coffee-tasting counter stay unscented while they run; the smell of what is being cooked or brewed is the product demonstration and nothing competes with it. In the calculation that means two different things depending on how the demo zone is built. An open live kitchen at the end of the floor shares the floor's air, so its square feet stay in the cubic-metre sum - the machine has to fill that air whether or not the kitchen is scented - and it comes off the map instead: the one machine sits on the reception side, away from the hood, its schedule is cut out around every demonstration, and the kitchen's extraction runs during and after. A demo kitchen or coffee room behind its own door with its own extraction is a separate volume by step one, and its machine count is zero. Never solve the kitchen with a second machine at the kitchen end; where the machine goes with a live kitchen shows the wall, and why coffee and cooking zones stay unscented is the rule itself.
Rule: an open demo kitchen is in the volume and off the map. A closed one is its own volume with no machine. Neither is ever a reason to add a machine.
5
Step five
Check the count: one machine per volume, never two in one air
Lay the machines against the volumes and check two things. First, every volume has one machine sized to its own cubic metres - not the main floor's machine reaching for a wing it cannot reach, not a reed expected to carry a floor. Second, no volume has two. The commonest error in a large store is two Vaayus at either end of one floor that has passed 1000m³; the honest answer is one Angaan, which costs about what two Vaayus cost and is rated to half as much air again, on one gradient set from the far end and locked. The same rule holds a rung higher: a 10,000 sq ft floor at three and a half metres has passed the Angaan and takes one Meenar, not two Angaans; the 10,000 sq ft page is that decision in full. If the count feels high, recount the volumes - two of them were probably one.
The Angaan - the step up from a Vaayu for one volume past 1000m³, instead of a second Vaayu in the same air.
See SOSA Angaan →
The SOSA principle
A scent-machine count is a count of volumes of air, each measured in cubic metres and matched to one rung of the ladder - never a floor area divided by a coverage figure and rounded up.
Count the volumes. Measure the height. One rung each. Demo zones off the map. No volume with two machines.
The calculation run on one real building
A 9,000 sq ft experience centre on two floors: a ground floor of 6,000 sq ft at four metres with an open live kitchen, a first floor of 2,500 sq ft at three metres on its own air-handling unit, a closed 350 sq ft designer studio, and a 150 sq ft coffee lounge behind glass. Here is the sum, volume by volume.
The SOSA plan
One 9,000 sq ft experience centre, counted volume by volume
| The volume | The arithmetic, and the machine |
|---|---|
|
Ground floor - 6,000 sq ft at four metres, live kitchen open to it
|
About 557 square metres times four - roughly 2,230m³, inside one Angaan's 3,000m³. HVAC-connected on the sales-floor duct; the kitchen's square feet are in the sum, the kitchen is off the map, schedule cut out for demos. View → |
|
First floor - 2,500 sq ft at three metres, own air-handling unit
|
About 232 square metres times three - roughly 700m³, inside one Vaayu's 1000m³. A second volume, so a second machine: wall-mounted high on the supply side, same register, its own far-end level test. View → |
 Designer studio - 350 sq ft, closed door
|
Under 100m³ - one desk zone. One Mountain Breeze reed on the sideboard, three reeds not six, and no machine of any kind. View → |
|
Coffee lounge - 150 sq ft, glazed, own extraction
|
Its own volume by step one, and the demonstration by step four. Machine count zero; nothing on its duct; the door stays shut while it is in use. |
|
The total
|
Three machines for four volumes: one Angaan, one Vaayu, one reed, and one room with nothing. Not, as the area alone would suggest, two Angaans or three Vaayus. |
Each rung of the ladder has its own page: the 500 sq ft studio is where the machine is refused, 1,500 sq ft is the first one-Vaayu floor, 3,000 sq ft is where Vaayu gives way to Angaan by ceiling, and 5,000 sq ft is one Angaan on the plant. The register every machine carries is set in what a premium appliance showroom should smell like. SOSA makes no claim that any of this affects footfall, dwell time, conversion or sales.
Five steps, run on your drawing - one machine per volume of air

A note from Sonal
I keep a scrap of paper in my notebook with the whole method on it, and it is shorter than most of the emails that ask for it. Count the volumes. Measure the ceiling. Square feet times 0.093 times metres. One rung each. Kitchen off the map. Check that nothing has two. The reason I write it out every time is that the first step is the one everyone skips: they send me an area, and an area is not a thing that can be scented. Air can be scented, and a large store has several parcels of it, divided by slabs and air-handling units and doors that stay shut.
The second step is the one that changes the answer most often. A 3,000 sq ft floor is a Vaayu at three metres and an Angaan at four; a 10,000 sq ft floor is an Angaan at three metres and a Meenar at three and a half. Nobody has ever put the ceiling height on a plan they sent me, and it is the only number on the plan that picks the machine. When a floor has outgrown a rung, the answer is the next rung, one machine, never two of the one it outgrew - two sources in one air make a band in the middle and two dials that drift apart.
And the demonstration is off the map before the sum starts. An open live kitchen stays in the cubic metres, because the machine fills that air whether or not the kitchen is scented, but it is never scented while it runs: the one machine on the reception side, the schedule cut out, extraction on. A closed demo room is its own volume with nothing in it. No claim that fragrance moves footfall, dwell time or sales, and no claim about what it does to anything on display - it is an interiors decision, like lighting or music, and never a substitute for extraction.

Frequently asked questions
How do I convert my appliance store's square feet into cubic metres for scent-machine sizing?
Multiply the square feet by 0.093 to get square metres, then by the ceiling height in metres. At a three-metre ceiling, 1,000 sq ft is about 280m³, 3,000 sq ft about 840m³ and 10,000 sq ft about 2,800m³; at four metres each is a third larger. Measuring in feet, multiply square feet by ceiling feet and divide by thirty-five. Where the ceiling steps, measure each part under its own height and add them. The Vaayu is rated to 1000m³, the Angaan to 3,000m³.
How many volumes of air does a two-floor appliance store with a separately air-conditioned wing have?
Three, and therefore three machines. The ground floor is one volume, the first floor above a solid slab is a second, and a wing on its own air-handling unit behind doors that close is a third, even on the ground floor. Each is sized on its own cubic metres - typically an Angaan for a large main floor, a Vaayu for the first floor and a Vaayu or a reed for the wing by its size - in the same register, each level set from its own far end.
Do I subtract the live kitchen and coffee counter from the area before sizing a scent machine?
From the scented map, yes, always; from the cubic metres, only when the demo zone is a closed room. An open live kitchen shares the floor's air, so its square feet stay in the sum, and it is kept unscented by placement and the schedule - machine on the reception side, off during demonstrations, extraction running. A demo kitchen or coffee lounge behind its own door and extraction is a separate volume by the first step, and it gets no machine at all.
What machine covers an appliance store that falls between the Angaan's range and the Meenar's?
The next rung up, on its own, never two of the rung below. The Angaan is rated to 3,000m³, about 10,000 sq ft at three metres; a floor of 10,000 to 12,000 sq ft, or a 10,000 sq ft floor with a ceiling above about three and a quarter metres, has passed it and takes one Meenar at Rs 38,500. Two Angaans in one connected air make two overlapping gradients and two dials, the same fault as two Vaayus a rung down. Confirm the fit with SOSA on the drawing.
Can I size the scent machines for a large appliance store from the floor plan alone?
No, because a floor plan lacks the two things the sum needs. It does not carry the ceiling height, which turns area into cubic metres and decides the rung, and it rarely shows the air-conditioning zoning, which decides how many volumes - and therefore how many machines - the building has. Send the plan with the heights written on it and the AHU zones marked, or the air-conditioning drawing, and the five steps can be run properly and one machine named per volume.
Count the volumes, measure the height, one rung each
