★ SOSA for Hyderabad Businesses
By reading the step it settles on rather than the coverage rating - a machine that is right runs on the second or third step with room to move in both directions, a machine that is too small sits pinned at the top, and a machine that is too large has a lowest step already above what the furthest seat wants

What does too large look like? A machine whose lowest step already delivers more than the furthest seat wants. Surplus capacity is assumed harmless, and it is not, because there is no way down.
What has to be measured first? Connected volume rather than floor area, and the straight-line distance from the intended source to the furthest seat, which decides whether one source reaches at all.

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.

Read it off the step it runs at, not the rating. Pinned at the top is too small. A lowest step that is still too much is too large - and that failure surprises people.
Quick answers — read this first
How do I judge whether a machine is the right size? By the setting it ends up running at. Right means a low step with headroom in both directions; too small means pinned at maximum and still short at the furthest seat.What does too large look like? A machine whose lowest step already delivers more than the furthest seat wants. Surplus capacity is assumed harmless, and it is not, because there is no way down.
What has to be measured first? Connected volume rather than floor area, and the straight-line distance from the intended source to the furthest seat, which decides whether one source reaches at all.
The short answer
Short answer: by the step it settles on. A low step with room to move both ways is right; pinned at the top is too small; a lowest step that is already too much is too large.
The pick: a SOSA Vaayu (₹11,999) run on its lower steps, a SOSA Sukoon (₹1,899) for one enclosed room, or an SOSA Angaan (₹25,999) above about 3,000 sq ft of one volume.
Next step: multiply your connected floor area by the ceiling height and pace out the furthest seat. Or ask for a scenting plan for your space.

Straight answer
How can I tell whether a SOSA Vaayu is too large, too small or appropriate for my Uppal business?
By looking at the setting the machine ends up running at rather than at the coverage figure on the box, because size is a relationship between a machine and a room and only one of those two is described on a specification sheet. The reading is simple once you know what to look for. A machine that is correctly sized settles on a low step - the second or third of its range - and stays there, with room to move up on a full evening and room to come down on a quiet morning. A machine that is too small is easy to spot because it sits pinned at the top of its range and the furthest seat still reports nothing. Everybody recognises that failure. The one almost nobody anticipates is the opposite: a machine whose lowest available step already delivers more than the furthest seat wants. That business has no way down. It can switch the machine off or it can run it too high, and it will spend the next two years cycling between those two states while blaming the fragrance. Surplus capacity is assumed to be harmless in the way surplus horsepower is harmless, and in a diffuser it is not, because the useful range of a machine is bounded at the bottom as well as the top. So the question becomes how to predict the step before you buy, and there are exactly three inputs. The first is connected volume, not floor area. Multiply the floor area of every space that is joined to the visitor zone by an opening that stays open, by the ceiling height, and add them up. A 700 square foot reception under a nine-foot ceiling is 6,300 cubic feet; the same reception under fourteen feet is 9,800, which is more than half as much again for a plan that looks identical. The second is the straight-line distance from the intended source to the furthest seat, and this is the input that decides whether a single machine is viable at all rather than how hard it must work. Beyond roughly twelve to fifteen metres in a real room with furniture and an air conditioner, one source stops being a source for the far end and becomes a source for the near end - and the answer then is a different position or a duct-mounted unit, never a higher setting. Which volumes are genuinely connected is decided by which doors are shut. The third input is not about the building at all: how many people can reach the dial? Headroom is only an asset if nobody can spend it. In a business where six people can adjust a machine, a unit with plenty of range in hand becomes a unit at maximum by Thursday, which is why the key-lock is what makes a comfortably sized machine safe rather than dangerous - and why the lock is bought before the capacity is used. Put the three together and the practical rule is: choose a rating comfortably above your connected volume, expect to run it low, and lock it. If the arithmetic puts you above about 3,000 square feet of one connected visitor-facing volume, the step is one duct-mounted unit rather than a second machine in the same air mass. If your space is one enclosed room of 270 to 320 square feet, a Vaayu is being bought for the lock, the timer and a waterless output rather than for reach, which is a perfectly good reason as long as it is said out loud. 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. A SOSA Vaayu at ₹11,999, a SOSA Sukoon at ₹1,899 for one enclosed room, or an SOSA Angaan at ₹25,999 on the duct. Closed treatment rooms, consultation cabins and any closed one-to-one room are never scented. A named seat away from the source is kept genuinely fragrance-free and offered rather than waiting to be 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.
By the step it settles on. A low step with headroom both ways is right; pinned at maximum and still short is too small; a lowest step that already gives more than the furthest seat wants is too large, and that one has no way down.
Sized to run low: SOSA Vaayu at ₹11,999, or an SOSA Angaan at ₹25,999 above 3,000 sq ft.

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.

The register - or the whole answer where reception is one seating zone
SOSA Mountain Breeze Reed Diffuser
Himalayan pine, sage and Indian cedar - the driest register SOSA makes and the house default, because it reads as a considered room rather than as a hotel lobby. Where reception is a single seating group, this bottle at the staff end of the desk at ₹849 for 50ml carries the register on its own, three or four reeds in, flipped weekly; 130ml at ₹1,349 lasts 14-18 weeks. Alcohol-free, phthalate-free, six fibre reeds, and carried out of the room in seconds if a client asks.
From ₹849
Three inputs, and one reading
Size is a relationship between a machine and a room, and only one of the two is printed on a box.
1
The reading
Which step does it settle on?
Right is the second or third step of the range, held there, with room to move up for a full evening and down for a quiet morning.
Test: judge the setting, not the rating.
2
Too large
No way down is a real failure
A machine whose lowest step already gives more than the furthest seat wants leaves a business switching between off and too high for two years, usually blaming the fragrance.
Rule: surplus capacity is not harmless here.
3
Volume
Cubic feet, not square feet
700 sq ft under nine feet is 6,300 cubic feet; the same plan under fourteen feet is 9,800. Add every space joined by an opening that stays open.
Test: two identical plans, two different rooms.
4
Distance
Source to furthest seat
Beyond roughly twelve to fifteen metres in a furnished, air-conditioned room, one source serves the near end only. The answer is a position or a duct, never a higher step.
Rule: this decides viability, not effort.
5
The dial
Headroom needs a lock
Where six people can adjust a machine, a unit with range in hand is a unit at maximum by Thursday. The key-lock is what makes comfortable sizing safe.
Rule: buy the lock before you use the capacity.
The SOSA principle
Everybody recognises a machine that is too small, because it sits at maximum and the far end still reports nothing. Almost nobody anticipates the opposite: a lowest step that is already too much, and no way down from it.
Which is why the right target is a rating comfortably above the volume, run deliberately low, and locked so the headroom cannot be spent.
Sizing a machine, question by question
What to measure, what the setting tells you, and when a different machine is the answer.
The SOSA Hyderabad table
Too large, too small or right
| The question | The answer |
|---|---|
|
How is the right size recognised?
|
The machine settles on the second or third step of its range and stays there, with room to move up on a busy evening and down on a quiet morning. |
|
What does too small look like?
|
Pinned at the top of the range while the furthest seat still reports nothing, which is the failure everybody already recognises. |
|
What does too large look like?
|
A lowest step that already delivers more than the furthest seat wants, leaving a choice between off and too high and no setting in between. |
|
What has to be measured?
|
Connected volume in cubic feet rather than floor area, and the straight-line distance from the intended source to the furthest seat. |
 When is a bigger machine the right answer?
|
Above about 3,000 sq ft of one connected visitor volume, where the step is an Angaan (₹25,999) on the duct rather than a second Vaayu. |
The threshold version is when a business is big enough for Vaayu, the small-room version is whether a machine can overpower 600 sq ft, and the ceiling version is very high ceilings. SOSA makes no claim that fragrance removes or reduces anything in the air.
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 machine with no way up is obviously wrong. A machine with no way down is just as wrong, and it takes two years and a lot of blamed fragrance before anybody says so.

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
By looking at the setting the machine ends up running at rather than at the coverage figure on the box, because size is a relationship between a machine and a room, and only one of those two is described on a specification sheet. A correctly sized machine settles on a low step - the second or third of its range - and stays there, with room to move up on a full evening and down on a quiet morning. A machine that is too small is easy to spot: pinned at the top and the furthest seat still reports nothing. Everybody recognises that one.
The failure almost nobody anticipates is the opposite. A machine whose lowest available step already delivers more than the furthest seat wants has no way down. It can be switched off or run too high, and the business spends two years cycling between those two states while blaming the fragrance. Surplus capacity is assumed harmless the way surplus horsepower is harmless, and in a diffuser it is not, because the useful range is bounded at the bottom as well as the top. So predict the step before buying, with three inputs: connected volume rather than floor area, since 700 square feet under nine feet is 6,300 cubic feet and the same plan under fourteen feet is 9,800; and the straight-line distance from the intended source to the furthest seat, which decides whether one source is viable at all rather than how hard it works.

Fragrance does not remove or reduce anything in the air, it treats nothing and relieves nothing, and I make no claim that it does.

Frequently asked questions
How do I know if a scent machine is the right size?
By the step it settles on. A low step held steady, with room to move up on a busy evening and down on a quiet morning, is what correct sizing looks like.
What are the signs a machine is too small?
It runs pinned at the top of its range and the furthest seat in the waiting area still reports nothing at the end of a normal day.
Can a machine be too large for a space?
Yes, and it is the failure people do not expect. If the lowest step already gives more than the furthest seat wants, there is no setting between off and too high.
Should I calculate floor area or volume?
Volume. Multiply the area of every space joined by an opening that stays open by the ceiling height, because two identical plans under different ceilings are different rooms.
When is a larger duct-mounted machine the right step?
Above roughly 3,000 sq ft of one connected visitor-facing volume, where a second machine in the same air mass would simply drift away from the first.
Work out your cubic feet, then the furthest seat
SOSA — Studio Scenting read the step, not the rating
A correctly sized machine settles on the second or third step of its range with room to move both ways. Pinned at the top and still short at the far end is too small. A lowest step that already gives more than the furthest seat wants is too large, and that business has no way down. Measure connected volume in cubic feet, pace the distance from source to furthest seat, and lock the dial so the headroom cannot be spent. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
