★ SOSA for Indore Businesses
Yes - one machine per floor, each set from its own furthest seat, because raising the output of a ground-floor machine does not move the register upstairs in any controllable way, and the whole of the increase is absorbed by the staff and customers who are standing next to it for eight hours

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.

Separately, one machine per floor. Output is the wrong instrument: turning one up does not carry a register upstairs, it makes the people beside it absorb a level chosen for somebody two floors away.
Quick answers — read this first
Why not just turn the ground-floor machine up? Because the increase is absorbed where the machine is. The people standing beside it take the whole of it, and what reaches the upper floor is uneven and uncontrolled.Do floors behave as separate spaces? Yes. Each floor has its own doors, its own conditioning and its own occupancy, and a stairwell or lightwell connects them without distributing anything evenly.
What is the right specification? One machine per floor, each set from the furthest seat on that floor and key-locked, all of them carrying the same register.
The short answer
Short answer: separately - one machine per floor, each set from its own furthest seat, because raising one machine's output is absorbed by the people standing next to it rather than carried upstairs.
The pick: a SOSA Vaayu (₹11,999) per floor, or a SOSA Angaan (₹25,999) where one floor is a single connected volume above about 3,000 sq ft on its own duct.
Next step: stand on the top floor at four in the afternoon and judge that floor on its own. Or ask for a scenting plan for your space.

Straight answer
Should an interior showroom scent each floor separately rather than increasing one machine's output?
Separately, and the reason is not that one machine is too small - it is that output is the wrong instrument for the job being asked of it. The request behind the question is really about distance: the register reads well on the ground floor and reads faintly on the first, so the instinct is to turn the ground-floor machine up until the first floor is covered. But intensity does not convert into reach in a controllable way. A machine delivers into the space it stands in, and what leaves that space does so through a stairwell or a lightwell, unevenly, at the mercy of doors that open and shut and of whatever the air conditioning on each floor is doing. So raising the level produces two effects, and only one of them is wanted. The one that is wanted is a slight change on the floor above, arriving in bursts rather than as a setting. The one that is not is a large, permanent change on the floor the machine is on. That second effect is the argument on its own, and it is worth stating in terms of people rather than air. The visitor upstairs you are trying to reach is in the building for perhaps twenty minutes. The salesperson standing four metres from the machine on the ground floor is there for eight hours, five or six days a week, and they are the ones absorbing every increment you added for somebody two floors away. A specification that quietly charges the staff for the customer's coverage is a bad specification even when nobody complains, and in practice it is also the one that produces the eventual complaint. There is a second reason floors want their own machines, which has nothing to do with strength. Floors in an interior showroom are rarely the same room twice. The ground floor is hard: stone, tile, glass, a door to the street that opens forty times an hour. The first floor is soft: fabric, rugs, upholstery, mattresses, curtain displays, and frequently a lower ceiling. Those two rooms need different settings to arrive at the same perceived level, and one machine cannot hold two settings. Nor are they occupied the same way - and a display floor has its own limits on what a register can be asked to do. So the specification is plain. One machine per floor, each set from the furthest seat on that floor at the end of the longest visit, each key-locked at that level, and all of them carrying one register rather than a register per floor - two registers in one building is two smells and no identity. Where a single floor is one connected visitor-facing volume above about 3,000 sq ft, the step is a duct-mounted machine on the run that serves that floor only rather than a second machine sharing the air with the first. And the closed rooms on every floor carry nothing - a one-to-one room is never a lower setting. A SOSA Vaayu at ₹11,999 per floor, or a SOSA Angaan at ₹25,999 on a dedicated duct. 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 one-to-one rooms - design cabins, consultation rooms, quotation desks behind a door - 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.
Separately. Raising one machine's output is absorbed by the people standing next to it rather than carried upstairs, and the two floors are different rooms anyway - hard downstairs, soft upstairs - so they need different settings to read the same.
Per floor: SOSA Vaayu at ₹11,999. One large floor on the duct: SOSA Angaan at ₹25,999.

The honest ladder
One source for the visitor zone, sized to the floor
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.
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
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, showroom or office 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
Why output is the wrong instrument
The question sounds like a sizing decision. It is really a question about who absorbs the increase, and about two rooms that are not alike.
1
The instrument
Intensity is not distance
A machine delivers into the space it stands in. What leaves through a stairwell does so unevenly and in bursts, governed by doors and by each floor's own conditioning.
Rule: reach is placement, never volume.
2
Who pays
Eight hours against twenty minutes
The visitor upstairs stays twenty minutes. The salesperson four metres from the machine is there all day, absorbing every increment added for somebody two floors away.
Test: never charge staff for a customer's coverage.
3
Two rooms
Hard downstairs, soft upstairs
Stone, tile, glass and a street door on the ground floor; fabric, rugs, upholstery and a lower ceiling above. They need different settings to arrive at the same perceived level.
Rule: one machine cannot hold two settings.
4
Setting
Each floor from its own furthest seat
Set standing at the end of that floor at the end of the longest visit, then key-locked, so a shift change or a new manager cannot move it.
Test: judge each floor on that floor.
5
Register
One register, several machines
Every floor carries the same register. Two registers in one building is two smells and no identity, and it is the commonest failure in a multi-floor showroom.
Rule: and every closed room carries nothing.
The SOSA principle
The customer upstairs is in the building for twenty minutes. The salesperson four metres from the machine is there for eight hours, and they absorb every increment added for somebody two floors away.
Which is why a louder machine downstairs is not a cheaper way to reach the first floor. It is a transfer of the whole cost onto the people who cannot leave the room.
Multi-floor showrooms, question by question
What output actually does, who absorbs it, and why two floors are two different rooms.
The SOSA Hyderabad table
One machine per floor, or one louder machine
| The question | The answer |
|---|---|
|
Does raising the output reach the next floor?
|
Not in any controllable way. What leaves through a stairwell arrives in bursts, governed by doors and by each floor's own air conditioning. |
|
Where does the increase actually go?
|
Into the floor the machine is on. The people standing beside it absorb the whole of a level that was chosen for somebody two floors above. |
|
Why are floors different rooms?
|
The ground floor is hard - stone, glass, a street door. The upper floor is soft - fabric, rugs, upholstery - so the same setting reads differently. |
|
How is each floor set?
|
From the furthest seat on that floor at the end of the longest visit, then key-locked so the level survives a shift change. |
|
When is a duct-mounted machine the step?
|
Where one floor is a single connected visitor-facing volume above about 3,000 sq ft - an Angaan at ₹25,999 on that floor's own run. |
The display-floor version is what a register can be asked to do across vignettes, the household version is why a house is not one machine either, and the specification version is scenting written into a practice's spec. SOSA makes no claim that fragrance affects what anybody buys or decides.
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.
Reach is a placement and machine question. It has never been a volume question, and in a two-floor building the volume answer sends the bill to the staff.

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.

Frequently asked questions
Should each showroom floor have its own machine?
Yes. One machine per floor, each set from the furthest seat on that floor and key-locked, with every floor carrying the same register.
Why not increase one machine's output instead?
Because the increase is absorbed on the floor the machine is on, and what reaches the floor above arrives unevenly and in bursts.
Who pays for a louder machine downstairs?
The staff standing near it for eight hours a day, in exchange for a slight change for a visitor who is upstairs for twenty minutes.
Why do two floors need different settings?
Because a hard ground floor with stone, glass and a street door and a soft upper floor with fabric and rugs do not read the same at one level.
When does a duct-mounted machine make sense?
Where one floor is a single connected visitor-facing volume above about 3,000 sq ft, on the run that serves that floor only.
