Can I measure the effect on my business? No. There is no control version of your business running without it, and everything else moved at the same time - season, pricing, staff, competitors, the festival calendar.
What if a supplier quotes a figure? Then they are quoting a number nobody can produce. No method available to a single business can separate a fragrance from every other thing that changed that quarter.

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.
Five things, and all five are operational. Cost per day. Refill against prediction. Whether the locked level moved. Whether the fragrance-free seat is offered. Whether anybody complained. A commercial effect is not measurable.
Quick answers — read this first
What can actually be measured? Running cost per day, the refill interval against the predicted one, whether the locked level has drifted, whether the fragrance-free seat is genuinely being offered, and whether anybody has complained.Can I measure the effect on my business? No. There is no control version of your business running without it, and everything else moved at the same time - season, pricing, staff, competitors, the festival calendar.
What if a supplier quotes a figure? Then they are quoting a number nobody can produce. No method available to a single business can separate a fragrance from every other thing that changed that quarter.
The short answer
Short answer: five operational things: cost per day, refill interval against prediction, whether the locked level drifted, whether the fragrance-free seat is offered, and whether anybody complained. A commercial effect is not measurable.
The pick: a machine you can actually audit - a SOSA Vaayu (₹11,999) with a key-lock, a timer and a stated refill interval to check the real one against.
Next step: write today's date on the refill bottle before you fit it. Or ask for a scenting plan for your space.

Straight answer
What should a business measure after installing commercial scenting?
Five things, and the first honest statement in this answer is about what is not on the list. A commercial effect cannot be measured here, and anybody who offers you one is quoting a number nobody can produce. The reason is not modesty, it is method. To attribute a change in your business to a fragrance you would need a version of your own business running in the same months without it, and you do not have one - and in the quarter you installed a machine, the season changed, the festival calendar moved, prices moved, staff changed, a competitor opened or closed, and your own attention was on the new thing. No arrangement available to a single business separates one small ambience change from all of that. So a supplier quoting footfall, enquiries, conversions, average spend, retention or dwell time is not being optimistic; they are selling a figure that has no method behind it, and the correct response is to ask exactly how it was produced and to listen to the answer. Here is the useful test to keep: could this number have been produced with the machine switched off? If the honest answer is that you would never have known the difference, it is not a measurement. Now the five things that genuinely are measurable, all of them operational, all checkable by one person in a few minutes. One: running cost per day. Divide the price of a refill by the number of days it actually lasted, and you have a rupee figure you can put beside every other running cost in the business. It is usually far smaller than owners expect, and it is the only cost number in this whole subject that is real. Two: the refill interval against the prediction. Write the date on the bottle when you fit it. A 400ml tank quoted at roughly 75-90 days that empties in forty is telling you something specific - the level is higher than you set it, or the machine is running more hours than you think, and both are worth knowing. Three: has the locked level moved? Note the setting on the day you lock it and check it at every refill. A level that has drifted upward is the single commonest failure in commercial scenting, and it happens because whoever adjusts it is usually whoever has been in the room longest. Four: is the fragrance-free seat actually being offered? This is an audit, not a policy question, and the way to run it is to ask three members of staff separately to show you the seat and tell you what they say when they offer it. If two of them cannot, the policy exists only on paper. Five: has anybody complained - and would you hear about it? A complaint count of zero means nothing without a route for it, so the measurable is really whether reception has been told that a comment about the smell gets written down and shown to you rather than handled and forgotten. The fragrance-free arrangement is only real if it is offered rather than requested. Review all five at the first refill, then twice a year, and that is the entire honest measurement programme. A SOSA Vaayu at ₹11,999 is auditable in exactly this way, with a key-lock to check, a timer to read and a stated interval to compare against. 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 - consultation cabins, treatment rooms, any room where a visitor is alone with a professional - are never scented. A named seat away from the source is kept genuinely fragrance-free and offered at the desk. 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.
Cost per day, refill interval against the prediction, whether the locked level has moved, whether the fragrance-free seat is genuinely offered, and whether a complaint would ever reach you. A commercial effect is not measurable by any business.
Auditable by design: SOSA Vaayu at ₹11,999 - key-lock, timer and a stated refill interval to check the real one against.

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.
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
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
The five things, and the one test that keeps them honest
Every item here is checkable by one person in a few minutes. That is the standard a measurable has to meet.
1
Cost
Rupees per day
Refill price divided by the days it actually lasted. It sits beside every other running cost in the business, and it is the only cost figure in this subject that is real.
Test: usually smaller than owners expect.
2
Interval
Prediction against reality
Write the date on the bottle when you fit it. A tank quoted at 75-90 days that empties in forty says the level is higher than you set it or the run is longer than you think.
Test: the bottle is your instrument.
3
Drift
Has the locked level moved?
Note the setting on the day you lock it and check at every refill. Upward drift is the commonest failure in commercial scenting, because whoever adjusts it has been in the room longest.
Test: one number, written down once.
4
The seat
Offered, not merely available
Ask three staff separately to show you the fragrance-free seat and say what they offer. If two cannot, the arrangement exists on paper and nowhere else.
Test: this is an audit, not a policy.
5
Complaints
Zero means nothing without a route
The real measurable is whether reception knows that a comment about the smell gets written down and shown to you, rather than handled politely and forgotten at the desk.
Rule: build the route before counting.
The SOSA principle
The test for any proposed metric is one question: could this number have been produced with the machine switched off? If you would never have known the difference, it was not a measurement.
Applied honestly, that question removes every commercial figure from the list and leaves five operational ones, all of which a single member of staff can check in a few minutes.
Measuring after installation, question by question
What is genuinely checkable, and why the commercial numbers are not.
The SOSA Hyderabad table
What can and cannot be measured
| The question | The answer |
|---|---|
|
Can I measure the effect on my business?
|
No. There is no version of your business running the same months without it, and season, pricing, staff and competitors all moved at the same time. |
|
What if a supplier quotes footfall or conversion?
|
Ask exactly how the figure was produced. No method available to a single business separates one ambience change from everything else that quarter. |
|
What is the first real measurable?
|
Running cost per day: refill price divided by the days it actually lasted. It is the only cost figure in this subject that is genuinely real. |
|
What does a short refill interval tell me?
|
That the level is higher than you set it or the machine runs longer than you think. Both are worth knowing, and the bottle date reveals both. |
|
What about the fragrance-free seat?
|
Audit it. Ask three staff separately to show it and say what they offer. A Vaayu (₹11,999) makes the level and the timer checkable too. |
The schedule version is programming to traffic rather than to business hours, the staged version is one zone before expanding, and the metric-rejecting version is whether footfall is the wrong metric entirely. 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.
Could this number have been produced with the machine switched off? If you would never have known the difference, it was not a measurement - and that question deletes every commercial figure on the usual list.

 SOSA Boond
|
A director's cabin, a small reception or a single desk | One small enclosed space only, on low; never in a closed treatment room or consultation cabin | ₹899 View → |
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
Five things, and the first honest statement is about what is not on the list. A commercial effect cannot be measured here, and anybody offering you one is quoting a number nobody can produce. That is method, not modesty. To attribute a change in your business to a fragrance you would need a version of your own business running the same months without it, and you do not have one. In the quarter you installed a machine, the season changed, the festival calendar moved, prices moved, staff changed, a competitor opened or closed, and your own attention was on the new thing. So a supplier quoting footfall, enquiries, conversions, average spend, retention or dwell time is selling a figure with no method behind it. Ask exactly how it was produced, and listen to the answer.
The test I keep is one question: could this number have been produced with the machine switched off? If the honest answer is that you would never have known the difference, it is not a measurement. What survives that question is five operational things. Running cost per day - refill price divided by the days it actually lasted, which is the only real cost figure in this subject and is usually smaller than owners expect. The refill interval against the prediction, which means writing the date on the bottle when you fit it: a tank quoted at 75-90 days that empties in forty is telling you the level is higher than you set it or the run is longer than you think. And whether the locked level has moved, which is the commonest failure of all, because whoever adjusts a setting is usually whoever has been standing in the room longest.
The last two are the ones I care about most. Is the fragrance-free seat actually being offered? That is an audit rather than a policy question, and the way to run it is to ask three members of staff separately to show you the seat and tell you what they say when they offer it - if two of them cannot, it exists on paper and nowhere else. And has anybody complained, which means asking first whether a complaint would ever reach you: a count of zero is meaningless unless reception has been told that a comment about the smell gets written down and shown to you rather than handled and forgotten. Review all five at the first refill and then twice a year. A SOSA Vaayu at ₹11,999 is auditable in exactly that way, with a key-lock to check, a timer to read and a stated interval to compare against. Fragrance does not remove or reduce anything in the air, it treats nothing and relieves nothing, and I make no claim that it does. Closed treatment rooms and consultation cabins are never scented.

Frequently asked questions
What can a business actually measure after installing scenting?
Running cost per day, the refill interval against the predicted one, whether the locked level has drifted, whether the fragrance-free seat is offered, and whether anybody complained.
Can the commercial effect of a fragrance be measured?
No. There is no version of the same business running without it in the same months, and season, pricing, staff and competitors all changed at once.
What should I do if a supplier quotes a footfall or conversion figure?
Ask exactly how it was produced. No method available to a single business can separate one ambience change from everything else that moved that quarter.
How do I check the refill interval?
Write the date on the bottle when you fit it. A tank quoted at 75-90 days that empties in forty means a higher level or longer run hours than you think.
How do I know the fragrance-free seat is real?
Ask three staff separately to show you the seat and say what they offer. If two cannot, the arrangement exists only on paper.
Date the bottle before you fit it
SOSA — Studio Scenting operational only
Five measurables, all operational: running cost per day, the refill interval against the predicted one, whether the locked level has drifted, whether the fragrance-free seat is genuinely offered, and whether a complaint would ever reach you. A commercial effect is not measurable, because no business has a version of itself running the same months without the machine - so a quoted figure for footfall, conversions, spend or retention has no method behind it. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
