Why write a target in words rather than a dial number? Because a dial number is meaningless once the unit has been cleaned, the fragrance changed or the season turned. A sentence describing how the room should read survives all of that.
What single rule prevents drift? That the level changes only at a scheduled recheck, by the named owner, recorded. Drift happens through small reasonable adjustments that nobody reverses.

Facts verified September 2026: Fragrance is an ambience decision only and is never a substitute for ventilation, cleaning or source control. Coverage is determined by air volume including ceiling height rather than by floor area, and fragrance does not travel through closed doors, so a multi-room premises is specified by counting qualifying volumes rather than rooms. Open and semi-open spaces cannot hold fragrance at any output. Perceived intensity falls with habituation, which is why an unowned setting tends to be increased over time; a named owner, a written level and a fixed review date are part of the specification. Running cost comprises fragrance consumption, electricity and filter upkeep and varies with runtime, setting and volume. SOSA makes no claim that ambient scenting increases footfall, enquiries, conversion, retention, referrals, transaction value or customer spend, and no such claim should be made on the strength of this guide. Where association language is used it is descriptive of ordinary experience - people come to associate a place with how it feels - and is not a commercial performance claim. SOSA range as listed on sosahomeandbody.com in September 2026: reed diffusers from ₹749 (alcohol-free reed oil, 50ml and 130ml); Boond ultrasonic ₹899 (300ml); Sukoon ultrasonic ₹1,899 (500ml); Megh ultrasonic ₹3,499 (6L); Hotel Collection diffuser fragrance from ₹299 (15ml, 100ml and 300ml, seven scents); SOSA Safar waterless car and travel diffuser ₹3,999; SOSA Vaayu ₹11,999 - waterless cold-air nebulising machine, coverage up to 1000m³ (about 2,000 to 3,000 sq ft), 400ml refillable tank, Bluetooth app and onboard control, 1h/4h/8h/24h timer scheduling, adjustable intensity, operation under 38 dB, auto-stop and key-lock, freestanding or wall and HVAC mount; SOSA Aangan ₹25,999 - HVAC nebulising machine, 800ml, specified for roughly 8,000 to 10,000 sq ft, under 42 dB; SOSA Meenar ₹38,500 - specified for roughly 12,000 to 18,000 sq ft. Ultrasonic diffusers and machines run on the Hotel Collection fragrance; reed diffusers use their own alcohol-free reed oil, and the two are not interchangeable. The Hotel Collection scents are SOSA's own interpretations inspired by the world's finest hotels; SOSA is independent and not affiliated with, endorsed by or associated with any hotel brand. SOSA's fragrances are made in India; the scent machines are imported. SOSA's paid on-site commercial walkthrough is ₹1,500 and is available in Pune only; remote sizing from the client's own measurements over WhatsApp is the route everywhere else.

One page, nine clauses, and one rule that does most of the work: nobody changes the level except at a scheduled recheck.
Quick answers — read this first
What should a scenting SOP contain? The perceived target in words, which rooms are and are not scented, the schedule, who owns it, who judges it, the recheck dates, the maintenance interval, the record to keep, and the rule that nobody adjusts the level between rechecks.Why write a target in words rather than a dial number? Because a dial number is meaningless once the unit has been cleaned, the fragrance changed or the season turned. A sentence describing how the room should read survives all of that.
What single rule prevents drift? That the level changes only at a scheduled recheck, by the named owner, recorded. Drift happens through small reasonable adjustments that nobody reverses.
The short answer
Short answer: One page. And nobody touches the level between rechecks.
The pick: the SOSA Vaayu at ₹11,999 per enclosed room on Hotel Collection fragrance from ₹299, with an Aangan at ₹25,999 or a Meenar at ₹38,500 only where the air volume genuinely calls for it.

In this guide
Commercial scenting goes wrong in a predictable order: somebody buys a machine to cover a smell that has a source, puts it where the socket is, runs it at full intensity because day one felt weak, and ends up with a room people comment on for the wrong reason. Source first, air volume second, unscented zones written down third, low intensity and a schedule fourth. This guide walks that sequence, with the real SOSA machine range at each size.

Straight answer
What should a commercial scenting SOP actually say?
Nine clauses, one page, and one of them does most of the work. One: the perceived target, in words. Just detectable on entering from outside, not detectable after ten minutes seated. Never a dial number, which means nothing once the unit has been cleaned, the fragrance changed or the season turned. Two: the room list, both halves. Which rooms are scented, and explicitly which are not - staff work floors, corridors, stores, semi-open spaces, and anywhere with a smell requiring source control. Writing down the never list prevents somebody local deciding differently a year later, and it is the clause that saves the most trouble. Three: the schedule. On shortly before customers arrive, off when the space empties, nothing overnight, nothing on closed days. Four: the named owner, who holds the key and is the only person permitted to change anything. Five: the judge, who is somebody arriving from outside and is never the person who set it. Six: the recheck dates. Four a year in Ahmedabad - late February, late June, late September, late November - as recurring calendar items with the owner's name on them. Seven: maintenance. The interval per unit according to where it sits, the method from the product's own instructions, and a check of the fragrance level at the same visit. Eight: the record. Date, room, setting, who changed it, why, and who judged it. One page in a book is enough, and it is what lets you answer the question of how the room got heavy. Nine, and this is the one that matters: nobody changes the level except at a scheduled recheck. Not when a visitor comments, not when somebody who has been inside since morning says they cannot smell it, not when a senior person walks past and asks. Those requests get written into the record and addressed at the next recheck. Drift is not caused by bad decisions; it is caused by a series of individually reasonable adjustments that nobody ever reverses, and this clause is the only thing that reliably stops it. Two clauses worth adding in specific cases. If you have a clinic, a childcare setting or a food business, a line stating that fragrance-free areas exist and that the fragrance-free option is offered rather than waited for. If you are a group, a line requiring the same register across sites with levels set independently per site. What not to put in it. Any claim about what the fragrance does for the business. SOSA makes no claim that ambient scenting affects footfall, enquiries, dwell time, conversion or sales, and we make no therapeutic, psychological or air-purification claims for any fragrance. An SOP that contains a commercial claim is a document somebody will eventually quote back at you. The equipment context. A Vaayu at ₹11,999 per enclosed room on fragrance from ₹299, key-locked, is the normal arrangement, and the SOP is what makes it still be right in year three. Fragrance is an ambience decision and never a substitute for ventilation, cleaning or source control. A portion of every order supports girl-child education through Nanhi Kali.
One line: write the never-scented list down. It saves the most trouble.
Key-locked, written target, four dates: ₹11,999. Fragrance from ₹299.
₹11,999
Nine clauses worth writing
Eight of the nine clauses are administration. The ninth is the one that actually prevents drift.
01
Write the never list
Not just the yes list
Staff floors, corridors, stores, semi-open spaces and source-control cases, written down explicitly. It prevents somebody deciding differently in a year's time, and it is the clause that saves the most trouble over a building's life.
Tip: The no list matters more than the yes list.
02
Words, not numbers
A dial position expires
Once the unit is cleaned, the fragrance replaced or the season turned, the number means nothing. A sentence describing how the room should read is still usable in three years, which is the whole point of writing it.
Tip: A number tells you nothing next year.
03
One clause does the work
No changes between rechecks
Requests from visitors, adapted staff and senior people get recorded and addressed at the next recheck rather than acted on. Drift is a sequence of reasonable adjustments nobody reverses, and this is what stops the sequence.
Tip: Log the request. Do not turn the dial.
The SOSA principle
Drift is not caused by bad decisions. It is caused by reasonable ones nobody reverses.
Which is why the clause that forbids mid-season changes is the one that matters.
One register, written down
One register named in the document, with the level left as a written perceived target rather than a setting, so that the document survives a change of machine or fragrance batch.

The SOSA commercial range
Whatever the space, the method is the same: find the source of any smell and fix it, draw the air volume rather than the floor plan, write down which zones stay unscented, then set a low intensity and a schedule. Every SOSA fragrance is alcohol-free and made in India, and a portion of every order supports girl-child education through Nanhi Kali. Here is the range by the size of space it is honestly built for.
The SOSA commercial range
Sized by air volume, not by ambition - from a ₹749 reed diffuser to the ₹38,500 Meenar
| Option | Right for | What it actually is | Price |
|---|---|---|---|
| Reed diffusers | One small room, no power point, no maintenance | Alcohol-free reed oil, passive, silent. Good for a single cabin or a small front desk, not for a hall | from ₹749 |
| Boond / Sukoon ultrasonic | A desk, a single cabin, a small reception | Water-based cool mist; runs on Hotel Collection fragrance, adds a little humidity to the room | ₹899 / ₹1,899 |
| Megh ultrasonic (6L) | A larger waiting area where visible mist is wanted | 6L tank, water-based. Still a room machine rather than a floor machine | ₹3,499 |
| SOSA Vaayu | Reception, lounge, corridor, a contained showroom floor | Waterless cold-air, up to 1000m³ (about 2,000 to 3,000 sq ft), 400ml tank, app and 1h/4h/8h/24h timers, under 38 dB, key-lock for public areas | ₹11,999 |
| SOSA Aangan | Large premises, or scenting carried on the building's own HVAC | HVAC-mount nebulising machine, 800ml, roughly 8,000 to 10,000 sq ft, under 42 dB | ₹25,999 |
| SOSA Meenar | Hotels, large showrooms, venues, corporate floors | The largest machine in the range, specified for roughly 12,000 to 18,000 sq ft | ₹38,500 |
| Hotel Collection fragrance | The fragrance the machines actually run on | Seven scents, 15ml / 100ml / 300ml. SOSA's own interpretations; SOSA is independent and not affiliated with any hotel brand | from ₹299 |
Honest notes on a whole-business decision: fragrance is an ambience decision only and is never a substitute for ventilation, cleaning or source control, and any odour with a source is a source-control matter first. Machines are specified by air volume including ceiling height rather than by floor area or by budget, and a larger machine is not a better one in a smaller volume. Open and semi-open spaces cannot hold fragrance at any output. Levels drift upward when nobody owns them, so a named owner, a written setting and a fixed review date are part of the specification rather than an afterthought. SOSA makes no claim that ambient scenting increases footfall, enquiries, conversion, retention, referrals, transaction value or customer spend, and no such claim should be made on the strength of this guide. Where association language is used it is descriptive of ordinary experience - people come to associate a place with how it feels - and is not a commercial performance claim. Ultrasonic diffusers and the machines run on the Hotel Collection fragrance; reed diffusers use their own alcohol-free reed oil, and the two are not interchangeable. The Hotel Collection scents are SOSA's own interpretations inspired by the world's finest hotels; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or associated with any hotel brand. SOSA's fragrances are made in India; the scent machines are imported. Listed prices are store prices and are subject to change.

A note from Sonal
By the time somebody in Ahmedabad calls me about scenting, they have usually decided to buy something and want help choosing it. The most useful thing I can do at that point is slow the order down by one conversation, because the sequence matters more than the product: source control, then ventilation, then cleaning, then lighting and upkeep, and only then the air. A machine bought before those are settled will be blamed for problems it was never able to solve.
Then the sizing, which is where money is most often wasted in both directions. Air volume decides the machine, not floor area and not budget. A double-height gallery and a low-ceilinged reception of identical floor area are different problems, and a business that buys the largest unit because it is the most expensive usually ends up running it at its lowest setting forever. If the smallest machine is enough, I will say so.
And the part nobody plans for: ownership. A level that nobody owns drifts upward, because staff stop noticing it and turn it up. One named person, one written setting, one fixed date to check it - that is the whole of the governance, and it is the difference between a room that reads as considered in year three and one that reads as heavy. Fragrance is an ambience decision, never a substitute for ventilation, cleaning or source control, and I make no claim about what it returns commercially. WhatsApp +91 96192 18531. A part of every order funds girl-child education through Nanhi Kali.
