Founder Diaries · Club Scenting · Members’ Lounges & Long Dwell
By Sonal Sahani · ISIPCA Versailles 12 min read Updated August 2026
Begin by accepting that nobody is misbehaving. The steward who turns the lounge up has been breathing that fragrance since before the club opened, cannot detect it any more, and is raising the setting because they are conscientious rather than because they are careless. An instruction not to touch it will therefore fail, and it will fail slowly and invisibly, which is the worst way for a control to fail. What works is procedure and hardware: one named person who owns the setting, a written record of what that setting is, a key-lock turned and a key kept with the master keys, a check performed only by walking in from outside, and a log of every change with a date and a name against it. This page is the operating procedure, set out so a house committee can adopt it as written.
Quick answers — read this first
Do not rely on an instruction. “Nobody is to change the diffuser” is an instruction aimed at people who sincerely believe the machine has stopped working. Remove the decision instead of forbidding it.

The four controls, in order of value: one named owner of the setting; a written record of intensity, run window, days and position; the key-lock turned with the key on the master ring; and a scheduled check made from outside the building by a named person.

Close the second route. Vaayu ₹11,999 is controlled by a Bluetooth app as well as by onboard buttons, so the paired handset is part of the control system and belongs to the same named person. Aangan ₹25,999 has no app and no Bluetooth at all — it is programmed at the unit through an intelligent PCB, which for governance is an advantage rather than a limitation.

The honest gap, and it is a real one: no SOSA machine publishes a usage log, a tamper alert, a change history or any remote locking, and there is no BMS, API or dry-contact connection through which a setting could be enforced centrally. The paper record in the duty file is the club’s only audit trail. I would rather say that than let a committee assume the machine is watching itself.

The second gap: the published specification says Vaayu has a key-lock. Exactly what that lock covers is not set out on the page, so if your procedure depends on it, ask before you write the procedure — the contact page is the place.
The short answer
Short answer: make the setting a controlled document rather than a dial. Name one owner, write down the intensity, the run window, the days and the machine position, lock the controls, keep the key with the master keys, and check the room only by walking in from the car park on a fixed day. Every change is recorded with a date and a name, and no change is made on the report of anyone who has been inside the building that day.
Why the instruction alone fails: the person raising the level is acting on an honest observation. They walk the lounge before service, detect nothing, conclude that the machine has failed, and correct it. Each individual step is defensible and the sequence is ruinous, because they adapt to the new level within a day or two and repeat the correction. Six months of that produces a room members call overpowering and a manager who genuinely believes it is discreet. A rule that asks somebody to disbelieve their own nose is a rule that will be broken by the most diligent members of staff first.
The reverse failure, which clubs forget: a member complains that the lounge is too strong, a duty manager turns the machine down or switches it off to settle the moment, and nobody records it. The club now has an unexplained inconsistency, a setting nobody can reconstruct and, often, a machine quietly left off for a season. The same written record prevents both failures, which is why the record is worth more than the lock.
The procedure
How do I keep a club’s scent setting where I put it, when nobody in the building can smell it?
1. Name one owner, in writing, and name them by post rather than by person. The general manager or the house manager owns the fragrance setting the way somebody owns the key press or the cellar book. Naming a post rather than an individual means the ownership survives a resignation. Everybody else — stewards, housekeeping, the duty manager, the contractor who refills the tank — may report, and may not adjust.

2. Write the setting down where the club writes everything else down. Machine, room, position, mounting, intensity setting, run window, selected days, date last changed, name of the person who changed it, and the reason. One sheet in the duty file. A setting held in somebody’s memory has already begun to drift.

3. Turn the key-lock and put the key with the master keys. Vaayu has a key-lock alongside adjustable intensity and auto-stop, and in a club that single feature is worth more than most of the specification. A key in a drawer behind the bar is not a lock. A key on the master ring, signed out, is.

4. Close the second route to the controls. Vaayu is operated by a Bluetooth app as well as by its onboard buttons, so the paired handset is part of the control system and should belong to the named owner rather than to whoever was on shift when it was commissioned. If the club would rather have one route only, Aangan is programmed at the unit through its PCB and has no app and no Bluetooth — and its usual position in a plant area rather than in the lounge puts useful distance between the setting and the floor.

5. Check it on a fixed day, from outside, and record the verdict even when nothing changes. The owner leaves the building, spends a genuine interval in different air and returns through the members’ entrance. The entry in the file reads “checked, no change” far more often than it reads anything else, and that is the point — a procedure that only records interventions cannot show you drift. Everything SOSA makes is alcohol-free, phthalate-free, paraben-free, IFRA-compliant and 0 ppm formaldehyde, composed in Pune, and a portion of every order supports girl-child education through Nanhi Kali.
TL;DR: do not ask staff to resist an honest perception. Take the decision away from them: one named owner, a written setting sheet, the key-lock turned with the key on the master ring, the paired phone in the owner’s hands, and a scheduled walk-in check from outside with every result logged. The lock stops the drift; the record is what proves there was none.
SOSA Vaayu waterless cold-air scent machine
The one feature a club should shop for
Vaayu · key-lock, auto-stop, adjustable intensity ₹11,999
Most of what is written about commercial diffusers concerns coverage. In a members’ club the feature that decides whether the installation still works in a year is the key-lock, because the building is full of people who cannot perceive the fragrance and can reach the buttons. Vaayu offers adjustable intensity, auto-stop and a key-lock, with run windows of 1h / 4h / 8h / 24h and a choice of days, through a Bluetooth app or the onboard buttons. Up to 1000 m³ ≈ 2,000–3,000 sq ft from a sealed residue-free 400ml tank lasting up to about 90+ days depending on intensity and hours, at under 38 dB, on DC 12V / 1A at 5W — a low-voltage point the electrical drawing should show at the mounting position. Freestanding, wall-mounted or into an HVAC return. CE, RoHS and SGS. Black and white.

Why an instruction fails, and what a lock is really doing

A club that has read about nose-blindness usually responds by circulating a note. The note does not work, and it is worth being precise about why, because the reason determines the remedy. An instruction is effective against a person who wants to do the forbidden thing and ineffective against a person who believes the forbidden thing is the right thing. The steward raising the intensity is in the second category. They are not indulging a preference; they are correcting what they sincerely perceive as a fault in a room they are responsible for. Three mechanisms keep that happening, and each needs a different piece of the procedure.

1
MECHANISM ONE · GOOD INTENTIONS
The person changing it is the person who cares most
SOSA Vaayu waterless cold-air scent machineVaayu₹11,999In every club I have worked with, the individual who adjusted the machine was one of the best people on the team. They walk the lounge before service, they notice things, and what they noticed was a room that seemed to have lost its fragrance. Treating that as a discipline problem is both unfair and useless, and it produces the one outcome worse than an over-dosed lounge: a team that stops reporting anything. The productive framing is the opposite. Tell the team explicitly that being unable to smell the fragrance is expected, that it is the reason the club uses an outside check, and that their observations are wanted as reports rather than as corrections. A steward who understands that they are the club’s most adapted instrument is usually rather pleased to be told, and stops reaching for the dial without being forbidden to.
The reverse case, equally common: a manager turns it down or off after one member complains and tells nobody. A written setting makes that visible at the next check instead of six weeks later.
2
MECHANISM TWO · MORE ROUTES THAN YOU THINK
A setting can move without anybody deciding to move it
SOSA Aangan HVAC nebulising diffuserAangan₹25,999List the ways a club’s fragrance setting actually changes and only the first is deliberate. Somebody adjusts the intensity. Somebody adjusts the run window because a function ran late. The unit is unplugged to free a socket for a band or a florist and comes back on without its schedule. The tank is refilled by a contractor who presses buttons to confirm the machine is working. The machine is moved a metre so a sofa can be repositioned, which changes nothing on the display and a great deal in the room. And on an app-controlled unit, anybody with the paired handset can alter the setting without going near the lounge at all. A procedure written only against the first route will be defeated by the other five. The setting sheet should therefore record the position and the mounting as well as the numbers, and refill day should be treated as a scheduled event with a check afterwards.
The governance point for a specifier: fewer routes is a feature. Aangan is programmed at the unit and has no app and no Bluetooth, so the only way to change it is to stand in front of it — which, when the unit sits in a plant area, is a meaningful control in itself.
3
MECHANISM THREE · NO AUDIT TRAIL
The machine will not tell you it was changed, so the paper has to
SOSA Evening Calm reed diffuserEvening Calm₹799This is where I have to be straightforward about a limitation rather than sell around it. No SOSA machine publishes a usage log, a change history, a tamper alert or any form of remote supervision, and there is no Wi-Fi, BMS, API, dry contact, Modbus or BACnet connection on any of them through which a setting could be monitored or enforced from a building system. The mechanical HVAC or AHU connection on Aangan is a genuine integration, but it is ductwork rather than data and it carries no information back. What follows is simple and slightly old-fashioned: the club’s written record is the entire audit trail, and it is only as good as the discipline behind it. There is also no service contract, AMC or scheduled maintenance visit published by SOSA, so no external party is coming to verify the setting on the club’s behalf.
The question to ask before you write the procedure: the published specification states that Vaayu has a key-lock, but not what the lock covers in detail. If your SOP depends on it, ask through the contact page rather than assuming.

The setting sheet, field by field

The document itself should be dull and one page long, and it should live wherever the club already keeps things a duty manager must consult — the duty file, the handover folder, the same place the key press is signed. Ten fields are enough, and the reason each is there is that I have watched a club lose its setting through the absence of it.

Machine and room — which unit, which space, because a club with three zones will otherwise record one and assume the others. Position and mounting — freestanding, wall-mounted or into an HVAC return, with the location described well enough that somebody could put it back. Intensity setting. Run window and selected days — for Vaayu, which of 1h / 4h / 8h / 24h and which days; for Aangan, the programmed work and pause cycle and daily schedule as entered at the unit. Date last changed and name and post of the person who changed it, because a change with no name attached is a change nobody can ask about. Reason for the change, in one line. Date of last check and its verdict, including the checks where nothing was altered. And refill date, since refill day is the most common accidental route to a changed setting.

Two rules govern the sheet. The first is that a change is made only after a walk-in from outside, never in response to a report from inside the building. A report from a steward starts the process; it does not conclude it. The second is a minimum interval between changes — in most clubs, once a quarter is generous, and a fragrance setting altered more often than the wine list is a setting that is drifting rather than being managed. If a change is genuinely needed sooner, it should be because something in the building changed: a refurbishment, a new air-handling regime, a room reconfigured, a door habitually propped open. Those are legitimate reasons, and they belong in the reason field where the next manager can read them.

Who may do what, and how each control is actually enforced

The permissions table a house committee can adopt as written. The final row is the one a supplier ought to volunteer rather than be asked for.

The permissions table
Roles, permitted actions, and what enforces them
Who May do May not do What enforces it
Named owner — GM or house manager ★ Set intensity, schedule and position; authorise every change Change it on a report from inside the building, or without recording it The setting sheet, and a committee that reads it
Duty manager Report, log a member comment, confirm the machine is running Adjust intensity or schedule, even after a complaint Key-lock; key signed out from the master press
Stewards and floor staff Report anything they notice, including that they cannot smell it Touch the controls or move the machine Key-lock, and a team briefed on why they cannot perceive it
Housekeeping and maintenance Clean around the unit; report a moved or unplugged machine Reposition the unit, or leave it unplugged after an event Position recorded on the sheet and checked at each review
Refill contractor Refill the reservoir on a scheduled day Press anything else, or leave without a post-refill check Refill treated as a logged event with a check afterwards
Anyone holding the paired handset Nothing, unless they are the named owner Alter the setting remotely on an app-controlled unit The handset belongs to the owner; or choose a machine with no app
The gap in this table Nothing here is enforced by the machine itself No usage log, change history, tamper alert, remote lock or BMS supervision is published for any SOSA machine Paper, discipline, and a check somebody is actually named for
Specify the control, not just the coverage
The lockable zone machine, the single-route whole-floor machine, and the quiet register
The SOSA principle
A control that depends on somebody distrusting their own senses is not a control. A key, a sheet of paper and a named person are.
Which is why the most useful thing on a commercial diffuser’s specification, for a club, is the lock — and the most useful thing in the club is the record.

The check: from outside, on a fixed day, by somebody named

A procedure without a scheduled check decays into a filing exercise. The check has four properties and each of them is doing work. It is performed by the named owner, so that judgement and authority sit in the same person. It is performed on a fixed day, because a check that happens when somebody remembers is a check that happens after a complaint. It begins outside the building, with a genuine interval in different air rather than a step into the porch, because the fragrance is only perceptible to somebody crossing into it. And it ends with an entry in the file whatever the outcome, because a record that contains only changes cannot demonstrate stability.

What the check should look for is worth stating too, since “does it smell right” is not a usable brief. Walk the route a member walks — from the car park through the threshold, the lobby, the corridor and into the lounge — and ask three questions in order. Is the lounge below the level at which I would name it, given that I have just arrived fresh and am the most sensitive person in the building at this moment? Is the transition from the lobby continuous, or is there a seam where something has been turned up? And does the room smell of fragrance, or does it smell of a room that happens to be pleasant? The third question is the real one, and the answer a club should want is the second.

One more discipline, and it is the one clubs find hardest. When a member complains that the lounge is too strong, the correct immediate response is to record it and thank them, not to reach for the machine. A complaint is exactly the fresh-nose evidence the procedure was designed to collect, and it deserves a proper change made by the owner rather than a panicked adjustment by whoever was on the floor. Equally, when a member says the club smells wonderful, that too belongs in the file, because it is data of the same kind and it usually arrives when the setting is right. The record of unprompted member remarks, kept over a year, is the closest thing a club will ever have to a measurement — and given that no meter, sensor or intensity reading is published or supplied for any SOSA product, it is the instrument you have.

Do not ask your best steward to ignore their own nose. Take the decision out of the lounge altogether, write it down, and put the key on the same ring as the cellar.

The governance edit — and what is not published, stated twice

The whole procedure in the order I would introduce it, with the parts that cost nothing first. The final row names the supervisory features that do not exist rather than allowing a committee paper to assume them.

The setting-governance edit
What to put in place, what not to buy, and what the machine will not do for you
Step What it is Why it works Cost
1. Brief the team on why they cannot smell it ★ Adaptation named openly as expected, universal and not a fault in anybody Converts a correction into a report, which is what you actually want from the floor No cost
2. Name one owner, by post GM or house manager owns the setting the way somebody owns the key press Ownership survives a resignation, and authority sits with the person who checks No cost
3. Write the setting sheet Machine, room, position, mounting, intensity, run window, days, date, name, reason, last check, refill date A setting held in memory drifts within a season; a setting on paper can be audited by a committee No cost
4. Schedule the walk-in check Fixed day, named person, from outside the building, logged whether or not anything changes A check that only records interventions cannot demonstrate stability No cost
5. Turn the key-lock and control the handset Vaayu’s key-lock with the key on the master ring, and the paired phone held by the owner Closes both routes to the controls rather than only the obvious one ₹11,999
6. Where governance matters most, choose fewer routes Aangan is programmed at the unit through its PCB, with no app and no Bluetooth, and usually sits in a plant area The only way to change it is to stand in front of it, which is a control in itself ₹25,999
Do not buy: a replacement machine for a drifted setting Before concluding the unit is underperforming, check the sheet, the position and the tank — the commonest “faulty machine” is a machine somebody adjusted Saves a capital purchase and, more importantly, saves repeating the drift on new hardware Saves ₹11,999
The honest gaps: what the machine will not do No usage log, change history, tamper alert, remote lock or central supervision is published for any SOSA machine, and there is no Wi-Fi, BMS, API, dry contact, Modbus or BACnet route through which a setting could be enforced. What the Vaayu key-lock covers in detail is not set out on the published page. No service contract or AMC is published, so nobody external is checking on the club’s behalf, and no purchasable refill oil is listed for the waterless commercial machines — that fragrance is specified and quoted per property Said plainly, because a procedure written on an assumed feature is a procedure that fails silently Quoted
Honest notes for a house committee: SOSA fragrances are alcohol-free, phthalate-free, paraben-free, IFRA-compliant and 0 ppm formaldehyde, with six fibre reeds in a refillable glass bottle on the reed line, composed in Pune by an ISIPCA Versailles-trained perfumer. Vaayu has the Bluetooth app, onboard buttons, a key-lock, auto-stop and CE, RoHS and SGS marks; Aangan is programmed at the unit through an intelligent PCB with work and pause cycles and daily schedules, and no certifications are published for it.

One route to the setting, and it is not on the floor
Aangan · HVAC nebulising diffuser ₹25,999
For a club where governance is the deciding factor, this machine has a quiet advantage: it is programmed at the unit through an intelligent PCB holding programmable work and pause cycles and daily schedules, with no app and no Bluetooth, and it is normally installed at the air handling rather than in the room. Changing the setting therefore means going to the plant area deliberately, which is a different act from nudging a dial on a console at the end of a long shift. Up to 3,000 m³ ≈ 8,000–10,000 sq ft when connected to HVAC or an AHU, or standalone wall-mounted or laid flat. 800ml reservoir giving weeks between refills on business-hours schedules, under 42 dB, DC 12V at 14W, metal body of 3.9 kg at 284 × 125 × 246 mm, black or white, one-year warranty, imported.

A note from Sonal

I was once shown a lounge that had been set four times in five months, each time by a different and entirely well-meaning person, and each time upward. Nobody had done anything wrong by their own lights. There was no record of any of it, so the club could not even establish where it had started. The committee’s instinct was to ask whether the machine was faulty. The machine was doing precisely what it had been told, four times over.

What struck me was that the club already knew how to solve this problem. It had a key press with a signing-out book. It had a cellar with a stock record and one person answerable for it. It had a procedure for the safe, for the guest book, for the flowers. It simply had not occurred to anyone that a fragrance setting was the same kind of object — a decision that has to be made once, written down and defended — because it looked like a switch rather than like an asset.

So my advice is less perfumery than housekeeping. Treat the setting as a controlled document and the machine as a locked cupboard. Brief the team honestly, because people are far more willing to leave something alone when they understand why their own perception cannot be trusted on it, and nobody likes being told to ignore themselves without a reason. And keep the record even when nothing changes, because the entries that say “checked, no change” are the ones that prove the club is being run properly. Everything we make is composed in Pune, and a part of every order funds a girl’s classroom through Nanhi Kali.

Frequently asked questions

How do I stop staff turning the diffuser up?
Remove the decision rather than forbidding it. Name one owner by post, write the setting down — intensity, run window, days, position, date, name and reason — turn the key-lock on the machine and keep the key with the master keys, hold the paired handset yourself on an app-controlled unit, and check the room on a fixed day by walking in from outside. Then brief the team that being unable to smell the fragrance is expected and that their observations are wanted as reports rather than as corrections. An instruction alone fails because the person adjusting it sincerely believes the machine has stopped working.
Does the Vaayu key-lock stop everything?
The published specification states that Vaayu has a key-lock alongside adjustable intensity and auto-stop, and in a club it is the single most useful feature on the machine. What the lock covers in detail is not set out on that page, so if your written procedure depends on it, ask before you rely on it rather than after — the contact page is the right place. Remember also that the machine is operated by a Bluetooth app as well as by its onboard buttons, so the paired handset is part of the control system and should sit with the named owner.
Can we lock or monitor the setting from the club’s building management system?
No. There is no Wi-Fi, BMS, API, dry contact, Modbus, BACnet, KNX, Crestron or Control4 connection on any SOSA machine, and none of them publishes a usage log, change history or tamper alert, so a setting cannot be supervised or enforced centrally. What does exist is a real mechanical integration — Aangan connects to an HVAC or AHU so the building’s own air carries the fragrance — but that is ductwork rather than data and it reports nothing back. The club’s written record is the audit trail, which is why the sheet matters more than the lock.
A member said the lounge is too strong. Should the duty manager turn it down?
Record it and thank them, then let the named owner make the change after a walk-in check. A complaint from a member is the best evidence the club will ever collect, because it comes from an unadapted nose, and it deserves a considered adjustment rather than an improvised one that nobody writes down. The reverse failure is just as damaging as creeping upward: an unrecorded reduction, or a machine quietly switched off to settle a moment, leaves the club with an inconsistency nobody can reconstruct. Both are prevented by the same sheet of paper.
How often should the setting be reviewed?
Check on a fixed schedule and change rarely. In most clubs a quarterly review is generous, and a fragrance setting altered more often than the wine list is drifting rather than being managed. Change it sooner only when something in the building has genuinely changed — a refurbishment, a new air-handling regime, a room reconfigured, a door now habitually propped open — and record that reason on the sheet. Note that no service contract, AMC or maintenance visit is published by SOSA, so nobody is coming to do this for you; the review is the club’s own.

The procedural recommendations here are editorial guidance rather than a contractual specification, and the perfumery and sensory reasoning is explanation rather than a laboratory claim about any specific test. No adaptation time in minutes, concentration threshold, in-room intensity reading, consumption rate or machine count as a formula is published for any SOSA product, and SOSA supplies no sensor or meter; no SOSA machine publishes a usage log, change history, tamper alert or remote supervision, and the scope of the Vaayu key-lock is not detailed on the published page.

Hotel Collection fragrance oils are water-based and ultrasonic-only at 15ml ₹299, 100ml ₹999 and 300ml ₹1,799, taking three to six drops in the water tank; they are not for reed diffusers and not for the waterless commercial machines. No purchasable refill oil is listed for the waterless commercial machines; that fragrance is specified and quoted per property. SOSA publishes no leather fragrance in any format and no tobacco or smoky fragrance for any diffuser. SOSA sells no air purifier and no dehumidifier, and every SOSA spray is a car perfume rather than an interior product. No SOSA machine offers Wi-Fi, Alexa, Google Assistant, KNX, Crestron, Control4, Modbus, BACnet, an API, a dry contact or any building-management integration; the Aangan HVAC connection is mechanical. No dealer programme, reseller margin, trade price, territory, service contract or AMC is published. Reed diffusers 50ml ₹749–₹849 lasting 6–8 weeks and 130ml ₹1,249–₹1,349 lasting 14–18 weeks, six fibre reeds, alcohol-free, phthalate-free, paraben-free, IFRA-compliant, 0 ppm formaldehyde, heat-stable CCT carrier, refillable glass bottle, tested at 45°C and 85% RH, composed in Pune. Free shipping above ₹499. A portion of every order supports girl-child education through Nanhi Kali.
