The question that sorts suppliers fastest: ask what they need from you before they can size the job. A supplier who asks for connected volume, ceiling heights, door positions, how many air handling systems serve the property and how many hours each zone is occupied is working properly. A supplier who gives you a machine count over the phone has not asked enough to be right.
The five questions SOSA cannot answer from a published page: the consumption rate in millilitres per hour; what a year of fragrance will cost for your particular volume; what certification the larger machines carry; whether there is a purchasable refill SKU for the waterless range; and what the service arrangement is, since no annual maintenance contract or installation charge is published.
What is firmly answerable: Vaayu ₹11,999, up to 1000 m³ ≈ 2,000–3,000 sq ft, 400ml tank up to about 90+ days, under 38 dB, DC 12V / 1A at 5W, key-lock, CE, RoHS and SGS. Aangan ₹25,999, up to 3,000 m³ ≈ 8,000–10,000 sq ft on HVAC, 800ml, under 42 dB, DC 12V at 14W, programmable cycles. Meenar ₹38,500, the larger-property option, specified on enquiry.
The honest gap: no purchasable refill oil is listed for the waterless commercial machines, so the fragrance line is specified and quoted per property through the contact page. Ask every supplier the same question and compare the answers.
Aangan₹25,999What is the connected volume, not the floor area. Which spaces open into one another with no door between them, and what are the ceiling heights across them. Where does the air in that volume go. How many air handling systems serve the property, whether the zones you want scented are actually on the same one, and whether there are lift shafts or open staircases connecting floors — because those behave as chimneys, carrying warm air and fragrance to floors nobody intended to scent. How long does a member stay. A space you walk through and a space you sit still in need different doses, and the mistake is almost always to set the sitting space at the walking-through level. What are the operating hours, by zone. What is already in the building — carpet, underlay, heavy curtains, upholstery, timber panelling, all of which absorb odour and release it later. And does the building currently smell of anything, because if the answer is a heavy, closed note in the morning, that is moisture and air change rather than a fragrance deficit, and the order of work is source, moisture, ventilation, cleaning, and only then fragrance.
Vaayu₹11,999Ask these as a written list and expect written answers. What mechanism is it — passive, ultrasonic or waterless nebulising — and if ultrasonic, say plainly that you are in an Indian club where added humidity is usually the enemy. What is the published coverage, in m³. What are the mounting options, and can it go into an HVAC return rather than being an object in the room. What is the electrical requirement at the mounting position, because that is a point on a drawing and a trivially cheap provision before a wall closes. What is the noise figure, which decides whether it can sit near a reading room. What is the reservoir size, and is the tank sealed and residue-free — that last one matters more in a commercial install than it sounds, because it is what makes a machine safe to mount near joinery, electronics and an AC return. How is intensity set, how fine is the schedule, and can the setting be locked. What certification does this specific unit carry — ask per unit, not per range.
Ask usContactWhat is the capital cost, per unit, published. What is the consumable cost, and is that a published price or an estimate — insist on the distinction being said out loud. Is there a refill product with a price and a size, or is the fragrance supplied against a quotation. What does the warranty cover and for how long. What is the arrangement when a unit needs attention, and is there a published service contract — if a supplier quotes you an annual figure, ask what is inside it, because no such figure is published here. Who sets the intensity, who may not change it, and how is the agreed setting recorded. And the question almost nobody asks: what would make you tell me not to buy this. A supplier who cannot name a room they would leave unscented, or a building condition they would fix first, has not thought about your property.

A general manager walking into a scenting meeting is at a structural disadvantage, and it has nothing to do with expertise. The supplier has the numbers, the sample bottles and the vocabulary, and the manager has a floor plan and a committee that will ask about the running cost. The fastest way to close that gap is a written list of questions, taken into the room and worked through in order. What follows is the list I would want a club to bring to me — thirty-odd questions grouped into five areas, with a note on what a straight answer sounds like. It includes five questions that SOSA’s own published pages cannot answer, and I have named which five and why, because a supplier telling you where its own documentation stops is more useful to you than a supplier who answers everything smoothly.
Quick answers — read this first
The five areas to ask about: the building (volume, ceiling heights, air system, hours), the machine (coverage rating, mounting, power, noise, control, lock), the fragrance (what carrier, what register, what happens at low dose), the money (capital, consumable, what is published and what is quoted), and the operation (who sets it, who may not change it, what happens when it needs attention).The question that sorts suppliers fastest: ask what they need from you before they can size the job. A supplier who asks for connected volume, ceiling heights, door positions, how many air handling systems serve the property and how many hours each zone is occupied is working properly. A supplier who gives you a machine count over the phone has not asked enough to be right.
The five questions SOSA cannot answer from a published page: the consumption rate in millilitres per hour; what a year of fragrance will cost for your particular volume; what certification the larger machines carry; whether there is a purchasable refill SKU for the waterless range; and what the service arrangement is, since no annual maintenance contract or installation charge is published.
What is firmly answerable: Vaayu ₹11,999, up to 1000 m³ ≈ 2,000–3,000 sq ft, 400ml tank up to about 90+ days, under 38 dB, DC 12V / 1A at 5W, key-lock, CE, RoHS and SGS. Aangan ₹25,999, up to 3,000 m³ ≈ 8,000–10,000 sq ft on HVAC, 800ml, under 42 dB, DC 12V at 14W, programmable cycles. Meenar ₹38,500, the larger-property option, specified on enquiry.
The honest gap: no purchasable refill oil is listed for the waterless commercial machines, so the fragrance line is specified and quoted per property through the contact page. Ask every supplier the same question and compare the answers.
The short answer
Short answer: ask about the building before the bottle. The three questions that decide whether a scenting scheme works are the connected volume you are trying to fill, where the air in that volume actually goes, and how long a member sits in it — and none of those is on a spec sheet. After that, ask the machine questions in writing: published coverage in m³ rather than sq ft, mounting options including an HVAC return, the low-voltage requirement, the noise figure, how intensity is set and whether the setting can be locked.
Then ask the uncomfortable ones. What is the consumption rate in millilitres per hour. What will a year of fragrance cost for my volume at the setting you are recommending. What certifications does each machine in the range carry, individually. Is there a refill product I can order with a price on it. And what happens in eighteen months when something needs attention. A supplier who answers all five instantly and precisely is either unusually well documented or guessing, and it is worth knowing which.
Specify: Vaayu ₹11,999 — up to 1000 m³ ≈ 2,000–3,000 sq ft, 400ml refillable sealed tank running up to about 90+ days depending on intensity and hours, under 38 dB, DC 12V / 1A at 5W, freestanding, wall-mounted or into an HVAC return, Bluetooth app plus onboard buttons, run windows of 1h / 4h / 8h / 24h, day selection, adjustable intensity, auto-stop and key-lock, CE, RoHS and SGS, black or white. Aangan ₹25,999 — up to 3,000 m³ ≈ 8,000–10,000 sq ft on HVAC or standalone, 800ml reservoir, under 42 dB, DC 12V at 14W, intelligent PCB with programmable work and pause cycles and daily schedules, metal body 3.9 kg at 284 × 125 × 246 mm, one-year warranty, imported. Free shipping above ₹499.

Straight answer
What should a club general manager actually ask a scenting supplier before signing anything?
1. Start with what the supplier needs from you, not with what they are selling. The opening question is simply: what do you need to know about my building before you can tell me what it needs. A supplier working properly will ask for connected volume rather than floor area, for ceiling heights where they are not standard, for where the closed doors are, for how many air handling systems serve the property, and for how many hours each zone is genuinely occupied. If a machine count arrives before those questions do, the number is a guess with a decimal point on it. Coverage is published in m³ for a reason: a double-height lobby or a galleried stair consumes coverage that a square-foot figure hides entirely.
2. Ask the machine questions in writing, and ask them as a list. Published coverage, and in what unit. Mounting options, specifically whether it can go into an HVAC return rather than onto a wall. The electrical requirement, because that is a point on a drawing — Vaayu is DC 12V / 1A at 5W and Aangan is DC 12V at 14W. The noise figure, under 38 dB and under 42 dB respectively, which matters in a quiet reading room. Reservoir size, 400ml and 800ml. How intensity is adjusted, how a schedule is set, and — the question clubs forget — whether the setting can be locked.
3. Ask what the fragrance physically is, and what it does when it is quiet. The carrier decides the machine, so ask whether the oil is water-based or neat, because they are not interchangeable in either direction. Then ask the question that separates a perfumer from a reseller: what happens to this composition at a very low dose. A fragrance dosed low is mostly its heart and base, because the top notes are the first thing lost, so a composition chosen at full strength from a blotter at a committee table can be unrecognisable as a thin vapour across a lounge four hours later. Dry, structured registers — tea, cedar, vetiver, bergamot — keep their outline when quiet. Sweet and powdery ones lose their shape and read as a vague smell of perfume.
4. Separate what is published from what is quoted, and write both into the paper. Capital is published to the rupee: ₹11,999, ₹25,999 and ₹38,500. The fragrance line is not, because SOSA lists no purchasable refill oil for the waterless commercial machines and publishes no consumption rate, and any figure printed for it would be invented. Ask any supplier the same question and insist on hearing which half of their answer is a published price and which is an estimate. An estimate is perfectly acceptable. An estimate presented as a price is not.
5. Ask who will own the setting after you have gone home. This is the question that decides whether the scheme survives its second year. Ask who sets the intensity, who is forbidden to change it, how the agreed setting is recorded, and how it will be checked. The person who sets a level is the one person in the building who has stopped being able to judge it, because the nose reports change rather than constancy. So the procedure is: set it once, lock it, write it down, and audit it only by walking in from the car park with somebody who has been outside. Everything SOSA makes is alcohol-free, phthalate-free, paraben-free, IFRA-compliant and 0 ppm formaldehyde, composed in Pune, with free shipping above ₹499 and a portion of every order supporting girl-child education through Nanhi Kali.
2. Ask the machine questions in writing, and ask them as a list. Published coverage, and in what unit. Mounting options, specifically whether it can go into an HVAC return rather than onto a wall. The electrical requirement, because that is a point on a drawing — Vaayu is DC 12V / 1A at 5W and Aangan is DC 12V at 14W. The noise figure, under 38 dB and under 42 dB respectively, which matters in a quiet reading room. Reservoir size, 400ml and 800ml. How intensity is adjusted, how a schedule is set, and — the question clubs forget — whether the setting can be locked.
3. Ask what the fragrance physically is, and what it does when it is quiet.

Then ask the question that separates a perfumer from a reseller: what happens to this composition at a very low dose.

Dry, structured registers — tea, cedar, vetiver, bergamot — keep their outline when quiet. Sweet and powdery ones lose their shape and read as a vague smell of perfume.
4. Separate what is published from what is quoted, and write both into the paper. Capital is published to the rupee: ₹11,999, ₹25,999 and ₹38,500. The fragrance line is not, because SOSA lists no purchasable refill oil for the waterless commercial machines and publishes no consumption rate, and any figure printed for it would be invented. Ask any supplier the same question and insist on hearing which half of their answer is a published price and which is an estimate. An estimate is perfectly acceptable. An estimate presented as a price is not.

TL;DR: ask what the supplier needs from you first; then coverage in m³, mounting including HVAC return, the low-voltage point, noise, reservoir, schedule granularity and whether the setting locks; then what the oil does at low dose; then which figures are published and which are quoted; then who owns the setting afterwards. Five of those questions have no published answer here, and they are listed by name below.
The machine with the fullest answer sheet
Vaayu · waterless cold-air nebuliser ₹11,999
If you work down a question list, this is the unit that answers most of it from a published page. Coverage up to 1000 m³, roughly 2,000–3,000 sq ft at ordinary ceiling height. Mounting freestanding, wall-mounted, or into an HVAC return. Power DC 12V / 1A at 5W, which is the figure to give an electrical consultant. Under 38 dB. A sealed, residue-free 400ml tank running up to about 90+ days depending on intensity and hours. Control by Bluetooth app or the onboard buttons, with run windows of 1h, 4h, 8h and 24h, day selection and adjustable intensity. Auto-stop and a key-lock, which is the single most useful club feature in the range. CE, RoHS and SGS. Black or white.
The three groups of questions, in the order to ask them
Order matters more than completeness here. A manager who asks about fragrance before asking about air will have a pleasant conversation and buy the wrong size of machine. Building, then hardware, then commerce — and the third group only makes sense once the first two have produced a scheme.
1
GROUP ONE · THE BUILDING
Six questions that have to be answered before any machine is named
Aangan₹25,999What is the connected volume, not the floor area. Which spaces open into one another with no door between them, and what are the ceiling heights across them. Where does the air in that volume go. How many air handling systems serve the property, whether the zones you want scented are actually on the same one, and whether there are lift shafts or open staircases connecting floors — because those behave as chimneys, carrying warm air and fragrance to floors nobody intended to scent. How long does a member stay. A space you walk through and a space you sit still in need different doses, and the mistake is almost always to set the sitting space at the walking-through level. What are the operating hours, by zone. What is already in the building — carpet, underlay, heavy curtains, upholstery, timber panelling, all of which absorb odour and release it later. And does the building currently smell of anything, because if the answer is a heavy, closed note in the morning, that is moisture and air change rather than a fragrance deficit, and the order of work is source, moisture, ventilation, cleaning, and only then fragrance.
The specifiable fact: coverage is published in volume, not floor area — up to 1000 m³ for Vaayu and up to 3,000 m³ for Aangan when it is connected to the HVAC or AHU. A closed door is a real boundary, so two small rooms with a door between them are two zones however modest their combined area.
2
GROUP TWO · THE HARDWARE
The spec-sheet questions, which should all have one-line answers
Vaayu₹11,999Ask these as a written list and expect written answers. What mechanism is it — passive, ultrasonic or waterless nebulising — and if ultrasonic, say plainly that you are in an Indian club where added humidity is usually the enemy. What is the published coverage, in m³. What are the mounting options, and can it go into an HVAC return rather than being an object in the room. What is the electrical requirement at the mounting position, because that is a point on a drawing and a trivially cheap provision before a wall closes. What is the noise figure, which decides whether it can sit near a reading room. What is the reservoir size, and is the tank sealed and residue-free — that last one matters more in a commercial install than it sounds, because it is what makes a machine safe to mount near joinery, electronics and an AC return. How is intensity set, how fine is the schedule, and can the setting be locked. What certification does this specific unit carry — ask per unit, not per range.
The specifiable fact: CE, RoHS and SGS are published for Vaayu. For the two larger machines no certification is published at all, and a supplier should say so rather than let a range-level claim cover every unit in it.
3
GROUP THREE · THE COMMERCE
Money, ownership and what happens in year two
Ask usContactWhat is the capital cost, per unit, published. What is the consumable cost, and is that a published price or an estimate — insist on the distinction being said out loud. Is there a refill product with a price and a size, or is the fragrance supplied against a quotation. What does the warranty cover and for how long. What is the arrangement when a unit needs attention, and is there a published service contract — if a supplier quotes you an annual figure, ask what is inside it, because no such figure is published here. Who sets the intensity, who may not change it, and how is the agreed setting recorded. And the question almost nobody asks: what would make you tell me not to buy this. A supplier who cannot name a room they would leave unscented, or a building condition they would fix first, has not thought about your property.
The honest gap: SOSA publishes no dealer programme, reseller margin, trade price, territory, minimum order, lead time, installation charge or annual maintenance figure, because none exists. Commercial enquiries are answered individually through the contact page, which is an invitation to ask rather than a promise of terms.
The question sheet, with what a straight answer sounds like
Print this, take it in, and write the answers in the third column as they are given. The value is not in any single row; it is in seeing, at the end of the meeting, how many rows are filled with a figure and how many are filled with a reassurance.
The club manager’s question sheet
What to ask, why you are asking, and what a straight answer sounds like
| The question | Why you are asking it | What a straight answer sounds like |
|---|---|---|
| What do you need from me before you can size this ★ | It sorts a specifier from a seller in one answer | Connected volume, ceiling heights, door positions, how many air systems, occupied hours per zone |
| What is the published coverage, and in what unit | A sq ft figure hides a double-height lobby entirely | Stated in m³, with the sq ft equivalent given as an approximation at ordinary ceiling height |
| Can it go into an HVAC return | It is how a fragrance source becomes unfindable | A clear yes or no, and for Aangan a description of the mechanical AHU connection |
| What is the electrical requirement at the position | It is a point on a drawing, and free to provide before a wall closes | DC 12V / 1A at 5W for Vaayu, DC 12V at 14W for Aangan |
| What is the noise figure | A quiet reading room will hear a compressor | Under 38 dB and under 42 dB, as published figures rather than “silent” |
| Is the tank sealed and residue-free | It decides whether the unit can sit near joinery and electronics | Yes for the waterless range, with no water and therefore no mineral residue |
| Can the setting be locked | Because the night steward will otherwise turn it up | Vaayu has a key-lock and an auto-stop; the agreed setting should also be written down |
| How fine is the schedule | All-day evenness is a scheduling problem, not an intensity one | Run windows of 1h, 4h, 8h and 24h with day selection on Vaayu; programmable work and pause cycles with daily schedules on Aangan |
| Is the oil water-based or neat | The carrier decides the machine, in both directions | Neat for the waterless range; the water-based Hotel Collection oils are for ultrasonic machines only |
| What does this composition do at a very low dose | A lounge is dosed below naming level, so the quiet version is the one you are buying | Dry structured registers hold their outline; sweet and powdery ones lose shape |
| What is the consumption rate in ml per hour | It is the only honest route to a running figure | Not published here. The honest answer is to measure one zone in your building |
| Is there a refill product with a price | A published SKU and a quotation are different commercial objects | For reeds, yes — 300ml ₹2,399 and 500ml ₹3,499. For the waterless machines, no listed refill product |
| What certification does this unit carry | Range-level claims hide unit-level gaps | CE, RoHS and SGS for Vaayu; nothing published for the two larger units, said plainly |
| What does the warranty cover | It is the only published after-sale commitment | One year on Aangan, stated as such, with no service contract claimed beyond it |
| Which rooms would you tell me not to scent | A supplier who names none has not read your floor plan | Dining and bar counters, spa treatment rooms, the gym floor, boardrooms and a heritage library |

The SOSA principle
A scenting scheme is only a system when it is written down — fragrance, position, intensity, schedule, refill cadence, the unscented list, and one named person who owns it.
Everything on the question sheet above is really an attempt to produce that document. A meeting that ends with a quotation and no written setting has produced a purchase rather than a scheme.
The five questions our own pages cannot answer
Here is the part of this page I would rather a competitor had not written first. Five of the questions above cannot be answered from any SOSA published page, and a club manager working down a list deserves to know which ones before the meeting rather than during it. Naming them is not a disclaimer. It is the information you came for.
What is the consumption rate in millilitres per hour. No figure is published for any machine in the waterless range. It is a real number and your building has one, but it is a function of the intensity you settle on and the hours you schedule, and those are decided by your ceiling heights, your air change and your opening times rather than by the machine. What is published is a life claim rather than a rate: a Vaayu 400ml tank runs up to about 90+ days depending on intensity and hours, and Aangan is described as weeks between refills on business-hours schedules. Those are useful for planning a steward’s round. They are not a rate, and anyone converting them into one is inventing arithmetic.
What will a year of fragrance cost for my volume. This follows directly from the first, and the honest answer is that it cannot be completed from published data and should not be guessed in a meeting. What can be done is to measure it. Run one zone at the fixed setting you intend to live with, for a measured period, and record what the reservoir actually consumed. That gives you your building’s number, at your intensity, on your hours, and it is worth more than any supplier’s estimate. The method is set out on the monthly cost page.
What certification do the larger machines carry. CE, RoHS and SGS are published for Vaayu. For the two larger units nothing is published, and that is the accurate answer rather than an inherited range claim. If a certificate matters to your committee — and in some clubs it does, for insurance reasons — ask for it in writing per unit and route the question through the contact page rather than accepting a brochure line. Is there a published refill SKU for the waterless machines. No. The product pages describe HVAC-grade oil supplied in bulk with a standing-order option, but no refill product is listed and no price for one is published, so the fragrance is specified and quoted per property. And what happens at service. There is a one-year warranty on Aangan. Beyond that no annual maintenance contract, no installation charge and no service agreement is published, because none exists, and a club should not sign a paper that assumes one.
Ask every supplier which half of their running figure is a published price and which half is an estimate. An estimate is fine. An estimate presented as a price is the thing that goes wrong in year two.
— Sonal Sahani, SOSA
The questions to ask after the machine is in
Procurement does not end at delivery, and the three questions below are the ones a club will wish it had asked in the first meeting. They are in the table in buying order, and the last row is the gap again, because it belongs in the paper rather than in a footnote.
The commissioning questions
What to agree before the first setting is made, and what stays quoted
| Step | The question to settle | Why it belongs here | Cost |
|---|---|---|---|
| 1. Is the building ready ★ | Air change before opening, dried carpets, serviced drain traps, humidity down | Fragrance over a closed, damp note produces a mixture members read as concealment | No purchase |
| 2. Which rooms are we not scenting | Dining, private dining and bar counters, spa treatment rooms, the gym floor, boardrooms, a heritage library | Agreeing the exclusions in the first meeting is what makes the rest of the scheme credible to a chef and to a long-standing member | No purchase |
| 3. Who sets the intensity, and who may not change it | One named person, a written setting, and a key-lock turned afterwards | The person in the building all day is the one person who has stopped being able to judge the level | Included |
| 4. How will we test it | By walking in from the car park, with somebody who has been outside, on a written schedule | You cannot judge a room you are standing in, and a visitor is a better instrument than a manager | No purchase |
| 5. What is the refill round | Who tops up which reservoir, how often, and who records that they did | A 400ml tank at up to about 90+ days and an 800ml reservoir at weeks per fill are a rota, not a crisis | Quoted |
| 6. What is written down at the end | Fragrance, position, intensity, schedule, refill cadence, the unscented list, one owner | Without that document the scheme reverts to whoever last touched the dial | No purchase |
| The gap, named: ask us | No consumption rate, no refill SKU, no annual maintenance figure and no certification for the two larger units is published — and SOSA publishes no leather, tobacco or smoky fragrance for any diffuser either | Listed here so a committee paper can carry the gap honestly rather than leave a blank nobody notices until year two | Quoted |
Honest notes for a house committee: every SOSA fragrance is alcohol-free, phthalate-free, paraben-free, IFRA-compliant and 0 ppm formaldehyde; reed diffusers ship with six fibre reeds in a refillable glass bottle and everything is composed in Pune by an ISIPCA Versailles-trained perfumer. The Hotel Collection fragrance oils are water-based and go only into an ultrasonic machine — they are not for reed diffusers and not for the waterless commercial machines. The connection to an air handling unit is a mechanical integration and a real one; there is no digital integration of any kind on any SOSA machine, no building-management interface and no automation protocol, and that is better said in the first meeting than discovered at commissioning. No dealer programme, reseller margin, trade price, territory, minimum order or service contract is published, and no stock figure; commercial enquiries are answered individually through the contact page. Free shipping above ₹499, and a portion of every order supports girl-child education through Nanhi Kali. SOSA is an independent Indian fragrance house and is not affiliated with any hotel brand.
The unit to ask the most questions about
Aangan · HVAC nebulising diffuser ₹25,999
Rated to up to 3,000 m³ — roughly 8,000–10,000 sq ft — when it is connected into the HVAC or air handling unit, and it will also wall-mount or lay flat as a standalone unit. An 800ml reservoir, under 42 dB, DC 12V at 14W, a metal body of 3.9 kg measuring 284 × 125 × 246 mm, black or white, one-year warranty, imported. Control is an intelligent PCB with programmable work and pause cycles, daily schedules and an intensity setting — a board rather than a phone, which in a club is usually an advantage. Two things to ask about specifically: the AHU connection is mechanical rather than digital, and no certification is published for this unit, unlike Vaayu.

A note from Sonal
The best meeting I have had with a club was the one I came out of having sold less than I walked in expecting to. The general manager had a single sheet of paper with nineteen questions on it, numbered, and he went through them in order and wrote my answers in the margin. Four of them I could not answer from a published page, and he wrote that down too, in the same handwriting, without any suggestion that it was a failing. By the end we had agreed two machines instead of four, a list of three rooms we would not touch, and a measurement exercise to establish his own consumption figure before he committed to a fragrance budget.
What made that meeting work was that his questions were about his building and mine were about his building, and neither of us spent any time on which scent was loveliest. A fragrance judged from a bottle or a blotter across a committee-room table tells you almost nothing about how it will behave as a thin vapour across a large volume four hours later. The only honest test is in the room, at the dose you will live with, judged by someone walking in from outside.
So if you take one thing from this page, take the habit of asking which half of each answer is published. We publish a great deal — coverage in m³, mounting options, the low-voltage point, decibels, reservoir sizes, schedule granularity, the key-lock, the certifications on Vaayu, and the full reed line including refills. We do not publish a consumption rate, a refill SKU for the waterless machines, a certificate for the two larger units or any maintenance figure, and I would rather you read that here than extract it from me in a third meeting. Everything we make is composed in Pune, and a part of every order funds a girl’s classroom through Nanhi Kali.
Frequently asked questions
What is the single most useful question to ask a scenting supplier?
Ask what they need from you before they can size the job. A supplier working properly will want connected volume rather than floor area, ceiling heights where they are not standard, where the closed doors are, how many air handling systems serve the property, and how many hours each zone is genuinely occupied. If a machine count arrives before those questions are asked, it is a guess. As reference points, Vaayu is rated to up to 1000 m³ per unit and Aangan to up to 3,000 m³ on HVAC, and no machine count is published as a formula.
How do I ask about running cost in a way that gets a useful answer?
Ask for the consumption rate in millilitres per hour at the intensity being recommended, and then ask whether that figure is published or estimated. For the SOSA waterless range no consumption rate is published and no refill oil is listed as a purchasable product, so the fragrance line is specified and quoted per property rather than priced on a page. What is published is a life claim: a 400ml Vaayu tank runs up to about 90+ days depending on intensity and hours. The way to get a real number is to run one zone at a fixed setting for a measured period and record what it used.
Should I ask about smart-home or building-management integration?
Ask, and expect a clear distinction in the answer. The connection to an air handling unit on Aangan is a mechanical integration and a genuine one — the machine introduces its mist into air the building is already moving. There is no digital integration on any SOSA machine: no building-management interface, no automation protocol and no smart-home connection of any kind. Vaayu has a Bluetooth app and onboard buttons; Aangan is a programmable board with work and pause cycles and daily schedules, and has no app. That distinction is much better established in the first meeting than at commissioning.
What should I ask about certification?
Ask per unit rather than per range, because range-level claims are where gaps hide. CE, RoHS and SGS are published for Vaayu. For the two larger machines no certification is published, and a supplier should tell you that plainly rather than let the Vaayu certificates imply coverage of the whole range. If a certificate matters to your insurer, ask for it in writing for the specific unit you are buying and send the question to the contact page rather than relying on a brochure line.
Is there a question that should make me walk away?
Not a question so much as an answer. If a supplier cannot name a single room in your club they would leave unscented, they have not read your floor plan. Dining rooms, private dining and bar counters should stay neutral, because ambient fragrance competes with the kitchen and flattens wine. So should spa treatment rooms, gym floors, boardrooms and a heritage library whose smell of paper and timber is part of what the membership buys. The other answer to be wary of is a promise that fragrance will fix a musty building, because musty is moisture, air change and absorbent soft furnishings, and fragrance laid over it reads as a cover-up.
Club scenting · the buyer’s question sheet
Ask about the building before the bottle, then ask which half of every figure is published and which half is quoted
Vaayu ₹11,999 covers up to 1000 m³ ≈ 2,000–3,000 sq ft with a 400ml tank lasting up to about 90+ days, under 38 dB, a DC 12V / 1A 5W low-voltage point, a key-lock, and CE, RoHS and SGS. Aangan ₹25,999 covers up to 3,000 m³ ≈ 8,000–10,000 sq ft on HVAC with an 800ml reservoir, programmable schedules and a one-year warranty. Meenar ₹38,500 is the larger-property option, specified on enquiry. No consumption rate and no refill SKU is published for the waterless range, so the fragrance line is quoted per property. Free shipping above ₹499, and a portion of every order supports girl-child education through Nanhi Kali.
