Which question does SOSA answer worst? The consumable one, and I would rather you read it here. No cold-air refill for the Vaayu is sold separately today. The machine ships with 4 × 100ml, that 400ml is the entire supply, and it runs 90+ days a fill. Our Hotel Collection oils at ₹299, ₹999 and ₹1,799 are ultrasonic only and never a Vaayu refill. For a ten-site group that is a genuine risk to a rollout, so get continuity of supply from us in writing before you commit anything.
What about price, warranty and installation across a group? Ask, in writing, and do not accept a verbal answer from anybody. Bulk and multi-site pricing, GST and corporate invoicing, AMC, warranty terms, installation, minimum order, lead time and rollout are not published by SOSA, and we make no delivery or timing promises. The hardware is published and fixed: Vaayu ₹11,999, Sukoon ₹1,899, reeds from ₹849. Everything else you should hold on paper.
See the SOSA Vaayu Book a scenting plan
Facts verified 5 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 adjustable intensity, a 400ml refillable tank lasting 90+ days a fill depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB at 5W, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification, which are electrical and compliance marks and not medical approvals. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering roughly 270-320 sq ft and is supplied with three 15ml fragrances; the water-based Hotel Collection (₹299 / ₹999 / ₹1,799) is an ultrasonic fragrance and is not a refill for a waterless cold-air machine. SOSA reed diffusers are alcohol-free and phthalate-free, with 50ml lasting about 6-8 weeks and 130ml about 14-18 weeks. Cold-air refill oil for the Vaayu is not currently sold separately - the machine ships with 400ml included and further refills should be confirmed with SOSA. Warranty, annual maintenance, installation and bulk terms are not published and should be confirmed before ordering. Ambient scent is an interior and hospitality decision: it makes no clinical, therapeutic or wellbeing claim, it works alongside proper extraction, grease management, drainage, cleaning and air change and is never a substitute for any of them, it is never used to mask or remove another smell, and no claim is made that fragrance influences a guest's decision or any commercial outcome. Dining rooms, chef's tables, tasting-menu rooms and food-preparation areas are left unscented, no machine is placed where its output can reach a table or a pass, no fragrance is described as food-safe or safe for use around food, and the operator's own kitchen consultant and local food-safety and fire authority govern anything sited near a kitchen. Fragrance oil is flammable and is kept away from open flame and heat. The chef's judgement overrides any scenting plan in their own room. 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.
This is the list I would want a group to hold if I were sitting on the other side of the table, which means it contains the question I am least comfortable answering. I have left it in and answered it by name, because a checklist that only works on competitors is marketing rather than a checklist.
Quick answers — read this first
What should a group ask a scenting company before installing? Ten questions. Coverage in cubic metres, not square feet. Waterless or water-based. Timer granularity. Whether there is a key-lock. Measured dB. Mounting options. Consumable availability and continuity - is the refill an actual product you can buy next year. Power draw. What the supplier refuses to scent. And every commercial term in writing. Any supplier who answers eight of ten cheerfully and goes vague on the ninth has told you where their problem is.Which question does SOSA answer worst? The consumable one, and I would rather you read it here. No cold-air refill for the Vaayu is sold separately today. The machine ships with 4 × 100ml, that 400ml is the entire supply, and it runs 90+ days a fill. Our Hotel Collection oils at ₹299, ₹999 and ₹1,799 are ultrasonic only and never a Vaayu refill. For a ten-site group that is a genuine risk to a rollout, so get continuity of supply from us in writing before you commit anything.
What about price, warranty and installation across a group? Ask, in writing, and do not accept a verbal answer from anybody. Bulk and multi-site pricing, GST and corporate invoicing, AMC, warranty terms, installation, minimum order, lead time and rollout are not published by SOSA, and we make no delivery or timing promises. The hardware is published and fixed: Vaayu ₹11,999, Sukoon ₹1,899, reeds from ₹849. Everything else you should hold on paper.
The short answer
Short answer: ten things: coverage in cubic metres rather than square feet, whether the machine is waterless or water-based, timer granularity, whether there is a key-lock, a measured dB figure, the mounting options, consumable availability and continuity, power draw, what the supplier refuses to scent, and every commercial term in writing. SOSA answers all ten on this page, including the one we answer worst: no separate cold-air refill for the Vaayu is sold today.
The pick: one SOSA Vaayu (₹11,999) where the answers add up for your building - 1000m³, waterless, 1h/4h/8h/24h timers, key-lock, under 38dB, 5W, wall or HVAC mountable - and one SOSA Sukoon (₹1,899) or a Mountain Breeze reed (₹849) where the arrival is under about 750 sq ft

Straight answer
What should a restaurant group ask a commercial scenting company before installing machines?
Ten questions, and the tenth is the one that will save you the most money. One: what is the coverage in cubic metres? Square feet is a floor and a foyer has a ceiling, so a double-height arrival eats capacity that a floor-area figure hides completely. Ours is 1000m³, about 2,000-3,000 sq ft. Two: waterless or water-based? It changes what enters your air and what lands on your surfaces. The Vaayu is waterless cold-air nebulisation of undiluted oil; the Sukoon is ultrasonic and water-based. Three: timer granularity? A restaurant does not want an on-off switch, it wants service hours. Ours is a Bluetooth app with 1h/4h/8h/24h windows. Four: is there a key-lock? In a restaurant a host, a manager and a cleaner will all reach a machine they can reach. Ours has one. Five: what is the measured dB? Ours is under 38dB. Six: mounting options? Freestanding, wall or HVAC - and this is the feature that keeps fragrance in a foyer and out of a dining room. Seven: power draw? Ours is 5W. Eight: what do you refuse to scent? A supplier with no refusals has not understood restaurants. Ours: dining rooms, chef's tables, tasting-menu rooms, the pass and kitchens stay unscented, no machine anywhere its output reaches a table, nothing edible anywhere, and nothing sold as a cover for cooking, grease, fish or a drain - fragrance is never a mask. Nine, and this is ours to answer badly: is the consumable an actual product, and will it exist next year? For our reeds, yes - 50ml 6-8 weeks, 130ml 14-18 weeks, refills at 300ml ₹2,399 and 500ml ₹3,499. For the Vaayu, no. It ships with 4 × 100ml, that 400ml is the entire supply today, it runs 90+ days a fill, and no cold-air refill is sold separately yet. Our Hotel Collection oils at ₹299, ₹999 and ₹1,799 are ultrasonic only and are never a Vaayu refill. For a ten-site rollout that is a real risk and you should get continuity of supply from us in writing. Ten: every commercial term on paper. Bulk and multi-site pricing, GST and corporate invoicing, AMC, warranty terms, installation, minimum order, lead time and rollout are not published by SOSA, and we make no delivery or timing promises - so ask, get it in writing, and treat a supplier who will not put it in writing as a risk to your programme. Then the sizing question you should ask yourself rather than us: size the non-dining envelope and not the restaurant. Under about 750 sq ft it is a Sukoon at ₹1,899 or an ₹849 Mountain Breeze reed and a Vaayu would be the wrong buy; a connected arrival volume is a Vaayu at ₹11,999. And plainly: SOSA does not publish a business-outcome number because it has not measured one. Ask for a restaurant scenting plan.
Ask for coverage in cubic metres, waterless or water-based, timer granularity, key-lock, measured dB, mounting options, power draw, what the supplier refuses to scent, consumable continuity, and every commercial term in writing. Our weakest answer is the consumable one: no separate cold-air refill for the Vaayu is sold today, and the 4 × 100ml supplied is the entire supply.
The machine behind these answers is the SOSA Vaayu - 1000m³, waterless, 1h/4h/8h/24h timers, key-lock, under 38dB, 5W, wall or HVAC mountable. ₹11,999. Under about 750 sq ft of arrival, the honest answer is a Sukoon at ₹1,899.

Cubic coverage, consumable continuity, and what they refuse to scent
The machine this list is answered about
Two products, with every checklist answer published rather than described. The images link to the product pages so a group's projects team can read each specification directly instead of taking my word for it.
Answers one to eight, published
SOSA Vaayu
1000m³ of coverage, about 2,000-3,000 sq ft. Waterless cold-air nebulisation of undiluted oil. Bluetooth app with 1h/4h/8h/24h timers, adjustable intensity, key-lock, under 38dB, 5W, auto-stop, freestanding or wall and HVAC mount, 400ml tank running 90+ days a fill. CE, RoHS and SGS - electrical and compliance marks, not a food claim.
From ₹11,999
Where the answers point to something smaller
SOSA Sukoon
Ultrasonic cool-mist diffuser covering roughly 270-320 sq ft, water-based, supplied with three 15ml hotel-inspired fragrances. Its consumable position is simpler than the Vaayu's because ultrasonic fragrance is sold as a product - which is exactly the kind of difference question nine is designed to surface.
From ₹1,899
The three questions suppliers dislike
Seven of the ten are specification questions and any decent supplier will answer them in a sentence. Three are uncomfortable, and the way a company handles those three tells you more than the other seven combined.
1
Ask for cubic coverage and watch the pause
A square-foot figure hides your ceiling, which is where capacity goes
Ambient scenting is a volume problem, so a coverage figure in square feet is either a translation or a marketing number. Ask for cubic metres and ask what assumption about ceiling height was used. Then do your own arithmetic: a 250 sq ft foyer at three metres is about 21m³; the same floor area under a six-metre shell is roughly double, and an atrium or a rooftop arrival eats capacity faster still. This matters most to a group, because your estate will contain at least one double-height arrival where a square-foot rating would have promised you something the room cannot deliver. Ours is 1000m³, about 2,000-3,000 sq ft, and I would rather you work from the first number.
Tip: Ask what ceiling height the supplier's square-foot figure assumes. If nobody knows, the figure was never a measurement.
2
Ask what they refuse to scent
A supplier with no refusals has not understood restaurants
This is the question I would ask first if I were buying. A company that will happily scent your dining room has not thought about the fact that the dish on the plate is the composition your guest paid for, or that a seated guest cannot walk away from a fragrance for three hours. Our refusals, in writing: dining rooms, chef's tables, tasting-menu rooms, the pass and kitchens stay unscented; no machine anywhere its output can reach a table; nothing edible in any zone; and nothing sold as a cover for cooking, grease, fish or a drain, because fragrance is never a mask and we sell no extractor, purifier or deodoriser. Ask also whether they will call a fragrance food-safe. We will not, because we have not tested for it.
Tip: Ask the supplier which of your sites they would decline. A company that declines none of them has not read your plans.
3
Then ask about the consumable, and about us
This is the question we answer worst, and it is named here on purpose
A group's exposure is not the machine, it is the refill. Ask: is the consumable a product with an SKU, a pack size and a price? Can you buy it in year two? Is it the same fragrance oil the machine was specified with? For our reeds the answers are clean - 50ml 6-8 weeks, 130ml 14-18 weeks, refills at 300ml ₹2,399 and 500ml ₹3,499. For the Vaayu they are not. The 4 × 100ml in the box is the entire supply today, it runs 90+ days a fill, and no cold-air refill is sold separately yet. The Hotel Collection at ₹299, ₹999 and ₹1,799 is ultrasonic only and is never a Vaayu refill. Get continuity in writing before you commit ten sites to it.
One Vaayu ₹11,999 ships with 4 × 100ml at 90+ days a fill - and the refill question should be answered on paper before a rollout, by us or anyone.

The SOSA principle
A buyer's checklist is only worth using if it can embarrass the company that published it, which is why ours keeps the question about consumable continuity in and answers it against us.

The SOSA plan
The buyer's checklist, answered for SOSA
| The question | What to do |
|---|---|
|
Coverage, waterless, power
|
Ask for cubic metres and the ceiling height assumed, whether it is waterless or water-based, and the power draw. SOSA Vaayu: 1000m³ (about 2,000-3,000 sq ft), waterless cold-air nebulisation of undiluted oil, 5W. Sukoon: ultrasonic and water-based, roughly 270-320 sq ft. |
|
Control and noise
|
Ask for timer granularity, adjustable intensity, key-lock and a measured dB figure - in a restaurant all four are load-bearing. SOSA Vaayu: Bluetooth app and buttons, 1h/4h/8h/24h timers, adjustable intensity, auto-stop, key-lock, under 38dB. |
|
Mounting options
|
Ask whether it can be wall or duct mounted, because that is what lets fragrance sit in a foyer and stay out of a dining room. SOSA Vaayu: freestanding, wall or HVAC mount, 165 × 80.5 × 215mm at 0.9kg. |
 Consumable availability and continuity
|
Ask whether the refill is a product with a price you can buy next year. Reeds: yes, 50ml 6-8 weeks, 130ml 14-18 weeks, refills 300ml ₹2,399 and 500ml ₹3,499. Vaayu: no. 4 × 100ml in the box is the entire supply today, 90+ days a fill, no cold-air refill sold separately yet, and Hotel Collection oils are ultrasonic only and never a Vaayu refill. |
|
What the supplier refuses
|
Ask for the refusals in writing. SOSA: dining rooms, chef's tables, tasting-menu rooms, the pass and kitchens unscented; no machine within reach of a table; nothing edible; nothing sold as a cover for cooking, grease, fish or a drain; and no fragrance described as food-safe. |
|
Commercial terms
|
Ask for all of it on paper. SOSA does not publish bulk or multi-site pricing, GST and corporate invoicing, AMC, warranty terms, installation, minimum order, lead time or rollout, and makes no delivery or timing promises. Get every one of those in writing before you commit. |
The cost side of this list - what is published, what is arithmetic and what genuinely cannot be quoted - is worked through in how much professional scenting costs for a premium restaurant in India. And the four honest non-coverage reasons a restaurant buys a commercial machine at all, which is the question underneath question one, are set out in when commercial waterless scenting makes sense for a restaurant. SOSA is independent and not affiliated with any hotel.
Ten questions, ours answered in public
SOSA Vaayu ₹11,999: 1000m³, waterless, 5W, under 38dB, key-locked, 400ml at 90+ days a fill - and no separate cold-air refill sold today.
If a supplier tells you they can scent your dining room, you have learned everything you need to know about them in one sentence, and you have not even reached the specification yet.

Three products, with every checklist answer published for each. Cold-air refill oil for the Vaayu is not currently sold separately, so the 4 × 100ml supplied runs 90+ days a fill and continuity must be confirmed with SOSA in writing before a group commits - which is precisely the question this page asks you to put to us.

SOSA Mountain Breeze reed diffuser
|
A single small arrival room, and the cleanest consumable answer we have | Pine, sage and cedar, alcohol-free and phthalate-free. 50ml lasts 6-8 weeks, 130ml 14-18 weeks, refills at 300ml ₹2,399 and 500ml ₹3,499 - a published, buyable consumable line | ₹849 View → |
|
SOSA Sukoon
|
An arrival envelope of roughly 300-750 sq ft | 270-320 sq ft coverage, water-based, three 15ml fragrances included. A Vaayu would be the wrong buy at this size, and the ultrasonic fragrance line is sold as a product | ₹1,899 View → |
|
SOSA Vaayu
|
A connected arrival volume where control and mounting matter | 1000m³, waterless, 1h/4h/8h/24h timers, adjustable intensity, key-lock, under 38dB, 5W, wall or HVAC mount. 4 × 100ml supplied at 90+ days a fill, and no separate cold-air refill sold today | ₹11,999 View → |
Use this list on us and on everyone else, and write the answers down rather than collecting brochures. Ambient scent in a restaurant is an ambience decision like lighting; it is never a mask for cooking, grease, fish, smoke or a drain, and we sell no extractor, purifier or deodoriser; and the dining room, the chef's table, any tasting-menu room and the pass stay unscented in every restaurant, with no machine placed where its output can reach a table. I will not describe any fragrance as food-safe or safe for use around food, because we have not tested for that and will not imply it, and anything sited near a food-preparation area is a question for your kitchen consultant and your local authority rather than for me. Fragrance oil is flammable, so oil and machine stay away from open flame and heat - table candles, flambé service, tandoors and ranges. Bulk and multi-site pricing, GST and corporate invoicing, AMC, warranty terms, installation, minimum order, lead time and rollout are not published, and a group should have every one of them in writing before committing. And plainly: SOSA does not publish a business-outcome number because it has not measured one - no covers, no table turns, no spend per head, no bookings. Ask for a restaurant scenting plan before you spend anything.

A note from Sonal
What groups ask me at this stage is usually a version of "what should we be careful of", and the honest reframe is that they should be careful of me too. So I wrote the list I would use if I were on the buying side, and then I kept in the question I answer worst. Seven of the ten are specification questions and any competent supplier answers them in a sentence. The interesting three are the cubic coverage figure, the list of things the supplier refuses to scent, and whether the consumable is a real product you can buy again next year.
The first two are easy for us. Coverage is 1000m³ and I would rather you work in cubic metres than square feet, because a double-height arrival eats capacity that a floor-area figure conceals. And our refusals are long and public: dining rooms, chef's tables, tasting-menu rooms, the pass and kitchens, no machine within reach of a table, nothing edible, nothing sold as a cover for an odour, and no fragrance described as food-safe. If a supplier offers to scent your dining room, you have your answer about them before you reach the specification.
The third one is ours to lose. The Vaayu at ₹11,999 ships with 4 × 100ml, that 400ml is the entire supply today, it runs 90+ days a fill, and no cold-air refill is sold separately yet. The Hotel Collection oils at ₹299, ₹999 and ₹1,799 are ultrasonic only and are never a Vaayu refill. For a group planning ten sites that is a real risk, so put it in your paperwork and get continuity of supply from us in writing - along with bulk pricing, GST and corporate invoicing, AMC, warranty, installation, minimum order and lead time, none of which we publish. Where the arrival is smaller, the Mountain Breeze reed at ₹849 and the Sukoon at ₹1,899 have simpler answers. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What should a restaurant group ask a commercial scenting company before installing machines?
Ten things: coverage in cubic metres rather than square feet, waterless or water-based, timer granularity, whether there is a key-lock, a measured dB figure, mounting options, power draw, what the supplier refuses to scent, whether the consumable is a buyable product with continuity, and every commercial term in writing. Write the answers down. The three a supplier handles awkwardly tell you more than the seven they answer fluently.
Why ask for coverage in cubic metres instead of square feet?
Because a foyer has a ceiling and ambient scenting is a volume problem. A 250 sq ft arrival at three metres is about 21 cubic metres; the same floor area under a six-metre shell is roughly double, and an atrium eats capacity faster still. A square-foot figure hides that entirely. The SOSA Vaayu is rated at 1000 cubic metres, about 2,000 to 3,000 sq ft, and the first number is the one to plan from.
What is SOSA's weakest answer on this checklist?
Consumable continuity for the Vaayu. The machine ships with 4 x 100ml, that 400ml is the entire supply today, it runs 90+ days a fill, and no cold-air refill is sold separately yet. Our Hotel Collection oils at Rs 299, Rs 999 and Rs 1,799 are ultrasonic only and are never a Vaayu refill. For a ten-site rollout that is a genuine risk, so get continuity of supply from us in writing before committing.
What commercial terms should we get in writing?
All of them, because SOSA publishes none of them: bulk and multi-site pricing, GST and corporate invoicing, AMC, warranty terms, installation, minimum order, lead time and rollout. We also make no delivery or timing promises. Ask for each on paper with a date against it, and treat any supplier who will not put the same terms in writing as a risk to your programme rather than as a bargain.
Should we ask a supplier to prove a return on the investment?
You can ask, but SOSA does not publish a business-outcome number because it has not measured one. No covers, no table turns, no spend per head, no bookings, and a supplier quoting a figure is selling rather than reporting. A better question is what the company refuses to scent, because a supplier with no refusals has not understood that a dining room is where the food is the fragrance.
Ten questions, and our own worst answer left in
SOSA — Clinic Scenting for restaurant groups buying commercial scenting
The SOSA Vaayu (₹11,999) answers the list in public: 1000m³ of coverage, waterless cold-air nebulisation, 1h/4h/8h/24h timers, adjustable intensity, key-lock, under 38dB, 5W, freestanding or wall and HVAC mount, 400ml running 90+ days a fill. No separate cold-air refill is sold today and the Hotel Collection oils are ultrasonic only, never a Vaayu refill, so get continuity in writing. Under about 750 sq ft of arrival the honest answer is a Sukoon at ₹1,899 or a Mountain Breeze reed at ₹849. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

Editorial standards & sources
About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the planning advice applies to any brand.Facts verified 5 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 adjustable intensity, a 400ml refillable tank lasting 90+ days a fill depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB at 5W, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification, which are electrical and compliance marks and not medical approvals. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering roughly 270-320 sq ft and is supplied with three 15ml fragrances; the water-based Hotel Collection (₹299 / ₹999 / ₹1,799) is an ultrasonic fragrance and is not a refill for a waterless cold-air machine. SOSA reed diffusers are alcohol-free and phthalate-free, with 50ml lasting about 6-8 weeks and 130ml about 14-18 weeks. Cold-air refill oil for the Vaayu is not currently sold separately - the machine ships with 400ml included and further refills should be confirmed with SOSA. Warranty, annual maintenance, installation and bulk terms are not published and should be confirmed before ordering. Ambient scent is an interior and hospitality decision: it makes no clinical, therapeutic or wellbeing claim, it works alongside proper extraction, grease management, drainage, cleaning and air change and is never a substitute for any of them, it is never used to mask or remove another smell, and no claim is made that fragrance influences a guest's decision or any commercial outcome. Dining rooms, chef's tables, tasting-menu rooms and food-preparation areas are left unscented, no machine is placed where its output can reach a table or a pass, no fragrance is described as food-safe or safe for use around food, and the operator's own kitchen consultant and local food-safety and fire authority govern anything sited near a kitchen. Fragrance oil is flammable and is kept away from open flame and heat. The chef's judgement overrides any scenting plan in their own room. 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.
