"Our villa in Lonavala sits shut for eleven days out of fourteen, and it used to greet us with that closed-up monsoon smell. Now the machine runs an hour before we arrive and the house smells like a suite we checked into. My husband opens the door and just stands there."

"We have a 4BHK and people over almost every Saturday. Cooking, marigolds, someone's perfume, the dog - by nine at night the ground floor used to smell like all of it at once. One scent through the entrance, living and dining fixed it. Nobody asks about it, everybody notices it."

"I have been chasing that hotel-lobby smell since a stay in Bangkok in 2019. Candles, sprays, three different reed brands, none of it held past an hour. This is the first thing that made my own hallway smell that way at seven in the morning without me doing anything."

Which Vaayu bundle is best for Diwali hosting? Bundle A if you want the safest Diwali coverage, because it contains Ritz-Carlton-inspired, Westin-inspired, St. Regis-inspired and 1 Hotels-inspired - which is both clean picks, the dry green one and the warm evening one in a single box. Bundle B is Westin-inspired, Shangri-La-inspired, Four Seasons-inspired and Ritz-Carlton-inspired, so it holds both clean white-tea registers plus two brighter floral and citrus directions, and it suits a home that leans light and garden-facing. Bundle C is St. Regis-inspired, W Hotels-inspired, 1 Hotels-inspired and Four Seasons-inspired, which is the most characterful set and the one to choose if your house is dark-wood and formal and your Diwali evenings are adult and late. All three include at least one register that is genuinely right for Diwali, so the decision is about the rest of the year as much as the festival.
Which fragrance should you avoid at Diwali? Any register you would describe as sweet, and any register run at a level you would use in an empty room. Sweetness is the trap, because the room is already sweet - mithai in open boxes, ghee in everything, khoya, dry fruit, two days of frying - and fragrance adds to what is there rather than replacing it, so sweet on sweet in a warm crowded room produces something cloying within about an hour. None of the seven SOSA registers is a gourmand, which genuinely helps, but the warmer end of the range still needs care: the St. Regis-inspired amber, violet and woods and the W Hotels-inspired citrus, pepper and amber both carry more character and read as more present in a room, so they want a bigger or better ventilated space and a lighter hand than you would give them in winter. The clean, dry, bright end is the safer direction on this one night.
See the Vaayu
Facts verified August 2026: The SOSA Vaayu (₹11,999) is a waterless cold-air nebulising machine covering approximately 1000m³, with Bluetooth app and timer scheduling. It ships with four hotel-inspired waterless blends included in the box, chosen as one of three bundles at purchase: Bundle A - Ritz-Carlton Inspired, Westin Inspired, St. Regis Inspired, 1 Hotels Inspired; Bundle B - Westin Inspired, Shangri-La Inspired, Four Seasons Inspired, Ritz-Carlton Inspired; Bundle C - St. Regis Inspired, W Hotels Inspired, 1 Hotels Inspired, Four Seasons Inspired. Format distinction: the Vaayu and the HVAC systems run waterless nebulising oil, while the separate SOSA Hotel Collection fragrance (15ml ₹299) is water-based and runs in the ultrasonic machines only - Boond (₹899), Sukoon (₹1,899) and Megh (₹3,499). The two fragrance formats are not interchangeable, and the Hotel Collection bottle does not go into a Vaayu. SOSA Aangan (₹25,999) and SOSA Meenar (₹38,500) are HVAC nebulising systems for approximately 8,000-10,000 sq ft and 12,000-18,000 sq ft respectively, ducted into central air-conditioning. Reed diffusers need no power and make no noise: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml from ₹1,249; duo sets ₹1,498, ₹1,548 and ₹1,598. Scent perception is personal and varies between people in the same room, and coverage figures assume connected air volume rather than a partitioned floor plan. Ventilation, cleaning and air-conditioning come first; fragrance is an addition to a well-kept home and never a substitute for any of them. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any hotel brand. Made in India, cruelty-free and vegan. A portion of every order supports girl-child education through Nanhi Kali. Ongoing fragrance supply is arranged with SOSA on WhatsApp: +91 96192 18531. Prices and availability are subject to change - see the live product pages.
There are seven hotel-inspired registers in the SOSA range and no Diwali blend among them, which is worth saying at the start rather than pretending otherwise. So the useful question is not which one is the festival fragrance, it is which one behaves well in Diwali air: a warm, crowded room already holding mithai, ghee, two days of frying, marigold, flame and thirty people's own perfumes. This page routes all seven honestly against that room, tells you which bundle to choose, and says plainly where each one is the wrong idea.
Quick answers — read this first
Which SOSA fragrance should I choose for a Diwali party? The Ritz-Carlton-inspired blend of white tea, bergamot and cedar if you want one answer, because it is clean and calm with a bright lift that reads well against rich food. The Westin-inspired white tea, aloe and cedar is the equally safe alternative and is the quietest of the seven, which makes it the easiest thing to run in front of a mixed family crowd. If your home is more grounded than polished - wood, stone, plants - the 1 Hotels-inspired cedarwood, vetiver and green leaves is the driest and greenest of the seven and reads very differently from cooking rather than blurring into it. The St. Regis-inspired amber, violet and woods is the warm evening option for a formal drawing room, but it wants a bigger or better ventilated space and a lighter hand. Four of the seven arrive in the box with the SOSA Vaayu at Rs 11,999 as Bundle A, B or C. SOSA is not affiliated with any hotel brand.Which Vaayu bundle is best for Diwali hosting?

The short answer
Short answer: There is no Diwali blend in the SOSA range and we would rather say so than invent one. The useful question is which of the seven hotel-inspired registers behaves well in Diwali air - a warm crowded room already holding mithai, ghee, two days of frying, marigold, flame and thirty perfumes. Clean and bright wins, because sweet compounds rather than balances. Ritz-Carlton-inspired, white tea, bergamot and cedar: the one-answer pick, clean and calm with a bright lift against rich food. Westin-inspired, white tea, aloe and cedar: the quietest of the seven and the safest in front of a mixed family crowd. 1 Hotels-inspired, cedarwood, vetiver and green leaves: the driest and greenest, right for a home of wood, stone and plants, and it reads very differently from cooking rather than blurring into it. St. Regis-inspired, amber, violet and woods: the warm evening option for a formal drawing room, but it needs a bigger or better ventilated room and a lighter hand. Shangri-La-inspired, jasmine, green tea and white tea: for a garden-facing house, though think twice if you have a lot of tuberose in the garlands. Four Seasons-inspired, citrus, floral and sandalwood: bright and sociable for daytime visits. W Hotels-inspired, citrus, pepper and amber: the boldest, and the one that wants the lightest hand. These are character descriptions only - there is no published ranking by throw or longevity, which is set by the machine, the setting and the room. Bundle A is Ritz-Carlton, Westin, St. Regis and 1 Hotels; Bundle B is Westin, Shangri-La, Four Seasons and Ritz-Carlton; Bundle C is St. Regis, W Hotels, 1 Hotels and Four Seasons. Four blends come in the box with the Vaayu at Rs 11,999. The water-based Hotel Collection from Rs 299 is for ultrasonics only - Boond Rs 899, Sukoon Rs 1,899, Megh Rs 3,499 - and never goes into a Vaayu. SOSA is not affiliated with any hotel brand. WhatsApp +91 96192 18531.
The pick: the SOSA Vaayu (₹11,999, four hotel-inspired blends included in the box) for the connected living volume of a villa; reeds from ₹749 for a single bedroom or bathroom; a single room done properly from ₹899; the Aangan (₹25,999) ducted into central air-conditioning for genuine whole-home coverage.

In this guide
A villa is not one room, it is a set of connected volumes and a set of closed doors, and the two need different answers. Whole-home scenting means one fragrance held evenly across the part of the house you actually live in - the entrance, the living room, the dining - running on a schedule so it is already there when someone walks through your front door, and already there when you come home yourself. The bedrooms, the guest bathroom and the study get their own quiet solutions. Nobody in the house has to remember anything.

Straight answer
Which of the seven SOSA registers should actually run on Diwali night, and which bundle should you choose?
The rule first: choose contrast, not harmony. Your room already holds mithai, ghee, khoya, two days of frying, marigold and flame, and fragrance joins that rather than replacing it - so sweet compounds into cloying while clean contrasts and reads as fresh air. The router. Ritz-Carlton-inspired (white tea, bergamot, cedar) - the one-answer pick: hushed lobby calm with a bright bergamot lift that reads well against rich food. Westin-inspired (white tea, aloe, cedar) - the quietest of the seven and the safest thing to run in front of a mixed family crowd. 1 Hotels-inspired (cedarwood, vetiver, green leaves) - the driest and greenest; right for a home of wood, stone and plants, and about as far from ghee as the range goes. St. Regis-inspired (amber, violet, woods) - plush and evening-elegant, the honest warm choice for a formal dark-wood drawing room, but it reads as more present in a room and so wants a bigger or better ventilated space and a lighter hand. Shangri-La-inspired (jasmine, green tea, white tea) - for a garden-facing house; think twice if your garlands are heavy with tuberose. Four Seasons-inspired (citrus, floral, sandalwood) - bright and sociable, good for daytime visits across the week. W Hotels-inspired (citrus, pepper, amber) - the boldest of the seven, and the one that wants the lightest hand of all. These are character notes only; there is no published ranking by throw or longevity, which in practice is set by the machine, the setting and the room. The bundles. Four blends come in the box with the Vaayu at ₹11,999. Bundle A: Ritz-Carlton, Westin, St. Regis, 1 Hotels - the safest Diwali coverage. Bundle B: Westin, Shangri-La, Four Seasons, Ritz-Carlton - lighter and garden-facing. Bundle C: St. Regis, W Hotels, 1 Hotels, Four Seasons - the most characterful, for a formal late-evening house. If you own an ultrasonic - Boond ₹899, Sukoon ₹1,899, Megh ₹3,499 - the same seven registers exist as the water-based Hotel Collection from ₹299, with a 100ml refill at ₹999 and a Pack of 7 at 15ml for ₹1,799. That bottle never goes into a Vaayu; the formats are not interchangeable. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is not affiliated with any hotel brand. WhatsApp +91 96192 18531. Made in India; a portion of every order supports girl-child education through Nanhi Kali.
One line: Ritz-Carlton-inspired or Westin-inspired white tea for the safe Diwali pick, 1 Hotels-inspired for a grounded house, St. Regis-inspired only in a bigger aired room with a lighter hand - and nothing sweet, because the mithai is already doing that. Four blends in the box with the Vaayu at ₹11,999. WhatsApp +91 96192 18531.
The whole-home answer most villa owners land on: the SOSA Vaayu - waterless cold-air scenting to ~1000m³, Bluetooth app and timer, and four hotel-inspired blends included in the box - at ₹11,999. One bedroom or a guest bathroom starts on reeds from ₹749; a single room done properly from ₹899; central air-conditioning from ₹25,999.

The seven registers, read for Diwali air
The seven registers read against a warm crowded festival room, the bundle decision, and the format rule that decides what you can actually buy.
1
The router
All seven, honestly, against a Diwali room
Character only, because there is no published data ranking these registers by throw, longevity or intensity, and throw in practice is set by the machine, the setting and the volume of the room rather than by the blend. Ritz-Carlton-inspired - white tea, bergamot, cedar. Soft white tea and bright bergamot over clean cedar: the hushed, polished calm of a grand hotel lobby. The bergamot lift is why it is the strongest single Diwali answer, because bright reads as a contrast against rich food rather than merging into it. Westin-inspired - white tea, aloe, cedar. The famous spa-like white tea signature, serene and cooled by aloe. The quietest of the seven, which makes it the easiest thing to run in front of a mixed crowd of relatives who did not choose it. 1 Hotels-inspired - cedarwood, vetiver, green leaves. Barefoot, biophilic luxury: fresh green leaves, earthy vetiver, warm cedarwood. The driest and greenest in the range, and the furthest from ghee and mithai, which is exactly why it works in a house that has been frying for two days. Right for homes with stone, wood and plants rather than gilt and velvet. St. Regis-inspired - amber, violet, woods. Powdery violet, warm amber, polished woods: refined, plush and evening-elegant, the richest register here and the one people picture when they imagine a festival fragrance. It is genuinely lovely in a formal dark-wood drawing room after dark - but a warmer register reads as more present in a room than an airy white-tea one, and a warm crowded Diwali room amplifies exactly that, so give it a genuinely large or well-ventilated space and a lighter hand than you would in January. Shangri-La-inspired - jasmine, green tea, white tea. Tea and night-blooming jasmine; beautiful in a house that opens onto a garden. Worth a second thought if your garlands are heavy with tuberose, since that is already a large floral presence. Four Seasons-inspired - citrus, floral, sandalwood. Bright, polished hospitality, kept from thinness by creamy sandalwood; good for daytime visits across the festival week. W Hotels-inspired - citrus, pepper, amber. Bold and playful, zesty citrus with a kick of pepper and sultry amber: the most characterful of the seven and the one that wants the lightest hand of all on this night.
Tip: none of the seven is a gourmand, which is genuinely useful at Diwali - but the warm end still needs a bigger room and a lighter hand.

The bundle
Which four you actually get, and how to choose
The Vaayu at ₹11,999 ships with four hotel-inspired waterless blends in the box, chosen as one of three bundles at checkout, which is unusual enough to be worth surfacing: most people assume the fragrance is sold separately. Here is how the three read for a house that hosts at Diwali. Bundle A - Ritz-Carlton, Westin, St. Regis, 1 Hotels. The best Diwali coverage of the three, because it contains both clean white-tea picks, the dry green register and the warm evening one, so you have the right answer for a crowded early evening, for a formal late one, and for a grounded house, all in the same box. If you are buying with the festival in mind, this is the one. Bundle B - Westin, Shangri-La, Four Seasons, Ritz-Carlton. The lighter set: both white teas plus a jasmine-and-tea floral and a citrus-floral-sandalwood. It suits a bright, garden-facing home, and it is the friendliest bundle for daytime visits during the festival week. Its warm option is absent, which matters only if you host formal late evenings. Bundle C - St. Regis, W Hotels, 1 Hotels, Four Seasons. The most characterful: the plush amber-violet-woods, the bold citrus-pepper-amber, the dry green and the bright citrus-floral. This is the right choice for a dark-wood, formal house with adult, late Diwali evenings, provided you accept that two of its four want a lighter hand in a crowd. Two practical notes. Choose the bundle for the whole year rather than for one week, since the machine will run every ordinary evening as well. And having four blends is genuinely useful for auditioning across ordinary weeks and then settling on one for the festival, rather than for rotating during it - a house that changes register mid-week reads as a house that keeps spraying things.

The format
What you can actually buy, and the one mistake to avoid
This is the part where people go wrong, so it is worth stating without ambiguity. There are two fragrance formats and they are not interchangeable. The Vaayu at ₹11,999 is a waterless cold-air nebulising machine and it runs waterless oil - the four hotel-inspired blends that come in its box as Bundle A, B or C. The water-based SOSA Hotel Collection, which is the same seven registers in a different format, is for the ultrasonic machines only: Boond ₹899, Sukoon ₹1,899 and Megh ₹3,499. That water-based bottle is ₹299 for 15ml, ₹999 for a 100ml refill, and ₹1,799 for a Pack of 7 at 15ml - which, if you own an ultrasonic and cannot decide, is the honest answer to which register to buy for Diwali, because it removes the guess entirely at a published price. The ₹299 bottle never goes into a Vaayu. Two more honest limits while we are here. We publish no refill price, consumption figure, running cost or blend duration for the Vaayu, because no standalone waterless refill is listed - what drives consumption is the volume you are scenting, the hours the schedule runs and the intensity setting, and ongoing supply is arranged with us directly on WhatsApp at +91 96192 18531. And whichever register you land on, the level does more work than the choice: run it below your ordinary setting on Diwali night, because a warm crowded room carries scent further than the empty one you calibrated in. If you would rather not own a machine at all, reeds from ₹749 in the same character family cover a guest bathroom or a hall with no power and nothing to switch on.
Tip: waterless blends come with the machine; the ₹299 water-based bottle is for the ultrasonics - and the two are never swapped.
The SOSA principle
There is no Diwali blend, and there does not need to be. Choose contrast: clean, bright or dry green against a room that is already sweet and warm.

The SOSA home edit
Whatever the house looks like, the logic is the same: one scent, sized to the volume that is genuinely connected, running on a schedule so nobody in the family has to remember it. A single bedroom or a guest bathroom is happy on reeds with no power at all; the living room you actually live in wants a machine; the whole villa with central air-conditioning wants the ducts doing the work. Every SOSA system is made in India, cruelty-free and vegan, and a portion of every order supports girl-child education through Nanhi Kali. Here is where each one belongs.

Honest notes before you buy anything. Coverage ratings assume connected air volume. A machine cannot push scent through a closed bedroom door, and it never will - so a partitioned villa is not one scenting problem but several, and honest sizing means saying so out loud rather than selling you one machine and hoping. Scent the volume that is genuinely open to itself, then give the closed rooms their own quiet answer, usually a reed diffuser. Fragrance never substitutes for ventilation or cleaning. If a room smells damp, stale or of last night's cooking, open it, air it and clean it first; scent added on top of that only makes a more complicated bad smell. A home is not a lobby you pass through. Households include children, elderly parents, pregnant family members and pets, all of whom breathe this air far longer than any visitor does, which is why gentle dosing is the default at home and why the settings we suggest are lower than the machine can run. Anyone in the house reporting a headache is a recalibration signal, not a complaint to argue with - turn it down or turn it off, and tell us. The Vaayu runs waterless nebulising oil and comes with the four hotel-inspired blends; the Hotel Collection bottle is water-based and belongs in the ultrasonic machines only. The two formats are not interchangeable. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house, not affiliated with or endorsed by any hotel brand. Ongoing fragrance supply for the Vaayu is arranged with us directly on WhatsApp: +91 96192 18531. A portion of every order supports girl-child education through Nanhi Kali.

A note from Sonal
There is a difference between a room that smells nice and a home that has a signature, and almost nobody is told what it is. A room that smells nice is an event: you light a candle, you spray something in the hallway before people arrive, it is lovely for forty minutes and then it is gone. Somewhere else in the house a bathroom gel is doing one thing, a kitchen spray another, and a bedroom reed a third. Four pleasant smells in four rooms is not a fragranced home. It is four rooms.
A signature is the opposite. It is one scent, sized to the house, running on a schedule - so it is already in the air when someone walks through your front door, and already there at eleven at night when you come home yourself, and nobody has lifted a finger to make it happen. That is the whole trick the great hotels use, and it is not complicated: they do not chase smells room by room, they hold one fragrance across the volume people actually move through. In a villa that usually means the entrance, the living room and the dining as one connected space, with the closed rooms handled separately and quietly.
I trained at ISIPCA in Versailles and I have sized this for houses across India, and I would rather tell you honestly that your layout needs two answers than sell you one machine that disappoints you. Message us on WhatsApp at +91 96192 18531 with your home's approximate size, the number of floors and a line about the layout - open plan, closed rooms, central air-conditioning or split units - and we will give you a free sizing recommendation. I read those descriptions myself. Everything is made in India, cruelty-free and vegan, and a part of every order funds girl-child education through Nanhi Kali. Your home gets a memory; a girl gets a classroom.
Frequently asked questions
If I can only choose one register for Diwali, which is it?
The Ritz-Carlton-inspired blend of white tea, bergamot and cedar. It is clean and calm like the Westin-inspired one, but the bergamot gives it a bright lift, and bright is what you want in a room holding mithai, ghee, two days of frying and thirty warm bodies - it reads as a contrast beside the food rather than merging into it. If your household includes anyone who finds citrus sharp, or if you want the quietest possible thing in front of a large mixed family gathering, the Westin-inspired white tea, aloe and cedar is the alternative and is the most serene of the seven. If your home is more natural than polished - wood, stone, plants, a lot of light - the 1 Hotels-inspired cedarwood, vetiver and green leaves is the better fit and is the driest register in the range. All three are in the Vaayu bundles: A carries the Ritz-Carlton-inspired, Westin-inspired and 1 Hotels-inspired together, which is why it is the bundle we would suggest for a house that hosts at Diwali. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is not affiliated with any hotel brand.
Can I use the St. Regis-inspired amber for Diwali? It sounds festive.
Yes, in the right room and at a lighter hand than you would use in winter. It is the richest register in the range - powdery violet, warm amber and polished woods - and it is genuinely beautiful for a formal, adult, late Diwali evening in a dark-wood drawing room. The honest caution is perceptual rather than technical: a warmer amber-and-woods register reads as more present in a room than an airy white-tea one, and a Diwali room is warm, crowded and already carrying rich food, all of which amplify that presence further. So it wants a genuinely large or well-ventilated space, a setting below the one you would use on an ordinary evening, and a plan to leave it alone once people arrive. Where it goes wrong is a smaller closed sitting room with thirty people in it and mithai on the table, which is where the compounding problem shows up fastest. If your Diwali is a big family gathering with children and elderly relatives in a moderate space, take the clean route instead and save this for a quieter evening.
I have a Sukoon and the Rs 299 Hotel Collection. Is that enough for Diwali?
For one room, yes, and it is a perfectly honest answer rather than a compromise. The Sukoon at Rs 1,899 is a water-based ultrasonic and it runs the Hotel Collection from Rs 299, and one gently run ultrasonic in a single room does that room properly. What it will not do is hold a whole connected ground floor - coverage assumes one connected volume, and a small ultrasonic is sized for a room rather than a floor - so on Diwali night, when internal doors are open and guests use everything, expect it to be a room-level effect rather than a house-level one. Two ways to extend it without a machine: put reeds from Rs 749 in the guest bathroom and hall in the same character family so the route does not change subject, and if you want one large room done properly, a Megh at Rs 3,499 on the same water-based format is the honest cheaper step. The Pack of 7 at 15ml for Rs 1,799 is worth knowing about if you want to try registers before the festival. That water-based bottle never goes into a Vaayu.
Should I buy a different register just for the festival season?
Usually not, and the reason is that consistency is what makes a house read as having a character. Relatives and neighbours come in and out repeatedly across the festival week, and a house that smells the same at each visit is memorable in the way a hotel is, while a house that smells different every few days reads as a house that keeps buying things. There is also a nose problem: yours adapts within minutes, so the impulse to buy something new is very often the sensation of no longer detecting what you already have rather than a real judgement about it. Where a second register genuinely earns its place is seasonal rather than festival-specific - a lighter one for summer, a warmer one for winter evenings - and that is exactly what having four blends in the Vaayu box at Rs 11,999 is useful for. If you want to explore registers cheaply and you own an ultrasonic, the water-based Hotel Collection Pack of 7 at 15ml for Rs 1,799 is the sensible way to do it.
Which register works best with marigold, incense and everything else already in the house?
The dry and clean ones, because they occupy a different part of the spectrum from everything else in the room rather than competing in the same one. Marigold is green and slightly bitter, tuberose is heavy and floral, incense at the puja space is smoky and resinous, and the food is warm and sweet - which means the gaps left are clean, airy and dry green. That is precisely where the 1 Hotels-inspired cedarwood, vetiver and green leaves sits, and it is why it works better in a full Indian house than its quiet reputation suggests: dry green is related enough to marigold to feel coherent and far enough from ghee to register as fresh. The white-tea registers do the same job from the airy side rather than the green one. The register we would think twice about in a house full of tuberose is the Shangri-La-inspired jasmine, green tea and white tea, simply because it adds a large floral to a room that already has one. And nothing you run should go anywhere near the incense or the lamp in the puja room, which stays unscented.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA home range; the sizing logic applies to any brand's systems.Facts verified August 2026: The SOSA Vaayu (₹11,999) is a waterless cold-air nebulising machine covering approximately 1000m³, with Bluetooth app and timer scheduling. It ships with four hotel-inspired waterless blends included in the box, chosen as one of three bundles at purchase: Bundle A - Ritz-Carlton Inspired, Westin Inspired, St. Regis Inspired, 1 Hotels Inspired; Bundle B - Westin Inspired, Shangri-La Inspired, Four Seasons Inspired, Ritz-Carlton Inspired; Bundle C - St. Regis Inspired, W Hotels Inspired, 1 Hotels Inspired, Four Seasons Inspired. Format distinction: the Vaayu and the HVAC systems run waterless nebulising oil, while the separate SOSA Hotel Collection fragrance (15ml ₹299) is water-based and runs in the ultrasonic machines only - Boond (₹899), Sukoon (₹1,899) and Megh (₹3,499). The two fragrance formats are not interchangeable, and the Hotel Collection bottle does not go into a Vaayu. SOSA Aangan (₹25,999) and SOSA Meenar (₹38,500) are HVAC nebulising systems for approximately 8,000-10,000 sq ft and 12,000-18,000 sq ft respectively, ducted into central air-conditioning. Reed diffusers need no power and make no noise: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml from ₹1,249; duo sets ₹1,498, ₹1,548 and ₹1,598. Scent perception is personal and varies between people in the same room, and coverage figures assume connected air volume rather than a partitioned floor plan. Ventilation, cleaning and air-conditioning come first; fragrance is an addition to a well-kept home and never a substitute for any of them. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any hotel brand.
