So how do I find the right number for my city? On foot, in your own doorway, and never from a chart. Stand outside in the street air for a few minutes, walk back in through the door your customer uses, and judge the first breath and nothing else - your nose adapts within about twenty minutes of arriving, so the only honest measurement is the one taken from outside. Then sit at the consultation table for a full ninety minutes, because that seat sets the ceiling. Anyone who hands you a humidity percentage or a seasonal adjustment figure has invented it, and I would rather say that than pretend to a number SOSA has not measured.
Does the machine change between cities, then? No, only the size of the room does. Under about 750 sq ft the honest buy anywhere in India is one SOSA Sukoon at ₹1,899 or a Mountain Breeze reed at ₹849, and a Vaayu would be the wrong buy. From roughly 1,500 sq ft, one SOSA Vaayu at ₹11,999, and past roughly 5,000 sq ft with central air handling an Aangan at ₹25,999. Cubic volume decides which row you are on, and the climate decides nothing about it at all - so measure length by width by height in metres before you look at a single product page.

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 ventilation, cleaning and infection control and is never a substitute for any of them, it is never used to mask another smell, and no claim is made that fragrance influences a patient's decision or any commercial outcome. Clinical areas including procedure, post-procedure and photography rooms are left unscented, and the treating clinician'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 question underneath all nine of the city pages, and the answer is shorter than anyone expects: the strategy does not change with the climate, and the setting does. What is worth explaining properly is why - because once you see what the air conditioning has actually done to the inside of your showroom, the whole seasonal-adjustment industry starts to look rather thin.
Quick answers — read this first
Does a kitchen showroom need a different scenting strategy in humid vs dry Indian cities? No. The strategy is identical and only the number changes. One dry, material-led profile - dry woods, green and herbal, tea, clean mineral, nothing edible - chosen from your displays and your price point rather than your postcode, held at one low level on a trading-hours timer. What humid and dry cities do is change how that same level arrives: damp air holds a fragrance and lets it hang; dry air carries it further and delivers it with the outline intact. Both of those point the dial downward from a naive starting point, for different reasons.So how do I find the right number for my city? On foot, in your own doorway, and never from a chart. Stand outside in the street air for a few minutes, walk back in through the door your customer uses, and judge the first breath and nothing else - your nose adapts within about twenty minutes of arriving, so the only honest measurement is the one taken from outside. Then sit at the consultation table for a full ninety minutes, because that seat sets the ceiling.

The short answer
Short answer: no - the strategy is the same everywhere and only the number changes. One dry, material-led profile with nothing edible, chosen from your displays rather than your postcode, run at a different honest level in each showroom. Humid air holds a fragrance and dry air delivers it sharply, so both point the dial downward from a naive start. The direction is knowable, the figure is not, and it is found by walking in from the street.
The pick: one SOSA Vaayu (₹11,999) per genuinely separate volume from about 1,500 sq ft, with the intensity set locally and key-locked, or one SOSA Sukoon (₹1,899) wherever the showroom is a single room under about 750 sq ft.
Next step: send us the floor plan for each branch with ceiling heights and the hours the air conditioning runs, and we will suggest one profile, one machine class and a starting number per showroom that your own team then verifies on foot - Ask for a retail scenting plan.
In this guide
Once the doors are shut and the air conditioning is running, showroom interiors across India converge. What still differs city to city is the step your customer takes from the street into the room - and that step, rather than the climate, is what the setting is really answering.

Straight answer
Does a kitchen showroom really need a different scenting strategy in a humid city than in a dry one?
No. It needs the same strategy at a different number, and the difference between those two sentences is most of what this family of pages exists to say. Start with what does not move. The profile is a brand decision made once, from your displays and your price point, and it is the same in Mumbai as it is in Jaipur: dry woods such as cedar, pine and sage for timber and warm displays, the brighter green end run low for white and grey minimal rooms, and nothing edible at any point. No vanilla, no baking, no coffee, no caramel, no warm spice, in any city, in any season. SOSA's own Fresh Brew at ₹849 is Coorg coffee and Kerala vanilla and it is exactly the register a kitchen showroom must keep out - a room selling ₹5-10 lakh cabinetry that smells of food reads as a café, and it argues with any live cooking you have deliberately staged. Now what does move. Two mechanisms, and they are worth understanding because they explain the whole family. Humid air is a heavier, slower medium: the same output hangs about rather than dispersing, so a level that was honest in a dry month arrives as too much in a wet one. That is Mumbai and Chennai, and the wet-season adjustment is downward however strongly the damp weather suggests otherwise. Dry air is a clearer medium: it carries a fragrance further and delivers it with its outline intact, so the same number arrives more distinctly. That is Ahmedabad and Jaipur, and owners there routinely misread clarity as dilution and turn the dial up when it should go down. Notice that both roads lead to the same instruction - and that neither of them touched the fragrance. Then the fact that undercuts the whole seasonal-adjustment story: an air-conditioned showroom in Mumbai and an air-conditioned showroom in Jaipur are far more like each other than either is like its own street. The plant dries the air, moves it, and holds the room somewhere near the same place all day. So what your dial is genuinely set against is not the climate of your city; it is the size of the step your customer takes on the way in from that climate, and how long the room has to reassert itself between one glass door opening and the next. That is why every page in this family sends you to the pavement. Stand outside for a few minutes, walk in through the customer's door, judge the first breath and nothing else, then sit at the consultation table for ninety minutes because that seat sets the ceiling, and ask the designers after a normal week rather than a good one. The direction of every adjustment in this guide is knowable. The figure is not, and I will not invent one - SOSA has measured no humidity percentages, no temperature curves and no seasonal multipliers, and a supplier who offers you any of those has made them up. On hardware, climate changes nothing and cubic volume changes everything: under about 750 sq ft the honest buy anywhere in India is one SOSA Sukoon at ₹1,899 or a Mountain Breeze reed at ₹849, and a Vaayu would be the wrong purchase; from roughly 1,500 sq ft, one SOSA Vaayu at ₹11,999, waterless, key-locked, low. If you are planning several branches, note that SOSA does not currently sell a cold-air refill oil separately - the 400ml supplied runs 90+ days a fill and continuity of supply must be confirmed with us in writing before you build a rollout on it. And plainly: no one can promise you that ambient scent moves footfall, enquiries or order value, and a supplier who offers you a figure is selling. Ask for a retail scenting plan and send the floor plans.
Same fragrance in every Indian city, a different number in every showroom. Humid air holds it, dry air delivers it, and both push the dial down from a naive start. The direction is knowable and the figure is not - so you find it by walking in from the street, not by reading a chart.
The machine does not change with the climate, only with the volume. From about 1,500 sq ft, one SOSA Vaayu - waterless, rated to 1000m³, with adjustable intensity and a key-lock, which together are what let one profile run at a different honest number in every branch. ₹11,999. Under 750 sq ft, a Sukoon at ₹1,899.

The ladder is national. Cubic volume decides which row you are on, and the climate decides nothing about it at all.
Any city, from about 1,500 sq ft
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - roughly 2,000-3,000 sq ft at a normal ceiling. 400ml tank running 90+ days a fill, Bluetooth app with 1h/4h/8h/24h timers, adjustable intensity, under 38dB, 5W, auto-stop and key-lock. The adjustable intensity and the key-lock are what allow one profile to run at a different honest number in every branch.

Any city, under about 750 sq ft
SOSA Sukoon
Ultrasonic cool-mist diffuser covering roughly 270-320 sq ft, supplied with three 15ml fragrances. In a humid city or a dry one, this is the honest buy for a single-room studio, and a Vaayu at six times the price would be rated for several times the volume you have.
From ₹1,899
The three things climate actually changes
None of them is the fragrance, and only one of them is really about the weather rather than about the doorway.
1
Humid: it holds
A heavier medium keeps what you put into it
In damp air the same output disperses more slowly and hangs about, so a level found in a dry month arrives as too much in a wet one. The instinct in wet weather runs the other way - everything feels damp, so the fragrance must be losing and needs help - and that instinct is how a coastal showroom ends up running its monsoon number into the following spring. The honest coastal adjustment is downward, taken deliberately, with the date written beside it so somebody puts it back. This is also the clearest case for stating a plain machine fact: the Vaayu is waterless and adds no moisture of its own to the room. That is a statement about the machine and not a claim about your stock or your finishes.
Tip: Write the date beside every seasonal change, or the change becomes permanent.
2
Dry: it delivers
A clearer medium carries further and hides less
Dry air does not dilute a fragrance, it presents it: further across the floor, and with its edges intact. Owners in dry cities read that as thinning and turn the dial up, when the honest move is a step down from whatever a coastal branch of the same brand runs. A clear medium also exposes a wrong register faster, which is why the edible instinct - tempting in every kitchen showroom in the country - is riskiest inland: a sweet note does not settle into the background, it announces itself at the door. The compensation people reach for is warmth, and dry woods supply that honestly by extending what the timber displays are already doing, with nothing from a menu in it.
Tip: A setting borrowed from another branch is almost always a step too high.
One Mountain Breeze reed diffuser ₹849, set once and left alone, is the whole hardware side of this.

3
Conditioned: it converges
Two air-conditioned showrooms are more alike than either is like its own street
This is the fact that quietly settles the argument. Once the doors are shut and the plant is running, the plant dries the air, moves it and holds the room somewhere near the same place all day - which is why an air-conditioned Mumbai display floor and an air-conditioned Jaipur one are far more similar to each other than either is to the pavement outside it. So the variable your dial is really answering is not the climate; it is the size of the step your customer takes on the way in, and how fast the room recovers between one door opening and the next. That is why a genuinely seasonal building needs two numbers, a stable one needs one, and every one of them is found in the doorway rather than on a chart.
Tip: Judge the room from the threshold, in the state it is actually in that day.
The SOSA principle
Every air-conditioned showroom in India is converging on the same room, so what differs from city to city is not the air inside but the size of the step a customer takes to get into it - and that step, rather than the climate, is what your setting is really answering.
Which is why the honest instrument in this whole family is a pavement, a door and one careful breath.
The rule, condition by condition
Nine city pages, one table. Every row states a direction and none of them states a figure, because the figures do not exist.
The SOSA plan
One profile, one number per showroom - the direction by condition
| The condition outside | What to do |
|---|---|
|
Humid and coastal
|
The same setting reads heavier and hangs, so the wet-season number goes down, deliberately, with the date recorded beside it. |
|
Dry inland heat
|
Dry air carries further and delivers more distinctly, so the number goes down again - and a setting borrowed from a coastal branch is a step too high. |
|
Mild and stable all year
|
One number, found once and recorded. The failure mode here is drift rather than season, so the discipline is the card and the key-lock. |
|
Genuinely seasonal, sealed then open
|
Two numbers on one card with the months against them, changed on a chosen date rather than on the first uncomfortable afternoon. |
|
Dusty
|
Clean the displays and service the air-conditioning filters first. Stalled airflow reads exactly like a faded fragrance, and no dial fixes a filter. |
|
Unconditioned, frontage open
|
The air exchange sets the ceiling and the dial cannot raise it. Close the one room you want to be consistent, and spend ₹1,899 rather than ₹11,999. |
The two mechanisms in this page each have a city page of their own, and they are worth reading as a pair: the humid case, in Mumbai, where damp air holds a fragrance and the wet-month number comes down, and the dry case, in Ahmedabad, where clear air delivers it sharply and the number comes down for the opposite reason. SOSA is independent and not affiliated with any hotel.
One profile, one number per showroom
SOSA Vaayu ₹11,999 covers up to 1000m³, and its adjustable intensity is what lets one brand run honestly in ten different cities.
If a supplier hands you a humidity percentage and a seasonal adjustment to go with it, ask which showroom they measured. They did not measure yours, and nobody has measured mine either - which is why this whole family sends you to your own doorway instead.

Fix the profile centrally, set the number locally, and record both. Ambient scent here is a presentation decision like lighting or display styling; it is never used to mask another smell - not laminate, not adhesive, not dust, not cooking - and it is never a substitute for ventilation, extraction or cleaning. Seasonal figures, humidity percentages and adjustment multipliers are not published by SOSA because they have not been measured. And plainly: no one can promise you that ambient scent moves footfall, enquiries or order value, and a supplier quoting you a figure is selling. Ask for a retail scenting plan before you spend anything.

A note from Sonal
I get asked this most often by owners running two or three showrooms in different cities, and the fear behind the question is always the same: that they will have to keep several fragrances, one for the coast and one for the interior, and that the brand will quietly stop being one thing. They do not, and it will not. The profile is a brand decision made once, from your displays and your price point. The number is a building decision made in every building. That is the entire rule, and the nine city pages under this one are just instances of it.
What the climate actually does is worth understanding, because it stops you guessing. Damp air is a heavier medium and holds what you put into it, so a coastal showroom's wet-season number comes down even though the weather makes you feel it should go up. Dry air is a clearer medium and delivers with the edges intact, so an inland showroom's number comes down too, for the opposite reason, and a setting borrowed from a coastal branch is almost always a step too high. And then the fact that quietly ends the argument: once the doors are shut and the plant is running, an air-conditioned display floor in Mumbai and one in Jaipur resemble each other far more than either resembles its own street. So what your dial is really answering is the size of the step a customer takes on the way in - which is why every page in this family sends you to the pavement rather than to a chart.
Which is also why I will not give you a percentage. SOSA has measured no humidity figures, no temperature curves and no seasonal multipliers, and I would rather say that than publish something invented. On hardware, the ladder is national: under 750 sq ft a Sukoon at ₹1,899 or a Mountain Breeze reed at ₹849, from about 1,500 sq ft a Vaayu at ₹11,999, and past roughly 5,000 sq ft an Aangan at ₹25,999. Before a multi-city rollout, be aware that we do not currently sell a cold-air refill oil separately and confirm continuity of supply with us in writing. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Does a kitchen showroom need a different scenting strategy in humid vs dry Indian cities?
No. The strategy is the same everywhere and only the number changes. One dry, material-led profile chosen from your displays and your price point, with nothing edible in it, held at a low level on a trading-hours timer. Humid air holds a fragrance and lets it hang; dry air carries it further and delivers it more distinctly. Both of those point the setting downward from a naive starting point, and neither of them changes which fragrance you should be running.
How much should I adjust the setting for humidity?
Nobody can tell you, and anyone who quotes a percentage has invented it. SOSA has measured no humidity figures, no temperature curves and no seasonal multipliers, so the honest output is a direction rather than a number. Find the figure yourself by standing outside for a few minutes, walking back in through the customer's door and judging the first breath, then sitting at the consultation table for a full ninety minutes. Record what you settle on, with the date.
Why do both humid and dry cities end up with a lower setting?
For opposite reasons that meet at the same instruction. In damp air the medium is heavier and slower, so the same output hangs about and arrives as more than you intended. In dry air the medium is clearer, so the same output travels further and arrives with its outline intact. In practice the mistake in a wet city is raising the dial because the room feels damp, and the mistake in a dry one is raising it because the fragrance seems to be thinning out. Both are the wrong direction.
Should each branch of my brand run a different fragrance for its climate?
No, and doing so would cost you the one thing a signature is for. Keep the profile fixed centrally so that a customer who visits two branches recognises the same room, and set the intensity locally so that each showroom is honest about its own volume, doors and air handling. Write the number, the timer windows and the machine position on a card in each branch, turn the key-lock on, and audit them on foot rather than by phone.
Does the machine itself need to change between a humid city and a dry one?
No. Climate has no bearing on which machine you buy; cubic volume does. Under about 750 sq ft the honest answer anywhere in India is a Sukoon at Rs 1,899 or a Mountain Breeze reed at Rs 849, and a Vaayu would be the wrong purchase. From about 1,500 sq ft it is one Vaayu at Rs 11,999, and past roughly 5,000 sq ft with central air handling an Aangan at Rs 25,999. Measure length by width by height in metres before deciding.
