Here is the distinction that decides the page. Your managed office almost certainly has out-of-hours access, a security desk, lights on a sensor and an app that lets a member swipe in at midnight. None of that is occupancy. Occupancy is people in a volume, and between 8 PM and 8 AM the honest headcount on most floors is a handful: a few late members finishing something, a security presence, a housekeeping team coming through, and nobody else. There is no arrival experience at 2 AM. Nobody is walking into your reception at two in the morning and forming an impression of the space, which is the only thing an ambient register in an arrival area is honestly for. You are scenting an empty room, on a schedule set by a lock rather than by a person.
The published Bluetooth app and timer on the SOSA Vaayu at ₹11,999 is exactly the feature that solves this, and I would argue it is the single most valuable thing an operator is actually buying. Not output. A schedule. A unit that runs when the floor is occupied and stops when it is not, held in software rather than in somebody's memory, is the difference between a considered building and a machine left on.
Then the part that most pages would leave out, and it is the honest core of the argument. The few people who are in the building late are the most exposed people per head in it. A weekday level is calibrated against a room full of people arriving and leaving, receiving it for a few minutes each. At 10 PM that same level is being delivered to three people who cannot go anywhere else, for hours, in a room with fewer bodies and fewer opening doors to stir the air. The late-shift arithmetic argues for less, not more, every single time - and it is the argument I would make even to an operator who told me cost was no object.
Two things I will not tell you to do, because they are the two most common bad answers in this category. Never run short high bursts to top the room up - a burst is a spike delivered to whoever happens to be standing there, and it is the opposite of a calibrated level. And never leave a unit running overnight so the floor is ready in the morning; a still floor accumulating for ten hours is not ready, it is loaded, and the first people through the door receive all of it. Fragrance adds scent and does not remove odour, no SOSA product treats, filters, dries or purifies air, and there is no claim here about what a scent does to anyone or about leasing, occupancy, retention or any business result - the ceiling is improved evaluations of a space and its service, longer dwell and stronger recall, at moderate effect sizes.
What about the few people who are still there late? They are the strongest argument for turning it down, not up. A weekday level is calibrated against a room full of people who each receive it for a few minutes on the way through. At 10 PM the same level is delivered to a handful of people who are stuck with it for hours, in a room with fewer bodies and fewer opening doors to stir the air. Per head, the late team are the most exposed people in the building. Anyone on duty should be able to switch a named unit off without asking a manager and without justifying it, and a reported reaction is a recalibration signal rather than a tolerance problem.
Should I run short bursts overnight to keep the space ready? No. A burst is not a calibrated level - it is a spike delivered to whoever happens to be standing there when it fires, usually a security guard or a cleaner. And a floor is not made ready by accumulating overnight; a still, closed volume with reduced air movement collecting output for ten hours is loaded rather than prepared, and the first people in receive the whole of it. If you want a good morning, run the schedule up shortly before the floor fills and let the arriving crowd, the opening doors and the lift traffic do the mixing for you.
Draw the curve honestly, because most operators have never written it down. A typical managed floor fills through the morning, peaks in the middle of the day, holds through the afternoon, thins from about six, has a long thin tail into the evening and is effectively empty from somewhere between nine and eleven until the first people arrive the next morning. Housekeeping comes through at some point, security is present, and that is the population. Now map the value of an ambient register against that curve. It is doing real work at the front of the day, when members and their visitors are arriving from outside and receiving the largest contrast anybody gets. It is doing real work through the day in a reception and client-facing volume where guests are received. It is doing progressively less in the evening tail. And between midnight and six it is doing nothing whatsoever except being breathed by a security guard.
So the schedule writes itself, and the app holds it. On through the occupied hours at your calibrated level. Reduced through the evening tail, because the people left are staying longer and there are fewer of them. Off overnight. And then up again shortly before the floor fills, not at four in the morning - because a room is not improved by ten hours of accumulation, it is loaded by it. The SOSA Vaayu at ₹11,999 publishes a Bluetooth app and timer, and I want to be plain that this, rather than any number about output, is what an operator is buying. Anyone can put a machine in a lobby. A schedule that follows the occupancy curve, set once, written down and not nudged by whoever is on the desk at nine in the evening, is what makes the difference between a building with a character and a building with a device in it.
Now the exposure argument, which I would make even if the schedule cost nothing to run. Whatever level you set is calibrated against the daytime room: a large volume, several hundred people, doors cycling, lifts running, a crowd stirring the air continuously, and each individual receiving the level for a few minutes as they pass through the arrival area. The night version of that room has none of it. Fewer bodies, fewer opening doors, less mixing, and in many buildings a reduced air handling pattern outside core hours - which is your facilities team's information rather than mine to assume, and which I will never suggest anybody change so that a fragrance lasts longer. Into that slower, stiller room you are delivering the daytime level to three or four people who are there for hours and cannot go anywhere else. Per head, the late staff and the late members are the most exposed people in your building. They are also, being a small group with no colleagues to compare notes with, the least likely to say anything. That is the whole case for less, and it is a case about people rather than about cost.
And the two things never to do. First, no bursts. The idea that a short high burst tops a room up is one of the most persistent bad ideas in ambient scenting, and it fails on its own terms: a burst is not a level, it is a spike, and the person who receives the spike is whoever happens to be standing near the unit when it fires - overwhelmingly a security guard or a cleaner, night after night. If a room needs a level, give it a level, low and continuous, during the hours people are in it. Second, no overnight running for a good morning. A closed floor with reduced air movement collecting output from eleven at night to eight in the morning does not present better at nine; it presents as a room somebody left something running in, and in Pune between June and October, when indoor humidity peaks in July and August and a closed floor is already still and damp, it presents considerably worse than that. Fragrance over a stale, damp room gives you a stale, damp room with a register on it. The morning answer is airing, cleaning and a schedule that starts shortly before the crowd, not accumulation. A portion of every SOSA order supports girl-child education through Nanhi Kali.
If you do one thing this week, get the actual overnight headcount rather than the assumed one. Access control logs, the security register, the housekeeping rota: between them you can put a real number against every hour from 6 PM to 8 AM, and almost every operator who does this is surprised by how fast the curve falls after about half past seven. That number is the entire basis for the schedule, and it takes an afternoon to produce.
Then check what is actually running at eleven at night, which is a different question from what you think is running. Walk the floors, or ask security to note it. In my experience the machine is one of several things running for nobody - lighting in a zone with no sensor, a coffee machine left on, a television in a breakout area, a room booked and never cancelled. The fragrance schedule is the easiest of those to fix because it is a setting in an app rather than a wiring job.
Ask the late team directly, and make it easy to answer. Not a general question about whether the office smells nice, which people answer politely, but a specific one: at ten at night, is the level right, too much, or would you rather it was off? Ask the security guard who is there every night, and ask the housekeeping supervisor, because those two people have more hours of exposure to your building's air than any member does and they are almost never consulted. Make it a named standing arrangement: anyone on duty can switch a named unit off without asking a manager and without justifying it. Write it into the operations procedure, tell the night team it exists, and treat any report as a recalibration signal rather than a tolerance problem. No health or allergy claim is made in either direction, and nobody should ever be addressed about how they personally smell.
Then think about which volumes, not just which hours. In a managed office the evening population is usually concentrated - two or three people in one corner of one floor - while the reception, the event space, the client meeting rooms and three other floors are genuinely empty. A schedule that turns everything down at eight is better than one that turns nothing down, but a schedule that scents only what is in use is better still. And a doored meeting room left running overnight is the worst case in the building: a small volume, roughly 57 cubic metres at 200 sq ft and a 10 ft ceiling, with nothing moving through it, collecting for ten hours. The first meeting of the day walks into all of it.
One last framing that settles most internal arguments. The question is not whether the building is open. It is how many people are in the room and for how long. Answer that hour by hour and there is nothing left to debate.
Accessible is not occupied, and there is no arrival experience at 2 AM
Three things decide this, and the machine's capability is not one of them. The first is the difference between access and occupancy, which in managed workspace is the whole confusion. The second is exposure: who receives the level at ten at night, and for how long. The third is scheduling as an operational discipline rather than a feature - which volumes, which hours, written where, changed by whom.
What does not decide it is readiness. The belief that a space needs to be held at a level overnight so that it is right in the morning is intuitively appealing and factually backwards. A still room with reduced air movement accumulates; it does not ripen. The morning experience is made by the arrival curve itself - people coming in from outside, doors cycling, lifts running, a crowd mixing the air - and by a schedule that comes up shortly before them. Not by ten hours of output delivered to nobody.
Do the arithmetic once, because it explains why an overnight schedule costs more than an operator expects in more than one sense. A managed floor of 5,000 sq ft at a 12 ft ceiling is 5,000 multiplied by 12, which is 60,000 cubic feet, and 60,000 divided by 35.3 is about 1,700 cubic metres. A 10,000 sq ft floor at 12 ft is 120,000 cubic feet, about 3,400 cubic metres. A 2,000 sq ft reception and lounge at 12 ft is 24,000 cubic feet, about 680 cubic metres. A 200 sq ft meeting room at 10 ft is 2,000 cubic feet, about 57 cubic metres. Against a Vaayu published for approximately 1000 cubic metres of connected air, a large floor plate is a volumes-and-placement problem rather than a strength problem - and each of those volumes is a separate scheduling decision, which is precisely why "should it run at night" is really several questions with several answers.
The Kharadi context is doing real work here rather than decorating the page. This is a young, large-format, campus-scale district in Pune's eastern corridor - a village until around 2005, developed exponentially through the 2010s and continuing through the 2020s - and it is one of the three localities that between them hold 43 per cent of Pune's total office supply. It is also a market where flexible workspace operators led demand in the most recent quarter, with Pune gross leasing at 3.22 msf in Q2 2026 and global capability centres contributing over half of it. Managed and flexible space is therefore not a niche here; it is the shape of the market, and the operator running a floor with round-the-clock access and a twelve-person evening population is an extremely common reader. What I will not do is convert that into a claim that offices in this district run shifts or operate around the clock as a matter of fact. You have told me your building is accessible late. I am answering your building, not the district.
Managed workspace confuses this more than any other building type, and it is not the operator's fault. The product is availability. Members are sold twenty-four hour access, the card works at any hour, the lights come up on a sensor, security is present, and the building genuinely never closes. That creates an instinctive expectation that the space should also be presented at any hour, which is a reasonable-sounding leap and a wrong one. Presentation is for people. A lobby with nobody in it does not need to be presented, and a corridor at three in the morning is not making an impression on anybody.
Draw your own curve and the argument ends. Take a fortnight of access logs and plot headcount by hour. Most managed floors in this market show a steep climb from about nine, a broad plateau through the middle of the day, a decline from around six, a thin tail to somewhere between nine and eleven, and then a flat line of two to five people until the morning. Overlay the fragrance schedule you currently run. If the schedule is flat and the curve is not, you are paying to scent a flat line of empty hours and delivering that output to the smallest and most exposed group in the building.
Now the subtler point, which is about which volumes rather than which hours. The evening population of a managed office is not spread evenly. It concentrates: two members in one pod on the third floor, a team finishing something in one meeting room, security at the ground floor desk. Meanwhile the reception, the event space, the client meeting rooms, the lounge and several other floors are genuinely empty. A single overnight off-switch is a large improvement over nothing. A schedule that scents only what is in use is better, and in a multi-floor managed building it is entirely achievable, because the volumes are already separate - a closed door ends one connected body of air and begins another, and at eleven at night most of your doors are closed.
And the worst case in the building, which is worth naming explicitly. A doored meeting room with a unit left running overnight is a small volume - about 57 cubic metres at 200 sq ft and a 10 ft ceiling - with nothing passing through it, collecting output for ten or twelve hours. It is not ready in the morning. It is the most over-scented room you own, and the nine o'clock meeting receives the entire night in the first thirty seconds. If there is one schedule to fix before any other, it is that one.
The night room shares none of those properties. Fewer bodies, so far less mixing. Fewer doors opening, so far less exchange between volumes. Nobody arriving from outside, so nobody getting the contrast that the level was designed to deliver. And in many buildings a different air handling pattern outside core hours, which is information that belongs to your facilities team rather than to me, and which I will never suggest anybody change so that a fragrance reads stronger or lasts longer. Ventilation wins, always, in every phrasing.
Into that room you are delivering a daytime level to a handful of people for hours. A security officer on a twelve-hour position is in that air for twelve hours. A housekeeping team works through several floors of it. Two members finishing a deadline are in one pod for four hours with the doors shut. Per head, these are the most exposed people in your building by a wide margin, and the exposure is concentrated in exactly the group least likely to raise it: contracted staff, a small headcount, no colleagues to compare notes with, and in many cases no obvious person to tell.
So make it a standing arrangement rather than a favour, and write it down. Anyone on duty at any hour can switch a named unit off without asking a manager and without justifying it. Name the units so a report can be specific. Put it in the operations procedure alongside the lighting and the access rules. Tell the night team it exists, and tell the security contractor and the housekeeping contractor too, because they are not on your internal channels. Treat any report as a recalibration signal rather than a tolerance problem - the level comes down or the unit goes off that day. I make no health or allergy claim in either direction, and nobody should ever be addressed about how they personally smell.
And be realistic about noses, including your own. Anybody who has been in a building since morning has adapted and cannot report its level to you. That includes you, your community team and your operations manager. It does not include a member arriving at eight in the evening from outside, and it does not include a security officer coming on shift at ten. Those are the two most valuable opinions available to you and they cost nothing to ask for. If you want one number to act on, ask the person who has just walked in - every time, in every building, at every hour.
The same logic caps the daytime level too. Your community team, your front-desk staff and your cleaners are in that air eight to ten hours a day, five or six days a week, which is many times any member's exposure and very many times any visitor's. They are the cap on the level for the whole building, and a level that is comfortable for somebody walking through for ninety seconds may not be a level anybody should sit in all day. When in doubt, down.
Then the volumes, because hours alone are half a schedule. In a multi-floor managed building, an empty floor gets nothing regardless of the hour. A doored meeting room gets nothing overnight, and arguably nothing at all - it is the smallest volume, the longest dwell and the least ventilated space you operate. An event space that is used twice a week gets a schedule tied to bookings rather than to the clock. The reception is the volume that earns a standing schedule, because it is the only one whose entire purpose is people arriving.
The two things never to do, repeated because they are the two things I am asked about most. No short high bursts to top a room up. A burst is a spike, not a level; it lands on whoever is standing near the unit at the moment it fires, which overnight is a guard or a cleaner, night after night; and it teaches nobody anything about how the room should smell. If a volume deserves a level, give it a low continuous one during occupied hours. And no overnight running for a good morning. A still, closed floor collecting output for ten hours is loaded rather than ready, and in a Pune monsoon month - roughly June to October, with indoor humidity at its annual peak in July and August - a closed floor is already still and damp, so what you get at nine in the morning is damp and fragrance rather than a considered arrival. Most people find that combination worse than the damp on its own, which is why the instinct to add in a wet month is precisely the wrong instinct.
What the app is genuinely worth, stated as a feature rather than a promise. The SOSA Vaayu at ₹11,999 publishes a Bluetooth app and timer. That is a published specification and it is the thing that turns everything above from a policy into how the building runs. Settings in an app are settings that survive a change of duty manager, that can be audited, and that do not drift upward because somebody turned a dial on a bad morning. The rest of the published specification: waterless cold-air nebulising of undiluted oil so no water, no humidity and no wet residue, approximately 1000 cubic metres of connected air, SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly, a 400ml tank, freestanding or wall and HVAC mounting, DC 12V / 1A at 5W so it needs a live socket, and CE, RoHS and SGS.
And the honest limits, because an operator will ask about running cost and deserves a straight answer. SOSA does not publish consumption rate, refill frequency, monthly running cost or machine lifespan, so this page will not state any of them and you should be suspicious of any page that does without a source. What I can tell you plainly is what genuinely drives the first three: how many hours the unit runs, how large the connected volume is, what level it is set to, and how many separate volumes you are scenting. Every one of those is a reason to schedule honestly rather than a reason for me to invent a number. If you want the specifics for your building, that conversation happens on WhatsApp at +91 96192 18531 rather than on a blog page.
- Plot real headcount by hour from access logs, security register and housekeeping rota.
- Lay your current fragrance schedule over that curve and mark every empty hour.
- Set the app: up before the fill, calibrated by day, reduced in the tail, off overnight.
- Name the units, and let anyone on duty switch one off without asking a manager.
The schedule that follows the occupancy curve, and the two things never to do
The register does not change with the hour. The level and the schedule do. That is worth saying plainly because the commonest request I get from operators is for something lighter at night, and a lighter register at night is a worse answer than the same register at a lower level - it means your building smells like two buildings, and the thing ambient scent honestly does is make a space recognisable.
One register, held, at three levels and across two seasons. Out of the seven in the water-based Hotel Collection - each SOSA's own hotel-inspired interpretation, with SOSA independent and not affiliated with, endorsed by or connected to any hotel brand - the corporate shortlist is narrow and the reasoning is context rather than taste: dry, clean, unsweet, low, and identical every day.
Quiet Luxury is white tea, bergamot and cedar, hushed and polished, and it is the managed-office default given one decision and no information about the building. It holds a small presence across a large arrival volume without becoming the thing anybody thinks about, which is the correct test for a space the same members walk through twice a day. Forest Suite is cedarwood, vetiver and green leaves, grounding and green, and the driest of the shortlist - which matters specifically on this page, because dry recedes where sweet accumulates, and accumulation is the exact failure mode of a still overnight floor. If you are worried about what the room is like at seven in the morning, dry is the direction. White Tea Serenity is white tea, aloe and cedar, clean and weightless and spa-like, reading as clean rather than as scented, which suits a pale, minimal managed fit-out where anything with weight would sit oddly against it.
The ones I would keep out of a managed office. Lobby Bar is citrus, pepper and amber, bold and playful and after-dark, and the after-dark part is the trap - it sounds like the answer to an evening question and it is not, because the people present in the evening are working rather than socialising and they are there for hours. Old-World Glamour is amber, violet and woods, plush and evening-elegant, and plush is what accumulates in a still volume overnight. Warm Welcome is citrus, floral and sandalwood, a genuine hotel-threshold register and a real argument for a hotel lobby, but a managed office is not a place people arrive at once - it is a place the same people arrive at every day, and threshold registers wear differently on the ninetieth arrival than the first. Tea Garden is jasmine, green tea and white tea, the least risky floral in the collection because the jasmine sits inside the tea; I would still keep floral weight off a floor where people work all day and have no say in it.
I will not rank the seven against each other on measured throw or longevity. SOSA does not publish that comparison, and the variables that dominate - connected volume, ceiling height, how hard the building is working its air at that hour, how many people are present and where the unit sits relative to a supply grille - belong to your building rather than to the blend.
The levels, then, written into the app rather than remembered. Occupied hours at your calibrated daytime level, in the reception and connected client-facing volume only. Evening tail at a reduced level over a shorter window, covering only what is in use. Overnight off. Closed day off. And underneath those, two seasonal levels: one for the monsoon months of roughly June to October, when the floor is closed up, humid and slow and indoor humidity peaks in July and August, and one for the dry heat of mid-March to mid-June, when the air conditioning is working hard against average highs near 37.9 degrees C in April and the air is turning over faster. Change them deliberately at the season change and write the date. The failure this prevents is the quiet upward drift that happens in every building where the level is adjusted by whoever is standing nearest.
Placement, last, because it is free and beats output nearly every time. A unit sitting in a supply airstream has its output picked up, carried away and thinned before the room receives it; a unit in a dead corner behind a planter never reaches the room at all. On a large-format floor with numerous supply grilles this is a bigger effect than it is in a small unit. If your reception reads well at the desk and vanishes eight feet away, move the unit before you touch the setting, and move it out of the airstream and away from the mouth of any corridor you do not intend to scent.
| Scent | Why it suits the mood |
|---|---|
| Occupied hours · reception and client-facing volume, calibrated level | One register - Quiet Luxury, Forest Suite or White Tea Serenity - held at the level you set for the visitor waiting twenty minutes rather than the one walking in. Only in the volumes that are in use, and only in the hours the floor is genuinely occupied rather than the hours the doors unlock. |
| Evening tail · reduced, and only where people actually are | Same register, lower level, shorter window. The evening population is small, concentrated and staying for hours, and per head it is the most exposed group in the building. Fewer bodies and fewer opening doors also mean less mixing, so the same output reads higher than it does at noon. |
| Overnight · off, including every doored meeting room | Off, not low. There is no arrival experience at 2 AM. A doored room of about 200 sq ft at a 10 ft ceiling is roughly 57 cubic metres with nothing moving through it, so ten hours of output is not readiness - it is the whole night delivered to the nine o'clock meeting in the first thirty seconds. |
| Never · bursts, and overnight running for a good morning | A short high burst is a spike rather than a level, and it lands on whoever is standing near the unit when it fires - overnight, a guard or a cleaner. And a still floor does not ripen, it loads. Bring the schedule up shortly before the floor fills and let the arriving crowd and the cycling doors do the mixing. |
So the buying answer, and for an operator it is unusually clear: you are buying a schedule. The waterless SOSA Vaayu at ₹11,999 publishes a Bluetooth app and timer, and that is the feature that makes every recommendation on this page something a building actually does rather than something an operations manager intends. The rest of the published specification is cold-air nebulising of undiluted oil so no water, no humidity and no wet residue, approximately 1000 cubic metres of connected air with SOSA's own copy also stating 2,000 to 3,000 sq ft scented evenly, a 400ml tank, freestanding or wall and HVAC mounting, DC 12V / 1A at 5W so it needs a live socket, and CE, RoHS and SGS. On a large floor plate it is a volumes-and-placement proposition rather than a one-machine one, which is a reason to plan zone by zone rather than to buy a bigger number.
For a single doored room - one client meeting room, one small lounge - do not buy the same machine again. An ultrasonic is usually the whole purchase: a Boond at ₹899 or a Sukoon at ₹1,899, running the water-based Hotel Collection from ₹299 with 100ml refills at ₹999 and 300ml also available; the pack of seven 15ml bottles at ₹1,799 is the sensible way to audition registers in your own air rather than from a description. Two systems, and they are not interchangeable: the ultrasonics are water-based cool-mist machines, while the Vaayu and the ducted machines - Aangan at ₹25,999 for approximately 8,000 to 10,000 sq ft and Meenar at ₹38,500 for approximately 12,000 to 18,000 sq ft - run waterless nebulising oil. The ₹299 water-based bottle never goes into a Vaayu or an HVAC machine. In a Pune monsoon month there is a plain design reason to prefer the waterless machine: the ultrasonics put a small amount of moisture into the room they sit in, and a closed, still, humid floor is the wrong place for that. A design preference, never a claim to control humidity, dehumidify or protect anything, because no SOSA product does.
And there is an honest answer that involves no schedule at all. If what you want in a small lounge or on a reception counter is no plug, no noise, no app and nothing to switch off at eleven at night, the SOSA reed diffusers are their own registers rather than Hotel Collection ones: Mountain Breeze ₹849 is Himalayan pine, sage and cedar; Morning Freshness ₹749 is Malabar lemon, mint and eucalyptus; Garden Bloom ₹799, Evening Calm ₹799 and Fresh Brew ₹849 complete the set. 130ml from ₹1,249, refills at ₹2,399 and ₹3,499, lasting about 6 to 10 weeks. A reed is passive and local: it scents the few feet around it and will not fill a floor, which is a limitation everywhere else and, for an operator who simply wants the front desk to have a character without an overnight question attached to it, occasionally the whole answer.
To go deeper on what this page only touches: the weekday and weekend version of the same argument, including what a quiet day is genuinely for, is in how fragrance settings should change between a busy Kharadi weekday and a quiet weekend. If some of your volumes never seem to receive anything at all whatever the schedule says, the mechanism is explained in why a Kharadi office reception scents well while the meeting rooms stay neutral. And if the deeper brief is that the space should feel like somewhere in particular, most of that answer is not fragrance, which is the argument in making a premium Kharadi office feel different from every other glass-and-AC corporate office.
What SOSA does not publish, and what this page will therefore not invent: consumption rate, refill frequency, monthly running cost, machine lifespan, minimum order quantity or installation lead time. Run hours, connected volume, setting and the number of volumes are what genuinely drive the first three, which is a reason to schedule honestly rather than a reason for me to quote a figure I do not have. Send your floor plan, ceiling height, real headcount by hour and the volumes actually in use in the evening to SOSA on WhatsApp at +91 96192 18531. Bulk orders are welcome, custom label or logo on product is available, and bespoke composition is a real SOSA service discussed there rather than priced on a page - although the cheaper honest answer comes first, which is that one of the seven registers held consistently already is a signature, because consistency makes a signature and uniqueness does not.
The SOSA scenting range
SOSA sells two different systems and one of the commonest mistakes is mixing them up. Size by the connected air volume of the room you are actually scenting - which in a boutique means the connected retail floor plus any viewing room that has a door of its own - floor area multiplied by ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres. A door that stays shut ends one volume and begins another.
| Machine | System | What it is for | Price |
|---|---|---|---|
| SOSA Boond | Ultrasonic · water-based | A small desk or corner unit for one enclosed room - runs the water-based Hotel Collection | ₹899 |
| SOSA Sukoon | Ultrasonic · water-based | A larger ultrasonic for a reception or consultation room - Hotel Collection from ₹299 | ₹1,899 |
| SOSA Megh | Ultrasonic · 6L tank | A large-tank ultrasonic for a bigger lounge that runs all day | ₹3,499 |
| SOSA Vaayu | Waterless cold-air nebulising | The commercial machine - approx 1000 m3 of connected air, Bluetooth app and timer, no water and no humidity | ₹11,999 |
| SOSA Aangan | HVAC nebulising | Ducted scenting for approximately 8,000 to 10,000 sq ft | ₹25,999 |
| SOSA Meenar | HVAC nebulising | Ducted scenting for approximately 12,000 to 18,000 sq ft | ₹38,500 |
Two systems, and they are not interchangeable. The ultrasonics - Boond, Sukoon and Megh - run the water-based Hotel Collection from ₹299. Vaayu and the HVAC machines run waterless nebulising oil; the ₹299 water-based bottle never goes into a Vaayu. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is independent and not affiliated with any hotel brand. A portion of every order supports girl-child education through Nanhi Kali.
- Vaayu ₹11,999 - waterless cold-air nebulising, approx 1000 m3 connected air, Bluetooth app and timer, 400ml tank, freestanding or wall / HVAC mount, DC 12V / 1A, 5W, mains powered, CE / RoHS / SGS.

SOSA is a Pune business, so these are not pages I wrote from a desk somewhere else. I have stood in a Baner clinic in the second week of July and in a Kharadi tower in the middle of April, and the useful thing I can tell you is this: the locality on your signboard is not a technical variable. Nobody scents a postcode. What a locality name is actually shorthand for is a cluster of real things - how old the building is, whether the front is sealed glass or a door onto a pavement, what the air conditioning genuinely is, how many people come through, how long each of them stays, and what the room already smells of.
Which is why two businesses three doors apart can need completely different answers, and why the same business needs two different answers in July and in April. A Pune monsoon room and a Pune April room are not the same room. One is damp, closed up and slow; the other is dry, hot, and running its air conditioning so hard that whatever you put in the air is being moved and diluted faster than you think. That is a real difference and it belongs in the settings, not in the choice of blend.
The order never changes, though, and it is the least commercial thing I say: source, then ventilation, then cleaning, then fragrance. Fragrance adds a smell. It has never once removed one. If your unit smells of damp, or new paint, or last night's food, a machine will give you damp and fragrance - and most people find that worse than damp. Fix the thing making the smell, get air moving, clean what holds it, and then, if the room deserves it, give it a quiet character and hold it.
Frequently asked questions
Facts verified September 2026: SOSA Vaayu ₹11,999 is a waterless cold-air nebulising diffuser rated for approximately 1000 m3 of connected air, with Bluetooth app and timer, a 400ml tank, freestanding or wall / HVAC mounting and a DC 12V / 1A, 5W mains supply. SOSA Aangan ₹25,999 covers approximately 8,000 to 10,000 sq ft and SOSA Meenar ₹38,500 approximately 12,000 to 18,000 sq ft, both ducted into HVAC. The ultrasonic machines - Boond ₹899, Sukoon ₹1,899 and Megh ₹3,499 - run the water-based Hotel Collection fragrance from ₹299, with 100ml refills at ₹999; that water-based bottle is not used in a Vaayu or an HVAC machine. Reed diffusers start at ₹749 and last roughly 6-10 weeks. A coverage rating assumes one connected body of air; scent does not travel through a closed door. Ambient scent research supports improved evaluations of a space and its service, longer dwell and stronger recall at moderate effect sizes - it does not support claims about bookings, fees or retention. Fragrance adds scent and does not remove, neutralise or purify odour, and no SOSA product makes any health, antibacterial or air-purifying claim. No SOSA product is an air-treatment device, an air purifier, a dehumidifier, a humidity-control product or an odour-removal product, and none makes any health, allergy, air-quality or occupational claim. No claim is made here about any effect on a customer, a patient, a purchase, a footfall figure or a business result. Nothing in this guide is clinical, facilities, HVAC, food-safety or building advice: in a clinical space the treating clinician decides what may be in the air, in a food business the kitchen and the applicable food-safety rules decide, and in any building the people responsible for its air and its maintenance decide - and their decision overrides every recommendation here. Descriptions of Pune's seasons and localities are general and qualitative; every figure about a specific building must come from that building. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is independent and not affiliated with any hotel brand. Prices and availability are subject to change - see the live product pages.
