Will a 400ml tank last through a launch event? Comfortably. A 400ml SOSA Vaayu (₹11,999) fill lasts up to about 75 days depending on intensity and run hours, so a four-hour launch event uses a very small fraction of one tank. In practice the fill you put in for the pre-launch testing is still running through the launch and well into the sales gallery period afterwards.
Can guests tamper with a scent machine at a public launch? Not on a SOSA Vaayu (₹11,999) with the key-lock engaged. The key-lock exists for public spaces and fixes the settings so nobody can change the intensity or switch the machine off during an event. Auto-stop handles the tank running dry, and the machine is CE, RoHS and SGS certified, which is usually what a venue safety walkthrough asks to see.

Facts verified 24 August 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 a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, Bluetooth app and onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, DC 12V/1A at 5W, 165 x 80.5 x 215mm and 0.9kg, freestanding or wall and HVAC mounting, auto-stop and key-lock for public spaces, and CE, RoHS and SGS certification, with no water, heat, dampness or residue. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. 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 a fair question and it deserves a specific answer rather than a brochure. Below are the five objections developers and procurement teams actually raise about using a Vaayu at a launch, each answered from the specification, including the one where the honest answer is that you need a different machine.
Quick answers — read this first
Is the SOSA Vaayu suitable for a luxury real estate project launch? Yes, for any launch volume up to about 1000m³, which is roughly 2,000-3,000 sq ft - a launch floor, a registration foyer, a sales gallery or a sample flat. It is waterless, runs under 38dB, holds 400ml lasting up to about 75 days, has a key-lock for public spaces and auto-stop, and is CE, RoHS and SGS certified. At ₹11,999 it is the standard machine for launch-scale spaces. Where a single hall is 8,000-10,000 sq ft, the honest answer is the SOSA Angaan (₹25,999) instead.Will a 400ml tank last through a launch event? Comfortably.

The short answer
Short answer: yes for any launch volume up to about 1000m³, roughly 2,000-3,000 sq ft - the SOSA Vaayu (₹11,999) is waterless, under 38dB, key-locked, auto-stopping, CE, RoHS and SGS certified, with a 400ml fill lasting up to 75 days and Bluetooth plus onboard controls; the honest no is a single hall of 8,000-10,000 sq ft, which is a SOSA Angaan (₹25,999).
The pick: the SOSA Vaayu (₹11,999) for launch floors, foyers, galleries and sample flats up to about 3,000 sq ft each, and the SOSA Angaan (₹25,999) where a single volume is genuinely banquet or marquee scale.

Straight answer
Is the SOSA Vaayu actually the right machine for a luxury project launch?
Yes, with one clear exception. The SOSA Vaayu (₹11,999) is rated to 1000m³, described as roughly 2,000-3,000 sq ft, which covers a launch floor, a registration foyer, a sales gallery or a sample flat - the spaces most launches are actually made of. Taking the objections in the order they usually arrive: Will the tank last? Yes. 400ml runs up to about 75 days depending on intensity and run hours, so a four-hour event consumes a small fraction of a fill, and in practice the tank filled for pre-launch testing is still running weeks later in the gallery. Will it be heard? No. It runs under 38dB, below the air-conditioning noise floor in most halls, and because it is waterless there is no bubbling, misting or hiss to carry into a speech or a live microphone. Can a crowd interfere with it? No. There is a key-lock for public spaces that fixes the settings once engaged, plus auto-stop when the tank empties, and the machine is CE, RoHS and SGS certified, which is normally what a venue safety walkthrough wants to see. Does it depend on the venue's network? No. It runs on a Bluetooth app from a phone in the room, with onboard buttons as a fallback, and the 1h/4h/8h/24h timers hold their schedule without any connection at all - so a venue with no usable wifi is not a problem. Will it damage a hired finish? No. It is waterless, with no heat, no dampness and no residue, and it draws 5W at 0.9kg, so it stands on a plinth without any installation. And the honest no: if the launch hall is a single volume of 8,000-10,000 sq ft, a Vaayu is the wrong tool and adding several of them makes it worse, not better. That is a SOSA Angaan (₹25,999) at 3,000m³. A free scenting plan will tell you which side of that line you are on, and a portion of every order supports girl-child education through Nanhi Kali.
Yes up to about 3,000 sq ft per volume, on tank life, noise, tampering and certification. No for a single banquet-scale hall, which is the Angaan.
The specification, in one line: the SOSA Vaayu covers 1000m³ (about 2,000-3,000 sq ft), holds 400ml lasting up to 75 days, runs under 38dB with no water or heat, has auto-stop and a key-lock for public spaces, and is CE, RoHS and SGS certified. Made in India.

The three objections developers raise, answered
Three objections come up in almost every procurement conversation about launch scenting. Here they are with the specification against each, including the one that stands.
1
Capacity and runtime
Will one tank and one machine actually carry the event?
The concern is that a launch is an unusually demanding evening and a 400ml tank sounds small. It is not: that fill runs up to about 75 days depending on intensity and run hours, so a four-hour event uses a small fraction of it. The real capacity question is coverage rather than tank size - 1000m³, roughly 2,000 to 3,000 sq ft. Measure the volume of your launch space before anything else, because that number, not the guest count, decides whether this machine is the right one.
Tip: the tank is never the limit at a launch. The volume of the room is.
The Vaayu holds 400ml lasting up to 75 days, so the pre-launch test fill usually carries the event itself.

2
Noise, safety and control
A public crowd, a live microphone and a venue walkthrough
Under 38dB puts it below the air-conditioning noise floor in most halls, and because it is waterless there is no misting or bubbling sound at all, so it does not register against a speech or an AV check. For safety, the key-lock is designed for exactly this situation: engage it and the settings cannot be changed by a guest, a child or an enthusiastic colleague. Auto-stop covers an empty tank. CE, RoHS and SGS certification generally closes the conversation with a venue or a legal team. And the Bluetooth app works from a phone in the room, so venue wifi is irrelevant.
In a much larger hall the Angaan keeps the same discipline at 3,000m³ and under 42dB, with a metal body for permanent installation.

Where the answer is honestly no
A banquet-scale hall, and anything open to the sky
If your launch is in a single volume of 8,000 to 10,000 sq ft, a Vaayu is not the right machine and three of them is a worse answer than one, because scattered sources make a room uneven. That is an Angaan at 3,000m³. The second honest no is open air: a podium deck, a lawn or a porte-cochere cannot hold a fragrance at any intensity, and no machine we sell will change that. Scent the enclosed volumes and leave the open ones alone.
Tip: if the room is banquet scale or open to the sky, we will tell you so before you order.
Within its rating the Vaayu is the right tool; beyond it, we would rather sell you nothing than sell you four of them.

The SOSA principle
A specification is only useful if it also tells you where the machine stops working, and this one stops at about 3,000 sq ft in a single volume.
Every other objection to using a Vaayu at a launch is answered on the spec sheet.
Where the answer is yes, and where it is honestly no
The table below is the suitability answer in four lines, including the two places where we would tell you to buy something else or nothing at all.
The SOSA plan
Suitable, or not, by space
| Your launch space | The honest answer |
|---|---|
|
A launch floor, preview room or foyer up to about 3,000 sq ft
|
Yes. One SOSA Vaayu (₹11,999) at 1000m³, key-locked, on a 4h app timer from 45 minutes before doors. View → |
|
The sales gallery and sample flat afterwards
|
Yes, and this is where the value is - the same machine runs at a lower intensity for the life of the project. View → |
|
A banquet hall or large marquee of 8,000-10,000 sq ft
|
No. That is a SOSA Angaan (₹25,999) at 3,000m³. Several Vaayu units in one hall is worse, not better. View → |
|
An open podium, lawn or porte-cochere
|
No machine at all. Open air cannot hold a fragrance at any intensity, and we would rather say so than sell you one. |
If the answer above turned out to be the Angaan, the counting logic for larger venues is set out in how many scent machines a large property launch event needs, including the marquee height trap. If it is the Vaayu, the practical rigging questions a venue will ask are covered in the best scent machine setup for a project launch. And for the ongoing space the machine works in afterwards, the pillar guide on planning scenting for a luxury real estate sales gallery has the full sizing and schedule.
Suitable up to 1000m³, and we will tell you when it is not
SOSA Vaayu ₹11,999 - 400ml up to 75 days, under 38dB, key-locked, CE, RoHS and SGS certified. Send the hall dimensions and we will tell you which machine you need.
We would rather tell a developer that their hall is too big for our smaller machine than sell them four of it and lose the sales gallery afterwards.

The SOSA suitability specification
One machine is the subject of this page and the other is what we recommend when the room is beyond it. The Vaayu is suitable for launch floors, foyers, galleries and sample flats up to about 3,000 sq ft each; the Angaan is the answer for a single volume of 8,000-10,000 sq ft. Both are waterless, both are made in India, and a portion of every order supports girl-child education through Nanhi Kali.

A quick word on suitability: judge it on the volume of the room rather than the importance of the evening, and treat any recommendation that ignores the cubic metres with suspicion. One honest note - fragrance works alongside ventilation and cleaning, cannot cover fresh paint, adhesive or damp, and SOSA makes no claim that scent influences a purchase decision.

A note from Sonal
I like this question because it is the one a careful procurement team asks, and it usually arrives as a list: how long does the tank last, how loud is it, what stops a guest touching it, is it certified, and is it enough for our hall. Four of those five are answered by the specification. The fifth one is the only one that ever changes my recommendation.
So, plainly: the Vaayu is rated to 1000m³, about 2,000 to 3,000 sq ft. Within that, it is the right machine for a launch - 400ml lasting up to 75 days, under 38dB, waterless so nothing reaches a hired finish, auto-stop, a key-lock built for public spaces, and CE, RoHS and SGS certification. Beyond that, in a banquet hall or a large marquee, it is the wrong machine and buying three of them is worse than buying one Angaan, because scattered sources make a big room uneven and unevenness is what reads as equipment.
And the part I would rather say before the order than after: fragrance will not cover a construction smell and will not sell an apartment. Fresh paint, adhesive and damp need ventilation and time, scent works alongside cleaning rather than instead of it, and we make no claim that fragrance influences a purchase decision. Our hotel-inspired scents are our own original interpretations and SOSA is not affiliated with any hotel. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Is the SOSA Vaayu suitable for a luxury project launch?
Yes for any launch volume up to about 1000 cubic metres, roughly 2,000 to 3,000 sq ft, which covers a launch floor, a foyer, a sales gallery or a sample flat. It is waterless, runs under 38dB, holds 400ml lasting up to about 75 days, has auto-stop and a key-lock for public spaces, and is CE, RoHS and SGS certified. For a single hall of 8,000 to 10,000 sq ft the right machine is the SOSA Angaan at Rs 25,999.
Will a 400ml tank run out during a launch event?
No. A 400ml fill lasts up to about 75 days depending on intensity and run hours, so a four-hour event uses a small fraction of one tank. The fill you put in for pre-launch testing usually carries the event and continues into the sales gallery period afterwards.
Is it audible during speeches or performances?
No. It runs under 38dB, below the air-conditioning noise floor in most halls, and because it is waterless there is no misting, bubbling or hiss. It does not register against a live microphone or an AV system.
Can guests or staff tamper with the settings during the event?
Not with the key-lock engaged. It is designed for public spaces and fixes the intensity and schedule so nobody can alter them mid-event. Auto-stop handles an empty tank, and CE, RoHS and SGS certification is usually what a venue safety walkthrough asks to see.
Does it need venue wifi to run on a schedule?
No. Control is by Bluetooth app from a phone in the room, with onboard buttons as a fallback, and the 1, 4, 8 and 24 hour timers hold their schedule with no network connection at all. Set it during afternoon setup and it runs on its own.
