What makes several sites actually smell the same? Identical settings, not identical machines. Two SOSA Vaayu units running at different intensity steps and different timer blocks will smell like two different buildings. Write the intensity step and the schedule (1h, 4h, 8h or 24h) into a one-page settings sheet, set every machine to it, then use the key-lock so nobody adjusts it on a quiet afternoon.
How much fragrance oil does a multi-site developer need per quarter? Do the arithmetic from the tank. A 400ml SOSA Vaayu tank lasting about 75 days is roughly 5.3ml a day, so about 480ml per machine over a 90-day quarter. Twelve machines across six sites is about 5.8 litres a quarter at moderate intensity. Run harder or longer and a tank can empty in 45 days instead, which pushes the same twelve machines towards 9.6 litres, so order against the top of that band and hold a buffer.

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, freestanding or wall and HVAC mounting, auto-stop and key-lock for public spaces, and CE, RoHS and SGS certification. 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, connecting to the building's HVAC or running standalone wall-mounted or lay-flat. 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.
If you run scenting at one site it is a purchase. If you run it at six it is a programme, and programmes fail on paperwork rather than on hardware. Here is the whole thing: a site register, one specification, one settings sheet, one fragrance decision and a refill round that fits on a calendar.
Quick answers — read this first
How do I plan scenting across multiple real estate project sites? Treat it as an operations job with four parts. First, a site register: for every site, the air volume of each connected space, so you know the machine count. One SOSA Vaayu (₹11,999) covers 1000m³, about 2,000-3,000 sq ft, so a typical site is one machine in the sales office and one in the sample flat. Second, one specification, so every site buys the same machine. Third, one fragrance and one settings sheet, so intensity and timers match. Fourth, a monthly top-up round, because a 400ml tank lasts up to about 75 days depending on intensity and run hours.What makes several sites actually smell the same? Identical settings, not identical machines. Two SOSA Vaayu units running at different intensity steps and different timer blocks will smell like two different buildings. Write the intensity step and the schedule (1h, 4h, 8h or 24h) into a one-page settings sheet, set every machine to it, then use the key-lock so nobody adjusts it on a quiet afternoon.

Run harder or longer and a tank can empty in 45 days instead, which pushes the same twelve machines towards 9.6 litres, so order against the top of that band and hold a buffer.
The short answer
Short answer: build a site register first, then fix one specification for the whole portfolio - one SOSA Vaayu (₹11,999) per 1000m³, which is about 2,000-3,000 sq ft, usually one in the sales office and one in the sample flat - then one fragrance, one settings sheet and one monthly refill round; step up to the SOSA Angaan (₹25,999) only where a single volume is double height or 8,000-10,000 sq ft.
The pick: the SOSA Vaayu (₹11,999) as the standard unit at every site, with the SOSA Angaan (₹25,999) reserved for the one or two volumes that are genuinely too tall or too large for it.
Next step: send the site list with approximate areas and ceiling heights and we will build the register with you - book a free multi-site scenting plan.

A multi-site plan is four ordinary documents and one recurring calendar entry. The machines are the easy part - the register, the settings sheet and the refill log are what make six sites smell alike.

Straight answer
How do I plan the scenting across all of my live project sites at once?
Start with a register, not with a quote. List every live site, and under each site list the connected air volumes - sales office, lounge, sample flat, experience centre - with length, width and height in metres. One SOSA Vaayu (₹11,999) is rated to 1000m³, roughly 2,000-3,000 sq ft at a normal ceiling, so most sites resolve to two machines: one for the sales office and one for the sample flat. Only where a single volume is double height or runs to 8,000-10,000 sq ft do you step up to an SOSA Angaan (₹25,999) on the HVAC. Second, write the specification once so every site buys the same machine - identical hardware is what makes settings transferable. Third, decide the fragrance at portfolio level, not at site level, and write one settings sheet: the same intensity step and the same timer block (1h, 4h, 8h or 24h) on every unit, then engage the key-lock so it stays that way. Fourth, put the refill round on the calendar. A 400ml tank lasts up to about 75 days depending on intensity and daily run hours, which is roughly 5.3ml a day, so a site with two machines uses close to a litre a quarter and a twelve-machine portfolio lands between about 5.8 and 9.6 litres a quarter depending on how hard you run. One honest caveat that applies at every site: cure and ventilate fresh paint and adhesive before scenting anything. A free multi-site scenting plan will do the register with you, and a portion of every order supports girl-child education through Nanhi Kali.
Register, specification, settings sheet, refill calendar. One SOSA Vaayu per 1000m³, one fragrance across the portfolio, one monthly top-up round.
The standard unit for a developer portfolio is the SOSA Vaayu - waterless, under 38dB, rated to 1000m³ (about 2,000-3,000 sq ft), with a 400ml tank that runs up to about 75 days, adjustable intensity, 1h/4h/8h/24h timers and a key-lock so site staff cannot quietly change the settings you standardised.

The portfolio shortlist
Two machines cover every site you own. The register decides which goes where.
The two machines a developer portfolio uses
A developer specification has two machines in it, and the only question is air volume. Buying the same unit at every site is not laziness - it is what lets one settings sheet, one fragrance order and one spare part cover the whole portfolio.
The standard site unit - sales office, lounge, reception
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft. 400ml tank lasting up to about 75 days, Bluetooth app and onboard buttons, 1h/4h/8h/24h timers, adjustable intensity, under 38dB, key-lock for public spaces.
From ₹11,999
The second unit at the same site - the sample flat
SOSA Vaayu (second unit)
Every site that has a show apartment needs its own machine there, running the same fragrance one intensity step softer than the sales office. Freestanding or wall mounted, no water and no residue on finishes.

The exception - a double-height or 8,000-10,000 sq ft volume
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, 800ml reservoir, metal body, programmable schedules, under 42dB. Most portfolios need one of these, at the flagship experience centre, and Vaayu everywhere else.

The three documents that make a multi-site plan work
A multi-site programme runs on three documents. Each one takes under an hour to write and saves a quarter of arguing later.
1
The site register
One row per connected volume, across every live project
For each site, list the spaces that share moving air and give each one length, width and height in metres. Multiply, divide by 1000, and you have the Vaayu count for that volume. Almost every sales office lands at one. Almost every sample flat lands at one, whatever the number of bedrooms, because a flat is a single connected volume and not six rooms. The register is also where you record ceiling height, because that is the number floor-area rules of thumb quietly ignore and the reason two sites of the same square footage can need different answers.
Tip: keep the register in one sheet with a row per volume, not a file per site.
The Vaayu is rated to 1000m³, about 2,000-3,000 sq ft. That single number turns the register into a machine count.
See SOSA Vaayu →
2
The specification
Same machine, same fragrance, same settings, every site
Write one page: the machine, the fragrance, the intensity step, the timer block and the mounting position. Buy the same unit everywhere, because identical hardware is what makes the settings sheet portable - a step that means one thing on one machine and something else on another is not a standard. Fix the fragrance at portfolio level too. Deciding it site by site is how a developer ends up with four fragrances, four minimum stock levels and a bottle in the wrong machine.
Where a single volume is double height or 8,000-10,000 sq ft, the Angaan is the specified exception - one machine on the HVAC rather than four small ones fighting each other.
See SOSA Angaan →
3
The refill calendar
One round a month, one order a quarter
A 400ml tank lasts up to about 75 days, and that figure moves with intensity and daily run hours. Rather than guess, top every machine up on the same day each month and write down the millilitres you added. After two rounds the log tells you the true consumption per site, and the quarterly order stops being an estimate. Budget roughly 480ml per machine per quarter at moderate settings, and closer to 800ml where a site runs hard and long.
Tip: log the millilitres you add, not the date you visited - the numbers are what you order from.
The Vaayu tank is 400ml and refillable, so a monthly round is a top-up and a note, not a swap.
See SOSA Vaayu →
The SOSA principle
Six sites do not smell alike because you bought six identical machines. They smell alike because someone wrote down the intensity step and the timer, and then locked them.
The hardware is a one-day decision. The documents are what you live with for three years.
What each site type needs, in one table
Here is the whole portfolio in one table. Almost every row is a Vaayu, which is the point: a developer specification should be boring and repeatable, with exactly one documented exception for the volume that is genuinely too big.

On the fragrance itself, decide it once for the whole portfolio and treat it as a brand asset rather than a site preference. That decision deserves a proper look, so we have written it up separately in one signature scent versus a different fragrance for each project, and the practical consequences land in managing fragrance inventory across multiple sales offices. Air-conditioned sales offices flatten sweetness and amplify anything heavy, which is why restrained profiles - white tea, light woods, soft citrus - hold up through a full day of viewings while dessert-like ones turn cloying by the third appointment. If you are starting from a single flagship rather than a portfolio, the sales gallery scenting plan is the better first read.
One specification, repeated across every site you own
SOSA Vaayu ₹11,999 covers up to 1000m³ - about 2,000-3,000 sq ft. Send the site list and we will build the register and the machine count with you.
A portfolio that smells consistent is not a fragrance achievement. It is an operations one, and it fits on two sides of paper.

Why the same machine everywhere
Identical hardware is what makes a settings sheet portable between sites
The SOSA multi-site specification
Two machines, one decision rule. The Vaayu is the repeating unit at every site; the Angaan is the documented exception for a volume that is genuinely too tall or too large. Both are waterless, so there is no damp and no residue on scale models, veneers or fabric, and both are made in India. A portion of every order supports girl-child education through Nanhi Kali.

A quick word on choosing: the count comes from air volume, not from site count or budget. Twelve small machines scattered across a site smell like twelve rooms; two machines sized to the connected air smell like one building, and that repeats cleanly across six sites. One honest note - fragrance works alongside curing, ventilation and cleaning during fit-out and cannot cover fresh paint, adhesive or damp. The quickest way to get the register right is a free multi-site scenting plan.

A note from Sonal
Developers rarely have a scenting problem. They have a consistency problem. Each site buys something, each site sets it to whatever felt right that week, and eighteen months later the flagship smells expensive, the second project smells of nothing and the third smells like an airport washroom. The buyer who visits two of your projects in one weekend notices, even if they never say so.
What I recommend is dull on purpose. One machine type, so a settings sheet written once is valid everywhere - the Vaayu is rated to 1000m³, which covers a normal sales office or a sample flat on its own. One fragrance across the portfolio. One intensity step, one timer block, key-locked. The only exception I ever write into a developer specification is the Angaan at the one experience centre that is genuinely double height, because stacking small machines into a tall volume never works.
And the honest part, which I say to every developer before they sign anything: scent does not sell a flat. I make no claim that fragrance influences a purchase decision, and anyone who tells you otherwise is selling harder than I am. What it does is hold the perceived quality of the experience steady across six sites, so your second project feels as considered as your flagship. It also works alongside ventilation and cleaning, never instead of them, and it cannot cover fresh paint or adhesive. SOSA is an independent Indian brand, not affiliated with any hotel, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How do I plan scenting across several real estate project sites?
Build a site register first: every connected volume at every live site, with length, width and height in metres. One SOSA Vaayu (Rs 11,999) covers 1000 cubic metres, about 2,000 to 3,000 sq ft, so most sites resolve to two machines, one in the sales office and one in the sample flat. Then write one specification, one settings sheet and one refill calendar for the whole portfolio. A double-height or 8,000 to 10,000 sq ft experience centre is a SOSA Angaan (Rs 25,999) on the HVAC instead.
Should every project site use the same machine?
Yes, wherever the air volume allows it. Identical hardware is what makes a settings sheet portable: the same intensity step and the same timer block mean the same thing on every unit, spares are interchangeable, and a new site can be commissioned from a one-page document. Keep exactly one documented exception for a volume that is genuinely too tall or too large for a Vaayu.
How much fragrance oil will a six-site portfolio use in a quarter?
Work it out from the tank rather than guessing. A 400ml SOSA Vaayu tank lasting up to about 75 days is roughly 5.3ml a day, so about 480ml per machine over a 90-day quarter. Six sites with two machines each is twelve machines, which is about 5.8 litres a quarter at moderate intensity. If sites run at higher intensity or longer hours a tank can empty in about 45 days instead, which takes the same twelve machines to around 9.6 litres, so order towards the top of that band.
Does the sample flat need a different fragrance from the sales office?
No. Same fragrance, one intensity step softer in the flat. A show apartment that smells strongly perfumed reads as staged; the same scent, quieter, reads as lived in. Using a different fragrance in the flat also doubles your stock lines for no gain.
Will fragrance help sell more flats at a site?
We make no such claim. Scent supports the perceived quality and consistency of the experience across your sites, and nothing more than that. It also works alongside ventilation and cleaning rather than instead of them, and it cannot cover fresh paint, adhesive or damp, all of which need curing and airing first.
