What should be done before installing a diffuser in a new sample flat? Let the finishes cure and ventilate the flat properly. Fresh paint, adhesive, new PVC and damp cannot be covered by fragrance, and scenting over them gives you both smells at once. Only install the SOSA Vaayu (₹11,999) once the flat smells clean with the machine off.
What is the daily routine for a scented sample flat? Air-conditioning on, bedroom doors open, machine already running 30 to 45 minutes before the first appointment, off at closing. The SOSA Vaayu (₹11,999) handles the running part with its 1h, 4h, 8h and 24h timers, so the only human tasks are the doors and the air-conditioning.

Straight answer
What is the full setup for a SOSA Vaayu in a sample flat?
Five stages, in this order. One: cure and ventilate. A newly finished flat smells of paint, adhesive, new PVC and sometimes damp, and none of that can be covered by fragrance - scent laid over it gives you both smells at once. Open the flat up, run the exhausts, let the finishes cure, and only continue when the flat smells clean with no machine in it. Two: place the machine. One SOSA Vaayu (₹11,999) is rated to 1000m³, about 2,000-3,000 sq ft, which covers a whole flat, so there is one unit and it goes on the entrance-to-living air path, 1.2 to 1.8 metres up, within a few metres of where conditioned air enters the living space. Freestanding on a console, wall mounted at about 1.5 metres or fixed to the HVAC, decided with the interior designer before the flat is dressed. Three: set it soft. Fill the 400ml tank, pair the Bluetooth app, and choose the lowest intensity that registers in the first ten seconds after the front door opens. A sample flat runs below the sales gallery, always, because a home that smells strongly perfumed reads as staged. Judge the level walking in from outside, never from the sofa. Four: schedule and lock. Set a timer - 1h for a single appointment, 4h for a weekday run of viewings, 8h for weekend walk-in hours - starting 30 to 45 minutes before the first buyer, and off at closing. Then engage the key-lock, which is designed for public spaces. Five: hand it over. Give the sales team a two-line routine - air-conditioning on, bedroom doors open, 30 minutes before the first appointment - and log the refill date, because the 400ml tank lasts up to about 75 days depending on intensity and run hours. Auto-stop handles an empty tank, and at under 38dB nobody will hear it. A free scenting plan will write this out for your site team, and a portion of every order supports girl-child education through Nanhi Kali.
Cure and ventilate, place one machine on the air path, set it low, schedule it 30 to 45 minutes ahead, key-lock it, log the refill. In that order.
The whole setup is one SOSA Vaayu - rated to 1000m³, about 2,000-3,000 sq ft, waterless, under 38dB, with a 400ml tank lasting up to 75 days, 1h/4h/8h/24h app timers, adjustable intensity, auto-stop and a key-lock for a flat full of visitors.

Ventilate, place, set, schedule, lock - and nothing before the flat has cured
The one machine this guide sets up
One machine to install, and a short routine to hand over. The pictures link to the product page for dimensions, power and certifications.
The one unit the flat needs
SOSA Vaayu
Rated to 1000m³ - about 2,000-3,000 sq ft - so one machine covers the whole flat. Waterless, under 38dB, 400ml tank lasting up to 75 days, Bluetooth app with 1h/4h/8h/24h timers, adjustable intensity, auto-stop and key-lock.
From ₹11,999
Installed without giving up a styled surface
SOSA Vaayu, wall mounted
165 x 80.5 x 215mm and 0.9kg, so it stands on a console, wall mounts at about 1.5 metres or fixes to the HVAC. Agree the mounting point before the flat is dressed and the install takes ten minutes.
From ₹11,999
Handed over to the sales team
SOSA Vaayu, scheduled and locked
Set the intensity and timer once, engage the key-lock, and the flat smells the same for every appointment of the launch. Auto-stop covers an empty tank, and one 400ml fill usually lasts a quarter.
From ₹11,999
The three stages of a sample flat installation
The installation splits into three stages: what happens before the machine arrives, install day itself, and the routine you hand to the sales team.
1
Before the machine: cure and ventilate
The stage people skip, and the one that cannot be fixed later
A flat that has just been finished is still off-gassing paint, adhesive, sealant and new PVC, and if there has been water ingress during fit-out it may be holding damp as well. Fragrance cannot cover any of that. Open the flat, run the exhausts, keep the air-conditioning circulating, and give the finishes their curing time. The test is simple and unforgiving: with no machine in the flat, does it smell clean? If not, the installation waits.
Tip: if the flat still smells of paint, no setting on any machine will help. Ventilate for longer.
2
Install day: place, fill, set, lock
About half an hour of work, done once
Mount the unit on the entrance-to-living air path at 1.2 to 1.8 metres - console, wall at about 1.5 metres, or the HVAC. Fill the 400ml tank. Pair the Bluetooth app, set the lowest intensity that registers when the front door opens, and pick the timer that matches your viewing pattern with a 30 to 45 minute head start. Walk out for twenty minutes and judge the level coming back through the door. Adjust once if you must, then engage the key-lock so the setting survives the launch.
Freestanding, wall or HVAC mount on a 0.9kg unit, with app control and a key-lock for public spaces.

3
The routine you hand over
Two tasks each morning and one refill a quarter
The sales team gets two jobs: switch the air-conditioning on and open the bedroom doors, both at least 30 minutes before the first appointment. The machine handles itself on the timer. Put the refill date in the site diary rather than trusting memory - the 400ml tank runs up to about 75 days depending on intensity and run hours, and auto-stop will halt the unit if it empties first. If the flat closes between launches, switch the machine off and run it briefly once a week.
Tip: write the two-line routine on a card and leave it in the sales desk drawer.
1h/4h/8h/24h timers, auto-stop and a 400ml tank lasting up to 75 days keep the day-to-day work close to zero.

The SOSA principle
Every failed show flat installation we are called to fix is a sequencing problem: the machine went in before the flat had finished curing, and the setting was raised to compensate.
Ventilate, then place, then set. The order is the method.
The setup, stage by stage
Here is the setup as a table, stage by stage, so it can be handed to a site team directly.

Handover: the daily routine
|
Air-conditioning on and bedroom doors open 30 minutes ahead. The timer starts the machine, the key-lock protects the setting, the diary carries the refill date. View → |
Order one fragrance for every machine on the project, including the sales gallery, and differentiate the spaces with intensity rather than scent - a clean profile such as white tea, light woods or soft citrus survives a full day of air-conditioned viewings. The two pages that go deeper on the stages here are where to place a scent machine in a sample flat and how long before buyer visits the machine should run. If you are still deciding the count for a larger unit, how many machines a 4BHK sample flat needs covers duplexes, and the sales gallery scenting plan covers the site as a whole.

A quick word on choosing: the sequence is the product here. Cure and ventilate, place one machine well, set it softer than the sales gallery, schedule it, lock it. One honest note - fragrance works alongside ventilation and cleaning, never instead of them, and cannot cover fresh paint, adhesive, new PVC or damp. A free scenting plan will write the whole setup out for your site team.

A note from Sonal
Most of the show flats I am asked to rescue were set up in the wrong order. The machine arrived on the same day as the styling, went in while the paint was still curing, and got turned up over the following fortnight because the flat did not smell right. By the launch it smelled of two things at once.
So this guide is really about sequence. Ventilate and cure first. Then place one Vaayu on the entrance-to-living air path, because a machine rated to 1000m³ covers a whole flat and there is nothing to gain from a second one unless a duplex level is closed off. Then set it soft, schedule it 30 to 45 minutes ahead of viewings, lock it, and write the refill date in the diary.
The honest note I put in every specification: fragrance works alongside ventilation and cleaning, never instead of them, and it cannot cover fresh paint, adhesive, new PVC or damp. A sample flat should also run softer than the sales gallery, because a home that smells strongly perfumed reads as staged. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How do you set up a SOSA Vaayu in a sample flat?
Cure and ventilate the flat first, then place one machine on the entrance-to-living air path 1.2 to 1.8 metres up, fill the 400ml tank, pair the Bluetooth app, set a low intensity, schedule a timer to start 30 to 45 minutes before viewings, engage the key-lock and log the refill date. One unit at Rs 11,999 covers a whole flat.
What has to happen before the machine goes in?
The finishes need to cure and the flat needs proper ventilation. Fresh paint, adhesive, new PVC and damp cannot be covered by fragrance, and scenting over them gives you both smells at once. The test is whether the flat smells clean with no machine running.
What is the daily routine for the sales team?
Two things: switch the air-conditioning on and open the bedroom doors, both at least 30 minutes before the first appointment. The timer starts the machine on its own, and the key-lock keeps the setting where you left it.
How often does it need refilling?
The 400ml tank lasts up to about 75 days depending on intensity and run hours, so at show flat settings one fill usually covers a launch quarter. Put the date in the site diary. Auto-stop halts the unit if the tank empties first.
Do we need a second machine anywhere?
Only in a duplex whose upper level is closed off by a door or runs on its own air-conditioning. On a single level, even a 2,000 to 3,000 sq ft flat sits inside one machine's 1000 cubic metre rating, so a second unit adds intensity rather than coverage.
Ventilate, place, set, schedule, lock - in that order
