Should the machine run continuously or only before appointments? On a busy day, run it continuously at a low intensity rather than in strong bursts before each slot. It uses less oil, avoids a wave of fragrance arriving with each buyer, and reads far better. The SOSA Vaayu's 4h and 8h timers (₹11,999) cover a typical viewing window in one setting.
Should the scent machine run overnight in a show flat? No, switch it off at closing. There is nobody to smell it, and an empty flat that has been scented for twelve hours smells heavier in the morning, not fresher. Use the SOSA Vaayu's timers (₹11,999) to start again 30 to 45 minutes before the first appointment.

Thirty to forty-five minutes. Long enough for the fragrance to diffuse and settle, short enough that you are not scenting an empty flat all morning. Here is how that maps onto the Vaayu's four timers for appointment days, weekends and quiet weeks.

Thirty to forty-five minutes of lead time is what turns a scented room into a home that simply smells this way. The four app timers exist so the sales team never has to think about it again.

Straight answer
How long before a buyer arrives should the sample flat scent machine be switched on?
Thirty to forty-five minutes. Fragrance released into a room needs time to disperse through the flat's air and settle to a steady level, and that settling is the difference between a home that smells this way and a room where something was switched on. Scent that arrives at full strength as a family walks through the door is noticeable, and noticeable is the opposite of what you are trying to achieve. The SOSA Vaayu (₹11,999) has a Bluetooth app with 1h, 4h, 8h and 24h timers and adjustable intensity, which covers every real viewing pattern. For a single appointment at 11am, start at 10:15 on a 1h timer. For back-to-back weekday viewings from 11am to 3pm, use the 4h timer from 10:30 and let it run through - do not switch it on and off between buyers. For weekend walk-in hours of 10am to 7pm, an 8h run at a low intensity from 9:15 covers the day in one setting. The principle underneath all of that: on a busy day, a low continuous run beats strong bursts. Bursts produce a wave of fragrance that a buyer walks into, they use more oil, and they leave the flat uneven between slots. Continuous low is steadier, cheaper and better. Switch off at closing, because an empty flat scented overnight smells heavier the next morning rather than fresher, and there is nobody there to appreciate it. Between launches, when the flat is closed, leave the machine off and run it briefly once a week so the flat does not develop the shut-up smell instead. The 400ml tank lasts up to 75 days depending on intensity and run hours, so a sensible schedule usually carries an entire launch quarter on one fill. And the one thing an early start cannot do: cover fresh paint, adhesive, new PVC or damp. Cure and ventilate first. A free scenting plan will map your viewing hours to the timers, and a portion of every order supports girl-child education through Nanhi Kali.
Start 30 to 45 minutes before the first buyer, run low and continuous through the viewing window, and switch off at closing.
The schedule lives on the SOSA Vaayu - a Bluetooth app with 1h, 4h, 8h and 24h timers plus adjustable intensity, a 400ml tank lasting up to 75 days, and a key-lock so the sales team cannot override it on a busy Saturday.

So nobody has to remember it
SOSA Vaayu, key-locked
Set the schedule once and lock the unit. The flat then smells the same for the 11am appointment and the 6pm one, without a sales executive deciding to give it a boost before an important buyer arrives.

Building the run schedule around your viewing calendar
Three questions build the schedule: why 30 to 45 minutes, what to do on a busy day, and when the machine should be off.
1
Why 30 to 45 minutes
Diffusion takes time, and settled fragrance reads as belonging
Nebulised fragrance has to travel from the machine through the living space, down the corridor and into rooms whose doors you have just opened. Half an hour of that produces an even, settled presence. Five minutes produces a strong plume near the machine and nothing at the far end. The same window is also when your sales team should be opening bedroom doors and switching the air-conditioning on, so it is one routine rather than three.
Tip: put the machine on the same timer as the air-conditioning and the door-opening round.
The Vaayu app runs 1h, 4h, 8h and 24h schedules, so a 45 minute head start is set once and repeats.

2
On a busy day, run low and continuous
Bursts before each appointment are worse and cost more
The instinct on a heavy viewing day is to give the flat a strong burst before each slot. It backfires: each buyer walks into a wave, the flat swings between too much and too little, and you spend noticeably more oil. A low intensity running continuously through the viewing window is steadier for every visitor, cheaper across the quarter, and requires no decisions from anyone. Use the 4h timer for a weekday run of appointments and the 8h for weekend walk-in hours.
A 400ml tank lasting up to 75 days makes continuous low running the economical choice as well as the better one.

Know when to switch it off
Closing time, and between launches
Switch off at closing. There is nobody in the flat, and an apartment scented through the night smells heavier in the morning, not fresher. Between launches, when the show flat is shut for weeks, leave the machine off entirely and run it for an hour once a week with the windows opened afterwards, which keeps the flat from developing a closed-up smell. Auto-stop protects the unit if the tank runs dry while you are away.
Tip: the machine should be off more hours of the week than it is on.
Auto-stop and the key-lock mean an unattended flat looks after itself between visits.

The SOSA principle
A buyer can tell the difference between a home that smells this way and a room that was switched on. The difference is about forty minutes.
Schedule it against the viewing calendar, not against office hours.
Timer settings for each kind of viewing day
Here is the schedule for each kind of day, mapped to the four timer settings.

Timing and intensity are two halves of one decision: a machine that starts late gets turned up to compensate, and then the flat is too strong for everyone who arrives afterwards. Set the level first, using how strong fragrance should be inside a sample apartment, then build the schedule around it. If you are setting the flat up from scratch, the SOSA Vaayu sample flat placement and setup guide puts the whole sequence in order, and the sales gallery scenting plan covers scheduling the gallery alongside the flat.

A quick word on choosing: the timer is what makes this work in a real sales operation, because it removes the decision from a team that is busy with buyers. One honest note - an early start cannot fix a newly finished flat. Fragrance works alongside ventilation and cleaning and cannot cover fresh paint, adhesive, new PVC or damp. A free scenting plan will map your viewing hours onto the four settings.

A note from Sonal
The commonest failure in a show flat is not the wrong fragrance or the wrong machine. It is a sales executive switching the machine on as the lift doors open, because the appointment came in late and nobody planned for it. The buyer walks into a plume, and the whole thing announces itself.
Thirty to forty-five minutes is all it takes for that plume to become an atmosphere. The Vaayu has 1h, 4h, 8h and 24h timers in the app precisely so this stops being a person's job. One appointment gets a 1h run. A weekday of viewings gets 4h. A weekend of walk-ins gets 8h on a low setting. Closing time gets nothing at all.
The honest caveat that no schedule fixes: fragrance cannot cover fresh paint, adhesive, new PVC or damp in a newly finished flat, and starting the machine earlier will not change that. Cure the finishes, ventilate properly, clean the flat, and then let a gentle, well-timed run do the quiet work - alongside the ventilation, never instead of it. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How long before buyer visits should a sample flat scent machine run?
Thirty to forty-five minutes. That gives the fragrance time to diffuse through the flat and settle, so it reads as the smell of the home rather than something just switched on. The SOSA Vaayu (Rs 11,999) has 1, 4, 8 and 24 hour timers in its Bluetooth app for exactly this.
Should it run continuously through a busy viewing day?
Yes, at a low intensity. Continuous low running is steadier for every visitor and uses less oil than strong bursts before each appointment, which produce a wave of fragrance and leave the flat uneven between slots. Use the 4 hour timer for a weekday run and the 8 hour for weekend walk-in hours.
Should the machine run overnight?
No, switch it off at closing. There is nobody there to smell it and an empty flat scented all night smells heavier in the morning rather than fresher. Restart 30 to 45 minutes before the first appointment the next day.
What should we do when the show flat is closed between launches?
Leave the machine off and run it for about an hour once a week, ventilating afterwards, so the flat does not develop a closed-up smell. Auto-stop protects the unit if the tank empties while nobody is there.
How long does a tank last on this schedule?
The 400ml tank is rated to last up to about 75 days depending on intensity and run hours, so a low continuous run through normal viewing hours will usually carry a whole launch quarter on one fill.
