Does a scent machine use fragrance continuously? No. It releases fragrance in controlled bursts on a timer - 1h, 4h, 8h or 24h - and you set the intensity from the app, so you decide how much it uses. A higher intensity and longer daily hours use more; a gentler setting makes a tank last longer, up to about 75 days.
How much fragrance does a whole multi-storey home use? Multiply by floors. Each Vaayu on each floor draws from its own 400ml tank that lasts up to about 75 days, so a three-floor bungalow with three machines uses roughly three tanks over the same period - one per floor, since scent does not climb a staircase.
Shop Vaayu ₹11,999
Facts verified August 2026 (SOSA Vaayu product page): The Vaayu is a waterless cold-air diffuser priced at ₹11,999, and each machine ships with four SOSA Hotel Collection fragrance oils of 100ml each (400ml total, about one full tank). It atomises alcohol-free, water-free fragrance oil into a dry nano-mist covering up to 1000m3 (about 2000 to 3000 sq ft), with a 400ml tank that lasts up to about 75 days depending on the intensity setting and daily run hours, 1h/4h/8h/24h timers, Bluetooth app control and under-38dB operation. Fragrance is sized to the volume of air, not just the floor area, so a very large or double-height floor may need the larger Angaan (₹25,999, ~8,000-10,000 sq ft) or Meenar (₹38,500, ~12,000-18,000 sq ft), and a multi-storey bungalow generally needs one machine per floor - scent does not travel up a staircase between floors on its own. A signature scent enhances a clean, well-ventilated home and works alongside good ventilation; it does not remove a musty or closed-up smell, and in a newly built or newly renovated home it is not a substitute for airing out paint, polish and construction fumes, which should be ventilated and allowed to off-gas before a signature scent is introduced. SOSA makes no medical or air-purification claims. The hotel-inspired scents are SOSA's own original interpretations; SOSA is independent and not affiliated with, or endorsed by, any hotel named for reference. Prices and availability are subject to change - see the live product pages.
The question behind this one is usually a worry - will a machine drink fragrance? - and the honest answer is reassuring: a single tank lasts up to about 75 days, so use is occasional, not constant.
Quick answers — read this first
How much fragrance does a whole-home scent machine use? Less than most people expect. A SOSA Vaayu holds a 400ml tank that lasts up to about 75 days depending on the intensity setting and daily run hours, so a tank is roughly a 2 to 2.5 month cycle at typical settings. The exact use depends on your settings, and the machine ships with four oils (400ml in total) so the first tank is included. A multi-storey home runs one machine per floor, so total use scales with the number of machines. Made in India.Does a scent machine use fragrance continuously? No. It releases fragrance in controlled bursts on a timer - 1h, 4h, 8h or 24h - and you set the intensity from the app, so you decide how much it uses. A higher intensity and longer daily hours use more; a gentler setting makes a tank last longer, up to about 75 days.
How much fragrance does a whole multi-storey home use? Multiply by floors. Each Vaayu on each floor draws from its own 400ml tank that lasts up to about 75 days, so a three-floor bungalow with three machines uses roughly three tanks over the same period - one per floor, since scent does not climb a staircase.
The short answer
Short answer: a SOSA Vaayu 400ml tank lasts up to about 75 days by intensity and hours, so fragrance use is occasional (roughly a 2 to 2.5 month cycle) - the machine ships with four oils, and a multi-storey home scales use by one machine per floor.
The pick: one SOSA Vaayu (₹11,999) for an open floor up to ~2000-3000 sq ft (1000m3), with a hotel-inspired signature scent; one per floor of a bungalow, and the Angaan (₹25,999) for a very large or double-height floor.
Next step: shop the SOSA Vaayu, or book a quick consultation to size a large or multi-storey home.
In this guide
Scenting a large independent home well is two decisions: one signature fragrance, and a machine sized to the space. A single SOSA Vaayu cold-air diffuser fills an open floor of up to about 1000m3 (roughly 2000-3000 sq ft) with a clean, hotel-inspired scent, on a timer. A multi-storey bungalow is simply one machine per floor - fragrance is about the volume of air, and it does not travel up a staircase on its own - and a very large or double-height floor may step up to the larger Angaan. In a newly built home, air out the construction and paint smell first, then let the signature scent do the beautiful part. When in doubt, a quick consultation sizes it for you.

Straight answer
Will a scent machine use up a lot of fragrance?
No - use is occasional, not constant. A SOSA Vaayu holds a 400ml tank that lasts up to about 75 days depending on your intensity setting and daily run hours, so a tank is roughly a 2 to 2.5 month cycle at typical settings. It releases fragrance in controlled bursts on a timer (1h/4h/8h/24h) and you set the strength from the app, so you decide how much it uses - a gentler setting simply makes a tank last longer. The machine ships with four hotel-inspired oils (400ml in total), so the first tank is included. For a multi-storey home, total use scales with the number of machines - one per floor - because scent does not climb a staircase. A quick consultation estimates the rhythm for your home.

For most homes the answer is one SOSA Vaayu - a waterless cold-air diffuser that carries a clean, hotel-inspired signature scent across an open floor of up to about 2000-3000 sq ft, on a timer, from one discreet machine. A multi-storey bungalow is one per floor, and a very large or double-height floor is sized up to the larger Angaan. It ships with four hotel-inspired oils, so you can find your signature from day one.

How fragrance use actually works
Fragrance use worries people because they imagine a machine spraying constantly. It does not - it works in controlled bursts you set, so use is modest and, importantly, in your control. Here is how it actually works.
1
A tank lasts up to ~75 days
Occasional, not constant
A 400ml tank in the Vaayu lasts up to about 75 days depending on intensity and daily hours. That makes fragrance a roughly 2 to 2.5 month cycle at typical settings - occasional refills rather than a constant drain.
Tip: a single 400ml tank is a 2 to 2.5 month cycle at typical settings.
2
You set the intensity
Bursts on a timer, not a fog
The machine releases fragrance in short controlled bursts on a 1h, 4h, 8h or 24h timer, and you set the strength from the app. A gentler setting and shorter hours use less and make a tank last longer; a stronger setting uses more.
3
Scale by machines, not by house
One tank per floor
A multi-storey home runs one machine per floor, so total fragrance use is the number of machines times a 400ml tank per cycle. It does not multiply by rooms - each open floor is one machine drawing from one tank.
Tip: total use is one 400ml tank per machine, per floor, per cycle.
The SOSA principle
The fear is always that a machine will guzzle expensive oil. In practice a tank lasting up to about 75 days means most owners refill a few times a year and rarely think about it.
Because you set the intensity, you are the one deciding how much it uses - there is no hidden appetite, just a setting you control.
Estimating use for your home
The clearest way to estimate use is per tank, then per floor. Here is the honest picture - remember the exact figure depends on your settings.
The SOSA scent edit
How fragrance use works (illustrative)
| Scent | Why it suits the mood |
|---|---|
| One open floor, typical settings | One 400ml tank lasting up to about 75 days - roughly a 2 to 2.5 month refill cycle. The first tank ships with the machine. |
| Higher intensity or longer hours | A tank empties faster than 75 days - use scales with how strong and how long you run it, which you control from the app. |
| A multi-storey home | One machine and one tank per floor - total use is the number of machines times a 400ml tank per cycle, since scent does not climb a staircase. |
These are honest estimates, not fixed figures - real use depends on your intensity and daily hours, so treat the up-to-75-day tank as the anchor and adjust to how you like it. The machine ships with four oils (400ml in total), so you start with a full tank included, and refill oils start at Rs 299. A very large or double-height floor running the Angaan (₹25,999) draws from a larger reservoir for its bigger volume of air. A quick consultation estimates the exact rhythm for your floors and settings.
The invisible finishing touch
One SOSA Vaayu gives a large home a clean, five-star signature scent across the whole open floor - ₹11,999, app & timer, ships with four hotel-inspired oils. One per floor for a multi-storey bungalow.
There is no hidden appetite - because you set the intensity, you decide how much fragrance the machine uses, and a tank lasting up to about 75 days means you barely think about it.

The SOSA home edit
Whichever you choose, every SOSA machine here is made in India and sized to a real volume of air. One signature scent across the whole home, a Vaayu for an open floor up to ~2000-3000 sq ft (one per floor of a bungalow), and the Angaan or Meenar for a very large or double-height floor. A scent works alongside good ventilation, and the simplest way to size a large or multi-storey home is a quick consultation. Here is the full edit.
The SOSA independent-home scenting edit
One signature scent, the right machine for your space - a Vaayu per floor of a bungalow, more for a very large or double-height floor
| Machine | Best for | Why it works | From |
|---|---|---|---|
 SOSA Vaayu
|
One open floor up to ~2000-3000 sq ft (1000m3), or one per floor of a bungalow | Waterless cold-air machine with app & timer - one machine for the whole open floor | ₹11,999 |
 Hotel Collection oil
|
The signature scent itself (for the Vaayu) | Hotel-inspired, water-based oils - a clean, five-star signature; the Vaayu ships with four | ₹299 |
 SOSA Angaan
|
A very large or double-height floor | HVAC nebulising diffuser for a very large volume of air | ₹25,999 |
 SOSA Sukoon
|
A single closed bedroom, study or pooja room | Ultrasonic cool-mist diffuser for one small room off the main floor | ₹1,899 |
 SOSA Meenar
|
A very large multi-floor residence (12,000-18,000 sq ft) | Commercial HVAC scenting for the biggest homes | ₹38,500 |
How to size it: fragrance is about the volume of air, not just floor area. One Vaayu fills an open floor of up to about 1000m3 (roughly 2000-3000 sq ft). A multi-storey bungalow is one machine per floor - scent does not climb a staircase on its own. A very large or double-height floor holds far more air than its footprint suggests, so place the machine well and consider the Angaan for a big open volume. Closed bedrooms or a pooja room off the main floor can take a compact Sukoon. Keep one signature fragrance throughout, and if you are unsure, a quick consultation sizes it. Two honest notes: a scent makes a beautiful, well-aired home feel five-star but works alongside good ventilation and does not mask a musty smell; and in a newly built home, let the construction and paint smell air out first, then add the signature scent.

A note from Sonal
Most people spend years building an independent home - the plot, the plan, the interiors, every material chosen with care - and then leave the one sense that triggers memory most strongly entirely to chance. Scent is the finishing touch that makes a home feel as considered as it looks. Done well, your house greets you and your guests with a clean, quietly luxurious signature the moment the front door opens.
The mistake I see is scattering reed diffusers in every room, which clutters beautiful interiors and still leaves the house smelling uneven. A single Vaayu cold-air diffuser does the opposite: one signature scent, carried evenly across an open floor of up to about 2000-3000 sq ft, from one discreet machine on a timer. It is the invisible finishing touch on a dream home.
Two honest rules I always give. First, size it to the space: a multi-storey bungalow is one machine per floor, and a very large or double-height floor holds more air than its footprint suggests, so it is a bigger machine, not one working too hard - scent does not climb a staircase on its own. Second, if the home is newly built, let the paint and construction smell air out fully first; a scent enhances a clean, well-aired home, it is a luxury, not a cover-up. Everything is made in India, and for a large or multi-storey home a quick consultation gets the sizing exactly right.
Frequently asked questions
How much fragrance does a whole-home scent machine use?
Less than most people expect. A SOSA Vaayu holds a 400ml tank that lasts up to about 75 days depending on intensity and daily hours, so use is occasional - roughly a 2 to 2.5 month cycle at typical settings. The machine ships with four oils, and a multi-storey home scales use by one machine per floor.
Does the machine spray fragrance continuously?
No. It releases fragrance in short controlled bursts on a 1h, 4h, 8h or 24h timer, and you set the intensity from the app. So you decide how much it uses - a gentler setting makes a tank last longer, up to about 75 days.
How long does one tank of fragrance last?
A 400ml tank lasts up to about 75 days depending on your intensity setting and daily run hours. That makes a refill cycle roughly every 2 to 2.5 months at typical settings. The first tank ships with the machine.
How much fragrance does a multi-storey home use?
It scales with machines, not rooms. Each floor runs its own Vaayu drawing from its own 400ml tank, so a three-floor bungalow uses roughly three tanks over the same period - one machine per floor, since scent does not climb a staircase.
Can I make the fragrance last longer?
Yes. Run a gentler intensity and shorter daily hours and a 400ml tank lasts closer to the full 75 days. A stronger setting uses more. You control it entirely from the app.
