Is there a monthly subscription or fixed running cost? No compulsory subscription. You buy the machine once, and your only ongoing cost is fragrance oil, which starts from Rs 299. How long a tank lasts depends on your intensity setting and daily hours - the 400ml it ships with lasts up to about 75 days as a guide, so we do not quote a fixed monthly figure.
Does it use much electricity? Very little. It is a low-draw cold-air machine that only runs on the schedule you set, so electricity is a minimal, qualitative cost rather than a meaningful line item.
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, and under-38dB operation. Its automation is via Bluetooth app control and built-in 1h/4h/8h/24h timers: you schedule when it runs directly through its own app or timer settings. It is not a hub-integrated, Wi-Fi, or voice-assistant device, and SOSA does not claim it connects to third-party smart-home platforms, voice assistants (such as Alexa, Google Assistant or Siri) or automation hubs; where it appears "alongside" a smart home, that means it runs on its own schedule next to other devices, not integrated into one system. Fragrance is sized to the volume of air, 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 home generally needs one machine per floor - scent does not travel up a staircase on its own. A signature scent enhances a clean, well-ventilated home; it does not remove a musty or closed-up smell, and 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.
It is the fair question nobody answers straight: what does it actually cost to have your whole home smell like a five-star hotel, on its own, every day? Here is the honest version - the real anchors, the sensible way to reason about running cost, and the numbers we will not pretend to know.

The short answer

Next step: shop the SOSA Vaayu, or book a quick consultation to size a large or multi-storey home.
In this guide
You already automate the invisible parts of the day - lights, curtains, temperature. Fragrance is the one most people leave manual. The SOSA Vaayu automates it: set a schedule once from its Bluetooth app, or use the built-in 1h/4h/8h/24h timers, and your home fills with a clean, hotel-inspired scent on its own - before you arrive, before guests, every day. It runs alongside your other smart devices, each on its own schedule (it is controlled by its own app and timers, not wired into a central hub). One Vaayu covers an open floor of up to about 1000m3 (roughly 2000-3000 sq ft); a multi-storey villa runs one per floor. A quick consultation sizes a large home.

Straight answer
How much does an automatic whole-home fragrance system really cost?
Honestly, the cost is mostly the machine, and it is a one-time purchase. One SOSA Vaayu is ₹11,999 and covers an open floor up to about 1000m3 (roughly 2000-3000 sq ft). A whole-home system is simply one machine per floor - a two-floor home is two Vaayu units, a three-floor home is three - because scent does not climb a staircase, so there is no single fabricated total; it depends on your floors. After that, your only ongoing cost is fragrance oil, which starts from ₹299. Each Vaayu ships with 400ml (about one full tank) that lasts up to around 75 days depending on your intensity setting and daily run hours - which is why we will not quote you a fixed monthly rupee figure or a made-up per-day amount; it genuinely varies with how you run it. There is no compulsory subscription, and electricity is minimal for a low-draw cold-air machine that only runs on your schedule. A very large or double-height floor steps up to the Angaan (₹25,999). Book a consultation for a per-floor estimate, or shop the Vaayu.
Cost is mostly the machine - one SOSA Vaayu (Rs 11,999) per floor - plus oils from Rs 299, one-time buy, no subscription.
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 villa is one machine 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.

What actually goes into the cost, honestly
A lot of fragrance-cost articles invent a tidy monthly number. We will not, because it would not be true. Here is what the cost honestly breaks into.
1
The machine (one-time)
One Vaayu per floor
The main cost is the machine itself: one Vaayu at Rs 11,999 per open floor. A whole-home system is one per floor, so your total is the machine multiplied by your number of floors - there is no single universal figure because homes differ.
Tip: count your floors and multiply by the machine price - that is the bulk of the cost, once.
2
The oil (ongoing)
From Rs 299, varies with use
Your only real running cost is fragrance oil, from Rs 299. The 400ml that ships with each Vaayu lasts up to about 75 days as a guide, but the true figure depends on your intensity setting and daily hours, so treat 75 days as a reference, not a promise.
3
Electricity and subscription
Minimal, and none required
Electricity is minimal - it is a low-draw cold-air machine that only runs when scheduled. And there is no compulsory subscription: you own the machine and simply buy oil when you need it.
Tip: there is no forced monthly plan - you buy oil only when a tank runs low.
The SOSA principle
The honest answer to running cost is a range, not a number - because it depends entirely on how strong and how often you like your home to smell, which only you can decide.
What we can promise is the shape of it: a one-time machine per floor, oil from Rs 299, minimal electricity, and no subscription pulling from your account each month.
Working out the cost for your home
So the way to estimate your cost is to count floors for the one-time part and think about intensity for the ongoing part. Here is the frame.
The SOSA scent edit
How the cost breaks down
| Scent | Why it suits the mood |
|---|---|
| The machine (one-time) | One SOSA Vaayu (Rs 11,999) per open floor up to ~2000-3000 sq ft; a very large or double-height floor steps up to the Angaan (Rs 25,999). |
| The oil (ongoing) | From Rs 299. Ships with 400ml (about one tank), which lasts up to ~75 days depending on intensity and hours - a guide, not a fixed monthly cost. |
| Electricity and subscription | Electricity is minimal; there is no compulsory subscription - a one-time buy, then oil as needed. |
To estimate your own number, count your floors and multiply by one Vaayu (₹11,999), stepping any very large or double-height floor up to the Angaan (₹25,999). For the ongoing part, budget fragrance oil from ₹299 and treat the ~75-day tank life as a reference that shifts with your intensity and hours. The cleanest way to get a real per-floor figure for your home is a quick consultation.
Set it once, forget it
Schedule it once from the app or a timer and the SOSA Vaayu fragrances your home on its own - ₹11,999, Bluetooth app + 1h/4h/8h/24h timers, ships with four hotel-inspired oils.
We could hand you a neat monthly number, but it would be fiction. The truth is a one-time machine per floor, oil from Rs 299, and no subscription - and that honesty is the point.

The SOSA automatic-scenting 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 villa), 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 automatic-scenting edit
One signature scent, scheduled from the app - a Vaayu per open floor, 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 villa | 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 automate and size it: the Vaayu is scheduled from its Bluetooth app or built-in 1h/4h/8h/24h timers - set it once to run before you arrive, before guests, or on a daily rhythm, and it is hands-free from then on. It runs on its own schedule alongside your smart lights and speakers rather than wired into a central hub or voice assistant. On sizing, fragrance is about the volume of air: one Vaayu fills an open floor of up to about 1000m3 (roughly 2000-3000 sq ft), a multi-storey villa runs one machine per floor (scent does not climb a staircase on its own), and a very large or double-height floor steps up to the Angaan. A closed bedroom or study can take a compact Sukoon. One honest note: a scent enhances a clean, well-aired home and works alongside good ventilation - it is a luxury, not a cover-up. Unsure? A quick consultation sizes it.

A note from Sonal
If you have already automated your lights, your curtains, your AC, you understand the real luxury of a smart home: the best things happen without you thinking about them. Fragrance is the one part almost everyone still does by hand - a spray here, a reed there - and it is the easiest and most rewarding thing to automate. A home that greets you with a clean, hotel-inspired scent the moment you walk in, every single day, without a thought, is a small daily luxury you never tire of.
That is exactly what the Vaayu does. You set a schedule once from its Bluetooth app, or use the built-in 1h/4h/8h/24h timers, and it runs itself - before you get home, before guests arrive, on whatever rhythm suits your day. It sits happily alongside your smart lights and speakers, each on its own schedule, so an arrival can feel genuinely five-star.
One honest note on how it works: the Vaayu is controlled by its own Bluetooth app and built-in timers - you schedule it directly, rather than wiring it into a central smart-home hub or a voice assistant. And size it to the space: one machine per open floor up to about 2000-3000 sq ft, one per floor of a multi-storey villa. A scent enhances a clean, well-aired home; it is a luxury, not a cover-up. Everything is made in India, and a quick consultation sizes a large home.
Frequently asked questions
How much does an automatic whole-home fragrance system cost?
The core cost is the machine: one SOSA Vaayu (Rs 11,999) per open floor. A whole-home system is one machine per floor, so a two-floor home is two units. Oils start from Rs 299, and it is a one-time purchase with no compulsory subscription.
Is there a fixed monthly running cost?
No, and we will not invent one. Your only ongoing cost is fragrance oil from Rs 299. The 400ml each Vaayu ships with lasts up to about 75 days as a guide, but the real figure depends on your intensity setting and daily hours, so it varies from home to home.
Is there a subscription I have to pay?
No. There is no compulsory subscription. You buy the machine once and own it, then buy oil only when a tank runs low. Refills start from Rs 299.
How much electricity does it use?
Very little. It is a low-draw cold-air machine that only runs on the schedule you set, so electricity is a minimal, qualitative cost rather than a meaningful monthly line item.
How do I get an accurate cost for my specific home?
Count your floors for the one-time machine cost - one Vaayu per open floor, Angaan for a very large or double-height floor - and budget oil from Rs 299 for the ongoing part. A quick consultation gives you a precise per-floor estimate.
