Is there a fixed monthly cost for a scent machine? No. The machine is a one-time buy with no compulsory subscription. Your only ongoing spend is fragrance oil bought occasionally as the tank runs down, plus minimal electricity, so the real monthly figure flexes with your settings.
Does running a scent machine use much electricity? No, the electricity cost is minimal. A cold-air diffuser sips power and often runs only in timed bursts rather than all day, so it is a small part of a home's running costs.
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, double-height or duplex penthouse may need more than one machine or the larger Angaan (₹25,999, ~8,000-10,000 sq ft) or Meenar (₹38,500, ~12,000-18,000 sq ft); 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 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.
Everyone wants a tidy monthly figure, and I would rather be honest than invent one: after the machine, the ongoing cost is occasional oil and a little electricity, and it flexes with how strong and how long you run it.

How much does it cost to keep a penthouse smelling good every month? There is no fixed monthly fee. After a one-time SOSA Vaayu (Rs 11,999), which ships with 400ml of oil included, a 400ml tank lasts up to about 75 days depending on intensity and daily hours - so refills are occasional, roughly every 2 to 2.5 months at typical settings, and electricity use is minimal. The exact monthly cost depends on your intensity, hours and refill size, and is best confirmed with SOSA and on the product pages. Oils start from Rs 299.Is there a fixed monthly cost for a scent machine? No. The machine is a one-time buy with no compulsory subscription.

The short answer
Short answer: there is no fixed monthly fee - after the one-time Vaayu (Rs 11,999, first tank included), a 400ml tank lasts up to ~75 days, so refills are occasional and electricity is minimal; exact monthly cost depends on intensity, hours and refill size.
The pick: one SOSA Vaayu (₹11,999) for an open-plan penthouse up to ~2000-3000 sq ft (1000m3), with a hotel-inspired signature scent; two Vaayu or the Angaan (₹25,999) for a soaring, 4000+ sq ft or duplex home.
Next step: shop the SOSA Vaayu, or book a quick consultation to size a large or duplex penthouse.
In this guide
Scenting a penthouse well is two decisions: one signature fragrance, and a machine sized to the space. A single SOSA Vaayu cold-air diffuser fills an open-plan penthouse of up to about 1000m3 (roughly 2000-3000 sq ft) with a clean, hotel-inspired scent, on a timer. A very large, double-height or duplex penthouse is sized to its zones - two Vaayu, or a step up to the larger Angaan - because fragrance is about the volume of air, and it does not travel up a staircase on its own. When in doubt, a quick consultation sizes it for you.

Straight answer
What does it really cost each month to keep a penthouse smelling good?
Honestly, there is no single fixed monthly fee - and be wary of anyone who quotes one. After a one-time SOSA Vaayu (₹11,999), which ships with 400ml of oil included, a 400ml tank lasts up to about 75 days depending on your intensity setting and daily hours. So refills are occasional - roughly every 2 to 2.5 months at typical hours - and the exact monthly cost depends on your intensity, hours and refill size. Electricity use is minimal, and there is no compulsory subscription. Oils start from ₹299, and the exact refill price and monthly figure are best confirmed with SOSA and on the product pages. For a larger home, a consultation helps you plan it.
There is no fixed monthly fee - after the one-time Vaayu, a 400ml tank lasts up to ~75 days, so refills are occasional and electricity is minimal; exact monthly cost depends on your settings.
For most penthouses the answer is one SOSA Vaayu - a waterless cold-air diffuser that carries a clean, hotel-inspired signature scent across an open-plan home of up to about 2000-3000 sq ft, on a timer, from one discreet machine. A very large, double-height or duplex penthouse is simply sized up - two Vaayu, or the larger Angaan. It ships with four hotel-inspired oils, so you can find your signature from day one.

Why there is no single fixed monthly number
A monthly figure feels reassuring, but for a scent machine it would be a guess dressed up as a fact. Here is the honest way to think about the running cost instead.
1
The machine is done
A one-time cost, not monthly
The Vaayu is Rs 11,999 paid once, and the first 400ml tank is in the box. That means your monthly ongoing cost starts at effectively nothing for the first couple of months while you run the included oil.
Tip: most of what people imagine as a monthly cost is really a one-time purchase you have already made.
2
Oil is occasional
Refills every couple of months
A 400ml tank lasts up to about 75 days depending on intensity and hours, so you re-buy oil only every 2 to 2.5 months at typical settings, not every month. Oils start from Rs 299, and the exact refill price and monthly figure are best confirmed with SOSA.
3
It flexes with you
Settings decide the number
Run it stronger and for more hours and a tank empties sooner; run it gently on a timer and it lasts longer. That is why an honest answer is a range tied to your habits, not a fixed rupee figure. Electricity on top is minimal.
Tip: the running cost is yours to set - lighter settings simply stretch each tank further.
The SOSA principle
I could give you a neat monthly number, but it would be fiction - the truth is that a tank lasts up to about 75 days and the rest depends entirely on how you like to run it.
What I can promise is that it is a modest, occasional cost, not a fixed subscription, and it stays firmly in your control.
Sizing the running cost to your penthouse
The running cost scales with the size of the home, because a larger volume of air runs more machine. Here is how to think about it across a penthouse.
The SOSA scent edit
Running cost, sized to the home
| Scent | Why it suits the mood |
|---|---|
| Open penthouse up to ~2000-3000 sq ft | One Vaayu; a 400ml tank lasts up to ~75 days, so oil is an occasional buy from Rs 299. |
| 4000 sq ft or very open | Two Vaayu or the Angaan; more machines mean proportionally more oil, still occasional not monthly. |
| Duplex or multi-floor | One machine per floor or zone; plan oil per machine, and a consultation helps you budget it. |
A larger home simply runs more machine, so a soaring or 4000+ sq ft space on the Angaan (₹25,999), or a duplex on one Vaayu per floor, uses proportionally more oil - still occasional rather than a fixed monthly bill. For a single closed room, a compact Sukoon (₹1,899) uses very little. Because the number depends on your layout, settings and refill size, a quick consultation is the best way to plan a realistic budget.
The invisible finishing touch
One SOSA Vaayu gives a penthouse a clean, five-star signature scent across the whole open floor - ₹11,999, app & timer, ships with four hotel-inspired oils. Larger machines for a soaring or duplex home.
The most honest thing I can say about monthly cost is that you control it - lighter settings stretch each tank, and there is no subscription quietly ticking in the background.

The SOSA penthouse 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 penthouse up to ~2000-3000 sq ft, and the Angaan or Meenar for a soaring, 4000+ sq ft or multi-floor residence. A scent works alongside good ventilation, and the simplest way to size a large or duplex home is a quick consultation. Here is the full edit.
The SOSA penthouse scenting edit
One signature scent, the right machine for your space - a Vaayu for an open penthouse, more for a soaring or duplex home
| Machine | Best for | Why it works | From |
|---|---|---|---|
 SOSA Vaayu
|
An open-plan penthouse up to ~2000-3000 sq ft (1000m3) | 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 soaring double-height or 4000+ sq ft penthouse | HVAC nebulising diffuser for a very large volume of air | ₹25,999 |
 SOSA Sukoon
|
A single closed bedroom, study or dressing 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-plan penthouse of up to about 1000m3 (roughly 2000-3000 sq ft). A 4000 sq ft or very open penthouse wants two Vaayu placed in different zones, or a step up to the Angaan. A double-height living room holds far more air than its floor suggests, so place the machine well and consider the Angaan for a soaring volume. A duplex needs one machine per floor - scent does not climb a staircase on its own. Keep one signature fragrance throughout, and if you are unsure, a quick consultation sizes it. One honest note: a scent makes a beautiful, well-aired home feel five-star; it works alongside good ventilation and does not mask a closed-up or musty smell.

A note from Sonal
A penthouse is designed down to the last detail - the light, the materials, the view - and then most people 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, a penthouse greets you and your guests with a clean, quietly luxurious signature the moment the lift doors open.
The mistake I see is scattering reed diffusers on every table, which clutters beautiful interiors and still leaves the space smelling uneven. A single Vaayu cold-air diffuser does the opposite: one signature scent, carried evenly across an open-plan penthouse of up to about 2000-3000 sq ft, from one discreet machine on a timer. It is the invisible finishing touch.
My only rule is to size it to the space honestly. A very large, double-height or duplex penthouse holds more air than its floor plan suggests, so it is two machines or a larger one, not one working too hard. And a scent enhances a clean, well-aired home - it is a luxury, not a cover-up. Everything is made in India, and for a big or duplex penthouse a quick consultation gets the sizing exactly right.
Frequently asked questions
How much does it cost to keep a penthouse smelling good every month?
There is no fixed monthly fee. After a one-time Vaayu (Rs 11,999) with the first 400ml tank included, a tank lasts up to about 75 days depending on intensity and hours, so refills are occasional - roughly every 2 to 2.5 months at typical settings - and electricity is minimal. The exact monthly figure depends on your settings and is best confirmed with SOSA.
Is there a fixed monthly subscription?
No. The machine is a one-time purchase with no compulsory subscription. Your only ongoing cost is fragrance oil bought occasionally as the tank runs down, plus a little electricity, so nothing recurs automatically.
Why can't you give one exact monthly number?
Because it would be a guess. A 400ml tank lasts up to about 75 days, but whether that is closer to two months or two-and-a-half depends on your intensity setting, daily hours and refill size. An honest answer is a range tied to how you run it.
How much electricity does it use?
Minimal. A cold-air diffuser sips power and often runs in timed bursts rather than all day, so it is a very small part of a home's running costs. There is no heater or water pump drawing significant load.
How can I keep the running cost down?
Run it on a timer and a moderate intensity rather than full strength all day - lighter settings stretch each 400ml tank further, so you buy oil less often. The first tank is already included with the machine.
