How much electricity does a home scent diffuser use? Very little. The SOSA Vaayu (₹11,999) is rated DC 12V/1A at 5W, which works out at roughly 1.5 units of electricity a month if you run it ten hours a day. In practical terms it is not a line item, and it is one of the reasons a schedule is preferable to switching a machine on and off by hand.
How long does a tank of fragrance oil last? The SOSA Vaayu holds 400ml and the product page states a tank lasts up to about 75 days, depending on intensity and run hours. That is roughly five fills a year at a moderate setting. Run it at a higher intensity or for longer daily hours and you will get fewer days from each fill, which is why an exact monthly cost cannot be quoted without knowing your settings.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, described by the manufacturer as approximately 2,000-3,000 sq ft, with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, Bluetooth app and onboard button control, 1h/4h/8h/24h timers with adjustable intensity, operation under 38dB, DC 12V/1A at 5W, dimensions 165 x 80.5 x 215mm at 0.9kg, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. It uses no water and no heat, so there is no dampness and no residue. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation. Prices and availability are subject to change - see the live product pages.
Almost every page you will find on this subject quotes a comfortable monthly figure, and almost none of them can know it, because the fragrance cost depends entirely on how hard and how long you run the machine. So here is the version I can stand behind: two fixed numbers, one variable one, and no invented averages.
Quick answers — read this first
How much does whole-home scenting cost in India? Three costs. The machine is one-time: a SOSA Vaayu is ₹11,999 and covers 1000m³, about 2,000-3,000 sq ft, so most homes need one. Electricity is 5W, which is roughly 1.5 units a month on a ten hour daily schedule. Fragrance is the variable one: a 400ml tank lasts up to about 75 days, which is roughly five fills a year, and fewer days per fill if you run higher intensity or longer hours.How much electricity does a home scent diffuser use?

How long does a tank of fragrance oil last? The SOSA Vaayu holds 400ml and the product page states a tank lasts up to about 75 days, depending on intensity and run hours. That is roughly five fills a year at a moderate setting. Run it at a higher intensity or for longer daily hours and you will get fewer days from each fill, which is why an exact monthly cost cannot be quoted without knowing your settings.
The short answer
Short answer: three costs. The machine is one-time: a SOSA Vaayu at ₹11,999, covering 1000m³ or about 2,000-3,000 sq ft. Electricity is 5W, roughly 1.5 units a month at ten hours a day. Fragrance is a 400ml tank lasting up to about 75 days, roughly five fills a year, fewer days at higher intensity or longer hours.
The pick: one SOSA Vaayu (₹11,999) for a floor of up to about 2,000-3,000 sq ft, run at a low intensity on two short daily windows to stretch each fill.
Next step: tell us your floor size, ceiling height and how many hours a day you want it running, and we will estimate the fills honestly - ask us what fits your home.

Two of the three costs are fixed numbers you can check on the product page. The third depends entirely on how hard and how long you run the machine, which is why we express it as fills a year rather than as a monthly bill.

Straight answer
What does whole-home scenting actually cost in India, all in?
Three separate costs, and they behave very differently. One, the machine, once. A SOSA Vaayu is ₹11,999. It is rated to 1000m³, described on the product page as about 2,000-3,000 sq ft, so the usual answer for an Indian apartment is one machine, and for a two-storey villa one per floor. This is the number people fixate on and it is the only one that is truly fixed. Two, electricity, and it is almost nothing. The Vaayu is DC 12V/1A at 5W. On a ten hour daily schedule that is roughly 1.5 units of electricity a month. Whatever your tariff, this is not a line item in a household budget. Three, fragrance oil, which is the only real running cost and the only variable one. The tank holds 400ml and lasts up to about 75 days depending on intensity and run hours. At a moderate setting that is roughly five fills a year. Run it at a higher intensity, or for fourteen hours a day instead of eight, and you will get meaningfully fewer days from each fill. That is why I will not quote you a rupees-per-month fragrance figure: the honest answer is fills per year, and where you land inside that range is decided by your settings, not by us. There are no hidden costs beyond those three - no water, no filters, no consumable pads, and the machine is waterless so there is no descaling either. What can change the total is a decision to run it harder than you need to; the level that reads as expensive is the lowest one you notice on entry, and it is also the cheapest. And the honest part before you spend. Three people should not buy this machine, and I would rather say so here than take the order. If you want one room lightly scented now and then, something small and cheap will serve you better. If the real problem is damp, a bin, a drain, a wardrobe or last night's cooking, fix the source - a machine will only give you both smells at once. And if you enjoy changing fragrance every fortnight, you will never get the thing a signature scent is actually for. SOSA's hotel-inspired fragrances are our own original interpretations of a style of scenting, composed in our own studio. SOSA is an independent Indian brand and is not affiliated with, or endorsed by, any hotel or hotel group. Ask us what fits your home; a portion of every order supports girl-child education through Nanhi Kali.
Rs 11,999 once, about 1.5 units of electricity a month at ten hours a day, and roughly five 400ml fills a year - fewer days per fill if you run it harder.
The one-time part of the cost: one SOSA Vaayu at ₹11,999, covering 1000m³ (about 2,000-3,000 sq ft), at 5W - roughly 1.5 units of electricity a month on a ten hour daily schedule - with a 400ml tank lasting up to about 75 days.

The three costs, separated honestly
Separate the three costs and the budgeting becomes simple. Two are known before you buy; one you control after.
1
The machine, once
₹11,999, and the coverage number that decides how many you need
The single biggest saving available in home scenting is buying fewer machines than you were planning to. The Vaayu is rated to 1000m³, about 2,000 to 3,000 sq ft, and most Indian apartments sit inside that from one well-placed point. People arrive intending to buy three - one for the hall, one for the living room, one upstairs - and in a flat that is simply spending twice over for a worse result, because three machines mean three fragrances arriving at different strengths. Measure the connected volume first.
Tip: length by width by height in metres. If the answer is under 1000, you need one machine.
2
The electricity, monthly
5W is roughly 1.5 units a month at ten hours a day
This is the cost people worry about and it is the one that does not matter. Five watts is less than most bedside lamps, and on a ten hour daily schedule it comes to roughly a unit and a half of electricity a month. There is no heater in the machine, because it does not use heat, and no pump running water, because it does not use water. If somebody has told you that a scent machine will add noticeably to your bill, they were describing a different kind of device.
3
The fragrance, in fills
The only real running cost, and the only one you control
A 400ml tank lasts up to about 75 days depending on intensity and run hours, which at a moderate setting is roughly five fills a year. That range is genuine, not a hedge: run at the lowest useful intensity for eight hours a day and each fill goes a long way, run at high intensity for fourteen hours and it will not. This is why I refuse to publish a rupees-per-month figure. Anybody who gives you one without asking your settings, your hours and your floor volume is guessing, and the guess will be wrong in whichever direction suits them.
Tip: the lowest intensity you can still notice on entry is both the best-smelling setting and the cheapest.
400ml, up to about 75 days a fill, with adjustable intensity that decides where in that range you land.

The SOSA principle
The expensive mistake in home scenting is not the machine. It is buying three of them for a house that needed one.
Two of the three costs are printed on the product page. The third one is a setting you choose.

Two things worth knowing before you budget. First, the cheapest version of this is usually the best-smelling one: a low intensity on two short daily windows both stretches a fill and reads better than a strong setting. Second, no amount of spending fixes a smell with a source - damp, a bin, a drain, a wardrobe or cooking needs the source dealt with first, and fragrance is not an air purifier. Three people should not buy this machine, and I would rather say so here than take the order. If you want one room lightly scented now and then, something small and cheap will serve you better. If the real problem is damp, a bin, a drain, a wardrobe or last night's cooking, fix the source - a machine will only give you both smells at once. And if you enjoy changing fragrance every fortnight, you will never get the thing a signature scent is actually for.

A note from Sonal
I have been asked for a monthly figure many times, and I have watched other people give one confidently. It is not a number anybody can know without knowing your floor volume, your intensity setting and your daily hours. So I give the parts instead, and let you assemble your own total.
The parts are simple. One Vaayu at ₹11,999, rated to 1000m³, about 2,000 to 3,000 sq ft, which for most Indian flats means one machine and not three. Five watts, roughly a unit and a half of electricity a month on a ten hour schedule. And a 400ml tank lasting up to about 75 days, so roughly five fills a year - fewer days per fill if you run it hard or long. Those are the only three costs there are.
And the honest part. Three people should not buy this machine, and I would rather say so here than take the order. If you want one room lightly scented now and then, something small and cheap will serve you better. If the real problem is damp, a bin, a drain, a wardrobe or last night's cooking, fix the source - a machine will only give you both smells at once. And if you enjoy changing fragrance every fortnight, you will never get the thing a signature scent is actually for. No budget covers a smell with a source: a home smells good because it is aired and clean first, then scented, and fragrance is a finish, not a fix, and not an air purifier. SOSA's hotel-inspired fragrances are our own original interpretations of a style of scenting, composed in our own studio. SOSA is an independent Indian brand and is not affiliated with, or endorsed by, any hotel or hotel group. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How much does whole-home scenting cost in India?
There are three costs. The machine is one-time: the SOSA Vaayu is Rs 11,999 and covers 1000 cubic metres, about 2,000 to 3,000 sq ft, so most homes need one. Electricity is 5W, which is roughly 1.5 units a month on a ten hour daily schedule. Fragrance is a 400ml tank lasting up to about 75 days, which is roughly five fills a year, and fewer days per fill at higher intensity or longer hours.
How much electricity does a scent machine use?
The SOSA Vaayu is rated DC 12V per 1A at 5W. On a ten hour daily schedule that is about 1.5 units of electricity a month, which is not a meaningful line in a household budget. There is no heating element and no water pump, because the machine uses neither heat nor water.
What is the monthly fragrance cost?
It cannot be stated honestly as a monthly rupee figure, because it depends on your intensity setting and your daily run hours. What can be stated is the fill: a 400ml tank lasts up to about 75 days, which is roughly five fills a year at a moderate setting. Run higher or longer and each fill covers fewer days. We will estimate your fills on a consultation once we know your floor volume and hours.
Are there any hidden running costs?
No water, no filters, no consumable pads and no descaling, because the SOSA Vaayu is a waterless nebuliser rather than a mist diffuser. The only ongoing cost is fragrance oil in the 400ml refillable tank, plus the 5W of electricity. The machine carries CE, RoHS and SGS certification and is made in India.
How can I make each fill last longer?
Run at the lowest intensity you can still notice when you walk in from outside, and use two short daily windows rather than leaving it on all day. That combination stretches a 400ml fill considerably and, more importantly, smells better: a settled low level reads as the smell of the house, while a strong setting reads as a shop.
