I can give you a worked sum on this, and I will. What I cannot give you is the conclusion people want from it, because the two most important numbers in the calculation are ones only your own purchase records hold.
Quick answers — read this first
What is the actual cost difference? It depends on numbers I do not have, so let me be exact about which side I can state. One SOSA Vaayu is ₹11,999, once, with 4 × 100ml of oil in the box and a 400ml tank that runs 90+ days a fill depending on intensity and hours. The other side of the sum is what your clinic currently gets through in cans, and only your invoices know that. I will not quote anybody else's product price, so the arithmetic below leaves that blank for you to fill.

So how do I actually work it out? Pull three months of purchase records, count every can bought for the clinic including the ones staff buy out of petty cash, and divide by three. That is your monthly figure. Then divide ₹11,999 by it and you have the number of months at which the two lines cross. That number is arithmetic and nothing more. It moves with your run hours, your intensity setting and how heavily your team actually sprays, and none of those are fixed. Treat the answer as an illustration you produced, not as a projection I gave you.

Is the machine cheaper in the end? It might be, and I am deliberately not going to say it is. The two things are not even doing the same job - a can is a burst that spikes and fades, a machine holds one low level during clinic hours - so comparing their costs compares two different products. If your clinic gets through two cans a year, the lines never cross and you should not buy the machine. If your patient-facing area is under about 750 sq ft, the honest hardware side is a SOSA Sukoon at ₹1,899 and the sum changes completely.
The short answer
Short answer: a sum you have to complete yourself. The machine side I can state: one SOSA Vaayu at ₹11,999 once, with 4 × 100ml included and a 400ml tank running 90+ days a fill. The freshener side is whatever your own three-month purchase records show, which I will not guess and will not quote from another brand. Divide ₹11,999 by your monthly figure to see where the lines cross - that is arithmetic, not a saving, and it moves with run hours and intensity.
The pick: one SOSA Vaayu (₹11,999) for a clinic past roughly 1,500 sq ft, or one SOSA Sukoon (₹1,899) where the patient-facing side is a single reception - which changes the arithmetic far more than anything else on this page.
Next step: send three months of your own purchase records and the floor plan, and we will complete the sum with your numbers in it and tell you honestly what it does and does not show - Ask for a clinic scenting plan.
Fresheners against one machine - the sum, and its limitsMachine side: ₹11,999 once, 4 × 100ml in the box400ml tank, 90+ days a fill, no refill sold separatelyFreshener side: only your own invoices know itDivide, and you get a crossover in monthsThat is arithmetic. It is not a saving and not a return
Both halves of this sum move - one with your run hours and intensity, the other with how heavily your team sprays. Treat the result as an illustration you produced.
The one-time side of the sum - tap for the specification
Straight answer
What is the cost difference between constantly buying room fresheners and using one dedicated commercial scent system?
Let me set out both sides honestly, and then be equally honest about what the sum proves. The side I can state precisely: one SOSA Vaayu is ₹11,999, paid once. It ships with 4 × 100ml of hotel-inspired oil, and the 400ml tank runs 90+ days a fill, depending on the intensity you set and how many hours a day it runs. So the first three months and more after switch-on cost nothing further. Beyond that I have to be careful rather than convenient: SOSA does not currently sell a cold-air refill oil separately, the 400ml in the box is the supply, and further refills should be confirmed with SOSA rather than assumed. If your patient-facing area is under about 750 sq ft, the hardware side is a SOSA Sukoon at ₹1,899 instead, which changes the whole calculation more than any other single factor. The side I cannot state: what your clinic currently spends on cans. I will not quote a competing product's price on this page, and I will not guess at your consumption, because both would make the sum look authoritative when it is not. Get it yourself: pull three months of purchase records, count every can bought for the clinic - including the ones the front desk buys out of petty cash and never invoices properly, which is where most clinics under-count - and divide by three. That is your monthly figure. Now the arithmetic, and please read it as arithmetic: ₹11,999 divided by your monthly figure gives the number of months at which the two lines cross. If your clinic gets through a lot of cans, that number is small. If it gets through two cans a year, the lines never cross at all and you should not buy the machine - I would rather write that sentence than sell one on a sum that does not support it. Three things move the result and none of them are fixed: your run hours, your intensity setting, and how heavily your team actually sprays. There is also a deeper problem with the comparison, which is that the two things are not the same product. A can is a burst - a spike that fades within the hour and gets repeated whenever somebody notices - while a machine holds one low level through clinic hours and can be locked so nobody raises it. You are comparing an event with a condition. And if the reason you are buying cans in the first place is that the clinic smells of something, then neither answer is right, because fragrance is never used to cover another smell and the honest fix is to trace the source with your facilities team and your cleaning contract. The standing limits do not change with the arithmetic: this is an interior decision with no clinical or therapeutic claim of any kind, it works alongside cleaning and ventilation rather than instead of them, procedure, recovery and photography rooms stay unscented, and no one can promise you that any of this returns money to the practice. Ask for a clinic scenting plan and send the three months of records - we will do the sum with your numbers in it.
The machine side is ₹11,999 once, with 4 × 100ml included and a 400ml tank running 90+ days a fill. The freshener side is whatever your own three months of invoices show. Divide and you get a crossover in months - which is arithmetic, not a saving.
The one-time half of the sum. One SOSA Vaayu - ₹11,999, with 4 × 100ml of oil in the box and a 400ml tank running 90+ days a fill. No cold-air refill is sold separately, so confirm further refills with SOSA. Under about 750 sq ft, the Sukoon at ₹1,899 changes the sum entirely.

The machine, by clinic size

Which machine you are putting into the sum matters more than any other variable in it, and it is decided by patient-facing floor area rather than by how much you currently spend on cans.

SOSA Vaayu
Clinics past about 1,500 sq ft
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³, about 2,000-3,000 sq ft. ₹11,999 once, shipping with 4 × 100ml of oil; the 400ml tank runs 90+ days a fill depending on intensity and hours. Timers and a key-lock, which is what makes consumption bounded rather than a matter of who is on shift.
From ₹11,999
SOSA Sukoon
Clinics under about 750 sq ft - this changes the sum
SOSA Sukoon
Ultrasonic cool-mist diffuser covering roughly 270-320 sq ft, supplied with three 15ml hotel-inspired fragrances, at ₹1,899. At a sixth of the hardware cost, the crossover arithmetic looks completely different - and for a single reception this is the honest machine anyway.
From ₹1,899
SOSA Vaayu
The one-time hardware side of the comparison
SOSA Vaayu
1000m³ coverage (about 2,000-3,000 sq ft), 400ml tank running 90+ days a fill, Bluetooth app and 1h/4h/8h/24h timers, adjustable intensity, under 38dB, 5W, freestanding or wall and HVAC mount, auto-stop and key-lock. CE, RoHS and SGS certified - electrical and compliance marks, not medical approvals. Made in India.

How to do the sum properly

Three steps, and a warning attached to each. The warnings matter more than the steps, because the steps are easy and the conclusion is where people overreach.

1
Count your own cans, from records
The figure in your head is almost certainly too low
Do not estimate this. Pull three months of purchase records and count every can bought for the clinic, then divide by three. The number people carry in their heads is usually well under the real one, for a simple reason: fresheners are a petty-cash purchase. They get bought by whoever notices the shelf is empty, they rarely appear on a proper invoice, and in a clinic with more than one site nobody is aggregating them. Include cans bought for washrooms and staff areas if they come out of the same budget, and include the ones bought in a hurry before a busy clinic day. Only your own records can produce this number, which is exactly why I am not going to supply one.
Tip: Ask the front desk what they actually buy rather than reading the ledger alone. The ledger is usually the smaller of the two figures.
SOSA Vaayu
One Vaayu ₹11,999, set once and left alone, is the whole hardware side of this.

Do the division, and label it honestly
A crossover point is not a payback and not a saving
Take ₹11,999, divide by the monthly figure you just produced, and you have the number of months at which the two lines meet. That is the whole calculation and it is genuinely useful for a decision - but it is a description of two spending patterns, not a return. Nothing here comes back to the practice, nothing is earned, and no one can promise ambient scent moves any number your clinic runs on. Three variables move the crossover: run hours, intensity setting, and how heavily your team sprays, which is seasonal and personal. Run the sum twice, once at your heaviest month and once at your lightest, and you will see the honest width of the answer.
Tip: If the two lines cross beyond about two years on your own numbers, buy the machine for the room rather than for the sum.

Notice you are comparing two different things
A burst that fades is not the same product as a held level
An aerosol is an event: someone sprays, the room spikes well above the level any clinic should sit at, and an hour later it has gone, so it gets repeated. A dedicated machine holds one low level through clinic hours, on a timer, with a key-lock so nobody raises it. That difference is the reason a clinic ends up buying cans continuously in the first place, and it is also why a pure cost comparison flatters neither side properly. And if the cans are being bought because something in the building smells, stop the comparison entirely: fragrance is never used to cover another smell, and the fix is a drainage, damp, ventilation or cleaning matter for your facilities team rather than a purchase.

The SOSA principle
I can show you the arithmetic and I can tell you what it is worth: it describes two spending patterns and nothing else. It is not a payback, not a return, and not a saving.
The two numbers that decide the answer - your consumption and your run hours - are both yours, and both of them move.

Here is the sum as I would set it out on paper, with the blanks left where only your records can fill them.

The SOSA plan
The comparison as a worked illustration, not a projection
The line What to do
Your current freshener spend
Three months of purchase records, every can counted including petty cash, divided by three. Your number, not mine - no competing price is quoted here.
SOSA VaayuThe machine, once
₹11,999 for a clinic past about 1,500 sq ft. One payment, one unit, on the reception air path.
SOSA SukoonThe machine, for a small clinic
₹1,899 where the patient-facing side is a single reception under about 750 sq ft. This changes the sum more than anything else in it.
What comes in the box
4 × 100ml of oil with the Vaayu, and a 400ml tank running 90+ days a fill depending on intensity and run hours. Three 15ml fragrances with the Sukoon.
After the first fill
No cold-air refill oil is currently sold separately - the box is the supply, and further refills should be confirmed with SOSA rather than assumed.
The crossover
₹11,999 divided by your monthly figure, in months. Arithmetic only. It moves with run hours, intensity and consumption, and it is not a saving or a return.

If the real question is proportion rather than crossover - what this costs against what the clinic itself cost - that is handled in whether scenting is worth adding to a twenty-lakh clinic interior, and the answer there is also carefully not a business case. And if you are a single-surgeon practice rather than a group, the arithmetic looks entirely different, as set out in whether professional scenting is worth it for a solo hair-transplant surgeon. SOSA is independent and not affiliated with any hotel.

SOSA Vaayu
What bounds the consumption: 1h/4h/8h/24h timers and a key-lock, so usage is set once rather than decided by whoever is on shift. ₹11,999.
One price, once, and a tank that lasts a quarter
SOSA Vaayu ₹11,999 ships with 4 × 100ml of oil and a 400ml tank running 90+ days a fill - the only half of this sum anybody can state for you.
See the SOSA Vaayu Book a scenting plan
I can hand you the arithmetic. I cannot hand you the conclusion, because the two numbers that decide it are sitting in your own purchase file.

Complete the sum with your own records and label the result as arithmetic rather than as a return. Three limits stand whatever the numbers say: this is an interior decision with no clinical or therapeutic claim of any kind; it works alongside cleaning and ventilation, never instead of them, and is never used to cover another smell; and no one can promise ambient scent returns money or moves any number the practice runs on. Cold-air refill oil is not currently sold separately, and warranty, maintenance, installation, spare parts, bulk pricing and corporate invoicing are not published - confirm all of them with SOSA before you build them into a comparison. Ask for a clinic scenting plan before you spend anything.

A note from Sonal

This is the question I am asked most often by founders who have already decided and want a justification, and it is the one where I am most careful. I can give you a sum. What I will not do is quote another brand's price to make my side look better, or invent a consumption figure for your clinic, or call the result a saving. Two of the numbers in this calculation belong to you and both of them move, so anything I presented as a projection would be a decorated guess.

The part I can be exact about is small and useful. One Vaayu is ₹11,999, paid once. It arrives with 4 × 100ml of oil and the 400ml tank runs 90 or more days on a fill, depending on how hard and how long you run it, so the first quarter after switch-on costs nothing further. Beyond that, I have to tell you that no cold-air refill is currently sold separately and that further refills are something to confirm with us rather than assume - which is not the answer a comparison page usually gives, and is the true one. On the reed side the refill costs are published, 300ml at ₹2,399 and 500ml at ₹3,499, oil only, and for a small waiting area that route can be the whole answer.

So: count your cans from three months of records, divide, and divide ₹11,999 by the result. If the lines cross soon, the decision is easy. If your clinic gets through two cans a year, they never cross and you should not buy the machine - I would rather say that than have you buy one on a sum that does not hold. And whichever way it lands, the machine goes in the reception and the procedure, recovery and photography rooms get nothing at all. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

Frequently asked questions

What is the cost difference between constantly buying room fresheners and using a dedicated commercial scent system?
It is a sum you have to complete yourself, and I would rather set it out than pretend to a figure. The machine side is stateable: one SOSA Vaayu at Rs 11,999 once, shipping with 4 x 100ml of oil and a 400ml tank that runs 90 or more days a fill. The other side is whatever your own three months of purchase records show. Divide Rs 11,999 by your monthly figure to find the crossover in months - and treat that as arithmetic rather than a saving.
Why will you not just tell me what a can costs?
Because quoting a competing product's price would make my arithmetic look authoritative when the important variables are still yours, and because I do not think it is my place to price somebody else's product. Your own records will give you a far better number than any average I could offer, since consumption varies enormously with the size of the clinic, the season, and how many people are allowed to buy cans on petty cash.
What are the ongoing costs of the machine itself?
The SOSA Vaayu ships with 4 x 100ml of oil and its 400ml tank runs 90 or more days a fill, depending on the intensity you set and how many hours a day it runs, so nothing further is needed for the first quarter and usually longer. Beyond that, no cold-air refill oil is currently sold separately and further refills should be confirmed with SOSA. Warranty, maintenance, installation and spare parts are not published either.
Does the crossover point prove the machine pays for itself?
No, and I would not describe it that way. A crossover is a comparison of two spending patterns, not a return - nothing comes back to the practice and nothing is earned. It also compares two different products: an aerosol is a burst that spikes and fades and gets repeated, while a machine holds one low level through clinic hours with a timer and a key-lock. No one can promise ambient scent moves any number your clinic runs on.
When should I not buy the machine at all?
Two cases. If your clinic gets through very few cans, the lines never cross and the machine should be bought for the room or not at all. And if the reason you buy fresheners is that something in the building smells, neither answer is right - fragrance is never used to cover another smell, and the fix is a drainage, damp, ventilation or cleaning matter for your facilities team. Under about 750 sq ft, the honest hardware is a Sukoon at Rs 1,899 anyway.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the planning advice applies to any brand.

Facts verified 5 September 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 adjustable intensity, a 400ml refillable tank lasting 90+ days a fill depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB at 5W, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification, which are electrical and compliance marks and not medical approvals. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering roughly 270-320 sq ft and is supplied with three 15ml fragrances; the water-based Hotel Collection (₹299 / ₹999 / ₹1,799) is an ultrasonic fragrance and is not a refill for a waterless cold-air machine. SOSA reed diffusers are alcohol-free and phthalate-free, with 50ml lasting about 6-8 weeks and 130ml about 14-18 weeks. Cold-air refill oil for the Vaayu is not currently sold separately - the machine ships with 400ml included and further refills should be confirmed with SOSA. Warranty, annual maintenance, installation and bulk terms are not published and should be confirmed before ordering. Ambient scent is an interior and hospitality decision: it makes no clinical, therapeutic or wellbeing claim, it works alongside proper ventilation, cleaning and infection control and is never a substitute for any of them, it is never used to mask another smell, and no claim is made that fragrance influences a patient's decision or any commercial outcome. Clinical areas including procedure, post-procedure and photography rooms are left unscented, and the treating clinician's judgement overrides any scenting plan in their own room. 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.
