Forecasting a refill budget goes wrong when it is treated as a flat monthly rate, because that number does not really exist - it depends on intensity and run hours. The number that is genuinely fixed, and the one worth forecasting from, is how often a tank needs refilling in the first place.
Quick answers — read this first
How do I forecast fragrance refill costs for a clinic diffuser? Forecast by cadence first, not by a flat rupee figure, because cadence is the number that is actually fixed by the hardware. The SOSA Vaayu's 400ml tank lasts up to about 75 days depending on intensity and run hours, so a reception on a normal ten-hour schedule refills roughly four to five times a year. The exact oil cost per refill depends on the intensity you run and the fragrance chosen, so it is confirmed on a consultation rather than quoted as a single number here.

What does fragrance cost for a single consultation cabin? This is the clearest figure in the range. A SOSA Sukoon (Rs 1,899, a 500ml ultrasonic diffuser) runs on water-based fragrance from the Hotel Collection, priced from Rs 299 for a 15ml bottle, with 100ml and 300ml sizes also available for a cabin used more heavily. A single cabin on a low setting can run for weeks on the smaller size.

Does refill frequency change with the settings on a scent machine? Yes, meaningfully. A tank refilled at the lowest usable intensity - which is also the honest setting for a clinic, since restraint reads as confidence in a medical space - lasts longer than the same tank run at a high setting for long hours. That is why the SOSA Vaayu's 400ml tank is described as lasting up to about 75 days, with the actual figure for any one clinic depending on its intensity and daily run hours.
The short answer
Short answer: forecast by cadence, not a flat monthly rate. The SOSA Vaayu's 400ml tank lasts up to about 75 days, so a reception on a normal schedule refills roughly four to five times a year - the exact oil cost per refill is confirmed on a consultation since intensity and hours change it. For a single cabin on a SOSA Sukoon, Hotel Collection fragrance is the clearest figure here, from Rs 299.
The pick: forecast a reception on one SOSA Vaayu (₹11,999) at roughly four to five refills a year, and a single cabin on a SOSA Sukoon (₹1,899) against Hotel Collection fragrance from ₹299.
Next step: tell us your intensity and daily run hours and we will confirm the exact refill cadence and cost - ask for a clinic scenting plan.

Straight answer
How should a clinic forecast fragrance refill costs?
Forecast by cadence - how often a refill is needed - before trying to attach a rupee figure to it, because cadence is the number the hardware actually fixes. One SOSA Vaayu has a 400ml tank that lasts up to about 75 days, depending on the intensity it is run at and the daily hours it operates. On a typical ten-hour clinic day at a low, honest intensity, that works out to a reception refilling the tank roughly four to five times a year. That frequency is the useful planning number: put four to five refill dates in the practice diary for the year, rather than trying to budget a monthly average that will not match any actual month, since a tank that lasted 75 days does not need touching again for over two months. What we are deliberately not doing here is inventing a fixed rupee price per refill, because it genuinely is not fixed - the oil cost depends on the intensity a clinic runs and the fragrance chosen, and those vary enough clinic to clinic that a single number quoted on a page like this would be more misleading than useful. The honest way to get an exact figure is a consultation, where the intensity and schedule you actually plan to run are used to price the refill properly. There is one part of this cluster where the fragrance cost is genuinely fixed and worth stating plainly: a single consultation cabin run on a SOSA Sukoon (₹1,899, a 500ml ultrasonic cool-mist diffuser) uses water-based fragrance from the Hotel Collection, priced from ₹299 for a 15ml bottle, with 100ml and 300ml sizes for a cabin used more heavily. That is the clearest, most forecastable refill line in this whole cluster, because the product and its fragrance are sold together with a stated starting price. Two things move a refill forecast in a clinic, and both are worth building into the plan rather than treating as surprises. Intensity: a machine run at the lowest usable setting, which is also the correct clinical-ambience choice since restraint reads as confidence in a medical space, uses fragrance more slowly than one run high. Hours: a machine timed to clinic hours only, using the 1h/4h/8h/24h app timers, uses less fragrance over a month than one left running around the clock. Both of these are settings a clinic controls directly, which means the refill forecast is not a fixed cost imposed on the clinic - it is one the clinic can tune. None of this changes the underlying honesty of the plan: fragrance is an ambience decision like lighting or seating, treatment and procedure rooms stay unscented and accrue no refill cost at all, and the clinician's judgement overrides any plan. Ask for a clinic scenting plan and we will turn your actual intensity and schedule into an exact refill forecast.
Forecast by cadence, not a flat rate. Vaayu's 400ml tank lasts up to 75 days, roughly 4-5 refills a year. A single cabin on a Sukoon runs on Hotel Collection fragrance from Rs 299 - the clearest single figure here.

How to forecast refills without guessing

Three points make up an honest refill forecast: the cadence, the two settings that move it, and the one figure in this range that is genuinely fixed.

1
Forecast the cadence first
Up to 75 days per Vaayu tank - roughly 4-5 refills a year
The 400ml tank in a SOSA Vaayu lasts up to about 75 days, depending on the intensity it runs at and how many hours a day it operates. For a reception on a typical ten-hour clinic schedule at a low intensity, that means the tank is refilled roughly four to five times a year. That frequency is what belongs in a practice diary - four or five dated refill reminders across the year - rather than a monthly rupee figure that will not match any single month, since a tank lasting over two months clearly is not being touched monthly.
Tip: put refill dates in the diary, not a monthly line on the budget.
SOSA Vaayu

2
Two settings that move the cadence
Intensity and run hours - both controlled by the clinic
A machine run at the lowest usable intensity - the correct choice for a clinic anyway, since restraint reads as confidence in a medical space - uses fragrance more slowly than one run high. And a machine timed to clinic hours only, using the 1h/4h/8h/24h app timers, uses less fragrance over a month than one left running continuously. Both of these are settings the clinic controls directly, which means the refill forecast is genuinely tunable rather than a fixed cost imposed from outside.
SOSA Vaayu
Adjustable intensity and app timers on the Vaayu are what let a clinic stretch or compress the refill cadence.

3
The one fixed figure in this range
A single cabin on a Sukoon and Hotel Collection fragrance, from Rs 299
Where the rest of this page is deliberately cautious about quoting a fixed rupee cost, this one figure is genuinely fixed and worth using directly. A single consultation cabin scented with a SOSA Sukoon (Rs 1,899) runs on water-based fragrance from the Hotel Collection, priced from Rs 299 for a 15ml bottle, with 100ml and 300ml sizes for heavier use. That is the clearest refill line in this entire cluster, because the product and its stated starting price are sold together.
Tip: for a single cabin, this is the one refill number worth budgeting directly.
SOSA Sukoon

The SOSA principle
A refill forecast built on frequency is honest. One built on a flat monthly rupee rate is a guess dressed up as a number.
Four to five diarised refill dates a year, at a low, honest intensity, is the plan most reception areas actually need.
SOSA Vaayu
The reception cadence: SOSA Vaayu, 400ml tank up to 75 days, roughly 4-5 refills a year on a normal schedule. ₹11,999.

The forecasting method, by machine

Here is the same forecast laid out by scenario, which is the version worth putting into an actual practice diary.

The SOSA plan
Refill forecasting, by setup

Roughly 4-5 tank refills a year. Exact oil cost confirmed on a consultation for your settings. View →

Treatment and procedure rooms
No refill cost at all - left unscented by default, so nothing to forecast there.

This forecasting method feeds directly into the wider number worked out in the monthly running cost of a scent machine in a skin clinic, and the full first-year picture in what it costs to scent a dermatology clinic in the first year. If a marketplace diffuser's refill economics are what prompted this question, why cheap marketplace diffusers end up costing a clinic more over time covers that comparison directly. The whole-clinic brief is what a premium dermatology clinic should smell like.

SOSA Vaayu
What moves it: Lower intensity and timed hours stretch the tank further - both settings the clinic controls directly.

A note from Sonal

This is the one cost question in this cluster where I will not hand over a single confident rupee figure, and I want to explain why rather than just say so. A refill cost genuinely depends on intensity and run hours, and quoting a flat number here would be tidier than it would be honest.

What I can give plainly is the cadence. The Vaayu's 400ml tank lasts up to about 75 days, so a reception on a normal ten-hour schedule at a low intensity refills roughly four to five times a year - put those dates in the practice diary and the forecast writes itself. For a single consultation cabin, the number is genuinely fixed: a Sukoon at ₹1,899 runs on Hotel Collection fragrance from ₹299, and that is the clearest single figure in the whole cluster.

The honesty that runs through every page here applies to forecasting too. We are not attaching a return to this number, and we make no claim that it affects bookings, retention or spend. Fragrance is an ambience decision, like lighting or seating. Treatment and procedure rooms stay unscented and cost nothing to refill, and the clinician's judgement overrides any scenting plan. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

Frequently asked questions

What do fragrance refills cost for a clinic diffuser?
It depends on the intensity you run and how many hours a day the machine operates, so forecast by frequency first: the SOSA Vaayu's 400ml tank lasts up to about 75 days, which is roughly four to five refills a year on a normal reception schedule. The exact oil cost per refill is confirmed on a consultation. For a single consultation cabin, a SOSA Sukoon runs on Hotel Collection fragrance from Rs 299, which is the clearest fixed figure in this range.
How often does a clinic diffuser need refilling?
For a SOSA Vaayu's 400ml tank on a typical ten-hour clinic day at a low intensity, up to about 75 days per fill, or roughly four to five refills a year. Higher intensity or longer daily run hours shorten that cycle, and a lower, honest intensity - the right choice for a clinic anyway - stretches it toward the longer end.
Why doesn't SOSA quote a single fixed refill price for the Vaayu?
Because it genuinely is not a fixed number - it depends on the intensity a clinic runs and the fragrance chosen, both of which vary clinic to clinic. Quoting one rupee figure for every clinic would be more misleading than useful, so the exact cost is confirmed on a consultation using your actual settings.
What is the clearest refill cost figure in this cluster?
A single consultation cabin on a SOSA Sukoon (Rs 1,899), which runs on water-based Hotel Collection fragrance priced from Rs 299 for a 15ml bottle, with 100ml and 300ml sizes for heavier use. That is fixed and stated on the product page, unlike the Vaayu's oil cost, which varies with intensity and hours.
Do treatment rooms add to a clinic's refill budget?
No. Treatment and procedure rooms are usually left unscented by default, so they accrue no refill cost at all. Forecasting can focus entirely on the public areas that are actually being scented.
SOSA Sukoon
The one fixed figure: SOSA Sukoon (₹1,899) for a single cabin, running on Hotel Collection fragrance from ₹299.
