Is 75 days the guaranteed life of a 400 ml tank? It is the upper end of the range, not a guarantee for every setup. A 400ml tank lasts up to about 75 days at moderate store settings; higher intensity or longer daily hours shorten it. Think of 75 days as the best-case, store-hours figure and adjust down for heavier use.
How often will I refill a 400 ml tank? Occasionally, not constantly. Because 400ml lasts up to about 75 days at moderate settings, many businesses refill roughly every two to two and a half months at typical store hours, depending on their settings. Higher intensity or 24-hour running brings refills forward.

Facts verified August 2026 (SOSA Vaayu product page): The Vaayu is a waterless cold-air diffuser priced at ₹11,999 (one-time), 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), has a 400ml refillable tank that lasts up to about 75 days depending on the intensity setting and daily run hours, offers 1h/4h/8h/24h timers and Bluetooth app control, and runs under 38dB. The main recurring cost is fragrance oil; electricity is minimal on a low-power cold-air atomiser. SOSA does NOT publish a fixed monthly running-cost figure because it depends on intensity, hours, space and refill size chosen - the exact monthly cost, refill cadence, refill sizes and prices, bulk machine pricing, lead times and any multi-location fragrance-supply plan are confirmed on a quotation, and there is no compulsory subscription or lock-in. Larger spaces use the Angaan (₹25,999, ~8,000-10,000 sq ft) or Meenar (₹38,500, ~12,000-18,000 sq ft). A signature scent enhances a premium space and works alongside good service; SOSA makes no claim that scent alone increases sales, conversions or footfall. Hotel-inspired scents are SOSA's own original interpretations; SOSA is independent and not affiliated with any hotel. Prices and availability are subject to change - see the live product pages.
This is the one running-cost figure I can give you straight from the product page: a 400 ml tank lasts up to about 75 days - and once you see what moves that number, you can predict your own refill rhythm with confidence.

Straight answer
How long does a 400 ml tank of fragrance last?
This is the running-cost figure I can give you directly. For the SOSA Vaayu, a 400ml tank lasts up to about 75 days, depending on the intensity setting and how many hours a day it runs. At a moderate store-hours setting it sits toward the top of that range; at full intensity all day it lasts less. In practical terms that is roughly a tank every two to two and a half months at typical store hours, depending on your settings - so fragrance is an occasional refill rather than a constant spend. The best part for budgeting is that the machine ships with 400ml of oil included, so your first tank is already covered by the one-time ₹11,999 price. Your exact tank life depends on how you run it, and the precise figure and refill cadence for your setup are confirmed on a quotation.
A 400ml tank lasts up to about 75 days depending on intensity and hours - roughly a tank every 2 to 2.5 months at typical store hours - and the first tank ships included with the Rs 11,999 machine.
The honest headline: the SOSA Vaayu is ₹11,999 as a one-time machine, and it ships with 400ml of oil (about one full tank), so your first fill is included. After that the main recurring cost is fragrance oil - a 400ml tank lasts up to about 75 days depending on intensity and hours - plus minimal electricity. For exact monthly figures, bulk pricing or a multi-location plan, a quotation gives you real numbers.

What determines how long a 400 ml tank lasts
The up-to-75-days figure is real, but it is a range for a reason - here is what pushes it toward the top or the bottom.
1
Intensity setting
The main lever on tank life
Intensity is the biggest driver. A moderate setting sips through 400ml and pushes tank life toward the 75-day top of the range; a high setting pours more mist and shortens it. Choosing the lowest setting that scents the space well is the simplest way to make a tank last.
Tip: a moderate intensity pushes a 400ml tank toward the top of its up-to-75-day range.
2
Daily hours
How long it runs each day
A tank on 8 store hours a day lasts longer than one running 24 hours. The Vaayu's 1h/4h/8h/24h timer sets exactly how long the machine runs, which directly sets how many days a 400ml tank covers.
3
Space and placement
How hard the tank works
A larger or more open space needs more output to scent evenly, using the tank faster, while good placement in moving air lets a moderate setting do the job. Both move where you land in the up-to-75-day range.
Tip: a bigger, more open floor uses a 400ml tank faster than a small enclosed room.
The SOSA principle
The 400ml-up-to-75-days figure is the one number in commercial scenting I can hand you cleanly - and once you know intensity and hours move it, you can dial your own tank life up or down at will.
Moderate setting on store hours puts you near 75 days; high intensity all day brings it in.
Turning up-to-75-days into a refill rhythm
Here is how the up-to-75-days figure translates into a refill rhythm you can actually plan around.
The SOSA scent edit
What a 400 ml tank's life looks like
| Scent | Why it suits the mood |
|---|---|
| Moderate setting, store hours | Toward the top of the range - up to about 75 days, roughly a tank every two to two and a half months, depending on your settings. |
| Higher intensity or 24-hour running | Toward the lower end - the tank empties sooner and refills come forward; exact figures on a quotation. |
| First tank included | The machine ships with 400ml of oil, so your first up-to-75-days is already covered by the one-time Rs 11,999 price. |
The neatest way to nail your own rhythm is to run the included 400ml at your chosen settings and note when it needs topping up - that becomes your refill cadence. If you would rather have it planned, a quotation matches refill size and timing to your intensity, hours and space. For a very large or multi-floor space, the Angaan (₹25,999) or Meenar (₹38,500) hold and use fragrance suited to that scale.
Clear numbers, no surprises

A 400ml tank lasting up to about 75 days is the figure I am happiest giving, because it is real and it is generous - it turns fragrance from a worry into an occasional, predictable refill.

How to read this: the biggest number is a one-time machine (₹11,999), and it ships with 400ml of oil, so your first tank is included. After that the main recurring cost is fragrance oil, and because a 400ml fill lasts up to about 75 days (depending on the intensity setting and daily hours), refills are occasional. We do not publish a fixed monthly rupee figure because it genuinely depends on your intensity, hours, space and the refill size you choose - so the exact running cost, bulk machine pricing, refill cadence and any multi-location supply are confirmed on a quotation. There is no compulsory subscription or lock-in beyond buying the fragrance you use.

A note from Sonal
When a business asks me what commercial scenting really costs, I give them the honest shape of it rather than a headline number. There is a one-time machine - the Vaayu is ₹11,999 and it ships with 400ml of our oil, so the first tank is included. After that, the main recurring cost is simply the fragrance oil you use, and electricity is minimal.
The reason I will not quote a fixed monthly figure blindly is that it honestly depends on how you run it. A 400ml tank lasts up to about 75 days depending on the intensity you choose and how many hours a day it runs - a store on daytime hours at a moderate setting sips through it slowly, a high-intensity all-day setting uses more. That is exactly why we put it on a quotation: we look at your space, your hours and your locations, and the numbers are real rather than a guess.
For bulk orders and multi-location groups, we plan the machine quantity, placement and monthly fragrance supply together, so procurement can budget it properly with no surprises. Everything is made in India, and I would always rather you trial the fragrance first and buy what fits than sign up to something you have not smelled.
Frequently asked questions
How long does a 400 ml tank of fragrance last?
For a SOSA Vaayu, up to about 75 days depending on the intensity setting and daily hours - roughly a tank every two to two and a half months at typical store hours, depending on your settings. Moderate store settings sit near the top of that range; heavier use shortens it. The exact life for your setup is confirmed on a quotation.
Is 75 days guaranteed?
No - it is the upper, best-case end of the range at moderate store settings. Higher intensity or longer daily hours bring the life down. Treat 75 days as the store-hours figure and adjust for heavier use.
Does the machine come with a 400 ml tank of fragrance?
Yes. Each Vaayu ships with four SOSA Hotel Collection oils of 100ml each - 400ml total, about one full tank - so your first up-to-75-days is included in the one-time Rs 11,999 price.
How do I make a 400 ml tank last longer?
Run a moderate intensity rather than full, use the timer to run only during business hours, and place the machine well so a lower setting scents the space evenly. These push tank life toward the top of the up-to-75-day range.
How do I get my exact tank life?
Request a quotation with your intensity, daily hours and space size, or simply run the included 400ml and note the rate. SOSA gives an honest figure and refill cadence matched to how you run the machine.
