The right way to estimate refill consumption is not to accept a made-up millilitres-per-day figure - it is to start from the one number that is actually verified and reason honestly from there.
Quick answers — read this first
How do developers estimate fragrance refill consumption for a gallery open 10 hours a day? Start from the one verified anchor and reason, rather than trusting a fabricated ml-per-day. A SOSA Vaayu (Rs 11,999) uses a 400ml tank that lasts up to about 75 days - and that figure moves with two things: how many hours a day the gallery runs the diffuser, and how large and open the space is. A ten-hour day in a big open hall consumes oil faster than a short day in a compact gallery, so a gallery running long hours should expect the tank to last toward the shorter end of that range, not the longest. Because the exact rate depends on your runtime and layout, the precise refill volume and reorder interval are set on a quotation rather than guessed. Made in India.
How long does a 400ml tank last in a busy gallery? Up to about 75 days, but a gallery running a full ten-hour day in a large open space will land toward the shorter end - it uses oil faster than a compact gallery on a short day. The exact interval is worked from your actual hours and area.
Can I get an exact millilitres-per-day figure? Not an honest fixed one - the consumption rate genuinely depends on your runtime, intensity and the size of the space. Rather than trust a made-up number, the precise refill volume is estimated from your gallery on a quotation.
The short answer
Short answer: estimate refill use from the verified anchor - a 400ml tank lasts up to about 75 days, moving with daily hours and area, so a 10-hour gallery lands toward the shorter end; the precise refill volume and reorder interval are set on a quotation, not a fabricated ml-per-day.
The range: a reed or spray is too passive for a busy gallery; the SOSA Vaayu (₹11,999) holds one even signature across a sales gallery or open floor up to ~2000-3000 sq ft on a timer; the Angaan (₹25,999) or Meenar for a large experience centre, clubhouse or lobby; one machine per zone or gallery.
Next step: shop the SOSA Vaayu, or send us the gallery or project - size, layout, ceiling height, footfall and how many galleries - and we will plan and quote it.
A luxury home is bought with emotion, and the sales gallery is where that emotion is manufactured. A buyer worth crores forms a judgement in the first minute - and the one thing almost every developer leaves to chance is what the space smells like. Designed well, scent turns a sales office into an experience: one clean, consistent signature that greets a buyer at the entrance, carries through the model area and the sample flat, and later follows the project into the finished lobby and clubhouse. The tool is an even, controllable cold-air diffuser - a SOSA Vaayu for a sales gallery or an open floor up to about 2000-3000 sq ft, on a timer so it holds all day with no staff spraying, and the larger Angaan or Meenar for a big experience centre, clubhouse or tower lobby. Reed diffusers and room sprays fade across a busy gallery and cannot hold a ten-hour day. And because one developer runs galleries, sample flats and lobbies across many projects, the real prize is a single scent identity, applied consistently and sized per space.
How do developers estimate fragrance refill consumption for a gallery open 10 hours a day?
Start from the one number that is actually verified, and reason honestly - do not accept a made-up millilitres-per-day. The verified anchor is this: a SOSA Vaayu (₹11,999) runs a 400ml tank that lasts up to about 75 days. The word doing the work is "up to". That figure moves with two variables: how many hours a day the gallery runs the diffuser, and how large and open the space is. A gallery open ten hours a day in a big open hall will use oil faster than a compact gallery on a short day - so a long-hours gallery should honestly expect the tank to last toward the shorter end of that range, not the full 75 days. That is the useful estimate: same anchor, adjusted down for heavy runtime. What you should not do is multiply a fabricated ml-per-day and print a false reorder schedule, because the real rate depends on your runtime, intensity and layout. Passive reeds are even harder to budget - they fade continuously and get replaced by feel. To turn the 75-day anchor into a precise refill volume and reorder interval for your gallery, a quick note with your hours and area returns a proper quotation.
A 400ml tank lasts up to about 75 days, less on a heavy ten-hour day in a big open hall - reason from that anchor and set the precise refill volume on a quotation.
Start from the space and the day. A sales gallery or open floor wants one even signature that holds for ten hours without staff spraying - that is the SOSA Vaayu (₹11,999, up to ~2000-3000 sq ft, on a timer). A large experience centre, clubhouse or tower lobby steps up to the Angaan (₹25,999) or Meenar; one machine per zone. A passive reed diffuser or room spray fades across a busy gallery.
Active cold-air machine that fills a genuinely large open floor up to about 1000m3 (roughly 2000-3000 sq ft) evenly, with Bluetooth app & 1h/4h/8h/24h timers; ships with four hotel-inspired oils. Made in India.
Estimating refills honestly means holding one anchor and adjusting it for two variables - never inventing a fixed daily rate.
1
One verified anchor
400ml, up to ~75 days
The only honest starting point is the tank life: 400ml lasts up to about 75 days. Everything else is an adjustment to that anchor, not a separate invented number. Oils start from Rs 299.
Tip: the anchor is a 400ml tank lasting up to about 75 days - reason from it, do not replace it.
2
Adjust for hours and area
Heavy runtime, shorter life
A ten-hour day in a large open hall uses oil faster than a short day in a compact gallery, so a busy gallery lands toward the shorter end of the range. The estimate is the anchor, dialled for your runtime.
3
Precise volume on a quotation
Estimated, not fabricated
Because the rate depends on your hours, intensity and layout, the exact refill volume and reorder interval are worked from your gallery - never a made-up ml-per-day printed as fact.
Tip: the precise refill volume is estimated from your gallery on a quotation, not fabricated.
The SOSA principle
A supplier who hands you a confident millilitres-per-day figure without asking your opening hours is not being precise - they are being made up.
An honest range you can plan around beats a false exact number that collapses the moment your gallery runs longer than the spreadsheet assumed.
Worth knowing: SOSA Safar Waterless Cordless Diffuser - Compact, cordless, rechargeable cold-diffusion for a small or personal space - a bathroom, dressing room, study or bedside; up to 10 hours continuous (30 intermittent) per charge, 3 speed settings and a 1h/2h/3h timer, ships with three hotel-inspired oils, from ₹3,999.
Budgeting refills is two decisions - one signature that fits the brand, and a refill estimate reasoned from the anchor - and the second is what a quotation makes precise.
The SOSA scent edit
Estimating refill consumption
Scent
Why it suits the mood
A fabricated ml-per-day figure
Collapses on contact with reality - the real rate depends on your hours, intensity and layout, so a fixed daily number is a guess printed as a fact.
Replacing reeds by feel
Impossible to budget - passive reeds fade continuously and get swapped when someone notices, so consumption is never predictable.
Reasoned from the 75-day anchor
A 400ml tank up to about 75 days, adjusted down for a heavy ten-hour day, made precise on a quotation - an honest estimate you can actually plan around.
The Vaayu (₹11,999) runs a 400ml tank lasting up to about 75 days, less on a long ten-hour day in a big open hall; the hotel-inspired oils (from ₹299) are the refill itself. A larger or multi-zone gallery runs one machine per zone, each with its own tank, and a grand experience centre steps up to the Angaan (₹25,999). The precise refill volume, reorder interval and any multi-gallery total are worked from your hours and area on a quotation.
Also worth a look: SOSA Hotel Collection Fragrance - The signature scent itself - hotel-inspired oil, from ₹299, from ₹299.
One SOSA Vaayu (₹11,999) holds an even signature scent across a sales gallery or open floor up to ~2000-3000 sq ft, on a timer, all day; a large experience centre, clubhouse or lobby steps up to the Angaan, one machine per zone - sized by the volume of air, not floor area alone.
Estimate from the anchor, adjust for the hours, and price it on a quotation - that is how you budget refills honestly, without a single made-up number.

Our pick for this room: SOSA Vaayu Waterless Cold-Air Diffuser - Active cold-air machine that fills a genuinely large open floor up to about 1000m3 (roughly 2000-3000 sq ft) evenly, with Bluetooth app & 1h/4h/8h/24h timers; ships with four hotel-inspired oils, from ₹11,999.
Every SOSA system here is made in India and sized to a real volume of air. A reed or room spray is too passive for a busy gallery; the Vaayu holds one even signature across a sales gallery or open floor up to ~2000-3000 sq ft on a timer; and the Angaan or Meenar handle a large experience centre, clubhouse or tower lobby - one machine per zone or gallery. Across multiple projects, the aim is one consistent scent identity, sized per space; bespoke multi-gallery quantities and running cost are best planned on a quotation. Here is the full range.
The SOSA scenting range for developers
From a closing cabin to a grand experience centre - matched to the volume of air, the footfall and the project brand, one consistent identity across galleries
The largest interiors - grand lobbies, double-height experience centres, clubhouses (~12,000-18,000 sq ft)
Commercial HVAC scenting for the biggest volumes
₹38,500
How to plan it honestly: a reed diffuser or a room spray is passive or short-lived - fine on a single desk, but it fades across a busy gallery and cannot hold a ten-hour day. For a sales gallery, sample flat or open floor, one even signature held all day on a timer is the job of the SOSA Vaayu (one open floor up to about 2000-3000 sq ft), and a large or multi-level experience centre runs one machine per zone or floor - scent does not travel up a staircase on its own. A large experience centre, clubhouse or tower lobby steps up to the Angaan or Meenar. Three developer notes. Size by the volume of air (length x width x ceiling height), not floor area - a double-height lobby behaves far larger. Choose the scent family to fit the project brand - nature-led, urban, quiet-luxury or resort. And on running cost and multiple galleries: the honest anchors are the machine price (Rs 11,999) and that a 400ml tank lasts up to about 75 days depending on intensity and daily hours; a precise monthly figure, refill volume, and multi-gallery quantities depend on your hours, area and how many spaces, so those are planned on a quotation rather than guessed. A scent enhances a clean, well-ventilated space; it does not mask a musty or closed-up smell, and SOSA makes no medical or air-purification claims, and does not on its own increase sales or conversions.

A note from Sonal
I work with a lot of developers, and the story is almost always the same: the sales gallery cost a fortune and looks the part, and yet it still smells like a corporate office. Buyers are about to make one of the largest emotional decisions of their lives, and we design meticulously for the marble, the lighting and the model - and then leave to chance the one sense most tied to memory and feeling. A gallery you can smell is a gallery buyers remember, and the emotion you build in that first minute is the emotion they carry into the closing room.
My advice is to design one signature scent for the whole buyer journey rather than a nice smell in one room - present at the entrance, carried through the model area and the sample flat, chosen to fit the project brand (nature-led, urban, quiet-luxury or resort). One Vaayu holds it evenly across a sales gallery of up to about 2000-3000 sq ft, on a timer, for the full ten-hour day, with no staff spraying anything. A large experience centre, clubhouse or tower lobby steps up to the Angaan or Meenar, one machine per zone.
The bigger opportunity is that one developer runs galleries, sample flats, lobbies and clubhouses across many projects - so the same signature, applied consistently and sized per space, becomes part of the brand, and can follow a project from launch gallery all the way to the finished tower. I will always be honest about what scent does and does not do: it makes a space feel considered and memorable, but it does not on its own increase sales. Everything is alcohol-free and made in India; SOSA makes no medical or air-purification claims and is independent of any hotel we reference. Send me the gallery or the project - size, ceiling height, footfall, hours and how many spaces - and I will plan, size and quote it properly.
Frequently asked questions
How do I estimate refill consumption for a busy gallery?
Start from the anchor - a 400ml tank lasts up to about 75 days - and adjust down for a heavy ten-hour day in a large open space, which uses oil faster. The precise refill volume is then set on a quotation, not a fabricated ml-per-day.
How long does a 400ml tank last on a 10-hour day?
Toward the shorter end of the up-to-75-day range - a full ten-hour day in a big open hall uses oil faster than a short day in a compact gallery. The exact interval is worked from your actual hours and area.
Can you give me an exact ml-per-day figure?
Not an honest fixed one - consumption genuinely depends on your runtime, intensity and the size of the space. Rather than a made-up number, the precise refill volume is estimated from your gallery on a quotation.
Is scenting easier to budget than reeds?
Yes - a diffuser tank has a clear anchor (400ml, up to about 75 days) you can reason from, whereas passive reeds fade continuously and get replaced by feel, so their consumption is never predictable.
How do I plan refills across several galleries?
Each gallery runs its own machine and tank, so the refill estimate scales with the number of galleries and their hours. A quotation works the per-gallery volume and a portfolio total from your actual runtimes.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the scenting advice applies to any brand.
Facts verified August 2026 (SOSA product pages): The SOSA Safar is a compact, cordless, rechargeable waterless cold-diffusion perfume diffuser priced at ₹3,999, described for use in a car, on a desk, in a handbag or a hotel room; it runs up to about 10 hours continuously or 30 hours intermittently on a single charge, has 3 speed settings and a 1h/2h/3h auto-off timer, and ships with three SOSA Hotel Collection hotel-inspired oils. It is a personal-space device for strong close-range projection and is not rated to fill a large open floor evenly. The SOSA Vaayu is a waterless cold-air diffuser priced at ₹11,999 that atomises alcohol-free, water-free fragrance oil into a dry nano-mist covering up to 1000m3 (about 2000 to 3000 sq ft) per open floor, with a 400ml tank (four 100ml oils included) 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; a very large or double-height floor may need the larger Angaan (₹25,999, ~8,000-10,000 sq ft) or Meenar (₹38,500, ~12,000-18,000 sq ft), and a multi-storey home generally needs one machine per floor. A reed diffuser (from about ₹749) is passive and cannot be adjusted in strength. Fragrance projection depends on the volume of air and on ventilation - a closed, air-conditioned room holds scent while open windows, balconies and fast fans disperse it - so the same floor area can need different power. A signature scent enhances a clean, well-ventilated room; it does not remove a musty or closed-up smell, which should be aired out first, 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.
