How much oil comes with a SOSA Vaayu? Each Vaayu comes with four 100ml waterless oils, which fill its 400ml tank once. On typical home scheduling that lasts about a year, but all-day commercial use at higher intensity uses oil faster, so track the tank for the first weeks.
What do SOSA Vaayu refills cost? Single-scent waterless refills are Rs 1,049 for 100g and Rs 1,849 for 300g; hotel-inspired blends are Rs 1,099 and Rs 1,899. Ten 300g single-scent refills are 10 x Rs 1,849 = Rs 18,490 at list price.

Vastu note: Vastu Shastra is a traditional Indian system of design and orientation. SOSA respects it as a cultural and personal preference. The placement advice here is practical - airflow, power access, safety and guest comfort - and SOSA makes no claim that any fragrance or machine placement brings prosperity, luck, footfall or business success.
Comfort note: Fragrance is a preference, not a treatment. Keep intensity low where children, older guests or fragrance-sensitive visitors are present, ventilate well, and keep machines and oils away from open flames, diyas and incense.
Facts verified on the SOSA store, October 2026: SOSA Vaayu is a waterless cold-air scent machine covering up to 1000m³ (about 2,000-3,000 sq ft, one whole floor), with a 400ml refillable tank and four 100ml waterless oils in the box; ₹12,499 with the SOSA Originals set or ₹12,999 with a hotel-inspired set.

How do I estimate the first-year fragrance refill requirements for ten franchise stores operating different hours?
Finance wants one number for the year's fragrance refills, across ten stores that open at different times and close at different times. Any supplier who gives you that number before a single store has run is guessing - including us. Consumption depends on hours, intensity, room size and doors, and those differ in every store. What you can do is measure it properly in a few stores first and project from real readings. Here is that method, step by step.
Quick answers — read this first
How do I estimate fragrance refill needs for ten stores? Use pilot-and-project. Run two or three representative stores (short and long hours) for about a month at the intensity in your spec, record how much the tank drops against the scheduled run hours, then scale that to each store's own schedule for the year. Add a buffer and reorder per store. There is no reliable published consumption rate for commercial use.How much oil comes with a SOSA Vaayu?

The short answer
Short answer: do not budget from a guessed rate: pilot two or three representative stores for a month at spec intensity, record the tank drop against scheduled run hours, scale to each store's schedule, add a buffer, and reorder per store; refills Rs 1,049 / Rs 1,849.

Straight answer
How do I estimate first-year fragrance refill needs for ten franchise stores that run different hours?
Measure first, then project - do not budget a year from a guess. There is no honest published consumption figure for commercial use: SOSA's own guidance is that the oils in the box last about a year on typical home scheduling, and that all-day commercial use at higher intensity uses oil faster. So use pilot-and-project. 1. Pick pilots: two or three stores that represent your range - one short-hours, one long-hours, ideally one small and one large. 2. Run the spec: for about a month, at the intensity band and schedule in your franchise standard, with key-lock on so nobody changes it. 3. Record: mark the tank level at the start and every week, and note the scheduled run hours from the Vaayu app. 4. Project: for each of the ten stores, scale the pilot's usage by that store's own scheduled hours (and adjust for a store set higher or lower in the band). 5. Buffer: add a margin for festive hours, longer weekends and the stores you could not pilot. 6. Reorder per store, not once for the chain. Prices to plug in: single-scent refills ₹1,049 (100g) or ₹1,849 (300g); hotel-inspired blends ₹1,099 / ₹1,899. Each machine's box oils are your first 400ml. Ask SOSA whether volume pricing applies to refills for a chain. A portion of every order supports girl-child education through Nanhi Kali.
One line: pilot two or three stores for a month, read the tanks against scheduled hours, scale to each store's schedule, add a buffer. No guessed rates. Refills from Rs 1,049.
For one consistent scent across a shop or office floor, start with SOSA Vaayu at ₹12,499 (four 100ml oils in the box), and keep a 300g refill (₹1,849) in the stockroom for launch week.

The pilot-and-project method
The method is simple arithmetic on real readings. The discipline is in keeping the pilot stores at the spec settings long enough for the numbers to mean something.
1
Choose representative pilots
Short hours, long hours, small and large
Ten stores rarely behave alike, so pilot the extremes rather than the average. A store open late every day and a store on short hours give you the range; a small unit and a large one show how room size moves the intensity setting. Run each pilot at the intensity band and schedule written in your standard, with the Vaayu key-lock on - if a manager turns it up halfway through, the reading is no longer useful. About a month gives you weekly readings across normal and busy days.
Tip: pilot the extremes at spec settings, key-lock on, for about a month.
2
Record the right numbers
Tank drop against scheduled run hours
Each week, note the tank level and the scheduled run hours from the app's 1h/4h/8h/24h timers and day settings, plus the intensity used. Divide the drop by the run hours for that store's own usage per run hour. Do the same for each pilot; they will differ, which is the point. Note anything unusual - a festival week, a door propped open, AC servicing. Refills are sold by weight (100g, 300g) while the tank is read in ml, so the simplest cross-check is to count how many refills each pilot actually pours.
3
Project, buffer, reorder
Scale each store, then add margin
For each store, multiply the closest pilot's usage per run hour by that store's scheduled run hours for the year. Adjust up or down if the store runs higher or lower in the intensity band. Add a buffer for festive extended hours and for any store you could not pilot. Convert to refills - single scents ₹1,049 / ₹1,849, hotel-inspired blends ₹1,099 / ₹1,899 - and plan reorders store by store, with a spare 300g refill always on the shelf. Re-check the projection after the first quarter against actual orders.
Tip: project per store from real readings, add a buffer, and re-check after the first quarter.
The SOSA principle
The only honest first-year refill number is one your own stores produced. Pilot, read the tanks, project per store - and treat any figure given before that as a guess.
Box oils = the first 400ml tank per machine. Refills: Rs 1,049 / Rs 1,849 (single scents), Rs 1,099 / Rs 1,899 (hotel-inspired). One 300g spare per store = 10 x Rs 1,849 = Rs 18,490 at list price.
Turning pilot readings into a refill plan
Here is how the method breaks down from pilot to purchase order.
The SOSA scent edit
First-year refills for ten stores: the pilot-and-project steps
| Scent | Why it suits the mood |
|---|---|
| Pilot · two or three representative stores | About a month at spec intensity and schedule, key-lock on, short-hours and long-hours stores included. |
| Record · weekly tank readings | Tank level, scheduled run hours and intensity setting; count refills poured as a cross-check. |
| Project · per store | Pilot usage per run hour x each store's own scheduled hours for the year, adjusted for its intensity. |
| Buffer and reorder · store by store | Margin for festive hours and unpiloted stores; one 300g spare (Rs 1,849) per store on the shelf. |
For the earlier budgeting step, see how many machines to budget across stores of different sizes, and for purchasing, planning bulk fragrance purchases for different operating schedules. See the waterless refills or contact SOSA about chain refill pricing.

The SOSA scenting ladder
Size the machine to the space you actually want scented. One Vaayu scents the floor it sits on; rooms you keep closed - cabins, trial rooms, washrooms - are better served by a reed diffuser or a small machine of their own. A portion of every order supports girl-child education through Nanhi Kali.

A note from Sonal
Many of the business owners who message us are weeks away from opening. The interiors are nearly done, the signage is ordered, the AC is going in - and fragrance is the one thing nobody planned. I would much rather we plan it together now, while the electrician can still put a socket in the right place.
Many of you also plan around Vastu - a north- or east-facing entrance, the northeast kept for the pooja. I respect that, and we will work around it. But I will be honest with you: a fragrance does not bring prosperity, and no machine placement can promise footfall. What a scent can do is make your space feel cared for from the first step inside. When the Vastu-preferred corner and the practical corner disagree, I would choose the spot where the air moves, the plug is safe and nobody can knock the machine over.
Send us your floor plan before you buy. If one SOSA Vaayu is right, we will say so; if two reed diffusers would do, we will tell you that too.
Frequently asked questions
How long does one SOSA Vaayu tank last in a store?
It depends on hours and intensity. The four 100ml oils in the box fill the 400ml tank once and last about a year on typical home scheduling; all-day commercial use at higher intensity uses oil faster. Track the tank for the first weeks in your own store.
Why not just use an average consumption figure?
Because none is published for commercial use, and stores differ in hours, size, doors and intensity. A figure that suits one store can be badly wrong for another. Two or three pilot stores give you real readings to project from.
How many stores should I pilot?
Two or three that represent your range: a short-hours and a long-hours store, ideally one small and one large. Run them for about a month at the settings in your franchise standard with the key-lock on.
How should refills be ordered across ten stores?
Store by store, from each store's projection, with one 300g spare (Rs 1,849) kept on the shelf. Reorder when a store opens its spare. Ask SOSA whether volume pricing applies to refills for a chain; nothing is published.
Do hotel-inspired refills cost more?
Slightly. Single-scent waterless refills are Rs 1,049 (100g) and Rs 1,849 (300g); hotel-inspired blends are Rs 1,099 and Rs 1,899. Hotel names describe styles only; SOSA is independent and not affiliated with any hotel.
