How many scent machines does a 900 sq ft clinic branch need compared to a 4,500 sq ft one? A 900 sq ft branch and a 2,500 sq ft branch both typically need one SOSA Vaayu, since it covers up to about 3,000 sq ft, but at different intensity bands. A 4,500 sq ft branch, or one split across two floors, usually needs two Vaayu units running the same fragrance.
At what size does a clinic branch need an Angaan instead of a Vaayu? Roughly once a single branch is a genuinely large, multi-department building of 8,000 to 10,000 sq ft on one central HVAC loop. Below that, one or two SOSA Vaayu units, sized to the branch's actual footprint and ceiling height, are the honest answer.

Facts verified 24 August 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 a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, and also runs standalone wall-mounted or lay-flat. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. 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. Prices and availability are subject to change - see the live product pages.
A chain with branches ranging from 900 to 8,000 square feet can absolutely run one fragrance across all of them - the part that must change with the footprint is never the scent, it is the machine count and the intensity band.
Quick answers — read this first
Can the same fragrance work in clinics of different sizes? Yes. The fragrance itself does not need to change with square footage. What changes is the machine count and the intensity band: a smaller branch needs one SOSA Vaayu (₹11,999, up to 1000m³) at a lower setting, while a larger branch needs a higher band, a second Vaayu, or a SOSA Angaan (₹25,999) on the HVAC.How many scent machines does a 900 sq ft clinic branch need compared to a 4,500 sq ft one? A 900 sq ft branch and a 2,500 sq ft branch both typically need one SOSA Vaayu, since it covers up to about 3,000 sq ft, but at different intensity bands. A 4,500 sq ft branch, or one split across two floors, usually needs two Vaayu units running the same fragrance.
At what size does a clinic branch need an Angaan instead of a Vaayu? Roughly once a single branch is a genuinely large, multi-department building of 8,000 to 10,000 sq ft on one central HVAC loop. Below that, one or two SOSA Vaayu units, sized to the branch's actual footprint and ceiling height, are the honest answer.
The short answer
Short answer: yes, one fragrance can run across every branch regardless of footprint; only the machine count and intensity band need to change, based on each branch's air volume - a SOSA Vaayu (₹11,999, up to 1000m³) for most branches, two for a larger or split-level one, and a SOSA Angaan (₹25,999) for a genuinely large flagship branch.
The pick: one or two SOSA Vaayu (₹11,999 each) sized to a branch's footprint, stepping up to the SOSA Angaan (₹25,999) only for a genuinely large branch on one HVAC loop.

Straight answer
Can the same fragrance work across clinic branches of very different sizes?
Yes, and it should - the fragrance is the one thing that must not change across footprints, because that is what makes the chain recognisable. What genuinely changes is sizing, and it follows air volume, not floor area alone. One SOSA Vaayu (₹11,999) is rated to 1000m³, roughly 2,000 to 3,000 sq ft at a normal ceiling height, so a 900 sq ft branch and a 2,500 sq ft branch both typically run one machine, at different intensity bands to account for the smaller branch's lower air exchange. A 4,500 sq ft branch, or one split across two floors, generally needs two Vaayu units on the same fragrance. Once a single branch reaches roughly 8,000 to 10,000 sq ft as a multi-department building on one central HVAC loop, the honest answer stops being more small machines and becomes a SOSA Angaan (₹25,999) on the duct. Remember that a polyclinic's genuinely scentable area is usually far smaller than its total footprint, since consultation, treatment, diagnostics and paediatric rooms stay fragrance-free regardless of the building's size - so size the machine to the scented zone, not the whole floor plate. No claim is made that a larger, better-scented branch performs better commercially; the benefit is a recognisably consistent chain. A portion of every order supports girl-child education through Nanhi Kali.
The fragrance never changes with square footage. The machine count and intensity band do, sized to each branch's actual scentable air volume.
Most branches, regardless of exact size, run one or two SOSA Vaayu units - waterless, under 38dB, each rated to 1000m³ - on the same chain fragrance. A genuinely large flagship branch on one HVAC loop steps up to the Angaan instead.

Sized by footprint
The fragrance holds constant; the count follows the square footage
The two machines that scale across different branch sizes
Every branch, whatever its footprint, chooses between the same two machines. What changes is how many and at what setting, never the fragrance.
A smaller branch, under about 2,500 sq ft
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft. One machine at a lower intensity band typically covers a smaller, more sealed branch.
From ₹11,999
A mid-size or split-level branch
SOSA Vaayu (second unit)
A branch of 3,000-6,000 sq ft, or one split across two levels, typically needs a second Vaayu on the same fragrance rather than one machine pushed past its honest coverage.
From ₹11,999
A large flagship branch on one HVAC loop
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, with an 800ml reservoir, metal body, programmable schedules and under 42dB running. The honest answer once a branch is genuinely large.
From ₹25,999
Yes to the fragrance, no to a single machine count or setting
Three checks decide the machine count for any branch: its air volume, not just its floor area; how much of that footprint is actually scentable; and whether ceiling height quietly changes the number.
1
Volume, not floor area, sets the count
Length times width times height, in cubic metres
Two branches with the same floor area but different ceiling heights are not the same sizing problem. A double-height reception in a flagship branch holds far more air than a standard-height reception of the same square footage, and that is where floor-area rules of thumb quietly fail a chain trying to size branches consistently.
Tip: always convert to cubic metres before comparing two branches' sizes.
The Vaayu is rated to 1000m³, which does most of the sizing arithmetic for a typical branch on its own.
See SOSA Vaayu →
2
Size the scentable zone, not the building
Most of any branch, at any size, is never scented
Consultation rooms, treatment rooms, diagnostics and any room a patient lies down in stay fragrance-free at every branch, regardless of that branch's total square footage. A 10,000 sq ft branch may have only 1,200-2,000 sq ft of genuinely scentable public area, so size the machine count to that, not to the lease.
Where the scentable zone itself is large and shares one HVAC loop, an Angaan covers it evenly instead of adding more small machines.
See SOSA Angaan →
3
Let the intensity band do the fine-tuning
Two branches at the same square footage can still need different bands
Square footage gets you to the right machine count. It does not tell you the exact setting, because a sealed branch and a branch with a street-facing door at the same footprint still exchange air at different rates. Set the final intensity on-site, against the perceived level, not from the floor plan alone.
Tip: square footage picks the machine count; the room itself picks the setting.
The Vaayu's adjustable intensity is what lets one machine model fit branches that are nominally the same size but behave differently.
See SOSA Vaayu →
The SOSA principle
Different square footages are a sizing problem, never a fragrance problem. The scent that suits a 900 sq ft branch suits an 8,000 sq ft one just as well.
What changes with size is how many machines you place and how high you set them, not what is in the tank.
One fragrance, sized differently by square footage
One table converts almost any branch's footprint into a machine count. The fragrance in the right-hand column never changes.

If your branches also run different HVAC systems at similar footprints, standardising fragrance intensity when every branch has different HVAC covers the air-exchange side of this sizing question in more depth. Once you have the count settled across branches, building a full scent SOP for a multi-location business is where to write the per-branch bands down. The pillar guide, what a premium multi-speciality polyclinic should smell like, covers the fragrance direction itself.

A note from Sonal
A chain operator once sent me floor plans for three branches - 900, 2,500 and 4,500 square feet - and asked whether they could all run the same fragrance. Yes, without hesitation. What cannot be the same is the machine count and the setting, because those follow the volume of air in the room, not the brand.
The maths is simple once you do it by volume rather than guesswork: one SOSA Vaayu (₹11,999) is rated to 1000m³, roughly 2,000 to 3,000 sq ft at a normal ceiling height, so a 900 sq ft branch and a 2,500 sq ft branch both need one machine, just at different intensity bands, while a 4,500 sq ft branch or one split across two floors needs two. Past about 8,000 sq ft on one central HVAC loop, stop counting small machines and specify a SOSA Angaan (₹25,999) on the duct instead. The fragrance itself never changes across any of these footprints - only the count and the band do.
What I will not tell a chain is that a bigger footprint needs a stronger fragrance, or that getting this right will move footfall or revenue - neither is true. The honest benefit is that a patient walking from a 900 sq ft branch into a 4,500 sq ft one recognises the same considered place. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Can one fragrance work across clinic branches of very different sizes?
Yes. The fragrance itself does not need to vary with square footage. What should vary is the number of machines and the intensity setting, sized to each branch's own air volume.
How many scent machines does a small branch need compared to a large one?
A branch under about 2,500-3,000 sq ft at a normal ceiling height typically needs one SOSA Vaayu (Rs 11,999). A branch of 3,000-6,000 sq ft, or one split across two levels, typically needs two. A genuinely large branch of 8,000-10,000 sq ft on one HVAC loop needs one SOSA Angaan (Rs 25,999) instead.
Does a bigger branch need a stronger fragrance?
No. A bigger branch needs more machines, or one HVAC-connected machine, sized to its air volume - not a more concentrated scent. The fragrance itself stays the same across every branch size.
What percentage of a large branch is actually scented?
Often much less than the total footprint. Consultation, treatment, diagnostic and any room a patient lies down in stay fragrance-free at any branch size, so a 10,000 sq ft branch may have only 1,200-2,000 sq ft that is genuinely scented.
Should ceiling height be considered when sizing a branch's scent machines?
Yes. Sizing should be based on cubic metres, not floor area alone, because a double-height reception holds far more air than a standard-height room of the same square footage and can quietly need an extra machine or a higher intensity band.
