What should a franchise fragrance clause mandate versus leave to the franchisee? Mandate the fragrance itself, the machine model, the zoning rule, and the turn-it-down-on-complaint standard. Leave the intensity band to the franchisee, since only they can judge their own building's air volume and HVAC correctly on-site.
Can a franchisor remotely check a franchisee's scent machine settings? No. The SOSA Vaayu's app is Bluetooth and on-site only, so there is no remote reading a franchisor can pull from head office. Auditing intensity requires a physical walk-through by someone who has been out of the location for at least ten minutes.

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 franchisor's instinct is to mandate everything for fairness, including the exact intensity number. That is the one thing a franchise fragrance standard should not mandate, because only the franchisee standing in their own building can set it correctly.
Quick answers — read this first
Should every franchise clinic use the same scent machine and fragrance? Yes to the machine standard and the fragrance - both should be mandated in the franchise operations manual with no local substitutes, using a SOSA Vaayu (₹11,999) as the default. The intensity setting should not be mandated to one number; it should be set locally to each location's own building.What should a franchise fragrance clause mandate versus leave to the franchisee? Mandate the fragrance itself, the machine model, the zoning rule, and the turn-it-down-on-complaint standard. Leave the intensity band to the franchisee, since only they can judge their own building's air volume and HVAC correctly on-site.
Can a franchisor remotely check a franchisee's scent machine settings? No. The SOSA Vaayu's app is Bluetooth and on-site only, so there is no remote reading a franchisor can pull from head office.

The short answer
Short answer: yes to the fragrance and the machine standard, mandated in the operations manual with no substitutes - a SOSA Vaayu (₹11,999) as default, an Angaan (₹25,999) above a size threshold - but the intensity setting should be left to each franchisee, set to their own building's air volume and HVAC rather than one dial number for the whole network.
The pick: a SOSA Vaayu (₹11,999) mandated as the default franchise machine, stepping up to a SOSA Angaan (₹25,999) above an agreed size threshold.

A franchise agreement should mandate the fragrance and the machine model exactly, and leave the intensity setting to the franchisee's own building - mandating the dial number too is where well-meaning brand standards break down in practice.

Straight answer
Should a franchise agreement require every location to use the same scent machine and fragrance?
Yes, for the parts that make it a genuine standard, and no, for the one part that should stay local. Mandate the fragrance itself, ordered from one supplier under one code with no local substitutes - this is what makes the network recognisable. Mandate the machine model: a SOSA Vaayu (₹11,999, rated to 1000m³) as the default for a typical location, stepping up to a SOSA Angaan (₹25,999) only once a location crosses an agreed size threshold, such as roughly 8,000-10,000 sq ft on one HVAC loop. Mandate the zoning rule for which rooms are ever scented, and the standard that a patient's comment on the fragrance means turning it down. Do not mandate a single intensity number across the network - a franchisor writing the operations manual has not measured every location's air volume or HVAC, and a franchisee's own building is different from the flagship location the fragrance was originally trialled in. Leave the intensity band to the franchisee, set on-site to that specific building, and audit it with a physical walk-through by someone who has been out of the location for ten minutes, since there is no remote reading to check from head office - the Vaayu's own app is Bluetooth and on-site only. None of this is a claim that consistent scenting drives more revenue or footfall across the network; the honest benefit is a recognisable, considered environment at every location. A portion of every order supports girl-child education through Nanhi Kali.
Mandate the fragrance and the machine model. Leave the intensity setting to the franchisee's own building, checked by a physical audit.
Every franchise location runs the same SOSA Vaayu - waterless, under 38dB, rated to 1000m³ - as the mandated default machine, on the mandated fragrance, with the intensity band set locally to that specific building.

What the operations manual mandates
Fragrance, machine model and zoning rule, with no local variation
The two machines a franchise standard specifies
A franchise network specifies the same two machines everywhere. The fragrance and the model are non-negotiable; the setting is the franchisee's to get right for their own building.
A typical franchise location, the mandated default
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft. Bluetooth app, on-site control only, key-lock so the setting holds between franchisor audits. 400ml tank lasting up to 75 days, under 38dB.
From ₹11,999
A second unit for a larger location
SOSA Vaayu (second unit)
A larger franchise location may need a second Vaayu on the same mandated fragrance, with its own locally set intensity, rather than a single unit stretched past its honest coverage.
From ₹11,999
A location above the agreed size threshold
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, with an 800ml reservoir, metal body, programmable schedules and under 42dB running. The mandated step-up machine once a location crosses the threshold written into the operations manual.
From ₹25,999
What a franchise agreement should mandate, and what it should leave local
Three questions decide a franchise fragrance clause: what genuinely needs to be identical for the brand to work, what only the local operator can judge, and how the franchisor checks compliance without a remote system.
1
Mandate what makes the brand recognisable
The fragrance and the machine model, with zero local variation
A franchise fragrance only works as a brand asset if it is genuinely identical everywhere, ordered from one source, with no local substitution allowed. The machine model should be mandated the same way - a SOSA Vaayu as the default, an Angaan only above a written size threshold - so every location is comparing against the same physical equipment.
Tip: if a franchisee could swap it for something similar, it is not actually a standard.
One Vaayu model, one fragrance code, specified once in the operations manual for the whole network.
See SOSA Vaayu →
2
Leave the setting to the building it is in
Only the franchisee can judge their own air volume and HVAC
A head office cannot correctly set the intensity for a location it has not measured. The franchisee, standing in their own reception, is the only person positioned to tune the setting to that building's actual air exchange and reach the network's agreed perceived level.
A location running an Angaan above the size threshold still has its schedule and intensity set by whoever manages that specific building's HVAC.
See SOSA Angaan →
3
Audit by walking in, not by reading a dashboard
There is no remote check for a Bluetooth, on-site machine
Compliance checks need a person who has been out of the location for at least ten minutes walking back in and comparing what they smell against the network standard. There is no app dashboard a franchisor can check from head office, since the machine's control is deliberately local.
Tip: the walk-through is the audit. There is no substitute for it.
Because the Vaayu's intensity is adjustable in seconds, correcting a franchisee's setting after an audit takes moments once drift is actually noticed.

The SOSA principle
A franchise standard that mandates the dial number has mistaken uniformity for consistency. The two are not the same thing across buildings a franchisor has never measured.
Mandate what makes the brand recognisable. Leave what only the room itself can decide.
One machine standard, one fragrance, a local intensity band
The table is really the operations manual clause, split in two: the left column is fixed and enforceable, the right column is local and auditable.

A note from Sonal
A franchisor asked me to write the fragrance clause for their operations manual, and their first draft specified an exact intensity number for every location. I asked them to remove it, and here is why: a franchise network is, almost by definition, a set of buildings the franchisor did not build and does not control the HVAC of. Mandating the fragrance and the machine is enforceable and correct. Mandating a single dial number across buildings you have never measured is not.
What belongs in the franchise agreement or operations manual, mandated without exception: the fragrance itself, from one supplier, ordered under one code, with no local substitutes; the machine standard - a SOSA Vaayu (₹11,999) by default, stepping up to a SOSA Angaan (₹25,999) only where a franchise location crosses an agreed size threshold; the zoning rule for which rooms are ever scented; and the standard that a patient's comment means turning it down. What belongs to the franchisee, because only they can judge it correctly on-site: the intensity band, set to their specific building's air volume and HVAC, and the day-to-day running of the machine within that band.
Auditing this only works with a physical walk-through by someone who has been out of the location for ten minutes - there is no remote reading that substitutes for standing in the room, and the Vaayu's app itself is a Bluetooth, on-site control rather than something a franchisor can check from head office. None of this is a claim that consistent scenting drives more franchise revenue or footfall - the honest benefit is a recognisable brand experience across every location. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Should a franchise agreement mandate an exact scent machine intensity setting for every location?
No. It should mandate the fragrance itself and the machine model, but the intensity setting should be left to each franchisee, set to their own building's air volume and HVAC, since a franchisor cannot correctly set this for a location it has not measured.
What should a franchise fragrance standard specify?
The fragrance, ordered from one supplier with no local substitutes; the machine model, a SOSA Vaayu (Rs 11,999) as the default and a SOSA Angaan (Rs 25,999) above an agreed size threshold; the zoning rule for which rooms are scented; and the standard that a patient comment means turning the intensity down.
How does a franchisor audit compliance with a scent standard across locations?
With a physical walk-through by someone who has been out of the location for at least ten minutes, since there is no remote reading available - the SOSA Vaayu's app is Bluetooth and controls the machine on-site only, not from a head-office dashboard.
Can a franchisor check scent machine settings remotely across all locations?
No. The SOSA Vaayu's app connects over Bluetooth and is an on-site control. A franchisor auditing consistency needs an in-person walk-through at each location rather than a remote system.
Does consistent franchise scenting increase revenue or footfall?
SOSA makes no claim of that kind. The honest, provable benefit of a consistent fragrance standard across a franchise network is a recognisable, considered environment at every location, which is a brand-consistency argument, not a financial one.
Mandate the machine and the fragrance. Leave the dial to the building.
