Can the SOSA Vaayu app be controlled from head office for a multi-location SOP? No. The Vaayu's app is Bluetooth and short-range, an on-site control only. A usable SOP must name a real person at each branch who holds that branch's app pairing and key-lock, rather than assuming a central dashboard exists.
Who should check that a branch's scenting matches the SOP standard? Someone who has been out of the building for at least ten minutes, on a monthly walk-through - never the staff working in that branch every day, since olfactory adaptation means they are the worst judges of whether the level has drifted.

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.
Most scenting plans describe what should happen. An SOP is different - it names who does it, on what schedule, and what happens when it goes wrong - and here is the version that actually holds up across more than one location.
Quick answers — read this first
What should a scent SOP for a multi-location healthcare business include? The named fragrance, a zoning map of scented, light and fragrance-free rooms, the intensity band per branch, a named person per branch holding the SOSA Vaayu's app and key-lock, the refill interval and who checks it, an escalation route for clinician requests, and a monthly outside walk-through.Can the SOSA Vaayu app be controlled from head office for a multi-location SOP? No. The Vaayu's app is Bluetooth and short-range, an on-site control only.

The short answer
Short answer: a usable scent SOP names eight things: the fragrance, the zoning map by room type, the intensity band per branch, who holds the SOSA Vaayu's app and key-lock (Bluetooth, on-site only, no remote control), the refill interval and its checker, the escalation route for a clinician's request, a monthly outside walk-through, and a review date.
The pick: a SOSA Vaayu (₹11,999) per typical branch and a SOSA Angaan (₹25,999) for a flagship branch, documented in one SOP with a named holder and band per location.

An SOP that relies on staff noticing drift will fail, because olfactory adaptation means the person who works in a room all day is the worst judge of its level - the outside check is what makes this document actually work.

Straight answer
What does a genuinely usable scent SOP for a multi-location healthcare business need to contain?
A scenting plan and a scenting SOP are not the same document. A plan says what fragrance to use and where. An SOP names a person for every line, because a document that relies on someone remembering will fail exactly when it matters. Here is what a usable one contains:
- The fragrance - named exactly, one supplier, one order code, no branch substitutes.
- The zoning map - which room types are scented, which are light, and which are fragrance-free without exception (consultation, treatment, diagnostics, paediatrics, ENT, any room a patient lies down in).
- The intensity band for each named branch - a number range set on-site, never one figure for the whole chain.
- Who holds the app and the key-lock - a named person per branch, since the SOSA Vaayu's app is Bluetooth and on-site only, with no remote or cloud control.
- The refill interval and who checks it - a calendar owner, not an assumption that someone will notice the tank is empty.
- The escalation route - what happens, in minutes, when a clinician asks for a room cleared of fragrance.
- The monthly outside walk-through - done by someone who has been out of the building for at least ten minutes, comparing the branch against the written standard.
- The review date - a fixed point to re-check the whole document, not just the machines.
Name the fragrance, the zoning map, the band, the app holder, the refill checker, the escalation route and the monthly outside walk-through. That is the SOP.
Every branch in the SOP runs one SOSA Vaayu - waterless, under 38dB, rated to 1000m³, with a Bluetooth app that is on-site only - held by a named person at that branch, not a head-office login.

The two machines an SOP is written around
The SOP is written around two machines. Most branches use one Vaayu; a flagship branch on one HVAC loop uses an Angaan, named in the same document.
A typical branch, per the SOP's default line
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft. Bluetooth app, on-site control only, key-lock for the named holder, 400ml tank lasting up to 75 days, under 38dB.
From ₹11,999
A second unit for a larger branch
SOSA Vaayu (second unit)
Named in the SOP alongside the first unit for any branch large enough to need two, both held by the same named local person.
From ₹11,999
A flagship branch on one central HVAC loop
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, with an 800ml reservoir, metal body, programmable schedules and under 42dB running. Named in the SOP as the machine standard above the size threshold.
From ₹25,999
The eight lines a usable SOP needs, and why the outside check matters most
Three failure modes explain why most scenting plans are not really SOPs: nobody is named, the app's real limits are assumed away, and the only check available is the branch's own staff.
1
Name a person, not a role, per line
An SOP without a name is a wish, not a procedure
"Reception staff hold the app" is not a name. "Priya, front desk lead, holds the Vaayu app and key for the Andheri branch" is. Every line of the SOP - the app holder, the refill checker, the walk-through auditor - needs an actual person named against it, reviewed whenever staff change.
Tip: if a line names a role instead of a person, it will not get done reliably.
The Vaayu's single Bluetooth pairing per machine forces this naming decision early, rather than letting it stay vague.
See SOSA Vaayu →
2
Write the app's real limits into the document
Bluetooth is on-site only, and the SOP should say so plainly
An SOP that assumes remote control exists will fail on day one at any branch the author has not visited. Stating clearly that the app is Bluetooth, short-range and on-site only forces the document to name a real person at a real building for every location, which is exactly what makes the SOP usable rather than aspirational.
A flagship branch's Angaan is controlled at the building's HVAC plant room, by whoever manages that plant, following the same on-site logic.
See SOSA Angaan →
3
Build the outside check into the calendar
The branch's own staff are the worst judges of its level
Olfactory adaptation means a person working in a room all day stops registering its smell within minutes of arriving. The only test worth trusting is a monthly walk-through by someone who has been away from that specific branch for at least ten minutes, comparing what they smell against the written standard.
Tip: put a name and a date against the walk-through, exactly like every other line.
Because the Vaayu's intensity is adjustable on the spot, correcting a branch flagged by the walk-through is a two-minute fix, not a re-installation.

The SOSA principle
A scenting plan describes what should happen. An SOP names who does it, and what happens when nobody does. Most healthcare groups only have the first document.
The line that actually saves an SOP is the one naming who checks it from outside the building, not the fragrance itself.
One document, one fragrance, a band and a name per branch
The table below is the SOP's eight lines, reduced to what each one actually needs to say to be usable rather than decorative.

This document is the practical output of the standardise-and-vary principle covered in should every branch of a polyclinic chain smell the same, and the franchise-specific version of the same idea sits in should every franchise clinic receive the same scent machine and fragrance. The pillar guide, what a premium multi-speciality polyclinic should smell like, covers the fragrance direction the SOP names.

A note from Sonal
Owners ask me for a scenting plan and I give them a machine and a fragrance. Owners ask me for a scenting SOP and I give them a document, because a plan describes what should happen and an SOP describes who does it, on what schedule, and what happens when it goes wrong. Multi-location healthcare businesses need the second one, and most of what I see written for this purpose is really just the first one with a letterhead.
A genuinely usable SOP has eight lines, and none of them can be vague: the fragrance, named exactly, from one supplier; the zoning map, naming which room types are scented, which are light, and which are fragrance-free, without exception for consultation, treatment, diagnostics, paediatrics and ENT; the intensity band for each named branch, not a chain-wide number; a named person at each branch who holds the app pairing and the key-lock for their SOSA Vaayu (₹11,999) - and here I have to be direct, because it trips up almost every group planning this: the Vaayu's app is Bluetooth and short-range, an on-site control only, with no cloud dashboard, so this line has to name an actual person at the actual building; the refill interval and who checks it, since a 400ml tank lasts up to about 75 days depending on intensity and run hours and someone needs to own that calendar; the escalation route for when a clinician asks for a room cleared, which should take minutes, not a committee; and a monthly walk-through, done by someone who has been out of the building for at least ten minutes, because staff working in a branch stop noticing its smell within days and cannot be trusted to catch drift on their own.
A larger flagship branch on one central HVAC loop uses a SOSA Angaan (₹25,999) instead, and the same document applies to it with the machine name swapped. None of this SOP claims anything about air hygiene, patient anxiety or bookings - it is an operations document for a hospitality decision, and it works because it is specific. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What should a multi-location scent SOP include?
Eight named items: the fragrance, the zoning map of scented, light and fragrance-free rooms by type, the intensity band for each branch, a named person per branch holding the app and key-lock, the refill interval and who checks it, the escalation route for a clinician's request, a monthly outside walk-through, and a review date.
Can the SOSA Vaayu app be managed from a central office across all locations?
No. The app is Bluetooth and short-range, an on-site control only, with no cloud dashboard. A usable SOP names a real person at each branch who holds that branch's app pairing and key-lock, rather than assuming remote control from head office.
Who should do the monthly walk-through check in a scent SOP?
Someone who has been out of the branch for at least ten minutes before re-entering, never the staff who work in that room every day. Olfactory adaptation means people exposed to a smell all day stop noticing it and cannot reliably catch drift from the standard.
What should the escalation route in a scent SOP cover?
A clear, fast process for when a clinician asks for a room cleared of fragrance - it should take minutes, not require a committee, and the clinician's judgement should always override the scenting plan for that room.
Does a scent SOP for a healthcare business need to mention air hygiene or patient anxiety?
No, and it should not claim either. A scent SOP is an operations document for a hospitality and brand-consistency decision. SOSA makes no claim that fragrance improves air hygiene, reduces infection risk, or eases patient anxiety.
