Does the SOSA Vaayu app allow central control across a whole campus? No. The Vaayu app is Bluetooth and short-range, on-site only - there is no central dashboard for controlling every machine across a multi-building campus remotely. A responsible SOP names a specific, on-site holder for each zone's app rather than assuming central control exists.
Why does a scenting SOP need a monthly walk-through by someone from outside the building? Because everyone who works in or near a scented zone becomes adapted to it over time and loses the ability to judge whether the level is still correct. A person who has been away from the building for at least ten minutes can smell the zone with a fresh nose and catch drift before it becomes a complaint.

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 (short-range, on-site only, with no central dashboard), 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.

Every question in this series points toward one document. Here is what a genuinely usable commercial scenting SOP for a large tech campus actually contains, written plainly enough to hand to a facilities team on day one.
Quick answers — read this first
What should a responsible commercial scenting SOP for a large tech campus include? Eight named items: the fragrance; the scented and neutral zones by room type; the intensity band per zone; who holds the app and key-lock; the refill interval and who checks it; the complaint and switch-off route; and a monthly walk-through by someone who has been out of the building for at least ten minutes, since everyone inside is adapted to the scent.Does the SOSA Vaayu app allow central control across a whole campus? No. The Vaayu app is Bluetooth and short-range, on-site only - there is no central dashboard for controlling every machine across a multi-building campus remotely. A responsible SOP names a specific, on-site holder for each zone's app rather than assuming central control exists.
Why does a scenting SOP need a monthly walk-through by someone from outside the building?

A person who has been away from the building for at least ten minutes can smell the zone with a fresh nose and catch drift before it becomes a complaint.
The short answer
Short answer: a responsible SOP names the fragrance, the scented and neutral zones by room type, the intensity band, who holds the app and key-lock, the refill interval and who checks it, the complaint and switch-off route, and a monthly walk-through by someone away from the building for 10+ minutes - and it states plainly that the SOSA Vaayu app (₹11,999) is Bluetooth and short-range, on-site only, with no central campus dashboard.
The pick: a standalone SOSA Vaayu (₹11,999) per visitor-facing zone with a named on-site app holder, and a SOSA Angaan (₹25,999) for a larger zone on one shared HVAC loop with the system owner named in the SOP.
Next step: use the eight-point structure below as a starting draft, or book a free scenting plan and we will help you write the full SOP.

Straight answer
What would a responsible commercial scenting SOP look like for a large Bengaluru tech campus?
It names eight things, in writing, before any machine is switched on. 1. The fragrance - one signature, used identically across every scented zone. 2. The scented and neutral zones by room type - reception, visitor lounge, executive floors and client meeting suites may carry it; general work areas and workstations stay neutral, unhedged. 3. The intensity band for each zone - fuller in an open lobby, lower in a closed meeting suite, always kept modest rather than strong. 4. Who holds the app and the key-lock - a named person per zone, not a shared login nobody is accountable for. 5. The refill interval and who checks it - tied to the machine's actual runtime, not guessed. 6. The complaint and switch-off route - who receives a complaint, who is authorised to switch the zone off, and how fast, with one complaint always treated as sufficient. 7. A standing unscented area, existing at all times regardless of complaints. 8. A monthly walk-through by someone who has been out of the building for at least ten minutes, because everyone inside is adapted to the fragrance and cannot judge it accurately - facilities staff included. One specification fact belongs explicitly in the document, stated rather than assumed: the SOSA Vaayu (₹11,999) app is Bluetooth and short-range, on-site only - there is no central dashboard across a campus, and a facilities manager used to other building systems will otherwise assume one exists. Write the SOP around a named, on-site app holder per zone instead. A SOSA Angaan (₹25,999) on shared HVAC needs the same eight points, with the air-handling system owner added to the refill and switch-off lines. A free scenting plan can help you turn this into your campus's actual document, and a portion of every order supports girl-child education through Nanhi Kali.
Eight items, written down: fragrance, zones, intensity, app and key-lock holder, refill interval, complaint route, standing unscented area, and a monthly outside-nose check.
The machine most zones in this SOP are written around is a standalone SOSA Vaayu - waterless, under 38dB, rated to 1000m³ (about 2,000-3,000 sq ft), key-locked, with an app that is Bluetooth and short-range, on-site only. A SOSA Angaan covers a larger zone on one shared HVAC loop with the same documentation.

The eight things a usable SOP names, in writing
Three things separate a usable SOP from a document nobody follows: writing down what most teams assume rather than state, being honest about what the app can and cannot do across a campus, and building in the one check that catches drift before a complaint does.
1
Write down what is usually assumed
The fragrance, the zones, the intensity band, in one document
Most fragrance problems on a large campus trace back to something nobody wrote down - which zones were meant to be scented, what intensity was intended, who was supposed to be checking the refill. An SOP's whole value is turning tacit assumptions into a document a new facilities hire can follow without having to ask anyone. Start with the fragrance and the zone list; everything else follows from those two lines.
Tip: if it is not written down, it is not actually policy - it is one person's memory.
A Vaayu per named zone, with its holder and schedule documented, is the physical form of that written policy.
See SOSA Vaayu →
2
Be honest about the app - no central dashboard exists
Bluetooth and short-range, on-site only
A facilities manager coming from other building systems - access control, HVAC management, lighting - will reasonably expect a central dashboard for a campus-wide scent system too. The Vaayu app does not offer that; it is Bluetooth and short-range, meaning control happens on-site, zone by zone. State this in the SOP itself so the plan is built around named, on-site holders rather than a control room that does not exist.
An Angaan on shared HVAC is programmed and checked the same way - on-site, by a named holder, not remotely from a central system.
See SOSA Angaan →
3
The monthly check has to come from outside
Everyone inside is adapted - the check cannot come from them
Facilities staff who work near a scented zone every day lose the ability to judge its intensity accurately, the same way anyone adapts to a familiar smell. Build in a monthly walk-through by someone who has genuinely been away from the building for at least ten minutes - a different staff member returning from a break, or a visitor's honest reaction - as the SOP's only reliable check against gradual drift.
Tip: the monthly check is only valid from a nose that has been outside for ten minutes.
A Vaayu's adjustable intensity makes correcting drift, once it is caught, a two-minute app adjustment rather than a hardware change.

The SOSA principle
A scenting policy that lives in one person's head is not a policy - it is a habit that ends the day that person is unavailable. Writing it down is most of the work.
The question is never whether the plan is right. It is whether anyone but you could follow it tomorrow.
Vaayu or Angaan, and what each needs written into the SOP
Here is the whole decision in one table. Every zone in the SOP is a Vaayu question, sized and documented individually, or an Angaan question for a larger shared loop with its own documented ownership.

Our Bengaluru pillar guide covers what to diagnose before buying any commercial scent machine in the first place.
Eight items, one machine per zone, written down properly
SOSA Vaayu ₹11,999 covers up to 1000m³ - about 2,000-3,000 sq ft. We will help you turn this structure into your campus's actual SOP.
The Vaayu app is Bluetooth and short-range, on-site only. There is no dashboard watching the whole campus - the SOP has to name a person for every zone instead.

The SOSA specification behind the SOP
Two machines, one written SOP: the Vaayu per visitor-facing zone, each with a named holder; the Angaan for a larger zone on one shared HVAC loop, with the system owner documented alongside it. Both waterless, both made in India. A portion of every order supports girl-child education through Nanhi Kali.

A note from Sonal
Everything in this series adds up to one document, and I would rather hand you the actual document than another principle. A responsible commercial scenting SOP for a large campus names eight things, in writing, before the first machine is switched on: the fragrance itself; the scented and neutral zones by room type; the intensity band for each zone; who holds the app and the key-lock; the refill interval and who checks it; the complaint and switch-off route; and a monthly walk-through by someone who has been outside the building for at least ten minutes.
That last point is not a formality. Everyone inside a building is adapted to the fragrance they work near - the facilities team most of all - so nobody who has been in the building all day can honestly judge whether the level is still right. A monthly check by someone freshly arrived is the only reliable way to catch drift before a complaint does. And one specification detail belongs in every version of this SOP, stated plainly rather than assumed: the SOSA Vaayu app is Bluetooth and short-range, on-site only. There is no central dashboard that lets one facilities manager see or control every machine across a multi-building campus from a laptop. A facilities manager will assume that dashboard exists, because most other building systems have one - it is worth saying out loud, in the SOP itself, that this one does not, so the plan is built around a named, on-site holder for each zone's app rather than a central control room that is not coming.
A SOSA Angaan on shared HVAC needs the same eight items, with the zone's air-handling owner added to the refill and switch-off lines. None of this is complicated once it is written down - it is simply rarely written down, which is exactly why complaints and drift happen. Everything SOSA makes is manufactured in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What are the essential items in a commercial scenting SOP for a large campus?
The fragrance used; the scented and neutral zones by room type; the intensity band per zone; who holds the app and key-lock; the refill interval and who checks it; the complaint and switch-off route; a standing unscented area; and a monthly walk-through by someone who has been outside the building for at least ten minutes.
Can one facilities manager control every scent machine across a campus from a central dashboard?
No. The SOSA Vaayu app is Bluetooth and short-range, meaning control is on-site only, zone by zone - there is no central dashboard across a multi-building campus. A usable SOP names a specific on-site holder for each zone's app rather than assuming remote, central control.
Why does a monthly walk-through need someone from outside the building?
Because people who work near a scented zone every day become adapted to it and lose the ability to judge its intensity accurately, including facilities staff themselves. A person who has been away from the building for at least ten minutes provides the only reliable, fresh-nose check against gradual drift.
How often should a commercial scent machine be refilled on a large campus, and who checks it?
The interval should be tied to the machine's actual runtime - a SOSA Vaayu's 400ml tank lasts up to about 75 days depending on intensity and hours run - and the SOP should name a specific person responsible for checking and refilling each zone's machine on that schedule, not leave it to whoever notices it running low.
Should the SOP be different for a zone on shared central HVAC?
Yes - a zone using a SOSA Angaan on shared HVAC needs the same eight items as any other zone, with the air-handling system's owner added specifically to the refill checking and complaint switch-off lines, since decisions there affect more than one room.
