Should every experience centre in a chain run the same fragrance intensity? No - the intensity should be tuned per site to produce the same felt level, not the same dial number. A SOSA Angaan (Rs 25,999) or Vaayu (Rs 11,999) at identical settings will smell different in humid coastal air than in a dry inland city, so each site needs its own calibration against the same target level.
Who should be responsible for scent consistency at each experience centre? Name one person per site who holds the app and the key-lock, responsible for the refill interval and routine checks, plus a monthly walk-through from someone who has been outside the building for ten minutes - because the staff working there daily are the worst judges of the level, due to olfactory adaptation.

Facts verified 24 August 2026 against the live SOSA product pages: 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, connecting to the building's HVAC or standing alone wall-mounted. The SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, roughly 2,000-3,000 sq ft, with a 400ml tank lasting up to about 75 days, a Bluetooth app with 1h/4h/8h/24h timers, adjustable intensity, key-lock and operation under 38dB. 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.

How do you keep several smart-home experience centres smelling consistently on-brand? Not by running every machine at the same setting - standardise the fragrance and the rule, and let intensity and machine count vary honestly by building, because what a visitor registers is the level in the room, never the number on the dial.
Quick answers — read this first
How do I standardise scenting across multiple smart-home experience centres? Standardise two things everywhere - the fragrance itself and the scheduling rule - and let intensity and machine count vary honestly by building, because ceiling height, air volume and local climate differ from site to site. A humid coastal centre holds scent longer than a dry inland one at the same setting, so the number on the dial should never be the standard, only the level a visitor actually experiences.Should every experience centre in a chain run the same fragrance intensity? No - the intensity should be tuned per site to produce the same felt level, not the same dial number. A SOSA Angaan (Rs 25,999) or Vaayu (Rs 11,999) at identical settings will smell different in humid coastal air than in a dry inland city, so each site needs its own calibration against the same target level.

The short answer
Short answer: standardise the fragrance and the scheduling rule everywhere; vary intensity and machine count by building and climate, since humid coastal air holds scent longer than dry inland air at the same setting; name who holds the app and key-lock at each site.
The pick: the SOSA Angaan (₹25,999) for each experience-centre floor on the HVAC, with a SOSA Vaayu (₹11,999) for a demo zone off the main system.
Next step: name a key-lock holder and a monthly walk-through check per site, then write to us to calibrate intensity across your locations.

Straight answer
How do I standardise scenting across multiple smart-home experience centres?
Standardise the two things that actually define the brand experience, and deliberately leave the rest to vary by site. Standardise the fragrance - the same signature scent across every location, ordered as the same set for every SOSA Angaan (₹25,999) or SOSA Vaayu (₹11,999) in the chain. Standardise the rule, not the setting - for example, "run continuously at the lowest level a fresh-nosed visitor notices on arrival" is a rule every site can follow; "run at intensity level 3" is a number that produces a different result in every building. Then let intensity and machine count vary by site: ceiling height and air volume differ from centre to centre, and so does climate - a humid coastal city holds a scent noticeably longer than a dry inland one at the identical setting, so a coastal centre may need a lower intensity to hit the same felt level as an inland one running higher. For each site, name a specific person who holds the Bluetooth app and the key-lock, responsible for the refill interval and routine checks - the app is on-site only, so this cannot be managed remotely from head office. And build in a monthly walk-through by someone who has been outside the building for ten minutes, because the staff who work there every day have adapted to the level and are the worst judges of it; a fresh nose from outside is the only reliable check. If you are rolling this out across several locations, write to us and we will help calibrate intensity site by site.
Standardise the fragrance and the schedule rule. Vary intensity and machine count by building and climate. Name who holds the app and key-lock per site, and run a monthly outside-nose walk-through.
For each experience-centre floor, the standard usually runs on a SOSA Angaan - HVAC-connected, rated to 3,000m³, running the same signature fragrance everywhere, calibrated to intensity per site.

What is standardised
The fragrance and the scheduling rule, everywhere
The two machines a multi-site standard is built from
A multi-site standard is built from two machines: the Angaan for each experience-centre floor on the HVAC, and the Vaayu for a demo zone off the main system. Both link straight to the product page so every site manager can check the specification.
The signature scent, every floor on the HVAC
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³ - about 8,000-10,000 sq ft. Programmable schedules, under 42dB, 800ml reservoir. The same fragrance ordered for every site.
From ₹25,999
A demo zone off the main HVAC
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³, for a demo room not on the centre's central air handling. Bluetooth app, key-lock, 1h/4h/8h/24h timers.
From ₹11,999
A second demo zone at a different site
SOSA Vaayu (second unit)
Each additional site's demo zone runs its own Vaayu, calibrated to that building's air volume and climate.

What stays the same, and what should genuinely differ by site
Three decisions keep a multi-site standard honest: what stays fixed, what is named per site, and who checks it.
1
What stays fixed
The fragrance itself, and the scheduling rule
Order the same signature scent for every SOSA Angaan or Vaayu in the chain, and write the schedule as a rule rather than a number - "run continuously at the lowest level a fresh-nosed visitor notices" travels across sites; "run at setting 3" does not, because the same setting produces a different felt level in a double-height atrium than in a low-ceilinged demo room.
Tip: standardise the rule, not the dial - the dial should differ by building.
The Angaan's programmable schedule is set once per site to hit the rule, not a fixed number copied from another location.
See SOSA Angaan →
2
What is named per site
Who holds the app and key-lock, and the refill interval
The Vaayu's Bluetooth app is on-site only, so it cannot be managed remotely from a head office - each location needs one named person responsible for the schedule, the key-lock, and noticing when a refill is due. Humid coastal sites also hold scent longer than dry inland ones at the same setting, which is worth noting explicitly against that site's name, not assumed to be identical everywhere.
The Vaayu's key-lock exists precisely because on-site control needs an accountable person, not a remote setting.
See SOSA Vaayu →
3
Who checks it
A monthly walk-through from someone who has been outside
Staff working in a building daily adapt to its fragrance level within days and stop reliably noticing it - the same olfactory adaptation that makes homeowners the worst judges of their own house. Build in a monthly check by someone who has been outside for at least ten minutes, or by a visiting regional manager, rather than relying on the on-site team's own impression.
Tip: the people in the building every day are structurally the worst judges of its level.
A regional walk-through checking the Angaan's felt level catches drift long before a customer comments on it.

The SOSA principle
A visitor moving between your locations should recognise the brand's fragrance instantly, and never notice that the intensity differs from site to site.
That is only possible if the standard protects the felt level, not the number on the dial - and the two are rarely the same across buildings.
Standardise the fragrance and the rule, not the dial
There is no single setting that works everywhere, and pretending otherwise is how a chain ends up with one site too strong and another too faint, both technically compliant with the same number.

If a single centre's own demo floor needs sorting first, whether an experience centre can demonstrate fragrance live and whether scent machines should be displayed alongside lighting and audio both cover the ground-level version of this same standard. For the wider argument on why the air deserves the same planning as every other system, see the pillar guide on automating fragrance like lights, curtains and air-conditioning.
Standardise the rule, not the dial
SOSA Angaan (₹25,999) runs the same signature scent at every site - calibrated per building, checked monthly from outside.
The staff who work in a building every day are the last people who can tell you whether it smells right. That is exactly why the standard needs an outside nose, on a schedule.

What the standard actually specifies
A multi-site standard runs on two machines: the Angaan for each experience-centre floor on the HVAC, the Vaayu for a demo zone off the main system. Both are waterless, made in India, and calibrated per site against one shared standard. A portion of every order supports girl-child education through Nanhi Kali.

A note from Sonal
A chain with five experience centres once told us proudly that every site ran the exact same setting on the app, as if that were the definition of consistency. Two of their five locations were in humid coastal cities and the other three inland, and the coastal sites were noticeably stronger than intended. Same number, different result - because the air itself was different.
What we standardised instead was the fragrance itself, ordered identically for every SOSA Angaan (₹25,999) and SOSA Vaayu (₹11,999), and a rule - run continuously at the lowest level a fresh-nosed visitor would notice - rather than a number. Each site then calibrated its own intensity to hit that rule, coastal sites running lower than inland ones for the same felt effect. We also asked them to name one person per site responsible for the app and key-lock, and to schedule a monthly walk-through by someone who had been outside for ten minutes, because the on-site team had simply stopped smelling their own building.
That is the whole standard: same scent, same rule, different dial, named accountability, and an outside nose once a month. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How do I standardise scenting across multiple smart-home experience centres?
Standardise the fragrance itself and the scheduling rule across every site - the same signature scent, and a rule like running continuously at a low, settled level. Let intensity and machine count vary honestly by building and climate, since a humid coastal centre holds scent longer than a dry inland one at the same setting.
Should every location run the same fragrance intensity setting?
No. The same setting produces a different felt level depending on the building's air volume and local humidity. Calibrate each site's intensity to hit the same experienced level, not the same number on the dial.
Who should manage the scent machine at each experience centre?
Name one specific person per site who holds the Bluetooth app and the key-lock, responsible for the refill interval and routine checks. The app is on-site only, so this role cannot be managed remotely from a head office.
Why can staff working at a centre not judge whether the fragrance level is right?
Because of olfactory adaptation - anyone in a space for more than a few days stops reliably noticing its baseline smell. A monthly walk-through by someone who has been outside for at least ten minutes gives a far more reliable check.
Does humid coastal climate affect how a scent machine should be set?
Yes. Humid air tends to hold fragrance noticeably longer than dry air at an identical setting, so a coastal site may need a lower intensity than an inland one to reach the same felt level.
