How much lower should the private room be? As a working rule, somewhere between a third and a half of what reception carries, and the smaller and more sealed the room is, the further down that range you go. In a room under about 150 sq ft with the door closed for an hour, nothing at all is a legitimate setting.
How do you produce that difference physically? Two ways. Either one source in reception and nothing in the meeting room, so the small room carries only the trace it inherits through the door; or a genuinely smaller format of its own — fewer fibre reeds, a smaller bottle, a separate machine on its own schedule. What does not work is one source covering both rooms with the dial turned down a little.

Facts verified 5 September 2026 against the live SOSA product pages: the SOSA reed diffusers are alcohol-free, phthalate-free and paraben-free compositions on a heat-stable coconut-derived base, supplied in a refillable glass bottle with six fibre reeds, flipped weekly, with 50ml lasting 6-8 weeks and 130ml lasting 14-18 weeks, tested at 45°C and 85% relative humidity - Mountain Breeze ₹849 / ₹1,349, Morning Freshness ₹749 / ₹1,249, Evening Calm ₹799 / ₹1,299. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering about 270-320 sq ft for 16-18 hours on the low setting and supplied with three 15ml Hotel Collection fragrances; being ultrasonic, it works by aerosolising water and therefore adds some moisture to the air, which is worth weighing in a warm, high-occupancy room. 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 roughly 75-90 days a fill depending on intensity and run hours, Bluetooth app and onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, DC 12V/1A at 5W (roughly 1.5 units of electricity a month on a ten-hour daily schedule, and tariffs vary), freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification - which are electrical and compliance marks, not medical approval. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment; refill availability should be confirmed with SOSA. 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. Coverage figures are volumetric, so ceiling height changes the floor area a machine genuinely serves. SOSA products are not medical devices and no health, therapeutic, wellbeing or air-treatment claim is made or implied anywhere in this guide, and nothing here claims that ambient scent affects sales, orders, enquiries, footfall, conversion or any other business number - no one can promise that, and this guide does not. Ambient scent is an interior decision that works alongside cleaning, ventilation, air handling and housekeeping and is never a substitute for any of them, and SOSA sells no deodoriser, purifier, dehumidifier or extractor. Ventilation rates, plant and laboratory air handling, pressure regimes, HVAC filtration and any decision about where a fragrance source may or may not be placed on a regulated site are matters for the company's own engineering, QA and EHS teams. Clinical, treatment and procedure areas are left completely unscented. Fragrance sensitivity is real: staff should be able to switch any system off in seconds, and no SOSA product is described as hypoallergenic or as safe for sensitive individuals. 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.
Two rooms, ten steps apart, and the same bottle can be right in one and wrong in the other. The reception of an Alkapuri advisory suite is a wide room with a door that swings all morning. The meeting room behind it is a small box with the door shut for an hour at a time. Put the same level into both and the second one is carrying far more than it needs long before anybody stands up.
Quick answers — read this first
Should reception and the private meeting rooms run the same intensity? No. They should run the same oil and two different levels, and the private room is always the lower of the two. That is not a stylistic preference — it follows from the volume of air in each room and from how often that air is replaced.How much lower should the private room be? As a working rule, somewhere between a third and a half of what reception carries, and the smaller and more sealed the room is, the further down that range you go. In a room under about 150 sq ft with the door closed for an hour, nothing at all is a legitimate setting.
How do you produce that difference physically? Two ways. Either one source in reception and nothing in the meeting room, so the small room carries only the trace it inherits through the door; or a genuinely smaller format of its own — fewer fibre reeds, a smaller bottle, a separate machine on its own schedule. What does not work is one source covering both rooms with the dial turned down a little.
The short answer
Short answer: Same fragrance, two levels, private room always lower — usually a third to a half of reception. Build the difference into the hardware, not into a setting: one source in the open room, and either nothing or a much smaller format in the closed one.
The pick: Mountain Breeze at ₹1,349 for 130ml with all six fibre reeds in reception, and either nothing in the meeting room or the ₹849 50ml bottle with two or three reeds instead of six. SOSA Sukoon at ₹1,899 only where the meeting room is sealed enough to inherit nothing and you want a schedule.
The honest limit: This page is about air volume, air exchange and where a bottle sits. It makes no claim about anything that happens to the people in either room. Nobody can promise that a scent moves a business number, and this guide does not try to.
In this guide
The register is a suite-wide decision and the level is a room-by-room one — and the level is set by how much air the room has and how often that air is replaced.

Straight answer
Should the reception and the private client meeting rooms use the same fragrance intensity?
No — and the two halves of that answer are not equally negotiable. The fragrance should be the same in both rooms. The intensity should not, and the private room is always the lower of the two. Start with the part that does not change: one register across the whole suite. A visitor who meets pine and cedar at the entrance and something else behind the meeting-room door has been through two buildings in thirty seconds, and the suite stops reading as one practice. One oil, everywhere, for as long as you keep it.
Now the part that does change. A reception in an Alkapuri or Akota practice is typically three to five times the floor area of the meeting room behind it, and it sits on a door that opens all day, so its air is being replaced continuously. A private client room is small, has one door that stays shut for the length of an appointment, and often has its own air-conditioning loop with the return grille a metre from the table. Put an identical source in each and you have not given the two rooms the same fragrance level — you have put the same hourly output into a fraction of the volume with a fraction of the exchange, and over forty minutes it accumulates. The small room ends up several times heavier than the big one, which is the opposite of what almost everybody intends when they buy a matching pair.
So the private room is lower. How much lower is a judgement, but a third to a half of what reception carries is the range I work in, and the smaller and tighter the room, the further down that range it goes. Under about 150 sq ft with the door closed, nothing at all in the room is a perfectly good specification — and it is the one I recommend most often.
The part people get wrong is not the number. It is the mechanism. You cannot produce two levels from one source by turning it down a bit. A machine has one setting for the whole connected volume it serves; a dial is a single number, not a map. If reception and the meeting room are served by the same source at the same distance, they get the same level, and lowering it lowers both. The difference has to be built into the hardware. The first way is inheritance: one source in reception, nothing in the meeting room, and the small room carries only the trace that crosses the threshold when the door opens between appointments. That trace is usually already the right level, which is why this is the default. The second way is a smaller format of its own, for a room sealed tightly enough that it inherits nothing: fewer fibre reeds in a smaller bottle, or a separate machine on its own schedule, placed as far from the chairs as the room allows.
In practice that is Mountain Breeze at ₹1,349 for 130ml with all six reeds standing in reception, and in the meeting room either nothing, or the ₹849 50ml bottle with two or three reeds in it rather than six. Reed count is a real physical control and it costs nothing to use. Where a closed room genuinely needs its own switch and schedule, SOSA Sukoon at ₹1,899 runs a 270–320 sq ft room independently, at the price of some added moisture because it works by aerosolising water. And once reception, the corridor and the meeting rooms are a single connected volume past roughly 1,500 sq ft, SOSA Vaayu at ₹11,999 sits once in the open room and lets distance and a closed door do the lowering for you, key-locked so the level cannot drift upward between visits. Nobody can promise that a scent moves a business number, and this guide does not try to. What this decision controls is an interior, and nothing beyond it.
Now the part that does change.

No. Same oil, different level, private room always lower — usually a third to a half of reception. Produce the difference physically: one source in reception with the meeting room inheriting a trace through the door, or a smaller format of its own — fewer reeds, smaller bottle, separate schedule. Mountain Breeze ₹849 and ₹1,349; SOSA Sukoon ₹1,899 for a sealed room with its own switch; SOSA Vaayu ₹11,999 once the suite is one connected volume.
One register for the whole suite: Mountain Breeze — Himalayan pine, sage and Indian cedar, alcohol-free, ₹1,349 for 130ml in reception and ₹849 for the 50ml bottle if a closed room needs a little of its own.

SOSA Mountain Breeze
Himalayan pine with sage and Indian cedar on an alcohol-free, coconut-derived base. Six fibre reeds supplied, flipped weekly. 130ml at ₹1,349 lasts 14–18 weeks and is the reception bottle; 50ml at ₹749 in Morning Freshness or ₹849 here lasts 6–8 weeks and, with two or three reeds standing instead of six, is the closed-room bottle.
From ₹849
Only for a sealed meeting room that inherits nothing
SOSA Sukoon
270–320 sq ft of coverage at ₹1,899, 16–18 hours on the low setting, with three 15ml fragrances included. A genuine second zone with its own switch and its own schedule — run it for twenty minutes before an appointment rather than through it. Being ultrasonic it aerosolises water, so it adds some moisture to a small closed room in a humid month.
From ₹1,899
The three things that decide the second level
One of these is arithmetic, one is a mechanism and one is the mistake almost everybody makes on the way to the mechanism.
1
Volume and exchange, not room count
The small room has less air and replaces less of it
A 450 sq ft reception at nine and a half feet is somewhere around 4,300 cubic feet of air, and the entrance door hands a share of that back to the street every few minutes. A 130 sq ft meeting room is nearer 1,200 cubic feet, and for the length of an appointment the door does not move at all. The same hourly output therefore does two completely different things: in the open room it is continually being carried away, and in the closed room it stays and adds to what is already there.
Tip: Multiply floor area by ceiling height for both rooms before you buy anything. If the closed room is under a quarter of the reception volume, it does not get its own source.
Mountain Breeze is the suite register — ₹1,349 for the 130ml reception bottle and ₹849 for a 50ml bottle if a closed room genuinely needs its own trace.
See Mountain Breeze →
2
Inheritance is the default mechanism
The trace that crosses the threshold is usually the right level
A meeting room with no source of its own is not an unscented room. Every time the door opens between appointments it takes a share of reception's air, and the air-conditioning loop moves a little more of it around. What the room ends up holding is a faint version of the same register — which is exactly the specification you were trying to buy. This costs nothing, needs no second purchase, and cannot drift out of proportion with reception, because it is derived from it.
Tip: Leave the meeting-room door open between appointments and shut for them. That single habit is the whole mechanism, and it is free.
SOSA Vaayu at ₹11,999 sits once in the open room; the closed rooms sit lower because they are further away and behind a door, which is geometry rather than a setting.
See SOSA Vaayu →
3
A dial is one number, not a map
Turning it down a bit lowers both rooms together
This is where the plan usually fails. One source serving a connected volume produces one level across that volume, adjusted only by distance. Reduce the setting because the meeting room is heavy and reception goes quiet at the same moment, which is the room you could least afford to lose. Two rooms at two levels is a hardware question — how many sources, what size, how far from the seats, behind which door — and it is answered before anything is switched on rather than afterwards.
Tip: Count reeds, not settings. Six fibre reeds in reception and two in a small closed room is a real two-level system that no dial can imitate.
SOSA Sukoon at ₹1,899 is a genuinely separate zone for a sealed room, with its own switch and schedule, at the price of some added moisture.
See SOSA Sukoon →
The SOSA principle
Reception is a room whose air is constantly being replaced. A closed meeting room is a room whose air is not. The same output that keeps disappearing from one accumulates in the other, and an hour is long enough for that difference to become obvious.
Which is why the private room is specified lower before anyone sits in it, rather than adjusted once somebody has.
The two rooms, side by side
Not a scent comparison this time — a room comparison, because the fragrance is the same in every line and only the volume, the door and the hardware change.
The SOSA plan
One register, two rooms, two pieces of hardware
| The Room in an Alkapuri Suite | The Air It Has and How Often It Changes | How the Level Is Produced Physically |
|---|---|---|
|
Reception, around 450 sq ft, door on the street
|
Roughly 4,300 cubic feet, and a share of it handed back to the street every few minutes | One 130ml bottle with all six fibre reeds standing, two-thirds into the room — ₹1,349 |
|
A 130 sq ft meeting room, door shut for an hour
|
Nearer 1,200 cubic feet, with almost no exchange for the length of the appointment | Nothing of its own. It inherits a trace each time the door opens between appointments |
|
A closed room that genuinely inherits nothing
|
Its own small volume, its own still air, its own return grille | A 50ml bottle with two or three reeds instead of six, placed away from the chairs — ₹849 |
|
A sealed room where you want a switch and a schedule
|
270–320 sq ft run as an independent zone | Twenty minutes before the appointment, off during it — ₹1,899, with some added moisture |
|
Reception, corridor and meeting rooms as one volume
|
One connected volume past roughly 1,500 sq ft | One source in reception; distance and a closed door produce the lower level — ₹11,999 |
How long the appointment runs is the other input to the same number, and it is worked through in what to do when clients spend 45–90 minutes in the office. Which rooms belong in the plan at all — cabins, records, pantry — is settled in whether a wealth advisor, CA or consultant should scent the client reception. If your entrance never stops moving, what a constantly opening door does to scent diffusion explains why the front of reception is the least stable part of the suite, and whether a Vaayu is too powerful for a 700–1,000 sq ft office is the honest sizing answer before you buy anything at all.
Two rooms, two numbers
Send us the floor areas, the ceiling height and how long a typical appointment runs, and we will tell you what goes in each room — including where the answer is nothing.
A dial gives you one number for the whole floor. Two rooms at two levels is a question of where the bottle sits, not what the bottle is set to.

The register is a suite decision and the level is a room decision. Ambient scent here is an interior decision like lighting or joinery, with no health, therapeutic, wellbeing or air-treatment claim of any kind, and no claim that it affects enquiries, fees, retention or any other business number. It works alongside your cleaning and ventilation, never instead of them. The Vaayu tank runs roughly 75–90 days a fill depending on intensity and run hours, and refills are confirmed with SOSA. Ask for a room-by-room plan and we will size both rooms properly.

A note from Sonal
The matching pair is the most common thing I have to unwind. Somebody buys two identical diffusers because the reception and the meeting room are part of the same practice and it feels inconsistent to treat them differently. Two weeks later the meeting room is the room nobody wants to sit in for an hour, and the reception is fine.
Nothing was wrong with the fragrance and nothing was wrong with the instinct. The rooms were simply never comparable. One is wide and open onto a door that never stops; the other is small and shut. Buying them the same thing was the error, and it is an easy one to make because the shelf sells units rather than volumes.
So the sentence I use is: one oil, two levels, and the second level comes out of the hardware. In most Alkapuri and Akota suites that means Mountain Breeze standing in reception and the meeting room left with whatever crosses the threshold — which, nine times out of ten, is already exactly the right amount. If you take one thing from this page, take the door habit: open between appointments, shut for them. It is free and it does most of the work.
Frequently asked questions
Should reception and the private client meeting rooms use the same fragrance intensity?
No. They should use the same fragrance and two different levels, and the private room is always the lower of the two — usually a third to a half of what reception carries. The reception has several times the air volume and a door replacing that air all day; a closed meeting room has neither, so the same output accumulates there over an appointment.
Should the two rooms at least share the same fragrance?
Yes, and this part is not negotiable. One register across the whole suite, held for as long as you keep it. A visitor who meets Mountain Breeze at the entrance and something else behind the meeting-room door has walked through two different buildings in thirty seconds, and the suite stops reading as one practice.
How do I actually make one room lower than the other?
With hardware, not with a setting. Either put a single source in reception and let the meeting room inherit a trace through the door between appointments, or give the closed room a smaller format of its own — a 50ml bottle with two or three fibre reeds instead of six, placed as far from the chairs as the room allows.
Is it acceptable to leave the private meeting room with no source at all?
It is the answer I give most often, especially under about 150 sq ft with the door shut for an hour. A room with no source of its own is not an unscented room — it holds a faint version of whatever reception is carrying, and that faint version is usually the specification you were trying to buy in the first place.
Can one machine cover both rooms at two different levels?
Not by adjusting it. A machine produces one level across the connected volume it serves, varied only by distance, so turning it down for the meeting room turns reception down at the same moment. What SOSA Vaayu at ₹11,999 does give you is geometry: place it once in the open room, key-lock it, and the closed rooms sit lower because they are further away and behind a door.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the planning advice applies to any brand.Facts verified 5 September 2026 against the live SOSA product pages: the SOSA reed diffusers are alcohol-free, phthalate-free and paraben-free compositions on a heat-stable coconut-derived base, supplied in a refillable glass bottle with six fibre reeds, flipped weekly, with 50ml lasting 6-8 weeks and 130ml lasting 14-18 weeks, tested at 45°C and 85% relative humidity - Mountain Breeze ₹849 / ₹1,349, Morning Freshness ₹749 / ₹1,249, Evening Calm ₹799 / ₹1,299. The SOSA Sukoon (₹1,899) is an ultrasonic cool-mist diffuser covering about 270-320 sq ft for 16-18 hours on the low setting and supplied with three 15ml Hotel Collection fragrances; being ultrasonic, it works by aerosolising water and therefore adds some moisture to the air, which is worth weighing in a warm, high-occupancy room. 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 roughly 75-90 days a fill depending on intensity and run hours, Bluetooth app and onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, DC 12V/1A at 5W (roughly 1.5 units of electricity a month on a ten-hour daily schedule, and tariffs vary), freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification - which are electrical and compliance marks, not medical approval. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment; refill availability should be confirmed with SOSA. 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.

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.
