Why does the arrival not need a higher level? Because a threshold works on contrast rather than on quantity. Someone stepping in from a hot forecourt or a corridor into a conditioned room registers the change, and a modest level is a perfectly clear change. Raising the level does not make the threshold more legible; it just raises the floor everyone is standing on for the next two hours. Once the nose adapts — about twenty minutes, in most people — the only thing a high setting is still doing is being present when it is no longer wanted.
Should this room be in the plan at all? Sometimes it should not, and you can settle that by watching your own table for a fortnight. If cloth is opened at ten and still spread out at four, the room is functionally part of the sample area and belongs outside the plan, because the goods are the product and the product should reach the buyer as the mill made it. If lengths come and go while the real work happens elsewhere, it is an ordinary meeting room with an unusually long dwell, and that is what this page is about.

Facts verified 16 September 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 90+ days 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), freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. Being waterless, it adds no moisture and leaves no residue on surfaces or equipment. 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. The SOSA Meenar (₹38,500) is the largest machine in the range, quoted for roughly 12,000-18,000 sq ft of HVAC-connected space. Ambient scent is an interior and brand-experience decision: it works alongside proper ventilation, housekeeping and source control and is not a substitute for any of them.

Much lower than you think, and the reason is the two hours rather than the room. A level chosen so that a buyer notices something pleasant on the way in is a level they will be quietly enduring by half past three, and the difficulty is that nobody in the room will mention it.
Quick answers — read this first
How strong, in practical terms? A fraction of what the machine can do. Work the volume first: a 480 sq ft meeting room under a 3.2 m slab is 480 × 3.2 × 0.0929, about 143 m³, against a unit rated to 1000m³ — so you are asking for something in the region of a seventh of its capability. That sounds absurdly low until you remember the exposure. Thirty seconds at a threshold can carry a level that two hours cannot, and this room is the two-hour room. Set it for the end of the meeting and let the beginning look after itself.Why does the arrival not need a higher level? Because a threshold works on contrast rather than on quantity. Someone stepping in from a hot forecourt or a corridor into a conditioned room registers the change, and a modest level is a perfectly clear change. Raising the level does not make the threshold more legible; it just raises the floor everyone is standing on for the next two hours. Once the nose adapts — about twenty minutes, in most people — the only thing a high setting is still doing is being present when it is no longer wanted.
Should this room be in the plan at all? Sometimes it should not, and you can settle that by watching your own table for a fortnight. If cloth is opened at ten and still spread out at four, the room is functionally part of the sample area and belongs outside the plan, because the goods are the product and the product should reach the buyer as the mill made it. If lengths come and go while the real work happens elsewhere, it is an ordinary meeting room with an unusually long dwell, and that is what this page is about.
The short answer
Short answer: Set it for hour two rather than minute one. A two-hour review is the longest exposure anyone in the building has, so the level that works there becomes the ceiling for every other room. In practice that means a small fraction of a machine's capability — a 480 sq ft room at 3.2 m is about 143 m³ against a unit rated to 1000m³ — run on a schedule and locked, so nobody raises it once their own nose has adapted.
The pick: one SOSA Vaayu at ₹11,999 serving the meeting room's volume at roughly a seventh of capacity, on a timer that opens before the meeting and closes after it.
Next step: send the meeting-room plan with the ceiling height and a note of how long cloth actually stays on the table, and the level gets set against the real dwell time — ask for a scenting plan.

Straight answer
How strong should the fragrance be in a room where a buyer sits for two hours?
Lower than almost anybody's instinct, and the governing number is the two hours rather than the square feet. Here is the mechanism. The nose adapts to a constant ambient level within about twenty minutes — that is ordinary human physiology and it applies to your buyer, to your merchandiser and to you. So for the first twenty minutes of a long meeting the room's air is perceptible, and after that it is not, for anybody who has stayed in it. What does not stop is the exposure itself. The material is still arriving in the air at the same rate, it is still being noticed by anyone who comes in from outside, and it is still present in a way that becomes wearing across a second hour even though nobody can consciously report it any more. That asymmetry is why a level chosen to be pleasant at the door is a level being endured by half past three, and why nobody in the room will say a word about it: the people who could judge it have adapted, and the one person who has not — the buyer — is a guest and will not raise it. So set the room for hour two. In practice that means a small fraction of the machine's capability. Do the volume honestly: square feet × ceiling height in metres × 0.0929, so a 480 sq ft meeting room under a 3.2 m slab is about 143 m³. Against one SOSA Vaayu at ₹11,999 rated to 1000m³, that is somewhere around a seventh of capacity, and it is the correct answer rather than a timid one. The arrival, meanwhile, needs nothing extra. A threshold works on contrast: someone moving from a warm corridor into a conditioned room registers the change itself, not the quantity, so a modest level is already a clear signal and a loud one is merely loud. Two further points. This room sets the ceiling for the whole building — whatever level works across two hours is the highest level you should be running anywhere in the plan, because no other room in a textile building exposes anyone for as long. And the room may not belong in the plan at all: if lengths are opened at ten and still on the table at four, treat it as part of the sample area and leave it alone, because the goods are the product and the product should reach the buyer as the mill made it. Ambient fragrance is an interior and brand-experience decision that works alongside your ventilation and housekeeping rather than instead of them, and nobody can promise you it moves a business number. The concession is real: setting for hour two means the visitor who comes in for fifteen minutes gets less than they might have, and I am willing to trade that.
Set it for the second hour, which is far lower than instinct suggests — around a seventh of the machine for a 143 m³ room. The threshold takes care of itself through contrast, and this room sets the ceiling for the building.
One SOSA Vaayu at ₹11,999 is specified here for its low end rather than its ceiling: it holds a small output steadily for hours instead of surging. Waterless, no added moisture, no residue on surfaces, 400ml tank at 90+ days, key-lock, about 5W.

Why the low settings are the ones that matter here
A long meeting is decided at the bottom of a machine's range
The machines, and why the low end is what you are buying
In a long-dwell room the top of a machine's range is irrelevant and the bottom of it is everything. What matters is whether a small output can be held steady for three hours without surging or fading, and whether the number can be locked so it survives whoever comes in early on a slow morning.

Three things a two-hour room changes
Adaptation, the ceiling this room sets for everything else, and the schedule that makes both survivable. Nothing here is about which fragrance; all of it is about how much and when.
1
One
Adaptation, and why nobody in the room can judge it
Within about twenty minutes of sitting in a constant ambient level, a person stops registering it. Your buyer stops. Your merchandiser stopped an hour earlier. You stopped before the meeting began, because you walked through reception on your way in. This produces a very particular failure: the only people able to judge the room are the ones who have just arrived, and the only people who adjust the dial are the ones who have not just arrived. So the level creeps upward across a year, one reasonable adjustment at a time, and every one of those adjustments was made by somebody who genuinely could not smell it any more. In a lightly occupied building there is also nobody to push back. A retail floor gets a complaint by lunchtime. A buyer meeting room gets a polite guest who will never tell you, and a team who stopped noticing in March.
Tip: Judge the room by walking out for ten minutes and coming back in. That is the only honest reading anybody inside the building can take.
This is why the Vaayu is specified here for its low settings and its lock rather than for its coverage figure.

This room sets the ceiling for the whole plan
Run through the dwell times in a textile building and the ranking is clear. A buyer crossing the entrance is there for half a minute. Someone waiting in reception has five to fifteen minutes. A meeting or a review runs one to three hours, and in this trade often the longer end of that. Nothing else in the building exposes a visitor for as long. That makes this room the governing case: whatever level is comfortable across two hours is the highest level worth running anywhere in the plan, because a level that is wearing here will also be wearing in reception for anybody who waits a while, and the reception is meant to be the easy room. Working from the longest dwell downwards is also the only method I know that produces a building where nothing surprises anyone. Working upward from the entrance produces a building tuned for a moment that lasts thirty seconds.
Tip: Write the dwell times of your four main rooms on one line. The longest one is the number the whole building should be set from.
If reception and the meeting room share air, they share a number too — and that number is the one this room can tolerate, not the one the entrance would enjoy.

The schedule does what the dial should not
Once the level is low and fixed, the remaining control is time, and it is the one worth using. Open the run window an hour before a meeting so the volume has settled rather than arriving in a rush; close it when the meeting ends rather than letting it run to six. Do not let it run through a closed weekend, which is a quiet waste and produces a Monday morning nobody planned. And do not use the timer as a way of delivering a higher level briefly, which is the compromise people reach for once they have accepted that the dial should stay low — a burst before the buyer sits down is exactly the shape of thing a nose notices and then spends an hour adapting to. Steady and small, opening early, closing on time. That is the whole regime, and in a building where appointments are set weeks in advance it is easy to administer.
Tip: Set the run window from the diary, not from office hours. This trade knows three weeks ahead who is coming and when.
Lock the Vaayu, write the number and the window on a card inside the cupboard door, and give one person the key. That is what keeps hour two honest.

The SOSA principle
In any building, the longest exposure sets the ceiling for every other room. In a textile company that is the buyer review — two hours or more, far beyond a reception wait and a world away from a thirty-second arrival — so the whole plan should be set from the room people stay in rather than the room they walk through.
And the trap that follows: the people best placed to judge that room have adapted to it within twenty minutes, and they are also the only people who can reach the dial.
The same room, hour by hour
Register is a separate decision, and for this trade the argument for something unrelated to cloth matters more here than anywhere, because a long meeting is where a sweet or literal register becomes tiring first. The table below is about time.

| When in the meeting | What the room is actually doing |

Twenty minutes in — adaptation
|
Everyone in the room has stopped noticing, including the buyer. This is where the instinct to raise the dial appears, and where a key-lock earns its keep. Nothing has faded; the room has simply been absorbed. View → |
|
Hour two — the governing case
|
Exposure has continued even though perception stopped. A level set for the doorway is now being endured rather than enjoyed, and nobody will say so. Set the machine for this point in the meeting and everything earlier follows. |
|
Cloth still on the table at four o'clock
|
If that is your normal pattern, the room is functionally part of the sample area and belongs outside the plan entirely — no machine, no lower setting. The goods are the product, and the product reaches the buyer as the mill made it. |
Whether this room belongs in the plan at all is settled in the four rooms ranked by goods-hours, which is the page to read before you buy anything for it. The level you land on here becomes the ceiling for the rest of the building, which matters most when a company runs two addresses — one register, two settings works that through. And what neutral means in a sample area covers the room next door. SOSA makes no claim that ambient fragrance affects enquiries, orders, buyer decisions or any commercial number.
Set against your own dwell time
Send the room's dimensions, the ceiling height and an honest note of how long cloth stays on the table.
Set the room for the second hour and the first minute takes care of itself. Set it for the first minute and the second hour becomes something your buyer quietly endures.

If cloth lives on that table through the working day, the honest answer is nothing at all in this room, and a Mountain Breeze reed at ₹849 in the reception outside it is as far as the plan goes. Ambient scent is an interior and brand-experience decision, with no claim that it affects enquiries, orders, buyer decisions or any commercial number — nobody can promise that. It works alongside ventilation, housekeeping and source control rather than replacing them, and it does not remove, settle or reduce dust. The sample area, the packing bay, the godown, the mill floor and any area governed by a customer's own audit requirement stay unscented, and that protocol decides, not us. SOSA publishes no bulk pricing, no minimum order, no custom branding, no lead time, no installation and no maintenance terms; a multi-site question goes to our contact page with nothing promised. Ask for a scenting plan and the level gets set against your real dwell time.

A note from Sonal
I sat through a full buyer review once, at the invitation of an owner who wanted to know why his meeting room had been described by a visitor as strong. For the first quarter of an hour I thought the room was fine. By the second hour I understood the complaint completely, and by then I could not smell anything at all — which is precisely the problem, because neither could anyone else in the room, and the setting had been chosen by someone standing in the doorway at nine in the morning.
We reduced it to roughly a seventh of where it had been and moved the run window an hour earlier so the volume had time to settle. The next visitor described the room as comfortable, which is the word I am always hoping for, and the owner told me he could no longer detect anything from the doorway. That is not a fault. It is the room being set for the people in it rather than for the person arriving at it.
The trade-off is genuine and I will not hide it: a visitor who looks in for ten minutes now gets less than they might have. We make no claim that ambient fragrance affects enquiries, orders, buyer decisions or any commercial outcome, and nobody can honestly give you a figure. What a properly set long room does is stay comfortable for as long as somebody has to sit in it. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
If nobody can smell it after twenty minutes, why not simply set it higher?
Because perception stops and exposure does not. The material keeps arriving at the same rate for the whole two hours, so a level that was pleasant at the door is still being delivered at half past three — the room has just lost its ability to report it. Raising the dial to restore a sensation you have adapted to is the single commonest mistake in long-dwell rooms, and a key-lock is the practical cure.
Does the buyer not deserve a noticeable welcome when they walk in?
The welcome happens through contrast, not through quantity. Stepping from a warm corridor into a conditioned room is already a clear change, and a modest level marks it perfectly well. Setting the room so the first minute is impressive means paying for it with the following hundred and nineteen, and the person paying is the guest who will never say anything about it.
How do I know what a seventh of capacity actually is on the machine?
Start at the lowest usable setting rather than working down from the middle, leave it for three days, and judge it by walking out for ten minutes and coming back in. Do the volume sum first so you know roughly where you should land: 480 sq ft at 3.2 m is about 143 m³ against a unit rated to 1000m³. Then write the number on a card and lock it.
Should the reception outside run at the same level as this room?
It can run at the same level or lower, never higher, because this room sets the ceiling for the building. If the two share air with no door between them, they are one volume and one number anyway, and that number is the one a two-hour meeting can tolerate rather than the one a thirty-second entrance would enjoy.
Does a comfortable meeting room help a long negotiation go better for us?
I have no basis for telling you that and would not try. There is no claim here that ambient fragrance affects an enquiry, an order, a buyer's decision or any commercial number. What a correctly set room does is avoid becoming one more small thing a visitor has to tolerate across an afternoon, which is a modest and defensible thing to buy.
