Where exactly should the source go? Deep - roughly one and a half to two metres past the entrance threshold, out of the door draught, and as far from the corridor mouth as the room sensibly allows. Wall-mounted at about a metre up is better than a console table by the passage. The instinct is to put it near the middle of the plan, which usually turns out to be the exact spot where reception air is being drawn toward the back of house.

What if there is no corridor between reception and the cubicles? Then be honest about what you have: one volume with a partition in it, not two zones.

A curtain is not a boundary, and a doorway with no door is a gap that both rooms share whatever the plan calls them.

Facts verified 5 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 hospitality decision: it works alongside proper ventilation, cleaning and clinical protocol and is not a substitute for any of them, it is not a medical device, and SOSA makes no health, therapeutic or treatment claim of any kind and no claim that fragrance affects bookings, retention or spend. CE, RoHS and SGS are electrical and compliance marks, not medical approval. 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.
Yes, and I want to spend this page on the mechanism rather than the permission. Three ordinary features of your floor plan do almost all of the work, and none of them appears on an invoice.
Quick answers — read this first
Can I scent reception and still keep the collection side neutral? Yes, in most layouts, and the things that make it work are already in your building. A corridor between the two acts as a buffer volume. A door that actually closes acts as a boundary. And distance does the rest, because output falls away as it travels and mixes. Place your single source deep in the public zone rather than near the corridor mouth, put nothing behind the boundary, and the separation looks after itself without any special equipment.Where exactly should the source go?

The short answer
Short answer: Yes, in most pathology layouts. The separation is produced by three things you already own - a corridor acting as a buffer, a door that genuinely closes, and distance from the source to the boundary. Place one source deep in the public zone, away from the corridor mouth, and put nothing behind the door at any setting. Where cubicles open straight onto the waiting seats, run much lower everywhere instead.
The pick: one Morning Freshness reed at ₹749 placed deep in the waiting area, or a wall-mounted SOSA Vaayu at ₹11,999 where the public volume is large.
Next step: send the plan marked with your doors and we will suggest a position rather than a product - ask for a clinic scenting plan.

Straight answer
Can I scent the pathology reception and keep the sample-collection side neutral?
Yes, in most layouts, and the useful part of the answer is that you are not buying the separation - you already own it. Three ordinary features of a pathology floor plan do nearly all of the work. The first is the corridor. Almost every centre has some passage between the waiting seats and the working rooms, and that passage is a buffer volume: whatever reaches it from reception is already diluted, and it fades further as it travels. The single most common mistake is to treat the corridor as a room that needs its own source. It does not. A buffer with a source in it stops being a buffer. The second is the door. A door that actually closes, with a working closer and nothing propping it open at nine in the morning, is worth more than any change of setting you could make out front. This is unglamorous and it is where the real variance lies between centres - the same floor plan with the doors shut and with the doors wedged behind a trolley behaves like two completely different buildings. The third is distance, and distance is a placement decision rather than a product one. Put the single source deep in the public volume: about a metre and a half to two metres past the entrance so it is out of the door draught, away from the corridor mouth, wall-mounted at roughly a metre up rather than sitting on the console table that happens to be next to the passage. The prettiest spot in a reception is very often the worst one for this, because it is on the path along which reception air is drawn toward the back. Then the rule that no amount of placement replaces: nothing goes behind the boundary at any setting. Not a smaller bottle, not a lower dial. Those rooms are specified by your lab director and your facilities engineer, and we do not put a fragrance source in a space where samples are taken - that is their call, not ours, and we make no assertion about it in either direction. Finally, the concession this page owes you. If your collection cubicles open straight onto the waiting seats, with a curtain rather than a door and no corridor between them, then you have one volume with a partition in it. In that layout the honest answer is a much lower level everywhere, or nothing at all. Fragrance is an ambience decision like lighting, seating or signage, it works alongside your ventilation, cleaning and laboratory protocol rather than instead of them, SOSA products are not medical devices, and the clinician's judgement overrides any scenting plan.
Yes. A corridor buffers, a closing door bounds, and distance dilutes - place the single source deep in the public zone, away from the passage, and put nothing behind the boundary at any level.
Placement matters far more than product here, but the product itself is simple: a Morning Freshness reed at ₹749 set deep in the waiting area, or a wall-mounted SOSA Vaayu at ₹11,999 in a large one.

Why mounting position matters more than model
Deep in the room, high on the wall, off the air path
Machines you can place deep and mount high
If your public volume is small, skip this and buy the bottle - placement is the whole lesson and it applies to a reed just as much. Where a machine is warranted, the thing worth paying for is the freedom to put it somewhere sensible: wall or HVAC mounting, a small footprint and no water tank that has to sit near a socket and a sink.

The three things doing the work
Not one of these is a product feature. Two of them are already in your building and the third is a decision you make with a tape measure.
1
One
The corridor is a buffer, so leave it empty
A passage between the public zone and the working rooms is the most useful thing on your plan for this purpose, and the way to use it is to do nothing to it. Whatever drifts in from reception is already thinned by mixing, and it thins further along the length of the corridor, so the far end is naturally the quietest point in the building. Owners often want to add a small source there because the corridor feels neglected. That single decision converts your buffer into a second source, sitting closer to the boundary than the first one, which is exactly backwards. If the corridor feels bare, put something on the walls. A corridor that fades toward the working end is not a fault to be corrected - the fade is the entire point of having one.
Tip: Stand at the far end of the corridor with the doors shut. Whatever you can just barely detect there is the correct amount.
One Vaayu serving the public volume beats a main unit plus a small extra by the passage, which competes with it rather than adding to it.

Two
A door that closes beats any change of setting
This is the cheapest and least popular finding I give people. Two centres with identical plans behave completely differently depending on whether the boundary doors are actually shut, and in a busy morning they are very often not - propped with a wedge, held by a trolley, or fitted with a closer that gave up a year ago. Before you adjust anything about fragrance, walk the boundary at nine in the morning and look at every door between the waiting seats and the working rooms. Fix the closers, remove the wedges, and if a door is being propped because staff are carrying things through it constantly, that is a workflow problem worth solving on its own merits. A working door is the boundary; everything else on this page is refinement.
Tip: Do the walk at your busiest hour, not at eight in the evening when the building is calm and every door is obediently shut.
Where a machine is in use, a scheduled Vaayu at least lets you take the source out of the equation entirely during the busiest hour at the boundary.

Three
Placement is distance, and distance is free
Output falls away with distance and mixing, so where you put the single source decides more than which source you bought. Three rules cover most receptions. Put it about one and a half to two metres past the entrance so the door draught is not exporting it to the street. Put it as far from the corridor mouth as the room allows, because that mouth is where reception air is being drawn toward the rest of the building. And get it up off the floor to roughly a metre, on a wall rather than on a table, so it is not aimed at the head height of somebody sitting three feet away. The best-looking position - the console by the passage, the counter end - is almost always the worst-performing one, and moving the source is free.
Tip: Before buying anything, move the bottle you already have to the far corner for a week. Very often that is the whole fix.
On a large split floor, an Angaan fed into the public-side duct work gives you distance by design rather than by furniture arrangement.

The SOSA principle
Separation between a public zone and a working one is a geometry you already paid for when the building was fitted out. The only way to lose it is to add a second source.
Corridor, door, distance. Two are on your drawing and the third is a tape measure, and none of the three is on a price list.
Placement, boundary by boundary
This is a positioning table rather than a product table. Work through it with the plan in front of you and a pen.
The SOSA plan
Where the source goes on a split pathology plan
| Part of the plan | The placement decision |
|---|---|
|
Deep in reception and waiting
|
The one source lives here: 1.5-2m past the threshold, wall-mounted around a metre up, furthest from the corridor mouth. View → |
|
The entrance draught and the doorway itself
|
Nothing here. A source at a cycling door exports most of its output to the street and reads as invisible inside the room. |
|
The corridor to the working rooms
|
Left empty on purpose. It is the buffer, and its fading far end is the mechanism rather than a shortfall. View → |
|
Cubicles, bench and processing rooms
|
Nothing, at any setting. Those rooms are specified by your laboratory and we place no source in a space where samples are taken. |
If the worry is timing rather than position, the run-window approach is set out in how to stop reception fragrance drifting into the back rooms, the boundary rule itself is in should blood-collection areas be kept fragrance-free, and if your air handling is shared across the floor, read how HVAC airflow should affect placement before buying anything. SOSA makes no health or therapeutic claim of any kind, and no claim that scenting affects how a centre performs commercially.
Position first, product second
Mark your doors and your corridor on the plan, send it over, and the first thing you will get back is a cross on a wall.
The separation you are trying to buy is already drawn on your floor plan. All you have to do is stop putting things in the corridor.

Fragrance is an ambience decision like lighting or signage, with no health, therapeutic or clinical claim of any kind, and no claim that it affects how a business performs. It works alongside your ventilation, cleaning and laboratory protocol, never instead of them, and SOSA products are not medical devices. Collection, bench and processing rooms stay unscented, staff must be able to switch the source off in seconds, and the clinician's judgement overrides any plan. Ask for a clinic scenting plan and we will mark a position on your drawing.

A note from Sonal
When somebody sends me a pathology plan with this question on it, the first thing I look for is not the square footage. It is whether there is a corridor, and whether the doors off it are real doors. Those two features decide more than any product I could recommend, and they are usually already there. It is an odd sales conversation to have - most of my answer is a description of what the building is doing on its own.
The second thing I look for is where the existing bottle is sitting, if there is one, and it is nearly always in the worst place available: on the counter by the passage, or on a console table right inside the door. Moving it takes a minute and costs nothing, and in a fair number of centres that single change is the difference between a room that reads as looked after and a room where the smell seems to be coming from the corridor.
So yes, you can do both, and the mechanism is geometry rather than hardware. We make no health, therapeutic or clinical claim of any kind, and no claim that scenting affects how a centre performs commercially. Fragrance is an ambience decision, like lighting or seating. Collection and processing rooms stay unscented, and the clinician's judgement overrides any plan. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Can I scent reception while keeping the sample-collection side neutral?
Yes, in most layouts. The corridor acts as a buffer, a door that closes acts as a boundary, and distance from the source to that boundary does the rest. Put one source deep in the public zone, away from the passage, and put nothing at all behind the door at any setting.
Should I put a small source in the corridor as well?
No. The corridor is doing its job by being empty. Adding a source there puts output closer to the boundary than your main one and turns a buffer into a second gradient. If the passage feels neglected, that is a decorating problem rather than a fragrance problem.
Where is the worst place to put the source?
In the entrance draught, or on whatever surface happens to sit at the mouth of the corridor. The first exports most of the output to the street each time the door cycles; the second places it on the path along which air is drawn toward the back of house. Both are common, and both are free to correct.
Do I need a second machine to hold the boundary?
Almost never, and a second unit in the same connected volume usually makes things worse rather than better. Two sources in one space produce competing gradients instead of combined coverage. If the far end of your waiting area is quiet, that is normal and acceptable, and a second machine is the expensive way to discover it.
What if the cubicles open directly onto the waiting seats?
Then treat the whole thing as one volume and run it much lower, or leave it unscented. A curtain is not a boundary and a doorway with no door is shared air. I would rather say that plainly than sell you a machine that cannot deliver the separation you are asking about.
