Am I being told which cleaning product to use? Not at all, and I have no standing to. Which products are acceptable in a diagnostic building is your facilities lead and your lab director to decide, on grounds that have nothing to do with how anything smells. What I can say is that within whatever set they already accept, the fragrance load varies enormously between brands and between variants of the same brand - and that difference is the one variable on this page you are free to move.
What does SOSA sell at this step? Nothing. There is no cleaning product, no floor concentrate and no surface spray in the range, and there is no plan to add one. That is worth stating plainly on a page recommending you spend money before you spend it with me. If after the product trial the room is neutral and simply wants a character, then a Morning Freshness reed at ₹749 or the SOSA Vaayu at ₹11,999 becomes a reasonable conversation.

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 would like to show you the arithmetic rather than assert it, because once it is written down the conclusion is not really arguable. One of these two things is applied by the litre and one by the millilitre.
Quick answers — read this first
Should I change cleaning products before increasing fragrance? Yes, because the cleaning product is by far the larger signal in your building. It is applied wet to every square metre of floor and most surfaces, several times a day, in litres. A diffuser releases a few millilitres into the air over the same period. If your room smells of something you do not want, the odds are heavily on the thing you are applying by the litre, and adjusting the smaller of the two first is working the wrong end of the problem.Am I being told which cleaning product to use?

The short answer
Short answer: Yes. A cleaning product is applied wet to every square metre of floor several times a day, in litres, while a diffuser releases a few millilitres into the air over the same period - so the cleaning product is the larger and more frequent signal by a wide margin. Trial a lower-fragrance option within whatever range your facilities lead already accepts, then decide about fragrance.
The pick: nothing from SOSA at this step - and afterwards, if the room wants a character, a Morning Freshness reed at ₹749 or Mountain Breeze at ₹849.
Next step: send us the labels of what you clean with and we will tell you what a fragrance would be sitting against - ask for a clinic scenting plan.

Straight answer
Should I change cleaning products before increasing ambient fragrance?
Yes, and the arithmetic is not close. Put the two side by side. A floor cleaner is diluted in a bucket and applied wet, to every square metre of your public floor, plus counters, door furniture and washroom surfaces, and in a busy diagnostic centre that happens three or four times a day. Call it several litres of working solution across several hundred square metres, repeatedly, with a fresh wet surface evaporating each time. Now the other side: a reed diffuser releases something like a millilitre a day, and a machine set for a normal commercial level releases a few millilitres, into the air, from one point in the room. The two are not comparable inputs, and the smaller one is the one everybody adjusts first. That is the whole argument, and everything else on this page is detail. There is a second point about frequency. Your cleaning product creates a fresh peak every time it is applied, so the room receives it as a series of strong events distributed through the day. A diffuser produces a low continuous background. When somebody says their centre smells of chemicals, what they are usually describing is the peaks, and a background will not change a peak - it will simply be present underneath it. Now the boundary, and I want to be exact about it. I am not telling you which cleaning products to use. That decision belongs to your facilities lead and your lab director, it is made on grounds that have nothing to do with smell, and a perfumer has no business anywhere near it. What I can tell you is what happens inside whatever range they already consider acceptable, and the answer is that fragrance load varies enormously across that range - between brands, between a concentrate and a ready-to-use dilution of the same product, and often between variants sitting on the same shelf. Some are heavily perfumed and some are close to unfragranced. That variation is the lever you are allowed to pull, and pulling it is free at the point of decision because you were buying a product anyway. Run it as a small trial rather than a switch: one alternative, one area of the building, two weeks, and a written note from whoever is in that area all day. If a lower-fragrance option is acceptable to the people who own that decision, you will have changed the largest smell input in the building without touching a diffuser. And then, only then, ask what the room wants. Often it wants nothing, which is a legitimate and free outcome. If it is neutral and simply characterless, a low dry scent is a reasonable finish: one Morning Freshness reed at ₹749, Mountain Breeze at ₹849, or a SOSA Vaayu at ₹11,999 on a genuinely large floor. SOSA sells nothing at all at the cleaning step, which is worth saying out loud on a page that recommends it. Fragrance is an ambience decision like lighting, seating or signage, it works alongside your cleaning and ventilation rather than instead of them, SOSA products are not medical devices, collection, processing and scan rooms stay unscented, and the clinician's judgement overrides any scenting plan.
Yes. Litres on every surface several times a day against millilitres into the air once - the cleaning product is the larger signal. Move it first, within whatever range your facilities lead accepts.
There is nothing to buy from me at this step and that is the point of the page. Afterwards, a Morning Freshness reed at ₹749 or Mountain Breeze at ₹849 is the usual honest answer.

Nothing here belongs in the product trial. Come back to this section when the cleaning question is settled and the room is neutral rather than noisy - at that point the decision is an ordinary one about volume and traffic.

SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³, about 2,000-3,000 sq ft, at ₹11,999, with run windows, adjustable intensity and a key-lock. Sensible on a large busy floor and unnecessary on a small quiet one.

SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, at ₹25,999 with an 800ml reservoir and programmable schedules. The step up when one Vaayu genuinely cannot hold the public volume.

Three reasons the product wins this comparison
Volume, frequency and position. Each one favours the cleaning product, and together they make the ranking hard to argue with.
1
One
Volume: litres against millilitres
This is the crude comparison and it is the one that decides it. A bucket of working solution spread across a public floor is measured in litres and covers every square metre of the largest surface in the building. A reed releases roughly a millilitre a day from a fixed point, and a commercial machine at a sensible level for a medical building releases a few. Even allowing that most of a cleaning solution is water and that fragrance oils are far more concentrated than a diluted cleaner, the difference in delivered material is not in the same order. If you want to change what a room smells of, changing the input that arrives by the litre is simply where the leverage is.
Tip: Look at what your housekeeping store consumes in a month, then look at how long a 50ml reed lasts. Six to eight weeks against several litres a week tells the whole story.
A Vaayu is a precise, low-output instrument. That is a virtue in a medical building and it is exactly why it cannot outweigh a mop.

2
Two
Frequency: peaks against a background
A cleaning product produces a sharp event. It is applied all at once, the surface is wet, the concentration in the air rises quickly and then falls over the next half hour as the floor dries. Repeat that three or four times a day and the room experiences a series of peaks with quiet stretches between them. A diffuser does the opposite: a steady, low, continuous presence. People almost always describe their complaint in terms of the peaks - the room after the mid-morning clean, the corridor at four - and a background cannot do anything about a peak. It just sits underneath it. Adjusting the continuous thing to solve a problem that arrives in bursts is a category error, and it is the commonest one in this whole subject.
Tip: Ask whoever complains when it is worst rather than what it smells of. If the answer is a time, you are looking at a peak and the diffuser is not involved.
A scheduled Vaayu can at least stay out of the peaks, which is a different and more modest claim than solving them.
See SOSA Vaayu →
3
Three
Position: surfaces against a single point
The cleaning product is on every surface in the room, including the ones people touch and the ones directly under a seated nose. A diffuser is one point source, and its output is diluted across the whole volume before it reaches anybody. That distribution difference matters as much as the quantity: a smell coming off the floor two feet from a child in a pushchair, or off a counter directly under somebody leaning on it, arrives far less diluted than anything from a machine on a wall three metres away. It is also why the smell of cleaning is more noticeable to a person than to somebody standing at the desk, and why the honest test is always to sit where a customer sits.
Tip: Sit in the seat nearest the counter for two minutes after a clean. Nobody who works in a building ever does this, and it settles arguments.
On a large floor an Angaan at ₹25,999 distributes from the air handling rather than from a corner, which improves evenness and changes nothing about this ranking.

The SOSA principle
The input you buy in five-litre containers will always outweigh the one you buy in fifty-millilitre bottles, and the second one is the only one with a salesperson attached.
That asymmetry is why the cleaning question gets skipped, and it is the single most reliable way to spend money on the wrong end of this problem.
How to run the trial
Four steps, none of which involves us. Keep it small and written, in the same spirit as any other change you would make to a working building.
The SOSA plan
A two-week cleaning-product trial, step by step
| The step | What to do, and who owns it |
|---|---|
|
Ask what is acceptable before you ask what smells better
|
Your facilities lead and lab director define the set of products that may be used. That list comes first and it is not a fragrance decision. Everything below happens inside it. |
|
Pick one lower-fragrance option from inside that set
|
One alternative, not three. Compare the labels and, where you can, smell the working dilution rather than the concentrate, because that is what the room will get. |
|
Trial it in one area for two weeks
|
One zone, unchanged routine, everything else held constant. Take a written note from whoever is in that area all day, because they notice the difference you will not. View → |
|
Only then decide about fragrance
|
A quiet room may want nothing, and that is a good result. A neutral, characterless one is a fair candidate for a low dry scent, sized to the public volume. View → |
Why the two smells interfere in the first place is set out in why fragrance clashes with cleaning chemicals, the case for leaving the clean note alone entirely is in should I cover a disinfectant smell with fragrance, and the whole running order sits in what a diagnostic centre should fix first. SOSA makes no health or therapeutic claim of any kind, and no claim that scenting affects how a centre performs commercially.
Two labels, photographed on a phone
Send us what you clean with and we will tell you what any fragrance would be sitting against. We sell nothing at that step.
I am asking you to spend money with a chemicals supplier rather than with me, and the arithmetic is not close enough to make that a difficult recommendation.

For most centres the answer after the trial is a reed at ₹749-₹849, or nothing at all, and both are fine results. SOSA sells no cleaning product of any kind, so there is nothing of ours to buy at the step this page recommends. There is no cold-air refill oil sold today, so the 400ml supplied with a machine is the whole supply available and further refills must be confirmed with SOSA. 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, processing and scan 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 once the trial is done.

A note from Sonal
The reason I keep coming back to this comparison is that it is the only part of the subject where the numbers are obvious and nobody looks at them. Owners will spend an hour choosing between two fragrances and no time at all on the five-litre container that goes over the entire floor three times a day. Both decisions change what the room smells of. Only one of them changes it by much.
I am careful about where my opinion stops. I know what materials smell like and how they behave in a room. I do not know what a diagnostic building needs from a cleaning product, and that judgement sits with people who are qualified to make it. So the version of this advice I am willing to give is narrow: inside the set your own people already accept, ask how heavily fragranced each option is, because nobody usually thinks to.
That leaves this as a page with nothing of mine at the end of it, which is the honest shape for it. 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. Clinical 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
Is SOSA telling me which cleaning products to use?
No, and it would be wrong of us to. Which products are acceptable in your building is decided by your facilities lead and your lab director on grounds that have nothing to do with smell. The narrow point here is that within whatever set they accept, the fragrance load varies a great deal, and that is a question worth asking.
How much difference does a lower-fragrance cleaning product actually make?
In the cases I see, more than any diffuser setting. You are changing an input applied in litres over every surface several times a day. A reasonable expectation is that the peaks after each clean become noticeably shorter and lower, which is usually the whole complaint.
Does SOSA make a cleaning product?
No. There is no floor concentrate, surface spray or cleaning product of any kind in the range, and no plan for one. This is a step where we have nothing to sell you, which is precisely why it is worth reading our opinion on it.
How should I run the comparison fairly?
One alternative product, one area of the building, two weeks, and nothing else changed in that period. Take a written note from whoever works in that area all day rather than judging it yourself on a visit, because they will notice the difference and a visitor will notice the novelty.
What if the lower-fragrance option is not acceptable to my facilities lead?
Then it is not an option, and that is the end of it. Their decision comes first every time. In that case go back to the free levers: the hour of the heaviest clean, the airing period afterwards, and keeping any fragrance low enough that the two are not competing.
