Founder Diaries · Commercial Scent Marketing
Why is an evasive answer so damaging? Because of what the buyer is half-asking. A question about a smell in a property is the one question where deflection confirms the worst reading of it. If you say you cannot smell anything, or change the subject to the view, or say vaguely that it is probably the new woodwork, the buyer now has two data points: there is a smell, and the agent did not want to discuss it. That combination is exactly the shape of a cover-up, and it is a much worse position than you were in ten seconds earlier. Buyers are not offended by a prepared property. They are offended by an agent who seems to be managing them.
What must I never do with that answer? Never use it to deflect from a real property issue. If the buyer's question is actually about a musty note, a drain smell, a damp patch or cigarette smoke, that is a different question wearing similar words, and answering it with a sentence about your diffuser is dishonest. Listen to which question is being asked. If there is a genuine problem, it is a matter for disclosure and repair, not presentation - say what you know, say what is being done about it, and do not let the fragrance stand in for an answer. The second thing never to do is attach a benefit to it: describe what you did, never what it is supposed to achieve.

Facts verified August 2026: Ambient scent research consistently associates pleasant, congruent scenting with improved evaluations of a space and its service, longer dwell time and stronger brand recall at moderate effect sizes; congruence (scent matching the setting) and gentle intensity outperform strong scenting in replicated studies, and no scent effect survives poor ventilation, poor cleaning or poor indoor air quality. Olfactory memory is unusually durable: scent-linked brand memories persist and retrieve for years, which is the mechanism behind signature scents. Staff exposure is the design constraint, since employees breathe the fragrance for full shifts: whisper calibration, locked settings and sensitivity accommodations are standard practice, and healthcare and wellness settings call for extra restraint.

A buyer stops in the passage, sniffs once and says it - what is that, it smells nice. You have about two seconds to answer and the answer matters more than the fragrance ever did, because a question about smell is never purely a compliment. Somewhere behind it is the other question, the one nobody asks directly: is there a reason this flat smells of something. Answer the first one truthfully and the second one dissolves. Answer it evasively and you have just created the suspicion you were trying to avoid.
Quick answers — read this first
What should I say when a buyer asks why the flat smells nice? Tell them the truth, in one unhurried sentence: we prepare every property before a viewing - the flat has been opened up and aired this morning, it has been cleaned, and there is a light fragrance running. That is the complete answer and it needs no follow-up. It works because it is true, because it is boring, and because it tells the buyer the thing you actually want them to know, which is that somebody took care of this property before they arrived. If they want to know what the fragrance is, tell them that too. There is nothing in the honest version of this that costs you anything.Why is an evasive answer so damaging?

The short answer
Short answer: Answer the true way: we prepare every property before a viewing, the flat has been aired and cleaned this morning, and there is a light fragrance running. One sentence, no follow-up needed. Evasion is the fastest way to make a buyer suspicious, because a deflected question about smell reads exactly like a cover-up. Never use the answer to deflect from an actual property issue - musty, damp, drains or smoke are disclosure and repair questions, not presentation ones. If a buyer says it is too strong, switch it off immediately. Vaayu Rs 11,999, reeds from Rs 749, registers from Rs 299. WhatsApp +91 96192 18531.

In this guide
Every customer-facing space hosts two audiences at once: the customer who forms an opinion in a single visit, and the staff who breathe that air for eight hours. Commercial scenting serves both with one move - a single refined fragrance, held evenly from the entrance to the far end of the floor, running on a schedule nobody has to remember. Customers experience it as "this brand has itself together"; the team gets premises that smell composed from opening to close.

Straight answer
A buyer asked me why the flat smells nice. What is the right thing to say?
Say the true thing, and say it without pausing first. 1. The answer. "We prepare every property before a viewing. It has been opened up and aired this morning, it has been cleaned, and there is a light fragrance running." That is the whole answer. It is honest, it is unremarkable, and it tells the buyer somebody took care of this flat before they walked into it - which is exactly the impression worth giving. 2. Do not hesitate. The pause does more damage than any wrong sentence. A two-second gap before an answer about a smell is read instantly, and it is read as calculation. 3. Point at the machine if they ask. There is nothing to hide and hiding it is what makes it look like a trick. A small unit standing on the console is a piece of presentation equipment, like the lights being on and the curtains being open. 4. Never attach a benefit. Describe what you did, not what it is meant to do. "It makes the flat feel bigger" or "buyers respond better" turns a straight answer into a sales line and invites the buyer to start resisting you. 5. Listen to which question is being asked. "Why does it smell nice" and "what is that smell" are different questions. If the second one is about a musty note, a drain, damp or smoke, your diffuser is not the answer to it, and using it as one would be dishonest - that is a disclosure and repair matter, and this page says so plainly. 6. If they say it is too strong, switch it off. Immediately, without defending it, and open a window. Same if anyone mentions asthma or a fragrance sensitivity. The too-strong page covers the recovery. The equipment that makes this easy is the equipment you can turn off in one tap from your pocket - a SOSA Vaayu (₹11,999, waterless, app and timer, mains powered) - or a reed from ₹749 you simply carry out of the room. Registers from ₹299. WhatsApp +91 96192 18531. Made in India; a portion of every order supports girl-child education through Nanhi Kali.

The true answer, and why nothing else works
Three things: what the buyer is really asking, why every evasive answer makes it worse, and the one situation in which this answer must never be used.
1
The question
There are three buyers asking this, and one true answer serves all of them
When a buyer asks about the smell in a flat, they are one of three people, and you usually cannot tell which from the tone. The first is simply appreciative: the place feels pleasant, they noticed, and they are making conversation in a passage while you unlock the second bedroom. The second is checking. Not accusing - checking. They have seen eleven properties this month and at least one of them had something under the air freshener, and they have learned to ask. The third is neither: they have a fragrance sensitivity, asthma or a migraine history, and what sounds like curiosity is actually them working out whether they are going to be able to stand in this flat for twenty minutes. The remarkable thing about the honest answer is that it is the correct answer for all three. The appreciative buyer hears that the property was prepared, which is what they were half-complimenting anyway. The checking buyer gets a direct, unbothered response with nothing withheld, which closes the question rather than opening it. And the sensitive buyer gets the information they actually needed, immediately, along with the obvious next move, which is that you turn it off and open a window without making them ask twice. No other answer serves all three, and since you cannot identify which one is standing in front of you, the true answer is not merely the ethical choice. It is the only reliable one.
Tip: you cannot tell which of the three buyers is asking, which is why only the true answer works on all of them.
2
The failure
Every evasive version makes the situation worse than saying nothing
Run through what brokers actually say when caught off guard, and watch each one fail. "Is there a smell? I cannot smell anything" - the buyer knows there is, so you have just told them either that you are lying or that you have been in here long enough to stop noticing, and the second one raises the question of how long that is. "Oh, it is probably the new polish on the woodwork" - an invented attribution, and if the buyer comes back for a second viewing on a day you have not set up, the flat smells different and your explanation has quietly collapsed. "The owner must have sprayed something" - you have put a lie in the owner's mouth and made the fragrance sound accidental, which is worse than making it sound deliberate. And the worst one, which is not a sentence at all: the pause. Two seconds of visible thinking before you answer a question about smell tells a buyer more than anything you say afterwards, because people are extremely good at spotting a constructed answer and this is the exact context in which they are looking for one. The underlying mechanics are simple. A question about smell in a property is already adjacent to suspicion, however friendly the tone. Deflection is what suspicion is looking for. The true answer is the only response that does not feed it, and it has the additional advantage of being effortless: you never have to remember what you told which buyer, because you told all of them the same thing, which is what happened.
3
The line
The one situation where this answer must never be used
Here is the boundary, and it is absolute. If the smell the buyer is asking about is not your fragrance - if it is a musty closed-up note, a drain, a damp corner, old cigarette smoke, a kitchen, something from the shaft or the neighbour's flat - then you must not answer with a sentence about the preparation you did. It would be technically true and functionally a lie, and it uses an honest sentence to walk a buyer away from a real property issue. That is the line this bank will not cross and neither should you. In practice, telling the questions apart is easier than it sounds, because the buyer's face tells you: "why does it smell nice" comes with an open expression and "what is that smell" comes with a slight frown and a second sniff. When you get the second one, answer that question and only that question. Say what you know. If it is a known issue, say what is being done about it and who is doing it. If you do not know, say you do not know and that you will find out, then find out. Any genuine problem - damp, a leak, drainage, smoke damage - is a matter for disclosure and repair, not presentation, and no fragrance at any level and no machine at any price belongs in that conversation. The sequence for a property that genuinely smells stale is on the musty listing page: open it up and ventilate, clean, find and fix the source, and only then think about scenting. Layering fragrance over a live problem does not produce a better smell. It produces a third, stranger smell that buyers read accurately, and it puts you on the wrong side of a conversation you cannot win later.
Tip: a true sentence used to walk a buyer away from a real defect is not an honest answer - it is a better-disguised dishonest one.
The SOSA principle
The honest answer is not the safe compromise here. It is the only answer that works - because a deflected question about a smell is the fastest way to make a buyer suspicious.
We prepare every property we show; it has been aired and cleaned, and there is a light fragrance running. One sentence, said without pausing, with no benefit attached.

The SOSA commercial edit
Whatever your business sells, the system logic is the same: one signature, sized to the space, scheduled so it never depends on anyone's memory. A single small room or a consultation corner can sit happily on reeds with no power at all; a customer-facing floor wants the Vaayu; a venue or a flagship wants HVAC. Every SOSA system is supported from India, and the Hotel Collection blends - SOSA's own hotel-inspired interpretations - run across the powered ones. A portion of every order supports girl-child education through Nanhi Kali. Here is the full commercial range.

Honest notes for business owners: scenting compounds a well-run premises and rescues nothing. Ventilation, air-conditioning and cleaning come first, and fragrance never substitutes for hygiene or air quality - if the air is stale, damp or smoky, fix that at the source before any scent goes in. The people most exposed to the fragrance are not your customers but your STAFF, who work eight-hour shifts in it, which is why whisper calibration and locked settings are standard on every SOSA commercial install, and any staff sensitivity report should be treated as a recalibration signal rather than a complaint. Healthcare and wellness spaces need extra restraint: keep scenting to reception and circulation areas, never treatment rooms, and the practitioner's judgement overrides anything in this guide. The Hotel Collection scents are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house, not affiliated with or endorsed by any hotel brand. Ultrasonic systems use the water-based Hotel Collection fragrance; the Vaayu and HVAC systems run waterless nebulising oil - the formats are not interchangeable. WhatsApp consult: +91 96192 18531.

A note from Sonal
I have walked into jewellery showrooms lit like museums, bridal boutiques with hand-embroidered walls, furniture floors styled down to the last cushion, clinics with better art than most galleries - and in almost every one of them, the air was an afterthought. Floor polish, packaging cartons, the phenyl from the morning mopping, the workshop or the loading bay drifting forward. The one thing every customer takes in before they see anything is the thing most businesses leave to chance.
I trained at ISIPCA in Versailles, where the world's scent-marketing perfumers learn the craft, and what I build for Indian businesses is the same architecture the global hospitality brands use, whatever you sell: one signature, sized to the space, run on a schedule - so the scent is as reliable as your lighting. A consultation corner may only need reeds; a full floor needs the Vaayu; a venue needs the HVAC systems. If you want it applied to your specific premises, message us on WhatsApp at +91 96192 18531 with the type of space and its approximate size - I read those descriptions myself.
Everything is made or assembled for Indian conditions, supported from Pune - and a part of every order funds girl-child education through Nanhi Kali. Your brand gets a memory; a girl gets a classroom. That equation has always felt right to me.
Frequently asked questions
Should I volunteer the information before they ask?
Only if it comes naturally, and never as an announcement at the door. Saying "I have scented the flat for you" the moment a buyer walks in is odd, draws attention to the one thing that works best unnoticed, and makes the preparation sound like a feature rather than a standard. The better version, if you want to say something at all, is a passing line while you are already talking about the property: that you came in early to open the place up and air it out. That covers the preparation honestly, sounds like what it is, and leaves the fragrance where it belongs, which is in the background. Then if the question comes, you answer it fully. Volunteering is unnecessary. Withholding, when asked, is the thing that costs you.
What if the buyer asks what fragrance it is and wants to buy it?
Tell them, and enjoy it, because it is a good sign about the level you are running at - a buyer who is curious rather than affected has experienced the flat the way you intended. Name the register plainly: SOSA's Hotel Collection registers are the company's own hotel-inspired interpretations and SOSA is independent and not affiliated with any hotel brand, so describe the notes rather than implying a hotel connection. White tea, bergamot and cedar, or white tea, aloe and cedar, from Rs 299. If they ask where you got the machine, tell them that too. None of this damages the viewing, and a broker who is relaxed about a small question is a broker who looks relaxed about the large ones.
The flat has an actual damp problem the seller has disclosed. Can I still scent it for viewings?
Not as a response to the damp, and not in a way that makes the damp harder to notice. If a defect is known and disclosed, the buyer is entitled to encounter the property as it is and to form their own view of it, and anything that softens the evidence of a problem they are being asked to price is on the wrong side of the line, however light. The correct sequence is the one this site repeats everywhere: ventilate, clean, find and fix the source, then present. If the repair is scheduled and the disclosure is made in writing, a light background register in the rest of the property is presentation, not concealment - but you should be able to say out loud, to that buyer, exactly what you did and why, without any part of it sounding awkward. If any part of it does sound awkward, do not do it.
A buyer said it smelled nice and then asked whether the flat has been empty for a long time. What now?
That is a well-aimed question and it deserves a straight answer, because they have connected two things correctly. Tell them how long the property has been vacant, and tell them what that means practically - that a closed flat develops stale air, that you open it up and air it before every viewing, and that this one has been getting a full airing rather than a spray. If they want to know whether it has been shown before, tell them that as well. Buyers who ask sequenced questions like this are usually serious, they have done this several times, and they respond well to an agent who does not flinch. Vagueness at this exact point is what turns a serious buyer cautious, and there is nothing here worth being vague about.
Does answering honestly ruin the effect?
No, and it is worth understanding why. The value of a well-prepared property is not that the buyer is unaware it was prepared - it is that the property is pleasant to stand in and clearly cared for. Nobody thinks less of a hotel room because they know the housekeeping team made the bed. What ambient scent research supports is improved evaluations of a space and the service delivered in it, longer dwell and stronger recall, at moderate effect sizes, and none of that depends on secrecy. What would damage the viewing is the buyer discovering something you concealed, which is a completely different mechanism and works against you permanently. Answer the question, keep the level low, and let the flat do the rest.
