Reading it: praise on arrival is usually genuine. Oh, that is strong, a comment repeated by more than one person, a remark that arrives forty minutes in, or somebody quietly opening a window — those are dose signals.
The response: hold the dose. Do not add drops because somebody liked it. The level a guest praised is the level you already have.
2. The comment comes in the first sentence because that is when the reading exists. They adapt to your home within a few minutes, much as you did over a fortnight. By the time coats are off, the scent has stopped being available to them too — which is why nobody ever mentions it twice.
3. That silence is not the compliment wearing off. A great many hosts read the absence of further remarks as politeness, or as the fragrance having faded during the evening. Neither happened. The room is unchanged and their nose moved.
4. A comment is data, and not necessarily praise — so read it rather than collecting it. It smells lovely in here, said on arrival, is usually genuine and means the level is right. Oh, that is strong is a dose signal. So is the same observation from two different people in a month, or somebody opening a window without being asked.
5. And whatever the comment, do not increase the dose. This is the important one. The level that earned the compliment is the level currently running, so adding a drop as a kind of thank-you moves the room away from the only setting you have external evidence for.

The ten-minute window your guest is reading from
The whole of this page rests on one small piece of timing that almost nobody is told. A visitor is not a permanent sensor installed in your hall. They are a sensor with a battery that lasts about ten minutes, and everything they can tell you about your home is produced in the first two. That explains the shape of the remark — early, warm, unrepeated — and it also explains why so many hosts conclude that guests are being kind about something imaginary. They were not being kind. They were being prompt, and then their nose did to your flat what yours did weeks ago.
What each kind of comment actually means
Six things guests actually do and say, what each one is really reporting, and what to do about it. Every response in the fourth column is free, and three of them are to do nothing. The timing column matters more than people expect: the same sentence means one thing at the door and something quite different forty minutes into an evening.
| What they do or say | When it arrives | What it is reporting | What to do | Cost |
|---|---|---|---|---|
| It smells lovely in here ★ | First minute, at the door, unprompted | A genuine reading of the level you are currently running, taken by the only unadapted nose in the building | Nothing. Write the dose and the date on the bottle in pen and leave the setting exactly where it is | ₹0 |
| Oh, that is strong · wow · what is that? | First minute, often with a small step back | A dose above what the room needs. Intensity language is the closest a polite person gets to a complaint | Take one drop out of the next tank, not two, and wait a fortnight before reading again | ₹0 |
| The same remark from two unconnected people | Across a few weeks | Your house rather than one person's taste. Repetition across visitors is the strongest signal available to you | Act on it. One drop down if it is about strength; a source hunt if it is about character | ₹0 |
| Somebody opens a window or moves outside | Any time, and usually without comment | The clearest dose signal there is. Nobody will tell a host their flat is too much; a fair number will open a window instead | One drop down, and shorten the run. This is the row I would act on fastest | ₹0 |
| A comment forty minutes into the evening | Late, after they have settled | A level high enough to keep re-registering on a nose that should have adapted by then | One drop down, and check whether the machine restarted or a second one is running in the next room | ₹0 |
| Nothing said at all | The whole evening | Almost always nothing. Most people never comment on air, and the ones who do have a ten-minute window | Nothing. Silence is not evidence of a faded scent, and it is the most common reason a dose gets raised | ₹0 |
Holding a dose, and the free things that change what they smell
Start with what holding a dose actually involves, because it is harder than it sounds and it is the whole instruction on this page. The Hotel Collection is composed at three to six drops per tank, and the dose is per tank rather than per litre — you are scenting the mist and not the water — so a 300ml Boond at ₹899 takes exactly the same three or four drops as a 500ml Sukoon at ₹1,899. A larger machine buys hours and coverage rather than intensity, which is the single most common misunderstanding I correct by email. Three drops is the number for a bedroom, a study or a small hall; four for a sitting room; five only in a genuinely large space; six is a ceiling rather than a default. Having chosen a number, the practical difficulty is that you have no way of noticing when you drift off it, so the number has to live somewhere outside your head. Write it on the bottle with the date. Put it in the note on your phone where the wifi password lives. Anywhere, so long as the pour becomes a setting to be followed rather than a judgement to be remade every few days. And use the timers rather than leaving the machine open-ended: the Sukoon gives steady, 2H and 4H settings on a 500ml BPA-free tank rated for 270–320 sq ft, 16–18 hours per fill on low at 30–50 ml/h against 9–12 on high, with a 2.4MHz cool-mist plate, a remote, auto shut-off and three 15ml scents of your choice included. Two hours from six gives your guests a room that has arrived somewhere and settled. Fourteen unbroken hours gives them a plateau that has been climbing since breakfast.
Then the part that changes what a visitor receives far more than the fragrance does, and none of it is a product. What arrives at your guest's nose is your scent sitting on top of everything the flat has accumulated since it was last aired, and they get both at once. So air the place before people come — two openings on opposite or adjacent walls for twenty minutes, since one window is ventilation and two is exchange — and do it early enough that the room has settled again rather than five minutes before the bell. Pour a mug of water down every floor drain, basin and unused shower, particularly the guest bathroom nobody uses, because the U-bend's water seal evaporates in roughly two to four weeks of disuse and the drain then vents into the room; that sharp, faintly sulphurous note underneath a pleasant hall is the commonest thing a guest is too polite to mention. Change the bin liner and wipe the bin itself, which is usually dirtier than what goes in it, and put the washable fabric through a cycle, since cooking aerosol and body oils deposit onto cushion covers and throws and re-release for weeks after the air has moved on. Extraction on while you cook and for ten minutes afterwards, not just during. Fragrance does not remove any of that. Run a diffuser over a dry trap or a loaded sofa and your visitor receives two smells rather than one, and their first-minute reading — the only one you will ever get from them — will be of the combination.
Then the arrangement, and the constraints. If the comments cluster on one room, the honest reading is usually that one machine is doing all the work in the space with the least air in it. An entrance hall is often small, often unventilated and often where the diffuser has been put, so the level that feels correct in a sitting room lands heavily on somebody standing in a two-metre passage taking off their shoes. A Boond at ₹899 in the small room and the larger machine where people actually sit is a better arrangement than one machine turned up, and it costs less than a year of adjusting by feel. If the flat is genuinely open-plan, the Megh at ₹3,499 with a six-litre tank holds a low output for a long evening rather than a small machine worked hard. And if you would rather not manage a level at all, a reed diffuser from ₹749 holds one steady output for months with nothing to switch on — a separate alcohol-free line with its own scents, needing 24 to 72 hours to establish, so it is the right buy for a habit and the wrong one for guests arriving tonight. For tonight, a candle puts scent into a room in fifteen to twenty minutes and must be attended and put out; Bookshop candle is ₹379 for 80g. On the constraints: the water-based Hotel Collection runs in the Sukoon, Boond and Megh only, never in a reed and never in the waterless Vaayu at ₹11,999, which takes its own undiluted oil. SOSA does not make a room or linen spray for the home. Rinse the tank between scents, never substitute raw essential or carrier oils, which clog the 2.4MHz plate. And the principle: the level a guest praised is the level you already have, so the correct response to a compliment is gratitude and no other action at all.
The SOSA edit
What to do about comments, in order, which begins with three things that cost nothing and reaches a product only when the pattern of remarks says something specific. The last row is the response almost everybody has to praise, and it is the wrong one.
| Step | What it is | Why it comes here | Cost |
|---|---|---|---|
| 1. Write the current dose down ★ | Scent, number of drops, timer setting and date, in pen on the bottle | First. A compliment is evidence for a specific setting, and the setting is the thing you will otherwise forget | ₹0 |
| 2. Air the room, check the drains and the bin | Two openings for twenty minutes; a mug of water down every unused drain; a fresh liner and a wiped bin | Second, because a guest smells your fragrance and your flat's backlog in one breath and cannot separate them | ₹0 |
| 3. Take one drop out if the signals say strong | One drop, not two, then a fortnight before you read the room again | Third. The only direction worth moving on your own initiative, and it should be slow | ₹0 |
| 4. A second machine rather than a louder one | 300ml for the hall or the bedroom, running the same three to six drops per tank as the larger machine | If the comments cluster on one room. Two modest sources beat one strong one in a flat with a small entrance | ₹899 |
| 5. A timer or a reed diffuser | Steady, 2H and 4H settings with three 15ml scents included, or one unchanging level for months from ₹749 | For a level that stops climbing. A reed needs 24–72 hours to establish, so it is a habit rather than a fix for tonight | ₹1,899 / from ₹749 |
| Not the answer: an extra drop as a thank-you | The most common response to a compliment about a home's fragrance | The compliment was for the level that was running. Adding to it moves the room somewhere nobody has endorsed | — |
Versailles
I find this the most endearing problem in the whole category, and I say that as somebody who has caused it. A guest says something kind about a hall, the host beams, and within a week the dose has gone up. It is generosity, really — the thing was enjoyed, so let us have more of it — and it is the one response guaranteed to undo what earned the remark. I have watched customers do it and I have done it myself, in my own flat, with a bottle I composed, which ought to have made me immune and did not.
So the sentence I would like to leave with everybody is that a compliment is a measurement rather than a request. Somebody with a working nose walked into the level you are currently running and approved of it, which is the only external verification you are ever likely to get. Write the number down and stop touching it. And on the other side: nobody will ever tell you a room is too strong, so watch what people do instead of what they say. A window opened without comment, a suggestion of sitting on the balcony, the same observation from two people who have never met — those are the sentences your guests are actually capable of saying. Take one drop out, wait a fortnight, and go on being the person whose house smells like somewhere.
Everything is made and supported from Pune, and a part of every order funds girl-child education through Nanhi Kali. You get a home that smells like somewhere you chose; a girl gets a classroom. That equation has always felt right to me.

Facts verified August 2026: Diagnostic facts used in this guide: a closed room accumulates what it cannot exchange, so cross-ventilation needs two openings rather than one; a drain's U-bend water seal evaporates in roughly two to four weeks of disuse and then admits sewer gas, which is corrected by pouring water down the drain; microbial growth in fabric and on surfaces accelerates above about 60% relative humidity, and Indian monsoon indoor humidity commonly runs 80–95%, which is the one situation where ventilating on a wet day can import moisture rather than remove it; an air-conditioner's cold, wet evaporator coil and filter grow biofilm that is blown into the room on start-up; textiles adsorb cooking aerosol and body oils and re-release them for weeks; and olfactory adaptation makes a constant household smell undetectable to its residents within about a fortnight while visitors still perceive it. Timings: a scented candle scents a normal room in roughly 15–20 minutes, a Sukoon ultrasonic diffuser reaches a steady level in about 20 minutes from cold, and a reed diffuser needs roughly 24–72 hours.
