What each one genuinely wins: the spray wins cost and immediacy; the reed wins silence, zero attention and no electricity; the machine wins coverage, duration, remote control and cost per property across a portfolio.
The candle is excluded, and not on fragrance grounds: an unattended flame in a property you do not occupy is an insurance question before it is anything else.
The primary: the Vaayu at ₹11,999 — waterless, up to 1000 m³, 400ml for about 75 days, app and 1h/4h/8h/24h timers, key-lock, 0.9 kg.
2. Reeds in the two or three listings you show constantly, and nowhere else. From ₹749, silent, unpowered, needing no attendance and no collection, and reaching their working level in 24 to 72 hours — which is a genuine advantage for a property shown at four hours' notice and a genuine problem for one shown tomorrow.
3. No room spray, and I will give both reasons rather than one. The first is that SOSA does not make one for the home; our sprays are car perfumes. The second is that a single dose peaks and declines, so it does not survive the ninety minutes a serious viewing occupies. The first reason is why you cannot buy one here; the second is why you should not want to.
4. The candle is excluded on grounds that have nothing to do with fragrance. A candle scents a room in fifteen to twenty minutes and does it beautifully, from ₹379. It also has to be attended and put out, and an unattended flame in a property you do not occupy is an insurance question that no brokerage should want to answer.
5. Be fair about what the other two win, because a kit decision made on a rigged comparison is a bad kit decision. The spray wins cost and immediacy outright — nothing changes a small enclosed space faster or cheaper. The reed wins silence, zero attention, no electricity and no risk of anything to spill in somebody else's flat.
6. And none of it comes before the property being sound. Air the flat, fill the drain traps, deal with fabrics and cleaning. If there is a defect with a smell attached to it, that is a material fact: find it, fix it or disclose it. No item in this kit is for covering one.

The nine columns a realtor actually buys on
Most comparisons of these three formats are written for somebody scenting their own hall, which is why they compare the wrong things. You are not choosing a fragrance for a room you live in. You are choosing equipment that has to work in a building you do not own, on a schedule set by somebody else, often without you present, and it has to be recoverable afterwards. So the columns that decide it are not warmth or throw or which notes you prefer. They are time to working level, how long it holds, how much volume it covers, whether it needs a person in the room, whether it can be left in a vacant flat, whether it travels, what it costs per property, what happens if it spills on somebody else's floor, and whether you can control it without being there.
The comparison table
Six formats on the axes that decide a kit purchase rather than the ones that decide a fragrance purchase. Read it as a professional reading a spec sheet: nothing here is described as best overall, and the two columns the spray wins are printed in the same size as the six the machine wins. Prices are current and the coverage figures are the manufacturer's ratings rather than estimates.
| Format | Time to working level | How long it holds | Left alone in a vacant flat | Cost to run per property | Where it belongs in the kit |
|---|---|---|---|---|---|
| SOSA Vaayu ₹11,999 ★ | Minutes to a working level, well inside two hours to a settled viewing level | As long as the timer runs — 1h, 4h, 8h or 24h — at a level you set | Yes. Auto-stop and a key-lock, and nothing liquid to spill on stone | A fixed cost, not a per-listing one. 400ml runs about 75 days and the unit moves between properties | The primary tool. Up to 1000 m³, under 38 dB, 0.9 kg, four hotel-inspired scents supplied |
| Reed diffuser from ₹749 | 24 to 72 hours | Months, at a small constant level that cannot be raised | Yes, indefinitely — no power, no attention, nothing to collect | ₹749 to ₹849 per listing, plus ₹2,399 for a 300ml refill | The two or three listings shown constantly at short notice, and every bathroom and hall |
| Room spray (not made by SOSA for the home) | Immediate — the fastest thing in the comparison | Peaks within a minute and declines with nothing replacing it | No — it requires you to be there at the right moment | A few hundred rupees, repeatedly, per viewing | Wins cost and immediacy. A small enclosed space you are standing in. Not a ninety-minute appointment |
| Scented candle from ₹379 | 15 to 20 minutes | Only while it burns, and only with somebody in the room | No, and this is the firm one — an unattended flame in a property you do not occupy is an insurance question | ₹379 to ₹799 per candle, and your presence throughout | Occupied properties only, with the owner present. Excluded from a viewing kit on safety grounds |
| SOSA Sukoon ₹1,899 | About twenty minutes from cold | 16 to 18 hours a fill on low, with steady/2H/4H timers | Not advisable — water-based, adding 30 to 50 ml of water an hour, and half a litre of it above a client's floor | ₹1,899 plus ₹299 for 15ml of fragrance; three scents included | One occupied, air-conditioned room — a study or an office. 270–320 sq ft |
| SOSA Aangan ₹25,999 | Minutes, and it is usually left on a schedule | Programmable schedules, run continuously in commercial use | Yes, and it is normally installed rather than carried | A fixed installation cost for one venue rather than a portfolio | Sales galleries, clubhouses and ducted very large villas past 1000 m³. Under 42 dB |

The kit, and how it is actually used in a week
Start with what lives in the car, because that is the practical form the answer takes. One Vaayu, a spare bottle of its oil, and a short extension lead, which sounds trivial until you are standing in an empty flat whose only accessible socket is behind a bed. The machine is 165 × 80.5 × 215 mm and 0.9 kg, so it lives in a boot or a door pocket rather than requiring a trip. Set it down at waist height or above in the entrance zone, away from the direct path of an air-conditioning vent, plug it in, choose low, set the 4h timer for a single appointment or the 8h for a day of them, and engage the key-lock before you leave the room. The 400ml tank runs roughly 75 days at these settings, which for most agents is one refill a quarter rather than a purchase per property, and it arrives with four hotel-inspired scents so the first several months cost nothing further. The register to run is the quiet one — the Ritz-Carlton-inspired Quiet Luxury direction of white tea, bergamot and cedar, or the 1 Hotels-inspired Forest Suite where a property runs warm — because a viewing scent is chosen to be impossible to dislike rather than to be admired.
Then the listings that keep something permanently, which is a smaller number than most agents assume. A reed earns its place in a property that is furnished, occupied or regularly visited, that gets shown at a few hours' notice, and that you are not always able to reach in advance. Two or three per portfolio is usually the honest count. Put them in the entrance hall and the guest bathroom rather than in the drawing room, give them their 24 to 72 hours before they matter, and buy the 130ml from ₹1,249 for a listing you expect to hold for a season. What a reed will not do is rescue a large empty flat, and buying six of them to try is how agents end up believing the format is poor. On the candle, I will be blunter than the category usually is: a candle is a beautiful object and a genuinely fast one, fifteen to twenty minutes from ₹379, and it is out of this kit entirely. Not because it smells wrong — because it must be attended and put out, and a flame left burning in a property you do not occupy is a liability question that no commission is worth. If the owner is living there and is present, that is their decision to make in their own home. It is not a tool for a viewing you are running.
Then the economics and the line the kit does not cross. The Vaayu's ₹11,999 is a fixed cost, and that is the whole commercial argument rather than the coverage figure. Because it weighs 0.9 kg and sets up in two minutes, the same unit serves every property you show, so the cost per listing falls every month you own it, while consumables bought per property never fall at all. I am not going to attach a return to that, because there is no defensible figure for what scent does to a property's price, its offer level or its time on market, and anybody quoting you one has made it up. What is honestly claimable is narrower and still worth the money: it changes how a property feels on arrival and how memorable a visit is, which puts it in the same category as photography, styling and lighting. Presentation, not persuasion. And the line: none of this kit is for covering a defect. If a listing has damp, a leak, a dry trap, smoke damage or anything with a structural cause, that is a material fact about the property — find it, fix it or disclose it, and scent only a property that is genuinely sound. On the constraints: the Vaayu takes its own undiluted oil rather than the water-based Hotel Collection bottles, which belong in the ultrasonic Sukoon, Boond and Megh; and those three add 30 to 50 ml of water an hour, which rules them out of a closed vacant flat in monsoon.
The SOSA edit
The kit in buying order, with the honest role of each item beside it. The candle appears in the list because leaving it out silently would be its own kind of dishonesty, and the last row is the product we do not make, so that you can see exactly where the comparison above is coming from.
| Buy | What it is | Its job in the kit | Price |
|---|---|---|---|
| 1. SOSA Vaayu ★ | Waterless cold-air nebulisation, up to 1000 m³, 400ml for about 75 days, app and 1h/4h/8h/24h timers, under 38 dB, auto-stop, key-lock, 0.9 kg | The primary tool, carried between listings. A fixed cost rather than a per-property one | ₹11,999 |
| 2. Reed diffusers | Alcohol-free, unpowered, silent, 24 to 72 hours to establish, months per bottle | The two or three listings shown constantly at short notice, plus bathrooms and halls | from ₹749 |
| 3. The viewing register | Quiet, cool and hard to dislike — white tea, bergamot and cedar, or cedarwood, vetiver and green leaves for a warm property | Chosen for anonymity rather than impact. Four hotel-inspired scents ship with the Vaayu | included / ₹299 |
| 4. SOSA Aangan | Up to 3,000 m³, 800ml, HVAC-connected or standalone, programmable schedules, under 42 dB | A sales gallery, a clubhouse or a ducted very large villa. Not a second machine for an apartment | ₹25,999 |
| 5. Scented candles | 15 to 20 minutes to scent a room, and beautiful while they burn | Occupied properties with the owner present only. Out of a viewing kit — an unattended flame in a flat you do not occupy is an insurance question | from ₹379 |
| Not made by SOSA: a room spray for the home | Our sprays are car perfumes for a two-cubic-metre cabin, where a single dose is the correct format | Stated so the comparison can be weighed. A spray wins cost and immediacy and cannot win duration | — |
Versailles
I like this question because it is asked the way a professional asks about tools rather than the way a shopper asks about smells, and it deserves an answer in the same register. So the first thing I would say is that two of the three formats in the title win columns that the one I sell does not, and any comparison that fails to say so is marketing wearing a lab coat. A spray changes the air in three seconds for a couple of hundred rupees and nothing else in this trade comes close. A reed sits in a client's hall for five months, silent, unpowered, needing nothing from you, and no machine will ever do that.
What decides it is that a scheduled viewing in a large property is a duration problem in a volume problem, and those are the two columns a machine exists to win. Coverage you can state, duration you can time, intensity you can set, a lock so nobody else can change it, and 0.9 kg so it belongs to your practice rather than to any one listing. Keep your reeds in the properties that are shown at no notice, carry the machine to everything else, and leave the candle at home in somebody else's occupied living room where it is safe and lovely. I would rather lose a sale to a reed diffuser than have an agent light something in an empty flat because I was vague about it.
Everything is made and supported from Pune, and a part of every order funds girl-child education through Nanhi Kali. You get a space that smells like somewhere considered; a girl gets a classroom. That equation has always felt right to me.
