★ SOSA · when active diffusion is the honest answer
Concentration peaks at the reeds, so a passive diffuser cannot put fragrance where the bottle is not — try the ceiling fan first, because it is free and it supplies the one thing a reed structurally lacks

Founder Diaries · Scent Distribution · Reaching the Bed
The first thing worth buying: Sukoon at ₹1,899 — 500ml tank, 270–320 sq ft, 16–18 hours on low, three 15ml Hotel Collection scents included. It moves air. It also dilutes the oil in water, adds humidity, needs filling, and in hard-water cities can leave white mineral dust.
The waterless option: Safar at ₹3,999 shatters undiluted oil into a dry mist — no water, no dilution, no added humidity. It is named and sold as a car and travel diffuser, SOSA has published no room coverage figure for it, and its timer runs one, two or three hours before it needs recharging.
The honest gap: between Safar and the ₹11,999 Vaayu there is no mid-sized waterless bedroom machine, and Vaayu — rated to 1000 m³, roughly 2,000–3,000 sq ft — is the wrong purchase for one bedroom. Also: switching mechanism may mean switching scent. Reed oil cannot go into an ultrasonic machine.
Evening Calm₹799This is the best free advice in the whole of this subject, and it belongs at the top of the list rather than buried under the products. A reed diffuser lacks transport; a fan is transport. Run it low, in a closed room, with the bottle a metre or two out of the direct downdraught rather than underneath the blades, and the fragrance stops being an object on a table and starts being something in the air of the room. Give it a full day before you judge, and use all six reeds while you are testing. Two things are true at once and you should hear both: it will improve the reach and it will shorten the life of the bottle. A running AC in a closed room does something similar — it recirculates and distributes well, which is why a bedroom often smells strongest at night, while drying the air and speeding evaporation. Just never put the bottle in the direct blast, which strips the reeds and throws everything at one wall.
Sukoon₹1,899An ultrasonic diffuser vibrates a water-and-oil mixture into a visible cool mist and sends it into the room. It is a genuine step up in reach because it moves air, and Sukoon is rated at 270–320 sq ft with a 500ml tank and 16–18 hours on low, with three 15ml Hotel Collection scents included so you are not buying oil separately on day one. For one bedroom this is usually the right answer and it must never be skipped on the way to something dearer. The honest costs: the oil is diluted in water rather than delivered undiluted, the output adds humidity to the room, the tank has to be filled, and in a hard-water city it can leave a fine white mineral dust on surfaces. It needs a socket, and it makes some sound.
Mountain Breeze₹849Safar uses pressurised air to shatter undiluted oil into a dry micro-mist that travels with the room’s own airflow — no water, no dilution, no added humidity, no white dust. It holds 20ml, runs on a 2000 mAh battery over Type-C, is fully cordless at 6.9 cm, and has three speeds and a one, two or three-hour auto-off timer. Now the disclosures, which I will make every time: it is named and sold as a car and travel diffuser, and SOSA’s own page describes it for a car, a handbag, a desk, a bedside and a hotel room. SOSA has published no room coverage figure for it and I will not invent one. The timer means it is not set-and-forget, and the battery needs recharging. Thick, sticky or water-based blends can clog it.

You have asked for something a reed diffuser cannot do, and you have asked for it precisely. A passive diffuser puts its highest concentration at the reeds, so the only reliable way to be in the strong part of it is to be next to it. Take the bottle off the bedside table and you have moved the strong part away from your head; that is not a fault in the product and it is not a fault in your reasoning. What you are asking for is delivery rather than collection — fragrance brought to where you are, rather than fragrance waiting where it is — and delivery requires moving air. Here is the order I would work through, starting with the version that costs nothing.
Quick answers — read this first
Free first, and it genuinely works: a ceiling fan on low in a closed room, with the reed diffuser somewhere sensible but out of the direct downdraught. A fan is the transport a reed structurally lacks, and it is the best free advice in this whole subject. It shortens the bottle’s life, because air moving past the reeds evaporates oil faster.The first thing worth buying: Sukoon at ₹1,899 — 500ml tank, 270–320 sq ft, 16–18 hours on low, three 15ml Hotel Collection scents included. It moves air. It also dilutes the oil in water, adds humidity, needs filling, and in hard-water cities can leave white mineral dust.
The waterless option: Safar at ₹3,999 shatters undiluted oil into a dry mist — no water, no dilution, no added humidity. It is named and sold as a car and travel diffuser, SOSA has published no room coverage figure for it, and its timer runs one, two or three hours before it needs recharging.
The honest gap: between Safar and the ₹11,999 Vaayu there is no mid-sized waterless bedroom machine, and Vaayu — rated to 1000 m³, roughly 2,000–3,000 sq ft — is the wrong purchase for one bedroom. Also: switching mechanism may mean switching scent. Reed oil cannot go into an ultrasonic machine.
The short answer
Short answer: use an active diffuser, and try a ceiling fan before you buy one. A reed diffuser is a passive capillary device — oil climbs six fibre reeds and evaporates, with nothing to push the vapour anywhere — so its concentration peaks at the bottle and falls with distance. That is the design rather than a defect. Requiring the fragrance to be strong at a point several metres from the bottle is asking a passive source for something it structurally cannot provide, at any price and with any oil.
What an active diffuser changes: it moves air. An ultrasonic vibrates a water-and-oil mixture into a visible cool mist; a waterless cold-air nebuliser shatters undiluted oil into a dry micro-mist that travels with the room’s own airflow. In both cases fragrance is introduced into moving air rather than released from an object on a table, which is why it can be present where the machine is not.
Shop: Sukoon ₹1,899 for one bedroom, and it should never be skipped on the way to something dearer. Safar ₹3,999 if you want undiluted oil and no added humidity, with the car-and-travel caveat above. Keep the reed as well if you like it — it is silent, needs no power and works in a power cut, and it costs roughly ₹13–₹15 a day. Free shipping above ₹499.

Straight answer
What should I use if I want fragrance at my bed but not the bottle beside it?
1. Accept the limit, because it is a design and not a defect. Concentration from a reed diffuser is highest at the reeds. Remove the bottle from your bedside and you have removed the peak from your bedside. No reed count, no bottle size, no stronger oil and no second bottle changes that, because all of those raise emission — how much leaves the bottle — and none of them adds transport, which is how far it travels.
2. Try the ceiling fan before you buy anything. On low, in a closed room, with the diffuser somewhere out of the direct downdraught. A fan is exactly the transport a reed does not have, and for a fair number of people it is the whole answer. The trade is that the bottle will not last as long, because moving air evaporates oil faster. I say that plainly so it is your choice rather than a surprise.
3. If that is not enough, buy the mechanism at ₹1,899 and not more. Sukoon is an ultrasonic machine: 500ml tank, 270–320 sq ft, 16–18 hours on low, three 15ml Hotel Collection scents in the box. It genuinely moves air, which is the entire difference. In exchange the oil is diluted in water, the room gains humidity, the tank needs filling, and in a hard-water city you may see a fine white dust.
4. If water is the objection, Safar at ₹3,999 — with its caveats stated. It shatters undiluted oil into a dry mist, so no dilution, no humidity and no mineral dust, and it is cordless with three speeds. It is named and sold as a car and travel diffuser; SOSA has published no room coverage figure for it, so I will not quote one; and its timer runs one, two or three hours, after which it stops and eventually needs recharging. It is a device you switch on deliberately, not one you forget about.
5. Do not buy Vaayu for one bedroom. At ₹11,999 it is rated to 1000 m³, roughly 2,000–3,000 sq ft. In a bedroom of 120 sq ft nine-tenths of it is wasted. And between Safar and Vaayu, SOSA has no mid-sized waterless bedroom machine — that is a real gap in our range and I would rather name it than sell around it.

TL;DR: a passive diffuser cannot put fragrance where the bottle is not — that is its design. Ceiling fan on low first, free. Then Sukoon ₹1,899, which moves air. Then Safar ₹3,999, waterless but named and sold as a car and travel diffuser with a 1, 2 or 3-hour timer. Not Vaayu for one bedroom.
The first honest step into active diffusion
Sukoon ultrasonic diffuser ₹1,899
A 500ml tank, 270–320 sq ft, 16–18 hours on low, and three 15ml Hotel Collection scents included. A piezo plate vibrates a water-and-oil mixture into a visible cool mist and pushes it out into the room, which is why it can be present where the machine is not. The costs are real: the oil is diluted in water, the room gains humidity, the tank needs filling, hard water can leave white mineral dust, and it needs a socket. For one bedroom it is very often the correct purchase and I would not let you walk past it.
Why a passive source cannot meet this requirement, stated without apology
Six fibre reeds standing in a bottle of oil form a very particular kind of device. Oil climbs them by capillary action and evaporates from their surface at whatever rate the room’s temperature, humidity and airflow allow. There is no pump, no plate, no fan, no heat and no energy input of any kind. Once a molecule has left the reed it goes wherever the room’s air takes it, and there are only two ways it can travel: molecular diffusion, which is real and far too slow to cross metres of a bedroom in any useful time, and whatever air the room happens to be moving. That second process does nearly all the work, and it belongs to the room rather than to the bottle.
Which means the shape of what a reed produces is fixed: a peak at the source, falling away in every direction. You can move that peak, raise it, and make it last longer. You cannot separate it from the bottle. So the sentence I want to smell it at my bed but I do not want the bottle at my bed is, in physical terms, a request to have the maximum somewhere other than where the maximum is. It is a perfectly sensible thing to want. It is simply not a thing a passive device delivers, and any brand telling you otherwise is describing a room it has never seen. There is no published figure for how far a reed diffuser projects, we do not have one, and I will not invent one in feet or metres to make this page tidier.
The clearest way I know to explain the alternative is a question people ask when they get home from somewhere lovely: why can I never find the diffuser in a good hotel room? Usually because there is not one in the room to find. The scent has been introduced into the building’s moving air rather than released from an object on a table, so there is no gradient to walk up and no source to locate — it is simply present in the air you are in. That is the experience you are describing when you say you want to smell it from the bed without the bottle beside you. It is achievable. It just belongs to a different mechanism.
The three options, cheapest first
In strict order of cost, because the free one is not a formality. A meaningful share of people who write to me with this exact requirement solve it with something they already own and never need to spend anything.

OPTION ONE · FREE
The ceiling fan you already have, on low
Evening Calm₹799This is the best free advice in the whole of this subject, and it belongs at the top of the list rather than buried under the products. A reed diffuser lacks transport; a fan is transport. Run it low, in a closed room, with the bottle a metre or two out of the direct downdraught rather than underneath the blades, and the fragrance stops being an object on a table and starts being something in the air of the room. Give it a full day before you judge, and use all six reeds while you are testing. Two things are true at once and you should hear both: it will improve the reach and it will shorten the life of the bottle. A running AC in a closed room does something similar — it recirculates and distributes well, which is why a bedroom often smells strongest at night, while drying the air and speeding evaporation. Just never put the bottle in the direct blast, which strips the reeds and throws everything at one wall.
Cost: nothing, unless you count weeks off the bottle. Which is a genuine cost, and it is yours to weigh.

OPTION TWO · ₹1,899
Sukoon — ultrasonic, and where I would have most people stop
Sukoon₹1,899An ultrasonic diffuser vibrates a water-and-oil mixture into a visible cool mist and sends it into the room. It is a genuine step up in reach because it moves air, and Sukoon is rated at 270–320 sq ft with a 500ml tank and 16–18 hours on low, with three 15ml Hotel Collection scents included so you are not buying oil separately on day one. For one bedroom this is usually the right answer and it must never be skipped on the way to something dearer. The honest costs: the oil is diluted in water rather than delivered undiluted, the output adds humidity to the room, the tank has to be filled, and in a hard-water city it can leave a fine white mineral dust on surfaces. It needs a socket, and it makes some sound.
Do not be tempted by tank size: Megh at ₹3,499 holds six litres and runs about a hundred hours, and covers roughly 215 sq ft — less than this. Capacity is runtime, not room.

OPTION THREE · ₹3,999
Safar — waterless, undiluted, and honestly labelled
Mountain Breeze₹849Safar uses pressurised air to shatter undiluted oil into a dry micro-mist that travels with the room’s own airflow — no water, no dilution, no added humidity, no white dust. It holds 20ml, runs on a 2000 mAh battery over Type-C, is fully cordless at 6.9 cm, and has three speeds and a one, two or three-hour auto-off timer. Now the disclosures, which I will make every time: it is named and sold as a car and travel diffuser, and SOSA’s own page describes it for a car, a handbag, a desk, a bedside and a hotel room. SOSA has published no room coverage figure for it and I will not invent one. The timer means it is not set-and-forget, and the battery needs recharging. Thick, sticky or water-based blends can clog it.
Buy one, not several, and buy it for the mechanism at personal scale rather than in the expectation that it will fill a living room.
The comparison, with every trade-off on the table
What each option actually delivers against this specific requirement — fragrance at the bed, bottle not at the bed — and what it costs you in exchange. The last row is the purchase I would talk you out of and the gap in our own range.
Delivery, not collection
Four ways to get fragrance to a bed, and what each one costs
| Option | Mechanism | What it gives you at the bed | What it costs you |
|---|---|---|---|
| Ceiling fan + the reed you own ★ | Passive source, borrowed transport | The biggest free improvement there is | Free; shortens the bottle’s life |
| Reed alone, moved further away | Passive capillary, no transport | Very little — the peak leaves with the bottle | ₹749–₹849; this is the arrangement that does not meet the requirement |
| Sukoon ultrasonic ★ | Water-and-oil mist, moves air | 270–320 sq ft; presence rather than a corner | ₹1,899; diluted oil, added humidity, filling, possible white dust, a socket |
| Safar waterless | Undiluted oil as a dry micro-mist | The mechanism at personal scale. No coverage figure is published and none is quoted here | ₹3,999; named and sold as a car and travel diffuser; 1/2/3-hour timer; needs recharging |
| Megh 6-litre ultrasonic | Water-and-oil mist, large tank | About 215 sq ft — less than the ₹1,899 Sukoon | ₹3,499 for runtime and humidity, not for reach |
| What I would talk you out of: Vaayu in one bedroom | Waterless cold-air nebulising | 1000 m³, roughly 2,000–3,000 sq ft. Nine-tenths wasted in a bedroom | ₹11,999. It earns its price on a whole floor, not one room |
| The gap: nothing sits between Safar and Vaayu | — | SOSA has no mid-sized waterless bedroom nebuliser. Nothing is “a Vaayu for one room” | Named rather than sold around |

The SOSA principle
A reed diffuser asks you to come to it. An active diffuser brings it to you.
Which is the whole difference between collection and delivery — and the reason this particular requirement is a mechanism question rather than a fragrance one.
Switching mechanism may mean switching scent — read this before you order
This is the single most likely disappointment when someone moves from a reed to a machine, and it has nothing to do with reach. The oils are not interchangeable. Reed oil is formulated for capillary wicking on a heat-stable CCT carrier and cannot go into an ultrasonic machine. The water-based Hotel Collection oils are made for ultrasonic diffusion and cannot go into reeds — there is no hotel-inspired reed diffuser, in either direction. Safar takes pure fragrance oil and can be clogged by anything thick, sticky or water-based. So if you have fallen in love with Evening Calm in a reed and you buy a machine expecting to pour it in, the answer is no, and I would much rather you knew that now.
The way I would actually handle it is to treat the machine as an addition rather than a replacement. Keep the reed — it is doing something the machine does not, which is sitting silently on a table for six to eight weeks with nothing to fill, nothing to charge, nothing to switch on and nothing to remember, working right through a power cut, at roughly ₹13 to ₹15 a day, and never breaking because there is nothing in it to break. Then run the machine when you want the room delivered to rather than collected from. One more thing worth saying because people buy it by mistake: the ₹299 Hotel Collection 15ml is a refill for an ultrasonic machine. It is not a cheap way into SOSA and it is useless without hardware. The cheapest genuine entry is a 50ml reed at ₹749.
Asking a reed diffuser to be strong where it is not, is asking a candle to light the next room. Nothing is wrong with the candle.

What to buy, and what not to

The honest ladder
From free to ₹3,999, and where to stop
| Buy | What it is | When it is the right answer | Price |
|---|---|---|---|
| 1. Ceiling fan on low, door closed ★ | Borrowed transport for the reed you already own | Always first. It costs nothing and it is the best free fix there is | Free |
| 2. Sukoon ultrasonic | 500ml, 270–320 sq ft, 16–18h on low, three 15ml Hotel Collection scents included | When you want the room delivered to and one bedroom is the whole job. Never skip it for something dearer | ₹1,899 |
| 3. Safar waterless | Undiluted oil as a dry mist, 20ml, cordless, three speeds, 1/2/3-hour timer. Named and sold as a car and travel diffuser; no published room coverage figure; needs recharging | When water, dilution, humidity or mineral dust are the objection, and you will switch it on deliberately. Buy one, not several | ₹3,999 |
| 4. Keep the reed as well | Silent, no power, nothing to fill or charge, works in a power cut, never breaks, roughly ₹13–₹15 a day | Alongside a machine, not instead of it. The two do different jobs | ₹749–₹849 |
| 5. The right oil for the machine | Water-based Hotel Collection is ultrasonic-only; reed oil cannot go in a machine; Safar takes pure fragrance oil. The ₹299 15ml is a refill, never a first purchase | Before you assume your favourite reed scent transfers. It does not | 15ml ₹299 · 100ml ₹999 |
| The honest gap: no mid-sized waterless bedroom machine | Nothing sits between Safar ₹3,999 and Vaayu ₹11,999, and Vaayu at 1000 m³ — roughly 2,000–3,000 sq ft — is the wrong purchase for one bedroom | Named rather than sold around | ₹1,899 / ₹3,999 |
Honest notes for buyers: SOSA reed diffusers come in 50ml and 130ml only, alcohol-free on a heat-stable CCT base, phthalate-free, paraben-free, IFRA-compliant and 0 ppm formaldehyde, with six fibre reeds in a refillable glass bottle, composed in Pune. There is no published figure for how far a reed diffuser projects and none is invented here; reach depends on room volume, containment and air movement. No coverage figure exists for Safar and none is quoted. SOSA publishes no oil-consumption rate for its machines, so no machine running cost is computed on this page. Fragrance does not remove an unwanted smell — deal with the source, then ventilate, then add fragrance. Free shipping above ₹499.

The oil that goes in the machine
Hotel Collection · ultrasonic only ₹299 / 15ml
Water-based fragrances made for ultrasonic machines, and SOSA’s own interpretations inspired by the world’s finest hotels — SOSA is independent and not affiliated with any hotel brand. Three 15ml bottles come with Sukoon, so you are not buying oil on day one. What they cannot do is go into reeds, and reed oil cannot come the other way. The 15ml at ₹299 is a refill rather than a way in; without a machine it does nothing. 100ml ₹999, 300ml ₹1,799.

A note from Sonal
Of all the letters in this subject, this is the one I find easiest to answer honestly, because the person writing has already worked out the mechanism without knowing the vocabulary for it. I want to smell it from my bed without the bottle beside me is a precise description of the difference between a passive source and an active one. You are not asking for a better fragrance. You are asking for delivery, and a reed diffuser only offers collection.
So I will not pretend otherwise, and I will not sell you a bigger bottle. What I will do is put the free option first and mean it. If there is a ceiling fan in that bedroom, run it low with the door closed for a night or two and see what happens, because a fan is precisely the missing component and it is already installed. Some of you will stop there. If you do not, go to Sukoon at ₹1,899 and stop there for one bedroom. Please do not let anybody sell you a ₹11,999 machine rated for two to three thousand square feet to scent a room of a hundred and twenty.
And keep the reed. I would say that even if it cost us the machine sale. It is silent, it takes no socket, it needs nothing filled or charged, it carries on in a power cut, it costs about thirteen or fifteen rupees a day, and it is an object rather than an appliance — which matters in a room you are trying to keep calm. It simply cannot put fragrance where it is not. That is the one thing it was never built to do, and now you know exactly what to buy for it. Everything is composed in Pune, and a part of every order funds a girl’s classroom through Nanhi Kali.
Frequently asked questions
What should I use to smell fragrance from my bed without the bottle beside me?
An active diffuser, after you have tried a ceiling fan on low in a closed room. A reed diffuser is a point source with no transport: its concentration peaks at the reeds, so moving the bottle away moves the strong part away. An ultrasonic like Sukoon at ₹1,899 moves air and covers 270–320 sq ft; Safar at ₹3,999 diffuses undiluted oil without water, though it is named and sold as a car and travel diffuser and its timer runs one, two or three hours.
Would a bigger reed diffuser reach my bed from across the room?
No. Bottle volume is a duration specification, not a coverage one — a 130ml runs 14–18 weeks against 6–8 for a 50ml and reaches exactly as far. The clearest proof is on our own shelf: Megh at ₹3,499 has a six-litre tank and roughly a hundred hours of runtime and covers only about 215 sq ft, less than the ₹1,899 Sukoon’s 270–320. Capacity buys runtime; it does not buy room.
Can I put my reed diffuser oil into an ultrasonic machine?
No, and not the other way either. Reed oil is formulated for capillary wicking and cannot go into an ultrasonic; the water-based Hotel Collection is made for ultrasonic machines and cannot go into reeds; Safar takes pure fragrance oil and can be clogged by thick, sticky or water-based blends. Switching mechanism may mean switching scent, so plan for the machine to run a different fragrance from the reed you love.
Should I buy Vaayu so I never have to think about it again?
Not for one bedroom. Vaayu at ₹11,999 is rated to 1000 m³, roughly 2,000–3,000 sq ft, and in a room of 120 sq ft nine-tenths of that capability is wasted. It earns its price on a whole floor, an open-plan living-dining space, a large home or a commercial room. And it is worth knowing that between Safar at ₹3,999 and Vaayu, SOSA has no mid-sized waterless bedroom machine — that is a real gap in the range rather than something I would paper over.
Why can I never find the diffuser in a good hotel room?
Usually because there is not one in the room. The scent is introduced into the building’s moving air rather than released from an object on a table, so there is no gradient to walk up and no source to locate — it is simply in the air you are breathing. That is exactly the experience you are describing when you say you want fragrance at your bed without a bottle on the table, and it is why the answer is an active diffuser rather than a different reed.
Scent distribution · delivery rather than collection
Try the fan first. Then Sukoon at ₹1,899 — and stop there for one bedroom
Sukoon covers 270–320 sq ft with a 500ml tank, 16–18 hours on low and three 15ml Hotel Collection scents included. Safar at ₹3,999 diffuses undiluted oil without water, and is named and sold as a car and travel diffuser with a 1, 2 or 3-hour timer and a battery to recharge. Keep the reed too — silent, no power, works in a power cut, roughly ₹13–₹15 a day. Free shipping above ₹499, and a portion of every order supports girl-child education through Nanhi Kali.

More on getting fragrance to the bed
- My diffuser is across the bedroom and I can’t smell it from my bed — the four changes, in order.
- How to make the fragrance reach the bed — why distance is the dominant lever.
- Should it go on the bedside table? — yes, and it is not a compromise.
- Only 100 sq ft and still nothing from the bed — small does not mean even.
- A 10 × 12 bedroom with the diffuser near the door — the worst spot in the room.
- Move it closer, or buy better projection? — move it, and why free comes first.
- Fragrance wherever I am — are reeds enough? — for evenness, honestly no.
- Strong walking in, gone once in bed — two mechanisms stacking.
- Two diffusers on opposite sides? — two hills, not a plateau.

Editorial standards & sources
About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body, on what to use when fragrance is wanted at a bed without a diffuser bottle beside it. The reasoning distinguishes passive capillary diffusion, in which concentration peaks at the source, from active diffusion, in which fragrance is introduced into moving air. No projection distance is quoted for any reed diffuser and no room coverage figure is quoted for Safar, because none is published. Longevity and cost-per-day figures assume ordinary Indian household use and vary with room size, ventilation, temperature and reed count. Review quotations are from verified SOSA buyers.SOSA facts verified August 2026: Reed diffusers in 50ml and 130ml only — Morning Freshness ₹749 / ₹1,249, Evening Calm ₹799 / ₹1,299, Garden Bloom ₹799 / ₹1,299, Mountain Breeze ₹849 / ₹1,349, Fresh Brew ₹849 / ₹1,349. 50ml suits rooms up to about 150 sq ft and runs 6–8 weeks; 130ml suits above 150 sq ft and runs 14–18 weeks; roughly ₹13–₹15 a day. Six fibre reeds, not rattan, in a refillable glass bottle, on a heat-stable CCT carrier rather than DPG, alcohol-free, phthalate-free, paraben-free, IFRA-compliant, 0 ppm formaldehyde, tested at 45°C and 85% RH, composed in Pune. Machines: Boond ₹899 (300ml, up to about 150 sq ft, about 6 hours, USB), Sukoon ₹1,899 (500ml, 270–320 sq ft, 16–18h on low, three 15ml Hotel Collection scents included), Megh ₹3,499 (6 litres, about 100 hours runtime, only about 215 sq ft), Safar ₹3,999 (waterless cold diffusion of undiluted oil, 20ml, 2000 mAh Type-C battery, up to 10 hours continuous or about 30 hours intermittent per charge, three speeds, 1/2/3-hour auto-off timer, 6.9 cm — named and sold as a car and travel diffuser, with no published room coverage figure), Vaayu ₹11,999 (up to 1000 m³, roughly 2,000–3,000 sq ft, 400ml tank, under 38 dB). Between Safar and Vaayu SOSA has no mid-sized waterless bedroom machine, and this guide names that gap rather than stretching a product to cover it. Hotel Collection oils are water-based and ultrasonic-only: 15ml ₹299, 100ml ₹999, 300ml ₹1,799; the 15ml is a machine refill and never a first purchase. Reed oil and the Hotel Collection are not interchangeable in either direction, and there is no hotel-inspired reed diffuser. No health, air-quality or sleep claims are made for any SOSA product, and fragrance does not remove an unwanted smell — deal with the source, then ventilate, then fragrance. Free shipping above ₹499.
