Founder Diaries · Reed Diffusers & Room Scenting
Do more reeds waste the oil? They spend it faster, which becomes waste when the extra intensity is not buying you anything you wanted. Reed count controls the rate at which oil evaporates, so roughly doubling the sticks roughly doubles the consumption, and a SOSA reed diffuser that lasts about 6 to 10 weeks moves toward the short end of that window rather than the long one. Now do the arithmetic that matters. If loading the reeds means you buy two Rs 749 bottles where one would have done, that is Rs 1,498 - and a Boond ultrasonic at Rs 899 with a water-based Hotel Collection bottle at Rs 299 is Rs 1,198, which is less money for an active machine that does the room job the extra reeds were never going to do.
Can a reed diffuser be too strong in a bedroom at night? It can, and it is worth taking seriously rather than pushing through. A bedroom is a small volume of air that you breathe for seven or eight hours with the door shut, so a level that feels lovely for ten minutes in the evening can be a great deal at three in the morning, and for a sensitive person it is enough to disturb sleep. Households include children, elderly relatives, pregnant family members and pets, all of whom are in that air far longer than any visitor, so gentle is always the correct default. If anyone reports a headache or a heavy head, treat that as a recalibration signal rather than something to get used to: take reeds out, or move the bottle out of the bedroom entirely. We make no health claims either way - this is simply how to dose a room sensibly.
See the Safar
Facts verified August 2026: A reed diffuser is a passive system - oil travels up the reeds by capillary action and evaporates at the rate the room's temperature and air movement allow, so concentration is highest at the bottle and falls away with distance. A SOSA reed diffuser lasts about 6 to 10 weeks. Reed prices: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml sizes from ₹1,249. An active diffuser adds energy to move fragrance into the air. SOSA's ultrasonic machines are Boond (₹899), Sukoon (₹1,899) and Megh 6L (₹3,499); they run the water-based SOSA Hotel Collection, 15ml ₹299, 100ml refill ₹999, Pack of 7 at 15ml ₹1,799. An ultrasonic mixes fragrance with water, which adds humidity to the room, can dilute the scent, and in hard-water areas can leave white dust. The SOSA Safar (₹3,999) is a waterless, cordless, rechargeable cold-diffusion perfume diffuser with a 2000 mAh battery, diffusing pure undiluted oil with no water and no white dust; SOSA's own copy lists it as best for car, handbag, work desk, bedside, hotel and travel, work-from-home and gifting. It ships with three hotel-inspired waterless blends, chosen as one of three bundles: Ritz-Carlton Inspired, Westin Inspired and 1 Hotels Inspired; St. Regis Inspired, Shangri-La Inspired and Four Seasons Inspired; or W Hotels Inspired, Ritz-Carlton Inspired and Westin Inspired. No square-foot or cubic-metre coverage figure is published for the Safar, so none is stated here or anywhere else by us; it is a personal-space diffuser, not a whole-room machine. The SOSA Vaayu (₹11,999) is a waterless cold-air system covering approximately 1000m³ of connected volume, with a Bluetooth app and timer, and it ships with four hotel-inspired waterless blends included in the box. Format distinction: the Safar and the Vaayu run waterless oil and each arrive with their own blends, while the ₹299 Hotel Collection bottle is water-based and goes into the ultrasonic machines only. The two formats are not interchangeable. Scent perception is personal and varies between people in the same room, and coverage figures assume connected air volume rather than closed doors. Ventilation and cleaning come first; fragrance is an addition to a well-kept room and never a substitute for either, and we make no health, therapeutic or air-purification claims. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any hotel brand. Made in India, cruelty-free and vegan. A portion of every order supports girl-child education through Nanhi Kali. Questions about a specific room are answered on WhatsApp: +91 96192 18531.

Yes, there is, and it arrives sooner than most people expect. Everything so far in this section has been about what extra reeds cannot do for you. This page is about what they can do to you, which is a shorter list and a more useful one. A room can be overdosed, a bottle you like can be spent in a fraction of the time it should have lasted, and a bedroom at night is the least forgiving place in the house to get this wrong.
Quick answers — read this first
Can you put too many reeds in a diffuser? Yes, easily, and a small enclosed room is where it happens first. A bathroom, a powder room or a study concentrates fragrance naturally because there is very little air to dilute into and very little leaving through a shut door, so a bottle that reads pleasant with four sticks can read overpowering with eight. The signs are straightforward: the room stops feeling scented and starts feeling heavy, guests comment, and you find yourself opening a window. Correcting it takes one minute and costs nothing - pull sticks out, set them aside on a tissue, and the intensity falls within a few hours. Nobody needs to buy anything to fix this, and a fragrance you had begun to dislike is often a fragrance that was simply dosed too high for the room it was in.Do more reeds waste the oil? They spend it faster, which becomes waste when the extra intensity is not buying you anything you wanted. Reed count controls the rate at which oil evaporates, so roughly doubling the sticks roughly doubles the consumption, and a SOSA reed diffuser that lasts about 6 to 10 weeks moves toward the short end of that window rather than the long one. Now do the arithmetic that matters. If loading the reeds means you buy two Rs 749 bottles where one would have done, that is Rs 1,498 - and a Boond ultrasonic at Rs 899 with a water-based Hotel Collection bottle at Rs 299 is Rs 1,198, which is less money for an active machine that does the room job the extra reeds were never going to do.
Can a reed diffuser be too strong in a bedroom at night? It can, and it is worth taking seriously rather than pushing through.

The short answer
Short answer: Yes. Too many reeds in a small enclosed room make the space overpowering at close range and unpleasant to sit in, and correcting it is free - take sticks out. They also roughly double consumption, so a Rs 749 bottle heads for the short end of the usual 6 to 10 weeks; buying two bottles at Rs 1,498 costs more than a Boond at Rs 899 with a water-based Hotel Collection bottle at Rs 299, which is Rs 1,198 for an active machine. And in a bedroom at night, an overdosed room can disturb sleep for a sensitive person. A headache is a recalibration signal, not a tolerance problem: take reeds out. For a whole room, an ultrasonic from Rs 899; for strong scent where you sit, the waterless SOSA Safar Rs 3,999. WhatsApp +91 96192 18531.
The pick: keep the reed from ₹749 for ambience near where it stands; an ultrasonic from ₹899 with the water-based Hotel Collection from ₹299 when you want the whole room evenly; the SOSA Safar (₹3,999, waterless and cordless, three hotel-inspired blends included) when you want it strong and true in the space you sit in; the SOSA Vaayu (₹11,999) for a large or open-plan room.

In this guide
Nothing has gone wrong with your reed diffuser. A reed is a passive system: the oil climbs the sticks and evaporates at whatever rate your room's warmth and air movement allow, and no part of it pushes scent anywhere. That is exactly why it is lovely at arm's length and quiet across the room. What has changed is what you now want from it. Ambience near where the bottle stands is one job; a whole room that smells of it, or a strong true scent right where you sit, is a different job, and a different job needs a different tool. This guide explains the mechanism first, then tells you honestly which tool matches which wish.

Straight answer
Is there a point where adding reeds stops helping and starts making things worse?
Yes, and there are three separate ways it happens. 1. The room becomes overpowering rather than scented. Small enclosed spaces concentrate fragrance because there is little air to dilute into and little leaving, so a bathroom, a powder room or a study that was lovely with four sticks can be heavy and tiring with eight. The fix is free and immediate: pull reeds out, lay them on a tissue, and the level drops within hours. 2. The bottle empties for nothing. Reed count sets the evaporation rate, so doubling the sticks roughly doubles consumption, and a reed diffuser at ₹749 that lasts about 6 to 10 weeks moves toward the short end. Do the sum properly: two bottles instead of one is ₹1,498, while a Boond at ₹899 with a water-based Hotel Collection bottle at ₹299 is ₹1,198 - less money, for an active machine that actually does the room job. Three bottles at ₹2,247 is more than a Sukoon and a Hotel Collection at ₹2,198. 3. A bedroom at night is unforgiving. You breathe that air for seven or eight hours with the door shut, and a level that felt generous at nine in the evening can be too much at three in the morning - enough to disturb sleep for a sensitive person. Households include children, elderly relatives, pregnant family members and pets, so gentle dosing is the default and a headache is a recalibration signal, not a tolerance problem. Take reeds out; we would rather you did that than persevered. And remember what overdosing cannot buy. None of it adds reach, so if the real wish is a room that smells of it, that is an active ultrasonic from ₹899 or the waterless SOSA Safar at ₹3,999 for the space you occupy.

Three ways extra reeds stop helping and start costing
Comfort first, then money, then the bedroom - and the free correction that fixes all three.
1
Cost one
A room you cannot sit in comfortably is not a scented room
The first threshold is comfort, and it is crossed most often in the rooms where reeds work best. A small enclosed space does two favours for a fragrance at once: it gives it almost no air to dilute into, and behind a shut door it lets what evaporates accumulate for hours. A 5 by 7 bathroom under a 9 ft ceiling holds 35 x 9 = 315 cubic feet of air, which is only about 9 cubic metres once you divide by 35.3, so a bottle that reads beautifully with four sticks can be genuinely too much with eight in the same space. What overdosing feels like is worth naming, because people often blame the fragrance rather than the dose: the room stops smelling of something and starts feeling heavy, the scent is the first thing you notice on entering and it never fades into the background, and someone eventually opens a window. That is not a bad blend. That is a good blend at the wrong volume, and the correction is free - take sticks out, lay them on a tissue, and within a few hours the room settles.
Tip: the test is whether the fragrance recedes after a few minutes - a scent you never stop noticing is dosed too high.
2
Cost two
You are buying intensity you did not want at a price you did not intend
The second threshold is money, and it is the one nobody calculates until the bottle is empty. Reed count is a consumption control: more exposed wet surface means more oil leaving per hour, so roughly doubling the sticks roughly doubles the rate. A SOSA reed diffuser lasts about 6 to 10 weeks, and how you load it decides where in that range you land, which means a heavily loaded bottle is a bottle you replace considerably sooner. Now put real numbers on it, because they are more interesting than the principle. If loading the reeds turns one ₹749 bottle into two over the same stretch of time, you have spent ₹1,498. A Boond at ₹899 with a water-based Hotel Collection bottle at ₹299 is ₹1,198 - less money for an active, room-designed machine. Three bottles at ₹2,247 is more than a Sukoon with a Hotel Collection at ₹2,198. So the person loading reeds to chase a room is often outspending the honest upgrade while not getting it, and that is exactly the sentence we would want said to us.
3
Cost three
A bedroom at night is the least forgiving room in the house
The third threshold is the one that matters most and gets discussed least. A bedroom is a modest volume of air that you occupy with the door shut for seven or eight continuous hours, and a level of fragrance that felt generous at nine in the evening is a different proposition at three in the morning. For a sensitive person, an overdosed bedroom is genuinely enough to make sleep restless or to bring on a heavy head, and that is not a small thing to trade for a fragrance you could have at half the strength. Homes are also shared. Children, elderly relatives, pregnant family members and pets are in that air far longer than any guest, they cannot easily tell you it is too much, and their tolerance is not yours. So the default in a bedroom is gentle, always: fewer sticks than you would use in a hallway, the bottle not directly beside the pillow, and a willingness to remove reeds rather than acclimatise to them. If anyone reports a headache, treat it as a recalibration signal rather than a tolerance problem - take reeds out or move the bottle to another room. We make no health or therapeutic claims of any kind; this is simply how to dose a room you sleep in. And if what you wanted all along was to smell the fragrance from the bed rather than to fill the room with it, the waterless cordless SOSA Safar at ₹3,999 is a bedside answer that does not rely on saturating the air.
Tip: fewer sticks in a bedroom than anywhere else - you are in that air for eight hours, not eight minutes.
The SOSA principle
Reeds give you exactly one dial, and it is at the source. Dials can be turned too far. Turning this one up cannot buy reach, and it can very easily buy discomfort.
Overpowering in a small room, a bottle spent for nothing, and a bedroom that disturbs sleep - three real costs, none of which comes with a gain in distance.

The ladder from passive to active, in order - tap any image to see it on the store
Start where you already are. Reed diffusers from ₹749 are passive: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849 and Fresh Brew ₹849, with 130ml sizes from ₹1,249. They give you ambience near where the bottle stands, with no power, no noise and nothing that can fail, and they are still the right product for a bathroom, a bedside table, a study or a guest room. If you want the room itself to smell of it, that needs an active diffuser: Boond ₹899, Sukoon ₹1,899 or Megh ₹3,499 running the water-based Hotel Collection from ₹299 (100ml refill ₹999, or the Pack of 7 at 15ml for ₹1,799). That is the honest first upgrade for a single ordinary bedroom, and it costs less than the Safar. Its trade-off, in our own words: an ultrasonic mixes the fragrance with water, which adds humidity to the room, can dilute the scent, and in hard-water areas can leave a fine white dust on nearby surfaces. If you would rather have no water at all and want the scent strong and true in the space you actually occupy, the SOSA Safar ₹3,999 is waterless, cordless and rechargeable, diffusing pure undiluted oil by cold diffusion. For a large room or a connected open-plan space, the SOSA Vaayu ₹11,999 is the genuine whole-space answer at approximately 1000m³ of connected volume, and it is honestly more machine than a small bedroom needs.

The SOSA edit, passive to active
Whatever your room looks like, the logic is the same, and it has nothing to do with how big or smart your home is. A passive reed gives you scent near where it stands, and that is genuinely the right answer for a bathroom, a bedside table, a study or a guest room. An active diffuser moves scent into the air instead of waiting for the air to come and collect it, which is the only thing that turns "lovely next to the bottle" into "the room smells of it". Every SOSA product is made in India, cruelty-free and vegan, and a portion of every order supports girl-child education through Nanhi Kali. Here is where each one honestly belongs.

Which one matches what you actually want - ambience near the bottle, a whole room, or strong scent where you sit
| Product | What job it does | Why it does that job | Price |
|---|---|---|---|
| Reed diffusers (Morning Freshness ₹749, Garden Bloom ₹799) | Passive · ambience near where the bottle stands | No power, no noise, nothing to fail. Still the right product for a bathroom, a bedside table, a study or a guest room. Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml from ₹1,249 | from ₹749 |
| Boond or Sukoon + Hotel Collection | Active · one ordinary bedroom, evenly | The honest first upgrade for a whole room, and cheaper than the Safar. Runs the water-based Hotel Collection from ₹299 (100ml refill ₹999, Pack of 7 at 15ml ₹1,799). It mixes oil with water, so it adds humidity, can dilute the scent, and in hard-water areas can leave white dust | ₹899 / ₹1,899 + ₹299 |
| Megh (6L) | Active · a bigger room or a long unattended run | The 6L ultrasonic, same water-based Hotel Collection and the same water trade-offs, with a much larger tank for a whole evening on one fill | ₹3,499 |
| SOSA Safar ★ | Active and waterless · the personal space you occupy | Cordless, rechargeable 2000 mAh, cold diffusion of pure undiluted oil: no water, no dilution, no white dust. SOSA lists it as best for car, handbag, work desk, bedside, hotel and travel, and work-from-home. Ships with three hotel-inspired waterless blends. A personal-space diffuser with strong near-field projection, not a whole-room machine | ₹3,999 |
| SOSA Vaayu | Active and waterless · a large or open-plan room | Waterless cold-air to approximately 1000m³ of connected volume, Bluetooth app and timer, four hotel-inspired blends included. The genuine whole-space answer, and honestly oversized for a small bedroom | ₹11,999 |
Honest notes before you spend anything. A reed diffuser is passive, and its scent is strongest at the bottle. That is the mechanism working, not a fault, and not a sign you bought the wrong thing: oil climbs the reeds and evaporates, and nothing in the design pushes that scent across a room. More reeds increase evaporation, not reach. Adding sticks makes the air near the bottle stronger and empties the bottle faster; it adds no force to carry fragrance to the other side of the room, so you get a more intense spot and a shorter-lived diffuser. Placement optimises a passive system but cannot make it active. Moving the bottle out of a direct draught, away from an open window, up to roughly seated-nose height rather than on the floor, and into the part of the room you actually use, all genuinely help - and none of them convert passive diffusion into active diffusion. Ventilation and cleaning come first. If a room smells stale, damp or of last night's cooking, open it, air it and clean it; fragrance laid on top of that only makes a more complicated smell, and it never substitutes for either. Homes are shared. Households include children, elderly relatives, pregnant family members and pets, all of whom breathe this air far longer than a visitor does, so gentle dosing is the default and the settings we suggest are lower than any machine can run. Anyone reporting a headache is a recalibration signal, not a complaint to argue with: turn it down or turn it off, and tell us. The Safar and the Vaayu run waterless oil and each ship with their own blends; the Hotel Collection bottle is water-based and belongs in the ultrasonic machines only, and the two formats are not interchangeable. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house, not affiliated with or endorsed by any hotel brand.

A note from Sonal
There is a difference between a fragrance being good and a fragrance reaching you, and almost nobody is told what it is. When someone writes to me and says the reed diffuser smells wonderful up close but they cannot smell it from the bed, my first answer is always the same: nothing is wrong, and you did not buy the wrong thing. A reed diffuser is a passive object. It holds oil, the reeds draw it up, the room's warmth and air take it away at their own pace. It has no way of carrying scent to you, and it was never built to.
So the real question is not which fragrance is stronger. It is which job you want done. If you want a quiet, pleasant presence in the corner of a bathroom or beside a bed, a reed is still the most elegant thing I sell, and I would rather you kept it than replaced it. If you want the whole room to smell of something when you walk in, that needs a machine that actively moves scent into the air, and the honest first step there is one of our ultrasonics, which costs less than our waterless diffuser does. If you want it strong and true right where you sit or sleep, with no water and no dilution, that is the Safar. And if your living space is genuinely large or open-plan, that is the Vaayu, which I will happily tell you is far too much machine for a 10 by 12 bedroom.
I trained at ISIPCA in Versailles and I have had this conversation hundreds of times, and I would much rather talk someone out of a purchase than sell them a disappointment. Message us on WhatsApp at +91 96192 18531 with your room's approximate size and a line about where you actually sit or sleep in it - the bed, the desk, the sofa, the corner you read in - and we will tell you which of these you need, including when the answer is none of them. I read those messages myself. Everything is made in India, cruelty-free and vegan, and a part of every order funds girl-child education through Nanhi Kali. Your room gets a memory; a girl gets a classroom.
Frequently asked questions
How do I know if my room is overdosed rather than the fragrance being wrong?
Use the recede test, because it separates the two cleanly. A correctly dosed room announces itself pleasantly when you walk in and then fades into the background within a few minutes as your nose adapts. An overdosed room never fades: you keep noticing it, it feels heavy rather than pleasant, and you find yourself wanting air. If your fragrance passes the test at four sticks and fails it at eight, the blend was never the problem and you have simply been running it too high for that room. Try it at half the reeds for a week before you conclude you dislike the scent. If it still feels wrong at a gentle dose, then it genuinely is not the right register for you and that is a fair thing to discover. Either way, nothing about this is fixed by buying a stronger oil, and we would rather you tested the dose than replaced a bottle you might love.
If I take reeds out, do I put the same ones back later?
You can, and it is worth doing it thoughtfully. Lay the removed sticks on a tissue or in a small dish rather than on furniture, because fragrance oil can mark polished wood and painted surfaces. They will keep for a while and can go back in when the bottle has thinned and you want the intensity up again, which makes them a useful way to manage a diffuser across its life: run fewer sticks while the oil is fresh and strong, add sticks later as the fragrance quietens. That single habit gets you a more even experience across the 6 to 10 weeks a bottle runs, rather than a strong start and a faint finish. What it does not do, and it is worth repeating so you do not test it in vain, is change how far the fragrance reaches. Removing and adding sticks moves intensity up and down at the source only.
Someone in my house gets a headache from it. Should they get used to it?
No. Take reeds out or move the bottle, and treat what they told you as information rather than something to negotiate with. A headache is a recalibration signal, and the sensible response is to reduce the dose and see whether it settles, then reduce again if it does not. Start by halving the sticks, move the bottle out of the room they spend most time in, and give it a couple of days. If it persists at a gentle dose, take the fragrance out of that room entirely - there is no version of home fragrance that is worth someone feeling unwell in their own house. This applies with extra weight where there are children, elderly relatives, pregnant family members or pets, all of whom are breathing that air far longer than a visitor and cannot easily opt out. Ventilation and cleaning come first in any case, and fragrance is the finishing layer on air that is already fresh.
Is a smaller number of reeds a waste of the oil I paid for?
Not at all - the oil is not being wasted, it is being spent at a slower rate, and every bit of it still evaporates eventually. Running four sticks instead of eight gives you a gentler room and a longer life from the same Rs 749, which for most people is better value rather than worse. The only scenario where fewer reeds genuinely costs you something is if the fragrance becomes so faint that you stop noticing it even when standing beside the bottle, and at that point the honest answer is to add a stick or two, not to conclude the bottle is finished. Think of reed count as a volume knob you set once for the room and adjust as the bottle ages. The knob has an upper limit set by comfort and a lower limit set by whether you can smell it where you sit, and the right setting lives between the two.
I have loaded every reed I own and my room still is not scented. What should I do?
Take some of them out, first, because you are almost certainly overdosing the corner while gaining nothing across the room, and then think about the money rather than the sticks. What you have proved is that the intensity dial is turned to maximum and the outcome you want is not on that dial. Reach in a passive system is not set by how much fragrance the source releases; it is set by whether anything is moving air. For a single ordinary bedroom, an ultrasonic is the honest first step at Rs 899 for a Boond with a water-based Hotel Collection bottle at Rs 299, which is Rs 1,198 in total and less than two reed bottles - the fair trade-offs being added humidity, some dilution and white dust in hard-water areas. For strong, undiluted scent right where you sleep, the waterless Safar is Rs 3,999. Message us on WhatsApp with your room size and we will tell you which, including when the honest answer is to change nothing.

- Brand: Founder story — why SOSA exists
Editorial standards & sources
About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the passive-versus-active reasoning applies to any brand's products.Facts verified August 2026: A reed diffuser is a passive system - oil travels up the reeds by capillary action and evaporates at the rate the room's temperature and air movement allow, so concentration is highest at the bottle and falls away with distance. A SOSA reed diffuser lasts about 6 to 10 weeks. Reed prices: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml sizes from ₹1,249. An active diffuser adds energy to move fragrance into the air. SOSA's ultrasonic machines are Boond (₹899), Sukoon (₹1,899) and Megh 6L (₹3,499); they run the water-based SOSA Hotel Collection, 15ml ₹299, 100ml refill ₹999, Pack of 7 at 15ml ₹1,799. An ultrasonic mixes fragrance with water, which adds humidity to the room, can dilute the scent, and in hard-water areas can leave white dust. The SOSA Safar (₹3,999) is a waterless, cordless, rechargeable cold-diffusion perfume diffuser with a 2000 mAh battery, diffusing pure undiluted oil with no water and no white dust; SOSA's own copy lists it as best for car, handbag, work desk, bedside, hotel and travel, work-from-home and gifting. It ships with three hotel-inspired waterless blends, chosen as one of three bundles: Ritz-Carlton Inspired, Westin Inspired and 1 Hotels Inspired; St. Regis Inspired, Shangri-La Inspired and Four Seasons Inspired; or W Hotels Inspired, Ritz-Carlton Inspired and Westin Inspired. No square-foot or cubic-metre coverage figure is published for the Safar, so none is stated here or anywhere else by us; it is a personal-space diffuser, not a whole-room machine. The SOSA Vaayu (₹11,999) is a waterless cold-air system covering approximately 1000m³ of connected volume, with a Bluetooth app and timer, and it ships with four hotel-inspired waterless blends included in the box. Format distinction: the Safar and the Vaayu run waterless oil and each arrive with their own blends, while the ₹299 Hotel Collection bottle is water-based and goes into the ultrasonic machines only. The two formats are not interchangeable. Scent perception is personal and varies between people in the same room, and coverage figures assume connected air volume rather than closed doors. Ventilation and cleaning come first; fragrance is an addition to a well-kept room and never a substitute for either, and we make no health, therapeutic or air-purification claims. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any hotel brand. Made in India, cruelty-free and vegan. A portion of every order supports girl-child education through Nanhi Kali. Questions about a specific room are answered on WhatsApp: +91 96192 18531.
