Founder Diaries · Reed Diffuser & Home Fragrance Gifting
By Sonal Sahani · ISIPCA Versailles 11 min read Updated September 2026
Two variables are being carried around as one, which is why the decision keeps sliding. Size is a question about places. Usage is a question about weeks. They pull on different parts of the published range, and only one of them has a number attached to it - because SOSA publishes life per size and publishes no coverage figure for a reed diffuser at all. Separate them and the choice between one bottle, a combination and something larger stops being a judgement call and becomes two small readings you can actually make.
SOSA Garden Bloom reed diffuser, Rs 799
SOSA reed diffuser · 50ml and 130ml · weeks published, reach not from ₹749 →
The two published numbers this decision runs on. A SOSA reed diffuser is ₹749 to ₹849 in 50ml, published to last 6 to 8 weeks, and ₹1,249 to ₹1,349 in 130ml, published to last 14 to 18 weeks - same glass, same 6 fibre reeds, more liquid. No coverage or room-size figure is published for a reed diffuser, so size of house is a count of bottles rather than a sum.
Quick answers — read this first
How does the size of a villa decide how many reed diffusers to give? Not through a coverage figure, because there is not one. SOSA publishes no coverage, room-size or square-footage figure for a reed diffuser, so size enters the decision only as a count: how many places do you want a bottle standing in. One bottle is one place. A duo set from ₹1,498 is two bottles of the same size, so two places, and separate bottles at ₹749 to ₹849 each are as many places as you buy.

How does usage decide the size of the bottle? Through the published life, which is the number that exists. The 50ml lasts 6 to 8 weeks at ₹749 to ₹849; the 130ml lasts 14 to 18 weeks at ₹1,249 to ₹1,349. A home visited most weekends and a home opened twice a season sit at opposite ends of that. The figures are stated as elapsed weeks, and SOSA publishes nothing about how a closed-up house changes them, so no adjusted number is offered here.

When is a larger scenting system the right answer instead? When the person deciding owns the building. Vaayu at ₹11,999, Angaan at ₹25,999 and Meenar at ₹38,500 are property-scale machines that have to be installed and run, which makes them a project rather than a gift. For a guest, the reed format is the one that needs no socket, no plumbing and nothing switched on, whatever the size of the house.
The short answer
Short answer: Treat size and usage as two separate readings. Size is a count of places, because SOSA publishes no coverage figure for a reed diffuser. Usage is a count of weeks: 50ml lasts 6 to 8 weeks at Rs 749 to Rs 849, 130ml lasts 14 to 18 weeks at Rs 1,249 to Rs 1,349, and a duo set from Rs 1,498 is two bottles.
The pick: For a weekend property in regular use, a 130ml reed diffuser, ₹1,249 to ₹1,349 - published at 14 to 18 weeks, one place, nothing to switch on.
Why: Usage is the variable with a published number attached, so it decides the size; size of house only decides how many bottles you buy.
Sending something when somebody is having a hard time - at a glanceKeep it small - candle ₹399, attar ₹379, car scent ₹449For their home - reed diffuser ₹749, nothing to switch onSay the words yourself - no card goes in the parcelNever - a parcel instead of turning up
A gift cannot change how somebody's week went, and a page that suggests otherwise is not worth reading. What a small parcel does is tell a person you were thinking about them on a day when nothing made you - which is a real thing to say, and worth saying. Keep it small, because a large one asks somebody already short of energy to produce a reaction, and send the words separately, because the object cannot carry them.
Straight answer
How should the size and usage pattern of a villa, farmhouse or weekend home decide whether I gift one reed diffuser, a combination, or a larger scenting system?
Take them one at a time, because they answer different questions and merging them is what makes this feel unresolvable. Usage first, because it is the variable with a published number. A SOSA reed diffuser publishes its life per size: the 50ml lasts 6 to 8 weeks and costs ₹749 for Morning Freshness, ₹799 for Garden Bloom and Evening Calm, and ₹849 for Mountain Breeze and Fresh Brew; the 130ml lasts 14 to 18 weeks and costs ₹1,249 to ₹1,349. Same refillable glass bottle, same 6 fibre reeds, same coconut-derived CCT carrier - phthalate-free, paraben-free and IFRA-compliant, made in India; the difference is liquid and therefore weeks. A house used most weekends and a house opened twice a season are at different ends of that, and it is a reading you can make without guessing. One honesty note: those figures are elapsed weeks, and SOSA publishes nothing about how a shut-up house between visits changes them, so no adjusted figure appears here. Size second, and it does not work the way people expect. There is no coverage number to divide into a floor plan - SOSA publishes no coverage, room-size or square-footage figure for a reed diffuser, and a reed diffuser is a passive bottle with no fan and no range. So size enters only as a count of places. One bottle is one place. The published combination is the duo set: Day & Night at ₹1,498, Fresh & Grounded at ₹1,548 and Warmth & Bloom at ₹1,598 in 50ml x 2, or ₹2,498 to ₹2,598 in 130ml x 2, and those three pairings are the entire set range, none is composed to order, and both bottles in a set are the same size. Third, the larger systems, named so you can set them aside deliberately. Vaayu at ₹11,999, Angaan at ₹25,999 and Meenar at ₹38,500 are property-scale machines that have to be installed and run - the right category for an owner scenting their own building, the wrong one for a guest arriving on a Friday. And the limit that sits over all of it: how a scent behaves in that particular property is not something anybody can tell you in advance, and nothing here can tell you how the gift will be received either. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Usage picks the size. Size of house picks the number of bottles. Only the first of those has a published figure behind it, and pretending otherwise is how these decisions go wrong.
The two readings in one line: 50ml ₹749 to ₹849 at 6 to 8 weeks, 130ml ₹1,249 to ₹1,349 at 14 to 18 weeks for duration, and one more bottle for each extra place.
See SOSA reed diffusers from ₹749

Two variables, taken separately, and the one that has no published number

Three readings in this sequence. The third one only applies to one of the people who might be asking.

1
Reading one
Usage, which converts directly into a published number
This is the easy half, and it is the half most people skip because it feels less important than the floor plan.

A property in regular use - most weekends, people in and out - is a property where a bottle is doing something on more occasions. The 130ml at ₹1,249 to ₹1,349, published to last 14 to 18 weeks, spans a long run of those.

A property used occasionally - a few times a season, long gaps between - is where the 50ml at ₹749 to ₹849, published to last 6 to 8 weeks, is often the more honest object, because you are not buying weeks that nobody is in the house for.

And the honest gap in the middle of that sentence. The published figures are elapsed weeks. SOSA publishes nothing about how a closed house, or a hot shut room, changes them, and this page will not invent a correction. If it matters to your decision, the bottle is refillable and refills are ₹2,399 for 300ml and ₹3,499 for 500ml in all five scents - that is a published fact, unlike any adjustment to the weeks.
Tip: Usage is the variable with a number attached, so let it choose the size of the bottle.
2
Reading two
Size, which is a count of places and not a coverage sum
Here is where the question usually gets asked in an unanswerable form: how many square feet does one bottle handle. SOSA publishes no coverage, room-size or square-footage figure for a reed diffuser, in any unit, so there is no sum to do and any page offering you one has made it up.

What is true about the object is simpler. A reed diffuser is a passive glass bottle with 6 fibre reeds and no fan, no socket and no switch. Nothing is pushed anywhere. It stands in one spot and the scent is in the air around it, and how far that goes depends on ceiling height, doorways, fans and cross-draughts in a house SOSA has never seen.

So size of house becomes a decision about count. One bottle, one place. Two bottles, two places - which is what a duo set is: Day & Night ₹1,498, Fresh & Grounded ₹1,548, Warmth & Bloom ₹1,598 in 50ml x 2, or ₹2,498 to ₹2,598 in 130ml x 2. Those three are the whole set range, none is composed to order, and both bottles in a set are the same size. Beyond two, it is separate bottles.
3
Reading three
When the answer is a machine, and who that answer belongs to
There is a real category above the bottles and it deserves naming rather than a polite silence. SOSA Vaayu at ₹11,999 is a waterless cold-air machine. Angaan at ₹25,999 works with HVAC. Meenar is ₹38,500. These are property-scale machines: they have to be installed and they have to be run, and the decision to put one into a building is the owner's decision about their own property.

Which is exactly why they are the wrong thing for a guest to arrive with. A gift that has to be fitted turns into a project somebody now owns, in a house you are visiting for two nights. The reed format sits at the other end: no flame, no socket, no switch, no batteries, nothing to demonstrate, and it finishes by itself.

The ultrasonic machines sit in between and are worth knowing about - Boond ₹899, Sukoon ₹1,899 and Megh ₹5,999 - though each needs a socket, water and regular refilling, so each is equipment that lives somewhere between uses. And on presentation, whichever you choose: the only branding is a custom label or logo on product. There is no custom box, no printed sleeve and no insert card. There is no carton, no ribbon and no message card. Ask about anything else on WhatsApp at +91 96192 18531.
Tip: A machine is a decision about a building, and a bottle is a decision about a visit.
SOSA Evening Calm reed diffuser, lavender and chamomile
The property that makes this work as a first-visit gift
A consumable is not an object somebody has to keep
The real fear behind a first-visit gift is not that it will be disliked. It is that it will have to be kept - displayed, dusted, and eventually explained if it disappears. A decorative object carries all of that into a home you have never seen. A reed diffuser does not, because it ends by itself. The published life makes that concrete: 6 to 8 weeks for the 50ml at ₹749 to ₹849, and 14 to 18 weeks for the 130ml at ₹1,249 to ₹1,349. It also asks nothing of anybody on the day - no flame, no socket, no switch, nothing to demonstrate. And if they do like it, the glass bottle is refillable, with refills at ₹2,399 for 300ml and ₹3,499 for 500ml in all five scents.
See SOSA reed diffusers from ₹749 →
Work it out in this order
The two readings, in the order that makes the decision fall out
  1. Read usage first: regular use suits 14 to 18 weeks, long gaps suit 6 to 8.
  2. Read size second, as a count of places - there is no coverage figure at all.
  3. One place is one bottle; two places is a duo set from Rs 1,498.
  4. Machines from Rs 11,999 are the owner's decision, not a guest's gift.
The SOSA principle
People treat a large house as a reason to spend more, and it is really only a reason to buy more places. The size of the bottle answers a question about time, and no amount of money in a single bottle turns it into something with a radius.
That is why the published range is more useful than it looks: it separates duration from count, which is exactly the split this decision needs.

Scents for a second home, and the figures SOSA does not publish

Five scents, and on a second home the register usually follows the property rather than the person. Morning Freshness at ₹749 is Malabar lemon and mint. Garden Bloom at ₹799 is British rose and night-blooming jasmine. Evening Calm at ₹799 is lavender and chamomile. Mountain Breeze at ₹849 is Himalayan pine, sage and cedar, the green and woody one. Fresh Brew at ₹849 is Coorg coffee and Kerala vanilla. All five are phthalate-free, paraben-free and IFRA-compliant, made in India, with 6 fibre reeds in a refillable glass bottle, and the pages advise flipping the reeds roughly once a week to refresh projection, stating the interval a little differently from one scent to the next.

The SOSA gift edit
Four usage patterns, and what each one points at
The option Who it suits, and where it fails
Used most weekends, one main room · ₹1,249 to ₹1,349 A 130ml, published to last 14 to 18 weeks, standing in the room where people actually sit. One place for a long run. It does nothing for the bedrooms, and no coverage figure is published that would suggest otherwise.
Opened a few times a season · ₹749 to ₹849 A 50ml, published to last 6 to 8 weeks. You are not buying weeks the house stands empty for. The limit is honest rather than technical: SOSA publishes nothing about how a closed-up house changes those weeks.
Two rooms in regular use · ₹1,498 to ₹1,598 A duo set, two bottles of the same size, which is the only combination SOSA publishes. No set is composed to order, so the pairing is fixed - two bottles you choose yourself means two single bottles instead.
The owner scenting the whole property · ₹11,999 to ₹38,500 Vaayu, Angaan and Meenar, which are property-scale machines that have to be installed and run. The right category for somebody deciding about their own building, and not something a guest should arrive holding.
SOSA reed diffuser duo set, two bottles in one box
When one bottle is not quite the right size of gesture
The three duo sets - and they are the only three
Several of these situations want something a little larger without becoming complicated: a first formal visit, a weekend stay, a household that has just hosted you for a week. The published answer is a duo set - two bottles in one box. Day & Night pairs Morning Freshness with Evening Calm at ₹1,498; Fresh & Grounded pairs Morning Freshness with Mountain Breeze at ₹1,548; Warmth & Bloom pairs Fresh Brew with Garden Bloom at ₹1,598. In 130ml x 2 they are ₹2,498, ₹2,548 and ₹2,598. Those three pairings are the entire set range, none is composed to order, and both bottles in a set are the same size. On presentation, be straight with yourself before you order: custom label or logo on product is the only branding SOSA offers - there is no custom box, no printed sleeve and no insert card.

Two neighbouring formats, so the map is complete. SOSA attars from ₹379 are worn on the body, so they answer a question about a person rather than about a property - useful to name here precisely because a page about villas should not quietly swap the two. Candles from ₹399 are consumed like a reed diffuser but need a flame and somebody in the room, which makes them a different kind of object to leave in a house used in bursts. And refills at ₹2,399 for 300ml and ₹3,499 for 500ml exist in all five scents, which is worth knowing when the gift is for a property somebody will keep coming back to.

SOSA reed diffuser 50ml, from Rs 749
₹749 to ₹849 across five scents, published to last 6 to 8 weeks. Large enough to be a proper object, small enough that the household never has to find permanent space for it.
from ₹749
SOSA reed diffuser 130ml, from Rs 1,249
₹1,249 to ₹1,349, published to last 14 to 18 weeks. The same object with more of it - the honest way to make the gesture larger without making it more complicated.
from ₹1,249
SOSA reed diffuser duo set, from Rs 1,498
Two bottles in one box, ₹1,498 to ₹1,598 in 50ml and ₹2,498 to ₹2,598 in 130ml. Three published pairings, and those three are the whole range - none is composed to order.
from ₹1,498
Why this category answers a first-visit problem at all
It finishes. That is the entire argument, and it is a fact rather than a claim.
The fear behind almost every first-visit gift question is the same one: that you will hand somebody an object they now have to keep. A vase has to be displayed. A framed thing has to go on a wall. A decorative piece has to survive somebody's taste, and you have never seen the room. A reed diffuser is a consumable, so it carries none of that. It sits somewhere for a while and then it is gone, and nobody has to explain why it is no longer out. The published life makes that concrete rather than vague: 6 to 8 weeks for the 50ml (₹749 to ₹849) and 14 to 18 weeks for the 130ml (₹1,249 to ₹1,349). It also asks nothing of the household on the day: no flame, no socket, no switch, no batteries and nothing to explain at a front door - it works by standing there, with 6 fibre reeds in a refillable glass bottle, on a CCT coconut-derived carrier that is phthalate-free, paraben-free and IFRA-compliant, made in India. Flip the reeds roughly once a week to refresh projection. What anybody makes of being given one is not something SOSA can tell you, and no page should pretend otherwise.

A bigger bottle buys weeks. A second bottle buys a room. There is no third thing a reed diffuser can be bought to do.
— Sonal Sahani, SOSA

The SOSA gifting range

Two questions settle almost every reed diffuser gift, and the first one is not price. How big is the room it is going into? A 50ml suits a bedroom, a study, a hallway or a first diffuser; a 130ml suits an open-plan living and dining area, and it is genuinely too much for a small closed bedroom. Then: how much do you actually know about their taste? The less you know, the less declarative the scent should be - Morning Freshness is the safest of the five for a home you have never stood in, and Fresh Brew coffee-vanilla is the strongest opinion in the range. Price follows those two answers rather than leading them.

The SOSA range, sorted by how much it asks of the person receiving it
Start from what the gift demands, not from what it costs
Product What it is What it is for Price
SOSA reed diffuser - 50ml The first-visit size ₹749 to ₹849 across five scents. Published to last 6 to 8 weeks, with 6 fibre reeds and a refillable glass bottle. No flame, no socket, nothing to switch on from ₹749
SOSA reed diffuser - 130ml The larger bottle ₹1,249 to ₹1,349, the same five scents. Published to last 14 to 18 weeks - the honest choice when the gesture needs weight rather than a second bottle from ₹1,249
SOSA reed diffuser duo sets Two bottles, one box Day & Night ₹1,498, Fresh & Grounded ₹1,548, Warmth & Bloom ₹1,598 in 50ml x 2; ₹2,498 to ₹2,598 in 130ml x 2. These three pairings are the whole set range from ₹1,498
SOSA reed diffuser refills If they like it, it continues ₹2,399 for 300ml and ₹3,499 for 500ml, published for all five scents. The bottle is refillable glass, so the gift does not have to be a one-off from ₹2,399
SOSA attars Worn, not placed From ₹379 in 3ml. An attar is a personal gift and a reed diffuser is a household one - which is the distinction most first-visit questions are really about from ₹379
SOSA candles They need a flame From ₹399. Warm and traditional, but somebody has to light them and stay with them, which is a real consideration in a home you do not know from ₹399
SOSA ultrasonic machines Water-based, plugged in Boond ₹899, Sukoon ₹1,899, Megh ₹5,999 - they need a socket, water and regular refilling. That is a commitment to hand somebody on a first visit from ₹899

A reed diffuser is a consumable, which is the whole argument for it as a first-visit gift. It is not a permanent object competing for a shelf in somebody else's home, and it needs no flame, no socket, no switch and no explanation at a front door. Published life is 6 to 8 weeks for the 50ml and 14 to 18 weeks for the 130ml, with 6 fibre reeds per bottle, a refillable glass bottle, and a CCT coconut-derived carrier that is phthalate-free, paraben-free and IFRA-compliant, made in India. Flip the reeds roughly once a week to refresh projection - the product pages state the interval slightly differently, between every three and every seven days. Fragrance adds a scent to a room; it does not remove, neutralise, mask or purify an odour and it does not clean the air. Prices above are published retail prices; bulk orders are welcome and custom label or logo on product is available, with quantities settled on WhatsApp at +91 96192 18531. SOSA is an Indian fragrance house based in Pune, sending orders across India. A portion of every order supports girl-child education through Nanhi Kali.

The honest spec sheet
What the SOSA reed pages publish, and what they do not
Everything below is on the live product pages. Anything not on this list is not something a page like this should state.
  • The five scents and their prices - Morning Freshness, Malabar lemon and mint, ₹749 and ₹1,249; Garden Bloom, British rose and night-blooming jasmine, ₹799 and ₹1,299; Evening Calm, lavender and chamomile, ₹799 and ₹1,299; Mountain Breeze, Himalayan pine, sage and cedar, ₹849 and ₹1,349; Fresh Brew, Coorg coffee and Kerala vanilla, ₹849 and ₹1,349.
  • Published life - 6 to 8 weeks for the 50ml and 14 to 18 weeks for the 130ml, stated on all five pages. This is newer and more specific than the flat figure earlier SOSA writing used.
  • The format - 6 fibre reeds per bottle rather than rattan, a refillable glass bottle, and a CCT carrier (caprylic/capric triglyceride, coconut-derived) that is phthalate-free, paraben-free and IFRA-compliant. Made in India, formulated by Sonal Sahani, ISIPCA Versailles trained. No flame, no socket, no switch.
  • Flip the reeds roughly once a week to refresh projection. The pages state it slightly differently - once a week on three of them, every five to seven days on one, every three to five on another - so treat it as about weekly rather than as a rule.
  • Duo sets and refills - three published pairings at ₹1,498, ₹1,548 and ₹1,598 in 50ml x 2 and ₹2,498 to ₹2,598 in 130ml x 2, and refills at ₹2,399 for 300ml and ₹3,499 for 500ml in all five scents. Those three pairings are the entire set range and none is composed to order.
  • Not published, and therefore never stated here: any coverage or room-size figure for a reed diffuser; how a scent behaves in a particular home; any bulk rate, minimum quantity, price break or lead time; any presentation packaging beyond a custom label or logo on product; and anything whatsoever about how a gift is received. Those go to WhatsApp +91 96192 18531.

A note from Sonal

A particular kind of message arrives on our WhatsApp, usually in the evening, usually slightly rushed. I am going to his parents' place on Sunday. I have never met them. I cannot go empty-handed and I have no idea what they like. It is one of the few gifting questions where the person is not really shopping. They are trying not to get something wrong in front of people whose opinion they have decided matters.

So the useful thing is not a recommendation, it is a subtraction. Most of what goes wrong with a first-visit gift is permanence. A decorative object has to be kept, displayed, and eventually explained if it is not. Food runs into what people eat. Anything personal runs into taste you have not earned the right to guess at yet. What is left is the category that ends by itself, and that is genuinely why a reed diffuser keeps coming up in those messages.

The part I would want you to hold on to is the least romantic part. The 50ml is published to last six to eight weeks, and the 130ml fourteen to eighteen. It has no flame, no plug and no switch, so nobody has to be shown how it works while their family stands in a doorway. It is a glass bottle and six fibre reeds, and it does the whole job by standing on a surface.

And the part I will not pretend about: I cannot tell you how anybody will take it. Nobody selling you a gift can, and the ones who promise it are selling you reassurance rather than a product. What I can tell you is what the object is, how long it lasts and what it asks of the person receiving it - which is very little. What that is worth on a Sunday afternoon in somebody's living room is yours to judge, not mine.

Frequently asked questions

How do I work out how many diffusers a large villa needs?
Not from a coverage figure, because SOSA publishes no coverage, room-size or square-footage figure for a reed diffuser in any unit. A reed diffuser is a passive bottle with no fan and no range, so the practical method is to count the places you want one standing in: one bottle per place, or a duo set at Rs 1,498 to Rs 1,598 for two places with both bottles the same size.
Does a weekend home need a bigger bottle or a smaller one?
That is the usage reading, and it has published numbers behind it: the 50ml lasts 6 to 8 weeks at Rs 749 to Rs 849 and the 130ml lasts 14 to 18 weeks at Rs 1,249 to Rs 1,349. Regular use across a season points at the larger bottle; long gaps between visits often make the smaller one the more honest object. Those figures are elapsed weeks, and SOSA publishes nothing about how an empty house changes them.
Is a combination better than one bottle for a house with many rooms?
A combination is two bottles rather than a stronger one. The three published duo sets are Day and Night at Rs 1,498, Fresh and Grounded at Rs 1,548 and Warmth and Bloom at Rs 1,598 in 50ml x 2, or Rs 2,498 to Rs 2,598 in 130ml x 2. None is composed to order and both bottles in a set are the same size. Beyond two places, it is separate bottles rather than a set.
When does a larger scenting system make sense?
When the person choosing it owns the property. Vaayu at Rs 11,999, Angaan at Rs 25,999 and Meenar at Rs 38,500 are property-scale machines that have to be installed and run, which makes them a commitment rather than a present. For a guest, the reed format needs no socket, no plumbing and nothing switched on, whatever the size of the house.
Will a reed diffuser be noticeable in a double-height living room?
Nobody can tell you that in advance, and this page will not pretend to. SOSA publishes no coverage or room-size figure for a reed diffuser, and how a scent behaves depends on ceiling height, doorways, fans and cross-draughts in a house nobody here has seen. What is published is the object and its life: 6 fibre reeds in a refillable glass bottle, 6 to 8 weeks in 50ml and 14 to 18 weeks in 130ml.
SOSA fragrance gift
Take the next step
Read usage for the size, read the house for the number of bottles
The 50ml at ₹749 to ₹849 for a property used in bursts - 6 to 8 weeks published. The 130ml at ₹1,249 to ₹1,349 for one in regular use - 14 to 18 weeks. A duo set from ₹1,498 when two rooms should each have one, both bottles the same size. Tell SOSA on WhatsApp how often the house is used and how many rooms you have in mind, and you will get one straight answer rather than a catalogue.
Not sure which one suits the person you are buying for? Send SOSA their age, whether they drive, whether they like their home scented and your budget on WhatsApp, and you will get an honest answer - including when the cheaper product is the better gift.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the gift-choosing reasoning applies to any brand.

Specifications verified from the live SOSA product pages, September 2026: SOSA reed diffusers are published in five scents and two sizes. Morning Freshness, Malabar lemon and mint, is ₹749 in 50ml and ₹1,249 in 130ml. Garden Bloom, British rose and night-blooming jasmine, and Evening Calm, lavender and chamomile, are ₹799 and ₹1,299. Mountain Breeze, Himalayan pine, sage and cedar, and Fresh Brew, Coorg coffee and Kerala vanilla, are ₹849 and ₹1,349. Published longevity is 6 to 8 weeks for the 50ml and 14 to 18 weeks for the 130ml. Every bottle is supplied with 6 fibre reeds rather than rattan, in a refillable glass bottle, on a CCT carrier - caprylic/capric triglyceride, coconut-derived - that is phthalate-free, paraben-free and IFRA-compliant, made in India. The product pages advise flipping the reeds to refresh projection and state the interval slightly differently, between once a week and every three to seven days, so no single interval is given here as a rule. Three duo combo sets are published: Day & Night at ₹1,498 in 50ml x 2 and ₹2,498 in 130ml x 2, Fresh & Grounded at ₹1,548 and ₹2,548, and Warmth & Bloom at ₹1,598 and ₹2,598; those three pairings are the entire set range and none is composed to order. Reed diffuser refills are ₹2,399 for 300ml and ₹3,499 for 500ml, published for all five scents. For comparison: SOSA attars are ₹379 to ₹399 in 3ml, rising to ₹1,149 to ₹1,199 in 12ml, and are worn rather than placed; SOSA candles start at ₹399 and require a flame; the ultrasonic machines Boond ₹899, Sukoon ₹1,899 and Megh ₹5,999 are water-based and need a socket, water and regular refilling. What is not published, and is therefore not stated here: any coverage, room-size or square-footage figure for a reed diffuser; how a scent behaves in any particular home; any shelf life, oil concentration or evaporation rate; any bulk rate, minimum quantity, price break or lead time; and any presentation packaging beyond a custom label or logo on product. Limits of this guide: fragrance adds a scent to a room. It does not remove, neutralise, mask or purify an odour, it does not clean the air, and no SOSA product makes any health, antibacterial or air-purifying claim. No claim is made anywhere on this page about mood, stress, calm, sleep or wellbeing; where a product is named Evening Calm or Mountain Breeze that is a product name and not a claim about its effect. No claim is made about how any gift will be received. Nothing here states or implies that a gift will impress anybody, be appreciated, create a good impression or affect any relationship; SOSA publishes no information of that kind and none is invented here. No statement is made about what any community, religion or family customarily eats, drinks or gives, and no etiquette rule is presented as a fact - the reasoning offered is reasoning the reader can check against their own situation. No rating, review count or customer name from any product page is cited, and no competitor or category of competing product is characterised. Bulk orders are welcome and custom label or logo on product is available; that is the only branding option, and quantities are settled on WhatsApp. SOSA Home & Body is an Indian fragrance house based in Pune, Maharashtra, sending orders across India, with no shop, showroom, stockist, counter or warehouse in any other city. Prices and availability are subject to change - see the live product pages.
