Founder Diaries · Reed Diffuser & Home Fragrance Gifting
Is a small passive bottle really not enough in a room like that? It is not that it fails - it is that it is doing a different job. A passive bottle scents the air immediately around itself, and in a tall room most of the air is above it. That makes a reed diffuser from ₹749 a good gift for a study or a bedroom and an awkward one for a two-storey volume.
Does the square-footage figure mean the same thing in a tall room? Not exactly, and it is worth being straight about it. The published figure is a volume - up to 1000 m3 - and the square-footage equivalent assumes ceilings of the ordinary kind. A double-height room holds far more air over the same plan, and SOSA does not publish how that changes the arithmetic, so ask on WhatsApp rather than trust a conversion.

The instinct in a room like this is to look for something with presence, and it is the wrong instinct twice over. Presence is a visual quality and the visual scheme is finished. More usefully: the thing a double-height room has more of is air, and almost nothing in home fragrance publishes a number about air at all. One product does, and the number it publishes is a volume rather than an area - which turns out to be the most useful sentence on this page, and the one that stops it overpromising.
The one product in the range that publishes a figure for air rather than for a surface. SOSA Vaayu, ₹11,999 - waterless cold-air diffusion, a dry residue-free mist, published for up to 1000 m3, quoted as about 2,000 to 3,000 sq ft of connected air at ordinary ceiling heights, with a 400ml tank, app and button control, 1, 4, 8 or 24-hour windows and operation under 38 dB. Four 100 ml fragrances in the box.

What suits a double-height living room that opens into other spaces? Something rated for a volume rather than for a table. SOSA Vaayu at ₹11,999 publishes up to 1000 m3, stated as about 2,000 to 3,000 sq ft of connected air, runs under 38 dB and is scheduled by app. A tall room connected to the spaces around it is precisely the shape that figure was written for.Is a small passive bottle really not enough in a room like that?

The short answer
Short answer: Read the published figure as what it is: up to 1000 cubic metres of one connected body of air, quoted on the page as about 2,000 to 3,000 sq ft at ordinary ceiling heights. SOSA Vaayu is Rs 11,999, under 38 dB, scheduled by app. How a very tall room changes that arithmetic is not published - ask.
The pick: A SOSA Vaayu at ₹11,999 for the tall room and everything genuinely open to it - with the height itself checked on WhatsApp before you buy.
Why: It is the one thing in the range that publishes a figure for air rather than for a surface, it runs under 38 dB in a room that carries sound, and it comes complete with four 100 ml fragrances.
In this guide
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
What actually suits a double-height living room that opens into the connected spaces around it?
Something measured in air. That sounds abstract and it is the practical heart of the question: a double-height room is not a bigger floor, it is a taller volume, and every small passive product in home fragrance is rated - when it is rated at all - for being near you. SOSA Vaayu at ₹11,999 is the one in the SOSA range that publishes a figure for the volume itself: up to 1000 m3, stated on the product page as about 2,000 to 3,000 sq ft. It is waterless cold-air diffusion - a dry, residue-free mist with no water and no heat - with a 400ml refillable tank, Bluetooth app control plus onboard buttons, run windows of 1, 4, 8 or 24 hours with day scheduling and adjustable intensity, operation under 38 dB, DC 12V / 1A at 5W, 165 x 80.5 x 215 mm and 0.9 kg, black or white, freestanding or wall and HVAC mounted, CE, RoHS and SGS marked, made in India, and it ships with four SOSA Hotel Collection fragrances of 100 ml each. Now the two caveats that make the number usable. It assumes one connected body of air, which a tall living room opening into dining and a gallery usually is, and a corridor of closed doors never is. And the square-footage equivalent assumes an ordinary ceiling; how a double-height room changes that conversion is not something SOSA publishes, so it belongs on WhatsApp at +91 96192 18531 rather than in a confident sentence here. Fragrance also only adds a scent - it does not remove, neutralise or purify one. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Ambition in a room like this is not a bigger object. It is the only product that publishes a figure for air, read strictly enough to admit where it stops.
The honest shape of the answer: Vaayu at ₹11,999, published for up to 1000 m3 - about 2,000 to 3,000 sq ft of connected air at ordinary ceiling heights - under 38 dB, four 100 ml fragrances in the box.

Volume against floor area, and what a tall room does to a published number
Three things decide this, and the first is a distinction most fragrance pages never draw because most fragrance products have no number to draw it with.
1
First
The published number is a volume, and that matters here more than anywhere
Vaayu publishes up to 1000 m3. Cubic metres, not square metres. The product page then gives a square-footage equivalent - about 2,000 to 3,000 sq ft - and that conversion only works by assuming a ceiling of the ordinary kind, because an area becomes a volume only once you multiply it by a height.
A double-height room is exactly the case where that assumption stops holding. The plan stays the same and the air above it does not; a room with two storeys of height over it holds a great deal more air than the same plan under a normal ceiling. So the sq ft figure printed on the page is not wrong, it is simply answering a question about a differently shaped room from yours.
Here is the part worth saying out loud rather than glossing: SOSA does not publish how a very tall room changes that arithmetic. The volume figure is published, the area equivalent is published, and the bridge between them for a two-storey space is not. Give the ceiling height and the rough plan to WhatsApp on +91 96192 18531 and get an answer from the people who have the data, rather than a conversion done on a blog.

Tip: Cubic metres is the real unit. Square feet is a translation that assumes a ceiling you do not have.

Second
Why a small passive product is the wrong shape of answer, not a cheap one
There is nothing second-rate about a reed diffuser from ₹749, or about the 130 ml bottles at ₹1,249 to ₹1,349, or a duo set from ₹1,498. They run about 6 to 10 weeks, they are passive, there is nothing to plug in or switch off, and they work whether or not anybody is in the building. In a study, a bedroom or a landing they are the correct answer and a machine would be absurd.
The mismatch in a tall room is geometric. A passive bottle evaporates into the air immediately around itself, and the air immediately around a console table is a small fraction of the air in a two-storey room. Put one on a plinth beneath eight metres of nothing and it is still doing its own honest job at its own honest scale - it has simply been asked to fill a volume it was never rated for.
So the argument is not that a cheap thing is unworthy of the room. It is that the room is defined by its air, and one product in the range is rated for air. The rest are rated, implicitly, for proximity.

Third
Quiet, scheduled, complete - and three things to ask before buying
A tall room carries sound, so the noise figure is not a footnote here. Operation is published at under 38 dB, and the machine is controlled by Bluetooth app or its own buttons, with run windows of 1, 4, 8 or 24 hours, chosen days, adjustable intensity, auto-stop and a key-lock. A gift that sits humming under a double-height ceiling would be a bad gift; a published figure is a better answer to that worry than a reassurance.
It is complete when it is opened. Four SOSA Hotel Collection fragrances of 100 ml each come in the box, in one of three published sets, all at ₹11,999. SOSA waterless nebuliser refills follow at ₹1,049 for 100 gm and ₹1,849 for 300 gm; the machine takes alcohol-free, water-free oil made for cold-air diffusion, and the water-based bottles on the site belong to the ultrasonic line.
Three things to ask rather than assume. How the ceiling height changes the coverage arithmetic, which is not published. How long a 400ml fill actually lasts, which the page states two different ways - about 75 days in its specification data and 90 or more in its body copy - and which depends on intensity and scheduled hours regardless. And where the unit is meant to sit, since wall and HVAC mounting is published as an option while fixings are not SOSA's to advise on. There is no published installation service, no warranty period and no running-cost figure either.

Tip: Give them the ceiling height. It is the one dimension the published conversion cannot see.
Read the number strictly, not generously
About 2,000 to 3,000 sq ft - of air that is actually connected
Vaayu publishes a coverage figure, which almost nothing in home fragrance does: up to 1000 m3, stated as about 2,000 to 3,000 sq ft. The caveat matters more than the number. A rating assumes one connected body of air. A ground floor that runs living into dining into a stairwell is one volume and is exactly what the figure describes. A bungalow of the same total area with six closed doors is not one volume, it is six rooms, and the figure does not transfer. Work out how much of the house is genuinely open before you work out anything else - and note that no guidance is published on what a second unit adds.
See SOSA Vaayu ₹11,999 →
Work it out in this order
Four steps, and the tape measure matters more than the price list
- Note the ceiling height of the tall room. It is the number nobody has yet.
- Walk from it and mark where a door closes. That edge is the volume's edge.
- Treat 1000 m3 as the real figure and the sq ft line as a translation.
- Send the height and the plan to WhatsApp before you settle on anything.
The SOSA principle
Every layer in a room like this was specified against a number - a span, a lux level, a load. Scent is the only layer that arrived with no number attached to it, which is why a product that publishes one is worth more here than a product that looks expensive.
And it is also why the honest thing to do with that number is to state where it stops, because a figure quoted past its own assumptions is worth less than no figure at all.
Which set, and what a room with that much air above it asks for
Three published four-scent sets exist and all three cost ₹11,999, so this is a question of taste rather than budget. They pair Ritz-Carlton with Westin, St. Regis and 1 Hotels inspirations; Westin with Shangri-La, Four Seasons and Ritz-Carlton; and St. Regis with W Hotels, 1 Hotels and Four Seasons. To be plain about what they are: SOSA's own hotel-inspired interpretations, composed by SOSA, and SOSA is independent and not affiliated with any hotel brand. In a double-height room there is an argument for the quieter end of the register rather than the most declarative one, because a big volume is a big canvas and a strongly stated scent has nowhere to hide in it. Four 100 ml bottles let the room itself decide, which is a better method than a shop counter, and the waterless nebuliser oils at ₹1,049 for 100 gm keep a change of mind cheap.
The SOSA gift edit
Four answers to a tall connected room, and the limit of each
| The option | Who it suits, and where it fails |
|---|---|
| SOSA Vaayu · ₹11,999 | The only one here rated for air: up to 1000 m3, published as about 2,000 to 3,000 sq ft of connected volume at ordinary ceiling heights, under 38 dB, 1, 4, 8 or 24-hour windows, four 100 ml fragrances in the box. Its limit is that the effect of an unusual ceiling height is not published, so ask. |
| A 130 ml reed diffuser · ₹1,249 to ₹1,349 | Passive, about 6 to 10 weeks, nothing to plug in or operate, and genuinely right for a study, a landing or a bedroom off the main space. Its limit in a two-storey room is geometry: it scents the air immediately around itself, and that air is a small share of the total. |
| A duo gift set · ₹1,498 to ₹2,598 | Two bottles in one box, three published pairings, both bottles the same size, none composed to order. It looks like an occasion and it suits two smaller connected rooms rather than the tall one. Its limit is the same as the single bottle's, doubled but not scaled. |
| SOSA Meenar · ₹38,500 | Published for 12,000 to 18,000 sq ft. If the reasoning is that a tall room deserves the biggest machine, this is where that reasoning lands, and it is the wrong building - Meenar answers a hotel lobby or a corporate floor, not a house, however high its ceiling. |
The two details that matter in a finished house
Under 38 dB, and it runs only when you tell it to
Two published details decide whether this belongs in a house somebody spent years on. It runs under 38 dB, which is the answer to the reasonable worry about a machine humming in a double-height living room. And it is scheduled: Bluetooth app plus onboard buttons, run windows of 1, 4, 8 or 24 hours, chosen days and adjustable intensity, with auto-stop and a key-lock. That is what makes it workable in a house occupied for part of the year, or a room used only when people come over. It is 165 x 80.5 x 215 mm and 0.9 kg, black or white, freestanding or wall and HVAC mounted, and it ships with four 100 ml fragrances - so it is complete on the day it arrives.
See the nebuliser refills from ₹1,049 →
It is worth knowing what else exists so that nobody reaches upward by reflex. SOSA Meenar at ₹38,500 is published for 12,000 to 18,000 sq ft and is a commercial machine; between it and Vaayu there is nothing in the catalogue, and a house almost never wants it. The ultrasonic machines - Boond at ₹899, Sukoon at ₹1,899, Megh at ₹5,999 - are water-based, sized for a single room, and want water and regular refilling, which is a recurring ask of somebody who did not choose them. SOSA Safar at ₹3,999 is cordless and portable: it travels with a person rather than scenting a property, and it is imported rather than made in India. Each of those is a good answer to a question that is not this one.
₹11,999. Up to 1000 m3, stated as about 2,000 to 3,000 sq ft of connected volume. A 400ml tank, Bluetooth app plus onboard buttons, 1h/4h/8h/24h run windows and adjustable intensity. Under 38 dB.
₹11,999
165 x 80.5 x 215 mm and 0.9 kg, in black or white, freestanding on a surface or wall and HVAC mounted. DC 12V / 1A at 5W, with auto-stop and a key-lock, and CE, RoHS and SGS marks.
0.9 kg · under 38 dB
Every Vaayu ships with four SOSA Hotel Collection fragrances, 100 ml each, in one of three published four-scent sets. So it is complete on arrival, which matters more for a gift than it sounds.
four x 100 ml included
One message, one honest recommendation
Tell SOSA who it is for, roughly how big the room is, whether their home is already scented and what you want to spend - and you will be told which size and which scent, including the times the honest answer is the 50ml rather than the 130ml.
A double-height room is not a larger floor. It is a taller column of air, and air is the one thing in that house nobody was ever asked to specify.
— 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.

Start from the architecture, not from the budget
| Product | What it is | What it is for | Price |
|---|---|---|---|
| SOSA Vaayu | Waterless cold-air scent machine | Up to 1000 m3, stated as about 2,000 to 3,000 sq ft of connected volume - a 400ml tank, Bluetooth app and onboard buttons, 1h/4h/8h/24h scheduling, adjustable intensity, under 38 dB | ₹11,999 |
| SOSA Meenar | The commercial-scale machine | Published for 12,000 to 18,000 sq ft - a hotel, showroom or corporate answer rather than a home one, and rarely the right gift | ₹38,500 |
| SOSA reed diffuser duo sets | Two bottles, two rooms | ₹1,498 to ₹1,598 in 50ml x 2 and ₹2,498 to ₹2,598 in 130ml x 2, about 6 to 10 weeks - passive, and running whether or not anybody is in the house | from ₹1,498 |
| SOSA reed diffusers | One room at a time | ₹749 to ₹849 in 50ml and ₹1,249 to ₹1,349 in 130ml - nothing to schedule, nothing to plug in, and no control over when it runs | from ₹749 |
| SOSA ultrasonic machines | Water-based, single room | Boond ₹899, Sukoon ₹1,899 and Megh ₹5,999 - they need water, a socket and regular refilling, and they suit one room rather than a connected floor | from ₹899 |
| SOSA Safar | Portable, cordless, 6.9 cm | ₹3,999 - it goes with a person to a car, a bag or a hotel room. It does not scent a property, and it is imported rather than made in India | ₹3,999 |
| SOSA attars | Alcohol-free roll-on oil | Worn on the body rather than placed in a room - the right answer when the gift is about the person and not the house | from ₹379 |
A coverage rating assumes one connected body of air. Vaayu's figure describes an open-plan volume - a living-dining floor, a duplex's main level, a double-height hall. A house with every internal door shut is not one volume, and the figure does not transfer to it. Every Vaayu ships with four SOSA Hotel Collection fragrances, 100 ml each, and its country of origin is India. Fragrance adds a scent to a space; it does not remove, neutralise or purify one, and the dry residue-free mist is a statement about residue rather than about air quality. SOSA blends described as hotel-inspired are SOSA's own interpretations and SOSA is independent and not affiliated with any hotel brand. Prices above are published retail prices; bulk orders are welcome and quantities are settled on WhatsApp at +91 96192 18531. SOSA is an Indian fragrance house based in Pune. A portion of every order supports girl-child education through Nanhi Kali.
The honest spec sheet
What the Vaayu page publishes, and what it does not
Everything below is on the live product page. Anything not on this list is not something a page like this should state.
- Coverage - up to 1000 m3, published as about 2,000 to 3,000 sq ft. A rating assumes one connected body of air, so it describes an open-plan floor rather than a house of closed rooms.
- The machine - waterless cold-air diffusion, dry and residue-free, no water and no heat. 165 x 80.5 x 215 mm, 0.9 kg, black or white, freestanding or wall and HVAC mounted. DC 12V / 1A, 5W. Under 38 dB. Auto-stop and key-lock. CE, RoHS and SGS. Country of origin India.
- Control - a 400ml refillable tank, Bluetooth app plus onboard buttons, run windows of 1h, 4h, 8h or 24h, day scheduling and adjustable intensity. This is what makes it workable in a house that is empty for stretches, or a room used only at weekends.
- In the box - every Vaayu ships with four SOSA Hotel Collection fragrances, 100 ml each, in one of three published four-scent sets, all at ₹11,999. SOSA blends described as hotel-inspired are SOSA's own interpretations and SOSA is independent and not affiliated with any hotel brand.
- The fragrance - alcohol-free, water-free oils formulated for cold-air diffusion. SOSA waterless nebuliser refills are ₹1,049 for 100 gm and ₹1,849 for 300 gm and are published for Vaayu and Safar. The water-based ultrasonic bottles belong to a different kind of machine.
- Not published, and therefore never stated here: how long a 400ml fill lasts as a single figure - the page says about 75 days in one place and 90 or more in another; what a second unit adds; any warranty period, service interval or filter; any installation service; any app name, phone compatibility or Bluetooth range; and any running or electricity cost. Those go to WhatsApp +91 96192 18531.
Not sure whether the house needs a machine or a bottle? Tell SOSA on WhatsApp at +91 96192 18531 four things: roughly how much of the ground floor is one connected open volume, whether the internal doors stay open or shut, how often the house is actually occupied, and what you want to spend. You will get one straight answer rather than a catalogue - including the times the honest answer is a reed diffuser from ₹749 or a duo set from ₹1,498 rather than a machine. What is not on this page, because SOSA does not publish it: what a second unit adds, any warranty period, any installation service, any running or electricity cost, and any app or Bluetooth compatibility detail. One thing to check before you buy: the Vaayu page states the life of a 400ml fill two different ways - about 75 days in one place and 90 or more in another - and it depends on intensity and scheduled hours in any case, so ask rather than plan around a number. Every Vaayu ships with four SOSA Hotel Collection fragrances, 100 ml each; SOSA waterless nebuliser refills are ₹1,049 for 100 gm and ₹1,849 for 300 gm. Bulk orders are welcome and custom label or logo on product is available; quantities and anything commercial are settled on WhatsApp rather than priced on a page. Bespoke composition, a fragrance composed for you by Sonal, is a real SOSA service and is also discussed there. Where SOSA is: an Indian fragrance house based in Pune, sending orders across India, with no shop, stockist, counter or warehouse in any other city.

A note from Sonal
The messages I find hardest to answer are the ones that begin with an apology. They have just finished building the house. I don't want to sound cheap, but I also can't buy them anything that matters at that scale. And underneath it is a real anxiety: that after years of drawings and delays and site visits, whatever you turn up with will look like a token.
What I would say is that the anxiety is aimed at the wrong thing. You are not competing with the house. Nobody is. The people who built it spent two years choosing between four shades of the same stone, and there is no object you can hand over that will register on that scale. Trying is how people end up buying a vase that gets moved to a spare room.
The reason I keep coming back to scent for these particular houses is unromantic. It is the last layer, and it is the only one nobody planned. An architect resolves the volume, a designer resolves the surfaces, a lighting consultant resolves the evening, and then everybody stops - because scent is not on anybody's drawing. So it is one of the few things left that adds to a finished house without arguing with a single decision already made in it.
The part I would be careful about is the number. Vaayu publishes a coverage figure, which almost nothing in home fragrance does, and I would rather you read it strictly than generously. About 2,000 to 3,000 sq ft, of air that is actually connected. A ground floor that opens living into dining into a stairwell is that. A bungalow with six closed doors is not that, whatever its total square footage says on paper, and a page that blurs the two is doing you no favours.
Frequently asked questions
Does the coverage figure still apply in a double-height room?
Partly, and the honest part is the volume. SOSA publishes up to 1000 cubic metres, and separately quotes that as approximately 2,000 to 3,000 square feet - a conversion that assumes a ceiling of the ordinary kind. A double-height room holds far more air over the same plan, and SOSA does not publish how that changes the arithmetic. Send the ceiling height to WhatsApp at +91 96192 18531 and ask.
Will a small passive diffuser work in a two-storey living room?
It will do what it does, which is scent the air immediately around itself. In a tall room that is a small share of the total air, so a reed diffuser is a good gift for a study, a landing or a bedroom and an awkward one for the main volume. SOSA reed diffusers are Rs 749 to Rs 849 in 50 ml and Rs 1,249 to Rs 1,349 in 130 ml, running about 6 to 10 weeks.
Would a larger machine be the more ambitious choice?
Not for a house. SOSA Meenar at Rs 38,500 is published for 12,000 to 18,000 square feet, which is a hotel lobby, a showroom or a corporate floor. In a home, even one with a two-storey living room, it is not the ambitious option but the wrong one. The catalogue holds nothing between Meenar and Vaayu at Rs 11,999.
Is it audible in a room that carries sound?
SOSA publishes operation at under 38 dB, and it runs only when it is scheduled to. Control is by Bluetooth app or the buttons on the unit, with run windows of 1, 4, 8 or 24 hours, chosen days, adjustable intensity, auto-stop and a key-lock. A tall room does carry sound, which is why a published figure is more use here than a reassuring adjective.
How long does one tank last, and what else is not published?
The 400 ml tank is refillable, but the product page gives its life two different ways - about 75 days in its specification data and 90 or more days in its body copy - and either way it depends on intensity and scheduled hours. Also not published: how ceiling height changes coverage, what a second unit would add, no warranty period, no service interval, no installation service and no running-cost figure. Ask on WhatsApp at +91 96192 18531.
Take the next step
Measure the height before you choose the gift
Vaayu at ₹11,999 is rated for up to 1000 m3 of one connected body of air, quoted as about 2,000 to 3,000 sq ft where ceilings are ordinary - under 38 dB, scheduled by app, four 100 ml fragrances in the box. How a two-storey ceiling changes that is not published, so send the height and the plan to SOSA and ask. Reed diffusers from ₹749 remain right for the smaller rooms off it.
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-buying reasoning applies to any brand.Specifications verified from the live SOSA product pages, September 2026: SOSA Vaayu ₹11,999 is a waterless cold-air scent diffuser producing a dry, residue-free mist with no water and no heat.

Its country of origin is India. Every Vaayu ships with four SOSA Hotel Collection fragrances of 100 ml each, in one of three published four-scent sets, all at the same price. SOSA Meenar ₹38,500 is published for 12,000 to 18,000 sq ft. The ultrasonic machines Boond ₹899, Sukoon ₹1,899 and Megh ₹5,999 are water-based and suit a single room or small area. SOSA reed diffusers are ₹749 to ₹849 in 50 ml and ₹1,249 to ₹1,349 in 130 ml, lasting approximately 6 to 10 weeks, with three duo combo sets at ₹1,498, ₹1,548 and ₹1,598 in two 50 ml bottles and ₹2,498, ₹2,548 and ₹2,598 in two 130 ml bottles; those three pairings are the entire set range and none is composed to order. SOSA Safar ₹3,999, or ₹4,499 for the hotel-inspired trios, is a waterless cordless portable diffuser of approximately 6.9 cm with a 2000 mAh Type-C battery giving up to 10 hours continuous or 30 hours intermittent per charge, three speeds and a 1, 2 or 3-hour auto shut-off; its country of origin is China. SOSA attars are ₹379 to ₹399 in 3 ml, rising to ₹1,149 to ₹1,199 in 12 ml. SOSA waterless nebuliser refills for Vaayu and Safar are ₹1,049 for 100 gm and ₹1,849 for 300 gm. About the coverage figure: a rating assumes one connected body of air. The published figure describes an open-plan volume such as a living-dining floor, a duplex's main level or a double-height hall, and does not describe a property whose rooms are separated by closed doors, whatever its total floor area. No guidance is published on what a second unit adds. About tank life: the Vaayu product page states the life of one 400 ml fill in two different ways - approximately 75 days in its specification and FAQ data, and 90 or more days in its body copy - and in either case it depends on the intensity setting and the scheduled hours, so no single figure is stated on this page. What is not published, and is therefore not stated here: any warranty period, service interval or filter; any installation service; any app name, phone compatibility or Bluetooth range; any running or electricity cost; and any multi-unit coverage. Limits of this guide: fragrance adds a scent to a space. It does not remove, neutralise, mask or purify odour, it does not clean the air, and no SOSA product makes any health, antibacterial or air-purifying claim; a dry residue-free mist is a statement about residue and not about air quality. No claim is made anywhere on this page about mood, stress, calm, sleep or wellbeing, nor about how any recipient or guest will feel, nor about what a gift does for any business result. No page here characterises any recipient's wealth or describes people who own particular kinds of property; where a property value appears it is the figure the reader themselves supplied as context. SOSA blends described as hotel-inspired are SOSA's own interpretations and SOSA is independent and not affiliated with any hotel brand. 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.
