★ SOSA Safar — Verified Owner Reviews
Readers ask this question expecting a single number back, and the honest reply is that a car fragrance has three cost lines, that two of them are printed on the product page, and that nobody publishes the third

Founder Diaries · SUV Fragrance · Choosing a Format
Can SOSA tell me the cost per millilitre of each format? Not across the two systems, and the reason is a unit mismatch rather than reluctance. The car perfumes are sold by volume in millilitres and the waterless refills are sold by weight in grams, and Safar ships with a 20ml bottle. There is no published conversion between the two, so any cost-per-millilitre table that compares them has quietly invented one. Within a single system the comparison is clean.
What should I compare instead of purchase price? Compare the two published lines side by side, then establish the third for yourself before you buy a second time. Purchase price tells you the cost of starting. Refill price tells you the cost of continuing, and on the hanging format it is lower than restarting. Consumption tells you how often line two recurs, which is the figure that decides everything and the one you have to measure.

Facts verified 3 October 2026 against the live SOSA product pages: SOSA car perfume is sold as one 12ml product in two formats at the SAME price, listed on the product page as "Spray (Strong scent-throw)" or "Hanging (Mild scent-throw)", with a "50 ML Car Perfume Spray" at ₹1,499. The nine scents are Jasmine ₹449, Lavender ₹479, Sandalwood ₹479, Icy Mint ₹489, Lemon ₹499, Vetiver khus ₹509, Sea Breeze ₹509, Oud ₹509 and Mysore Orange Blossom ₹549, the last of which is spray only. Car Hanging Freshener Refills are 15ml at ₹399 to ₹449 in eight scents - a larger bottle than the 12ml unit they refill. The SOSA Safar waterless car and travel diffuser is ₹3,999 for the SOSA scent trios and ₹4,499 for the hotel-inspired trios, with three speed settings, an auto shut-off timer at one, two or three hours, up to ten hours continuous or thirty hours intermittent per charge, a 2000 mAh battery, Type-C charging, a body of about 9 cm that fits a cup-holder, and a 20ml bottle in the box; it diffuses pure undiluted oil cold, with no water and no heat, and the product page states "Aroma only - does not humidify", which is not a claim that it dries a cabin or corrects damp. SOSA publishes NO coverage figure for Safar - no square feet, no cubic metres and no seat count - so no page here sizes it to a vehicle. Waterless Nebuliser Refills are shared with the SOSA Vaayu at ₹1,049 per 100 gm and ₹1,849 per 300 gm for the SOSA scents, and ₹1,099 and ₹1,899 for the hotel-inspired scents; that range contains no oud and no lavender, while the 12ml range contains both. The car perfumes are sold by volume and the waterless refills by weight, so a cost per millilitre across the two systems is not available from the published figures and none is given here. SOSA publishes no duration figure for a 12ml unit, a 20ml Safar bottle or any speed setting. No SOSA product removes an odour at its source: food, damp and smoke in a cabin are cleaning and ventilation problems, and fragrance sits on top of whatever is already there. SOSA makes no claim about mood, alertness, concentration, wellbeing or driving, and no claim about air quality or purification. After-sales terms, bulk arrangements and delivery commitments are confirmed with SOSA directly; free shipping above ₹499 is the only logistics fact stated. The hotel-inspired scent names are SOSA’s own interpretations and catalogue variant names; SOSA is independent and not affiliated with any hotel or brand named for reference. Prices and availability are subject to change - see the live product pages.
You are right that purchase price is the wrong comparison, and you may be surprised by how wrong. A car fragrance has three cost lines, and only two of them are published. Line one is what you pay to start: ₹449 to ₹549 for a 12ml car perfume, ₹1,499 for the larger bottle, ₹3,999 for a SOSA Safar or ₹4,499 for the hotel-inspired trios. Line two is what you pay to keep going: ₹399 to ₹449 for a 15ml hanging refill, ₹1,049 or ₹1,849 for a waterless refill. Line three is how fast each one is consumed - and SOSA publishes no figure for that at all. So grade the lines rather than averaging them.

How do I compare the true cost of the three car fragrance formats? Grade three lines separately. Purchase price is verified: 12ml car perfume ₹449 to ₹549 in either form of release, a “50 ML Car Perfume Spray” at ₹1,499, SOSA Safar ₹3,999 or ₹4,499. Refill price is verified: 15ml hanging refills ₹399 to ₹449, waterless refills ₹1,049 per 100 gm and ₹1,849 per 300 gm, ₹1,099 and ₹1,899 for the hotel-inspired scents.

The short answer
Short answer: Compare three lines and grade each one. Line one, purchase price, is verified - 12ml car perfume from jasmine ₹449 to Mysore Orange Blossom ₹549, the same price in either form of release, a “50 ML Car Perfume Spray” at ₹1,499, a three-spray discovery set ₹699 to ₹899, and SOSA Safar at ₹3,999 or ₹4,499 for the hotel-inspired trios. Line two, refill price, is also verified - 15ml hanging refills ₹399 to ₹449 across eight scents, waterless refills ₹1,049 per 100 gm and ₹1,849 per 300 gm. Line three, consumption rate, is published nowhere, for any format or any speed setting, which means every cost-per-use figure you have read somewhere was built on an assumption its author did not show you. Two solid lines and one measured by you beats three lines where one is borrowed.
The pick: start on the published lines you can check. A 12ml jasmine at ₹449 or lemon at ₹499 is the cheapest entry to line one, and the 15ml hanging refills at ₹399 to ₹449 are line two for the passive format - a larger bottle than the 12ml unit they refill. SOSA Safar at ₹3,999 and its waterless refills at ₹1,049 per 100 gm are the other system entirely, with its own line two.
Next step: buy one format, mark the bottle, write the date beside the mark, and photograph the level once a week for a month. That gives you line three for your own vehicle, which is the only place it exists. Then read the page that turns those three lines into a cost per occupied driving hour and the verified arithmetic of refilling against rebuying. Or send SOSA your driving hours and parking and we will tell you which line is going to dominate your own total.

Two of the three lines can be read off a product page in a minute. The third decides the total and has to be established in your own vehicle, because nobody publishes it.

Straight answer
I keep comparing ₹449 against ₹3,999 and getting nowhere. How should I actually compare the true cost of these three formats?
Stop looking for one number and start grading three lines, because they are not equally knowable and pretending they are is how readers get misled. Line one is purchase price, and it is fully verified. A SOSA 12ml car perfume runs from jasmine at ₹449 through lavender and sandalwood at ₹479, icy mint ₹489, lemon ₹499, vetiver khus, sea breeze and oud at ₹509, to Mysore Orange Blossom at ₹549 - and critically, the price is the same whether you choose “Spray (Strong scent-throw)” or “Hanging (Mild scent-throw)” on that page, so line one cannot separate those two formats at all. A “50 ML Car Perfume Spray” is ₹1,499. A three-spray discovery set is ₹699 to ₹899, with a pack of nine at ₹2,999. A SOSA Safar is ₹3,999 for the SOSA scent trios and ₹4,499 for the hotel-inspired ones. Every figure in that paragraph is on a live product page and you can check all of it before you finish your coffee. Line two is refill price, and it is also fully verified - and it is the line most readers never look at. A 15ml hanging refill is ₹399 for lemon or jasmine, ₹429 for sandalwood, lavender or icy mint, and ₹449 for sea breeze, vetiver or oud. A waterless refill for Safar is ₹1,049 per 100 gm or ₹1,849 per 300 gm in SOSA's own scents, and ₹1,099 or ₹1,899 in the hotel-inspired range. Line two is where the two systems genuinely diverge, and where line one was actively deceiving you. The 12ml format is cheap to start and cheap to continue. The device is dear to start and its refills are the dearest single purchase in the whole range. Line three is consumption rate, and it does not exist. Not as a secret, not as an estimate, not as a figure I am withholding. SOSA publishes no duration for a 12ml unit in either form of release, none for the 20ml bottle that ships with Safar, and none for what any of the three speed settings draws while running. So the question that would finish the sum - how often does line two recur? - has no published answer, and any page that gives you one has built it from usage assumptions it did not show you. There is one more honest limit and I would rather state it than fudge it. The car perfumes are sold by volume, in millilitres; the waterless refills are sold by weight, in grams. SOSA publishes no conversion between them, so a true cost per millilitre spanning both systems is not available from the published figures. Inside one system it is clean: 15ml for ₹399 against 12ml for ₹449 is a real comparison and it goes the way you would not expect. So the method is three steps rather than a formula. Read line one off the page for your shortlist. Read line two, which most people skip and which is where the long-run difference lives. Then buy one format and spend a month establishing line three for your own vehicle: a pen mark at the liquid level, the date beside it, a photograph once a week. Two published lines and one you measured beats three lines where somebody else guessed the important one.
Grade the lines. Purchase price is verified - 12ml ₹449 to ₹549, a 50 ML Car Perfume Spray ₹1,499, Safar ₹3,999 or ₹4,499. Refill price is verified - 15ml hanging refills ₹399 to ₹449, waterless refills ₹1,049 per 100 gm and ₹1,849 per 300 gm. Consumption rate is published nowhere, so measure it yourself with a pen mark and a date. Flip: if you will only ever buy once and never refill, line one really is the whole cost.
The cheapest honest way to start measuring is one 12ml unit: SOSA Jasmine car perfume at ₹449, alcohol-free, the same price in either form of release. Mark the level, write the date, and you own line three for your own vehicle inside a month.

The three lines, graded
Read the two cards below as two cost structures rather than two price points. One is cheap at the start and cheap to continue, with line two lower than line one. The other is expensive once and then has the dearest refill in the range. Which of those is better value depends entirely on the line nobody publishes.
The structure where both published lines are low
SOSA Jasmine Car Perfume
Line one is ₹449 to ₹549 for 12ml, identical in either form of release, so this format is the cheapest entry in the range. Line two is lower still: a 15ml hanging refill is ₹399 to ₹449, which is less money for more oil than the unit it refills. What you cannot read off the page is how often line two comes round, because no duration figure is published for a 12ml unit in either form. For a reader who wants to keep total spend predictable and small, this is the structure that is hardest to get badly wrong.
₹449 for 12ml · jasmine, either form of release
The structure that is dear once and then has the dearest refill
SOSA Safar Waterless Car Perfume Diffuser
Line one is ₹3,999, or ₹4,499 for the hotel-inspired trios, and it buys published control: three speed settings, an auto shut-off timer at one, two or three hours, and up to ten hours continuous or thirty intermittent per charge. Line two is ₹1,049 per 100 gm or ₹1,849 per 300 gm, ₹1,099 and ₹1,899 for the hotel-inspired scents. Both lines are higher than the 12ml system on every reading, so this only becomes the better total if your occupied hours are high enough to use what the control does. No coverage figure is published for it, so nothing here sizes it to a cabin.
₹3,999 · or ₹4,499 for the hotel-inspired trios
Why purchase price misleads so reliably
Five reasons, in the order they cost readers money. The first is specific to SOSA and catches almost everybody.
1
Line one cannot separate the two cheap formats
Spray and hanging are the same price on every scent, so purchase price is silent on the choice most readers are actually making
The first thing purchase price does wrong is answer a question nobody asked. On a SOSA product page, “Spray (Strong scent-throw)” and “Hanging (Mild scent-throw)” are two forms of release of one 12ml composition at one price. Jasmine is ₹449 either way. Oud is ₹509 either way. So if you line the formats up by price you will see two entries sitting on top of each other and conclude they are interchangeable on cost - which is true of line one and completely false of the total, because a passive unit releases continuously whether anyone is aboard and a spray releases only when pressed. That difference lands in line three, which is the line without a published figure. The format comparison that follows from that is where this belongs in full.
Rule: if two options have the same purchase price, purchase price is not a comparison. The difference has moved into consumption.
2
Line two is the line that compounds
A purchase happens once; a refill happens again and again, so a small difference there outweighs a large difference at the start
The second reason is arithmetic rather than opinion. Line one is paid once. Line two is paid however many times you keep the format, so its weight in the total grows while line one's weight shrinks. That is why the gap between ₹399 and ₹1,049 matters more over two years than the gap between ₹449 and ₹3,999 - and it is also why I will not pretend to tell you when the crossover happens, because the crossover is a function of how often each refill recurs, and that figure is not published for either system. The page that puts the two refill prices properly side by side states the unit mismatch rather than converting around it.
15ml hanging refills, ₹399 to ₹449 - line two for the passive format, and a larger bottle than the 12ml unit it refills on all eight scents.
See the 15ml refills →
3
The missing line is the one that decides the total
Consumption rate is not published for any format, and it is the multiplier on line two
The third reason is the honest centre of this page. Total cost is roughly line one plus line two multiplied by how often line two recurs, and that multiplier is exactly what SOSA does not publish: no duration for a 12ml unit in either form of release, nothing for the 20ml bottle supplied with Safar, and nothing for what a given speed setting draws per hour of running. I am not going to invent it. Nor should you accept it from anywhere else without asking what week, what climate and what parking the figure assumed. Heat accelerates evaporation and takes the lightest materials first, so the same unit in an uncovered bay through an Indian summer is not the same unit in a basement in December. What a published day-count is actually based on takes that apart properly.
Procedure: mark the liquid level with a pen, write the date beside the mark, photograph it weekly for a month. That is your multiplier, and it is the only one that applies to you.
4
Millilitres and grams are not the same instrument
The two systems are sold in different units, so no honest cost per millilitre spans both
The fourth reason is why so many comparison tables are quietly fiction. SOSA car perfumes are sold by volume - 12ml, 15ml for the refill, 20ml for the bottle in the Safar box, 50ml for the larger spray. The waterless refills are sold by weight - 100 gm and 300 gm. There is no published conversion between those, and the correct conversion is not one you can guess, because it depends on the density of the specific oil. So when you see a table that puts a per-millilitre figure for a car spray next to a per-millilitre figure for a waterless refill, somebody has converted grams to millilitres on an assumption they did not state. Compare within a system, where the units agree, and compare the two systems on what is genuinely comparable: line one, line two, and how often each is consumed in your own week.
Rule: volume against weight is not a comparison. Within one system the units agree and the arithmetic is real.
5
There is a fourth line, small but real
Free shipping above ₹499 is the only logistics fact SOSA publishes, and the cheapest units sit under it
The fifth reason is minor and I include it because it is verified and almost always left out. Free shipping applies above ₹499, which is the only logistics fact on these pages. A single jasmine at ₹449, a sandalwood at ₹479 or an icy mint at ₹489 does not reach that threshold alone; a vetiver khus or oud at ₹509, a discovery trio from ₹699 or a Safar at ₹3,999 clears it. I will not tell you what shipping costs below the line, because SOSA publishes no figure for it and I am not inventing one. I am telling you the threshold exists, because on the cheapest line-one purchase in the range it is a real part of the total.
Note: after-sales terms, bulk arrangements and delivery commitments are confirmed with SOSA directly. Free shipping above ₹499 is the only logistics figure published.
The SOSA principle
A car fragrance has three cost lines. Two are printed on the product page and one does not exist anywhere, and the one that does not exist is the one that decides the total.
That is not a weakness in the comparison - it is the comparison. Grade the lines honestly, then spend a month measuring the third in your own vehicle rather than borrowing somebody else's assumption.
The one change that reverses this answer
This page has argued that purchase price is the wrong comparison. There is a reader for whom that is wrong, and the honest thing is to name them rather than pretend the method is universal.
The honest reversal
When the three-line method collapses back to a single number, and when it does not
| The reader | What the true cost actually is for them, and why |
|---|---|
|
Buying one 12ml unit, once, and never refilling it
|
Line one really is the whole cost, and the method on this page is overkill. If you want fragrance in the vehicle for a season, will use one bottle and will not replace it, then ₹449 to ₹549 is the complete and final figure and nothing in this page improves on it. Grading three lines is only worth the effort when line two is going to recur. View ₹449 → |
|
Settled on one scent and one format for the long run
|
Line two dominates, and it is the line you should be shopping on. Once a format is chosen and a scent is settled, line one is history and the only money still moving is the refill. That makes the 15ml refill at ₹399 to ₹449 the figure that decides your total - and it is lower than the unit it refills, which is the single most useful piece of arithmetic in this family. View ₹399 → |
|
Weighing a device against a bottle for the first time
|
All three lines matter and the missing one is decisive, so buy the cheap format first. You cannot settle ₹3,999 against ₹449 without knowing how often each is consumed, and that is the unpublished line. Spend a month establishing it on a 12ml unit, which costs little and teaches you your own consumption, and then decide with a real multiplier instead of a borrowed one. View ₹3,999 → |
|
What this page is not claiming
|
That any format is cheaper per use than any other - that would require the consumption figure nobody publishes. It is also not giving a cost per millilitre across the two systems, because volume and weight do not convert without an assumption. And no claim is made here about air quality, odour removal, mood, alertness, wellbeing or driving: a car perfume is a fragrance sitting on top of whatever is already in the cabin, and it removes nothing. |
Two neighbours of this page are worth reading before you spend anything. Whether the cheapest format is actually the best value for a heavy user takes the crossover question seriously and refuses to invent the crossover. Cost per month rather than purchase price changes the denominator and surfaces something this page only touched: a passive unit's monthly cost is incurred whether you drive or not, where a spray's is not. If you want the full five-variable version with every line in one place, that is the family pillar.
Two published lines, one you measure in a month
Jasmine ₹449, lemon ₹499 or oud ₹509 for line one; 15ml refills ₹399 to ₹449 for line two. Send us your driving hours and your parking and we will tell you which of the three lines is going to dominate your own total, including when the answer is that line one is all you need.
I will give you every price on the page and I will not give you a cost per use, because the figure that would complete that sum is not published and I am not going to invent it for the sake of a tidier table.

How to establish line three yourself
All of this is free, takes a month of noticing rather than a month of effort, and produces the only consumption figure that applies to your vehicle rather than to somebody's assumption.
The method, in order
Four steps that turn two published lines and one gap into a total you can trust
| Step | What to do | Why it matters | Where it applies |
|---|---|---|---|
| SOSA Jasmine Car Perfume | Read line one off the page for your shortlist | Purchase price is published and takes a minute to verify. Note that it cannot separate the two forms of release, because they are the same price on every scent, so if your shortlist is spray against hanging, line one has already told you everything it can | ₹449 · 12ml View → |
| SOSA Car Hanging Freshener Refills | Read line two before you buy, not after | The refill price is the line that recurs and therefore the line that compounds. On the passive format it is ₹399 to ₹449 for 15ml against ₹449 to ₹509 for the 12ml unit, so continuing costs less than restarting - a figure that changes which format you should want to stay with | ₹399 · 15ml refill View → |
| SOSA Waterless Nebuliser Refills | Keep the two systems in their own units | ₹1,049 per 100 gm and ₹1,849 per 300 gm are the waterless figures, and grams are not millilitres. Compare within a system where the units agree, and compare across systems on line one, line two and frequency rather than on a converted per-unit figure | ₹1,049 · 100 gm View → |
| SOSA Safar Waterless Car Perfume Diffuser | Mark, date, photograph, and only then compare totals | A pen line at the liquid level, the date beside it and a weekly photograph gives you the multiplier nobody publishes. Do it on the cheap format first. A month of that is worth more than every cost-per-use table you will read, because it is measured in your parking and your climate | ₹3,999 · Safar View → |
Every 12ml car perfume here is alcohol-free and sold in two forms of release at the same price on the same page - “Spray (Strong scent-throw)” and “Hanging (Mild scent-throw)” - with a “50 ML Car Perfume Spray” at ₹1,499 alongside them. Line one and line two are both published; line three is published nowhere and this page does not fill the gap with a guess. SOSA publishes no coverage figure for Safar either, so nothing here sizes it to a cabin. A car perfume is a fragrance and nothing more: it does not mask the smell of a damp mat, a spill under a seat or an overdue cabin filter, which are cleaning and ventilation jobs, and SOSA makes no claim about air quality, odour removal, mood, alertness, concentration, wellbeing or driving. Tell us your driving hours and your parking and we will answer plainly, including when the honest answer is the cheapest bottle on the page.
What to buy, and what not to
For a reader at the start of this comparison, buy one 12ml unit and nothing else yet. Jasmine at ₹449 is the cheapest line one in the range. Lemon at ₹499 is the cheapest that also clears the ₹499 shipping threshold on its own. Oud at ₹509 is the most assertive. Then look at the 15ml refills at ₹399 to ₹449 before you decide which format you want to be living with, because that is line two and it runs the opposite way to what most readers expect. What not to buy yet: a ₹3,999 device on the strength of a cost-per-use figure you read somewhere, or a “50 ML Car Perfume Spray” at ₹1,499 before you know the scent. The ₹699 to ₹899 trios are better bought once a month of marking the bottle has told you what you consume.

A note from Sonal
I get this question in a tone I recognise, which is the tone of somebody who has been shown a cost-per-use table somewhere and cannot make it agree with the prices on our own pages. The reason it will not agree is that the table had a number in it which we do not publish. We publish what we know. We price the unit, we price the refill, and we stop - because how fast a bottle empties in your vehicle depends on your parking, your climate, your doors opening and in the case of a spray on how often your hand reaches for it, and I have no way of knowing any of that.
So I would rather hand you a method than a figure. Read the two lines we do publish, and read line two properly, because it is the one almost nobody checks and it is the one that goes on being paid. On the hanging format it is genuinely lower than starting again, which surprises people enough that it has a page of its own. Then establish the third line yourself on the cheapest thing in the range. A pen mark and a date is not a scientific instrument but it is honest, and in a month it will tell you more about your own consumption than any published claim could.
The one thing I will not do is convert grams to millilitres so that a table looks complete. Our car perfumes are sold by volume and our waterless refills by weight, and the conversion between them is not something you can assume without knowing the density of the specific oil. A comparison with an invented number in it is worse than a comparison with a gap in it, because the gap is visible. Write to me with your driving hours and your parking and I will tell you which line is going to dominate your total - and if it turns out to be line one, I will tell you to buy the ₹449 bottle and stop reading.
Frequently asked questions
How should I compare the true cost of car perfume spray, hanging perfume and a waterless diffuser?
Grade three lines rather than averaging them. Purchase price is verified: 12ml car perfume ₹449 to ₹549, a 50 ML Car Perfume Spray ₹1,499, Safar ₹3,999 or ₹4,499. Refill price is verified: 15ml hanging refills ₹399 to ₹449, waterless refills ₹1,049 per 100 gm. Consumption rate is published nowhere for any format, so measure that line in your own vehicle before comparing totals.
Why does SOSA not publish a cost per use for its car fragrances?
Because the figure that would complete the sum does not exist. SOSA publishes no duration for a 12ml unit in either form of release, none for the 20ml bottle supplied with Safar, and none for what any speed setting draws while running. Cost per use needs that multiplier. Any page that gives you one has assumed a week, a climate and a parking situation it did not show you, and those three things change the answer enormously.
Can I compare the car perfumes and the waterless refills on cost per millilitre?
Not honestly. The car perfumes are sold by volume in millilitres and the waterless refills by weight in grams, and there is no published conversion between the two. Converting would require assuming the density of the specific oil. Compare within one system, where the units agree, and compare across systems on purchase price, refill price and how often each is consumed in your own week instead.
Which cost line matters most when comparing SUV fragrance formats?
Whichever one recurs. Purchase price is paid once and its weight in the total shrinks over time, while refill price is paid again and again and its weight grows. That is why the gap between a ₹399 hanging refill and a ₹1,049 waterless refill matters more over a long relationship than the gap between a ₹449 bottle and a ₹3,999 device, provided you keep refilling.
Does free shipping affect the true cost of a cheap car perfume?
It can, and it is the only logistics fact SOSA publishes. Free shipping applies above ₹499, so a jasmine at ₹449, a sandalwood at ₹479 or an icy mint at ₹489 does not reach the threshold on its own, while a vetiver khus at ₹509, a discovery trio from ₹699 or a Safar at ₹3,999 clears it. No shipping figure is published for purchases below the line, so none is quoted here.
Three cost lines, graded honestly
SOSA — Car Fragrance for the reader who has worked out that purchase price is the wrong comparison
Purchase price is published: 12ml car perfume ₹449 to ₹549 in either form of release, a 50 ML Car Perfume Spray ₹1,499, discovery trios ₹699 to ₹899, SOSA Safar ₹3,999 or ₹4,499. Refill price is published: 15ml hanging refills ₹399 to ₹449, waterless refills ₹1,049 per 100 gm and ₹1,849 per 300 gm. Consumption rate is published nowhere, and no page here invents it. The car perfumes are sold by volume and the waterless refills by weight, so no cost per millilitre spans both. Composed in India, free shipping above ₹499.

Editorial standards & sources
About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. The reasoning here - occupied cabin hours, evaporation while parked, airflow, exposure time and olfactory adaptation - applies to any brand; the products and prices are SOSA’s. Where SOSA publishes no figure, this guide says so and gives a way to measure it in your own vehicle rather than quoting a number.Facts verified 3 October 2026 against the live SOSA product pages: SOSA car perfume is sold as one 12ml product in two formats at the SAME price, listed on the product page as "Spray (Strong scent-throw)" or "Hanging (Mild scent-throw)", with a "50 ML Car Perfume Spray" at ₹1,499. The nine scents are Jasmine ₹449, Lavender ₹479, Sandalwood ₹479, Icy Mint ₹489, Lemon ₹499, Vetiver khus ₹509, Sea Breeze ₹509, Oud ₹509 and Mysore Orange Blossom ₹549, the last of which is spray only. Car Hanging Freshener Refills are 15ml at ₹399 to ₹449 in eight scents - a larger bottle than the 12ml unit they refill. The SOSA Safar waterless car and travel diffuser is ₹3,999 for the SOSA scent trios and ₹4,499 for the hotel-inspired trios, with three speed settings, an auto shut-off timer at one, two or three hours, up to ten hours continuous or thirty hours intermittent per charge, a 2000 mAh battery, Type-C charging, a body of about 9 cm that fits a cup-holder, and a 20ml bottle in the box; it diffuses pure undiluted oil cold, with no water and no heat, and the product page states "Aroma only - does not humidify", which is not a claim that it dries a cabin or corrects damp. SOSA publishes NO coverage figure for Safar - no square feet, no cubic metres and no seat count - so no page here sizes it to a vehicle. Waterless Nebuliser Refills are shared with the SOSA Vaayu at ₹1,049 per 100 gm and ₹1,849 per 300 gm for the SOSA scents, and ₹1,099 and ₹1,899 for the hotel-inspired scents; that range contains no oud and no lavender, while the 12ml range contains both. The car perfumes are sold by volume and the waterless refills by weight, so a cost per millilitre across the two systems is not available from the published figures and none is given here. SOSA publishes no duration figure for a 12ml unit, a 20ml Safar bottle or any speed setting. No SOSA product removes an odour at its source: food, damp and smoke in a cabin are cleaning and ventilation problems, and fragrance sits on top of whatever is already there. SOSA makes no claim about mood, alertness, concentration, wellbeing or driving, and no claim about air quality or purification. After-sales terms, bulk arrangements and delivery commitments are confirmed with SOSA directly; free shipping above ₹499 is the only logistics fact stated. The hotel-inspired scent names are SOSA’s own interpretations and catalogue variant names; SOSA is independent and not affiliated with any hotel or brand named for reference.
