Which figure should I measure against? The one in the product description, because it is the one published consistently across the whole range and in the structured data: 4 to 6 weeks, approximately 28 to 42 days, of continuous diffusion per 12ml hanging bottle, and 100 sprays per 10ml spray bottle with 3 to 4 hours per application. If you were well short of those, that is a real complaint.
And if the figures agree and I am still short? Then work through the genuine variables: outdoor parking and heat, how much outside air moves through the cabin, the stopper setting on a hanging bottle, and your own dose. Those are real and all of them are free to change. They are an explanation, not an excuse, and they do not cancel a published figure.

2. On SOSA's pages, specifically: three scents carry more than one figure. Icy Mint and Lavender each publish 4 to 6 weeks, about 28 to 42 days, in body copy and structured data, and also publish 2.5 months, 10 to 11 weeks and up to 75 days elsewhere on the same page. The Lemon page publishes 28 to 42 days in its description while its search-engine title and description publish 60+ days and a 75-day life. The spread is roughly double.
3. The figure to hold us to is the one in the product description. 4 to 6 weeks, approximately 28 to 42 days, of continuous diffusion per 12ml hanging bottle, and 100 sprays per 10ml spray bottle with 3 to 4 hours per application. Those are the figures published consistently across every scent page and in the structured data, and they are the ones that belong in a complaint.
4. Then the genuine variables, which explain a shortfall without excusing one. Outdoor parking and heat, how much outside air moves through the cabin, the stopper setting on a hanging bottle, and your own dose. All four are real, all four are free to change, and none of them turns a figure that was not met into a figure that was.
5. And if you were well short of the description figure, say so. A published figure is a published figure. If a 12ml hanging bottle was empty in a fortnight in a basement-parked car with the stopper tight, that is not something a variables list should be used to argue away, and we would rather hear it.
Every figure quoted here is from SOSA's own live pages. No brand of car perfume other than SOSA is named on this page, and no longevity figure is claimed or implied for anybody else's product.
First question: which claim are you measuring against
One piece of housekeeping first, because it shapes every sentence underneath. This page names no brand of car perfume, including the one you are holding. Not to be coy: because we have not tested it, hold no verified figure for it, and have no business telling you how long somebody else's bottle lasts. You will also not find the usual line about what a typical car freshener manages, because that figure is always quoted about products nobody measured. Everything factual here is either about formats, which behave the way they behave whoever made them, or about what SOSA publishes about SOSA's own products, which you can go and read for yourself.
Now the structural point, and it is the reason this question is so common. A product in this category carries longevity figures in four separate places, and they are not written at the same time or by the same hand. There is the product description, which is the considered version. There are section headings inside the page, which are written to be read quickly. There is the product title, which has to fit in a line. And there are the search-engine title and description fields, which most buyers read first and which are often the oldest text on the page because nobody looks at them again.
Which means the figure in your head and the figure the manufacturer is standing behind can be two different numbers, and you may never have seen the second one. That is not a description of other people's pages. It is true of three of ours, and the rest of this page sets out exactly where.
Our own pages, with every figure and where it sits
Here is the full list, verified on the live store in October 2026. It is published in SOSA's own voice in every case and we are not going to quote you the longest one. Where a page disagrees with itself, both halves are in the table.
| Where it is published | What it says | What to do with it |
|---|---|---|
| Product description and structured data. All eight scent pages and the refills page | 4 to 6 weeks, approximately 28 to 42 days, of continuous diffusion per 12ml hanging bottle. The refill is published at the same 4 to 6 weeks per fill | This is the figure to measure against. It is the only hanging figure published consistently across the whole range, and it is the one in the structured data |
| A section heading. Icy Mint and Lavender pages | 2.5 months | Roughly double the same page's description figure. Both cannot be true. We are correcting the heading, not the description |
| Body copy on the same two pages | Holds for 10 to 11 weeks, and a worked daily rate of about 0.16 ml a day across the 12ml bottle giving up to 75 days of active life | Also roughly double, and arithmetically incompatible with 28 to 42 days for the same 12ml volume. Do not measure against it |
| Search-engine title and description fields. Lemon page | Lasts 60+ Days and 75-day life | Longer than the same product's own description, which says 28 to 42 days. This is the text a search result shows you first, which is exactly why it misleads |
| Spray figures, all pages | 100 sprays per 10ml bottle. About 50 days at two sprays a day, three months and above at one a day. 3 to 4 hours of persistence per application | Internally consistent everywhere, and a count of your actions rather than of days. Measure against it by counting sprays, not weeks |
One more, for completeness, because it is the same category of error in a different field. The Lemon page's body copy prints ₹449 in four places while the variant actually sells at ₹499, and its published cost per spray of approximately Rs 4.49 is derived from the stale figure. We would rather you heard that from us than discovered it at checkout. The live prices are in the table further down.
The figure to hold us to, and why it is that one
The rule we would apply to ourselves, and that you can apply to anybody: the figure in the product description is the one the seller is standing behind in full. It is the longest-form, most-reviewed text on a product page, it is what goes into the structured data a search engine reads, and it is the version that has to survive being read slowly. A heading is written to be read in half a second and a metadata field is written once and forgotten.
And the format the word replacing usually means. The hanging bottle is 12ml of refillable glass, published at 4 to 6 weeks, approximately 28 to 42 days, of continuous diffusion per bottle, from ₹449 by scent. It is topped up from a 15ML refill at ₹399 to ₹449, published at the same 4 to 6 weeks per fill because it is a full 12ml of the same oil with a little to spare. The only intensity control SOSA publishes for it is the stopper: "Adjust the stopper to control intensity. Loosen for stronger throw, tighten for subtler. Start tighter; open gradually until you find your level." Published placement is "Hang from your rear-view mirror or in a well-ventilated position", and the pages add "Avoid direct contact with leather, fabric, or dashboard." SOSA publishes that its car range is spray or hanging only, so there is no vent clip and no plug-in in it.
What SOSA publishes about its own spray, which is the only consumption data in this comparison that exists as a number you can check. 100 sprays per 10ml bottle. Approximately 50 days at two sprays a day. Three months and above at one spray a day. 3 to 4 hours of persistence per application. Different scent pages publish their own cost per spray, from approximately Rs 4.49 to approximately Rs 5.09. One limit travels with all of it: the 10ml spray is published as single-use - "The Spray bottle (10ml) is currently single-use; a refill program is in development." A spray owner does not top the bottle up, and nothing on this page will tell them they can.
Now the thing that explains most of these searches, and it is not a quality problem. The two common car fragrance formats are sold in different units, and the units are measuring different things. SOSA publishes its spray at 100 sprays per 10ml bottle. That is a count of your actions. It goes down when you press it and at no other time. SOSA publishes its hanging bottle at 4 to 6 weeks, approximately 28 to 42 days, of continuous diffusion per 12ml bottle. That is a span of calendar time. It goes down while the days pass, whether the car moved that week or sat in a basement. Those two numbers do not share a denominator. One counts presses and the other counts days, and no amount of arithmetic turns one into the other.
The genuine variables, which are not an excuse
Now the variables, with one condition attached. They explain variation around a published figure. They do not convert a figure that was not met into one that was. A seller who answers every shortfall with a list of things the buyer might have done wrong has stopped publishing a figure and started publishing an alibi, and the difference matters.
If it under-delivered, you are entitled to say so
This is the part most pages on this subject leave out. A published longevity figure is a statement, and a buyer who did not get it has a complaint rather than a misunderstanding. If a 12ml hanging bottle published at 28 to 42 days was dry in a fortnight, in a basement-parked car, with the stopper tight and no unusual heat, then no amount of airflow discussion is relevant. Say it to whoever sold it to you, and say it in the published unit so the conversation has somewhere to go.
The useful shape for that sentence is: the description says 28 to 42 days of continuous diffusion, I got fifteen, the stopper was tight and the car parks underground. That is checkable, it names the figure being measured against, and it does not depend on anyone agreeing about how a cabin smells. Do the same with a spray by counting presses rather than days, because that is the unit it is sold in: if a bottle gave you sixty presses rather than a hundred, that is the number to quote.
What this does and does not justify spending
Nothing, in most cases, and that is the honest end of this page. A measurement problem is not solved by a purchase. If the figures agreed and you were short, work the four variables, all of which are free. If the figures did not agree, you now know which one to use, and the next bottle you buy will be judged against the right number rather than the biggest one.
The one case where this page points at money is narrow and cheap: if the published figure is genuinely fine for you and the repeat purchase is the irritation, the hanging bottle is refillable by design and a 15ML refill is published at ₹399 to ₹449 at the same 4 to 6 weeks per fill. That is a cost question, not a longevity one, and it has its own page in this block.

I would rather publish this page than have somebody find it out on their own. Two of our scent pages carry a heading claiming 2.5 months above body copy that says 4 to 6 weeks, and our lemon page's search-engine fields say 60 days and more while its own description says 28 to 42. They were written at different times and the longer numbers came from a draft that should never have gone live.
The figure I stand behind is the one in the description. A 12ml hanging bottle diffusing continuously gives 4 to 6 weeks, and the spray gives 100 presses at 3 to 4 hours each. Everything above that is somebody being optimistic in a headline, and if you measured against a headline and felt short-changed, the fault is ours and not your nose.
So hold us to 28 to 42 days and to 100 sprays. If you did not get them, write and say so in those words, because that is a sentence I can do something with. And if a list of variables is ever offered to you instead of a number, by us or by anybody, that is the moment to ask which figure was published in the first place.
