SOSA Safar waterless car perfume diffuser showing its 20ml bottle and controls

Can I set a preferred intensity on Safar without assuming the same setting feels identical across every fragrance?

Speed two is a setting, not a strength figure

You can set a speed and leave it there, and that is the whole of what the control offers. What it does not come with is an exchange rate between a setting and a scent.

The reason this question is worth a page is that a number invites arithmetic. Three speeds look like a scale, and a scale looks like it should be comparable across the range. It is a scale on the device and nothing more than that, and SOSA publishes nothing that would let it mean more.

SOSA Safar, ₹3,999. Three speed settings and a one, two or three hour auto-off timer, chosen by hand each time you switch it on.

The answer in 30 seconds

Can I set a preferred intensity on Safar without assuming the same setting feels identical across every fragrance?

  • In one line. Set a speed and keep it. Just do not read it as a strength figure that travels across the nine scents.₹3,999
  • The short answer. Yes, you can set a preferred speed and keep it. What you cannot do is read the setting as a strength figure: SOSA publishes three speed settings and nine scent names, and no strength ranking of those scents. Safar is Rs 3,999 and the nine car scents run Rs 459 to Rs 559.
  • If you only do one thing: change one variable at a time. A new oil and a new speed in the same week tells you nothing about either.
  • Can I set one preferred intensity and leave it? Yes. Pick one of the three speeds, set the one, two or three hour auto-off timer or leave it off, and that is the routine. You still switch it on and choose each time, because choosing is part of running it.
  • Does speed two mean the same thing with every scent? Not in any sense SOSA publishes. Speed two is a setting on the device. How a given oil lands in your cabin at that setting is not something SOSA measures or states, in either direction.
  • So how do I find my own setting? One oil at a time and one speed at a time, over a week of ordinary driving. Your own nose in your own car is the only instrument in this, and it is a good one.

The answer, in full

Yes, and the two halves of that sentence are both worth saying. You can set a speed: there are three, you pick one by hand when you switch the unit on, and nothing obliges you to change it again. What you cannot do is treat that number as a measurement. SOSA publishes no strength ranking of the nine car scents, so there is no conversion between a setting and a scent, and no published figure for what any speed does to the air in any cabin. Speed two is a setting on the device. What it does with whichever oil is in the 20ml bottle, in your car, on your route, is yours to find out. The method is dull and it works: one oil, one speed, one week, then change one thing. A portion of every SOSA order supports girl-child education through Nanhi Kali.

What a setting is, and what it is not

Two published facts and one published absence. The facts are the controls on the device; the absence is any ranking of the scents, and the absence is what makes the second half of the question a good one.

The setting: three speeds, chosen by hand, every run

Safar publishes three speed settings and a one, two or three hour auto-off timer. You switch it on, choose a speed, choose a timer setting or leave it off. Nothing on the published specification stores a choice for you, so choosing it is part of running it rather than a thing you do once.

A setting is a position on a device, not a figure about a smell.

The gap: no strength ranking of the nine scents

SOSA publishes nine car scent names, the formats each comes in, the price of each, and a Fragrance Pyramid and Scent Family on every one of the nine scent pages. What it publishes nowhere is a strength ranking of them, a concentration figure, or any figure for how one of them behaves in a cabin. A pyramid tells you the direction a scent takes; it does not put a number on it. So there is no published strength to carry from one scent to the next, and a page that offered you a conversion table would be inventing it.

The method: one oil, one speed, one week, then one change

Fill the 20ml bottle with one oil. Run the lowest speed for a week of your ordinary driving and change nothing. Then change one thing: the speed, or the oil, never both. Write the pair down on a note in the door pocket. After a month you will have your own short table, which is the only one that was ever going to be true for your car.

Dull, cheap, and the only method that answers the question.

Nine scents, one dial, and no conversion table

Speed two with Oud and speed two with Icy Mint are the same setting on the same device. SOSA publishes no strength ranking of the nine, so nothing tells you how either one will land in your cabin, and nothing tells you that they land differently either. Your own nose, your own car, your own note in the door pocket.

Working through the nine rather than guessing? The three spray discovery sets are ₹709 to ₹909, and the pack of nine sprays is ₹3,009. See the discovery sets →

What transfers between scents, and what does not

What the record says
The speed setting itself It transfers exactly, because it is a setting on the device rather than a property of the oil. Speed two is speed two whatever is in the 20ml bottle.
How that setting lands in your cabin Not published, in either direction. SOSA states nine scent names and no strength ranking, so there is no figure to carry from one scent to the next.
The one, two or three hour auto-off timer It transfers too. An auto-off setting is a length of time and has nothing to do with which oil is in the bottle.
Your own preferred level That is yours, and it may well be a different speed for a different oil. Nothing published says it should be the same, and nothing published says it should differ.

One practical consequence. If you rotate oils, expect to re-find the setting each time rather than assuming last month's answer holds, and to take the re-finding as part of the rotation rather than as a fault. SOSA publishes no oil-consumption rate either, so if you want to know what a setting costs you in oil, mark the level on the bottle, log the date and mark it again after your ordinary month.

“A dial on a device is a dial on a device. It is not a measurement of a scent, and no published figure turns it into one.”

Finding your own setting, scent by scent

  1. Fill the 20ml bottle with one oil and run the lowest speed for a week.
  2. Change one thing at a time: the speed, or the oil, and never both.
  3. Write the scent name and the speed on a note in the door pocket.
  4. Expect a different answer for a different oil, and let it be different.

Questions, answered

Is speed two stronger with one scent than with another?
SOSA publishes no strength ranking of the nine car scents, so there is no published answer in either direction. Speed two is a setting on the device, and what it does with a particular oil in your cabin is yours to find out.
Will I have to choose the speed again every time I change oil?
You choose a speed every time you switch the unit on, so in practice you choose it anyway. Nothing on Safar's published specification stores a setting, which is why choosing is part of running it.
Should I use a different speed for a different scent?
You may well want to, and SOSA publishes nothing that says you should or should not. That is your nose in your car, which is the only place this question has ever been answerable.
Does SOSA publish which of the nine is strongest?
No. There is no strength ranking anywhere in the product records, which is why you will not find one on this page either. What is published is nine names, the formats and the prices, from Jasmine Rs 459 to Mysore Orange Blossom Rs 559.
What if the setting I like empties the bottle faster?
SOSA publishes no oil-consumption rate, so there is no published figure for what any speed does to the 20ml bottle. Mark the level with a marker pen, log the date, run your ordinary month and mark it again. That number is yours and it is the only true one.
