Cheaper and still good: ₹1,899 for one Sukoon; ₹749 for reeds alone.
Running cost: one 300ml 300ml refill at ₹1,799 serves both rooms for months — roughly ₹6 per ml against about ₹20 in 15ml bottles.
2. ₹1,899 is a complete purchase, not half of one. One Sukoon with three 15ml bottles does one room properly. If the second room genuinely does not matter to you, stop here and spend nothing further.
3. ₹749 is the honest floor. A reed diffuser scents a corner rather than a room, needs no socket and no routine, and in a 110–140 sq ft bedroom that is a reasonable amount of fragrance for very little money.
4. ₹5,597 is the top of the sensible range. Two Sukoons plus the Pack of 7 × 15ml at ₹1,799 — every scent in the collection, and enough variety to rotate seasonally for years.
5. The running cost is one bottle, not a subscription. A 300ml 300ml refill at ₹1,799 works out at roughly ₹6 per ml against about ₹20 per ml in 15ml bottles, and it serves both machines for months.

Three things that decide your number
Budgeting for home fragrance goes wrong in a specific way: people decide an amount first and then work out what it buys, which is how you end up with two machines and no fragrance you like, or five bottles and nowhere useful to run them. Three questions settle the number properly, and none of them is about money.
The five tiers, and what you actually get
Five real budgets, with the "what you actually get" column written the way I would say it to someone across a table rather than the way a price list would put it. The starred row is the recommendation; the rows above it are not failures.
| Tier | What you buy | What you actually get | Total |
|---|---|---|---|
| The floor | Reed diffuser only | One corner of one room, quietly. No socket, no routine, no control — and genuinely pleasant | ₹749 |
| One room | One Sukoon + 3 × 15ml scents included | One room done fully, with three fragrances to switch between. The other room smells of nothing | ₹1,899 |
| One room, settled | One Sukoon + a 300ml refill | The same one room, with a signature you never ration. Better than two machines if you only use one room | ₹3,698 |
| The whole flat ★ | Two Sukoons + 6 × 15ml included | Both rooms, permanently, a different scent in each, and no machine to carry | ₹3,798 |
| The whole flat, with a wardrobe | Two Sukoons + the Pack of 7 × 15ml | Both rooms plus every scent in the range — enough to rotate seasonally for years | ₹5,597 |
| Not this | Vaayu waterless nebuliser | Up to 1000m³ of connected space, which is several times this flat. The right machine, the wrong home | ₹11,999 |

What it costs per month to run
The ongoing cost of a Sukoon is fragrance, and nothing else worth budgeting for. I am not going to quote you an electricity figure, because I would be making it up — what I can tell you is that the machine is a small ultrasonic unit about 17cm tall, and in every household I have discussed this with, the power has never been the line anyone noticed. Water is water, ideally filtered or RO in cities with hard supply, which costs nothing you are not already spending. That leaves the bottles, and the bottles are arithmetic you can do yourself.
Here is the honest way to work it out, because how long a bottle lasts depends entirely on how you run the machine. A 300ml 300ml refill is ₹1,799 — roughly ₹6 per ml, against about ₹20 per ml if you buy 15ml bottles at ₹299. If that bottle lasts your household six months across two rooms, you are spending about ₹300 a month to keep an entire 1BHK fragranced. If it lasts a year — which it will if the bedroom machine runs on the 2H timer and the living room one only comes on in the evenings — you are at about ₹150 a month. Both of those are numbers I am comfortable putting in print because they are your own consumption multiplied by our published price, rather than a claim about how long a bottle lasts.
Two things reduce that figure and one thing raises it. Running on low rather than high is the big one: the same 500ml tank gives 16–18 hours on low against 9–12 on high, so the low setting nearly doubles what a fill does, and in a 110–140 sq ft bedroom low is the correct setting anyway. Using the timers is the second — a 2H run before bed is enough for a small room, and the machine stops itself. What raises the cost is buying in 15ml bottles for everyday use, which is a variety purchase priced at about ₹20 per ml being used as a staple. Keep the 15ml bottles for rotation and the 300ml refill for the scent you actually live in, and the running cost of a two-machine 1BHK settles somewhere most people find lower than they expected.
The SOSA 1BHK edit
The same five tiers as a buying order, so you can start anywhere on this list and move up it without wasting anything you have already bought.
| Buy | What it adds | When | Price |
|---|---|---|---|
| 1. Sukoon ★ | One room fully — 270–320 sq ft, three 15ml scents included | First, in the room with more waking hours in it | ₹1,899 |
| 2. A second Sukoon | The other room, permanently, plus three more 15ml scents | As soon as the quiet room starts bothering you | ₹1,899 |
| 3. 300ml refill | Your everyday scent for both tanks, at about ₹6 per ml | After a month, once one bottle has clearly won | ₹1,799 |
| 4. Pack of 7 × 15ml | The rest of the range, for seasonal rotation | Only if the flat feels samey rather than under-covered | ₹1,799 |
| 5. Reed diffuser / Boond | The entryway or the bedroom with no socket; the bathroom | As the stopgap early on, or the finishing touch later | from ₹749 / ₹899 |
| Not this: Megh or Vaayu | A 6-litre tank; a waterless nebuliser to 1000m³ | Megh only for a loft; Vaayu when you move somewhere with corridors | ₹3,499 / ₹11,999 |

I would like people to arrive at this page and leave having spent less than they planned, which is an odd thing for a founder to write and is nonetheless true. The commonest overspend in home fragrance is not a machine too many — it is the wrong ₹1,799: a Pack of 7 bought by someone who wanted a signature, or a 300ml refill bought in week one by someone who had not yet discovered which scent they actually use.
So the honest budget advice is this. Spend on machines according to how many doors you close, and on bottles according to what the first month teaches you. ₹3,798 is the right number for a 1BHK with a bedroom door that shuts, and it arrives with six fragrances, which means the second decision can wait until you have evidence rather than a preference. Nothing on the list gets more expensive for being bought later.
Everything is made and supported from Pune, and a part of every order funds girl-child education through Nanhi Kali. You get a home that smells like somewhere you chose; a girl gets a classroom. That equation has always felt right to me.
