The Megh is not really a fragrance purchase. It is a humidifier that also scents — and that is the only frame in which the price makes sense
Sukoon 500ml ₹1,899: 270–320 sq ft, 16–18 hours on low, remote, 7-colour LED, steady / 2H / 4H timers, three 15ml fragrances included.
Machine one
Sukoon ₹1,899
Megh 6L ₹3,499: up to 100 hours on a fill, and rated to 215 sq ft. It costs ₹1,600 more than the Sukoon and covers about a third less area.
Machine two
Megh ₹3,499
Tank size and coverage are barely related. Reach is set by how much mist leaves the machine each hour; the tank only decides how long it can keep going before a refill.

Start with a question that has nothing to do with fragrance: would you consider buying a humidifier for this room? If the answer is yes — a dry Delhi winter, an air conditioner running every night, a nursery — then the Megh at ₹3,499 is quietly good value, because it is a humidifier that also scents. If the answer is no, the comparison is already over, and the Sukoon wins on every measure that is left.
Quick answers — read this first
Coverage: Sukoon 270–320 sq ft, Megh up to 215 sq ft. The more expensive machine covers less floor.

Runtime: Sukoon 16–18 hrs on low; Megh up to 100 hrs. The Megh is filled weekly rather than nightly.

The real decision: one Megh ₹3,499 or two Sukoons ₹3,798. If you have two rooms, buy two Sukoons. If you have one dry room you want to leave running, buy the Megh.
The short answer
Short answer: The Sukoon at ₹1,899 for almost everyone. It covers more area (270–320 sq ft against 215), costs ₹1,600 less, includes three 15ml fragrances and runs 16–18 hours on low, which already carries a full night.
Buy the Megh when: You want one room to run for days without being refilled, and you want the humidity — a dry north-Indian winter, a bedroom with the AC on nightly, a room where dry air genuinely bothers you. The Megh is a six-litre humidifier that also scents, and judged that way ₹3,499 is reasonable.
The comparison people miss: One Megh is ₹3,499 and two Sukoons are ₹3,798 — ₹299 apart. One buys a hundred hours in a single room; the other buys two separate rooms. Most households need the second thing.

Straight answer
Should you buy a Sukoon or a Megh?
1. The Sukoon, on coverage and on price. Rated 270–320 sq ft against the Megh's 215, at ₹1,899 against ₹3,499, and it arrives with three 15ml Hotel Collection fragrances. For scenting an ordinary room, there is no measure on which the Megh is ahead.

2. The Megh, if you want a week of unattended running. Six litres and up to 100 hours means filling it on a Sunday and forgetting it until the next one. A Sukoon gives 16–18 hours on low, which covers a night but not a week. If refilling is the thing that stops you using a diffuser, that is a real argument.

3. The Megh, if the room is genuinely dry. Six litres of water going into the air over a few days is meaningful humidification, not incidental. In Delhi or Chandigarh in January, or in a bedroom with the air conditioner on every night, that changes how the room feels to sleep in. In Mumbai in August it is the opposite of what you want.

4. Never the Megh for more coverage. It is the most common misreading in the range. ₹3,499 buys about a third less rated area than ₹1,899. Tank size sets how long a machine runs, not how far it reaches — reach comes from hourly output and from how the room distributes it.

5. And if you have two rooms, the answer is two Sukoons. Two Sukoons at ₹3,798 are ₹299 more than one Megh and solve two separate air spaces. A single machine of any size solves one. That ₹299 is the whole decision for most households, and it usually points away from the Megh.

Made in India, composed by an ISIPCA Versailles-trained perfumer — and a portion of every order supports girl-child education through Nanhi Kali.
TL;DR: the Sukoon covers more area for ₹1,600 less and is the right machine for scenting a room. The Megh buys two things fragrance has nothing to do with — a week of unattended running and real humidity in a dry room. If you would not consider a humidifier for that room, buy Sukoons.

SOSA Sukoon · 500ml ₹1,899
Rated 270–320 sq ft — about a third more than the Megh — with 16–18 hours per fill on low, 9–12 on high, a remote, a 7-colour LED, steady / 2H / 4H timers and auto shut-off. Three 15ml Hotel Collection fragrances in the box, so ₹1,899 is a finished setup. Two of them cost ₹3,798 and cover two separate rooms.

Why the bigger machine covers less floor

The instinct that a larger tank must mean a larger room is so natural that it takes a moment to see why it is wrong. In an ultrasonic diffuser, the reservoir and the reach are almost unrelated quantities. What sets reach is the volume of mist leaving the machine each hour and how well that mist distributes through the air of the room — a function of the plate, the output rate and the airflow around it. What the tank sets is endurance: how many hours the machine can keep producing that same output before somebody has to fill it again. A six-litre reservoir is a hundred hours of not thinking about the machine, not a larger footprint. The Megh is rated to 215 sq ft and the Sukoon to 270–320, and both numbers are honest descriptions of what each machine puts into the air per hour.

Which leads to the more interesting question: what is the six litres actually for? The answer is water in the room. An ultrasonic diffuser is a small humidifier that happens to carry fragrance, and a machine that can put six litres into the air across a few days is doing humidification at a scale a 500ml tank cannot approach. In a dry north-Indian winter, or in a bedroom where the air conditioner runs every night from March to October, that is a genuine comfort rather than a side effect — dry air is what makes an air-conditioned room uncomfortable at four in the morning. Read the Megh as a humidifier with a fragrance function and its price stops being strange. Read it as a bigger diffuser and it looks like poor value, because as a diffuser that is exactly what it is.

Three ways to read the pair

1
READING ONE · AS DIFFUSERS
The Sukoon wins, and it is not close
SOSA Sukoon 500ml diffuserSOSA Sukoon₹1,899Judged purely on the job of making a room smell of something, the Sukoon covers 270–320 sq ft against 215, costs ₹1,600 less, and comes with three 15ml Hotel Collection bottles in the box. Its 16–18 hours on low already covers an overnight run comfortably, and its 2H timer is the setting most people actually use — because a nose stops registering a constant scent within about twenty minutes, so a machine running for a hundred hours is producing a fragrance nobody in the house can still detect. Where the Sukoon loses: if you dislike refilling, you will be topping it up every day or two when running it long, and its humidity contribution is modest by comparison.
The number that matters: ₹1,899 with three fragrances included, against ₹3,499 without. That gap buys a lot of scent.
2
READING TWO · AS A HUMIDIFIER
This is where the Megh earns its price
Six litres released into a room over a few days is real moisture, and it changes how a dry room feels rather than merely scenting it. The households where I recommend the Megh without hesitation are the ones who already own or want a humidifier: a Delhi or Chandigarh bedroom in January, a room with the AC running from March through October, a nursery where dry air keeps waking somebody. Filling once a week instead of nightly is the second half of the appeal, and for people who abandon diffusers because of the refilling, it is the reason they keep using this one. Where the Megh loses: a coastal monsoon, where you will feel the added moisture on the bedlinen before you notice the fragrance, and any situation where the difficulty is more than one room.
The one-line test: would you buy a humidifier for this room anyway? Yes means the Megh is good value. No means it is not.

READING THREE · AS A BUDGET
One Megh, or two Sukoons, for the same money
This is the comparison most people are actually making without saying so. One Megh is ₹3,499; two Sukoons are ₹3,798. Two hundred and ninety-nine rupees apart, and the two purchases could hardly be more different. The Megh gives one room a hundred hours of scented, humidified air and leaves every other room exactly as it was. Two Sukoons give two rooms 270–320 sq ft of coverage each, two remotes, two timers, and six 15ml fragrances in the boxes — and they can be moved, so the second one goes into the guest room when somebody stays. In a flat with more than one room anybody sleeps in, the second option is nearly always the better spend.

Head to head, situation by situation

The honest verdict for each common case. Notice that the Megh wins only where the words dry, overnight or unattended appear — and that in every multi-room case the answer is Sukoons.

Sukoon or Megh
Which machine, for which problem
Your situation Sukoon ₹1,899 Megh ₹3,499 Buy
An ordinary bedroom or living room ★ 270–320 sq ft, 16–18 hrs, 3 scents included 215 sq ft, ₹1,600 more Sukoon
Two rooms to solve Two of them, ₹3,798 One machine, one room Two Sukoons
Dry winter bedroom, north India Modest humidity from 500ml Six litres of real humidification Megh

Coastal flat in monsoon Run short, three drops Adds moisture you do not want Sukoon, used sparingly
A large open living-dining zone 270–320 sq ft each; two placed apart 215 sq ft from one point Two Sukoons
You hate refilling tanks Every day or two on a long run Once a week Megh, if it is one room
The line to remember: the Megh covers less area than the Sukoon and costs more. It buys runtime and humidity in one room. For more floor, the answer is always another Sukoon.

The SOSA principle
The Megh is not really a fragrance purchase. It is a humidifier that also scents — and that is the only frame in which ₹3,499 for 215 sq ft is good value.
Which is why the deciding question is not about scent at all. Ask whether you would put a humidifier in that room, and the machine chooses itself.

Drops, moisture and where to stand a large machine

Dose per fill, not per litre. The Hotel Collection guidance is 3–6 drops per tank, and the temptation with six litres is to scale it up twelvefold. Do not. Five to six drops is the right figure for a Megh fill and three to four for a Sukoon, because what leaves each machine per hour is broadly similar and the fragrance is being metered out over days rather than all at once. Twelve times the drops in twelve times the water would give you the same concentration for a hundred hours, which sounds logical and produces a room nobody can smell any more and a bottle that empties in a fortnight.

Watch the moisture, and know when to stop. A Megh doing its job properly is putting real water into the air, and there is a point past which that stops being a comfort. The signs are easy to read: condensation on a window or a cold wall in the morning, a faintly clammy feel to bedding, or a musty note appearing where there was none. If any of those show up, run it fewer hours a day rather than abandoning it, and stop entirely during a coastal monsoon. Keep it away from wooden furniture and books, stand it on a tray or a hard surface rather than a rug, and leave a clear metre in front of the mist outlet so it disperses rather than settling on something.

And think about footprint before you buy. Six litres is a physically large object. A Sukoon is about 17cm tall and lives happily on a console or a chest of drawers; a Megh needs floor or a low sturdy surface and a socket near it, and it is not furniture you will move around casually. That matters more than it sounds, because one of the quiet advantages of the smaller machine is portability — a Sukoon migrates to the guest room for a weekend and back again, and two of them across two rooms give you a flexibility that a single large unit cannot. Both machines take the same water-based fragrance, so mixing them in one home costs nothing in bottles.

₹3,499 buys one room, all night, for a week. ₹3,798 buys two rooms. That ₹299 is the entire decision.

One room ★ Sukoon ₹1,899 — 3 × 15ml scents included 270–320 sq ft, 16–18 hrs ₹1,899
One dry room, all week Megh ₹3,499 — 6 litres, up to 100 hrs Up to 215 sq ft ₹3,499

Running cost, either A 100ml refill ₹999, or 300ml ₹1,799 (~₹6/ml) Months at 3–6 drops from ₹999
Honest notes before you buy: both machines are ultrasonic and take the same water-based Hotel Collection at 3–6 drops per tank, so owning one of each costs nothing extra in fragrance — 15ml ₹299, 100ml ₹999, 300ml ₹1,799, Pack of 7 ₹1,799, refills from ₹999. Every Sukoon includes three 15ml bottles of your choice. The Megh covers up to 215 sq ft against the Sukoon's 270–320 — it is bought for runtime and humidity, never for area, and for more floor the answer is another Sukoon. Ultrasonic output is mostly water, so both add humidity and the Megh adds a great deal more: welcome in a dry or air-conditioned room, unwelcome in a coastal monsoon. Neither takes neat oil, which will not atomise and will film the misting plate, and neither fragrance range crosses over to the waterless Vaayu (₹11,999) or Aangan (₹25,999). The machines are imported from China; the fragrances are composed and made in India. Use filtered water in hard-water areas, rinse the tank between scents, and keep fragrance out of reach of children and pets.

A note from Sonal

The most useful thing I can tell you about the Megh has nothing to do with fragrance. Ask whether you would buy a humidifier for that room, and answer honestly. In a Delhi January, or a bedroom that runs the air conditioner two hundred nights a year, most people would say yes without thinking of it as a purchase related to scent at all. That is the Megh's customer.

Everyone else is better served by two Sukoons, and the arithmetic is almost comic in how close it is — ₹3,798 against ₹3,499. For three hundred rupees you go from one room handled thoroughly to two rooms handled well, with two remotes, two timers and six bottles of fragrance in the boxes. I have never regretted pushing someone towards that, and I have occasionally regretted not pushing harder.

What I will not do is describe the Megh as a step up in coverage, because it is not one, and the coverage figures are printed where anyone can check them. It covers less than the machine below it in the price list. That is not a flaw — it is what happens when a product is designed around a tank rather than a room — but it has to be said out loud every time. A portion of every order funds a girl's classroom through Nanhi Kali.

Frequently asked questions

Is the Megh better than the Sukoon?
For scenting a room, no — the Sukoon covers 270–320 sq ft against the Megh's 215, costs ₹1,899 against ₹3,499, and includes three 15ml fragrances. The Megh is better at two different things: running for up to 100 hours without a refill, and putting real humidity into a dry room. Judge it as a humidifier that also scents and it makes sense.
Why does the Megh cover less area than the Sukoon?
Because tank size and coverage are largely unrelated in an ultrasonic. Reach is set by how much mist the machine puts out per hour and how it distributes through the room; the reservoir only decides how long that output can continue before a refill. Six litres is a hundred hours of endurance, not a larger area.
Can the Megh run all night in a bedroom?
Easily — it is rated for up to 100 hours, so a night is a small fraction of a fill. Whether it should is a separate question: a nose adapts to a constant scent within about twenty minutes, so the fragrance value of an all-night run is limited. The humidity value is real, and in a dry room that is usually the reason to do it.
Should I buy a Megh for a large living room?
No. A large living room is a coverage problem, and the Megh is rated to 215 sq ft — less than a Sukoon. Two Sukoons at ₹3,798, placed apart in the space, will do far more than one Megh standing in a corner. If the room is also double-height, no ultrasonic will hold it and the answer is a waterless machine.
Do the Sukoon and the Megh use the same fragrance?
Yes. Both are ultrasonic and both take the water-based Hotel Collection — three to four drops per tank in a Sukoon, five to six per fill in a Megh. One 300ml bottle at ₹1,799 will supply both for months. Neither takes neat oil, which is for the waterless machines only.
Sukoon vs Megh · the verdict
More area for less money — unless you wanted a humidifier all along
Sukoon ₹1,899 covers 270–320 sq ft, runs 16–18 hours on low and includes three 15ml Hotel Collection fragrances; two of them are ₹3,798 and solve two rooms. Megh ₹3,499 runs up to 100 hours and humidifies one dry room properly, at 215 sq ft. Both take the same water-based fragrance.
