"Bought the Sukoon for my AC bedroom. It runs the whole night on low, the 7-colour light is a lovely night light, and the remote means I set the timer from bed. Came with three hotel-inspired fragrances so I used it the first evening."
Sukoon 500ml Diffuser
★★★★★
"The Boond lives on my work desk - tiny, USB-powered, whisper-quiet. A little cool mist and a soft glow while I work, and it switches off on its own when empty. Best ₹799 I have spent for my cabin."
Boond 300ml Mini Diffuser
★★★★★
"Megh has a 6-litre tank and honestly lasts for days. Our living room was bone-dry from the AC and this fixed it - quiet, one simple dial, and it doubles as an aroma diffuser with the SOSA fragrance."
Megh 6L Diffuser
★★★★★
"What sold me: it is made for the SOSA water-based fragrance. I had clogged my old diffuser with thick essential oils - this mists cleanly and the Four Seasons-inspired scent is gorgeous. I just add a few drops to the tank."

What should I look for in diffuser warranty online? Clarity over big numbers. Check who honours it (the seller or a distant factory), what it actually covers (transit damage, defects, or nothing), the time window to report, and whether there is a real person to contact.
What voids most diffuser warranties? Misuse - and the most common misuse is running thick raw essential oils that clog the plate, or using hot water. Use only SOSA water-based fragrance in clean room-temperature water to keep your unit healthy.
Facts verified June 2026: SOSA makes three cool-mist ultrasonic diffusers: Boond (300ml, USB, colour night light, up to 6 hrs, ~150 sq ft, ₹799), Sukoon (500ml, 7-colour LED, remote + 2H/4H timers, up to 16-18 hrs, 270-320 sq ft, BPA-free, ₹1799) and Megh (6L, adjustable mist dial, ~35 dB, up to 100 hrs, ₹3499). Each is cool mist (no heating element) with auto shut-off, ships with 3 water-based Hotel Collection fragrances (15ml ₹299 / 100ml ₹999 / 300ml ₹1799), and is made for Indian AC-dry and winter air. Use SOSA water-based fragrance only; raw essential or carrier oils can clog the ultrasonic misting plate. Composed in India; a portion of every order supports Nanhi Kali girl-child education.

Warranty and support on ultrasonic diffusers sold online in India
Warranty is where a lot of online diffuser listings quietly overpromise, and I would rather be straight with you. SOSA does not advertise a multi-year manufacturer warranty, because I will not print a number I cannot honour. What we do offer is a no-questions-asked replacement if your diffuser arrives damaged in transit, and real support you can email. Here is how to judge warranty and support on any diffuser you buy online, and exactly what we cover.
Quick answers — read this first
What warranty does SOSA offer on its diffusers? An honest one: if your diffuser arrives damaged in transit, report it within 48 hours and we will arrange a replacement.

Straight answer
What warranty comes with an ultrasonic diffuser bought online in India?
It varies wildly, and many listings overstate it. Some quote a manufacturer warranty that is hard to claim against a distant factory; others say nothing at all. SOSA takes a deliberately honest position: we do not advertise a multi-year manufacturer warranty, because I refuse to print a promise I cannot reliably keep. What we do stand behind is a no-questions-asked replacement if your diffuser arrives damaged in transit - just report it within 48 hours of delivery - plus real support you can email, dispatch within 24 hours from Pune, and free shipping above ₹500. When you compare diffusers, judge the support you can actually reach, not the biggest number on the page.
SOSA cover: replacement if damaged in transit, reported within 48 hours. No invented multi-year warranty.

What to look for in warranty and support
Warranty language online is often designed to reassure rather than to inform. Here is how I would read it if I were buying, from any seller.
Four questions to ask of any warranty
Who honours it - the seller you can reach, or a factory you cannot? What does it actually cover - transit damage, manufacturing defects, or effectively nothing? What is the window to report a problem? And is there a real human to contact when something goes wrong?
Who honours it. A big "1-year warranty" badge is worthless if the only route to claim it is a factory that never replies. Support you can actually reach - an email that a person answers - is worth more than a long number nobody stands behind.
What it covers. The single most useful cover for a fragile, water-filled gadget shipped across the country is transit-damage replacement. That is the failure most likely to happen and least your fault. Manufacturing-defect cover is a bonus; "no cover" is a red flag.
Be honest with yourself about wear-and-tear too. An ultrasonic plate is a consumable-adjacent part: treated well it lasts for years, but run thick raw oils or hot water through it and no warranty will save it. Care is the real warranty.
The reporting window. Most fair policies ask you to inspect and report damage quickly - often within a day or two - because that is when transit damage is provable. Note the window and open the box promptly.
What SOSA actually covers
Let me be completely clear, because vagueness here helps no one.
Myth: every online diffuser comes with a solid multi-year manufacturer warranty.
Reality: many of those badges are unenforceable. SOSA deliberately does not claim one. Instead we promise what we can truly deliver: a replacement if your unit is damaged in transit, reported within 48 hours of delivery.
Reality: many of those badges are unenforceable. SOSA deliberately does not claim one. Instead we promise what we can truly deliver: a replacement if your unit is damaged in transit, reported within 48 hours of delivery.
| SOSA covers | SOSA does not claim |
|---|---|
| Replacement if damaged in transit (report within 48 hrs) | A multi-year manufacturer warranty we cannot honour |
| Real support you can email | Cover for misuse (raw oils, hot water) that damages the plate |
| Dispatch within 24 hrs; free shipping above ₹500 | Guarantees about scent lasting forever - fragrance is a consumable |
How to keep your unit healthy (and any cover valid): use only SOSA water-based Hotel Collection fragrance, filled into clean room-temperature water - filtered or RO in hard-water cities. Never pour in raw essential oils, perfumes or carrier oils, and never use hot water. Cool mist, no heat. Do that and the diffuser will serve you for years.
That is the whole truth of it. I would rather you trusted a modest promise we always keep than a grand one we would have to wriggle out of. If a competitor truly offers more and can honour it, buy theirs happily - but read the claim carefully first.
The SOSA range
SOSA makes three cool-mist ultrasonic diffusers for different rooms, each arriving with three of our water-based Hotel Collection fragrances so you can scent from day one. Prices and headline specs below are live from the SOSA store. Whichever you choose, use only the SOSA water-based fragrance - raw essential or carrier oils can clog the misting plate.

A note from Sonal
I trained as a perfumer at ISIPCA in Versailles, but half the questions we get are not about scent at all - they are about the machine. Indian rooms are bone-dry from AC and winter, and most gadget diffusers are too small, too loud, or quit by midnight. So we made three: Boond (300ml, desk), Sukoon (500ml, bedroom, with a remote and mood light) and Megh (6L, whole-room), each shipping with three of our fragrances.
They are cool-mist ultrasonic diffusers - an ultrasonic plate turns water into a fine, cool mist with no heating element, so there is no boiling water or burn risk, and each has an auto shut-off when the tank runs dry.
One thing I say on every listing and will say here: use only SOSA's water-based Hotel Collection fragrance. Raw essential oils, perfumes and carrier oils are thick or solvent-heavy and can clog the misting plate and damage the unit. A few drops of our water-based fragrance in the tank mists cleanly and scents the whole room.
Frequently asked questions
Does SOSA give a 1-year or multi-year warranty on diffusers?
No, and we say so honestly. We do not advertise a multi-year manufacturer warranty because we will not print a promise we cannot reliably keep. We do replace units damaged in transit if reported within 48 hours of delivery, and we back every order with real support.
What do I do if my diffuser arrives broken?
Report it to us within 48 hours of delivery and we will arrange a replacement. Keep the packaging and, if you can, a photo of the damage - it helps us sort it quickly.
Will my warranty or replacement cover clogging from oils?
No. Running thick raw essential oils, perfumes or carrier oils, or using hot water, is misuse and damages the plate. Use only SOSA water-based fragrance in room-temperature water to keep your unit healthy.
How fast does SOSA ship, and is shipping free?
We dispatch within 24 hours from Pune, and shipping is free on orders above ₹500. A portion of every order supports Nanhi Kali girl-child education.
How do I contact SOSA support?
By email. We are a small Indian fragrance house, so a real person reads and answers - which, honestly, is worth more than a warranty badge nobody stands behind.
