What tank size do I need? Match it to the room - 300ml (Boond) for a desk or small room and a few hours per fill, 500ml (Sukoon) for a normal room and most of an evening, and 6L (Megh) for a large room or office running for days. A bigger tank means longer runtime and a larger space.
Can I use essential oils in a SOSA ultrasonic diffuser? Use SOSA water-based Hotel Collection fragrance, added a few drops to the water tank - raw essential and carrier oils are too thick for the ultrasonic misting plate and can clog it. The water-based fragrance mists cleanly and scents the whole room.

Straight answer
Which ultrasonic diffuser should I buy?
An ultrasonic diffuser turns water and a few drops of fragrance into a cool mist, and the main choice is tank size, because that decides runtime and how big a room it can scent. SOSA's three: the Boond (₹799, 300ml) - USB, a colour night light, made for a desk, bedside or small room, running a few hours per fill. The Sukoon (₹1799, 500ml) - a 7-colour mood light, remote and 2H/4H timers, made for a bedroom or living room, running most of an evening. The Megh (₹3499, 6L) - a whisper-quiet large tank that runs for days and scents a large room, open-plan space or office. All three are cool mist (no heat), have auto shut-off, and ship with three water-based Hotel Collection fragrances. The rule: pick the tank for the room - Boond for small and personal, Sukoon for a normal room, Megh for a big one. And use SOSA water-based fragrance only - raw essential or carrier oils are too thick and can clog the ultrasonic plate.
One line: pick by tank and room - Boond (300ml, desk), Sukoon (500ml, bedroom), Megh (6L, large rooms).
Match the diffuser to your room and budget - explore the SOSA diffuser range — reeds from ₹749, ultrasonic from ₹799.

Mood light, remote, timers, for a bedroom or living room. Runs most of an evening.

The SOSA principle
Match the diffuser to the room, not the hype.
A desk wants a small ultrasonic like Boond; a bedroom, the Sukoon; a large room or office, the Megh; anywhere you want always-on scent with no electricity, a reed diffuser; the car and travel, the Safar. Size and use decide it - then the fragrance does the rest.
Which SOSA diffuser to pick
SOSA makes three ultrasonic cool-mist diffusers, five alcohol-free reed diffusers, and the Safar travel diffuser - so there is a right one for every room and budget. Here is the match.
Our pick for this
Match the tank to the room: Boond (₹799) for a desk or small room, Sukoon (₹1799) for a bedroom or living room, Megh (₹3499) for a large room or office. All cool-mist, auto shut-off, and shipping with three hotel-inspired fragrances.
The SOSA diffuser line-up
Reed, ultrasonic and travel - which fits
| Diffuser | Best for |
|---|---|
| Boond (₹799, 300ml ultrasonic) | Cool mist + soft glow; desk, bedside, small rooms; under ₹1000 |
| Sukoon (₹1799, 500ml ultrasonic) | Light, remote, timers; bedroom and living room |
| Megh (₹3499, 6L ultrasonic) | Large tank, whisper-quiet; large rooms, offices, villas |
| Reed diffusers (from ₹749) | No electricity, alcohol-free, always-on soft scent; any room |
| SOSA Safar (₹3999) | Waterless, cordless, rechargeable; car and travel |
One honest note on the ultrasonic diffusers: they use SOSA’s water-based Hotel Collection fragrance, added a few drops to the water tank - raw essential or carrier oils are too thick and can clog the ultrasonic plate. Reed diffusers, by contrast, use their own alcohol-free reed oil and need no electricity at all.
The best diffuser is not the priciest - it is the one that fits your room.

A note from Sonal
I trained as a perfumer at ISIPCA in Versailles, but half the questions we get are about the machine, not the scent. So we built a range for real Indian rooms - Boond for a desk, Sukoon for a bedroom, Megh for a whole floor - each a cool-mist ultrasonic diffuser with no heat and an auto shut-off.
For anyone who wants scent with no electricity, our five reed diffusers are alcohol-free and last weeks; and for the car and travel, Safar is a waterless, cordless, rechargeable diffuser. Whatever the room, there is a right one.
One thing I always say about the ultrasonic diffusers: use SOSA’s water-based fragrance, not raw essential oils, which are too thick for the misting plate. A few drops in the tank scents the whole room cleanly.
