Do I need to buy fragrance separately? No - three water-based fragrances come in the box, so you can use it the first evening. Refills start at ₹299 (15ml) when you want more scents.
What must I never put in it? Use only SOSA's water-based Hotel Collection fragrance in an ultrasonic diffuser - raw essential oils, perfumes and carrier oils are too thick or solvent-heavy and can clog the misting plate and damage the unit. Use SOSA water-based Hotel Collection fragrance only, with clean room-temperature water.
What ₹799 gets you
Let me lay out the Boond plainly, because the number that matters most under ₹1000 is tank size, and this is where cheap units fail. The Boond holds 300ml. That runs up to 6 hours of cool mist - long enough to cover an evening or a full working session at a desk.
Around that tank you get USB power - handy for a work desk, a hostel room or a bedside off a power bank - a soft colour night light that doubles as a gentle glow at night, coverage of roughly 150 sq ft, and that auto shut-off. It is compact and quiet by design. And crucially, three of our water-based Hotel Collection fragrances come included, each my own interpretation of a famous hotel's scent style. These are inspired interpretations, not the hotels' actual proprietary scents, and SOSA is not affiliated with the hotels named.
Who the Boond is for
The Boond is built for smaller spaces: a work desk, a bedside table, a study, a hostel or PG room, a home cabin. At ~150 sq ft it will not fill a large living room - if that is your room, look at the Sukoon (500ml) or Megh (6L) instead. But for personal, close-range scent, it is exactly right, and the USB power makes it the most portable of the three.
Reality: Use only SOSA's water-based Hotel Collection fragrance in an ultrasonic diffuser - raw essential oils, perfumes and carrier oils are too thick or solvent-heavy and can clog the misting plate and damage the unit. The Boond ships with the right water-based fragrance included, so the budget route is actually the safe route here. Use clean, room-temperature water - filtered or RO in hard-water cities - and never hot water. Remember scent is not air purification; it is cool mist that carries fragrance.

Versailles
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.
