Sizes, prices and value
The Hotel Collection comes in three sizes so you can try before you commit and then size up to the ones you love. Buying direct means the price is honest and the person who composed the fragrance stands behind the bottle.
| Size | Price | Best for |
|---|---|---|
| 15ml | ₹299 | Trying a new scent before committing |
| 100ml | ₹999 | The everyday value bottle |
| 300ml | ₹1799 | Best value per ml for daily diffusing |
A few drops perfume a whole room, so even the 15ml lasts many fills. The classic approach is to buy a couple of 15ml bottles to find your favourites, then size up to the 300ml of the scent you reach for every day.
There are seven scents to choose from, each our own interpretation of a famous hotel's signature style - from a Ritz-Carlton-inspired white tea and cedar to a W Hotels-inspired citrus, pepper and amber. They are inspired interpretations, not the hotels' actual scents, and SOSA is not affiliated with the hotels named.
Why water-based, not raw oils
When people search for "premium diffuser oils" they sometimes picture bottles of neat essential oil. For an ultrasonic diffuser, that is exactly what you do not want - and this is the most important thing I can tell you before you buy.
Myth: "Pure essential oil is the premium choice for any diffuser." Not for an ultrasonic one. Raw essential and carrier oils are too thick or solvent-heavy for the plate and can clog and damage it. The premium choice here is a well-composed water-based fragrance.
So the honest guidance is this: for a SOSA ultrasonic diffuser, buy SOSA's water-based Hotel Collection and use only that. A few drops in the tank with filtered water, and the whole room carries the scent - cleanly, and without shortening the life of your unit.
Direct means fresh and backed. Buying refills from sosahomeandbody.com means they come straight from the maker, dispatched within 24 hours, with us behind them if anything is not right - no reseller in the middle.

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.
