Which diffuser? The 6L Megh - a living room is large and open, so it needs a big tank and reach to fill evenly.
The secret? Restraint. Luxury reads as a scent you notice on arrival and then forget, not one that fills the room.
The lobby hush, at home
Think of the last hotel lobby that felt truly expensive. The scent was probably clean and soft - white tea, a little cedar, a whisper of citrus - and you could not quite place it because it was pitched so low. That restraint is the whole trick. Luxury scent is confident enough to whisper.
For a living room I reach for Quiet Luxury, my interpretation of that Ritz-Carlton-style white tea, bergamot and cedar, or Warm Welcome for something warmer and more hospitable with its citrus, floral and sandalwood. Both are clean and grown-up, and both flatter a room without dominating it.
The luxury is in the level, not the litres. A soft, even haze of a clean scent reads as far more expensive than a room drenched in fragrance, however nice the fragrance is. When in doubt, dial it down.
Honesty matters here: Quiet Luxury and the rest are my own interpretations of the styles famous hotels are known for, not the hotels' actual scents, and SOSA is not affiliated with them. The names just tell you the character to expect.
Scaling it to a living room
A living room is the one room where a small diffuser lets you down, because there is simply too much air to scent. The lobby hush only works if the mist actually reaches the far side of the room - and that takes a big tank.
Myth: "Luxury means a discreet little diffuser tucked on a shelf." In a small room, yes. In a large, open living room, a small unit cannot carry the scent - and a room you can only smell from one chair does not feel luxurious at all.
The Megh solves the scale problem: a 6-litre tank, an adjustable mist dial to set the level, quiet running around 35 decibels, and up to 100 hours per fill. Run it low-to-moderate, placed central and raised near gentle airflow but away from the direct AC blast, and the lobby hush spreads evenly across the whole room. In dry AC or winter air it humidifies while it scents, too.
Keep it clean, keep it luxurious. Use the water-based Hotel Collection fragrance only, with filtered water at room temperature. Raw essential and carrier oils are thick and can clog the misting plate; a few drops of ours holds a soft, even scent across the room.
So a luxury living-room scent is the lobby hush - Quiet Luxury or Warm Welcome - run softly through a big-tank Megh sized to the space. Restraint on the dial, filtered water, SOSA water-based fragrance only, and your living room carries the calm of a lobby you would happily linger in.

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.
