How long before guests should I turn on the diffuser? About 30 to 45 minutes ahead. That gives the scent time to spread and settle into the background, so it feels welcoming when guests walk in rather than fresh and sharp.
Why not switch the diffuser on as guests arrive? Because a freshly started mist is at its sharpest, and guests walk straight into it. A scent switched on 30 to 45 minutes earlier has settled into a soft, welcoming background.

Straight answer
Which fragrance should you switch on before guests arrive, and when?
Switch on a welcoming Hotel Collection fragrance (₹299) - Four Seasons-inspired citrus and sandalwood, or Ritz-Carlton-inspired white tea and cedar - about 30 to 45 minutes before guests arrive. In a Megh 6L (₹3,499) for a large space, that gives the scent time to settle so it feels welcoming, not fresh and sharp. It is water-based and non-toxic.
Switch on a welcoming hotel-inspired scent about 30 to 45 minutes before guests arrive, so it has settled into a soft, welcoming background by the time they walk in.
A safe, well-loved place to start is the SOSA Hotel Collection fragrance in a Westin-inspired white tea - clean, calm and universally liked, from ₹299, in a compact ultrasonic diffuser like the Boond (from ₹899). It is the simplest way to make a room smell like a five-star lobby.

How to time and choose the fragrance you switch on before guests arrive
Getting the pre-arrival scent right is about three things: choosing a welcoming profile, timing the switch-on so it settles, and sizing the diffuser so it has filled the room in time.
1
The right scent
Welcoming, not challenging
The pre-arrival scent should greet a mixed group. Four Seasons-inspired citrus or Ritz-Carlton-inspired white tea are welcoming to almost everyone - safe choices for a first impression.
Tip: choose a scent that greets everyone, not one that divides opinion.
2
The right timing
30 to 45 minutes ahead
A freshly started mist is sharpest at first. Switching on 30 to 45 minutes before guests arrive lets the scent spread and settle into a soft, welcoming background.
3
The right size
Big enough to fill the room in time
A larger space needs a bigger diffuser to be scented in 30 to 45 minutes. A Megh 6L fills an open floor; a Sukoon 500ml suits a smaller living room.
Tip: size the diffuser so the room is ready by the time the doorbell rings.
The SOSA principle
The best-hosted rooms are scented before anyone arrives - the welcome is already in the air by the time the first guest reaches the door.
Thirty to forty-five minutes is the small head start that makes it feel effortless.
Which hotel-inspired SOSA scent to switch on before guests
For the pre-arrival scent, keep it welcoming and universal - save any statement or warmer scent for later in the evening once the room has settled.
The SOSA scent edit
Which hotel-inspired scent to switch on first
| Scent | Why it suits the mood |
|---|---|
| Four Seasons-inspired citrus & sandalwood | Bright and welcoming - the ideal first impression as guests arrive. From Rs 299. |
| Ritz-Carlton-inspired white tea & cedar | A safe fresh-woody crowd-pleaser for a mixed group. From Rs 299. |
| Westin-inspired white tea & cedar | Clean and barely-there - the gentlest, most livable welcome. From Rs 299. |
For a large hosting space, the Megh 6L (₹3,499) fills the floor in time and runs for the whole evening; a Sukoon 500ml (₹1,899) is quicker to scent a smaller living room.

A note from Sonal
The reason a great hotel stays with you is often the smell the moment you walk in - clean, calm, quietly expensive. I built the Hotel Collection to bring that feeling home. Each of the seven fragrances is my own interpretation of a scent world I love, composed as a perfumer, and made water-based so it runs beautifully in an ultrasonic mist diffuser.
My advice is simple. Choose the diffuser by your room first - a small Boond for a bedside or compact space, the Sukoon for a bedroom or living room, the Megh for a big open hall, and the waterless Vaayu when you want a whole home to smell consistent. Then choose the scent by mood: fresh white-tea (Westin-inspired) for a clean, minimalist calm; woody cedar and vetiver (1 Hotels-inspired) for something grounded; warm amber and woods (St. Regis-inspired) for an evening, luxurious feel.
One honest note: raw undiluted oils clog ultrasonic units and can smell harsh, so I keep these water-based and non-toxic - safe to run for hours, kind to the people and pets in the room. Everything is made in small batches in India, and a part of every order supports girl-child education. That is the kind of thing I am proud to put my name on.
Frequently asked questions
How long before guests arrive should I switch on the diffuser?
About 30 to 45 minutes ahead. That lets the scent spread and settle into a soft, welcoming background, so it feels welcoming when guests walk in rather than fresh and sharp.
Which scent is best to switch on before guests arrive?
A welcoming Four Seasons-inspired citrus and sandalwood, or a classic Ritz-Carlton-inspired white tea and cedar - both greet a mixed group well and make a safe first impression.
Why not turn the diffuser on as guests walk in?
Because a freshly started mist is at its sharpest, and guests walk straight into it. Starting 30 to 45 minutes earlier gives a settled, welcoming scent instead.
Does the diffuser size affect the timing?
Yes - a larger space needs a bigger diffuser to be scented in 30 to 45 minutes. A Megh 6L (from Rs 3,499) fills an open floor in time; a Sukoon 500ml (from Rs 1,899) suits a smaller living room.
Is it safe to leave the diffuser running once guests arrive?
Yes - SOSA Hotel Collection fragrances are water-based and non-toxic, made for ultrasonic mist diffusers, so they are safe to run for hours through the evening. Top up the water as needed.
