One Signature Scent or Different Fragrances for Every Room?
SOSA · choosing a scent
One signature scent, or a scent for every room?
Great hotels use one scent to say who they are. A home is different: the living room greets guests, but a bedroom belongs to the person who sleeps in it.

The short answer
Use one signature scent for connected spaces, so the house feels consistent as you walk through it. Let closed private rooms have their own scent, or none, chosen by the person who uses them. Each machine holds one oil at a time, so a different scent means a different machine or a change of oil when one runs out.
Decide together
Five steps
- Ask the household. Which scents does each person love, and which do they dislike?
- Shared spaces share a scent. Living, dining and connected corridors work best with one fragrance.
- Private rooms choose. A closed bedroom or study can have its own scent, or stay unscented.
- Choose from what we make. Woods and vetiver, or one of our hotel-inspired styles. Pawan has two pairs; Vaayu has four sets.
- Start low. Begin on a low setting and adjust after a few days.
Changing scents
How a change works
Each machine runs one oil at a time. Finish the oil, then refill with the next scent. Vaayu’s four oils in the box make it easy to change the mood by season.
Pawan or Vaayu?
Choose by the space, not the label
A flat size or a room name is only a starting point. Layout, ceiling height, airflow and closed doors decide what a space really needs.
Pawan: one room
One room of up to about 500 sq ft: a bedroom, study, cabin or small living room. It plugs into the wall, runs silently and is set from the SOSA app.
Vaayu: a connected space
One open, connected space of up to 1000 m³, roughly 2,000 to 3,000 sq ft depending on ceiling height. It schedules by day, run window and intensity.
Closed doors count
A room you keep closed is its own space. One Vaayu will not reach behind a shut bedroom door, so a closed room usually needs its own Pawan.

Questions
Before you choose
Should every room have the same scent?
It does not have to. One scent across connected spaces feels calm and consistent. A closed bedroom can have its own scent if the person using it prefers something different.
Can one machine switch scents on its own?
No. Each machine runs the oil you put in it. Change the oil when one runs out.
Can one room be left unscented?
Yes. Fragrance is optional. Simply leave that room without a machine, or switch a Pawan off in the SOSA app.
Which oils can I use?
Only SOSA waterless oils. Ultrasonic diffuser oils, reed diffuser oils and thick essential oils can clog the nozzle.
