The doors you open
decide the room you scent
In a duplex with a terrace, one level usually lives with its doors open and the other with them shut. Fragrance belongs on the level, and in the hours, that hold their air.
Do not fight an open terrace door. Note when it is open, scent the hours and the rooms when it is not, and stand the source where a draught cannot reach it.

One of the SOSA guides for Hyderabad homes. Start with whether the two levels of a duplex share air.
The answer in 30 seconds
Fragrance and an open terrace
- Write down when the doors are open. Three days is enough to see the pattern.
- Scent the level, and the hours, that stay closed. Set the timer around your own habit.वायु Vaayu
- Keep the source indoors, away from the opening. Out of the draught and out of any damp.
- A closed bedroom is unaffected. Give it a room device of its own.पवन Pawan
A door pattern, not a setting
When owners tell me their living room loses its fragrance, I ask one question before any other: when are the terrace doors open? The answers fall into patterns. Some households open them at sunrise and shut them when the day heats up. Some open them at dusk and leave them until bed. A few never close them at all. Each is a different home to fragrance, and no setting on a machine turns one into another.
With the doors open, the room is exchanging its air with outdoors, and fragrance goes with it. With them shut, the same room holds scent well. So the plan follows the pattern. If the doors are open in the evening, run the living space earlier and let it finish before they open. If they are open in the morning, run it after they close. The timer is what makes this effortless: you set the windows around your own habit and stop thinking about it.
A duplex gives you a second choice that an ordinary flat does not. If the terrace opens off one level, the other level is unaffected by it, provided the two are not joined by an open void. Many families find that the level without the terrace becomes the fragranced one, and the terrace level is simply left to the breeze.
Keep the device itself indoors and dry. A source standing beside an open door is exposed to whatever blows in. Treat both machines as indoor devices.
| Reading your own pattern | |
|---|---|
| Open in the morning | Run the living space after the doors close, and again in the evening. |
| Open at dusk | Run it in the afternoon, and let the window end before the doors open. |
| Open all day | Do not scent that room. Choose a room or a level that stays closed. |
| The other level | Unaffected, if a ceiling or a door separates the two. A good home for the main fragrance. |
| Bedrooms | One closed room each. पवन Pawan is published for one suitable room up to about 500 sq ft. |
“No setting on a machine turns an open room into a closed one. Set the hours around your doors.”
For your interior designer: beside an indoor-outdoor lounge
A lounge that opens to a terrace is the hardest room in a home to give a scent point, and the one where it is most often put in the wrong place.
- Ask the client when the doors are open. Mark it on the plan.
- Mark the draught through the room when they are. Door to door, or door to window.
- Put the scent point on the inner side. At an indoor socket, out of that line.
- Keep the device within its rated environment. Indoors, dry and protected from rain and spray.
- Separate the lounge from the closed rooms. Different devices, different timers.
