A Fragrance-Zoning Plan for Multilevel Row-House Interiors
SOSA · for interior designers
Zone the scent floor by floor
A zone schedule turns “make the house smell lovely” into a plan a client can approve and a site team can install.

The short answer
Create a zone schedule. List each connected indoor zone with its area and ceiling height, mark doors and air connections between levels, note which rooms are scented and which are not, then assign Pawan or Vaayu to each zone. Quantities stay conditional until checked in the finished space.
The schedule
Six columns
- Zone. Each connected space on each level: living-dining, family lounge, each bedroom, study.
- Volume. Floor area times ceiling height. Never divide total house area by a headline coverage figure.
- Connections. Open stairs, double-height voids and doors, and whether they stay open.
- Scented or not. The client’s choice for each zone.
- Device. Pawan up to about 500 sq ft, Vaayu up to 1000 m³, or none.
- Placement and oil. Location, power, chosen scent and starting setting.
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
Will one Vaayu scent every floor?
No. Vaayu scents the connected space it sits in, up to 1000 m³. Each floor, and each room kept behind a closed door, is planned on its own.
Can I size by total built-up area?
No. Size each connected zone by its own volume and doors.
What should I send you for a recommendation?
A floor plan or rough sketch, the size of each room or zone, ceiling height, which doors stay closed, where the sockets are, the hours the space is used and the scents you like. Photos help too.
What does each machine need?
Pawan plugs straight into a wall socket. Vaayu runs from its power adapter and can stand on a shelf, mount on a wall or fit on an HVAC return. Both need to be reachable for refills.
