Can One Fragrance Machine Suit a Duplex Home?
SOSA · duplex homes
One machine for a duplex? Plan each floor first
A duplex looks like one home but behaves like two floors. Scent rises and drifts, but not reliably up a staircase and behind bedroom doors.

The short answer
Usually not one machine for the whole duplex. Plan each floor as its own zone. A Vaayu on the main living floor can scent that connected area. The upper floor, with its bedrooms, usually needs its own plan: Pawan in closed bedrooms, or a second Vaayu for a large upper lounge.
Plan it
Six steps for a duplex
- Each floor is a start. Measure each floor’s connected living space separately.
- The staircase. An open, double-height staircase joins the floors more than an enclosed one, but still does not carry scent evenly.
- Downstairs is not upstairs. A machine that scents the living floor well will not reliably reach the bedrooms above.
- Living areas and bedrooms. Vaayu for a large connected living area. Pawan for each closed bedroom.
- Controls on each level. Set each machine for the hours that floor is used.
- What to send us. Each floor’s area and ceiling height, the staircase layout and which doors stay closed.
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 both floors?
Not reliably. It scents the connected space it sits in. Plan the upper floor separately.
Should I choose Pawan or Vaayu?
Pawan suits one room of up to about 500 sq ft. Vaayu suits one connected space of up to 1000 m³, roughly 2,000 to 3,000 sq ft depending on ceiling height. A room kept behind a closed door usually needs its own Pawan.
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.
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.
