Can One Diffuser Scent a Two- or Three-Storey Row House?
SOSA · multi-storey homes
Upstairs and downstairs: one machine or more?
A row house stacks its life on two or three floors: living and dining below, bedrooms above, sometimes a terrace room at the top. Scent does not climb a staircase evenly.

The short answer
Usually not one machine. Plan each floor as its own zone. A Vaayu can scent the connected living floor if it fits within 1000 m³; upstairs, a Pawan in each closed bedroom that wants fragrance. An open, double-height stair joins floors a little, but it does not carry scent reliably into rooms above.
How floors behave
Why the stair is not a duct
- Each floor is a zone. Measure the connected space on each floor separately: area times ceiling height.
- Open stairs help a little. A double-height or open stair joins floors, but scent thins as it rises and spreads.
- Closed rooms are separate. A bedroom with its door shut is its own space, whichever floor it is on.
- Decide which floors matter. Many owners want only the living floor and one bedroom scented. Start there.
- Add only where wanted. A Pawan for each closed room someone wants scented. Nothing for rooms that should stay unscented.
A worked example
An illustrative G+2 plan
Ground floor: an open living and dining space with a 10 ft ceiling. One Vaayu, if the connected volume fits its range. First floor: two bedrooms with doors usually closed, one Pawan each if both want it. Second floor: a study, one Pawan. This is an illustration only, not a plan for any particular home.
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.
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.
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.
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.
