How Do I Plan Fragrance for a Larger 4BHK?
SOSA · 4BHK homes
Fragrance for a larger 4BHK, zone by zone
In a large home, the number of bedrooms says little. What matters is how much air is connected, how far the rooms are from each other and which doors stay closed.

The short answer
Plan by zone, not bedroom count. One Vaayu can scent a connected living area within 1000 m³. A long corridor, a second living area or a distant wing may need its own machine. Closed bedrooms each need a Pawan if you want them scented. For a large or unusual layout, send us the floor plan.
Plan it
Six steps for a 4BHK
- Floor area is not air volume. A double-height living room or high ceilings hold much more air. Measure height as well as area.
- Distant rooms and corridors. A long enclosed corridor or separate wing behaves as its own space.
- Different preferences. Parents, children and guests may want different scents, or none.
- Choose by zone. Vaayu for each large connected area, Pawan for each closed room that wants it.
- Plan refill access. Place machines where you can reach them easily to refill and adjust.
- Know when to ask. Very large floors or central AC need a floor-plan review. We also make larger HVAC systems.
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 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.
What if the space is larger than Vaayu’s range?
Split it into zones and plan each one, or ask us about our larger HVAC scenting systems for big floors or central AC.
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.
