Most apartments need
less than they are sold
A three or four bedroom apartment is not a small villa. It is one connected living space and a handful of closed doors, and the commonest mistake is to buy for the square footage on the agreement.
Count the rooms whose doors stay open through the day. That is the space you are scenting. Everything behind a closed door is a separate, smaller question.

The answer in 30 seconds
What does an apartment need?
- Measure the living and dining room first. If it is one room of up to about 500 sq ft, a room device may be all it needs.पवन Pawan
- Step up only for a large connected run. Living, dining and corridor opening into one another, beyond what one room device is published for.वायु Vaayu
- A closed bedroom is a second purchase, not part of the first. Add it later if you find you want it.
- Ignore the saleable area. It includes walls, balconies and a share of a lobby you will never scent.
Through a closed door, nothing
The question I hear most from apartment owners is whether one diffuser in the living room will scent the bedrooms too. Through an open door, a little. Through a closed one, no. This is not a weakness of any machine. A closed door is what keeps cooking smells out of your wardrobe, and it keeps fragrance out by the same rule.
Once you accept that, an apartment becomes simple to plan. There is the space you keep open, usually the living and dining room and the passage off it, and there are the rooms you keep shut. Most of the pleasure of a fragranced home comes from the first. You walk in, and the room you live in smells the way you chose. The bedrooms can wait.
The second mistake is the opposite of the first: assuming a premium apartment needs the largest machine because the apartment was expensive. Price is not volume. A living and dining room of ordinary ceiling height is often within what one room device is published for. I would sooner you bought the smaller machine and were pleased than the larger one and found it too much.
| Which apartment is yours? | |
|---|---|
| One living and dining room | Measure internal length by width. A single room of up to about 500 sq ft is what पवन Pawan is published for. |
| A large connected run | Living, dining, family lounge and corridor open to one another. Work out the volume in cubic metres and assess वायु Vaayu. |
| An open kitchen | Part of the same air. Deal with cooking through extraction and ventilation first, and keep the diffuser at the far end from the hob. |
| Bedrooms | Each a separate room when shut. One room device each, and only where wanted. |
| Balconies | Not indoors. Leave them out of the plan. |
| Saleable and carpet area | Neither is the sizing input. Use the internal dimensions of the rooms themselves. |

Starting small is not a compromise
Begin with the room you spend your evenings in. Live with it for a fortnight. If the scent reaches as far as you want, you are finished. If the living space is larger than one room device can hold evenly, you will know, and the step up to a zone device becomes a decision made on evidence.
Both machines take the same SOSA waterless oils, so nothing you bought first is wasted if you add to it.
“Price is not volume. Buy for the rooms you keep open, not for the number on the sale agreement.”
Setting it up
- Leave your doors as you normally keep them and walk the flat. Note which rooms are open to the living space and which are not.
- Measure the open living space. Internal dimensions only.
- Choose by that measurement. Not by the number of bedrooms and not by the size of the apartment.
- Keep the device away from the kitchen end and the balcony door. Both carry fragrance off before it settles.
- Set short windows. One before you wake and one before you are usually home is enough for most households.
- Decide about bedrooms after two weeks. Not before.
