SOSA · The Founder Diaries · Hyderabad Homes
Three rooms, three scents,
one notebook
Once a home has more than one diffuser, the fragrance is rarely the problem. The problem is remembering which oil went where, how fast each room uses it, and what to reorder.
Nobody can tell you how long a bottle will last in your home. Your own home can, in about a month, if you write down four numbers.
Part of the SOSA guides for Hyderabad homes. Both machines take the same SOSA waterless oils.
The answer in 30 seconds
What does a home with several zones need?
- One line for each device. Room, machine, oil, date filled and amount.वायु Vaayu
- Measure. Do not estimate. Note the level again after a fortnight, and after a month.पवन Pawan
- Label everything. The bottle, and the room it belongs to.
- Buy only oils made for these machines. One compatible range serves both.
Why I will not give you a number
The question I am asked more than any other after a sale is how long the oil will last. I understand why. I also know that any single figure would be wrong for most of the people who read it. A living room run for two short windows a day uses a fraction of what the same machine uses in a room run all evening at a higher setting. The room, the hours and the setting decide it, and those are yours.
What I can give you is a method that takes five minutes and produces your own answer. It matters more as a home adds zones. One device you can keep in your head. Three devices in three rooms with three oils, refilled on different days, become guesswork within a season, and guesswork ends with the wrong oil in the wrong machine or an empty tank on the day guests arrive.
The arithmetic is plain. The oil a room has used, divided by the days it took, is that room's daily use at that setting. Divide a refill by the daily use and you have the number of days a refill will last there. Change the schedule or the setting and the figure changes, so measure again.
| The log, one line for each device | |
|---|---|
| Room | Living and dining, master bedroom, study. One line each. |
| Machine | Vaayu or Pawan. They take the same oils but hold different amounts. |
| Oil | The exact scent name, as printed on the bottle. |
| Filled | The date, and how much went in. Vaayu has a 400 ml refillable tank. Pawan takes its oil bottle directly. |
| Checked | The level after two weeks and after a month. The difference is what the room used. |
| Schedule | The hours and the setting during that period. Without these, the number means nothing. |
Different scents in different rooms
Different rooms with different fragrances is a pleasure, and it is how most of the homes I advise end up: something clean in the living space, something calmer in the bedroom, perhaps a third in the study. Two cautions. Keep neighbouring open rooms on the same scent or on closely related ones, because two fragrances meeting in a doorway rarely flatter each other. And when you change the oil in a machine, follow the changeover steps in its manual, so the old scent does not linger in the new.
The oils themselves are simple. Pawan and Vaayu both take SOSA waterless oils, sold as refills in 100 g and 300 g. They do not take water, ultrasonic diffuser oils, reed diffuser oils or thick essential oils, any of which can clog the nozzle. Skin perfumes and attars are a different product again and do not belong in either machine.
“One device you can keep in your head. Three devices in three rooms become guesswork within a season.”
A month of measuring
- Write one line for each device on the day you fill it. A notebook or a note on your phone will do.
- Label each bottle with its room. Especially spare bottles in a cupboard.
- Run your normal schedule. Do not change the settings during the month, or the measurement is lost.
- Check the level after two weeks, and again after a month. Write both down.
- Work out the daily use for each room. Oil used, divided by days.
- Reorder on those figures. Choose the refill size that suits how quickly each room uses oil, and order before the tank is empty.
वायु and पवन · one oil range for both

वायु Vaayu: a 400 ml refillable tank, and four 100 ml SOSA waterless oils in the set you choose when you buy it. Published for up to 1,000 m³ of a suitable connected zone.
पवन Pawan: 200 ml of oil included, as two 100 ml bottles in the two scents you choose. Published for one suitable room up to about 500 sq ft.

This applies equally to a villa with a device on more than one floor, a sky residence with a social zone and two bedrooms, and an apartment with a living room and a study. The formats differ. The notebook is the same.
