How to Set Up, Maintain and Measure Oil Use in a Waterless Diffuser
SOSA · set-up and care
Set up, look after and measure your oil
How long oil lasts depends on your space, your settings and your hours. The best way to know is to measure it in your own room.

The short answer
Follow the set-up guide in the box for your machine, start on a low setting, and keep a simple log: the setting, the hours it runs and how much oil is left each week. After a few weeks you will know how fast your space uses oil. If the scent seems weak, check the setting, placement and airflow before assuming you need a refill.
Set it up
The first day
- Follow your model’s guide. Pawan plugs into the wall and pairs with the SOSA app. Vaayu pairs over Bluetooth or uses its buttons. Use the guide that came in the box.
- Start low. Begin on the lowest setting with short run windows, then adjust after a few days.
- Place it well. Away from an AC blowing straight at it, and where air moves gently through the space.
Measure it
Keep a simple log
- Write down the basics. The machine, the setting, the run window, the days and the room.
- Measure the same way each time. Weigh the bottle on a kitchen scale, or mark the level, once a week. Use the same unit throughout.
- Work it out. After three or four weeks, you will see how much your space uses per week at your settings.
Care
Looking after it
Finish one oil before switching to another. If the scent seems weak, check the setting, the run window and whether a door or AC is pulling the scent away before topping up.
A business running all day at high intensity will use oil much faster than a home. Use your own log, not a home estimate, to plan refills.

Before you choose
Which oils can I use?
Only SOSA waterless oils. Ultrasonic diffuser oils, reed diffuser oils and thick essential oils can clog the nozzle.
How long does Vaayu’s oil last?
About a year on typical home scheduling, a few hours in the morning and evening at medium. All-day, high-intensity use in a business uses it faster.
Why does the scent seem weak?
Check the setting, the run window, the placement and any strong airflow first. Your nose also gets used to a scent over time.
Can I schedule them?
Yes. Pawan is set from the SOSA app with a timer, for example mornings and evenings. Vaayu is set from the SOSA app over Bluetooth or its buttons: the days, a run window of 1, 4, 8 or 24 hours, and the intensity.
