How to Plan Refills for a Fragrance Machine Used Every Day
SOSA · refills
Plan refills before you run out
A machine used every day needs oil on hand. How fast it goes depends on the space, the setting and the hours it runs.

The short answer
Use only SOSA waterless oils. Vaayu’s four 100 ML oils last about a year on typical home scheduling, a few hours in the morning and evening at medium. A salon or shop running it all day at high intensity will use them faster. Vaayu takes our 100 G and 300 G refills.
What changes how fast oil is used
Three settings matter most
- Hours. All day uses far more than a morning and evening block.
- Intensity. High uses more than medium or low.
- Space. A business open all day uses more than a home.
A simple habit
Reorder when you open your last bottle
When you start the last bottle, order the next refill. For a business running all day, keep one refill in stock at all times. For Pawan, ask us which refill suits it before you order.

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 salon or shop uses it faster.
