Using CO₂ with your iGulu F1 gives you better carbonation, smoother dispensing, and longer storage for your finished brews. This guide explains whether CO₂ is required, which cylinders are compatible, how to install CO₂ safely, and how to troubleshoot common issues.

1. Is a CO₂ cylinder required to use the machine?

No — CO₂ is optional.
The iGulu F1 includes a built-in air pump, which allows you to dispense your drink without CO₂.

When using air pump only:

• Suitable for tasting or short-term drinking

• Best consumed within 24 hours, as air shortens freshness

When using CO₂:

• Provides proper carbonation

• Allows smoother dispensing

• Extends storage up to 30 days in COOL mode

2. What type of CO₂ cylinder should I purchase?

The CO₂ adapter on the back of the F1 machine supports cylinders with a TR21*4 thread, such as the blue screw-in type SodaStream bottles.
