Choosing the Right CO₂ Cylinder for Your Soda Maker

October 4, 20261 min read

Screw-In CO₂ Cylinders

All Aqualine soda makers use Screw-In CO₂ cylinders. This is the correct cylinder type for Aqualine machines and is designed for easy installation and regular home carbonation.

If you own an Aqualine soda maker, always choose the Screw-In option when purchasing or requesting a refill.

Quick Connect CO₂ Cylinders

Quick Connect cylinders are designed for other compatible soda makers that use the Quick Connect system.

Because Screw-In and Quick Connect cylinders use different connection systems, always check your machine before ordering.

Aqualine CO₂ Cylinders

Aqualine CO₂ cylinders are:

Filled with food-grade CO₂
Designed for reliable sparkling performance
Suitable for everyday sparkling drinks at home
Available in different connection types for compatible machines

Check Before You Order

Before purchasing a new cylinder or requesting a refill, confirm whether your soda maker uses Screw-In or Quick Connect.

Choosing the correct cylinder helps prevent ordering mistakes and keeps your sparkling drink routine running smoothly.

If your sparkling water feels less fizzy than usual, your CO₂ cylinder may be running low. A weak or nearly empty cylinder can make carbonation slower and leave your drinks flatter than expected.

Running out of CO₂ can interrupt your sparkling routine, especially if you use your soda maker every day. A simple way to avoid this is to keep enough cylinders at home so you always have a backup ready.
