How many canisters can I send for exchange at a time? 

Understanding how many CO2 canisters you can send for exchange at a time is crucial for maintaining a steady supply of sparkling water. Here’s what you need to know: 

• We accept 2 canisters for exchange at a time. 

• Our Refill Box is specifically designed to securely hold 2 canisters, ensuring they reach us safely. 

• Although we refill 2 canisters at a time, we recommend having 3 canisters in circulation. 

Why Keep 3 Canisters? 

Keeping three canisters ensures that you always have a spare canister ready while the others are being refilled. This cycle provides a seamless experience without any interruptions in your supply of sparkling water.
