Exchange any brand's canisters
We committed to making the use of soda makers sustainable by minimizing the need for producing new canisters. That's why we exchange 60L canisters from any brand.
An automated refill process
After setting up an account, members no longer need to log on to the website for refills. Simply box up empty canisters and when USPS scans the pre-paid label, we send out 2 full canisters.
On-demand CO2 refills
Only get CO2 when you need it; we'll send canisters when you send us empties! There are no maximum refills, forced return windows, or late fees.

Saves me so much time
Soda Sense saves me so much time. I used to hate going to the store to exchange my canisters. Now I put the empty ones in the mail and get new ones shipped!

Perfect product, we love it
Since we found Soda Sense, we can now send our refills in the mail, and get it back in 2-3 days. We're so happy that we found Soda Sense!
@Linda C
Soda Sense rocks
What I love most about Soda Sense is that they took the empty canisters I already had from another brand and refill them through the Refill Club.
