How does the CO2 Refill Club work?

Our CO2 Refill Club allows you to save 30% on CO2 by only paying for the refill on future exchanges.

  1. Your canisters will arrive in a CO2 refill box with a shipping label for free returns so there is no need to order a separate box.
  2. Hold onto the refill box until (2) CO2 canisters are empty.
  3. Package up your (2) empties, attach the shipping label and mail the box to us via USPS. We’ll automatically send you (2) new canisters for $41.99 plus tax when we receive your empties.
What if I have lost the refill box or label?
You can purchase a CO2 Refill Box and shipping label here.
