This patented Surge Infuser cap is the key component of the Surge soda maker and it's advisable to have a spare. It's exactly like the original one that came with your Surge and fits all Surge bottles.
Why having a spare infuser cap is useful:
- when your main infuser cap is in use, or being washed
- when you want to make and store different drinks
- if your main infuser cap gets lost or damaged
