· [Canister Compatibility] We don't mind if you call it a canister, cylinder, tank, or cartridge! But remember that our pink capped, Easy Connect canisters are compatible with all SodaStream Quick Connect soda makers including ART, TERRA and Duo. If you own a soda maker which requires a 'screw-in' canister, you will need to purchase our green capped, Threaded canisters.· [Sustainable & Eco-Friendly] At Soda Sense, we're proud to source 100% of our CO2 sustainably right here in the USA, and each of our 60L canisters replaces the use of over 170 single-use plastic bottles.· [Sparkling Water Made Effortless] Never run out of bubbles with Soda Sense & carbonate up to 60 liters of water with each of our canisters.· [Return & Recycle] All of our CO2 canister orders include a return box and shipping label to exchange your empty canisters when your done with them.
