Using a SodaStream system to turn tap water into sparkling water is an easy and economical way to create refreshing, fizzy beverages at home. But eventually the carbonator that comes with your system will run out of gas.

When this happens, all you need to do is bring your empty carbonator to a Best Buy store and exchange it for a new one ─ at a less expensive price than buying a brand new carbonator.

Of course, if you want to have a spare carbonator on hand, we sell those too. Shop for both exchange and spare carbonators below. Remember, you can order these carbonators online, but we aren't able to ship them, so you must choose store pickup when you check out.
