  • Use only one charger at a time.


  • To clean, press the lever until the device is completely empty and depressurized. Remove the siphon head and rinse the components with clean drinking water only.

  • Rated 5 out of 5 by from Excellent Soda Siphon The instructions could be better- much better. What a year has taught me. 1-After refilling the siphon but before charging it, shake it for a good 20 seconds & then give the handle a squeeze or two. You will hear a release of gas - residual CO2 that can cause leaks. 2-Carefully screw the top on making sure it does not cross thread. 3-Before charging a new bottle, work the handle a couple of times. 4-Use COLD WATER. It charges better. 5-Make sure the sealing straw is seated well before putting the top on. 6-Leland Mr Fizz Seltzer Chargers are much less expensive than the ISI brand and work just as well. The shaking of the closed siphon and release of gas BEFORE charging the siphon was a game changer for me. I was having problems with leaks and it was just residual gas bubbles from a previous cycle.

    Rated 1 out of 5 by from No Longer Working After Six Months I received this soda siphon as a gift in June of 2015. I found it worked well until January of 2016. Now, the compressed carbon dioxide shoots out of the sides of the cap. It's unusable, and I am very disappointed.
