Differences between SodaStream Fizzi and Source

The first obvious difference is in their designs and size. The Fizzi has a more rounded design while the Source is angular and boxy. The Source is also significantly bulkier than the Fizzi. Moreover, Fizzi comes in more colors other than white and black. Although both soda makers do not let you set the level of fizziness, only the Source has an LED indicator for fizziness. Lastly, the Source only comes with a mini CO2 cylinder that can make up to 9 liters of soda water. But you can use the free 60-liter mail-in rebate to get yourself a 60-liter CO2 cylinder.

SodaStream Fizzi and Source Review

The SodaStream Fizzi and Source share a lot of similarities. Let’s expound on each of their similarities.

CO2 Cylinder Compatibility

Both the Fizzi and Source both come from SodaStream, it is only logical that both soda machines are compatible with the same CO2 cylinders. These sparkling water makers are compatible with both the 60-liter and 9-liter CO2 cylinders. Its Gas Exchange Program is what separates SodaStream from its competition. The price you need to pay for a full refill for a 60-liter tank is only $15 which is unmatched. If you need an extra CO2 cylinder, you can purchase a spare cylinder for only $30 which is also the cheapest you can find.

Manual Pump Action 

SodaStream Fizzi and Source, unfortunately, are not automatic soda machines. One great advantage, however, is the fact that both sparkling water makers do not need electricity or a battery to power up. However, you should take note that the Source has a non-user-replaceable battery that powers the LED indicators in front. This is one of the disadvantages of the SodaStream Source, once the battery dies out, its LED fizz indicator will no longer work.

Soda Water and Specialty Drinks

Aside from making sparkling water using these machines, you can also create other specialty drinks. You can flavor up the bland soda water using the fruit drops that SodaStream is also selling. There are also soda flavors you can try that contain less sugar than your regular store-bought sodas. Moreover, you can also create carbonated cocktails with the recipes you find on SodaStream’s website. If you are not a fan of alcoholic beverages, you can also find other recipes there such as infusions and mocktails. Buying a sparkling water maker gives you full control of the ingredients you want to consume.

SodaStream Source


  • Overall, the SodaStream Source has a better design language and can look better with other appliances on your kitchen countertop.
  • It has an LED fizz indicator, so you won’t have to guess the amount of carbonation you are putting in your drink.
  • You get an extra 9-liters of sparkling water you can make with its mini CO2 cylinder.
  • Since the Source uses a manual pump action to carbonate water, it does not need electricity or batteries.

Final Verdict

Since these soda machines share a lot of similarities, it makes you wonder why the other one is significantly more expensive. What does the SodaStream Source have that the Fizzi does not have? How come these machines have a huge price difference? The SodaStream Source is so expensive because it is designed by a famous designer. The Source has an undoubtedly better design, don’t get me wrong. But it does not make sense to me that its price tripled even if both machines function identically. One advantage it has, however, is the LED fizz indicator. However, it also acts as one of its disadvantages since it is powered by a non-user-replaceable battery. With all of that said, I strongly recommend you get the SodaStream Fizzi over the Source. But if you truly care about the design and the LED fizz indicator, by all means, buy the SodaStream Source.
