There are four easy ways to make carbonated water without using a CO2 tank;
- Using a Soda Siphon
- The Bonne O Appliance
- Dry Ice Method
- Vinegar and Baking Soda Method
1- Soda Siphons
Soda Siphons are one of the most popular ways to make sparkling water without using a CO2 tank.
They work using small CO2 cartridges also known as Charges, that you insert into the soda siphon which then releases the CO2 gas and thus carbonates the water.
Soda Siphons consist of;
- A Container that holds the water to be carbonated
- A Head that is screwed on to the container, the head is also where the CO2 cartridges are inserted, and thus responsible for releasing the CO2 to carbonate the water.
- CO2 cartridges contain CO2 which is added to water to carbonate it. One cartridge usually carbonates one container of water.
The soda siphon that I recommend is the Isi Soda Siphon.
I don’t own one of these but my parents have had one for ages and I have used it a lot of times.
Isi Soda Siphon
The Isi Soda Siphon is a classic soda siphon.
Its one of the most common Soda Siphons around, making CO2 cartridges that work with it much easier to find.
The Isi container is made of stainless steel and comes with a nozzle that sprays out carbonated water when the lever on the side of the head is pressed.
How the Isi Soda Siphon Works
The Isi has a simple set up, I found a really short video below to show the Isi in action.
Pros of A Soda Siphon
- Very Portable easy to carry around and plus really easy to store.
- Sleek design that goes really good with your kitchen and you won’t mind showing off at parties.
- Initial Cost is low the Isi is more affordable compared to any SodaStream appliance.
- Very Easy to Use and Set Up this is why my parents prefer Soda Siphons over SodaStream.
- Most Common Soda Siphon available this makes CO2 cartridges and information on the Isi easy to find.
Cons of the Soda Siphons
- the Cost for CO2 cartridges can add up over time, the SodaStream CO2 tanks tend to work out more cost effective over time.
- Soda Siphons don’t give the strong levels of carbonation like a SodaStream, you even have to roughly shake the Soda Siphon to make the water more carbonated.
Who Should Get a Soda Siphon
- If you intend to carbonate water on frequently think twice a day the Soda Siphon is probably not for you unless you are ok with extra cost.
- Now the Soda Siphon is perfect for those who want the occasional sparkling water think three or four times a week without the hassle of dealing with CO2 tanks.
- Soda Siphons are also the best way to make carbonated beverages on the go or outdoors think picnics or camping, also I have heard individuals even use them at the office.
Tips When Using the Isi Soda Siphon
- Only carbonate cold water, CO2 dissolves better in cold water.
- To make the water colder, my parents usually put their Isi in the freezer to store it even if its empty, this is to make the container extra cold so when the water is added it can carbonate much better.
- Once you have inserted the CO2 cartridges shake the Soda Siphon vigorously, this helps to increase the surface area of the water and makes the CO2 dissolve faster.
- After shaking let the water rest for 15 minutes in the fridge before drinking.
Where Can You Get An Isi Soda Siphon
Amazon usually has great deals on the Isi Soda Siphon, you can click to see the current price of the Isi on Amazon.
Also, don’t forget the CO2 cartridges you can click to check the price of a Packet of 10 cartridges on Amazon.
2- Bonne O
The Bonne O appliance is a new and innovative appliance that uses Carbonation tablets instead of CO2 tanks to carbonate water.
Bonne O is made and design by a Canadian company and thus regulated by the Canadian Government so I am confident the appliance is safe to use.
How it Works
The Bonne O uses Carbonation tablets which are made of citric acid, potassium bicarbonate, sodium bicarbonate (baking soda), and potassium carbonate.
All of which are food grade material.
Now the great part of the carbonation tablets is that they aren’t added directly to the water.
Which would alter the composition of the water with additives and I wouldn’t be writing about the Bonne O if that was the case.
Instead, the Carbonation tablets are added to a separate compartment and then when the machine is turned on the CO2 made from the carbonation tablets is transferred to the water making it carbonated.
You can See the Bonne O in action in the Short Video Below
Pros of the Bonne O
- The Cost for carbonation Tablets is roughly the same as exchanging SodaStream CO2 tanks and tend to be cheaper than CO2 cartridges used in a Soda Siphons.
- Can Carbonate any Beverage from Juices to Ice teas you are not limited to carbonating only water, unlike Soda Siphons and SodaStreams which limit you to only water.
- Bonne O appliance will consistently carbonate your beverage, unlike a Soda Siphon which needs some manual shaking up to carbonate.
Cons of the Bonne O
- The Initial Cost of the Bonne O is much higher than a budget SodaStream or most Soda Siphons.
- Requires electricity to function.
- Bonne O will take up more space than a Soda Siphon.
- Carbonation process takes a bit longer than a SodaStream around 3-4 minutes, but still faster than a Soda Siphon
Who Should Get a Bonne O
- If you and your family use or intend to consume sparkling water regularly and want to avoid bulky CO2 tanks then the Bonne O is a good alternative for you.
- If you want the ability to Carbonate any beverage, the Bonne O is the option for you.
- Imagine making your own carbonated Ice tea or carbonated Apple juice.
Where Can You Get the Bonne O
The Bonne O is available on Amazon who usually have great deals on these types of products, you can click to see the current price.
Make sure you buy lots of Carbonation tablets, you can click to see the current price on Amazon for a packet of 10.
Now when carbonation tablets run out you have to order more thankfully the shipping costs are much less than CO2 tanks.
Other Homebased Methods to make Carbonated W
ater from Scratch Without a CO2 Tank
These two other methods are all home-based and not regulated or tested by the federal government, please be safe, remember you are dealing with compressed gas and other potentially dangerous elements.
The other two methods are:
