Best Overall: SodaStream Source Home Soda Maker Starter Kit
One of the first brands to make soda makers popular, it’s no surprise that SodaStream tops our list. This model comes with a 4-ounce starter cylinder of CO2 for carbonating up to 6 liters of soda, depending on how fizzy you like your water. That starter cylinder can be replaced with a 60-liter cylinder that will make up to 60 liters of fizzy water, or it might make much less if you like your water with extra bubbles. The kit comes with a coupon for a free 60-liter cylinder as well. Because of its popularity, these CO2 cylinders can be found at many retail locations as well as online. A 60-liter cylinder costs about $30 to purchase a full tank, and about $15 to exchange an empty tank for a full one.
You can choose one of three levels of fizziness, and the proprietary snap-lock bottle snaps in and out of the machine for secure carbonating. The bottle has a special fizz-preserving bottle cap for storing the carbonated drinks as well. A two-pack of extra one-liter bottles is will cost about $16. The company also has more than 60 flavorings available for purchase that enable you to create your own sodas by adding them to the water after it’s carbonated.

Best Budget: iSoda DrinkMate Mini Hand Held Carbonated Soda Maker
Small and inexpensive, this soda maker is easy to carry to parties and picnics and is designed to create smaller bubbles that last longer. The kit includes a soda maker, a one-liter bottle, and six chargers. The quick-connect bottle attaches to the carbonating unit securely and can be used with any iSODA machine, if you decide you want to have several different machines.
This uses single-use (8-gram) CO2 cartridges that are recyclable. There are many branded and generic cartridges on the market that can be used with this soda maker. In bulk, you can buy them for less than 35 cents each.
There’s no adjustment for the amount of fizz, but if you want a super-fizzy drink, you can immediately re-fizz the water with a second charger to add more carbonation
Extra one-liter bottles are available for $20 for two, and 1/2-liter bottles are $18 for two.

Runner-Up, Best Overall: Sodastream Crystal Starter Kit
Beautiful, functional, and efficient, the Crystal starter kit from SodaStream includes a reusable glass carafe rather than plastic and makes the process faster and easier with quick bottle flask insertion, so there’s less fiddling to get the bottle in place. For easy cleaning, the glass carafe is dishwasher safe.
This unit is compatible with 60-liter CO2 cartridges. It comes with a mini CO2 cartridge that makes up to 9 liters of sparkling water to get you started, along with a mail-in rebate for your first 60-liter CO2 carbonator.

Runner Up, Best Budget: Hamilton Beach Fizzini Hand-Held Carbonated Soda Maker
If you’re looking for a small, portable, inexpensive way to make carbonated water on occasion, look no further. The carbonating unit fits onto the bottle and secures with a quarter-turn. This uses proprietary 8-gram CO2 cartridges, and a starter pack of 10 cartridges is included. While this isn’t designed to accept the standard-sized CO2 cartridges (which are longer than the proprietary ones designed for this unit), some customers have worked out ways to use the standard cartridges.
This has fizz control that adjusts with the turn of a knob and the included BPA-free bottle holds one liter.Continue to 5 of 8 below.

Best Multitasker: DrinkMate Carbonated Soda Maker
Unlike other soda makers that should only be used to carbonate water, this soda maker can be used to carbonate any liquid. (Hello homemade sparkling wine!) The kit includes a quick-connect bottle that has lines to indicate the proper volume, and a three-ounce CO2 cylinder.
The level of carbonation is variable, depending on how long you press the buttons, and you can leave the carbonation infuser attached to the bottle to better maintain the carbonation and to add more bubbles, if desired.
This unit can also use the 60-liter SodaStream tanks, and some users have adapted it to use paintball tanks, as well. (Although, there are concerns about whether the CO2 used in paintball tanks is food safe.) The 60-liter SodaStream tanks cost about $30 to purchase full, and it costs about $15 to exchange an empty tank for a full one.
This uses iSODA bottles. Additional one-liter bottles are available for about $20 for two, and 1/2-liter bottles are about $18 for two. Extra fizz infusers are available for about $22.

Best Portable: Drinkmate Portable Carbonation Machine
This handy carbonation unit has the technology of larger carbonation machines with none of the bulk. It’s small enough to tuck into a briefcase or purse or picnic basket or leave in a drawer at work. Since it doesn’t require any power, you can take it with you to parties, picnics, or even carbonate water or juice on the road.
This includes the spritzer gun and a half-liter reusable bottle. Additional bottles are available separately. It also includes two 3-ounce CO2 carbonator cylinders that each carbonate up to 16 bottles of liquid, and more are available for purchase separately

Best for Small Spaces: Innovee Soda Siphon
If you don’t have space for a countertop unit for making fizzy water at home, a soda siphon can do the job without the extra parts. This siphon is made from aluminum, so it’s lightweight. The integrated pressure regulator and the threaded lid makes it safe to use.
For flavored sodas, carbonate your water, then add flavoring – you shouldn’t carbonate anything except water in the unit. The siphon holds 1 liter and is dishwasher safe. Since it only contains water, it’s just as easy to rinse it after use.
This requires standard 8-gram individual CO2 chargers, which are not included. It also includes an e-book with cocktail recipes.
Although the standard chargers are available in bulk quantities at affordable prices, if you make a lot of soda, it might be more affordable to use a soda maker that uses large CO2 tanks.

Best Easy to Use: Big Boss Soda Maker
This soda maker gets you started making fizzy water right away since it includes 10 recyclable CO2 cartridges. The operation is simple — just fill the bottle with water, place it in the soda maker, and twist the handle to carbonate the water.
There’s a window that lets you see if a cartridge is inserted, and a cartridge door release button that makes it easy to swap cartridges. With this soda maker, you can make up to 1 1/2 liters of soda at a time, so you’ll have plenty for movie night or for cocktails.
How We Tested
Our reviewers tested this top-rated soda maker daily for three months. They set it up in their kitchens and made soda at different carbonation levels to see how it performed. We asked them to consider the most important features when using this soda maker, from its design to its ease of use. We've outlined the major points here so that you, too, know what to look for when shopping.
What to Look for in a Soda Maker
Versatility Many soda makers are designed for carbonating water and adding flavor after, but some can be used to carbonate any liquid you like, including fruit juices, cocktails, and wine. If you’re typically making plain carbonated water, you probably don't need a model that’s able to carbonate your iced tea.
Size of CO2 tanks Soda makers can use small (usually 8-gram) CO2 cartridges, medium-sized 3-ounce tanks, or small cylinders (14 ½ ounces, usually described as 60 liters) of CO2 to carbonate the liquid. Some models are restricted to one size, while others can use multiple sizes or even be converted to use the large refillable tanks intended for beer brewing. If you’re planning on making soda regularly, a larger tank is likely a better bet.
Size While some countertop machines are the size of small coffee makers, others are much more portable. Countertop units are usually able to accommodate larger CO tanks — so you won’t need to replace them as often — while portable models are great for tucking into a picnic basket or taking to a potluck or party.

What We Like
Easy to use
Customizable carbonation levels
What We Don't Like
Inconvenient to exchange CO2 carbonators in person
This soda maker came very highly recommended by our testers: “It's so easy to use and gets the water really fizzy,” noted one reviewer. Other highlights were its sleek design and ability to achieve different carbonation levels. “You can customize the amount of carbonation that you put into the water,” explained one tester. “I'm really picky about fizziness — I like a lot — and this machine got the seltzer to the perfect level for me.” The only downside of this soda maker? “You have to exchange the CO2 carbonators in person,” reported one reviewer. “We go to Bed Bath & Beyond, but I wish there was a system where you could mail them in.”
