If sparkling water is your go-to refresher, consider buying a soda maker. Making the bubbly stuff yourself means no longer having to lug bottles and cans home from the grocer, or haul them in from the porch after a delivery. It potentially frees space in your pantry, cabinets, fridge, garage, or basement, too. And it translates to fewer empties in the waste stream.

To help you find the best soda maker, Consumer Reports tested widely sold models from Aarke, Drinkmate, Soda Sense, and SodaStream. Soda makers serve up a number of advantages over store-bought seltzer. Using one allows you to:

• Save money. If, for example, you spend $80 on the highly-rated SodaStream Terra and make one liter a day—rather than buying seltzer at 86 cents per liter—you’ll break even in four months. That includes buying two replacement cylinders of carbon dioxide at an average of $22.50, including shipping, from a subscription service. (Replacement CO₂ cylinders cost between $15 and $30 each at walk-in and e-retailers.) To see how much seltzer you’d have to drink for a soda maker to be worth the cost, plug your consumption level into our soda maker calculator.

• Reduce waste. The bottles are reusable, and the CO₂ cylinders are refillable. The machines we list below include one plastic liter bottle. (You can buy more bottles, including glass bottles for some brands, and smaller personal bottles.)

• Customize your fizz. All six models here let you control the level of carbonation. And you can reattach a bottle you’ve already carbonated to add fizz if it goes flat.

How CR Tests Soda Makers

We made dozens of bottles of seltzer to evaluate the six soda makers in our tests. We rate each model on how easy it is to use, including when attaching and detaching bottles and using the controls. We use standard 14-ounce CO₂ cylinders, which work in any soda maker.

To judge whether a soda maker produces equally fizzy bottles of seltzer, we start by using ice-cold water, which carbonates better, and we install a gauge on the cap to measure the gas pressure inside each bottle. “You can expect that bottles with the same internal gas pressure will produce about the same amount of fizz,” says Bernie Deitrick, the engineer who leads soda-maker testing at CR. We also check the maximum gas pressure that each machine can add to water, for people who want a real snootful of scintillation.

In the bottle-cap test, we see how easy it is to release pressure from each brand’s gassed-up bottle without spilling soda everywhere. “When a bottle that’s been highly carbonated sits for a while—or has warmed up or been shaken—some of the gas that’s been pumped into the water enters the space at top of the bottle, so the gas pressure inside rises,” Deitrick says. “If the pressure isn’t released smoothly, the soda can come out fast, and you get a fizzy mess.”

For the icing test, we examine whether the CO₂ nozzle ices up—a problem with some designs that can affect the fizz level. When high-pressure CO₂ exits the injector, it drops in temperature and can freeze some water on the nozzle. When the injector is blocked, gas can be diverted to the bottle’s side—instead of directly down into the water—so it doesn’t carbonate as well.

So how did the soda makers in our tests do? Read on for ratings and reviews of each one.

CR’s take: The SodaStream Fizzi One Touch, the only machine in our tests that must be plugged into an outlet, earns our highest marks. Uniquely, it has three preset levels of carbonation, each with its own control button that you lightly touch to activate. Because the electric-powered One Touch doesn’t require you to hold down a button or lever, it’s ideal for someone with limited hand strength. Deitrick says the One Touch’s “medium” button makes soda about 1 ½ times as fizzy as “low,” and the “high” button doubles the bubbles of “low.” But no matter how much carbonation you want, you’ll get consistent results. The unit’s one drawback? It’s not ideal if you like your soda just a tad spumante. “It’s pretty carbonated at the lowest level, and you can’t go below that,” Deitrick says.

CR’s take: The highly-rated SodaStream Terra is among the easiest soda makers to use: Insert your bottle top in a clamp, push the clamp into place, and press the button on top. The Terra offers other bubbly benefits; for one, it needs no electricity to work. Performance-wise, it doesn’t ice up when operating; its cap stays on under pressure; and because it has no preset carbonation levels, you can vary the amount of fizz by the number of times you press the button.

In performance, the Terra sits between the stellar SodaStream Fizzi One Touch and the well-rated SodaStream Fizzi (see “Other Good Options,” below). It’s unique, though, in its snap-on mounting for CO₂ cartridges; we found the new “quick connect” design easier to use than the older, screw-in setup of those other models. (The new, pink cartridges you’ll need for this unit cost the same and can carbonate the same volume as the older cartridges.)

The Terra’s manual control button may not be the easiest to use for those with limited hand strength. But otherwise, it’s an appealing combination of price and performance.

CR’s take: If you want to make a stylish statement on your bar or kitchen counter—and don’t mind the eye-popping price—check out the slim, metal-clad Aarke Premium Carbonator. Its screw-in bottle attachment isn’t quite as easy to use as the snap-in mounts of the SodaStream models, but we liked that it uses a lever to add gas, rather than a push button. This model’s carbonation nozzle also ices up somewhat, which means you don’t consistently get the same amount of gas in each bottle. “That doesn’t change the taste,” Deitrick says, “though the soda may feel different in your mouth if the carbonation level isn’t the same.” You can use SodaStream bottles with the Aarke; both brands’ bottles cost about the same, but our quick perusal of retailers showed that the SodaStream bottles were available in more stores.

CR’s take: Unlike higher-rated soda makers in our tests, the Soda Sense Soda Sensei claims to carbonate juice and a variety of other beverages, including iced tea, wine, and cocktails. When we used apple juice to test that claim, the Soda Sensei succeeded. Deitrick found the results “delightful”—like hard cider without the kick.

Other features of the Soda Sensei, however, make it a so-so selection. Icing is a bigger problem for this unit than for the others. The Soda Sensei’s injection nozzle sits deep in the water, making more of it vulnerable to freezing, so it doesn’t carbonate as consistently. This model also requires a bit more work than the others here to make seltzer. You need to put a large, specially designed cap on the Soda Sensei bottle before you add gas. Once you’re done carbonating, you have to release some gas by pushing a tab on the cap, wait for the hissing of the escaping gas to stop, and then replace the large cap with a small cap. Notably, we found that once we put the small cap on after adding a lot of gas, it was hard to slowly release some of the resulting high pressure. So sometimes the cap popped off, spewing seltzer everywhere. 

The Soda Sensei costs a few dollars less than the similarly-designed DrinkMate Sparkling Water and Soda Maker (see “Other Good Options,” below), and earned identical marks in our tests. Both require the same carbonation bottles, ones that differ from the more common SodaStream bottles.

CR’s take: If you’re looking for a very good machine at a reasonable price, check out the SodaStream Fizzi. It scores almost as well in making consistent fizziness as the top model in our ratings, the Fizzi One Touch, but it costs less. It’s among the easiest soda makers to use, too—insert your bottle top in a clamp, push the clamp into place, and push the button. Like the other SodaStream models, the Fizzi’s bottle caps stay on well when the contents are under pressure. The CO₂ injector sits at the top of the water line, so gas entering the bottle doesn’t freeze the water in the nozzle and ice up the works. You can vary the carbonation simply by pressing the button for longer or shorter times.

CR’s take: The Drinkmate Sparkling Water and Soda Maker—which also goes by the names Drinkmate Carbonated Beverage Maker and Drinkmate OmniFizz—claims to carbonate juice and a variety of other beverages, including iced tea; wine; and cocktails. It’s designed similarly to the Soda Sense Soda Sensei, and performed identically in our tests. For instance, its cap sometimes popped off during our high-pressure test, spilling seltzer everywhere. And while we found this push-button unit generally very easy to use, its results weren’t consistent. In part that’s because the Drinkmate also tended to ice up during carbonation.

We got good results carbonating apple juice, however, so if you want an alternative to the Soda Sense Soda Sensei and can tolerate its weaknesses, it’s an option. The Drinkmate and the Soda Sensei require the same carbonation bottles, ones that differ from the more common SodaStream bottles.
