Wirecutter's Top SodaStream Picks
Wirecutter has tested SodaStream machines for years, and a few models consistently rise to the top. The review process weighs carbonation quality, ease of setup, how often you'll need to swap cylinders, and whether the machine stays reliable after hundreds of uses. For most households, the SodaStream Terra and SodaStream Fizzi are the two machines that earn a clear recommendation, with the Duo and Power models making appearances for specific use cases.

Wirecutter does not treat all SodaStream machines equally. The testing favors units that carbonate quickly, hold pressure reliably, and use standardized CO2 cylinders that are easy to find and swap. Machines that require proprietary parts or have fiddly latch mechanisms tend to score lower because they introduce small daily frustrations that add up over months.
SodaStream Terra
The Terra is Wirecutter's pick for people who want a machine that looks like kitchen equipment rather than a plastic novelty. It has a glass carafe, a magnetic capture ring that holds the bottle steady during carbonation, and a broad base that keeps it from tipping when you press the carbonation button. Wirecutter notes that the Terra carbonates a full liter reliably in one or two pumps, and the glass bottle is dishwasher safe, which extends its lifespan compared with plastic alternatives.
SodaStream Fizzi
The Fizzi is Wirecutter's budget-friendly, no-nonsense option. It uses a snap-on bottle and a simple carbonation lever, and the entire unit is compact enough to store in a cabinet. Wirecutter's testers found that the Fizzi produces consistent fizz on standard 1-liter bottles, though the plastic bottle shows wear faster than the Terra's glass carafe. For renters or people who want a low-commitment entry point, the Fizzi remains a strong choice.
SodaStream Duo
The Duo earns a mention for households that go through sparkling water quickly. It has a larger footprint and a bigger carbonation chamber, which means fewer refills when you are hosting guests or stocking a fridge for a family. Wirecutter flags that the Duo takes up more counter space and is louder during carbonation than the Terra or Fizzi, but the trade-off is speed and volume.
SodaStream Power
The Power model adds an electric pump to the standard SodaStream formula, which removes the hand-press step entirely. Wirecutter notes that the Power is convenient for people who want set-it-and-forget-it carbonation, but the machine is bulkier and more expensive than the manual options. It makes sense mainly for users who plan to carbonate large batches or have hand-strength concerns.
What Wirecutter Tests Look At
Wirecutter's SodaStream evaluation covers several dimensions that matter more than raw specs:
- Carbonation consistency across multiple bottles and refill cycles
- Ease of cylinder swapping and availability of replacement parts
- Bottle durability, dishwasher safety, and long-term clarity
- Noise level and countertop footprint during use
- Cost per liter once you factor in the machine, cylinders, and syrups
CO2 Cylinder and Syrup Costs
A hidden part of the SodaStream equation is the ongoing cost of carbonation and flavoring. Wirecutter recommends keeping a spare cylinder on hand so you are never stuck without sparkling water. Standard 14.5-ounce cylinders work across most SodaStream models, and wirecutter's reviewers suggest buying cylinders in multipacks to reduce per-unit shipping costs. Syrup pods are another factor; the official SodaStream flavors work reliably, but third-party syrups and juice concentrates can lower the cost per glass without sacrificing carbonation quality.
Which Model Wirecutter Recommends Most Often
The SodaStream Terra earns the strongest overall endorsement from Wirecutter for most buyers. It balances build quality, carbonation performance, and daily usability in a way that holds up after years of use. The Fizzi is the fallback for tight budgets or small kitchens. The Duo and Power are situational picks that make sense only if your household's volume or physical needs justify the larger footprint and higher price.
