Sparkling water machines are a simple category — compress CO2 into cold water, done. But the experience of using them varies more than you'd expect. The SodaStream E-Terra is the reliable, affordable, ecosystem-standard choice. The Aarke Carbonator 3 is Swedish-designed, all-metal, and a beautiful kitchen object. Both use the same SodaStream CO2 cylinder. The choice is mostly aesthetic.
Aarke Carbonator 3
The Aarke Carbonator 3 wins on design and build quality; the SodaStream E-Terra wins on price and is the better starting point for most households.
Specs Comparison
| Spec | SodaStream E-Terra | Aarke Carbonator 3 |
|---|---|---|
| Body material | Plastic | Stainless steel |
| Mechanism | Push button | Lever arm |
| CO2 cylinder | SodaStream standard | SodaStream standard |
| Bottle compatibility | All SodaStream bottles | Standard SodaStream (most) |
| Carbonation control | Consistent (less fine control) | Better tactile control via lever |
| Available finishes | 2–3 plastic colors | Multiple metal finishes |
| Price (MSRP) | ~$89 | ~$199 |
Carbonation and Performance
Both machines use standard SodaStream CO2 cylinders and produce comparable carbonation levels. The Aarke Carbonator 3's lever-arm mechanism gives slightly more tactile feedback per press, making it easier to achieve consistent carbonation levels.
The SodaStream E-Terra uses a button-push mechanism. It's consistent and requires no real technique, but experienced users note it's slightly harder to fine-tune carbonation intensity compared to Aarke's lever.
For perfectly carbonated water every time, both work. Aarke's lever is better for dialing in light, medium, or heavy carbonation by feel.
Design and Build Quality
The Aarke Carbonator 3 is made entirely of stainless steel with no plastic components visible from the front. It looks like a precision appliance from a Scandinavian design studio — because it is. On a kitchen counter, it's genuinely striking.
The SodaStream E-Terra has a mostly plastic body with a clean, functional design. It's not unattractive, but it's clearly a utilitarian product rather than a design object.
If your kitchen showcases its appliances, the Aarke's premium materials justify a significant portion of the price premium.
Bottle Compatibility
The SodaStream E-Terra is compatible with all standard SodaStream bottles (0.5L and 1L), including the DWS (dishwasher-safe) bottles. Wide bottle compatibility is the SodaStream ecosystem's strength.
The Aarke Carbonator 3 works with standard SodaStream bottles but doesn't have the snap-in mechanism for some newer SodaStream bottle formats. Most standard bottles work fine.
For households who already own SodaStream bottles, both machines work interchangeably with the common bottle styles.
SodaStream E-Terra Strengths
- Affordable — typically $80–$100 less than Aarke
- Wide bottle compatibility including newer SodaStream DWS bottles
- Push-button mechanism is simple and consistent
- Most accessible entry point to home sparkling water
Aarke Carbonator 3 Strengths
- All-stainless steel construction — no plastic in the main body
- Lever-arm mechanism gives tactile carbonation control
- Beautiful Scandinavian design that looks premium on any counter
- Available in multiple metal finishes (polished steel, matte black, rose gold)
SodaStream E-Terra Weaknesses
- Plastic body doesn't feel premium
- Slightly harder to fine-tune carbonation level per bottle
- Design is functional but not a counter showpiece
Aarke Carbonator 3 Weaknesses
- Costs $80–$100 more than the E-Terra for similar carbonation output
- Doesn't snap with all newer SodaStream bottle formats
- Design premium is real but purely cosmetic
Best For
- a: Anyone starting with home sparkling water who wants the most cost-effective entry point
- b: Design-conscious households where kitchen appliances are display-worthy and build quality matters
FAQ
How many liters does one CO2 cylinder make?
A standard SodaStream cylinder makes about 60 liters of sparkling water. Exchange cylinders cost around $15 at most supermarkets or direct from SodaStream.
Can you use the Aarke with non-SodaStream CO2 cylinders?
Some third-party cylinders with the same thread standard work with Aarke, but Aarke officially recommends SodaStream cylinders. Non-standard cylinders may not fit correctly.
Is home sparkling water cheaper than buying sparkling water?
Yes — once you factor in the machine cost, home sparkling water runs about $0.25 per liter vs $0.70–$1.50 per liter for canned or bottled sparkling water. The machine typically pays for itself within 6–12 months.
