In This Review
What's New vs Carbonator 3
The Carbonator Pro launched in 2023 as Aarke's premium tier, sitting above the already-premium Carbonator 3.
Key differences:
| Feature | Carbonator Pro | Carbonator 3 |
|---|---|---|
| Price | $349 | $229 |
| Bottle | Glass carafe (included) | PET plastic (included) |
| Cap system | Auto-seal | Standard screw cap |
| Carafe size | 800ml | 800ml (PET) |
| Weight | 2.9kg | 1.5kg |
| Finishes | Steel, Matte Black | Multiple colors |
The Pro is fundamentally the same machine with two key upgrades: glass carafe and the ingenious auto-seal cap.
Design & Build Quality
Let's be clear: the Carbonator Pro is the most beautiful soda maker you can buy. It looks like it belongs in a Scandinavian design museum, not next to a toaster.
The body is solid stainless steel — not steel-look plastic, actual metal. The lever mechanism is machined to tight tolerances. Every surface is finished to a high standard. It weighs 2.9kg empty (heavy, but that weight means stability).
Color Options
- Stainless Steel — brushed metal, fingerprint-resistant
- Matte Black — powder-coated, very sleek
Unlike cheaper machines that hide the CO2 cylinder in a back compartment, the Pro integrates it into the design. The cylinder sits inside the main body — no visible tanks or ugly plastic covers.
The Glass Carafe System
The Pro's signature feature is the glass carafe with auto-seal cap. Here's how it works:
- Fill the carafe with cold water
- Insert into the machine (twist-lock)
- Lower the lever to carbonate
- Lift the carafe out — the cap automatically seals
- Serve directly at the table
The auto-seal is genuinely clever. As you remove the carafe, a spring-loaded mechanism closes the cap, keeping the carbonation locked in. No fumbling with a separate cap while CO2 escapes.
Glass vs Plastic
The glass carafe is elegant and you can serve directly from it — no transferring to a different container. It also avoids the plastic-taste concern some people have with PET bottles (though modern soda maker bottles are taste-neutral).
Downsides: glass is fragile, and replacement carafes cost $50+. If you drop it, that's an expensive oops. The carafe is also 800ml vs the 1L standard — you're making slightly less per batch.
💡 Carafe Care
The glass carafe is top-rack dishwasher safe. The auto-seal cap should be hand washed to keep the mechanism smooth.
Carbonation Performance
Here's the honest truth: the Carbonator Pro carbonates water exactly as well as a $90 Terra. CO2 is CO2, pressure is pressure. There's no premium carbonation happening here.
The lever mechanism is smooth and satisfying — smoother than the Carbonator 3, actually. It requires less force and has a more refined feel. But the end result in your glass? Identical fizz.
CO2 System
Like all Aarke machines, the Pro uses standard screw-in CO2 cylinders (blue cap). This means:
- Cheaper refills than SodaStream's quick-connect ($15 vs $18)
- More third-party options
- Refill adapters work if you want to use large tanks
Is It Worth $349?
Let's do the math. The Carbonator Pro costs $349. The SodaStream Terra costs $90. That's a $259 difference.
For that extra $259, you get:
- Stainless steel construction (vs plastic)
- Glass carafe with auto-seal (vs plastic bottle with screw cap)
- Significantly better design
- ... identical sparkling water
If you're buying a soda maker purely for function — to make cheap sparkling water — the Pro makes zero sense. You could buy a Terra and have $259 left over for ~17 CO2 refills (850 liters of sparkling water).
But if you:
- Care deeply about how your kitchen looks
- Want something you're proud to leave on the counter
- See value in premium materials and engineering
- Have the budget and don't mind spending on quality
... then the Carbonator Pro delivers something the Terra never will. It's a luxury item that also happens to make sparkling water.
🎯 The Right Comparison
Don't compare the Carbonator Pro to a Terra — compare it to other luxury kitchen items. A $300 kettle. A $400 toaster. A $500 espresso machine. In that context, a beautifully designed soda maker that you use daily isn't absurd.
Final Verdict
Aarke Carbonator Pro
The ultimate design statement
The Aarke Carbonator Pro is the best-built, most beautiful soda maker money can buy. The glass carafe and auto-seal cap genuinely improve the experience, and the stainless steel construction is in another league from plastic machines.
Is it worth $349? If you're asking that question, probably not. But if you saw it, thought "I want that," and just need to know it works well — it does. Exceptionally well.
