What You're Really Paying For
The Carbonator 3 and Pro share the same core: stainless steel body, lever mechanism, and identical carbonation. The $120 premium buys you two things:
1. Glass Carafe vs PET Bottle
The Pro comes with a glass carafe instead of a plastic bottle. This matters if:
- You want to serve directly from the carafe at dinner
- You prefer glass aesthetically
- You have concerns about plastic (though PET is safe)
The Carbonator 3's plastic bottle is high-quality and taste-neutral, but it's obviously not as elegant as glass.
2. Auto-Seal Cap
The Pro's carafe has a spring-loaded cap that automatically seals when you remove it from the machine. No fumbling with a separate cap while CO2 escapes.
This is genuinely clever engineering — the carbonation stays locked in the moment you remove the carafe. The Carbonator 3 requires you to screw on a cap after removing the bottle.
Carbonation Quality
Identical. Both use the same mechanism, same CO2, same pressure. The sparkling water that comes out is exactly the same. If you're buying the Pro thinking you'll get better carbonation — you won't.
Practical Considerations
Durability
The Pro's glass carafe is obviously breakable. Drop it on a tile floor and you're buying a new one (~$50). The Carbonator 3's PET bottle is virtually indestructible.
Capacity
Both hold 800ml — slightly less than the 1L bottles SodaStream uses. For families, you may find yourself making multiple batches.
Color Options
The Carbonator 3 comes in many finishes: stainless steel, matte black, copper, brass/gold, white, and more. The Pro only comes in steel and matte black. If you want a specific aesthetic, the 3 offers more flexibility.
Is the $120 Premium Worth It?
For most people: no. The Carbonator 3 is already a premium product at $229. The Pro's glass carafe and auto-seal are nice-to-haves, not need-to-haves.
The Pro makes sense if:
- You'll serve sparkling water at dinner parties directly from the carafe
- You have a strong preference for glass over plastic
- You want the absolute nicest version of an Aarke
- Budget isn't a primary concern
Otherwise, the Carbonator 3 delivers 95% of the experience at 65% of the price.
Our Recommendation
Get the Carbonator 3 if:
- You want premium Aarke design at the best price
- Plastic bottles don't bother you
- You want more color options
- You'll use it mostly for personal/family consumption
Get the Carbonator Pro if:
- Glass carafe for serving is important to you
- You want the auto-seal convenience
- Budget isn't the priority — you want the best
- You entertain guests regularly
The Bottom Line
The Carbonator 3 is our recommendation. It's already a premium product that looks stunning and performs excellently. The Pro is beautiful, but the $120 upgrade primarily buys you a glass carafe — which is nice, but not transformative.
If you're debating between the two, get the 3 and spend the $120 savings on CO2 refills. You'll have sparkling water for months with that difference.
