How to Choose a Soda Maker

Everything you need to know before buying.

Buying a soda maker should be simple, but the options can be confusing. This guide breaks down everything that actually matters — and what you can ignore.

5 Questions to Ask Yourself

  1. How much sparkling water will you drink?
    • Light use (5-10L/week): Any model works
    • Heavy use (20+ L/week): Prioritize easy cylinder changes
  2. Do you want to carbonate anything besides water?
    • Water only: Any SodaStream or Aarke
    • Juice, wine, cocktails: DrinkMate only
  3. Do you care about aesthetics?
    • Yes: Aarke ($229) or SodaStream Art ($130)
    • No: SodaStream Terra ($89) — same function, lower price
  4. Do you want glass bottles?
    • Yes: SodaStream Duo only
    • No: Any model
  5. What's your budget?
    • Under $100: SodaStream Terra
    • $100-150: SodaStream Art or DrinkMate
    • $150-200: SodaStream Duo
    • $200+: Aarke Carbonator 3

Understanding CO2 Systems

This is the most important distinction between soda makers — it affects convenience and running costs.

Quick-Connect (Pink Cap)

Used by: SodaStream Terra, Art, Duo

  • ✓ Push to connect — 5 seconds
  • ✓ No threading, no tools
  • ✓ Idiot-proof
  • ✗ Slightly more expensive refills (~$17-20)

Screw-In (Blue Cap)

Used by: SodaStream Spirit, Aarke, DrinkMate

  • ✓ Cheaper refills (~$15-17)
  • ✓ More widely available
  • ✓ Third-party adapter options
  • ✗ Threading can be annoying

Our take: Quick-connect is worth the $2-3 per cylinder premium. Swapping cylinders on screw-in machines is one of the few genuinely annoying aspects of owning a soda maker.

Bottle Types: Glass vs Plastic

Plastic Bottles (Standard)

  • Pros: Lightweight, shatterproof, dishwasher-safe, holds pressure well
  • Cons: Some people dislike drinking from plastic, needs replacing every 2-3 years
  • Used by: All models

Glass Carafes

  • Pros: More elegant, no plastic touching water, dishwasher-safe
  • Cons: Heavy, breakable, can't store carbonated water under pressure
  • Used by: SodaStream Duo only

Important: The glass carafe on the Duo is for immediate use — carbonate, serve, done. You can't store pressurized carbonated water in glass like you can in the plastic bottles.

Running Costs Explained

The Math

Cost Element Amount
CO2 cylinder exchange $15-20
Liters per cylinder ~60L
Cost per liter $0.25-0.35
Store-bought sparkling water $1.00-2.00/L
Savings ~80%

Break-Even Point

A $90 SodaStream Terra pays for itself after ~60-90 liters of sparkling water — about 3-4 months for a regular user.
