Mejores máquinas para hacer agua con gas en 2026: comparativa real

Best sparkling water makers of 2026: a real comparison

If you're looking for a home soda maker, you already know there are options for every taste and budget. The problem is that most comparisons on the market don't tell you what really matters: how much you'll pay per liter over the next few years, not just the price of the appliance on the day you buy it.

We've analyzed the 5 most popular models in Spain in 2026 with a clear criterion: what truly pays off in the long run, without hidden costs.

What nobody tells you before buying a soda maker

The price of the machine is just the beginning. Two things determine how much you'll actually spend:

1. The cylinder system: standard screw-in vs. Quick Connect

This is the most important decision and the least explained in advertisements. There are two cylinder connection systems on the market:

  • Standard M18x1.5 screw-in — the most widespread system. Compatible with cylinders from multiple suppliers, giving you price freedom. Cylinders from ~€16.5 with refill plans. Models using this system: Burbujito, Aarke Carbonator 3, BRITA SodaONE, SodaStream Terra.
  • Quick Connect (SodaStream proprietary system) — only works with SodaStream cylinders. Refill price: ~€30-35 per cylinder. No alternative. Models using this system: SodaStream Art, SodaStream Duo, SodaStream Spirit.

If you consume 5 liters of sparkling water per week, the difference between one system and another can exceed €100 per year in cylinders alone.

2. The body material

The vast majority of soda makers on the market have a plastic body. They work well for the first few months, but over time they accumulate odors, degrade, and become more difficult to clean thoroughly. The alternative is stainless steel — more durable, more hygienic, and no plastic residues in contact with water.

Detailed analysis of each model

Burbujito — Congas Spain

Full 304 Stainless Steel Standard screw-in €200 Starter Pack Spanish company

Burbujito is the soda maker from Congas Spain, manufactured entirely from 304 stainless steel — including the carbonation nozzle, a detail very few machines on the market can claim. No plugs, no cables, no plastic in contact with water.

What differentiates it from the rest is not just the material: it's the system behind it. With Congas's Soda Club, cylinders arrive home before they run out and empty ones are collected in the same delivery, at €0.21/liter — the lowest price in this analysis. The Starter Pack (€200) includes the machine, 2 CO₂ cylinders (up to 480 liters), and 2 reusable 1-liter bottles valued at €40, which brings the actual net price of the machine to around €160.

LFGB, FDA, and ISO9001 food certifications. Built to last decades, not seasons.

✓ Pros

  • Full 304 stainless steel body (unique in its range)
  • Home delivery refill system — no need to travel
  • Lowest price/liter on the market with Soda Club (€0.21)
  • No plugs, no cables
  • Spanish company with local support
  • No commitment to the Soda Club

✗ Cons

  • Higher upfront cost (€200 for the Starter Pack)
  • Only available on the Congas website — not on Amazon or large retailers
  • Shipping only to peninsular Spain

SodaStream Terra

Plastic Standard screw-in ~€76 Global brand

SodaStream's best-selling model in Europe. Plastic body with a Snap & Lock system for bottle attachment without screwing. Uses standard screw-in cylinders, meaning it is compatible with cylinders from Congas and other brands — a significant advantage over the brand's Quick Connect models.

For those looking for an economical entry into the world of soda makers without compromising cylinder freedom, the Terra is a solid option. Its weaknesses are the material (plastic) and that the included bottles have an expiration date marked by SodaStream.

✓ Pros

  • Low entry price (~€76)
  • Standard screw-in — compatible with cylinders from any supplier
  • Easy to find (Amazon, El Corte Inglés, MediaMarkt)
  • Dishwasher-safe bottles

✗ Cons

  • Plastic body — accumulates odors over time
  • Bottles with expiration date (must be replaced)
  • No proprietary home refill service
  • Higher price/liter than Burbujito without a refill plan

SodaStream Art

Plastic + exterior metal Quick Connect — proprietary cylinders ~€103

The Art adds a metallic lever and a more refined design to the SodaStream system, but it has a significant problem: it uses the Quick Connect system, which is only compatible with SodaStream cylinders. This means you cannot use cylinders from Congas or any other standard screw-in supplier.

The refill price with Quick Connect is around €30-35 per cylinder (up to 60 liters), which translates to ~€0.58/liter — almost triple the most economical option in this analysis. Attractive on the countertop, but expensive to maintain.

✓ Pros

  • Attractive design with metallic lever
  • Widely available in physical stores
  • Recognized brand with good spare parts network

✗ Cons

  • Quick Connect: SodaStream cylinders only — no price alternative
  • ~€0.58/liter — the most expensive in this analysis
  • Plastic body despite the price
  • The "exterior metal" is not food-grade stainless steel

Aarke Carbonator 3

Exterior stainless steel Standard screw-in ~€197 Swedish design

The premium Scandinavian option. The Aarke Carbonator 3 has a very refined stainless steel design and uses a standard screw-in, giving it cylinder freedom. At a similar price to Burbujito's Starter Pack (~€197), but without including cylinders or 1-liter bottles — the included bottle is 800ml.

The point to consider is that the Aarke's stainless steel is exterior — the internal mechanism and carbonation nozzle are not necessarily made of the same material as the body. Burbujito, on the other hand, specifies 304 stainless steel throughout the entire assembly, including the nozzle, with LFGB and FDA food certifications.

✓ Pros

  • Very refined premium design
  • Standard screw-in — compatible with cylinders from any supplier
  • No cables or plugs
  • Good reputation for durability

✗ Cons

  • ~€197 without cylinders or 1L bottles included
  • Included bottle is 800ml (1L is a separate accessory)
  • No proprietary home refill service in Spain
  • Imported — no local Spanish distribution

BRITA SodaONE

Plastic + steel elements Standard screw-in ~€73

The most economical option in this analysis. The BRITA SodaONE uses standard screw-in and has some stainless steel elements in the nozzle and grid, but the main body is plastic. Good entry price if budget is the main factor and you already have access to standard screw-in cylinders.

BRITA is known for its water filters, not for soda makers — aftermarket support and the spare parts network in Spain are more limited than the previous options.

✓ Pros

  • Very low entry price (~€73)
  • Standard screw-in — compatible with Congas cylinders
  • Easy to clean (unscrewable nozzle)
  • Recognized brand in Europe

✗ Cons

  • Mainly plastic body
  • Limited spare parts network and support in Spain
  • No home refill service
  • PET bottle — not steel or glass

Which is the best soda maker for each case?

There's no single answer — it depends on what you prioritize. Here's the honest summary:

Best material + best price/liter Burbujito (Congas Starter Pack) — full 304 stainless steel and €0.21/liter with Soda Club
Lowest entry price BRITA SodaONE (~€73) or SodaStream Terra (~€76) — both with standard screw-in
Best premium design Aarke Carbonator 3 — Scandinavian aesthetic, standard screw-in, but no cylinders included
Avoid SodaStream Art if long-term cost is a concern — Quick Connect ties you to a price ~3x higher per liter

The real cost over 2 years: the calculation nobody makes

Let's look at the numbers. Average family consumption: 5 liters per week = ~260 liters per year = ~520 liters over 2 years.

Option Machine Cylinders 2 years Total 2 years
Burbujito + Soda Club €200 ~€109 (€0.21/L) ~€309
SodaStream Terra + loose cylinders €76 ~€177 (€0.34/L) ~€253
SodaStream Art + Quick Connect €103 ~€301 (€0.58/L) ~€404
Aarke C3 + standard screw-in cylinders €197 ~€109 (€0.21/L) ~€306
Bottled water from supermarket €0 ~€312 (€0.60/L approx.) ~€312

The conclusion is clear: any standard screw-in soda maker with a good refill plan is more cost-effective than bottled water. The difference between Burbujito and the SodaStream Art over 2 years exceeds €90 — and that's without counting that stainless steel lasts decades while plastic degrades.

Frequently asked questions about soda makers

What is the difference between standard screw-in and Quick Connect?
Standard screw-in (M18x1.5) is a universal system compatible with cylinders from multiple manufacturers. Quick Connect is a proprietary SodaStream system that only works with their own cylinders — with no possibility of using cheaper alternatives. If you have the freedom to choose, standard screw-in is always the better long-term option.
How long does a CO₂ cylinder last at home?
A 425g cylinder produces up to 60 liters of sparkling water. For a person who consumes 1 liter daily, it lasts about 2 months. For a family of 4, between 3 and 4 weeks. With the Congas Soda Club, you receive cylinders automatically before you run out of gas.
Are soda makers safe for home use?
Yes. All machines in this analysis comply with European safety regulations. Food-grade CO₂ is completely safe — it's the same gas used in industrial soft drinks. Burbujito also has LFGB, FDA, and ISO9001 certifications.
Can I use Congas cylinders with my SodaStream Terra?
Yes. The SodaStream Terra uses a standard M18x1.5 screw-in, just like Burbujito. Congas cylinders are fully compatible with the Terra, and vice versa. The models that are NOT compatible are those that use Quick Connect: SodaStream Art, Duo, Spirit, and Source.
How much can I save annually by making sparkling water at home?
It depends on your consumption. A family that drinks 5 liters of sparkling water per week bought from a supermarket (at ~€0.60/liter) spends about €156 per year on sparkling water alone. With the Congas Soda Club at €0.21/liter, the cylinder cost drops to ~€55 per year. The savings exceed €100 annually — not counting the savings in plastic and trips to the supermarket.
