Are Sodastream Worth It? | Real Costs Per Liter

A SodaStream is worth it when you make sparkling water often, like the taste, and can swap CO2 locally at a fair price.

You’re not buying a gadget for bubbles. You’re buying a routine: fill a bottle, press a button, sip. If that routine replaces store-bought sparkling water you already pay for, the numbers can swing in your favor faster than you’d guess.

But if you only want fizzy drinks once in a while, or you hate dealing with cylinder swaps, a SodaStream can turn into a dusty counter ornament. This article helps you decide with plain math, real-life friction points, and a few practical habits that keep costs from creeping up.

What You Pay For And What You Get

A SodaStream setup has three cost buckets: the machine, the CO2, and anything you add to the water. The machine is the one-time hit. CO2 is the ongoing cost. Flavors and extras are optional, but they can quietly become the biggest line item.

Machine Price And What It Changes

Cheaper models carbonate just fine, but they can feel flimsy, and some rely on plastic bottles only. Higher-priced models tend to feel sturdier and may include glass carafes or a different bottle system. The taste in your glass can be identical across models; the difference is comfort, look, and how you like to pour and store.

CO2 Is The Real Meter

SodaStream cylinders are sold with a “60L” label, which is a ceiling, not a promise. The brand says a single cylinder can make up to 60 liters of sparkling water, and the real number shifts with your carbonation level and machine type. You can see the brand’s current CO2 options, including exchange and spare cylinders, on SodaStream’s CO2 cylinder page.

Translation: if you like soft sparkle, your cylinder lasts longer. If you like sharp, soda-like bite, it runs out sooner.

The Swap System Matters More Than The Machine

Most people don’t keep buying brand-new cylinders. They swap empties for refills. That refill price is what you should use for your break-even math, not the price of a brand-new cylinder. SodaStream lays out its exchange options and refill flow on its refill and exchange page, and the store listing for cylinder exchange is also on the brand site at CO2 Cylinder Exchange.

If you can swap cylinders at a nearby store, you get low hassle and predictable costs. If you need to mail cylinders, timing can add friction. Friction is what makes people quit.

What About CO2 For Drinks?

For plain sparkling water, a common question is whether the gas is suitable for food. In the U.S., carbon dioxide is listed in federal regulations for use in food under good manufacturing practice. The Electronic Code of Federal Regulations has the entry for carbon dioxide at 21 CFR 184.1240 (Carbon dioxide). It’s a handy reference if you like to ground decisions in official language.

Are Sodastream Worth It? Break-Even Starts With Your Habit

This is the part people skip: your break-even isn’t a single number. It’s a range that moves with three dials: how many liters you drink, how much fizz you like, and what you pay for refills.

Start with your current habit. Count what you already buy, not what you wish you drank. If you buy sparkling water weekly, SodaStream has a fair shot. If sparkling water is a “treat” twice a month, the math usually drags.

Simple Break-Even Shortcut

Use this shortcut when you don’t want spreadsheets:

• Pick your average store price per liter for sparkling water.
• Estimate your refill cost per liter from the “60L” label, then nudge it higher if you like heavy carbonation.
• The gap between those two numbers is your savings per liter.
• Divide the machine price by your savings per liter to see how many liters it takes to pay back.

If your savings per liter is tiny, your payback can take a long time. If your savings per liter is large, you can feel the win quickly.

To make that practical, here’s a set of variables that tend to push payback in either direction.

Cost Factors That Make The Difference

The table below is meant to be used like a checklist. You don’t need to hit each “good” condition for a SodaStream to make sense. Two or three can be enough if your usage is steady.

Factor	What Usually Helps	What Usually Hurts
Monthly liters made	40+ liters made at home	Under 15 liters made at home
Refill access	Local swap in one errand	Mail-only swaps or long drives
Carbonation level	Light to medium fizz	Heavy, soda-like fizz
Store water price	You buy pricier sparkling water	You buy low-cost multi-packs
Flavors and syrups	Mostly plain water	Frequent syrup use
Kitchen space	Easy counter spot and storage	Hidden away in a cabinet
Household size	Two or more frequent drinkers	One occasional drinker
Backup cylinder	One spare, no “out of gas” nights	Single cylinder, frequent gaps
Bottle care	Regular washing and rotation	Forgotten bottles, stale smell

Where SodaStream Feels Like A Win In Daily Life

Money is only half the call. The other half is whether you’ll actually use it. The people who keep using SodaStream tend to like at least one of these day-to-day perks.

It Cuts Store Runs For Bubbles

If you hate hauling cases of sparkling water, the switch can feel liberating. You keep water and CO2 at home, and you make bubbles when you want them. When it fits your routine, it feels smooth.

You Control The Bite

Some store brands feel flat. Some feel too sharp. With a SodaStream, you set the bite you want. You can do a gentle fizz for meals, then punch it up for a mocktail later.

Plain Sparkling Water Becomes The Default

If you’re trying to drink less soda, a fizzy water habit can help. Not by magic. It just gives you a fun texture without sugar. If you still want flavor, add a squeeze of citrus, a few drops of bitters, or a splash of juice you already have.

Where SodaStream Can Annoy You

Some pain points are small, but they stack. If you already know you hate this kind of upkeep, the “worth it” answer can flip.

CO2 Swaps Are A Chore If They’re Not Nearby

The refill process is simple on paper. In real life, you either need a store you already visit or an online system you don’t mind managing. If your nearest swap is out of the way, it’s easy to run out and stop using the machine for weeks.

Bottle Limits Can Feel Fussy

Plastic bottles have an expiration date for safe use, and they can pick up odors if they sit wet. Glass options can feel nicer, but they break, and some models restrict which bottles you can use. If you share the machine with a busy household, you’ll want a bottle plan that doesn’t turn into a constant sink pile.

Flavors Can Blow Up Your Budget

Syrups are fun, but they change the math. Many people buy a SodaStream for “cheaper sparkling water,” then spend more than they used to on flavor mixes. If you want the savings, treat flavors as an occasional thing and keep plain fizz as your baseline.

How To Get More From Each Cylinder

This section is about stretching your CO2 without turning your routine into homework.

Carbonate Cold Water

Cold water holds carbonation better than warm water. Start with chilled water and you often need fewer presses to get the same bite. That can stretch each cylinder.

Use A Consistent Press Pattern

If you mash the button wildly, you can burn through gas fast. Pick a pattern you like and stick with it. Many people settle into “two gentle presses” for light fizz or “three to four presses” for more bite, then tweak by taste.

Keep A Spare Cylinder

A spare sounds like extra spend. In practice, it keeps you from going flat for days. People who never run out tend to keep using the machine, which is where the value shows up.

What To Check Before You Buy

You can avoid most regrets with a quick pre-buy check. It takes five minutes.

• Find your nearest cylinder swap location and note the refill price.
• Measure the counter space where you’d keep the machine.
• Decide whether you want plastic bottles or glass carafes.
• Pick one drink you already buy often that you want to replace, like plain sparkling water.

If you can’t find an easy refill option, pause. Your refill path is the whole game.

Who Tends To Be Happy With SodaStream

This second table is a quick self-check. If you see yourself in the left column more than the right, a SodaStream usually lands well.

Good Fit	Maybe Skip
You drink sparkling water most days	You drink it a few times a month
You can swap CO2 during normal errands	You’d need special trips or shipping
You like plain fizz or simple add-ins	You want lots of branded soda flavors
You enjoy controlling carbonation level	You want identical taste each time
You have space for bottles and a spare cylinder	Storage is tight and clutter bugs you
You’re fine rinsing bottles after use	Dish chores already drive you nuts

Verdict You Can Trust

If you already buy sparkling water often, have a simple refill path, and like plain fizz, a SodaStream can save money and cut weekly hassle. If your usage is light or refills are a pain, it’s usually not worth it.

One last tip: if you’re on the fence, borrow a friend’s machine for a weekend or buy from a retailer with an easy return window. Two days of real use tells you more than any spec sheet.
