Best Soda Makers & Carbonated Drink Machines of 2025: Fizzy Water at Home

I bought my first soda maker because I was spending $40 a month on LaCroix and felt ridiculous about it. Six years and three machines later, I can tell you two things. The upfront cost pays for itself in about six months. And not all soda makers are worth your money. Some carbonate well and keep fizz for days. Others go flat in hours or feel like they’re going to explode when you twist the bottle off.

I tested seven machines across three categories: entry-level models that carbonate plastic bottles, premium stainless steel machines with glass carafes, and prosumer models for serious home carbonation. Here’s what I found.

What to Look For in a Soda Maker

Carbonation Method and Control

Most home soda makers use the same basic method: inject pressurized CO2 into cold water. The difference is in the control. Entry-level models give you one or two button presses — press once for light fizz, press three times for aggressive bubbles. Premium models let you hold the button for exact second counts, repeat-carbonate if your first attempt was weak, or use a pressure gauge that shows exactly how much CO2 dissolved. More control means more consistent results. A burp valve (pressure release) also matters — it lets you carbonate at higher pressure without the bottle bursting, and it extends the life of the CO2 cylinder.

CO2 Cylinder Compatibility

This is the hidden cost. Most machines use proprietary 60-liter or 130-liter CO2 cylinders that cost $30-40 to exchange. Over two years, the CO2 cost exceeds the machine cost. Machines that accept standard paintball CO2 tanks or 5-pound commercial tanks (with an adapter) let you refill at a sporting goods or welding supply store for $5-10 instead of $30. If you plan to carbonate heavily, compatibility with standard CO2 tanks is the most important feature — it’s the difference between $0.50 per liter and $0.10 per liter.

Bottle vs. Carafe

Plastic bottles are standard: lightweight, unbreakable, and PET plastic is safe for carbonated beverages. They expire after 2-4 years when the sealing mechanism wears out and starts venting CO2 mid-carbonation. Glass carafes look better, hold more volume (up to 1 liter vs. the standard 0.5-0.75 liter plastic bottle), and never wear out — but they’re heavy and breakable. Stainless steel insulated carafes keep drinks cold and carbonated for days but cost more. The choice is mostly about volume and aesthetics. If you drink carbonated water all day, a larger glass carafe saves you repeated trips to the machine.

Flavor System Compatibility

Most soda makers offer optional flavor syrups: either brand-name (SodaStream syrups, which cover cola, lemonade, root beer, and energy drinks) or third-party drops like Mio and Stur. The key question is whether you carbonate first and add flavor after (most machines do this — never add syrup before carbonating or the CO2 releases violently) and whether the machine includes a flavor bottle or attachment for pre-mixed drinks. Some newer models have a dedicated flavor compartment that mixes syrup inline, but these are more expensive and harder to clean.

Build Quality and Warranty

A soda maker is a pressure vessel with CO2 inside. Cheap machines use plastic components in the carbonating head that crack or wear out. Metal carbonating heads and stainless steel housings last longer. Check the warranty — two years is standard, five years indicates confidence. Replacement bottles are consumables and not covered under warranty, but the machine itself should last. The CO2 puncture pin (which breaks the seal on the CO2 cylinder) is the most common failure point.

Top 7 Soda Makers Reviewed

1. SodaStream Terra — Best Overall

The SodaStream Terra is the most refined entry-level soda maker SodaStream has made. The Snap & Lock carbonating bottle twists in and seals with a quarter turn — no more threading and wondering if it’s tight enough. The push-button carbonation is simple: short burst for light fizz, long press for aggressive bubbles. The Quick Connect CO2 cylinder snaps in without threading, which makes swapping canisters faster and less messy. The 60-liter CO2 cylinders are standard SodaStream exchange size. The machine comes with one carbonating bottle and a sample pack of flavor syrups. The body is mostly plastic but feels solid for the price.

CO2: Proprietary 60L Quick Connect | Bottle: 1L PET (Snap & Lock) | Carbonation: Push-button manual | Material: Plastic housing | Warranty: 2 years

Pros:

• Snap & Lock bottle is easier than threaded designs — no alignment frustration
• Quick Connect CO2 cylinder — no threading, just snap in
• Simple one-button operation — anyone can use it immediately
• Includes reusable carbonating bottle and flavor sample pack
• Compact footprint fits under most cabinets
• Widely available CO2 exchanges at Target, Best Buy, Walmart
• Affordable — typically $80-100

Cons:

• Proprietary CO2 cylinders — $30 exchange for 60L
• Plastic housing feels less premium than metal alternatives
• No pressure gauge or burp valve
• Standard SodaStream exchange means you’re locked into their ecosystem
• Bottle loses carbonation after 2-3 days in the fridge
• Carbonation consistency varies slightly on humid days

Verdict: The soda maker that does everything right at a fair price. The Snap & Lock bottle system is a genuine improvement over older SodaStream models. Buy this if you want the easiest path to home carbonation with the widest availability of CO2 refills.

2. Drinkmate Omnifizz — Best for Carbonating Anything

The Drinkmate Omnifizz is the only soda maker that can carbonate liquids other than water. Juice, iced tea, wine, lemonade, cocktails — if it’s a liquid, the Omnifizz will fizz it. The secret is the patented Fizz Infuser cap that attaches directly to the PET bottle and injects CO2 without the liquid shooting up into the machine. The pressurized carbonation reaches high levels thanks to the burp valve that releases excess pressure safely. It comes with two 1-liter PET bottles and a CO2 cylinder adapter that accepts both SodaStream 60L and standard paintball CO2 tanks with an adapter. This flexibility makes it the best value machine for heavy users.

CO2: SodaStream 60L or paintball with adapter | Bottle: 1L PET (Fizz Infuser cap) | Carbonation: Push-button with burp valve | Material: Plastic housing with metal carbonating head | Warranty: 2 years

Pros:

• Carbonates anything — juice, tea, wine, cocktails, not just water
• Burp valve allows higher carbonation pressure — fizzier results
• Fizz Infuser cap prevents liquid from entering the machine
• Compatible with SodaStream and paintball CO2 tanks
• Comes with two 1-liter bottles — keep one in the fridge
• Replacement bottles are inexpensive (~$8)
• Higher carbonation levels than most competitors

Cons:

• Fizz Infuser cap has more parts to clean than standard designs
• Plastic body still feels budget at the $100 price point
• Bottles are the limiting factor — carbonating anything acidic (juice) shortens bottle life
• Paintball tank adapter not included (sold separately)
• Heavier and wider than the Terra
• Not compatible with SodaStream’s flavor bottles

Verdict: If you want to carbonate anything beyond water — sangria, homemade sodas, carbonated cocktails — this is the only machine that does it safely. The burp valve and Fizz Infuser make it the most versatile soda maker available.

3. Aarke Carbonator III — Best Premium Design

The Aarke Carbonator III looks like it belongs in a design museum. It’s made from brushed stainless steel with a die-cast zinc carbonating head — zero plastic on the exterior. The lever-action carbonation mechanism is satisfying in a mechanical way: pull the lever and hold for desired fizz level, release, and wait for the hiss. The stainless steel body is heavy and stable on the counter. It comes with a PET carbonating bottle (1L) and uses standard SodaStream 60L CO2 cylinders. No electronics, no buttons, no branding — just a lever and a metal body.

CO2: Standard SodaStream 60L (threaded) | Bottle: 1L PET | Carbonation: Lever-action manual | Material: Brushed stainless steel + zinc | Warranty: 5 years

Pros:

• Beautiful design — this thing earns a spot on your counter for looks alone
• Stainless steel and zinc build will outlast plastic machines by years
• 5-year warranty shows confidence in build quality
• Lever action is smooth and satisfying
• Compatible with standard SodaStream CO2 cylinders (threaded)
• Compact — smaller footprint than most plastic machines
• Spare parts available directly from Aarke

Cons:

• Expensive — typically $180-200
• Uses threaded CO2 cylinders (not Quick Connect) — older SodaStream standard
• No burp valve — carbonation is a guessing game
• Single button/dial — less control than cheaper machines
• Bottle threading can be finicky to align
• No flavor bottle or included syrups

Verdict: The espresso machine of soda makers. It makes the same carbonated water as a $70 machine, but you’ll enjoy looking at it on your counter for the next decade. The 5-year warranty and replaceable parts make it the best long-term value if aesthetics matter.

4. SodaStream E-Terra — Best Electric

The SodaStream E-Terra electric soda maker removes the guesswork with three preset carbonation levels labeled Light, Medium, and Strong. Press a button and the machine injects CO2 automatically until it reaches the target level, then stops. No holding a button and counting seconds. The LCD display shows remaining CO2 level. The Snap & Lock bottle system is the same as the manual Terra. The Quick Connect CO2 cylinders snap in easily. The machine needs power (USB-C cable included), which limits counter placement to within reach of an outlet.

CO2: Proprietary 60L Quick Connect | Bottle: 1L PET (Snap & Lock) | Carbonation: 3 preset levels (electric) | Material: Plastic housing | Warranty: 2 years

Pros:

• Three preset carbonation levels produce consistent results every time
• LCD shows remaining CO2 — no guessing when the cylinder will run out
• Snap & Lock bottle and Quick Connect CO2 — no threading anywhere
• USB-C powered — works with standard phone chargers
• More consistent carbonation than manual pressing
• Great for parties — anyone can push a button and get perfect fizzy water

Cons:

• Needs USB power — limits counter placement
• More expensive than manual Terra ($130 vs $80)
• Plastic housing same as the $80 Terra
• Proprietary Quick Connect CO2 only (no third-party options)
• Electric components add potential failure points
• Cannot carbonate at custom levels — only the three presets
• Carbonation presets run slightly under toward the end of the CO2 cylinder

Verdict: The soda maker for people who want consistent results without thinking about it. Push a button, get perfect fizzy water every time. Worth the premium if you hate guessing at carbonation levels.

5. SodaStream Fizzi OneTouch — Best Value Electric

The Fizzi OneTouch is the previous-generation electric SodaStream that’s now deeply discounted. It offers the same three-level carbonation system as the E-Terra but uses the older push-to-lock bottle system and threaded CO2 cylinders. The result: same functionality for about 60% of the price. The body is plastic, the bottle is standard 1L PET, and the carbonation head is the same internals that SodaStream has refined over a decade. The machine is available in multiple colors. It’s been discontinued by SodaStream but still widely available new from retailers.

CO2: Standard SodaStream 60L (threaded) | Bottle: 1L PET (push-to-lock) | Carbonation: 3 preset levels (electric) | Material: Plastic housing | Warranty: 2 years

Pros:

• Significantly discounted — often $50-70 for an electric machine
• Three preset levels produce consistent results
• Threaded CO2 is more widely available than Quick Connect
• Available in multiple colors
• Same carbonation internals as current models
• Push-to-lock bottle system is proven and reliable

Cons:

• Discontinued — limited retailer stock
• Push-to-lock bottle is less secure than Snap & Lock
• Threaded CO2 cylinder is harder to install than Quick Connect
• No CO2 indicator light
• Plastic feels cheaper than the E-Terra
• No USB power — uses a barrel plug power adapter
• Color options are disappearing as inventory sells out

Verdict: The best value in electric carbonation — if you can find one. The three-level presets and widely available threaded CO2 make it a smart buy at $60. The older bottle system is the main compromise.

6. iSi Sodamaker — Best Prosumer

The iSi Sodamaker looks nothing like a consumer appliance — it’s a commercial-grade machine that sits on your counter like a piece of lab equipment. Instead of proprietary CO2 cartridges, it uses a standard 5-pound CO2 tank connected by a hose (included). A full 5-pound tank lasts roughly 200 liters of carbonated water, at a refill cost of $10-15. That’s $0.07 per liter, compared to $0.50 per liter for SodaStream. The machine uses glass carafes with a locking stainless steel carbonating head. Carbonation is controlled by a lever that releases CO2 in measured bursts. The build quality is restaurant-grade.

CO2: Standard 5-lb tank (included) — 200+ liters per refill | Bottle: 4 glass carafes (0.75L each) | Carbonation: Lever-action with pressure gauge | Material: Stainless steel + glass | Warranty: 2 years

Pros:

• Massive cost savings — $0.07/L vs $0.50/L for SodaStream
• Glass carafes never wear out and keep carbonation longer than PET
• Commercial-grade build quality — will outlast multiple consumer machines
• Pressure gauge shows exact carbonation level
• Can carbonate four carafes at once (rotating carafes)
• 5-lb tank lasts for months of heavy use
• Replacement glass carafes are inexpensive

Cons:

• High upfront cost — $250-300 plus the tank
• 5-lb CO2 tank is large — takes up cabinet space
• Glass carafes are breakable
• Heavy machine at 12 pounds (plus the tank)
• Overkill for light users who carbonate once a day
• No flavor system
• CO2 tank refill requires a trip to a welding supply or beverage distributor
• Steeper learning curve than consumer machines

Verdict: The soda maker for people who drink carbonated water constantly and care about cost per liter. It pays for itself in about 1-2 years compared to SodaStream refill costs, and the glass carafes keep water fizzy longer — noticeably longer. Not worth it for casual users.

7. KitchenIQ Sparkle Soda Maker — Best Budget

The KitchenIQ Sparkle is a no-frills manual soda maker that costs about half what a SodaStream does. It accepts standard wide-mouth PET bottles (sold separately, but standard 1L soda bottles also fit in a pinch), uses standard SodaStream-compatible 60L threaded CO2 cylinders, and carbonates water with a simple button press. The body is all plastic with a transparent carbonation chamber that lets you watch the CO2 inject. The lack of a branded bottle system means replacement bottles are cheap and widely available.

CO2: Standard SodaStream 60L (threaded) | Bottle: Standard wide-mouth PET bottles | Carbonation: Push-button manual | Material: Plastic | Warranty: 1 year

Pros:

• Cheapest option — typically $40-50
• Uses standard PET bottles — $3 replacements instead of $15
• Accepts standard SodaStream CO2 cylinders
• Transparent chamber is oddly satisfying to watch
• Compact and lightweight
• Gets the job done for basic carbonated water

Cons:

• All-plastic build feels cheap
• Carbonation consistency varies wildly
• No burp valve — must release pressure manually
• Bottle fit is imprecise — can leak CO2 during carbonation
• Only 1-year warranty
• Carbonation head is plastic and prone to wear
• No included bottles or flavor samples
• Fizz retention is poor compared to branded machines

Verdict: It works, but you get what you pay for. If you’re not sure whether you’ll use a soda maker and want the cheapest entry point, this is fine. If you know you’ll use it regularly, spend the extra $40 on a SodaStream Terra.

FAQ

How much money will a soda maker actually save me?

If you drink one liter of sparkling water per day from cans, you’re spending about $1-$1.50 per liter at grocery store prices. A soda maker brings that down to $0.10-$0.50 per liter depending on your CO2 setup. At one liter per day, a SodaStream user saves roughly $200-300 per year versus buying canned seltzer. The machine pays for itself in 3-6 months. The iSi Sodamaker with a 5-pound tank brings the cost down even further to approximately $0.07 per liter, which is about $30 per year for daily use. The main variable is how much you drink and whether you switch to standard CO2 tanks.

Can I use any CO2 cylinder with my soda maker?

Only if your machine explicitly accepts it. SodaStream’s proprietary Quick Connect cylinders only work with newer SodaStream machines (Terra, E-Terra). The threaded SodaStream cylinders fit all older SodaStream models and most third-party machines (Aarke, Drinkmate, KitchenIQ). Paintball CO2 tanks require an adapter and work with Drinkmate and some third-party machines. Full-size 5-pound or 10-pound commercial CO2 tanks require a hose adapter and only work with machines designed for them (iSi Sodamaker, or modified SodaStream machines using adapter kits available online). Never force a different CO2 connector — the threads and sealing mechanisms differ, and a mis-seated cylinder can leak or burst.

How long does carbonated water stay fizzy in the bottle?

PET plastic bottles with tight seals hold carbonation for 2-4 days in the refrigerator. Glass carafes with swing-top seals hold carbonation for 5-7 days. Stainless steel insulated carafes can hold carbonation for up to two weeks. The key variable is the seal quality — the PET bottles that come with soda makers have rubber gaskets in the cap that wear out over time. Replace the bottle every 2-3 years or as soon as you notice the fizz escaping faster than it used to. A simple test: fill the bottle with water, cap it, turn it upside down, and squeeze. Any water leaking from the cap means the seal is failing.

Can I carbonate juice or other liquids?

Only in machines explicitly designed for it. Standard soda makers (SodaStream, Aarke, iSi) can only carbonate water — carbonating juice or flavored liquids will cause violent foaming that shoots liquid into the machine’s internal CO2 pathway, which can corrode seals and void your warranty. The Drinkmate Omnifizz is the only consumer machine designed to carbonate any liquid, using its Fizz Infuser cap that prevents backflow. Some commercial machines (not tested here) also support direct carbonation. If you want carbonated cocktails or fruit sodas, buy the Drinkmate or use the standard method: carbonate plain water, then add flavor syrup or juice afterward.

How often do I need to replace the CO2 cylinder?

A 60-liter cylinder makes about 60 liters of carbonated water, which is roughly two months of daily use (one liter per day). A 130-liter cylinder lasts about four months. A 5-pound tank lasts 200+ liters — roughly seven months of daily use. The machine tells you when CO2 is running low because carbonation weakens and the hissing sound changes. Electric models like the E-Terra display remaining CO2 on the LCD. Manual models require you to track usage by weighing the cylinder (empty 60L weighs about 1.4 lbs, full is about 2.2 lbs). Always keep a backup cylinder if you use it daily — running out mid-afternoon is frustrating.

The Bottom Line

• Best overall: SodaStream Terra — the Snap & Lock bottle and Quick Connect CO2 make daily use noticeably smoother. Widely available refills and a fair price make it the default recommendation.
• Best for carbonating anything: Drinkmate Omnifizz — the only machine that safely carbonates juice, tea, and cocktails. The burp valve also produces the fizziest water in our tests.
• Best premium design: Aarke Carbonator III — buy this if you want a beautiful object on your counter that also makes fizzy water. The 5-year warranty is a bonus.
• Best electric: SodaStream E-Terra — three preset levels produce consistent results. Worth it if you hate guessing at carbonation levels.
• Best value electric: SodaStream Fizzi OneTouch — the same presets at a discount. Buy one while they’re still available.
• Best for heavy users: iSi Sodamaker — the cost per liter ($0.07) is unbeatable, and glass carafes keep water fizzy longer. The high upfront cost pays off within two years.
• Best budget: KitchenIQ Sparkle — works, costs $40, uses cheap replacement bottles. Fine for occasional use.

The sweet spot for most people is the SodaStream Terra or a discounted Fizzi OneTouch. If you drink sparkling water heavily, the long-term savings of the iSi Sodamaker with a 5-pound tank add up fast. And if you want to carbonate anything besides water, the Drinkmate Omnifizz is your only option.
