How to choose the right soda maker
Updated June 2026Independently researchedNo paid placement.
The best soda maker for you depends on whether you want to carbonate just water or a wider range of drinks, how much control you want over fizz level, and whether you prefer glass or plastic bottles. Most home users are happiest with a mid-priced model from a reputable brand like SodaStream or Drinkmate that uses screw-in CO2 cylinders and offers adjustable carbonation. Budget models work fine for basic sparkling water, while premium ones add extra features like glass carafes or built-in flavor infusion.
What type of soda maker should you buy?
The two main categories are basic carbonation machines and multi-drink carbonators. Basic machines carbonate plain water only, then you add flavor syrups afterward. Multi-drink models, like those from Drinkmate, let you carbonate juice, wine, or other liquids directly, thanks to a special venting system. If you mostly want sparkling water plus an occasional flavored soda, a basic model is simpler and cheaper. If you want to fizz up things like iced tea or lemonade, look for a model that explicitly supports carbonating other liquids. Focus on the bottle system. Some machines use reusable plastic bottles sized to fit under the carbonation head; others use glass carafes with a separate screw-top adapter. Plastic bottles are lighter and less fragile, but they absorb odors over time and must be replaced every couple of years. Glass carafes stay clean and look nicer on the counter, but they weigh more and cost more to replace if broken. Pick the material that fits your lifestyle.
How much carbonation control do you need?
Most soda makers let you adjust carbonation by pressing the carbonation button for a longer or shorter burst, or by using a simple twist knob. That basic control is enough for most people. You carbonate, taste, and add more fizz if needed. Entry-level machines often have a single button with a fixed release, which can limit your ability to make gently sparkling drinks or extra-strong seltzer. Some higher-end models include a pressure gauge or a multi-stage carbonation system that gives you repeatable results every time. These are useful if you are picky about fizz level or plan to make multiple drinks in one session. But for everyday use, a machine with a simple push-button that lets you press longer for more bubbles is perfectly fine.
Glass or plastic bottles: which is better?
Plastic bottles are standard on budget-friendly to mid-priced soda makers. They are lightweight, shatterproof, and designed to handle the carbonation pressure. The downside is that over time plastic can scratch, retain flavors from strong syrups, and lose its seal. Most manufacturers recommend replacing plastic bottles every two years or when they show wear. They are also not dishwasher safe, so hand washing is required. Glass carafes, often found on premium models or as add-ons, avoid those problems. They do not absorb smells, they are easy to clean, and they feel more like a nice serving piece. The trade-off is weight and breakability. If you have kids or a busy kitchen, glass may not be ideal. Some brands offer both options, so you can buy a plastic bottle for daily use and a glass carafe for entertaining.
Are flavor syrups worth the investment?
Brand-name syrups from SodaStream and others are convenient and widely available, with flavors ranging from classic cola to exotic fruit blends. They are formulated to mix well with cold carbonated water without fizzing over. However, they are more expensive per serving than using bulk syrups or making your own infusions. Many owners eventually switch to generic syrups, Torani, or simply add fresh citrus, herbs, or fruit puree to their sparkling water. If you plan to diet or watch sugar intake, check whether the brand offers diet or naturally sweetened options. Also note that some machines come with a starter pack of syrups, which can help you figure out what you like before buying larger bottles. You are not locked into one brand; you can use any syrup or flavoring as long as it is added after carbonation (or before, if your machine supports it).
How easy is it to clean and maintain a soda maker?
Daily cleaning is straightforward: wipe down the carbonation nozzle with a damp cloth and hand-wash the bottle with warm soapy water. Never put the bottle in the dishwasher unless the manufacturer specifically says it is dishwasher safe. The machine itself has no internal plumbing; the CO2 gas passes through a simple valve, so it rarely needs deep cleaning. Mineral buildup on the nozzle can be removed with a little vinegar on a cloth. The main ongoing task is replacing the CO2 cylinder. Most machines use small screw-in canisters that last roughly 60 liters of carbonated water, depending on how fizzy you like it. When empty, you exchange the cylinder at a participating store or mail it back for a refill. The process is quick and the cylinders are recyclable. Some newer models use larger, refillable tanks that last longer and lower the per-liter cost.
What should you expect to spend on a soda maker?
Prices vary widely. Entry-level machines are budget-friendly and come with a basic plastic bottle and one small CO2 cylinder. Mid-range models add nicer build quality, longer warranty, and sometimes a glass carafe or carbonation level indicator. Premium machines offer stainless steel accents, larger carbonation chambers, and compatibility with larger CO2 tanks that reduce long-term cost. The real cost over time is the CO2 refills and syrups. Refills are a recurring expense, but still significantly less than buying cases of bottled sparkling water. If you drink a liter of sparkling water a day, the per-liter cost can be a fraction of store-bought seltzer. Syrups add cost but are still cheaper per serving than canned sodas. Overall, the machine pays for itself within a year for regular sparkling water drinkers.
Frequently asked questions
Can I carbonate anything besides water?
That depends on the machine. Most basic models can only carbonate plain water; adding anything else before carbonation can cause foaming or clog the nozzle. Specialty units like Drinkmate allow carbonating juice, wine, or tea directly because they have a venting system that releases pressure safely. Always check the manufacturer’s recommendations before trying other liquids.
How long does a CO2 canister last?
A standard 60-liter cylinder typically lasts about 60 liters of carbonated water if you carbonate to a moderate fizz level. Heavy fizz users or larger bottles will get fewer uses. Many brands also offer 130-liter or larger canisters that last longer and reduce the per-liter cost.
Is homemade sparkling water cheaper than store-bought?
Yes, generally much cheaper. Even accounting for the cost of the machine and CO2 refills, a liter of homemade sparkling water costs a fraction of what you would pay for branded seltzer in cans or bottles. The exact savings depend on how often you use it, but most heavy users break even within a year.
Do I need special bottles for my soda maker?
Yes. Each soda maker brand requires specific bottles that fit its carbonation head. The bottles are designed to withstand the pressure of carbonation and to seal properly. You cannot use any random plastic bottle. Some models use a universal thread, but most are proprietary. Stick with the brand’s own bottles or verified compatible replacements.
Can I use my own flavors or syrups with a soda maker?
Absolutely. You can add any flavor after carbonation: fresh fruit slices, herbs, citrus juice, store-bought syrups like Torani, or homemade simple syrups. The only watchpoint is that syrups with a lot of pulp or particles may cause the carbonation to foam excessively. Stir gently and add flavor after the water is fizzy.
How often do I need to replace the bottle or other parts?
Manufacturers typically recommend replacing plastic bottles every two years because the plastic can develop micro-cracks that weaken over time. Glass carafes last indefinitely if not broken. The carbonation head and other machine parts rarely need replacement, though the carbonating nozzle may occasionally need cleaning. Check your machine’s manual for specific maintenance intervals.
