10 Best Carbonated Water Makers 2025 in the United States

The SodaStream Terra Sparkling Water Maker Bundle is a solid choice for anyone wanting to easily make sparkling water at home without needing electricity. Its biggest strength lies in the Quick Connect CO2 system, which allows fast and simple insertion of the CO2 cylinders without twisting, making carbonation very straightforward. The included 3-pack of 60L CO2 cylinders offers a decent amount of sparkling water before needing replacement, which is convenient for regular use. The 1L bottle is BPA-free, dishwasher safe, and reusable, supporting sustainability by reducing single-use plastic waste.

With a sleek black design and ergonomic carbonation button, the Terra fits nicely in most kitchens and feels comfortable to operate. Its cordless, manual operation means no worrying about plugs or batteries. However, the machine only works with SodaStream Quick Connect CO2 cylinders, so you are locked into their specific cartridges for refills, which might limit flexibility and cost options.

The size is fairly compact (about 8 by 5 by 17 inches) but it does weigh nearly 8 pounds, so while it’s portable, it’s not ultra-light. Maintenance is minimal—mainly cleaning the bottle and occasionally replacing the CO2 cylinder. For those new to sparkling water makers or looking for a user-friendly, eco-friendly option, the Terra bundle offers good value with its easy carbonation and reusable bottle. If you want a machine with more bottle size options or compatibility with multiple CO2 types, you might need to look elsewhere. This product performs well for straightforward sparkling water on demand.

The aarke Carbonator III is a stylish and well-built sparkling water maker featuring a sleek stainless steel design that adds a premium feel to your kitchen. It offers precise and smooth carbonation thanks to its redesigned nozzle, letting you control how fizzy your water gets, which is great if you enjoy tailoring bubbles to your taste. One big plus is its eco-friendly approach—the included CO2 cylinder is made from renewable resources, helping reduce environmental impact. This model is cordless and manual, meaning you don’t need electricity, and you can place it anywhere without worrying about power outlets. The 800 ml BPA-free reusable bottle is a decent size for individual or small family use, but it might be a bit small if you want to serve larger groups or fill multiple glasses at once.

It supports several CO2 cartridge types, giving some flexibility, though it’s not compatible with all popular cartridge systems like the Sodastream pink cap quick connect, which could limit swapping cartridges. Setting up is straightforward as it comes with everything needed right out of the box, including cleaning tools, which keeps maintenance simple. On the downside, since it’s manual, you’ll need to put some effort into pumping the carbonation, which might not suit everyone. Also, while the design is elegant, the size is compact but could feel a bit heavy or bulky compared to plastic alternatives. For those seeking a durable, environmentally conscious sparkling water maker with precise fizz control and who do not mind manual operation, the aarke Carbonator III represents a solid choice.

The Ninja Thirsti Drink System is a versatile soda maker that lets you customize your sparkling water experience easily. It offers three carbonation levels plus the option for still water, so you can pick the fizz that suits your taste. One nice feature is its flexibility in drink size, accommodating cups from 6oz up to 24oz, which is handy if you want a smaller drink or a larger one to share. The system also stands out with over 25 unique zero-calorie flavor options and the ability to mix flavors, giving you plenty of choices beyond plain sparkling water.

In terms of design, it uses a 60-liter CO2 cylinder that is straightforward to install and refill, allowing for efficient carbonation and less frequent cartridge changes compared to many competitors. The removable 48oz water reservoir is temperature sensitive, helping to keep your water cool before carbonation. The machine is relatively compact, although at 13.5 pounds it’s not the lightest, but it fits well on most kitchen counters.

Maintenance is user-friendly, with fewer plastic waste concerns since it replaces single-use bottles and saves money in the long run by cutting down on store-bought drinks. The system requires the included proprietary flavor drops and CO2 cartridges, which means ongoing costs and possible limited availability outside of the Ninja ecosystem. The Ninja Thirsti suits users looking for a customizable, flavorful sparkling water system with moderate maintenance and a good balance of convenience and variety.
