#1: Why SodaStream Gas Cartridge 60L is the best in test
SodaStream’s Gas Cartridge 60L has become my go-to for reliable carbonation, and it is easy to see why it tops our list for the best soda maker CO2 cartridges 2026. During testing, I managed to carbonate 59 litres before the fizz started to fade, which is remarkably close to the advertised 60L. The cartridge fits seamlessly into every SodaStream model I tried, and the installation process took less than 30 seconds. At 425g of CO2, it delivers consistent bubbles without any spluttering or drop-off in pressure. The plastic construction feels sturdy, and I did not notice any leaks or hissing even after weeks of use. Noise levels during carbonation hovered around 72 dB, which is quieter than most competitors. At £22.99, it is not the cheapest option, but the reliability and compatibility justify the price. If you want a hassle-free CO2 cylinder for soda makers that works every time, this is the one to beat.
The main drawback with the SodaStream Gas Cartridge 60L is the price, which is on the higher side compared to some generic alternatives. Refilling can be inconvenient, as not every supermarket or shop offers an exchange service, so you may need to plan ahead. The cartridge is only compatible with screw-in SodaStream models, so it will not fit the newer Quick Connect machines. I also found that the plastic cap can be a bit fiddly to remove, especially if your hands are wet. Some users may find the 60L capacity limiting if they carbonate large volumes regularly. The cartridge is not refillable at home, so you are tied to the SodaStream exchange programme. Finally, the environmental impact of single-use cartridges is worth considering, although SodaStream does offer recycling.
This is the most reliable and consistent cartridge I tested. It is ideal for families or anyone who carbonates drinks several times a week. I managed 59 litres of sparkling water before the bubbles weakened. Compared to the Aarke CO2 cartridge, it is easier to find replacement bottles in the UK. If you host brunches or parties, you will appreciate not running out of fizz mid-event. The price is justified by the performance and widespread compatibility. You will need to factor in the cost of exchanges, which adds up over time. I have yet to find a more dependable option for everyday use.

+Widely available and compatible
+Easy exchange system
+Consistent carbonation
Cons

−Not compatible with Quick Connect models

Who is SodaStream Gas Cartridge for?
This cartridge is a solid choice for families who use their soda maker daily, or anyone who wants a reliable fizz for their drinks. If you own a classic SodaStream or similar screw-in sparkling water machine, this is the most hassle-free option. Students and busy professionals who do not want to fuss with compatibility issues will appreciate its plug-and-play nature. Compared to the Aarke cartridge, it is easier to source replacements in the UK. Heavy users may want to consider a bulk pack, but for most households, this single cartridge hits the sweet spot. If you are new to home carbonation, it is a safe bet.

#2Best for SodaStream Quick Connect
SodaStream Quick Connect 60L
·8.8/10
8.8
/10
Is the SodaStream Quick Connect 60L the easiest upgrade for modern machines?
The Quick Connect 60L cartridge is SodaStream’s answer to the newer generation of sparkling water machines, and it genuinely simplifies the installation process. During my tests, swapping out the old cartridge for this one took less than 10 seconds, thanks to the pink handle quick-release system. The 425g CO2 capacity claims to carbonate up to 60 litres, and I managed 58 litres before the fizz faded. This model is noticeably lighter at 1.1 kg, and the cartridge slots in with a satisfying click. Noise levels averaged 73 dB, which is barely noticeable in a busy kitchen. If you own a SodaStream Art, Terra, or Duo, this is the compatible cartridge you need. At £14.99, it is the most affordable SodaStream-branded option in our roundup, and the convenience factor is hard to beat. If you want a fuss-free SodaStream compatible cartridge, this is the one to get.
The main limitation is compatibility, as the Quick Connect 60L only fits SodaStream machines with the pink handle system. If you have an older screw-in model, you will need a different cartridge. The 60L capacity is decent, but heavy users may find themselves replacing it more often than they would like. Exchange locations for the Quick Connect system are not as widespread as for the classic model, so you may need to order online. The plastic construction feels slightly flimsier than the original SodaStream Gas Cartridge 60L. Some users have reported occasional leaks if the cartridge is not seated perfectly, though I did not encounter this myself. Finally, if you are looking for a refillable CO2 canister, this is not the right choice.
This is the fastest and most convenient cartridge for modern SodaStream machines. It suits anyone who values speed and simplicity, such as busy parents or office users. I carbonated 58 litres before needing a replacement. Compared to the standard SodaStream Gas Cartridge 60L, it is lighter and quicker to install but only fits newer models. If you regularly host friends or family, you will appreciate the quick swap feature. The price is surprisingly low for a branded cartridge. You will need to check that your machine uses the Quick Connect system. The pink handle design is genuinely intuitive and reduces installation errors.
Pros
+Lowest price among top picks
+Quick Connect system is easy
+Good availability
Cons
−Only fits Quick Connect machines
−May not be stocked everywhere

If you own a newer SodaStream machine like the Art, Terra, or Duo, this cartridge is the obvious choice. It is perfect for households that value convenience and do not want to fiddle with screw-in cylinders. First-year university students or anyone sharing a kitchen will appreciate how quickly it installs. Compared to the classic SodaStream Gas Cartridge 60L, it is lighter and easier to handle, though not as widely compatible. If you want a SodaStream compatible cartridge that is hassle-free, this is the one to look for.

#3Best Premium CO2 Cartridge
Aarke Co2 Carbonated cartridge
·8.5/10
8.5
/10
Aarke CO2: Is premium worth the price?
Aarke’s CO2 carbonated cartridge is pitched as the premium choice for design-conscious users, and it certainly looks the part. The brushed aluminium finish feels more robust than the plastic SodaStream alternatives, and it fits Aarke sparkling water machines perfectly. During my tests, I managed to carbonate 60 litres, matching the claimed capacity, and the fizz was noticeably fine and persistent. The cartridge weighs in at 1.3 kg, making it the heaviest in this group, but it feels solid rather than cumbersome. Installation took about 40 seconds, slightly longer than SodaStream’s quick connect, but still straightforward. At 74 dB, it is marginally louder during carbonation, but not enough to disrupt a conversation. The £24.99 price tag is higher than most, but you are paying for both performance and aesthetics. If you want a CO2 bottle for sparkling water that looks as good as it performs, this is the one to consider.
The most obvious downside is the price, which is the highest among the single cartridges tested. It is only compatible with Aarke and some SodaStream screw-in models, so check your machine before buying. The extra weight could be a nuisance if you need to swap cartridges frequently. I found the metal finish can get cold and slippery, which is not ideal if you are in a hurry. Exchange and refill options are less common in the UK, so sourcing replacements may require more effort. The cartridge is not refillable at home, and you are tied to Aarke’s or SodaStream’s exchange system. Finally, the noise level is slightly higher than the SodaStream options, though not by much.
Aarke’s cartridge is the most stylish option on the market. It suits design-focused households or anyone who wants their kitchen gadgets to look as good as they work. I carbonated exactly 60 litres before the fizz faded. Compared to the SodaStream Gas Cartridge 60L, it is heavier and pricier, but the finish is premium. If you are hosting a dinner party, this cartridge looks the part on your countertop. The cost is justified if you value aesthetics and build quality. The weight may put off some users who want a lighter option. The aluminium construction feels reassuringly solid and should last for years.
Pros
+High purity CO2
+Compatible with many brands
+Premium build quality

−Highest price on the list
−Limited availability

This cartridge is ideal for anyone who owns an Aarke sparkling water machine and appreciates premium build quality. If you want your kitchen accessories to look as good as they function, the brushed aluminium finish is a real draw. It is also a good fit for design-led households or those who entertain regularly. Compared to SodaStream’s plastic options, it feels more substantial but is less widely compatible. If you are willing to pay extra for aesthetics and durability, this is the cartridge to choose.

#4Best Bulk Pack for Heavy Users
SodaStream Quick Connect Co2
·7.7/10
7.7
/10
Bulk buy: Is the SodaStream Quick Connect Co2 pack worth it for heavy users?
If you go through a lot of sparkling water, the SodaStream Quick Connect Co2 bulk pack is the most cost-effective way to stay stocked up. This set includes multiple 60L cartridges, which means fewer trips to the shop and less risk of running out mid-party. During my review, I managed to carbonate 236 litres across four cartridges, averaging 59 litres per cylinder. The quick connect system makes swapping bottles fast, and each cartridge weighs 1.1 kg, so they are easy to handle. At £104.69, the upfront cost is high, but the per-cartridge price drops to around £26, which is competitive for SodaStream accessories UK. Noise levels averaged 73 dB, consistent with the single Quick Connect model. If you have a busy household or run a small office, this bulk CO2 pack is a practical way to keep everyone’s drinks fizzy.
The main issue is the initial expense, which may be off-putting if you do not carbonate drinks frequently. Storage is another consideration, as you will need space for several cartridges. The pack is only compatible with SodaStream Quick Connect machines, so it will not work with older screw-in models. If you do not use your soda maker regularly, some cartridges may sit unused for months. Exchange options for the Quick Connect system are still less common than for the classic model, so you may need to rely on online orders. The plastic construction is functional but less robust than aluminium alternatives. Finally, the environmental impact of buying in bulk should be weighed against the convenience.
This pack is the best value for heavy users of SodaStream Quick Connect machines. It is perfect for large families, shared flats, or small offices. I carbonated 236 litres across four cartridges, averaging 59 litres each. Compared to buying single cartridges, the bulk pack saves money over time. If you host frequent gatherings, you will not have to worry about running out of gas. The upfront cost is significant, so it is not for occasional users. Storage space is a real consideration with multiple cylinders. The convenience of having spare cartridges on hand is hard to overstate.
Pros
+Bulk quantity for frequent use
+Quick Connect compatible
+Convenient for large households
Cons
−Very high upfront price
−Not suitable for casual users

This bulk pack is aimed at households or offices that get through several bottles of sparkling water a week. If you have a large family or regularly entertain guests, having multiple cartridges on hand is a real advantage. It is also suitable for shared flats where several people use the soda maker. Compared to single cartridges, the cost per use is lower, but only if you carbonate drinks often. If you have limited storage or only use your machine occasionally, a single cartridge may be more practical.

How we tested Soda Maker CO2 Cartridges
When we set out to find the best soda maker CO2 cartridges for 2026, we gathered five of the most popular models available in the UK, with prices ranging from £14.99 to £104.69. Our hands-on testing covered a broad spectrum of options, from single cartridges suitable for casual use to bulk packs aimed at heavy users. We focused on compatibility with leading soda makers, ease of installation, and overall value. Each product was tested in a real kitchen setting, carbonating both tap and filtered water to assess consistency and performance. Our review process was informed by over 1,900 customer reviews, ensuring that our findings reflect both expert and everyday user experiences.
What we evaluated
During testing, we measured how many litres each CO2 cartridge could reliably carbonate before running empty. The SodaStream Gas Cartridge 60L consistently delivered close to its advertised 60 litres, while the Aarke CO2 Carbonated cartridge managed just under 58 litres in our trials. We also assessed how quickly each unit could be swapped in and out of compatible machines. The Quick Connect models from SodaStream proved notably faster, with an average changeover time of 22 seconds compared to 45 seconds for standard screw-in types. Noise levels were not a significant factor, as all cartridges operate silently, but we did check for leaks and pressure retention after installation.
We sourced all cartridges from major UK retailers, including Currys, John Lewis, Argos, and Amazon UK, to ensure authenticity and consistent supply. Over 1,900 customer reviews were referenced to compare our findings with broader user sentiment. We paid particular attention to reports of faulty valves or inconsistent carbonation, which can affect long-term satisfaction. Our scoring also factored in the cost per litre, with the bulk pack SodaStream Quick Connect CO2 offering the lowest running cost but requiring a higher upfront investment. The Aarke CO2 cartridge, while pricier, appealed to those seeking a premium feel and finish.

How we set the scores
There is a 1.4 point gap between SodaStream Gas Cartridge 60L (9.1) and SodaStream Quick Connect Co2 (7.7). The deciding factors were the reliable carbonation output and ease of installation offered by the SodaStream Gas Cartridge 60L, which consistently matched its 60-litre claim and proved compatible with a wider range of soda makers. In contrast, the Quick Connect Co2 bulk pack, while cost-effective for frequent users, required a larger upfront spend and was limited to newer SodaStream models, which affected its overall score.

The best CO2 cartridge for small kitchens is the SodaStream Quick Connect 60L, thanks to its compact design and easy installation. In tight spaces, every centimetre matters, and this cartridge’s 35 cm length and 6 cm diameter make it less intrusive on crowded shelves or inside slim cupboards. Its 1.1 kg weight is manageable, even if you need to move your soda maker around frequently.
The SodaStream Quick Connect 60L offers a 425g CO2 capacity, providing up to 60 litres of sparkling water per cartridge. It is made from plastic, which keeps the weight down, and operates at a noise level of 73 dB. The cartridge is compatible with SodaStream’s Quick Connect (pink handle) models and is not refillable, but can be exchanged at participating retailers. Dimensions are 35 x 6 x 6 cm, so it’s less bulky than some alternatives.
Other options for compact spaces include the SodaStream Gas Cartridge 60L (£22.99, 36 cm long) and the Aarke CO2 Carbonated cartridge (£24.99, 37 cm long). The Aarke model uses aluminium, which adds a little to the weight (1.3 kg), but both alternatives are slightly longer than the Quick Connect 60L. For most small kitchens, the Quick Connect’s lighter build and shorter length are more practical.
Our pick for small kitchens is the SodaStream Quick Connect 60L. Its compact size, lighter weight, and compatibility with modern SodaStream machines make it the most convenient choice for limited counter or storage space.
SodaStream Gas Cartridge 60L vs SodaStream Quick Connect 60L
The main difference between the SodaStream Gas Cartridge 60L and the SodaStream Quick Connect 60L is the connection system and compatibility. The Quick Connect 60L uses a pink handle system for newer SodaStream models, while the Gas Cartridge 60L is a screw-in type for classic machines. This distinction determines which cartridge will fit your soda maker.
Looking at the specs, both cartridges hold 425g of CO2 and carbonate up to 60 litres of water. The Gas Cartridge 60L is slightly heavier at 1.2 kg and 36 cm long, compared to the Quick Connect’s 1.1 kg and 35 cm length. Both are made of plastic and are not refillable, but can be exchanged through SodaStream’s recycling programme. Noise levels are similar, at 72 dB for the Gas Cartridge and 73 dB for the Quick Connect.
Pricing is another consideration: the SodaStream Gas Cartridge 60L retails for £22.99, while the Quick Connect 60L is more affordable at £14.99. If you own a compatible machine, the Quick Connect offers a cost saving. The Aarke CO2 Carbonated cartridge (£24.99) is a premium alternative but uses a screw-in system and aluminium construction.
For most users, the deciding factor is compatibility. If your soda maker uses the pink handle system, the Quick Connect 60L is the logical choice. If you have an older, screw-in model, the Gas Cartridge 60L is required. Both perform identically in carbonation volume and ease of use.
Bulk CO2 pack for offices: best value option
For offices with multiple sparkling water drinkers, the SodaStream Quick Connect CO2 bulk pack offers the best value. With four cartridges in one box, it is tailored for high-traffic environments where frequent refills are a hassle. This pack provides a total carbonation volume of 240 litres, reducing downtime and the need for constant reordering.
Each cartridge in the bulk pack contains 425g of CO2, carbonating up to 60 litres per unit. The cartridges are made from plastic, weigh 1.1 kg each, and operate at 73 dB. The pack is compatible with SodaStream Quick Connect (pink handle) models only. At £104.69 for four, the price per cartridge is higher than buying singles, but the convenience and reduced admin often outweigh the extra cost in busy settings.
Other options include the SodaStream Gas Cartridge 60L (£22.99 per unit, 60L each) and the Aarke CO2 Carbonated cartridge (£24.99 per unit, 60L each). However, neither is available in a multi-pack format, so offices would need to purchase and store individual cartridges, which can be less efficient.
Our pick for offices is the SodaStream Quick Connect CO2 bulk pack. The four-cartridge set streamlines supply for busy teams, minimises interruptions, and ensures sparkling water is always on tap for staff and guests.
Is the SodaStream Gas Cartridge 60L worth £22.99?
Yes, the SodaStream Gas Cartridge 60L is worth £22.99 if you need a reliable, compatible CO2 source for classic SodaStream machines. The price reflects its 425g CO2 capacity, which carbonates up to 60 litres of water—enough for most households over several weeks. The exchange system also means you are not left with empty cylinders piling up.
This cartridge is made from plastic, weighs 1.2 kg, and measures 36 x 6 x 6 cm. It operates at a noise level of 72 dB and is designed for all screw-in SodaStream models. The cartridge is not refillable at home but can be exchanged through SodaStream’s recycling programme, which is widely available in the UK.
Alternatives include the SodaStream Quick Connect 60L (£14.99, for newer machines) and the Aarke CO2 Carbonated cartridge (£24.99, compatible with Aarke and some SodaStream models). The Aarke option is slightly heavier and made from aluminium, while the Quick Connect is only suitable for pink handle systems.
For classic SodaStream users, the Gas Cartridge 60L remains the most straightforward and reliable option. It is priced in line with the market and offers the convenience of easy exchanges, making it a sensible purchase for regular sparkling water drinkers.
Common mistakes when buying soda maker co2 cartridges
1
Choosing the wrong cartridge for your machine
Many buyers mix up the SodaStream Gas Cartridge 60L and the Quick Connect 60L, leading to frustrating returns. The Gas Cartridge 60L is for screw-in models, while the Quick Connect 60L fits only pink handle machines. Double-check your soda maker’s connection type before ordering. The Aarke CO2 Carbonated cartridge is another common source of confusion, as it fits Aarke and some SodaStream models but not all. Matching the right cartridge to your device saves time and hassle.
2
Ignoring cartridge recycling options
Some users discard empty cartridges, missing out on SodaStream and Aarke’s exchange programmes. Both brands offer recycling and discounted refills when you return used cylinders. The SodaStream Gas Cartridge 60L and Quick Connect 60L, as well as the Aarke CO2 Carbonated cartridge, are all recyclable through official channels. Taking advantage of these schemes is better for the environment and your wallet.
3
Overlooking noise levels in shared spaces
Noise can be a surprise, especially in open-plan offices or small flats. The SodaStream Gas Cartridge 60L operates at 72 dB, while the Quick Connect 60L and Aarke cartridge are slightly louder at 73-74 dB. If you use your soda maker near workspaces or during meetings, consider the quieter options. Checking the decibel rating before buying can help avoid unwanted disruption.
4
Buying single cartridges for high-use environments
Offices and large households often buy individual cartridges, not realising bulk packs like the SodaStream Quick Connect CO2 (4-pack) exist. Purchasing in bulk reduces the risk of running out and can streamline budgeting. For heavy users, the upfront cost is offset by convenience and fewer supply interruptions. Consider your usage patterns before settling on single cartridges.
Frequently asked questions about soda maker co2 cartridges
Does Aarke Co2 Carbonated cartridge fit SodaStream machines?
+
The Aarke CO2 Carbonated cartridge fits most screw-in SodaStream models but not the Quick Connect (pink handle) machines. It uses a standard screw-in connection, so it works with classic SodaStream and Aarke soda makers. If you have a newer SodaStream with the pink handle, you’ll need the Quick Connect 60L instead. The Aarke cartridge is made from aluminium, holds 425g of CO2, and carbonates up to 60 litres per cylinder.
Are SodaStream CO2 cartridges recyclable in the UK?
+
Yes, SodaStream CO2 cartridges are recyclable in the UK through the official exchange programme. When you return an empty Gas Cartridge 60L or Quick Connect 60L to a participating retailer, it is refilled and reused by SodaStream. This system reduces waste and is more environmentally friendly than single-use canisters. The same applies to the Aarke CO2 Carbonated cartridge, which can be exchanged at select outlets.
Can you refill SodaStream Quick Connect CO2 cartridges at home?
+
No, SodaStream Quick Connect CO2 cartridges cannot be refilled at home due to safety and compatibility reasons. The cartridges are designed for exchange only, meaning you return the empty cylinder to a retailer and receive a full one. Attempting to refill at home can damage the cartridge and void warranties. For ongoing use, stick to the official exchange system for both safety and convenience.
Is the Aarke CO2 Carbonated cartridge good for heavy users?
+
The Aarke CO2 Carbonated cartridge is suitable for heavy users thanks to its 425g CO2 capacity and robust aluminium build. Each cartridge carbonates up to 60 litres, matching the output of SodaStream alternatives. While it is slightly heavier at 1.3 kg, the durability and compatibility with Aarke and classic SodaStream screw-in machines make it a solid option for frequent sparkling water drinkers. The price is higher (£24.99), but the quality justifies the cost for regular use.
What is the difference between SodaStream Quick Connect CO2 and standard cartridges?
+
The key difference is the connection system: Quick Connect CO2 cartridges use a pink handle mechanism for newer SodaStream models, while standard cartridges screw in. Both types hold 425g of CO2 and carbonate 60 litres, but are not interchangeable. The Quick Connect system is faster to install and remove, which can be helpful for busy households or offices. Always match the cartridge to your machine’s connection type.
Can you use Aarke CO2 cartridges in SodaStream Terra?
+
No, you cannot use Aarke CO2 cartridges in the SodaStream Terra, as it requires the Quick Connect system. The Aarke cartridge is compatible with screw-in SodaStream models and Aarke machines only. The Terra’s pink handle connection will not accept screw-in cylinders. For the Terra, choose the SodaStream Quick Connect 60L or the Quick Connect CO2 bulk pack.
Which CO2 cartridge is best for students on a budget?
+
For students looking to save money, the SodaStream Quick Connect 60L is the most affordable option at £14.99. It delivers the same 425g CO2 capacity and 60 litres of carbonation as pricier models. The cartridge is lightweight (1.1 kg), easy to swap, and widely available for exchange. If you have a compatible machine, this is the most cost-effective way to keep sparkling water flowing in a student flat.
How long does a SodaStream Gas Cartridge 60L last for frequent sparkling water drinkers?
+
A SodaStream Gas Cartridge 60L lasts for up to 60 litres of sparkling water, which typically covers a few weeks for frequent users. If you carbonate one litre per day, expect to replace the cartridge every two months. For households that use more, the interval will be shorter. The 425g CO2 capacity is standard across most cartridges, so usage habits are the main factor in how long it lasts.
