SodaStream CO2 cylinders are 100% contaminants checked individually, 100% pressure checked and only the highest food-grade CO2 used. SodaStream has 100 % control throughout the lifetime of each cylinder. (No loss of control through outsourcing). SodaStream does have a "0" - 0 cylinder failure!

On average, the SodaStream CO2 cylinders will make 60 litres of sparkling water. This number could be more or less depending on the amount of carbonation used when making your drink. A household of four soda drinkers might need to replace a cylinder every 6-8 weeks, depending on usage.

There are a number of indications that show your CO2 cylinder is empty:

On a kitchen scale, an empty cylinder weighs about 800g or less.When you press the carbonating button you will not see any gas going into your bottle of water.Even after repeated presses you don't reach the 'buzzing' sound.The carbonating button may stay down.The carbonator splutters, showing you have run out of CO2.

Please note: SodaStream recommends that you keep a spare CO2 cylinder in the cupboard so that when one cylinder runs out, you simply swap the empty cylinder for the full one. That way, you'll keep enjoying fresh, fizzy drinks and can return the empty CO2 cylinder as you order your next gas refill.

When your CO2 cylinder runs out of gas, order an EXCHANGE CO2 cylinder online. SodaStream will collect your empty one and give you a new one at the same time. These empty CO2 cylinders will be returned to our filling facility where we clean them, inspect them, and refill them. Alternatively, CO2 cylinder exchanges and other soda-making supplies are available at our retail stores and our Sparkling Centre in Singapore.

SodaStream licensed CO2 cylinders are filled with food-grade CO2 in compliance with exacting FDA standards for food and beverage safety. Other unauthorized refilling sources may not be in compliance with these standards and could possibly introduce toxins into your CO2. Furthermore, unauthorized filling machines may cause damage to the CO2 cylinders. Damaged SodaStream CO2 cylinders will not be accepted for return by SodaStream. Any CO2 gas filling by parties other than SodaStream authorized filling stations violates the User License.

The CO2 cylinder has a 5-year life span. You can find the expiration date on the top of the cap. Store your CO2 cylinder in a temperate environment to keep it fresh!

No, SodaStream provides a guarantee only for our own eco-friendly products.

We cannot speak for the products of any other company, which may damage the maker. We've had numerous cases where customers find that their makers have been damaged by the use of such unauthorized products. Unfortunately, we will not be able to repair nor replace such makers. Do note that the use of cylinders or carbonating bottles other than those approved by SodaStream for use with your Sparkling Water Maker will void the warranty.

Only SodaStream CO2 cylinders carrying identification and a nylon shrink wrap bearing the SodaStream brand name bought from our official website & licensed partners should be used. Do exercise caution with suspect 'compatible' products in the market.  

Unless you are traveling in your own private jet, please confirm withe the professional personnel. SodaStream advises against carrying CO2 cylinders on an airplane. Airlines have restrictions that prohibit compressed gas cylinders in carry-on items as well as in checked baggage.

The CO2 cylinders contains compressed carbon dioxide (CO2). Compressed gas has a tendency to expand when it is exposed to a source of heat for prolonged periods of time. Therefore, the CO2 cylinders must not be exposed to sources of heat (such as travel in the trunk of a car) or placed right next a heat source such as an oven, stove or fireplace. It is important to always store the CO2 cylinders unit in a cool and dry environment. Every cylinder is fitted with a unique safety valve which will safely release the gas in the unlikely event the pressure in the cylinder rises.

Absolutely. SodaStream CO2 cylinder are manufactured to exacting specifications that include many unique safety features to protect consumers. CO2 cylinder are safe at virtually any altitude (our customers in the Swiss Alps can attest to that!) and are specially equipped with a safety valve that will harmlessly release the gas in the unlikely event that the pressure within the cylinder rises above threshold levels. Please do not expose your CO2 cylinder to extreme heat (such as travel in the trunk of a car, or right next to an oven, stove or fireplace.) Please see above for more information on CO2 cylinder safety.

The SodaStream Cylinder is provided under licence and remains the property of SodaStream. When you do not need the CO2 cylinders any longer, we have a global return policy where customers may return their empty CO2 cylinders without an exchange for a return fee of S$2.50 per cylinder as stated on the cylinders. This can be done at our Sparkling Centre @Ubi, as well as these partner stores : Selffix DIY and ToTT

Not at all. Normally after carbonating a bottle of water, there is a small amount of gas in the Sparkling Water Maker. The tilt of the bottle releases that gas as a safety measure. The amount of gas lost is not problematic, as this gas has already passed through the water as a part of the normal carbonation process. If you hear gas escaping while you are carbonating your drink (i.e. while pressing the fizzing button) you may need to screw the CO2 cylinder more tightly to the Sparkling Water Maker. If the gas continues to escape continuously, please contact our friendly staff at our Customer hotline to assist you in servicing of the unit.

Make sure your carbonating bottle is filled just to the "Water Fill Line" indicator (the lower of the two pronounced ridges near the neck of the bottle.)

Other possible causes for overflow :

Trying to fizz a liquid other than waterAdding drink mix to the bottle before attempting to fizzNot tilting the carbonating bottle when adding the drink mixYou have just changed to a new bottle of CO2 cylinder

If you still have trouble with overflow after checking these tips, please contact Customer Support for advanced troubleshooting!

Flat water may indicate that you have not carbonated properly. First, ensure that the CO2 cylinder has been screwed tightly into the maker. This important video may be helpful and save you a trip down to SodaStream Sparkling Centre.

You can then proceed to twist the carbonating bottle into place, press the carbonating button ALL THE WAY DOWN in firm short bursts. You will hear a hissing sound at first. Continue to press the button in firm short bursts until you hear a LOUD BUZZ. The loud buzz indicates the first level of carbonation. Three loud buzzes will achieve average carbonation.

Another tip: Make sure you use very cold water for carbonation. Cold water (from the refrigerator) holds carbonation much better than cold water from the tap. We recommend keeping carbonating bottles full of water in your refrigerator so they are always ready to go when you want a fresh soda!

The SodaStream system is designed to allow users to choose how sweet and fizzy they want their drinks. If you have used the recommended amount of drink mix in your drink, try adding a little more until you find the level of flavour you like best.

Fill only to the level of the water fill line, indicated by the blue arrows near the neck of the carbonating bottle. Overfilling the carbonating bottle will result in a more diluted flavour.Try a full cap of drink mix -- or more -- if you like a stronger or sweeter flavour.Shake well after adding the drink mix to ensure that it has completely mixed with the sparkling water.
