CO2
How can I tell if my Thirsti™ Drink System is out of CO2/Gas?
The sparkling button will change from white to orange when the CO2 cylinder has approximately 25, 12oz drinks remaining. The sparkling button will remain orange until the CO2 cylinder is replaced and the indicator is reset. To reset the indicator, replace the CO2 cylinder and then hold the sparkling button until it turns white.
How do I install the CO2 cylinder in my Thirsti™ Drink System?
Remove the tamper seal and black cap from CO2. Start by opening the CO2 door at the back of the unit. Swing the CO2 cover out of the unit and remove the tamper seal and black cap from the CO2 canister. Insert the CO2 canister into the CO2 cover then apply gentle pressure to turn the canister to the right until tight.
Why did the Sparkling button turn Orange?
The sparkling button will change from white to orange when the CO2 cylinder has approximately 20, 12oz drinks remaining. The sparkling button will remain orange until the CO2 cylinder is replaced and the indicator is reset. To reset the indicator, replace the CO2 cylinder and then hold the sparkling button until it turns white. ONLY reset the indicator once a new CO2 canister has been installed.
Where can I get a new/full CO2 cylinder?
The Thirsti™ Drink System works with our Thirsti™ CO2 cannisters. Use the QR code on the CO2 door and on the Owner Manual to go to the Ninja Thirsti™ website from where you can reorder additional CO2 canisters. 
Is it safe to have CO2 cylinders in my home and how should they be stored?
Yes. It is safe to have CO2 cylinders in your home. They should be stored in an area less than 125F and never stored in a vehicle.
Can different company's CO2 cylinders be used with my Thirsti™ Drink System?
Other company's CO2 cylinders are not compatible with your unit to work properly. To ensure proper product performance we recommend Ninja Thirsti™ CO2. This is due to a difference in threading that is compatible with your Ninja Thirsti™.
Why do we recommend that you always have more than one cylinder?
We want you to enjoy fresh, fizzy drinks without interruption! We recommend keeping three CO2 canisters handy so that when one CO2 canister runs out, you simply swap the used canisters for full ones with the CO2 Refill Program.
Will my CO2 canister expire?
The CO2 does not expire but canisters do need to be checked for quality assurance purposes. Please check the date on the bototm of each canister to ensure it is not past this quality assurance timeframe.
Will high altitude have any effect on my cylinder and can I take my cylinder on a plane?
Elevation change will have no pressure effect on a CO2 canister. Most airlines and airport security prohibit the carrying of CO2 Canisters into a place.
What's the difference between purchasing a spare carbonating canister and the CO2 Refill membership?
With the CO2 Refill Club membership, you will save 30% on refills when sending back your used canisters. If you wish to opt into the CO2 Refill Exchange Program, simply order a Refill Exchange box to get your return process started.
How many drinks does the CO2 canister make?
Each Thirsti™ 60L CO2 Canister makes 50-100 12oz drinks, depending on the Sparkling level being used.
When do I need to order a new CO2 ?
It is recommended to order more CO2 before or as soon as your Sparkling button blinks Orange indicating there is 25% CO2 remaining.
How often will I need to replace my CO2 cylinder?
Each 60L CO2 canister will make approximately 100, 12oz carbonated drinks. When the Sparkling button blinks orange there is only 25% CO2 left in the canister. This will make approximately 25, 12oz drinks. We recommend joining our refill club to never run out of bubbles.
Where can I exchange my empty gas cylinder?
Please visit ninjakitchen.com to join the Thirsti™ Refill Club and exchange your empty CO2 canister.
Where does the CO2 come from and is it safe?
Ninja Thirsti™ CO2 is made from renewable biomass generating food grade CO2.

Can my Ninja Thirsti™ CO2 canister be used with a different company's Sparkling Water Maker?

Why do I need to use Ninja Thirsti™ box to return/exchange my CO2 canister?
The Ninja Thirsti™ return/exchange box contains all legal markings that are required to ship CO2.
Where can I recycle my CO2 cylinders if I no longer use them?
We encourage all empty CO2 canisters to be returned via the Refill Club however we understand this may not always be the best option. CO2 canisters can be recycled at most recycling centers as scrap metal. This does require your CO2 canister to be completely empty.
How do you ensure that Ninja Thirsti™ carbonating cylinders that get refilled are clean, and can I refill the gas cylinders on my own?
Each refill cylinder is re-sealed for quality assurance.
Why did one of my CO2 canisters run out quicker than the other?
Always ensure your Ninja Thirsti™ CO2 canister is tightly installed. CO2 canisters from other brands may lead to leakage and fast loss of CO2. If a CO2 canister is not tightly twisted in place CO2 leakage may also occur. This will cause the CO2 canister to run out of CO2 quickly.
Why is the orange light on even after replacing the CO2?
When the Sparkling button lights up Orange this is an indication that your CO2 is starting to run low and it's recommended to join the Thirsti™ CO2 Refill Club or order new Thirsti™ CO2 Canisters.
Once you install a new CO2 canister hold down the Sparkling button until it turns back to it's original white LED. You have now reset the CO2 Low indicator.

What are sulfites and how are they used in the Flavor Drops?
We use sulfites in some of our Thirsti flavor pods to help maintain the quality of our drinks. The sulfites used in our pods are food-safe compounds commonly used as preservatives in beverages. The FDA requires beverages with more than 10 ppm to call out sulfites on their label, as some individuals have a sensitivity. Our flavor pods are concentrated formulas and some (as labeled) may have more than 10 ppm sulfites before they are diluted in your machine to make your beverage. However, we are confident that our flavors – when used to make a finished, diluted drink following our machine instructions – contain sulfite levels below 10 ppm FDA labeling threshold.
