How Much Is a CO2 SodaStream Refill?

Ever found yourself in a pickle, running out of gas in the middle of a party or on a hot summer day?

We've all been there.

But what if we told you there's a more cost-effective and convenient way to keep your water carbonator bubbling?

In this blog, we'll unravel the mystery behind the CO2 cylinder, helping you understand its various sizes and how to determine when it's empty.

How Much Does It Cost To Refill a Cylinder?

There are two primary ways to approach a gas canister refill in the UK:

• Official Exchange Program: This option is offered by the manufacturer itself and authorised retailers. You exchange your empty canister for a pre-filled one, typically paying a fee that covers the CO2 refill and a potential deposit for the new canister. You usually need to either drop the canister off with the company or pay for postage or a courier service to collect it. 
• Third-Party Refill Services: There are independent businesses (like ours!) that offer a refill service where they re-fill your existing canister with CO2. This is much more affordable and convenient for a number of reasons, which we'll explain below. 

Official Exchange Program Costs

Prices for official exchange programs can vary depending on the retailer and the size of the canister. Here's a breakdown:

• Canister Size: Most manufacturers offer one size in the UK: 60L 
• Retailer: Prices can differ slightly between authorised retailers like Argos, Currys PC World, and John Lewis.
• Deposit: You might need to pay a deposit for the new canister, which is usually refunded when you return the empty one during your next refill.

The average manufacturer charges around £12.99 per bottle plus shipping. They usually charge a deposit for the bottle or a fee of around £10 if the bottle is not returned within 45 days.

Third-Party Refill Services

Independent refill services (like ours) can offer a lower price per refill compared to the official exchange program. However, not all refill services are equal. Make sure that they follow the proper guidelines, including: 

• Safety Checks: Your provider should perform the necessary safety checks and avoid overfilling or using expired canisters. 
• CO2 Quality: Ensure the service uses food-grade CO2, which is essential for safe consumption.

With a subscription to a refill service, buying more cylinders upfront can bring the cost per refill down. While potentially cheaper, it's crucial to ensure they use food-grade CO2 and follow proper safety procedures. Always research the reputation and safety practices of such refill companies before using them.

CO2 YOU charges just £39.98 for four canisters, making it £9.99 per bottle - and that includes the cost of collection and delivery. 

Understanding the Refill Process

Whether you choose the official program or a third-party service, here's what goes into a refill:

• Canister Inspection: In a safe and controlled environment, the canister is checked for any damage or signs of wear and tear.
• CO2 Depletion: The remaining CO2 is removed from your canister.
• Refilling: The canister is filled with fresh, food-grade CO2 to its designated capacity.
• Leak Testing: The refilled canister undergoes a final check for leaks before being returned to you.

What Are Canisters Refilled With?

Water carbonator canisters are filled with carbon dioxide (CO2), specifically food-grade CO2. This is the same type of CO2 used to carbonate beverages like soda and sparkling water. It's safe for consumption and gives your water that refreshing fizz.

Here's a breakdown of why CO2 is used:

• Creates Bubbles: CO2 gas dissolves in water, creating the tiny bubbles that give sparkling water its signature fizz.
• Safe for Consumption: Food-grade CO2 is safe to ingest and doesn't alter the taste of your water significantly.
• Widely Used: This type of CO2 is commonly used in the beverage industry and is generally considered harmless.

UK Retailers Offering Canister Refills

Prices can differ depending on where you get your refill. Check major supermarkets, kitchenware stores, or even online retailers for the best deals. Bear in mind these retailers are not always the most affordable or convenient option, and there have been stock issues with refills in the past. CO2 YOU will send two canisters to your door (and collect them) for just £29.96! 

The Process of Refilling Your CO2 Cylinder

Ready to refill your cylinder? It’s easy. Here's how it works at CO2 YOU:

Choose the Quantity

The first step in the CO2 refill process is deciding on the quantity. This is crucial as it directly impacts the cost and frequency of refills.

You can opt for a single refill cylinder or go for a bulk purchase. Single refills are ideal for occasional users, while bulk purchases suit frequent users.

Buying in bulk often comes with discounts, making it a cost-effective choice in the long run. But remember: CO2 cylinders require proper storage to ensure safety and maintain quality.

Choose Delivery Frequency

After you've decided on the quantity of CO2 cylinders you need, the next step is to choose your delivery frequency.

You have the flexibility to choose a frequency that suits your usage. The options range from every month to every six months.

The frequency you choose will also determine when you need to return the empty cylinders. For instance, if you opt for a monthly delivery, you'll need to return the cylinders after a month plus 30 days.

It's worth noting that the delivery frequency you choose can also impact the shipping cost. Choose wisely and make sure the frequency aligns with your usage to avoid any unnecessary costs or delays.

Can You Refill Your SodaStream Yourself?

No, you should not  refill your SodaStream yourself. Refilling your SodaStream canisters at home poses significant safety risks, including the potential for gas leaks, improper sealing, and even explosions. It's crucial to have the refilling process handled by professionals who follow stringent safety protocols. Third-party refill services, like CO2 YOU, are a much safer and more reliable option, ensuring your canisters are refilled correctly and safely.

How Do You Know if Your Soda Stream CO2 Cylinders Are Empty and Need Refilling?

The first sign that your CO2 cylinder is empty is a noticeable decrease in the fizziness of your drinks.

Another indicator is the weight of the cylinder. An empty cylinder weighs around 540 grams, while a full one is approximately 920 grams.

Keeping track of how many litres you've carbonated can also help. A standard cylinder should carbonate about 60 litres of water.

If you've been keeping tabs on your carbonation consumption, you'll have a fair idea of when your cylinder is likely to run out.

Final Thoughts on CO2 Refills

Refilling your water carbonator doesn't have to break the bank. Knowing which parties offer the best deals (and the most convenient) exchanges will go a long way towards saving you money while keeping the delicious fizzy drinks flowing.
