What is the main advantage of buying a duo?
Indigo Soda bundles combine practical accessories for making sparkling water at home and can help you save, depending on the set you choose.
The reusable bottle duo gives you two bottles at a lower price than buying them separately. This lets you keep one bottle of cold water ready to carbonate while the other already holds your sparkling water.
Bundles featuring a CO₂ cylinder and a reusable bottle bring these two accessories together in one purchase to complete your sparkling water setup.
Is the cylinder included in the product duos new?
Yes. The CO₂ cylinder included in our Indigo Soda bundles is new, filled, sealed, and ready to use. It can carbonate up to 60 litres of water, depending on your preferred carbonation level.
You do not need to provide an empty cylinder for this initial purchase. Once your cylinder is empty, you can exchange it for a full one at an Indigo Soda exchange location near you.
Can I choose the colors of the bottles in the bottle duo?
Colour choices depend on the combinations offered for the reusable bottle duo and their availability. Our sets feature our most popular finishes.
Before ordering, check the Indigo Soda reusable bottle duo product page to confirm the colours included and the available options.
Are duos a good gift idea?
Yes. Indigo Soda bundles make practical gifts for someone who already owns a compatible sparkling water maker and wants to add to their setup.
The reusable bottle duo lets them keep one bottle of cold water ready to carbonate while the other already holds a sparkling drink. A CO₂ cylinder and reusable bottle bundle brings together two useful accessories for everyday use.
These sets also encourage making sparkling water at home and help reduce the need to buy single-use bottles.
Before giving a bundle as a gift, check that both the cylinder and the bottle are compatible with the recipient’s sparkling water maker.
