Quick answer
The 90 Day Carbonation Bundle is a starter kit plus two bonus CO2 exchange cylinders and a prepaid return box, so you can keep sparkling about three times longer before dealing with exchanges. Choose it if you want a lower-maintenance first setup and predictable CO2 returns. Skip it if you already own a maker or prefer to buy cylinders one at a time.
What the bundle actually includes
You get a SodaStream sparkling water maker Starter Kit, two bonus CO2 exchange cylinders, and a convenient return box. The bundle is built around the idea that the first 90 days should not include a trip to a store or a separate cylinder order. Instead, the cylinders and the return packaging arrive together, so you can focus on carbonating and flavoring rather than logistics.
How the 90-day CO2 return process works
After 90 days, put your empty CO2 cylinders in the provided pre-paid return box and send it back via USPS, or leave it in your mailbox to be picked up. That prepaid return is the main convenience feature of this bundle. It removes the need to find a retailer that accepts cylinder exchanges or to pay for shipping separately. The tradeoff is that you are committing to the return process rather than simply swapping a cylinder locally.
Bundle vs cylinder exchange: the real difference
cylinder exchange
A standard cylinder exchange usually means you bring one empty cylinder and leave with one full one. This bundle front-loads the value by including two bonus exchange cylinders and the return box up front. If you carbonate daily, that extra capacity matters because you are not making a trip every few weeks. If you carbonate occasionally, the bundle may hold more CO2 than you can use in 90 days, which makes a single-cylinder exchange simpler.
Flavor add-ons that pair well with the bundle
The bundle covers carbonation, not flavor. If you want variety without added sugar, the bubly burst Watermelon Lime drink mix is a single-flavor option with zinc and no added sugar. For a more flexible setup, bubly drops Peach Natural Flavor Essence lets you make about 12L of bubly sparkling water from one 40ml bottle. For alcohol-free cocktails and mocktails, the Crafted Mixers Variety 3 Pack includes Grapefruit & Elderflower, White Peach & Ginger, and Pineapple & Jalapeno. These are separate purchases, so factor them into your total cost if plain sparkling water is not your goal.
Decision rules for the 90 Day Carbonation Bundle
- You carbonate at least a few times a week: The two bonus cylinders are designed to keep you sparkling about three times longer than a single cylinder, so frequent users get the most from the bundle. Buy the bundle if daily or near-daily sparkling water is your habit.
- You want to avoid store trips for CO2: The prepaid return box lets you send empty cylinders back via USPS or leave them for mailbox pickup after 90 days. Choose the bundle if convenience outweighs the commitment to the return process.
- You already own a SodaStream maker: The bundle includes a Starter Kit, so you would be paying for hardware you already have. Skip the bundle and look for a standalone cylinder exchange instead.
- You carbonate less than once a week: Two bonus cylinders may last well beyond 90 days, which can make the return timing awkward or unnecessary. A single-cylinder exchange is simpler for very light use.
